Phys.org / Monkey friendships with dogs, deer and even pigs offer clues to the evolutionary origins of pet-keeping
Why do humans keep pets? A new international study suggests that some of the behavioral foundations of human-animal companionship may have much deeper evolutionary roots than previously thought.
Phys.org / 2D quantum memory device reaches single-electron limit of information storage
Most electronic memory storage devices require the ability to trap large numbers of electrons for each bit of memory. In an ideal world, however, it would take only one electron. This would reduce space requirements and power ...
Phys.org / Bringing complex field physics to the tabletop: A photonic stage for non-Abelian gauge fields
For most theories in physics, the order of operations has little impact on the result. When setting a dial to a certain position, for example, it doesn't matter whether it's turned clockwise or counterclockwise—the result ...
Phys.org / Non-monogamy may reduce jealousy overall, but feeling less desirable can still strain relationships
Comparing yourself with your partner is more common than you'd think. Psychologists even have a term for it: mate value discrepancy (MVD), which is the gap between how attractive, smart or successful each partner feels compared ...
Phys.org / Curiosity Mars rover discovers field of honeycomb textures
As NASA's Curiosity rover recently began climbing a Martian valley nicknamed "Valle Grande," it sent back images that were a familiar sight to mission scientists: honeycomb-like textures called polygonal fractures, each about ...
Phys.org / The oceans near Australia may be the best places to fertilize for removing carbon dioxide
Deploying ocean iron fertilization—a strategy for carbon dioxide capture—in higher latitudes rather than near the equator could reduce environmental impacts while still achieving removal of carbon dioxide from the atmosphere, ...
Phys.org / Rare-earth ions could enable telecom-ready control of interacting qubits
Quantum technologies are devices and systems that exploit the laws of quantum mechanics and could perform tasks that are difficult or impossible to tackle using their classical counterparts. These technologies process and ...
Phys.org / Little red dots may mark temporary black hole phase
Since their discovery by NASA's James Webb Space Telescope in 2022, little red dots (LRDs) have been the subject of great interest to astronomers. Understanding the nature of these extremely distant, compact red sources has ...
Phys.org / Early Cambrian fossil uncovers key buoyancy structure at the dawn of cephalopod evolution
Extant and ancient cephalopods—including octopuses, squids, extinct ammonites, cuttlefish and nautiluses—have all had to solve the problem of buoyancy, whether they have hard external shells or not.
Phys.org / An entire world of fungi nearly a third of a mile underground could affect carbon storage estimates
Hundreds of feet below Earth's surface, rocks and water teem with fungi and support complex ecosystems of tiny organisms, according to a University of Michigan study that finds fungi are far more abundant deep underground ...
Phys.org / A step closer to artificial organs: UV light shapes arteriole-scale hydrogel vessels
The creation of fully artificial organs is a sci-fi dream, and researchers in Japan may have brought it one step closer to reality by developing a new photofabrication technique (i.e., a light-controlled synthetic method) ...
Phys.org / Black hole 'blast' reaches 300,000 light-years
A team of researchers has discovered that winds generated by supermassive black holes are 100 times more powerful than previously thought, carrying energy across distances of approximately 300,000 light-years. The discovery ...
