Varna harbor channel saw currents and water levels surge within 10 minutes

Minute-by-minute measurements in a channel linking Varna Lake with the Black Sea captured two episodes of unusually strong oscillations. Current speed and water level changed by as much as 0.8 metres per second and 0.8 metres, respectively, over 10 minutes.

Enriched adolescence protected stressed mice from schizophrenia-like changes

Giving mice a more stimulating environment during adolescence prevented behavioral and cognitive problems caused by early-life stress. The researchers linked the effect to restored CREB-BDNF-TrkB signaling and found reduced TrkB levels in neuron-derived exosomes from people with schizophrenia.

Review links medication-raised blood pressure to better recovery in some stroke patients

A systematic review and meta-analysis examined medication-induced increases in blood pressure during the first 72 hours after certain acute ischemic strokes. Across three studies involving 366 people, those given this treatment were more likely to be functionally independent after 90 days, although the result does not establish that the treatment caused better recovery.

A cuticle-building enzyme made tomato skins weaker and more prone to fungus

Researchers expected an enzyme involved in building tomato fruit cuticles to strengthen the fruit surface. Instead, engineered tomatoes had less cutin and wax, softer cuticles and greater susceptibility to a common fungus.

Smarter nitrogen use could cut air pollution and bring climate benefits

More efficient nitrogen management could improve air quality and reduce premature deaths while providing long-term climate and ecosystem benefits, according to simulations with two global climate models. The researchers also find a modest, temporary climate penalty before lower nitrous oxide emissions produce longer-term benefits.

Permafrost can keep releasing carbon for decades after warming eases

A climate-model study finds that permafrost can continue thawing and releasing carbon for decades after warming begins to decline. The delay in recovery was larger when peak global warming exceeded 2 °C, although the results come from idealized experiments with one Earth system model.

New analysis links combined heart procedures to more rhythm recurrences

This human-focused meta-analysis compared catheter ablation alone with catheter ablation combined with left atrial appendage closure in 3,274 people with atrial fibrillation across 14 studies. The combined approach was associated with more recurrent abnormal heart rhythms and a slightly longer procedure time, while one serious fluid-related complication did not differ significantly between groups. Because the underlying studies were not described in full and randomized trials are still needed, the results are not conclusive.

A portable light-based device screens alcohol and water in commercial samples

A compact near-infrared device uses lead-free perovskite materials to screen alcohol and water content in commercial samples. Its circuit turns optical signals into five visual levels, covering alcohol concentrations of 30–60% and water contents of 45–100%.

Underwater AI detects marine life faster on power-limited vehicles

A lightweight AI system detected marine organisms in degraded underwater images with lower computing demands than YOLOv8m. Tests on a dataset and an embedded computer suggest it could support faster, more energy-efficient monitoring on autonomous underwater vehicles.

Preprint finds the same hidden instruction can steer AI agents differently

A preprint study found that the same hidden instruction could produce very different results in AI agents depending on whether it arrived as tool information or tool output, and what surrounded it. The findings have not been peer reviewed and may change.

Review examines FASD, harmful sexual behaviour and sexual offences

This systematic scoping review examined research on FASD and harmful sexual behaviours or sexual offences. Across 21 included articles, the literature reported links between FASD and these behaviours, but the review also found major gaps and does not establish that FASD causes them.

Predicting which peptides T cells recognize remains difficult for AI

AI tools for predicting T-cell recognition often struggle when the peptide has not appeared in their training data. A study of structure-based classifiers found that extra training objectives can improve predictions for unfamiliar peptides, but the broader generalization problem remains.

Tabletop laser makes tunable X-ray pulses for imaging and spectroscopy

A tabletop laser system produced tunable extreme-ultraviolet and soft-X-ray harmonics for potential use in resonant imaging and spectroscopy. The work could make some experiments less dependent on large free-electron-laser facilities, although the abstract does not report a direct imaging or spectroscopy demonstration.

Tiny pores help organic frameworks turn otherwise lost energy into light

Nanopore confinement enabled delayed fluorescence in crystalline organic frameworks, allowing them to use energy that would otherwise be lost through non-emissive triplet states. The resulting materials formed high-efficiency light-emitting films and were used in solution-processed organic light-emitting diodes, although the abstract does not report detailed performance figures.

Rotating discs helped a solar still make desalinated water for under 11 cents a liter

A solar still fitted with rotating aluminum discs produced 24% more desalinated water than a drum-based still and 310% more than a standard passive still in experiments. Estimated water costs ranged from 8.2 to 10.3 cents per liter, with projected payback periods under seven months.
