Phys.org / New findings on the first steps in protein synthesis
In the earliest phase of creating human proteins, the protein complex NAC performs an essential task by starting the first steps toward folding proteins into their correct three-dimensional structures. An international research ...
Phys.org / Astronomers discover 87 stellar stream candidates in the Milky Way
Stellar streams are trails of stars that astronomers can study to solve mysteries about the history of our Milky Way galaxy and, potentially, the dark matter that helps shape the cosmos despite eluding direct observation. ...
Phys.org / Gran Dolina site at Atapuerca reveals almost exclusive use of local chert 400,000 years ago
A paper published in the journal Quaternary International reveals a distinctive technological behavior at level TD10.2-BB of Gran Dolina (Atapuerca, Burgos), characterized by the almost exclusive use of local chert and linked ...
Phys.org / First quantum oscillations observed in gallium nitride holes
Gallium nitride, a semiconductor that can operate at high voltages, temperatures, and frequencies, has enabled technologies from LED lighting to high-power electronics. Now Cornell researchers have observed a quantum property ...
Phys.org / Drought spurs rise in antibiotic-resistant soil microbes
A new Caltech study indicates that drought increases the abundances of antibiotic-resistant microorganisms in soils, which directly correlates with an increase in antibiotic-resistant infections in hospitals. In other words, ...
Phys.org / Astrophysicists resolve 'negative superhump' conundrum of deep-space binary star systems
New UNLV-led research is helping to unravel clues to a cosmic mystery that has eluded scientists for decades. Cataclysmic variables (CVs) are binary star systems in which primary stars—incredibly dense and compact white ...
Phys.org / A sudden surge in luminosity: Stacked dyes hint at brighter organic semiconductors
In nature, a certain size is often a prerequisite for biomolecules to perform their specific functions. For example, for proteins or DNA to fulfill their vital tasks, they must be folded in a precise manner—and this requires ...
Phys.org / Chaos as a matter of direction: Researchers build layered material where order and disorder coexist
Some materials behave unexpectedly. They crack differently than expected, or react in ways that are hard to explain. The answer often lies in their atomic structure. Is it neatly arranged, as in a crystal, or disordered, ...
Phys.org / Study reshapes understanding of interaction between organelles in animal cells
Findings from a new University of Cincinnati study have reshaped the fundamental understanding of how a certain cell organelle prepares its environment for cellular digestion. The study, led by UC's Jiajie Diao, Ph.D. and ...
Phys.org / Engineered E. coli can monitor arsenic, offering a cheap biosensor
Cornell scientists have engineered E. coli to act as a sensitive biosensor for monitoring environmental arsenic, a toxic pollutant most notably found in rice paddies in Southeast Asia. Their new study provides a proof of ...
Phys.org / One step closer to deciphering TOR, the molecular machinery that makes humans and yeast grow
The name might sound like a Nordic god, but it is actually the molecular machinery that allows many different species to eat and grow: fungi, plants, whales, humans, flies. It is the mighty TOR protein. An expedition to Easter ...
Phys.org / CryoPRISM: A new tool for observing cellular machinery in a more natural environment
The blobfish, once considered the ugliest animal in the world, has since had quite the redemption arc. Years after it was first discovered, scientists realized that the deep-sea creature appeared so unnervingly blobby only ...
