Phys.org / Understanding nature's 'dimmer switch': Study sheds new light on how algae regulate photosynthesis with pH
A new joint study from Constructor University and Princeton University in the Journal of the American Chemical Society focuses on PC645, a protein complex that contributes to cryptophyte algae's ability to photosynthesize ...
Phys.org / Uniaxial strain reveals new way to tune electron flow in altermagnet material
Altermagnetism is a new, third type of magnetism of great interest for spin-transport applications like computer memory. If properly harnessed, it could combine the benefits of the two existing types of magnetism, ferromagnetism ...
Phys.org / A magnetic path to lower-power computing
From smartphones to data centers, modern electronics rely on billions of tiny switches that consume electricity every time they turn on or off. As global demand for computing continues to grow, so does the energy required ...
Phys.org / Muon g-2 experiment places new constraints on a forbidden property of muons
A year after its final muon magnetic anomaly announcement, the Muon g-2 collaboration reports a new measurement of a different property of the muon: its electric dipole moment. The work is published on the arXiv preprint ...
Phys.org / Models of glacial collapse in Antarctica improve predictions of sea-level rise
With approximately one-third of the world's population living within a day's walk of a coastline, sea-level rise poses a serious global threat. Every centimeter of sea-level rise could displace 1.5 million people, and current ...
Phys.org / A dying star offers a rare glimpse of how the universe recycles its raw materials
Astronomers have captured an unprecedented image of a cosmic recycling project in progress—fragments of a dying star being busted up, stripped and absorbed into interstellar space.
Phys.org / African grasslands expanded 5 million year earlier than previously thought, molecular fossils suggest
The iconic grassland savannas of Africa are geographically extensive and important for both local fauna and the global climate. But where did they come from, and how will they change in the future? Ongoing warming, rising ...
Phys.org / Severe weather now a key predictor of where bird species occur in North America
Scorching heat waves, severe cold snaps and other extreme weather events are limiting where species can exist—and affecting biodiversity estimates—for more than 500 North American bird species, according to a new, Yale–led ...
Phys.org / Unsupervised free time increases the likelihood that adolescents will engage in violent behavior, 21-country study finds
A study involving more than 58,000 adolescents from 21 countries found that "unstructured free time"—defined as periods without adult supervision or activities guided by educational, cultural or athletic goals—is strongly ...
Phys.org / Europe's worst medieval flood highlights risk of successive extreme events
New research involving the University of Liverpool has provided comprehensive insights into the largest flood event in Europe over the past millennium—the flood traditionally known as "St. Mary Magdalene's Flood" of 1342.
Phys.org / Graphene nanowrinkles could reshape electricity in future ultrathin devices
Rice University researchers have shown that tiny wrinkles in graphene can change the material's electrical properties, providing evidence for flexoelectricity, a phenomenon in which a material generates an electric charge ...
Phys.org / Drug-carrying nanoparticles shrink venous malformations by 70% in mice
Venous malformations are abnormally shaped veins that develop when the cells lining blood vessels grow too fast when they aren't supposed to. Children can be born with them, and as the child grows, the venous malformations ...
