THE RESEARCH REGISTER
Open questions.
Clear boundaries.
Explore 272 records currently listed: 215 original inventory records + 57 additional reviewed claims, including applications needing closer review, descriptions with missing information and proposals that are not being pursued.
Evidence labels describe the proposed application. Established scientific principles are explained in the field-guide chapters. An available chapter or a successful calculation does not establish that a proposed device works.
The register is separate from the 47-chapter programme. Items set aside remain visible so that scope decisions can be examined. Further scientific review is in progress. This directory lists the claims currently recorded; it does not establish that every possible idea has been identified.

A calculated result is not a judgment
A computer can apply rules to recorded information, but a calculated result does not establish what someone intended or whether a judgment is fair.

Two positions remain in tension: one assigns criminal-responsibility decisions to computers; another says intention cannot be known and describes decisions based on harm, circumstances and personal characteristics. No decision algorithm, test data or validation is supplied.
What would clarify it
Retain this as an excluded proposal. The useful question is how to distinguish recorded facts, assumptions and judgments; no automated sentencing, punishment or coercive intervention is proposed.
This item remains listed outside the current chapter programme.
Related content: A score needs a purpose. Explains why a score needs an independently defined purpose and criterion; it does not audit automated criminal-responsibility decisions or establish sentencing fairness in any jurisdiction.
Can a material preserve a record of past radiation?
A mark in a material is an observation. Estimating an earlier radiation field also requires knowing how the material responds, how old it is and what other processes could leave similar marks.
Why this remains unresolved or set aside
One proposed interpretation names cesium-oxide minerals and suggests that traces can preserve information about earlier radiation. The material identification and measurement are not independently verified; neither an ancient radiation intensity nor a biological consequence has been established. No exposure or protection guidance follows.
What would clarify it
Before assessing a historical-radiation method, obtain identified samples, trace measurements, calibration, dating and uncertainty. No such dataset is supplied here.
This item remains listed outside the current chapter programme.
Related content: From radiation to inherited change: several separate questions. The radiation chapter separates a proposed radiation history from the later biological conclusions drawn from it. It does not verify a mineral-based measurement of past radiation.

A wavelength-like quantity is assigned a value near 1.87 m, but its definition, radiation reference, measurement procedure, frame convention and uncertainty are missing. A precise number alone does not establish a reproducible length standard.
What would clarify it
Document the reference, conditions, comparison method and uncertainty before assessing whether different measurements reproduce the same length. The linked chapter explains this measurement question; it does not validate the proposed unit.

Some languages express grammatical distinctions differently. A claim about missing articles or how gender is marked needs many interpretable examples, not just a statement that the rules exist.
Why this remains unresolved or set aside
No reliable word list, contrasting forms or sufficiently documented corpus establishes the proposed article and gender rules. The terminology itself is ambiguous.
What would clarify it
Collect independently interpretable examples and document segmentation, meanings and counterexamples. Keep article use and gender marking as separate questions.
This item remains listed outside the current chapter programme.
Related content: One example cannot establish a grammar. Uses a limited teaching example to explain why grammar claims need interpretable examples and counterexamples; it does not test the proposed article or gender rules or provide a validated corpus.
What makes a vehicle able to walk?
Articulated legs can move a body only if their motion, support and power supply work together. The proposal includes a drawing of a legged vehicle and a separate mention of large vehicles with multiple legs; neither shows how they keep their balance or carry a load.
Why this remains unresolved or set aside
No gait, actuator specification, load, power requirement or stability measurements are supplied. The later mention adds no mechanism or dimensions. Repeating the description and referring to other robot-navigation models do not fill those gaps.
What would clarify it
Specify the motion, contact forces and energy assumptions before comparing a bounded model with measurements. No vehicle performance or safety is demonstrated.
This item remains listed outside the current chapter programme.
Related content: Static balance on three supports. Explains how a fixed, level three-point support carries a stationary vertical load and why an outside load projection cannot be supported by upward-only contact forces. It does not model walking, gait transitions, actuators, power demand or dynamic vehicle stability, and it demonstrates no vehicle performance or safety.
What would establish a new plant variety or species?
A new-looking flower does not by itself establish a new species. A plant-development claim needs a clear account of what changed and how that change was identified.
Why this remains unresolved or set aside
No lineage, development method, taxonomic evidence, measured traits or comparative observations are supplied. The mechanism cannot be inferred from the stated objective.
What would clarify it
Clarify whether the claim concerns a variety, a hybrid or a species, and identify the observational evidence needed to distinguish them. No biological procedure or successful result is provided.
This item remains listed outside the current chapter programme.
Related content: Evolution has several mechanisms. Explains general mechanisms of evolutionary change; it does not document plant breeding, establish a new flowering-plant species, or validate this source claim.
Does watching wildlife show whether it is recovering?
Seeing an animal more often can mean there are more animals—or that they are easier to spot. Repeated, consistent surveys help tell those explanations apart.
Why this remains unresolved or set aside
A conservation concept calls for surveying and protecting wildlife considered at risk, but gives no survey method, starting count, chance of seeing an animal, named threat or measured outcome. It does not establish that a protection plan succeeded.
What would clarify it
Choose the species, places, season and observation rules. Record detections and non-detections on repeat visits so a model can estimate how often animals are missed. Keep occupancy (sites where a species occurs) separate from abundance (number of animals). To assess whether protection helped, measure outcomes over time and use a justified comparison.
Read the related chapter: Seeing more does not always mean more animals
What would an eradication claim have to demonstrate?
One proposal targets all pathogenic virus varieties; a broader promise concerns all infectious diseases, including those resistant to existing treatments. These scopes differ: infectious diseases are not limited to viruses. Neither proposal supplies a demonstrated eradication method. A further account repeats broad pathogen-control and immune-system claims without adding a method or an observed outcome.
Why this remains unresolved or set aside
The proposals give no identified intervention, defined pathogen and host scope, surveillance evidence or observed outcome. A common mechanism is not established. The broader promise does not by itself specify individual-patient treatment or demonstrate successful eradication.
What would clarify it
Clarify each target and evidence standard separately before evaluating the claims. Preserve the difference between reducing disease, treating an individual and stopping ongoing transmission. This entry offers no biological intervention, treatment or operational eradication procedure.
This item remains listed outside the current chapter programme.
Related content: Keep track of the water. Do not call it shelf life.. This film example concerns a specific surface-transfer model. It does not demonstrate treatment or eradication of infections in people or populations.
What would support a cancer-prevention claim?
Preventing a cancer, detecting it and treating it are different goals. A claim that a technique prevents harmful genetic changes needs a defined intervention and evidence that it reduces a clearly measured outcome. A further account links cancer control to understanding and deliberately changing nuclear DNA sequences, without supplying a target, intervention record or demonstrated clinical result.
Why this remains unresolved or set aside
No molecular target, intervention, population, comparison or clinical outcomes are supplied. The stated achievement is not demonstrated, and the description provides no usable treatment.
What would clarify it
Define exactly what is claimed and examine appropriate existing evidence before assessing it. No personal prevention recommendation, therapy or experimental procedure follows from this proposal.
This item remains listed outside the current chapter programme.
Related content: From radiation to inherited change: several separate questions. This radiation example separates possible DNA and cellular effects from later evidence about populations. It is not evidence for the proposed cancer-prevention intervention or a clinical outcome.
Sensing movement is not the same as enjoying it
Proprioception is the sense of body position and movement; the vestibular system contributes to balance and orientation. Detecting a small movement, feeling comfortable and becoming sleepy are separate outcomes.
Why this remains unresolved or set aside
The proposal claims unusually fine movement discrimination and strong pleasant responses to acceleration, alongside discomfort during floating. It supplies no defined stimuli, sensory thresholds, comparison groups or measured sleep outcomes.
What would clarify it
Keep movement discrimination, balance and orientation, and emotional or soothing effects separate. Each would need its own clear outcome and appropriate evidence; no exposure exercise or sleep recommendation is provided.
This item remains listed outside the current chapter programme.
Related content: Different ways to sense the world. Explains established orientation cues; it does not measure the proposed fine proprioceptive thresholds, comfort or sleep effects under acceleration, or discomfort while floating.
Reading handwriting is an inference
A handwriting system turns strokes into candidate characters. Storing an image of a page is a different task from correctly reading its words.
Why this remains unresolved or set aside
No character set, labelled examples, segmentation method or recognition results are supplied. A description of automatic conversion does not establish accuracy.
What would clarify it
Define the writing system and assess recognition on independently labelled examples, including unfamiliar handwriting and ambiguous marks. Keep the original image available for checking.
This item remains listed outside the current chapter programme.
Related lesson: From a recording to a checked transcript
Explains standard text edit-distance scoring with constructed word and character examples. It does not read handwriting or audio, recover the proposed recognition method, or establish measured accuracy or novelty.
Recording a voice is not transcribing it
An audio recording preserves a signal. Transcription interprets that signal as readable language, with possible errors when sounds, speakers or words are unclear.
Why this remains unresolved or set aside
No vocabulary, language rules, noise conditions, speaker coverage or measured transcription errors are supplied. The recording function does not validate the recognition function.
What would clarify it
Specify the intended language and conditions, then compare transcripts with independently checked references. Preserve the audio and indicate uncertainty rather than silently treating every word as certain.
This item remains listed outside the current chapter programme.
Related lesson: From a recording to a checked transcript
Explains standard text edit-distance scoring with constructed word and character examples. It does not read handwriting or audio, recover the proposed recognition method, or establish measured accuracy or novelty.
Can one signal describe the whole metabolism?
Metabolism includes many chemical processes in the body. Inferring them from a brain-related electrical signal would require showing which measurable process each feature represents.
Why this remains unresolved or set aside
The proposal claims broad metabolic information without defining target quantities, sensors, calibration, specificity or independent reference measurements. It does not establish a diagnostic tool.
What would clarify it
Separate specific measurable targets and examine whether the proposed signal distinguishes each from other causes of variation. No personal interpretation, diagnosis or clinical procedure is provided.
This item remains listed outside the current chapter programme.
Related content: One target is not the whole metabolism. Explains why broad physiological claims need defined targets and independent reference measurements; it validates no specific biomarker, metabolic readout or diagnosis.
A skin pigment needs evidence for its intended use
A pigment can change the appearance of skin. Describing it as chemically inert does not establish that it is suitable around a surgical procedure.
Why this remains unresolved or set aside
No formulation, sterility evidence, skin or tissue compatibility data, or assessment of interference with the intended procedure is supplied. The claimed compatibility remains unverified.
What would clarify it
Define the material and intended use before evaluating appropriate compatibility evidence. This entry provides no application instructions, product recommendation or clinical safety assurance.
Related content: Compatibility depends on the intended use. This chapter explains general evidence needs only; it supplies no evidence about the claim, no clinical result, and no assessment that the described pigment is suitable.
Sending measurements is not establishing a diagnosis
A remote system can receive measurements, but deciding what they mean is a separate task. A diagnosis and a treatment recommendation each require evidence appropriate to the intended patient and condition.
Why this remains unresolved or set aside
One proposed system sends temperature, a quantity called “tension” (possibly pressure in context; sensor and units are unspecified), sweat acidity and cardiac-signal information to a network for diagnosis and prescription. No defined conditions, measurement accuracy, reference diagnosis, independent clinical assessment or patient outcomes are supplied.
What would clarify it
Clarify the intended clinical question and what “tension” is intended to measure. Evaluate measurement quality, diagnostic performance and treatment benefit separately. No personal diagnosis, prescription or care guidance follows from this description.
This item remains listed outside the current chapter programme.
Related content: Sending measurements is different from making a diagnosis. Separates sensor transmission from clinical interpretation and treatment; no clinical evaluation or patient outcome is supplied for the proposal.
What can an old recording tell us about a person?
Recordings and written accounts can preserve what someone said or did. Inferring their intelligence, brain structure or mental health from those records is a separate claim that needs independent evidence.
Why this remains unresolved or set aside
The proposed assessment draws conclusions from recordings, biography and statements, but supplies no defined dataset or assessment criteria. Selection bias, context and alternative interpretations are not addressed.
What would clarify it
Define the narrow question and check the completeness and context of the records. Separate observations about recorded speech or writing from unsupported conclusions about a person’s health or brain.
This item remains listed outside the current chapter programme.
Related content: A score needs a purpose. Provides context on intended purpose and independently defined criteria; it does not evaluate historical records or establish intelligence, brain structure or mental-health inferences about a person.
An unprovided method for changing light conditions
A proposed method is said to protect vision when moving between very different lighting conditions. Brightness changes and ultraviolet exposure are different factors; a protection claim must specify which effect it addresses.
Why this remains unresolved or set aside
The description promises a later explanation but provides no method, material, measurement or performance data. Its claims about injury and the inadequacy of ordinary sunglasses are not established by the description.
What would clarify it
Recover the missing explanation before evaluating any proposed mechanism. Define the intended effect and look for appropriate independent evidence; this entry provides no eye-care advice or recommendation for protective equipment.
This item remains listed outside the current chapter programme.
Related content: Light depends on wavelength and detector. Provides context on wavelength bands and optical measurements; it does not describe the missing vision-protection method or establish claims about injury, brightness adaptation or sunglasses.
A compact oxygen store is not a complete breathing system
A wearable device is proposed to supply breathing oxygen from oxygen stored as an extremely cold solid. Storing oxygen and delivering a suitable breathing supply are separate engineering problems.
Why this remains unresolved or set aside
The description gives no thermal-control design, delivery regulation, usable duration or test results. Its small wearable form does not establish that the proposed system can support breathing.
What would clarify it
Look for a defined system boundary and independent evidence for storage, delivery and operating limits. This is an undocumented apparatus claim, not a construction guide or equipment recommendation.
This item remains listed outside the current chapter programme.
Related content: A resource loop needs a complete boundary. Uses a simplified water-recovery model to show why a life-support system needs defined inputs and outputs; it does not model cryogenic oxygen storage, breathing delivery, indoor-air removal or health benefit.
What would complete gestation outside the body require?
One proposal describes fertilization and complete gestation outside the maternal body as an option in cases of maternal illness. A separate claim says external gestation has never been performed, while describing laboratory equipment and a detached biological uterus as technically viable.
Why this remains unresolved or set aside
The difference between the earlier permitted exception and the later never-performed statement remains unresolved. Neither account supplies a support system, exchange mechanism, developmental observations or independently assessed outcomes. Claimed feasibility, permission and actual use are separate questions.
What would clarify it
Clarify the proposed stages, equipment and practice using independently assessable evidence. Keep laboratory equipment and a detached biological uterus distinct, and do not equate fertilization outside the body with complete gestation. No reproductive procedure or clinical advice is provided.
This item remains listed outside the current chapter programme.
Does gravity explain how we perceive space?
Our experience of space is not the same thing as a geometric description of the world. This proposal goes further: it claims that gravity acts on nerve endings to generate that experience.
Why this remains unresolved or set aside
No receptor, physical coupling, measurable neural signal or comparison with other sensory explanations is specified. The role of gravity in balance does not by itself establish this broader claim about spatial perception.
What would clarify it
Define the claimed signal and a prediction that distinguishes this explanation from alternatives. Look for existing independent observations before treating the proposal as a sensory mechanism; no human experiment or intervention is proposed.
Read related context: Gravity provides an orientation cue. It does not establish the broader claim about spatial perception.
A hidden message or a pattern found by searching?
Ordinary words can carry a concealed message if a decoding rule has been agreed. Finding an interesting pattern after trying many rules is a different situation: the number of attempts matters when judging whether chance could explain it.
Why this remains unresolved or set aside
A partial rule is supplied: words with an even number of letters give 0, and words with an odd number give 1. That produces bits, not yet an independently recovered message. The exact selected text, rules for counting letters, grouping of bits, decoding codebook and recovered output remain unavailable. The claim that chance is very unlikely also lacks a defined comparison model and an account of the alternative interpretations tried. Separate claims propose that a voice reveals a speaker’s “neuromental structure” and that a stone inscription was chosen to influence its recipient. No audio, validated inference method or measured influence is supplied. Those claims are distinct from recording/transcribing speech and from the described text-decoding claim; none is independently confirmed.
What would clarify it
Specify the exact text and complete extraction and decoding steps before checking new examples. Account for all attempted interpretations and compare results against a declared chance model. No concealed message has been independently recovered here.
This item remains listed outside the current chapter programme.
Related content: A match can become easy to find. Shows how trying many rules can produce chance patterns; it does not validate the proposed hidden message without the exact input text and fixed decoding rules and independently checked result.
Food capsules selected by blinking
The proposed wearable system would move food capsules along a tube to the mouth, with blink sequences selecting capsules and a second tube carrying a nutrient liquid. It describes a different delivery mechanism from a heated-drink dispenser.
Why this remains unresolved or set aside
No dimensions, delivery rates, control-error measurements, cleaning specification or independently assessed outcomes are supplied. Describing a control gesture does not show that the system can reliably distinguish intentional commands from ordinary blinking.
What would clarify it
First recover a complete specification and any existing performance records. Separate capsule transport, command recognition and suitability for the intended user; no working assistive device or clinical benefit has been established here.
This item remains listed outside the current chapter programme.
Related content: A positive signal is not a certain identification. Provides a general example of signal classification and false positives; it does not demonstrate intentional-blink recognition, capsule delivery, safety or clinical suitability.
Can perceived brightness use one fixed correction factor?
The proposal says an object is about ten times brighter than it appears because the eye absorbs much of the incoming light. This combines a claim about light transmission with a claim about visual perception.
Why this remains unresolved or set aside
No measured quantity, wavelength range, viewing conditions or observations support the stated multiplier. The description does not define how its physical brightness and apparent brightness would be compared.
What would clarify it
Define the quantities being compared and recover any supporting measurement records. Keep optical transmission, light reaching the retina and reported visual sensation separate; the proposed number is not a validated correction factor.
This item remains listed outside the current chapter programme.
Related content: Light measurements depend on wavelength and response. Provides context on the physical light spectrum and detector response; it does not study visual psychophysics, retinal transmission or establish a fixed brightness-perception factor.
What could a compact hidden-object scanner identify?
A proposed sensing terminal worn in a ring would describe the shape and material of hidden solid objects. Its sensing mechanism is not specified.
Why this remains unresolved or set aside
No signal type, source, detector, resolution or material-identification evidence is supplied. An initial report of finding nothing does not establish sensitivity or prove that the interior was empty.
What would clarify it
Define separately what is detected, located and identified, then seek calibration and reference-object records. Do not assume this is the same instrument as a later underground imaging proposal.
This item remains listed outside the current chapter programme.
Related content: Separate the limits before comparing a camera. Explains how interaction, detector, resolution and calibration constrain imaging; it demonstrates no ring scanner, hidden-object detection or material-identification performance.
Could many small resonators form a useful microphone?
The proposal combines 734 sensing cells to cover a claimed 16–19,500 Hz sound range with a nearly uniform response. The lowest-frequency cells are described as not self-resonant.
Why this remains unresolved or set aside
No measured frequency-response curve, noise level or calibration supports the claimed performance. The stated threshold below 6 dB and cutoff at 118 dB lack a defined decibel reference, so they cannot be treated as measured sound limits.
What would clarify it
Specify how each cell converts sound into a reading and how the readings are combined. Recover response, noise, distortion and calibration records before comparing the proposed microphone with an established instrument.
This item remains listed outside the current chapter programme.
Related content: Small listeners. Different favourite notes.. Illustrates independent damped mechanical responses with assigned parameters. It does not validate the proposed microphone, electrical sensitivity, noise floor, cell count or bandwidth.
What would a helium-based radiation detector measure?
A proposed liquid-helium sensing element would scan a very broad range of radiation and record frequency, amplitude, phase and time. These are proposed outputs, not supplied measurements.
Why this remains unresolved or set aside
The description does not explain how incoming radiation becomes a reading or how the outputs are calibrated. Its range ends with an ambiguous beta label, which cannot be assumed to define one continuous electromagnetic band.
What would clarify it
Clarify which radiation types and quantities are intended, the sensing mechanism and its usable range. Seek detector-response and calibration records; liquid helium alone does not establish a universal detector.
This item remains listed outside the current chapter programme.
Related content: What happens to the original beam?. Shows a bounded photon-attenuation and detection example; it does not model a liquid-helium instrument, universal radiation detector, beta detector calibration or the claimed range.
What could reveal nuclear structure inside a pressurized sample?
An unspecified instrument is claimed to examine atomic nuclei while a sample is under pressure, without inserting a probe into it. This is a proposed measurement capability, not a supplied result.
Why this remains unresolved or set aside
No signal, sensing method, resolution, calibration or measurements explain how the claimed nuclear information was obtained. Applying pressure does not itself demonstrate that nuclear structure was measured.
What would clarify it
Identify the physical quantity actually observed and how it would support the claimed interpretation. Seek calibrated instrument measurements and reference comparisons before treating this as a demonstrated measurement.
This item remains listed outside the current chapter programme.
Related content: What belongs with a measurement?. General measurement literacy: an observed quantity, method, reference and uncertainty are required before an instrument reading can support an interpretation. This section does not model nuclear structure, pressure-dependent nuclear observations or the proposed instrument.
What explains a reported telephone interruption?
A reported telephone interference effect is attributed to abnormal circuit branching and said to depend on the exchange design. No established cause is supplied.
Why this remains unresolved or set aside
There are no circuit diagrams, signal traces or independent service records linking the interruptions to the proposed explanation. A difference between exchange types does not by itself identify a mechanism.
What would clarify it
Review any existing equipment documentation and incident records, separating observed symptoms from proposed causes. Compare ordinary explanations using documented evidence; no interference method or operational test is provided.
This item remains listed outside the current chapter programme.
Could a docking structure disappear and form again?
The proposal describes a docking structure that would dissolve or disappear and then form again under central control. It supplies no demonstrated material process.
Why this remains unresolved or set aside
The material inventory, shaping method, energy requirement and restored strength are unspecified. Reforming a shape is different from proving that it can seal, carry loads and survive repeated use.
What would clarify it
Define where the material goes and how the structure would be rebuilt. Seek evidence for shape accuracy, joints, sealing, load capacity and repeated cycles; ordinary local repair does not validate complete reconstruction.
This item remains listed outside the current chapter programme.
Related content: Name the response. Measure its tradeoffs.. Conventional context for evaluating reversible material changes: specify inputs and outputs, recovery time, repeated cycles, defects and energy or mass costs. It does not demonstrate disappearance, reconstruction, docking, sealing or restored load capacity.
Could joining metal preserve its original properties?
A proposed process would join or cut metal by rapidly melting its surface beneath a thin layer of inert gas, such as helium or xenon. It claims to preserve elasticity and prevent branching crystal patterns from forming as the metal cools, but supplies no results.
Why this remains unresolved or set aside
The energy source and melting mechanism are unspecified; flame, electric arc and resistive heating are explicitly excluded. There are no identified alloys, microscope images or mechanical measurements showing that the claimed material properties survive the process.
What would clarify it
Identify the energy input, material and claimed changes, then compare measured before-and-after material properties with established joining processes. This is a review of evidence, not a procedure for making or testing a device.
This item remains listed outside the current chapter programme.
Related content: Joined together. Still the same material?. Explains property-specific evidence and compares a published conventional solid-state joint with base material. It does not validate the unspecified melting process, preserved elasticity or the separate cutting claim.
Can an envelope reveal that it was opened?
A sealed and stitched envelope is proposed to make opening noticeable. This is a physical tamper-evidence idea, not a new scientific principle or a guarantee that interference will be detected.
Why this remains unresolved or set aside
The arrangement and its detection performance are not documented. Ordinary handling could leave damage, while an apparently intact envelope alone cannot prove who sent it, whether its contents are true or whether they stayed confidential.
What would clarify it
Clarify which signs would count as possible opening and define the baseline condition. Assess observed examples against ordinary handling damage and report missed changes as well as false alarms. Keep opening detection separate from sender authentication and confidentiality.
This item remains listed outside the current chapter programme.
Related content: What can an envelope seal tell you?. Discusses tamper evidence and a possible way to measure false alarms and missed changes; this does not establish performance because no detection rate has been measured for the proposal.
What signal could guide a wearable locator?
An ear-worn device is described as guiding a group towards a destination. The account does not identify what signal it detects or how that signal becomes a direction.
Why this remains unresolved or set aside
No transmitter, sensing method, range, accuracy or recorded route establishes the claimed guidance. Distances travelled nearby are not measurements of the device’s detection range.
What would clarify it
Seek an original device description and existing observations that identify the signal, reference location and guidance error. Do not assume radio, satellite navigation or any other sensing method from the wearable form alone.
This item remains listed outside the current chapter programme.
Related content: Locating yourself is different from locating a transmitter. Explains the distinction between position estimates and a signal source; it does not identify the wearable's signal, range, accuracy or guidance method.
What would establish a claimed destructive security feature?
An account says that forcing a packet open destroys part of its contents. This describes a claimed outcome, without explaining the physical cause. A separate account claims that equipment destroys itself if it leaves its operators’ control. Loss of control and forced opening are different stated conditions; no shared mechanism is demonstrated.
Why this remains unresolved or set aside
No material, mechanism, timing or documented before-and-after evidence explains the loss. It is not established whether any separate trigger exists. Loss of contents is a different outcome from making opening visible. The equipment account supplies no verified trigger, timing or event record either.
What would clarify it
Compare observed damage with plausible mechanisms to distinguish measurements from interpretation. No construction method, destructive test or security guarantee follows from this account.
This item remains listed outside the current chapter programme.
Related content: What can an envelope seal tell you?. The seal example distinguishes signs of possible opening from protection of contents. It does not demonstrate the claimed destructive response or the separate loss-of-control feature.
Could a radioactive marker reveal an insect’s migration?
The proposal describes radioactively marked insects being detected as they migrate. A marker would need to produce a distinguishable detector signal; the claimed ability to locate them anywhere is not demonstrated.
Why this remains unresolved or set aside
The isotope, signal strength, detector response, background, range and observed tracks are missing. No measurements establish individual identification or detection regardless of distance and surroundings.
What would clarify it
Seek existing study records describing what was marked, what was measured and how detections were distinguished from background. Assess documented tracking limits without assuming unlimited range; no marking or radiological procedure is provided.
This item remains listed outside the current chapter programme.
Related content: Seeing more does not always mean more animals. Explains how repeated wildlife detections differ from true presence; it is not radiotracer physics or individual migration tracking and establishes no unlimited detection range.
What would establish a new nuclear-energy process?
Two separate routes are proposed: obtaining useful energy from nuclear fusion, and converting an intense neutron beam into an energy output. Neither route is described as a reproducible working system.
Why this remains unresolved or set aside
The fusion proposal lacks identified fuels, reaction conditions and a complete energy budget. The neutron-beam proposal lacks the beam’s source-energy requirement and a specified conversion process. No measured net energy gain, efficiency or cleanliness is established; the two routes must not be treated as one demonstrated apparatus.
What would clarify it
Seek existing technical descriptions and energy measurements for each route separately. Include the energy needed to supply and operate the system, its useful output and losses before interpreting any gain claim. No reactor design or operating procedure is provided.
This item remains listed outside the current chapter programme.
Related content: Starting a process is not supplying all its energy. Shows why an energy claim needs a complete input-and-output budget; it models neither fusion nor neutron-beam conversion and establishes no net energy output or device.
A hypothetical device for treating leukemia
An illustrative scenario imagines a device that could treat any form of leukemia. The account says such equipment could be constructed while also saying that the usual treatment would take other routes. It does not establish that this device exists.
Why this remains unresolved or set aside
No mechanism, constructed prototype, patient evidence, clinical endpoint or measured outcome is supplied. A hypothetical promise of treating an existing disease is different from preventing cancer and cannot establish effectiveness or suitability for any patient.
What would clarify it
Keep this as an unverified hypothetical claim. Review any independently available device description and clinical evidence if they emerge; no treatment recommendation, clinical protocol or device-development procedure follows from the scenario.
This item remains listed outside the current chapter programme.
What would make a neutrino communication link work?
The proposal names neutrinos as carriers of information. Specifying a carrier is only one part of a link: a transmitter must encode a message and a receiver must detect and decode it.
Why this remains unresolved or set aside
No beam characteristics, detector, coding method, measured received signal, data rate or error results establish the proposed apparatus. Demonstrations using other equipment would not validate this unspecified system.
What would clarify it
Seek existing technical descriptions and recorded transmission results, keeping the proposed system separate from documented neutrino experiments. Assess the complete transmitter, path and receiver before interpreting a performance claim.
This item remains listed outside the current chapter programme.
Related content: Could a message pass through the ground?. Links to a published 2012 neutrino communication experiment; its demonstrated research link does not validate the unspecified proposal.
How could an image form on a textile?
Two separate explanations are described: chemical staining that would form an original image, and copying an image using a shaped metal form with separately controlled heating, cooling and later finishing. Another account attributes the original image to plant-based substances applied to a body. None of these explanations is established by supplied measurements.
Why this remains unresolved or set aside
There are no specimens, original image data, measured temperature maps or repeatable results linking either process to the image in question. The stated temperatures lack an explicit scale, and the plant-based explanation supplies no formulation or exposure conditions. The accounts also leave an object-identity conflict unresolved: one claims later replacements, while another treats the surviving textile as the original. This is separate from how an image could form.
What would clarify it
Review existing material analyses and records of the textile’s identity and custody, keeping the proposed original staining and later copying processes separate. A possible image-making process would not establish the history of a particular object. Plotting image brightness as height is not independent evidence of physical depth.
This item remains listed outside the current chapter programme.
Related content: Brightness drawn as height does not prove physical depth. Shows why a brightness-to-height visualization is not proof of depth; it does not explain textile image formation, authenticate a textile or support either proposed image history.
An unsupported claim of bodily transfer
Accounts link an emotional state and an alleged change in a specially structured brain to bodily disappearance. They restrict the claim to unusual biology and explicitly rule it out for ordinary humans. A later account revises when the alleged event occurred without independently establishing it or specifying the proposed brain trigger.
Why this remains unresolved or set aside
No defined trigger, physical model, independent observation or measurement of the body and its claimed destination supports the accounts. Wave and porous-material analogies do not supply a transfer mechanism. A revised sequence of events and an unverified witness estimate are not independent corroboration or evidence of a travel capability or medical effect.
What would clarify it
Keep this claim set aside because no independently assessable observations are available. No practical application, prototype or intervention in people is proposed. Reconsider its evidential status only if independently assessable observations become available.
This item remains listed outside the current chapter programme.
Could prenatal care remove every developmental risk?
A claim combines control of the developing child’s genome with support during pregnancy to prevent all developmental malformations and pathological risks to the mother. No measured outcomes establish this universal prevention claim.
Why this remains unresolved or set aside
The intervention, affected conditions, population and assessment methods are unspecified. There are no comparisons or follow-up results showing that every claimed risk is prevented. External gestational support and preventing one particular disease would not establish this broader capability.
What would clarify it
Review any existing descriptions and outcome records, separating maternal health from development of the child. Define each claimed benefit and look for independently assessed results and remaining risks. This entry provides no reproductive procedure or clinical recommendation.
This item remains listed outside the current chapter programme.
What does making a DNA sequence establish?
An account claims that long human gene or nucleotide sequences have been synthesized for biological studies, while discussing a complete human organism hypothetically. A later account claims the broader capability to synthesize a genome, but supplies no completed example.
Why this remains unresolved or set aside
No sequence, length, assembly-verification record or complete-genome result is supplied. Making a DNA sequence, assembling a complete genome, modifying its functions and establishing development of an organism are different claims; evidence for one would not establish the others.
What would clarify it
Seek existing sequence and verification records and identify precisely what material was reportedly made. Keep the asserted sequence work, the broader genome-synthesis capability and the hypothetical whole-organism outcome separate. No biological construction or reproductive procedure is proposed.
This item remains listed outside the current chapter programme.
Related content: A DNA sequence is not the whole story.. Distinguishes sequence agreement, assembly scope, functional evidence and observed outcomes. It does not establish physical genome synthesis, validate the claims, or supply a biological construction or reproductive procedure.
Could electrical differences in the ground supply useful power?
Surface metal conductors and buried metal plates are said to collect energy from electrical potentials in the ground. This differs from the separate proposal to obtain energy using coils and a planetary magnetic field.
Why this remains unresolved or set aside
No measured voltage, current, load or delivered power is supplied. The circuit and energy source are not explained. A voltage difference alone would not establish sustained useful power or an energy advantage.
What would clarify it
Review existing circuit descriptions and measurements, identifying where the energy comes from and what power reaches a specified load over time. Keep electrical-potential collection separate from magnetic-field claims; no installation procedure or performance guarantee is provided.
This item remains listed outside the current chapter programme.
Related content: A generator transfers mechanical energy. Explains induced voltage, current under load and input-power accounting in a hypothetical mechanical generator; it does not identify or test the claimed ground-potential source or circuit.
What would intentional genome changes actually establish?
Proposals describe changing genomes to enable stable offspring between hypothetical incompatible groups, deliberately modifying an organism’s own genome, and producing organisms with more complex brains. These are separate proposed outcomes; none is demonstrated in the supplied accounts. Further accounts propose deliberate genetic changes affecting behavior, describe a particular reproductive experiment as biologically incompatible, and claim broad control of cancer, heart disease and infectious agents. The passages do not establish a contradiction or successful capability.
Why this remains unresolved or set aside
No target changes, verified genome records or measured developmental or cognitive outcomes are supplied. The compatibility proposal is conditional and expressly restricted. More complex brain structure would not by itself establish improved intelligence or consciousness. Related entries 010 and 011 separately record unsupported pathogen/immune and cancer/DNA promises; the added heart-disease-control claim is not a clinical result. Another account rejects near-term spontaneous genome change while describing distant controlled genetic change said to affect behavior. These distinct assertions provide no methods or outcomes and do not establish a contradiction or a working capability.
What would clarify it
Review existing descriptions and independently assessed records to identify exactly what was changed and what outcome was measured. Distinguish genome synthesis from genome modification, and structural claims from functional results. No reproductive procedure, intervention in people or clinical application is proposed.
This item remains listed outside the current chapter programme.
Related content: Sequence, function and outcome are different evidence questions. Context only: explains why sequence information, physical synthesis, biological function and observed outcomes need separate evidence. It does not demonstrate genome modification, reproductive compatibility, changes in intelligence or behavior, or disease control. This claim remains insufficiently specified.
Could a porous block store liquid?
A proposal names porous blocks as a way to store liquids. The intended function is to hold a liquid within a solid block, but no particular liquid, material or working example is identified.
Why this remains unresolved or set aside
The account supplies no pore structure, retention mechanism, capacity, leakage measurements or way to recover the liquid. It does not establish an advantage over an ordinary container, and it does not connect the blocks to solar or thermal storage.
What would clarify it
Look for an existing material specification and measurements of how much liquid is retained, how much leaks, how much can be recovered and whether the material remains compatible with the liquid. A possible application would be holding and later releasing a specified liquid, conditional on those results; no performance benefit is demonstrated.
This item remains listed outside the current chapter programme.

Could an antimatter energy system deliver useful power?
A proposal describes storing antimatter in a vacuum, suspending it by an unspecified gravitational mechanism, then combining it gradually with ordinary matter and collecting the released energy. The intended application is a power source; no working system is established.
Why this remains unresolved or set aside
No storage apparatus, production requirements, conversion efficiency, measured output or complete energy balance is supplied. The proposed suspension method is not demonstrated. Describing energy release does not establish that a complete system produces more usable energy than it consumes.
What would clarify it
Look for existing apparatus specifications and independently assessable energy measurements, including the cost of producing and maintaining the stored material. Any future power application remains conditional on those missing results; the account provides no construction method or demonstrated advantage.
This item remains listed outside the current chapter programme.
Related content: Starting a process is not supplying all its energy. Provides a general energy-boundary example; it does not model antimatter production, storage, conversion or net-power output.
How long could a sealed refuge support its occupants?
A proposal describes a stationary underground refuge that supplies oxygen, water, food and energy while the outside environment is contaminated. It mentions an aftermath lasting about 500 days; that is a scenario duration, not a measured endurance result.
Why this remains unresolved or set aside
No number of occupants, consumption rates, reserves, recycling layout, protective performance or endurance test is supplied. A sealed structure alone does not establish that its occupants can remain supported throughout the stated period.
What would clarify it
The linked study compares an explicitly assigned water-throughput model with NASA-reported ISS water-recovery milestones. The input throughput is pedagogical and excludes air, oxygen, food, energy, water quality, spare parts and failures. To assess the proposed refuge scenario, specify occupants and every resource budget, test integrated systems and backups, and demonstrate health and endurance under defined conditions.

Could a body signal control typing?
An account describes a modified typewriter that supposedly turns changes in an unspecified physiological signal into typing commands. Its possible application would be entering text through a measured body signal rather than pressing ordinary keys.
Why this remains unresolved or set aside
The signal, sensor and decoding rule are not identified. No typing accuracy, speed, delay, calibration record or demonstration is supplied. The description does not establish whether the signal comes from brain activity, muscles or another source.
What would clarify it
Identify the measured signal and intended commands in existing documentation, then seek independent records of correct characters, errors and response time. Accessible text entry is one possible future application to investigate; the account neither specifies that purpose nor demonstrates the device’s capability.
This item remains listed outside the current chapter programme.
Related content: A brain recording is not a transcript of thought. Summarizes a bounded EEG classification example and its limits; it does not establish the proposed physiological typewriter signal, sensor, mapping, typing performance or accessibility.
What would demonstrate repair of injured brain tissue?
An account claims that embryonic tissue transplantation and surgery restored a person after an alleged brain injury. The intended outcome is recovery of function. A separate claim about altering memory does not establish that tissue repair occurred.
Why this remains unresolved or set aside
No clinical record, identified tissue, evidence of tissue survival or integration, independent functional assessment or follow-up is supplied. Neither the alleged injury mechanism nor the claimed recovery is established by the account.
What would clarify it
Assess any existing independently reviewed records by separating the injury, tissue changes, functional outcome and follow-up. This entry preserves an unverified repair claim; it supplies no treatment recommendation or procedure, and does not establish a present or future clinical benefit.
This item remains listed outside the current chapter programme.
What would a miniature gas chromatograph need to show?
An account describes a small gas chromatograph: an instrument intended to separate a sample into components for analysis. It attributes the compact design to miniaturization and machining using ordinary materials and some conventional parts. The described unit is defective.
Why this remains unresolved or set aside
No dimensions, sample-handling system, separation column, detector specification, measurement trace or repeatability data is supplied. Compact size and a defective unit do not establish analytical performance, novelty or an advantage over existing instruments.
What would clarify it
Look for existing specifications and measurement traces from known samples, including how well nearby components are separated and how repeatable the results are. A possible application is chemical analysis with a compact instrument; portability, accuracy and field usefulness remain unestablished.
This item remains listed outside the current chapter programme.
Related content: Let the ingredients arrive at different times.. Explains chromatographic peak overlap using assigned Gaussian curves and explicit width conventions. It does not identify chemicals, recover the proposed instrument, or demonstrate miniaturized hardware performance.
When does a mathematical shortcut work?
An integral transform rewrites a changing quantity in another mathematical form, which can make some equations easier to solve. The reviewed formulas match a conventional method called the Laplace–Carson transform. Their final identity is correct under stated convergence conditions: the accumulated contributions must remain well defined.
Why this remains unresolved or set aside
One mathematical derivation leaves assumptions unstated, and an intermediate step requires a weighting factor that is not defined. A proof can establish the identity under sufficient conditions while an unrestricted version still fails. This conditional result is established mathematics; it does not establish a new technology.
What would clarify it
A teaching example could compare two ways of calculating the response of a simple cooling or control model. This illustrates the conventional transform method, not a device supplied by the sheet. Check the assumptions separately: an ordinary cooling curve that starts above zero does not satisfy the weighted-integral condition at the starting point. Use an explicitly admissible mathematical example to demonstrate the final identity, and compare any prediction about a real object with measurements before claiming practical accuracy.
This item remains listed outside the current chapter programme.
Related content: A study of the Laplace–Carson transform. Shows a conditional proof using a conventional transform identity; the historical priority of the formula remains unresolved and the mathematics is not presented as novel.
Could a magnetic reading tell similar-looking objects apart?
An account claims that magnetic measurements made from orbit could distinguish physical objects from visually similar imitations. Appearance and a magnetic reading are different kinds of information, but the account does not demonstrate that the proposed distinction can be measured from space.
Why this remains unresolved or set aside
The account supplies no orbital height, expected field strength, background measurements, sensor noise, spatial resolution or independent classification results. Detecting a magnetic change would not by itself identify its cause. No demonstrated discrimination capability follows from the description.
What would clarify it
First seek existing measurements and an explicit comparison of signal, background and uncertainty. A civilian teaching example could compare two similar-looking sample objects with different measured magnetic responses. That would illustrate why appearance is not the whole story; it would not establish that those objects could be distinguished from orbit.
This item remains listed outside the current chapter programme.
Related content: One reading. More than one explanation.. Illustrates inverse-cube scaling and a nonunique single axial reading in an ideal classroom dipole model. It supplies no measured object classification, sensor detection limit or orbital discrimination capability.
Could feelings change how we process information?
An account proposes a feedback loop in which cognitive ability increases sensitivity and sensitivity improves the information a person takes in. The terms are not defined well enough to tell whether they refer to emotion, perception, attention or performance on a particular task.
Why this remains unresolved or set aside
No defined task, participant group, measurement, comparison or causal evidence is supplied. The proposed anatomical explanation is not established by the account. An association between two scores would not prove that one causes the other, or that either measures general intelligence.
What would clarify it
Separate the broad claim into clearly measured questions and review relevant independent evidence. One editorial teaching possibility is to compare performance on a learning task under different forms of feedback, while accounting for prior knowledge and other differences. This is a possible research question, not a demonstrated benefit, a clinical assessment or evidence for the proposed anatomical mechanism.
This item remains listed outside the current chapter programme.
Related content: Why an association does not establish a cause. Uses assigned probabilities to show how mixing two contexts can create an association between otherwise independent findings. It provides no observations about feelings, cognitive performance or general intelligence, and does not test the proposed feedback loop or anatomical explanation.
What makes a reference point useful for measurement?
An account describes small pieces said to be radioactive, placed as reference or control points for unspecified measurements. Their intended role is to provide a reference, but the account does not establish what was measured or how the pieces were detected.
Why this remains unresolved or set aside
No identified material, measured emission, detector, reference value, geometry, uncertainty or measurement results are supplied. The description does not establish whether the pieces were spatial markers, instrument checks or something else. A claim of radioactivity alone does not establish a calibrated reference.
What would clarify it
Review existing documentation for the measured quantity, detection method and independently recorded results. A separate civilian teaching example could use ordinary visible markers to show how known reference points help compare positions in photographs. That nonradioactive example would explain the role of a reference; it would not validate the account or its proposed material.
This item remains listed outside the current chapter programme.
Related content: A conversion is not a calibration. Explains reference measurements and calibration uncertainty; its teaching example does not establish the material, radioactivity, detection, geometry or role of the proposed reference points.
Detecting cosmic neutrinos through secondary particles
A proposed method would detect high-energy neutrinos by observing muons produced in their interactions. No detector design, exposure or measurement is specified.
Why this remains unresolved or set aside
The detector medium, geometry, energy response, efficiency, exposure and background selection are missing. The account's attribution to nuclear synthesis in radio stars is not established by the available description. No source-specific sensitivity, astronomical identification, originality or historical priority can be inferred.
What would clarify it
The linked Earth-science chapter explains IceCube’s secondary-particle method and one published NGC 1068 analysis. This comparison teaches the general detection principle only. A useful detector design would need to define the medium, geometry, exposure, signal selection, background rejection and uncertainty.
Read the related chapter: Cosmic neutrinos and how detectors infer them
Established scientific comparison: IceCube: how neutrino detection works. This does not validate the proposed method.
When decoding needs several pieces of information
A proposed multi-step code combines an incomplete symbol table, words checked against a reference text and a follow-up message. The decoding description also refers to recipient-specific information. The table, reference text and complete decoding rules are unspecified.
Why this remains unresolved or set aside
The available description does not establish separate private shares, a precise mathematical dependency, confidentiality or resistance to altered messages. Checking transcription, identifying a sender and restricting access are separate goals. An incomplete codebook is not proof of a secure secret-sharing scheme, and the stated warning categories do not establish predictive ability.
What would clarify it
Educational takeaway: distinguish missing information from protection against guessing, copying or changing a message, and distinguish transcription checks from sender verification. A future teaching puzzle could use a fully disclosed, benign synthetic message. Any modern cryptographic comparison should be treated as a separate design, not as a demonstrated secure protocol.
This item remains listed outside the current chapter programme.

HOW TO READ THE LABELS
What is known.
What is still needed.
Needs deeper review: a useful scientific question or application remains, but its specific performance, assumptions or supporting evidence needs closer examination.
Insufficient information: essential details such as a mechanism, measurable outcome, parameters or observations are missing. A faithful evaluation cannot yet be made.
Not pursued: the proposal is retained as an editorial entry because its scope, basis or proposed intervention does not justify development as an improvement project. This is not an invitation to carry out the intervention.
Unclassified: the available record does not yet support a reliable assignment. A zero count means no record currently needs this holding category; it is not proof that every question is resolved.
An idea can remain set aside while its underlying scientific question appears in a chapter. Evidence status and chapter inclusion are separate decisions. These are editorial evidence assessments, not peer-review decisions or probability scores. Each entry states the next information needed, or explains why no development step is appropriate. There are no invented experimental results in this register.
