Tech Xplore / AI data centers need faster links: A mass-producible optical microchip could help
Researchers at Karlsruhe Institute of Technology (KIT) and École Polytechnique Fédérale de Lausanne (EPFL) present a novel component that enables very fast, economical, and reliable data transmission thanks to an advanced ...
Phys.org / Why a canceled meeting feels so liberating
Unless your employer is Lumon Industries, where the "Severance" workday never ends, a canceled meeting can feel like a gift of limitless time. A Rutgers University study published in the Journal of the Association for Consumer ...
Tech Xplore / Neuro-symbolic AI could slash energy use while dramatically improving performance
Power usage by AI and data center systems in the U.S. is extraordinary by any measure. The International Energy Agency estimates U.S. AI and data centers used about 415 terawatt hours of power in 2024—more than 10% of that ...
Tech Xplore / Sound waves could be used to remotely reprogram material stiffness, from implants to robotic muscles
A team of researchers co-led by the University of California San Diego, University of Michigan, and the French National Center for Scientific Research (CNRS) at Laboratory of Acoustics of Le Mans University has demonstrated ...
Phys.org / Sea turtle shells reveal hidden records of ocean change
Techniques developed to study the distant past—from dating ancient artifacts to reconstructing climate records in ice cores—are now being repurposed to help us better understand the lives of modern sea turtles. Using ...
Phys.org / Challenging a 300-year-old law of friction
Researchers at the University of Konstanz have uncovered a new mechanism of sliding friction: resistance to motion that arises without any mechanical contact, driven purely by collective magnetic dynamics. The study, published ...
Phys.org / ShadowCam search casts doubt on abundant lunar ice
New observations by a team of US astronomers have cast fresh doubt on whether the lunar surface could host abundant water ice. Publishing their results in Science Advances, a team led by Shuai Li at the University of Hawaii ...
Phys.org / Is the biggest march in English history a myth? My research shows King Harold sailed down to the battle of Hastings
In 1066, England was invaded by multiple foreign powers. A northern force led by King Harald Hardrada of Norway advanced on York via the River Humber, while a southern force, led by Duke William of Normandy (later William ...
Phys.org / The discovery of a buried delta on Mars could boost the search for life
There's more evidence that water once flowed on Mars with the discovery of an ancient river delta deep below the surface. NASA's Perseverance rover found it more than 35 meters beneath Jezero Crater using ground-penetrating ...
Phys.org / Children shaped clay 15,000 years ago, long before pottery or farming, archaeologists find
Long before pottery, before agriculture, when the first villages took shape, people in the Levant were already molding clay with their hands, carefully, deliberately, and sometimes playfully. Some of those hands belonged ...
Medical Xpress / Combining small changes to sleep, diet and exercise could be key to reducing heart attack and stroke risk
New research shows that small improvements to sleep, diet quality, and physical activity, made in combination, are associated with a significantly reduced risk of major cardiovascular events such as stroke, heart attacks, ...
Phys.org / Astronomers discover long-period radio transient of unknown origin
Using the Australian SKA Pathfinder (ASKAP), astronomers have discovered a new long-period radio transient source, which received the designation ASKAP J142431.2–612611 (ASKAP J1424 for short). The newfound transient has ...
