Phys.org / Hydrous mantle minerals reveal possible source of seismic anisotropy in stagnant slabs
Seismic waves traveling through Earth's interior often propagate at different speeds depending on their direction, a phenomenon known as seismic anisotropy. Such anisotropy is commonly detected beneath subduction zones, particularly ...
Dialog / A new light-based sensor could help make ultrasensitive disease testing more portable
When we think about highly sensitive medical testing, we often imagine a hospital laboratory filled with large instruments, trained technicians, and carefully controlled conditions. This is especially true for optical biosensing, ...
Medical Xpress / Common epilepsy drug disrupts early brain growth in human organoids after 30-day exposure
It is known that the antiepileptic drug valproate increases the risk of developmental disorders in unborn children. A study conducted by the Karlsruhe Institute of Technology (KIT), the Heidelberg Academy of Sciences and ...
Medical Xpress / 3D-printed trays help human gut organoids self-build nerves and mature twice as fast
Thanks to special 3D-printed scaffolding trays designed by experts at Cincinnati Children's, researchers can now produce larger versions of functional human gut organoids twice as fast as previous methods—and these organoids ...
Tech Xplore / Perovskite/silicon tandem solar cells reach 32.89% certified efficiency with peak-selective passivation strategy
A team of Chinese scientists has developed a new passivation strategy that significantly improves both the efficiency and operational stability of perovskite/silicon tandem solar cells. The study has been published in the ...
Phys.org / Coral refuges in Western Australia resist 2025 bleaching through record marine heat
The team of scientists from James Cook University, University of Western Australia and Edith Cowan University surveyed coral reefs in the West Australian Houtman Abrolhos group of islands (HAI), publishing their findings ...
Phys.org / Asexual lizards, virgin births and clones—the all‑female species of the animal kingdom
It may sound too bizarre to be true, but the Amazon molly (Poecilia formosa), a fish that inhabits rivers, lakes, and swamps in Mexico and Texas, exists over much of its range in populations that are 100% female. In 1932, ...
Phys.org / Unusual nonlinear thermoelectric effect appears in chiral tellurium, confirming theoretical predictions
An unusual thermoelectric effect has been observed in the semiconductor tellurium by RIKEN physicists for the first time. This demonstration points to the potential of similar materials to be used in applications such as ...
Phys.org / Television news coverage of climate policy is limited and polarized in the US, study finds
Two-thirds of Americans want action on climate change, but people vastly underestimate public support for climate solutions and policy. Historically, U.S. news outlets overrepresented views on climate change that went against ...
Medical Xpress / Ovarian cancer cells use stress hormone signaling to shut down immune system, research reveals
When activated in ovarian cancer cells, the receptor for the body's primary stress hormone alters the tumor environment in ways that blunt immune response, according to new research led by UT Southwestern Medical Center. ...
Phys.org / Evolutionary arms race stretches hawkmoths and flowers to extremes
Long before his days of research, Christian Couch was just a kid marveling at the butterflies in the Florida Museum of Natural History's Butterfly Rainforest. Years later, after enrolling as an undergraduate student at the ...
Phys.org / Extraterrestrial life may be slipping past space missions, astrobiologists warn
Suppose there are signs of extraterrestrial life and we have not yet been able to detect them. What does that mean? In Nature Astronomy, researchers discuss the consequences of these so-called false-negative results. "We ...
