Tech Xplore / Tandem solar cell sets 25.5% efficiency record with CIGS-perovskite design
A Berlin-based team from HZB and Center for the Science of Materials Berlin (CSMB) at Humboldt-Universität zu Berlin has set a new record for a tandem solar cell. Using a combination of a CIGS semiconductor layer and perovskite, ...
Tech Xplore / Electrochemical research takes major strides towards harvesting a vital battery material
The supply of lithium—the battery material that keeps digital devices humming, EVs racing and renewable energy on the grid—will not meet even half the expected demand by 2040.
Tech Xplore / Why AI fiction still feels flat: New test shows characters lack mystery and complexity
Researchers at the University of North Carolina at Chapel Hill have found that while artificial intelligence can spin increasingly convincing stories, its characters may still lack one of the qualities that make human-written ...
Phys.org / Martian dust storms may generate atmospheric electrical conditions that could impact future missions
A new study by a doctoral researcher at The University of Alabama in Huntsville (UAH), part of The University of Alabama System, suggests global dust storms on Mars may organize the Martian atmosphere into regions favorable ...
Medical Xpress / Fear-learning circuit shows how stress disrupts brain's ability to suppress trauma
Fear is often thought of as a negative emotion but is actually a natural protective response to perceived threats or danger. It helps us survive. When we experience a situation that causes fear, it becomes stored in our brain ...
Medical Xpress / Almost half of dementia cases could be prevented—but change is needed
Nearly half of dementia cases could be prevented by tackling modifiable risk factors such as physical inactivity, smoking, low education or social isolation, but new Curtin University research suggests current public health ...
Phys.org / Mummified dogs reveal Tiwanaku people buried companions beside homes long before they became status symbols
In the arid landscapes of southern Peru, around 1,100 years ago, someone carefully dug a small pit, laid down a woven mat and placed a young dog within as if sleeping, possibly wrapped in twine. Centuries later, the mummified ...
Medical Xpress / Should lowest-risk prostate 'cancer' still be called cancer? How changing the name could save lives
A growing number of prostate cancer experts argue that calling the lowest-risk prostate cancer "cancer" does more harm than good. A new UCLA-led study found removing the cancer label could dramatically reduce overtreatment ...
Tech Xplore / AI changes its behavior around authority... and that could be risky
Artificial intelligence doesn't just learn how humans talk. It may also be learning who gets listened to. A new study from researchers at the University of North Carolina at Chapel Hill found that large language models, the ...
Phys.org / Abundant catalyst converts methane into valuable liquid chemicals
Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory and their collaborators have demonstrated a promising new approach for converting methane—the primary component of natural gas—into liquid ...
Tech Xplore / Data centers may emit 57% more CO₂ than expected in 2025, study finds
Data centers, whose expansion is being fueled dramatically by the artificial intelligence boom, have a far bigger carbon footprint than previously estimated, a study said Tuesday.
Phys.org / Beyond the 24-hour day: How employee biological clocks and beliefs drive workplace cooperation
Employees' biological clocks do more than determine when they reach for coffee; they fundamentally shape how, when and why people help each other at work. A study published in Organizational Behavior and Human Decision Processes ...
