Phys.org / Life's earliest proteins may have folded into complex shapes with far fewer amino acids
How did the earliest life on Earth build complex biological machinery with so few tools? A new study explores how the simplest building blocks of proteins—once limited to just half of today's amino acids—could still form ...
Phys.org / Riding the quantum wave: Quasiparticles reveal a magneto-optical transport phenomenon
Excitons are being explored in materials science and information technology as a means of storing light. These luminous quasiparticles move through individual layers of quantum materials and can absorb and emit light with ...
Phys.org / World's largest collection of Olympiad-level math problems now available to everyone
Every year, the countries competing in the International Mathematical Olympiad arrive with a booklet of their best, most original problems. Those booklets get shared among delegations, then quietly disappear. No one had ever ...
Phys.org / Mars rover detects never-before-seen organic compounds in new experiment
NASA's Curiosity Mars rover has uncovered a diverse mix of organic molecules on Mars, including chemicals widely considered building blocks for the origin of life on Earth.
Phys.org / AI model designs new antibiotic for staph infections after exploring 46 billion compounds
Researchers at McMaster University have developed a new generative artificial intelligence (AI) model capable of drastically speeding up drug discovery—and, in early tests, it has already designed a brand-new antibiotic. ...
Medical Xpress / AI squeezes individual breast cells to learn how to spot cancer risk
Researchers at City of Hope, a cancer research and treatment organization, and the University of California, Berkeley, have created a novel microfluidic platform that can assess women's breast cancer risk at the cellular ...
Medical Xpress / Lipoprotein(a) linked to elevated cardiovascular risk despite standard treatment
New data analyzing more than 20,000 patients from three major NIH studies show that elevated Lipoprotein(a) [Lp(a)] is associated with residual cardiovascular risk and warrants aggressive risk reduction. Researchers presented ...
Phys.org / When humidity changes, so do the colors of sweat bees
Nature is a riot of color. In the animal kingdom, many species, from insects to cephalopods, use their permanent color or change it for communication, camouflage, and thermoregulation. While this type of reversible shift ...
Phys.org / Uganda's Python Cave reveals how a Marburg virus outbreak could begin
Marburg virus disease (MVD) is a severe and often fatal hemorrhagic disease in humans caused by the Marburg virus. It is carried by Egyptian fruit bats and can spread to people after exposure in caves or mines where they ...
Phys.org / Archaeological digs in Amazon provide clues about Indigenous inhabitants before colonization
Paving roads in the Amazon rainforest has long brought deforestation that threatens the people who live there. The same roadwork, however, has also allowed archaeologists to get glimpses of the region's past long before Europeans ...
Tech Xplore / Tiny, knotted robots jump, fly and plant seeds
When a knot lets go, it doesn't just fall apart. It snaps. That simple observation led Penn Engineers to rethink what a knot can do. Instead of treating it as something that holds tension, they asked a different question: ...
Medical Xpress / Dopamine deficiency found to drive memory impairment in Alzheimer's disease
Why do memories fade in Alzheimer's disease—and can they be restored? University of California, Irvine researchers have uncovered a key mechanism underlying memory loss, showing for the first time that dopamine dysfunction ...
