Tech Xplore / Governments may shape what AI chatbots say by shaping the web they learn from
Ask an AI model the same political question in two different languages, and you may get two very different responses. A new study in Nature suggests one reason why: governments can indirectly influence large language models ...
Phys.org / Spain gears up for August total solar eclipse
Spain, one of the few places in the world where a total solar eclipse will be visible in August, has begun preparations for an event it hopes will shift tourism away from the beaches and toward the countryside.
Science X / Are remoras the ocean's weirdest hitchhikers? These suckerfish invade manta rays in the most intimate of places

Phys.org / Rice plants observed trapping and killing fall armyworm caterpillars
Rice plants and Venus flytraps share something in common that was not scientifically documented until recently. Using a faint smell to lure caterpillars into a trap, rice plants killed early-stage fall armyworm larvae by ...
Phys.org / Engineered exosomes reverse sleep deprivation brain damage in mice
Sleep is a vital physiological process that allows humans and other animals to restore both the mind and body, while also consolidating memories, clearing out toxins and regulating their metabolism. Several past studies showed ...
Phys.org / Heat waves are now everyday disasters. Governments need to do more to protect people
Heat waves are a growing global threat to human health, well-being and livelihoods. Across 12 major European cities during the summer of 2025, a 10-day period of extreme heat led to 2,300 deaths—1,500 of them were attributed ...

Phys.org / Bee magnetism appears far more widespread than expected across 120 species
As married research professors at the University of Tennessee, Knoxville, Dustin Gilbert and Anne Murray often discuss their work once they get home each night. Their fields of study rarely crossover. That changed six years ...
Phys.org / These computer voices sound human enough to mislead, but one layer of speech still breaks the illusion
We are surrounded by computer-generated voices these days, from navigation systems and voice assistants to automated announcements. But how human do these voices actually sound? A recent study by the Max Planck Institute ...
Phys.org / A twinkling pulsar reveals invisible structures in space
The twinkling stars in the night sky are not just beautiful to look at. Their flickering reveals something about the varying temperatures and densities in the layers of Earth's atmosphere, which refract the light as it travels ...
Phys.org / Cut marks on 1.6 million-year-old bones reveal early humans moved prized meat
There is an old adage that goes, "you are what you eat," meaning that the food you consume helps build your body and fuel your mind. The same is true now as it ever was. When it comes to early humans, studying what they ate ...
Phys.org / Stardust trapped in Antarctic ice reveals tens of thousands of years of solar system's past
