Phys.org / Why simulating an entire cell cycle took years, multiple GPUs and six days per run
By simulating the life cycle of a minimal bacterial cell—from DNA replication to protein translation to metabolism and cell division—scientists have opened a new frontier of computer vision into the essential processes ...
Phys.org / Camera captures first video of a red fox attacking a wolf pup
We are used to seeing a strict order in nature, with apex predators at the top feeding on those lower down the pecking order. But in video footage from a nature reserve in Italy, we see a red fox turning the tables, attacking ...
Phys.org / Nearby red dwarf star hosts at least four planets—with one in the habitable zone
In 2020, a study confirmed that two planets orbited the nearby red dwarf, GJ 887. Now, astronomers have confirmed the existence of two additional planets orbiting GJ 887 in a new study published in Astronomy and Astrophysics. ...
Phys.org / Ancient parrot DNA reveals sophisticated, long-distance animal trade network pre-dating the Inca Empire
New analysis of ancient parrot DNA has revealed that vibrant Amazonian parrots were transported alive across the Andes to coastal Peru centuries before the Inca Empire, highlighting a sophisticated pre-Inca, long-distance ...
Phys.org / Antarctic waters DNA survey discovers many microbial genes new to science
The Southern Ocean—vast, boundless waters surrounding Antarctica—plays an outsized role in global climate, largely thanks to tiny drifting organisms called plankton that soak up carbon. Reporting in Nature Communications ...
Tech Xplore / Can AI read papers like a scientist? A new benchmark shows where LLMs fail
To stay up to date and work forward in their fields, scientists must have at their fingertips and in their minds thousands of published studies. Large language models (LLMs) show promise as a tool for exploring the vast scientific ...
Phys.org / Gnaw-y by nature: Researchers discover neural circuit that rewards gnawing behavior in rodents
Researchers at the University of Michigan have discovered that the constant gnawing of rodents isn't just a reflex or a consequence of a tough diet. It also triggers a release of dopamine in the brain—which acts as a biochemical ...
Tech Xplore / The AI that taught itself: How AI can learn what it never knew
For years, the guiding assumption of artificial intelligence has been simple: an AI is only as good as the data it has seen. Feed it more, train it longer, and it performs better. Feed it less, and it stumbles. A new study ...
Phys.org / Opening the path to high-efficiency hydrogen production without expensive precious metals
A research team has successfully designed and developed a proprietary non-precious metal oxygen evolution reaction (OER) catalyst featuring a layered structure optimized for anion exchange membrane water electrolysis (AEMWE) ...
Phys.org / A new model defines an upper limit to planetary radiation belt intensity
We all know that stars radiate light and much more. But radiation belts can also surround many other celestial bodies, such as planets. These belts do not generate particles themselves—the belts receive them from nearby ...
Phys.org / Electron microscopy maps protein landscapes that drive photosynthesis
Research led by scientists at Washington State University has revealed insights on how plants form a microscopic landscape of proteins crucial to photosynthesis, the basis of Earth's food and energy chain. The discovery provides ...
Phys.org / Miniature laser technology could bring lab testing into your home
A research team at Chalmers University of Technology, Sweden, has developed new laser technology that could lead to tiny, cost-effective biosensors. The sensors integrate lasers and optics together on a centimeter-sized chip, ...
