Artificial Intelligence
Research into artificial intelligence and intelligent systems.
Using AI hallucinations to find targets for selective forgetting
Source published
A preprint proposes tracing unsupported AI-generated claims to small groups of internal neurons, then reducing their influence. Benchmark results suggest a better balance between forgetting and useful performance, but the method does not establish permanent deletion.

When does a second AI opinion help retinal screening?
Source published
RetinaGuard combines uncertainty estimates, image-quality checks and selective verification to decide which retinal screening results need review. In a preprint study, verification helped substantially with a weaker primary model but added little once that model’s uncertainty already revealed most of its errors.

Document-parsing leaderboards shift when the scoring rules change
Source published
RankShift compares 16 document-parsing systems and finds that reference formatting and text-matching procedures can substantially reorder their rankings. The preprint argues for reporting ranking robustness alongside headline scores.

Plant Biology
Research into plants, their biology, and their environments.
Maltose boosts hybrid fir embryo yield—but healthy seedlings remain a hurdle
Source published
A preprint reports far more mature embryos from one hybrid fir culture grown with maltose rather than sucrose, alongside earlier accumulation of raffinose. The sugar patterns offer clues to maturation, but do not establish its mechanism or guarantee normal seedling development.

Which parts of wheat growth stay consistent across environments?
Source published
A Bayesian model fitted to simulated wheat growth separated genetic, environmental and interaction effects. Growth timing and curve shape showed relatively little genotype-by-environment interaction, while the final biomass level showed much more. Real-world prediction and breeding benefits remain untested.

Hibiscus study shortlists three cultivars for food research—not a safety endorsement
Source published
A non-peer-reviewed preprint ranks 11 Hibiscus mutabilis cultivars using measurements and expert-selected priorities. Three lead the scoring system, but the results do not establish food safety, nutritional benefits or consumer acceptance, and conflicting descriptions need clarification.

Economics
Research into economic systems, decisions, and policy.
When treatments spill over, an experiment may answer the wrong question
Source published
A statistical preprint distinguishes effects measured under fixed neighborhood conditions from effects averaged over a rollout policy. That choice can determine whether ordinary randomization yields useful evidence or rarely produces the observations researchers need.

- treatment interference

Why governments raise public pay in steps—and cut it during fiscal stress
Source published
An economics preprint uses legal pay decisions from eleven countries to study how inflation, financing costs and fiscal pressure shape public salaries. Its simulations examine judicial review in Portugal and inflation-linked pay in Bangladesh, but the model explains fitted histories better than it forecasts new decisions.

Why sharing resources can benefit the whole but fail the individual
Source published
A theoretical preprint shows how unequal access rules can separate collective benefit from individual incentives. In a two-player resource-allocation game, sharing can produce higher combined payoffs yet give one player a reason to withdraw.

Astrophysics
Research into stars, galaxies, cosmology, planets, and the physics of the universe.
Infrared-bright galaxies occupy the middle ground between steady star formation and starbursts
Source published
ALMA observations of 22 infrared-bright galaxies place the gas-detected objects between ordinary star-forming galaxies and intense starbursts. Their estimated gas-consumption times are hundreds of millions of years. Minor mergers offer one possible explanation, but these observations do not establish an evolutionary pathway.

A solar magnetic-field shortcut has stricter limits than it seems
Source published
Tests with synthetic solar spectra show that the Weak Field Approximation can become unreliable before its commonly used upper limit. Magnetic-field orientation and wavelength selection matter, especially when estimating the component perpendicular to our view.

A Swarm-Based Search for Gravitational-Wave Echoes
Source published
A simulation study tests particle swarm optimization for finding gravitational waves distorted by lensing. The method speeds up parameter estimation, but misses many faint secondary images and remains sensitive to waveform assumptions.

Quantum Physics
Research into quantum mechanics, quantum information, and the quantum behaviour of matter and light.
Why quantum spectral echoes can outlast rapid decoherence
Source published
A theoretical preprint finds that regularly spaced quantum energy levels can retain recurring interference peaks long after decoherence begins. The peaks fade through distinct stages, while faster-changing spectral fluctuations can prolong their survival in the authors’ model.

Tracing photon noise from atomic scattering to quantum algorithms
Source published
A theoretical preprint connects photon–atom interactions to quantum error correction and phase estimation. In an idealized waveguide model, identifying the dominant error suggests a circuit redesign that improves simulated performance.

A common benchmark for simulating quantum computers made of light
Source published
A preprint compares how quickly one GPU can reproduce outcomes from several kinds of photonic quantum device. Its benchmarks measure demonstrated classical capability—not a boundary beyond which quantum advantage is guaranteed.
