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 / Climate and competition alone cannot explain Neanderthal extinction, study finds
A new modeling study suggests that greater connectivity between groups may have given Homo sapiens the edge over Neanderthals. Why Neanderthals went extinct and Homo sapiens established a lasting presence in Europe is still ...
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 / Molecular chains unlock atomically precise nanoribbons for next-generation electronics
Scientists have developed a unique way to build electronic components so small they are made from chains of individual molecules—creating a toolbox to help build materials that could power the next generation of technology.
Phys.org / Why groups slowly stop working well together, even when conditions are good
Humans are generally a cooperative bunch and most of us probably like to think of ourselves as reliable team players. Cooperation is useful for all sorts of reasons, from running a business and managing community resources ...
Phys.org / Machine learning helps detect roars from lion collars without recording actual audio
Roaring over long distances is a key behavior of lions. They communicate within prides as well as with other animals using distinct sequences of moans and grunts. Scientists from the GAIA Initiative have now published a machine ...
Phys.org / Scraped from ancient Roman toilets, these crusted remains expose a pathogen found far earlier than expected
Modern analytical tools are no less than a time machine. From their 21st-century labs, researchers can peer into the everyday lives, hygiene, and even the parasites that plagued the people who lived centuries ago. In one ...
Phys.org / What wild honey from the Philippine jungle reveals about biodiversity
In the Philippines, Indigenous communities have been harvesting wild honey for centuries. A new chemical analysis of this honey now provides insights into the biodiversity of the region. "And an additional reason to protect ...
Phys.org / How earthquakes stop: Near-fault records uncover overlooked phase
While analyzing strong-motion data close to fault lines, a group of researchers at Kyoto University noticed something unexpected: a negative phase in the waveforms, a pattern that did not conform to the existing interpretations ...
Phys.org / Quantum chips could scale faster with new spin-qubit readout that reduces sensors and wiring
Quantum computers, devices that process information leveraging quantum mechanical effects, could tackle some tasks that are difficult or impossible to solve using classical computers. These systems represent data as qubits, ...
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 / What's that swirly pattern? It's a moiré, and it has potential power
Just as wave-like patterns can appear on a computer screen when pixels do not align, new research led by Flinders University is investigating atomic-scale "moiré patterns" in the promising field of ferroelectricity. The new ...
