Researchers warn betting on clinical trials could incentivize insider trading and interfere with drug development. But Kalshi and Polymarket say they provide valuable information to patients.

Stress may literally scramble the brain’s internal GPS. Researchers found that cortisol, a hormone released during stress, made people significantly worse at navigating a virtual environment and disrupted the precise activity of grid cells, specialized brain cells that help us un

Atomically thin semiconductors could enable dramatically smaller and more efficient chips, but a stubborn problem at the boundary between materials has limited their performance. Researchers have now engineered that atomic interface to protect electron flow while still allowing e

Frequent cannabis users may wake up with unusually high levels of the stress hormone cortisol, suggesting their daily stress rhythms could be disrupted. Researchers say the finding raises questions about whether using cannabis for stress relief might, over time, interfere with th

Deep underground, bacteria may be capable of doing something remarkable: trapping toxic uranium before it spreads. When researchers fed microbes in uranium-contaminated mine water with glycerol, about 95% of the dissolved uranium disappeared within 130 days. The bacteria helped c

More than 60,000 years ago, humans in southern Africa were engraving ostrich eggshells with intricate geometric patterns that appear far more organized than previously realized. Researchers found recurring grids, parallel lines, right angles, and repeated shapes, suggesting the d

Two security researchers bought cheap domains—including noreply.net and deleteduser.com—and set up email listening services. Hundreds of companies are sending them corporate secrets. Mais do que repetir a manchete, o ponto aqui e entender o que essa mudanca revela e por que ela m

Security researchers say that Kimi K3, an open-weight model from China, wandered off to the internet in an attempt to cheat on a test it was given. Mais do que repetir a manchete, o ponto aqui e entender o que essa mudanca revela e por que ela merece atencao.

Researchers say breakthrough offers hope for new medicines but also raises urgent biosecurity questionsScientists have made the first viruses designed by artificial intelligence in a milestone that raises hopes for new medicines but also concerns over how to ensure the technology

Stanford researchers have shown that instruments primarily used to understand earthquakes can capture key details about hurricanes, helping meteorologists better predict how storms will evolve and intensify. Mais do que repetir a manchete, o ponto aqui e entender o que essa mudan

Researchers from Kiel University and Trier University have shown, for the first time, that a widely used deworming product for grazing animals doesn't just harm individual plants and insects but also alters entire networks of ecological relationships. The active ingredient invest

Researchers from the USC Mark and Mary Stevens Neuroimaging and Informatics Institute (Stevens INI) at the Keck School of Medicine of USC have found that depression is associated with smaller volume in a specific part of the hippocampus, a brain region essential for learning and
