Medical Xpress / Orchestrated multi-agent AI systems outperform single agents in health care
As artificial intelligence (AI) becomes more common in health care, from managing records to assisting with medication decisions, researchers at the Icahn School of Medicine at Mount Sinai are asking an important question: ...
Tech Xplore / AI is homogenizing human expression and thought, computer scientists and psychologists say
AI chatbots are standardizing how people speak, write, and think. If this homogenization continues unchecked, it risks reducing humanity's collective wisdom and ability to adapt, computer scientists and psychologists argue ...
Medical Xpress / Prior authorization may hinder access to lifesaving heart failure medications
Prior authorization, a process that requires physicians to obtain approval from health care insurers before certain treatments are covered, may keep patients from filling prescriptions for two critical heart failure drugs, ...
Phys.org / Ancient DNA reveals Ice Age mammals thrived after volcanic eruption
For the first time, scientists have used DNA preserved in ancient sediments to examine how a major natural disaster affected animal populations. A new study of a catastrophic volcanic eruption during the Ice Age has found ...
Tech Xplore / Brain-inspired device could lead to faster, more energy-efficient AI hardware
A team led by engineers at the University of California San Diego has developed a new brain-inspired hardware platform that could help computer hardware keep pace with the explosive growth of artificial intelligence. By combining ...
Medical Xpress / Distinct tumor 'neighborhoods' could guide more targeted treatments in aggressive childhood brain cancer
New research published in Nature finds that tumor cells within supratentorial ependymomas (SE)—an aggressive childhood brain cancer—cluster into distinct tumor cell populations. Much like a neighborhood, each cell subtype ...
Phys.org / Microplastic biofilms carry genes that could alter nutrient cycling in estuaries
A study led by William & Mary's Batten School of Coastal & Marine Sciences & VIMS and published in FEMS Microbiology Ecology reveals that microbial communities growing on microplastics in the Chesapeake Bay carry the genetic ...
Phys.org / Solid but fluid: New materials reconfigure their entire crystal structure in response to humidity
Most solid materials we rely on, from steel, to plastics and ceramics, are designed to have specific properties. Whether a material is soft and flexible, or stiff and tough depends on how molecules within the material are ...
Medical Xpress / Seaweed has the potential to create a shield to block norovirus infection
To date, there are no approved vaccines or antiviral treatments for human norovirus, the leading cause of acute gastroenteritis outbreaks worldwide with more than 685 million infections each year. Norovirus is highly contagious ...
Tech Xplore / New model aims to keep remote robotaxi operators alert and ready
So-called "driverless" cars often have human operators remotely controlling the vehicles to help navigate tricky driving situations and avoid accidents. But this setup poses a number of challenges. How do you ensure the operators ...
Medical Xpress / Claims data study ties epilepsy drugs in pregnancy to developmental risks
Findings published by The BMJ reinforce previous research linking use of the antiseizure drug valproate during pregnancy to neurodevelopmental disorders such as ADHD and autism in children, and indicate no substantial risk ...
Medical Xpress / Why multitasking still fails: Study shows brain can't fully do two tasks at once, even with extensive practice
Even with highly extensive training, the human brain is not really capable of performing two tasks simultaneously. Moreover, even the smallest deviations from trained routines can have a significant impact on how quickly ...
