Tech Xplore / Exposing biases, moods, personalities and abstract concepts hidden in large language models
By now, ChatGPT, Claude, and other large language models have accumulated so much human knowledge that they're far from simple answer-generators; they can also express abstract concepts, such as certain tones, personalities, ...
Tech Xplore / Repairable infrared lens can cut costs and bring thermal imaging to more devices
The days of dropping a thermal imaging camera and replacing an expensive lens are coming to an end with a new repairable lens developed by Flinders University scientists. The high-performance lens for infrared cameras invented ...
Tech Xplore / New polymer alloy could solve energy storage challenge
In the race for lighter, safer and more efficient electronics—from electric vehicles to transcontinental energy grids—one component literally holds the power: the polymer capacitor. Seen in such applications as medical ...
Phys.org / Do animals have a future on Hollywood sets?
There is a long and storied history of nonhuman actors, from Luke, the dog of silent star Roscoe "Fatty" Arbuckle, to the collies cast in the role of Lassie in film and on television. Bart the Bear racked up over 20 film ...
Phys.org / Antarctica sits above Earth's strongest 'gravity hole.' Now we know how it got that way
Gravity feels reliable—stable and consistent enough to count on. But reality is far stranger than our intuition. In truth, the strength of gravity varies over Earth's surface. And it is weakest beneath the frozen continent ...
Medical Xpress / Early periods and changing fertility patterns may influence ovarian cancer risk
Ovarian cancer is still one of the deadliest gynecological cancers affecting women around the world, especially in East Asian countries, where the numbers keep rising year after year. A new nationwide study in South Korea ...
Phys.org / World's smallest QR code, read via electron microscope, earns Guinness recognition
Just how small can a QR code be? Small enough that it can only be recognized with an electron microscope. A research team at TU Wien, working together with the data storage technology company Cerabyte, has now demonstrated ...
Phys.org / Rewriting our understanding of early hominin dispersal from Africa to Eurasia
What if Homo erectus (H. erectus), the direct ancestor of modern humans, arrived in China much earlier than we thought? Research published in Science Advances may rewrite our understanding of early human dispersal in that ...
Phys.org / Solving a longstanding mystery about complex life's origin—oxygen-tolerant Asgard archaea may explain eukaryotes' rise
The most widely accepted scientific explanation for the arrival of all complex life on Earth has had an unsolved mystery at its heart. According to the theory, all plants, animals and fungi, known collectively as eukaryotes, ...
Phys.org / From power grids to epidemics: Study shows how small patterns trigger systemic failures
Why do some systems collapse suddenly after what seems like a minor disturbance? A single transmission line failure can cascade into widespread blackouts. A delayed shipment can ripple through a global supply chain, emptying ...
Medical Xpress / More states allow MAID, but many Americans remain misinformed or unsure
Public misunderstanding about medical aid in dying in the United States falls into two distinct categories—misinformation and uncertainty—and each is driven by different forces, according to Rutgers Health researchers.
Phys.org / A bacterium's built-in compass, explained: Single-cell magnetometry confirms Earth-field alignment
Some bacterial species possess an astonishing ability: They use Earth's magnetic field to orient themselves. To better understand this mechanism, the team led by Argovia-Professor Martino Poggio from the Swiss Nanoscience ...
