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 / 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 / Nuclear war at Ukraine-Russia border could trigger years of global climate disruption and radioactive fallout
Geopolitical tensions in Eastern Europe underscore the urgency of addressing the climate and radiological consequences of a regional nuclear conflict. Even a small-scale nuclear conflict at the Ukraine–Russia border could ...
Phys.org / Giant octopuses may have ruled the oceans 100 million years ago
Today's octopuses are intelligent, remarkably flexible animals that lurk in reefs, hide in crevices, or drift through the deep sea. But new research suggests that their earliest relatives may have played a far more predatory ...
Phys.org / Inside the skull of a Devonian fish from Gondwana, revealed by neutron imaging
Flinders University researchers have taken a revealing look inside the head of one of the first animals to crawl from the water to live on land more than 380 million years ago. Using high-tech neutron imaging, they scanned ...
Phys.org / From the Pampas to Patagonia, DNA reveals South America's human history
A new genetic study shows that cultural diversity in the so-called Southern Cone—the roughly triangular southernmost part of South America—was strongly influenced by extensive human migration. An international research team ...
Phys.org / Scientists discover how the Twelve Apostles were formed—and their real age
Scientists at the University of Melbourne have uncovered for the first time how Australia's iconic Twelve Apostles were formed, finding tectonic plate movements over millions of years lifted and tilted the giant structures ...
Phys.org / New bioreactor turns stem cells into an immune-cell factory, producing 40 million human macrophages per week
Researchers at Hannover Medical School (MHH) have developed a method for the efficient production of human immune cells, such as macrophages, in medium-sized bioreactors. These immune cells can be derived from induced pluripotent ...
Phys.org / Divergent moral values could make groups more accepting of norm-breaking behavior
Individuals in a morally diverse community tend to believe that the community's norms are looser. In turn, norm violations are more accepted, and there is a reduced willingness to police transgressions, according to research ...
Phys.org / DNA damage just got more complicated: A long-missed weak spot emerges when light and oxygen strike
In everyday life, our genetic material is constantly under attack from many factors. Environmental influences such as light, along with internal processes like inflammation, can generate oxidative stress that damages DNA ...
Phys.org / Common soil fungus could cut pesticide use while helping tomatoes grow stronger
Trichoderma species—a common fungus found in soils—have varying abilities to promote tomato plant growth and differentially affect the abundance of certain soil bacteria, according to a study led by researchers at Penn State.
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 ...
