Phys.org / Fleeting sugar pairs may help curb abnormal cell-growth signals
Acting as armor, a scaffold and a communication platform in one, our cells' plasma membrane lies at the heart of many crucial cellular processes. Traditionally, it has been thought to function through interactions among its ...
Phys.org / The crisis in cosmology continues: Critical problems in a recent defense of cosmic acceleration
Doubts about the standard model of cosmology are deepening after a new study identified fundamental problems in a recent analysis that defended the conventional view that the universe is currently undergoing accelerated expansion ...
Phys.org / Reconstructed Jurassic insect calls evoke a 165-million-year-old forest soundscape
The sights and sounds of the Jurassic era are long gone, and we will never know for sure what that ancient world looked and sounded like. Fossils can offer clues, and reconstructions can give us a sense of the noises some ...
Phys.org / Dogs may use blinking as a subtle social signal
Blinking keeps eyes moist, sweeps away bits of dirt and dust, and helps the brain rest when processing visual information. But in dogs, it may also serve another function as a subtle social signal. That was one of the conclusions ...
Phys.org / Hyperdoped silicon photodiode advances short-wave infrared detection at room temperature
Detecting short-wave infrared (SWIR) light, a region of the electromagnetic spectrum just beyond the light visible to the human eye, could be advantageous for many real-world applications. For instance, it could enable more ...
Phys.org / Thermal anomaly discovered below Mars' south pole
Researchers have discovered a thermal asymmetry deep beneath the surface across Mars' southern hemisphere. Based on gravitational measurements that provide clues to the Red Planet's interior structure, Mars' southern interior ...
Phys.org / Unexpected source of genetic diversity found in human sperm
Scientists have identified an unexpected source of genetic variation in human sperm that occurs earlier in sperm development than previously thought. Published in Nature, researchers at the Wellcome Sanger Institute, the ...
Phys.org / Roman telescope aims to directly image exoplanets 1,000 times fainter than current limits
The Roman Space Telescope is designed to directly image exoplanets using complex optomechanical systems developed by the Max Planck Institute for Astronomy
Phys.org / Utah mountain ranges may store a billion tons of hidden ice
Unlike conventional glaciers, rock glaciers appear as piles of rock that obscure large masses of unaccounted-for ice. Rock glaciers are common in the Wasatch and Uinta ranges, even appearing on the Colorado Plateau in the ...
Phys.org / We discovered rare dinosaur tracks from the Coniacian age near Tumbler Ridge, British Columbia
Imagine the Western Plains of North America, from Texas to Alaska, submerged under a broad, shallow seaway. To the west lay the ancestral Rocky Mountains. To the east were low-lying plains traversed by large, sluggish rivers.
Phys.org / Observing the vibrations of neighboring atoms with an atomic-scale double slit
Efficiently controlling heat generation has become a major challenge as the semiconductors used in smartphones, computers and similar devices have become higher-performing and more miniaturized. The way heat is transmitted ...
Phys.org / Reworked tRNAs enable protein design with up to 34 amino acids
Scientists have been hard at work for more than 20 years to instruct biological systems, such as E. coli cells, to produce proteins they don't naturally produce. Success could mean faster, cheaper, more innovative solutions ...
