Phys.org / What if humans could regrow tissue? New study moves science closer
For centuries, the inability to regrow lost body parts has been considered a defining limitation of humans and other mammals. While animals like salamanders can regenerate entire limbs, humans are left with scar tissue. But ...
Phys.org / 3I/ATLAS contains 30 times more semi-heavy water than comets in our solar system
New observations of the interstellar comet 3I/ATLAS include the first measurement of the abundance of deuterated water relative to ordinary water in an interstellar object. Astronomers using the Atacama Large Millimeter/submillimeter ...
Phys.org / How a sinking lithospheric root raised Mongolia's Hangay Mountains
Central Mongolia's Hangay Mountains rise more than four kilometers above sea level, forming a dramatic dome that shapes the region's climate. But for decades, geologists have been puzzled: What caused this massive mountain ...
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 / 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. ...
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 ...
Phys.org / A huge tectonic boundary shook the ground where dinosaurs once stood
Scientists have discovered a Jurassic tectonic plate boundary that could help to predict what the planet might look like millions of years into the future. Dr. Jordan Phethean, Senior Lecturer in Earth Sciences at the University ...
Phys.org / AI automates quantum dot voltage tuning for scaling up quantum computing
Semiconductor spin qubits are a promising candidate for the building blocks of next-generation quantum computers due to their high potential for integration and compatibility with existing semiconductor technologies. Qubits—like ...
Phys.org / Brazil unearths a bizarre beaked reptile with a trans-Atlantic prehistoric link
Paleontologists from the Federal University of Santa Maria (UFSM) have published a new study in the scientific journal Royal Society Open Science, in which they describe a new species based on a fossil skull approximately ...
Phys.org / Tiny songbird crosses Sahara by flying night after night
Every year a small songbird, no heavier than a letter, crosses the Sahara Desert, the Mediterranean and the Arabian Desert on its migration. New research from Lund University in Sweden now reveals how the tiny bird manages ...
Phys.org / These 'good' viruses hold up a booming industry—AI just found a faster way to track them
Researchers have developed a new methodology that uses artificial intelligence tools to identify and count target viruses more efficiently than previous techniques. The new approach can be used in applications such as pharmaceutical ...
