A compartmental model built at Lehigh University turns the vagus nerve’s control of digestion into equations that run on a laptop, reproducing how a simulated stomach empties and stalls under stress before any therapy is tested in patients.
An AI model trained on more than 10,000 overnight recordings sorted sleep-study patients into five risk tiers, spotting a doubled five-year mortality gap that the standard apnea severity score missed entirely, in both men and women.
A binary-solvent electrolyte that donates hydrogen bonds only weakly let researchers turn carbon dioxide in simulated flue gas into carbon monoxide at near-total efficiency, even at 1% CO2 with oxygen present, and run the process for over 100 hours.
A new Urban Institute brief finds Black workers concentrated in the jobs AI is least likely to touch, and shows that once education is accounted for, the exposure gap tracks schooling far more than race.
A survey of 426 Nigerian science students found that those handling reagents most often, and eating the fewest fruits and vegetables, reported the most fatigue, headaches and bruising, though no blood test confirmed why.
Two economists reanalysed a public dataset of about 4,000 online test-takers and argue the famous confidence-competence pattern is a statistical artefact. Corrected, it flips: the ablest people looked the most overconfident, not the least.
Physicists in Edinburgh borrowed optimal control theory, the maths of fuel-efficient trajectories, to sculpt magnetic pulses that flip a bit in a few trillionths of a second while spending, in simulation, up to a hundredth of the usual energy.
A review of more than 350 studies finds that low-protein diets extend lifespan in flies and rodents and improve metabolic health in people, though the authors say the right amount likely depends on how active you are.
A survey of more than 500 Japanese gamers found no measurable genre gap by social-withdrawal risk, yet higher-risk players described favouring cooperation, absorbing stories and strategy in their own words.
A method that reads family trees inside 503 living genomes has pinpointed DNA from two archaic human populations that were never sequenced, one shared by all people and one that entered Oceanians through Denisovans.
An unexpectedly free hour feels longer than an hour you planned to have, and across seven experiments that swollen sense of time nudged people into slower choices, longer tasks and, occasionally, a missed deadline.
Pusan National University researchers built a portfolio model that trains on the investment decision instead of the price forecast. A companion review of 164 finance papers found five evaluation biases that quietly inflate reported results.
