Medical Xpress / Mapping pre-myelinating oligodendrocytes: New mouse line links neuronal activity to cell survival
Nerve fibers in the brain and spinal cord are wrapped in an insulating sheath known as myelin. For a long time, this barrier, which is essentially the brain's white matter, was believed to serve the main function of speeding ...
Phys.org / Physicists bring unruly molecules to the quantum party
Scientists have made leaps and bounds in bending atoms to their will, making them into everything from ultraprecise clocks to bits of quantum data. Translating these quantum technologies from obedient atoms to unruly molecules ...
Phys.org / Hybrid excitons: Combining the best of both worlds
Faster, more efficient, and more versatile—these are the expectations for the technology that will produce our energy and handle information in the future. But how can these expectations be met? A major breakthrough in ...
Phys.org / Overlooked hydrogen emissions are heating Earth and supercharging methane, research finds
Rising global emissions of hydrogen over the past three decades have added to the planet's warming temperatures and amplified the impact of methane, one of the most potent greenhouse gases, according to new research published ...
Phys.org / Italian bears living near villages have evolved to be smaller and less aggressive, finds study
A paper in Molecular Biology and Evolution, reports that Italian bears living in areas with many villages evolved and became smaller and less aggressive.
Phys.org / Prehistoric elephant footprints documented for first time in Murcia's fossil dunes
An international team, involving researchers from the University of Seville, the Andalusian Institute of Earth Sciences in Granada and the University of Huelva, has identified the first fossilized vertebrate footprints from ...
Medical Xpress / What determines the fate of a T cell? Research highlights cellular 'housekeeping' mechanism
When killer T cells of our immune system divide, they normally undergo asymmetric cell division (ACD): Each daughter cell inherits different cellular components, which drive the cells toward divergent fates—one cell becomes ...
Phys.org / One and done is not enough: Study challenges traditional evolutionary research
Every living being must cope with a changing world—summer gives way to winter, one year it floods and the next is a drought. It's obvious that populations of plants and animals must constantly face new challenges, says ...
Phys.org / Shortest light pulse ever created captures ultrafast electron dynamics
Electrons determine everything: how chemical reactions unfold, how materials conduct electricity, how biological molecules transfer energy, and how quantum technologies operate. But electron dynamics happens on attosecond ...
Phys.org / The perfect polymer? Plant-based plastic is fully saltwater degradable and leaves behind zero microplastics
Researchers led by Takuzo Aida at the RIKEN Center for Emergent Matter Science (CEMS) in Japan have one-upped themselves in their quest to solve our microplastic problem.
Phys.org / Beetles block mining of Europe's biggest rare earths deposit
As Europe seeks to curb its dependence on China for rare earths, plans to mine the continent's biggest deposit have hit a roadblock over fears that mining operations could harm endangered beetles, mosses and mushrooms.
Phys.org / Mitochondria migrate toward the cell membrane in response to high glucose levels, study shows
Unlike our organs, cell organelles such as mitochondria are not fixed in place, but when, where, how, and why organelles move remain unclear. Research published in the Biophysical Journal shows that when beta cells—the ...
