Medical Xpress / Curiosity has its own neural signal: Brain separates valuable information from water rewards in mice
Often, humans and other animals seek information that can help them complete tasks and attain desired rewards. In some cases, however, they seek information driven simply by curiosity and a desire to obtain knowledge for ...
Phys.org / Human blood may have helped preserve ancient Chinese rock art for 2,000 years
The Huashan rock art landscape in southern China, close to the border with Vietnam, is a remarkable UNESCO World Heritage site. Thousands of images are painted on river cliffs across more than 80 locations stretching 260 ...
Phys.org / Dice design solves board gaming's most surprisingly complex problem—who goes first?
It took nearly 15 years, researchers around the world and enough computing power to search through a universe of possibilities to answer one question: Who goes first?
Phys.org / A weakening Atlantic Ocean current system could accelerate Earth's warming
A current system in the Atlantic Ocean that shapes regional climates and distributes ocean nutrients also serves as a control knob to help regulate temperatures across the planet, new research has found.
Phys.org / Lake Zurich sees water level hit record low amid drought
Lake Zurich's water level sank to its lowest level in 75 years on Wednesday, official measurements showed, as a drawn-out drought also took a toll on a range of other major Swiss lakes.
Medical Xpress / Cannabis use linked to earlier onset of psychosis
Cannabis users develop psychosis an average of two-and-a-half years earlier than nonusers, a new meta-analysis by UNSW Sydney researchers shows. This earlier onset of psychosis becomes more pronounced with age, stretching ...
Tech Xplore / Workplace AI learns to read more like humans by breaking documents into multiple levels
Modern artificial intelligence (AI) platforms can summarize reports, analyze documents and answer questions in seconds. But when information is spread across dozens of slides, charts and tables, even advanced models can miss ...
Phys.org / Curved surfaces reshape active materials, localizing vibrations near defects
Many materials, both living and engineered, are powered from within. Scientists have thoroughly investigated how such 'active' materials operate, but so far, mostly in circumstances where the curvature of the environment ...
Tech Xplore / Polymer cage extends zinc-iodine battery life beyond 60,000 cycles
While soaring demand for lithium-ion batteries pushes prices higher, Flinders University experts are making headway in developing a safe, more sustainable aqueous zinc-iodine rechargeable battery. In their latest study, published ...
Phys.org / Climate doom may discourage climate action, but there's a way to counter it
Every summer is getting hotter. Wildfires are blazing, and the worst is yet to come. There's nothing to be done—we're doomed! Sound familiar?
Phys.org / Rare satellite data reveal major limits in flood models
The Kakhovka Dam in southern Ukraine was destroyed on June 6, 2023. The event unleashed a catastrophic flood that forced thousands of residents to evacuate their communities as water levels rose 10 feet (3 meters) above normal.
Phys.org / Most mammal species discovered in the Global South since 1990 end up in Northern collections
According to a study by Brazilian scientists published in the journal npj Biodiversity, most new mammal species described over the past 35 years are housed in institutions in countries of the so-called Global North, even ...
