Phys.org / New findings overturn 100-year-old assumption about common bacteria in the lungs
The human body is teeming with more than 35 trillion bacteria, coexisting in microbiomes inside the gut, mouth, lungs, skin and urogenital tract. While it's now clear these microbes are associated with health and disease, ...
Phys.org / Early settlement dynamics in the Pacific revealed through ancient DNA
New genetic analyses of ancient human skeletons from western Remote Oceania are shedding light on the complex history of settlement in this vast Pacific region over the past 3,000 years. With island nations such as Vanuatu, ...
Phys.org / Engineered microbe speeds CO₂ capture and recovers critical metals
A genetically engineered bacterium can rapidly break down one of Earth's most abundant minerals, opening a promising new pathway for simultaneously removing carbon dioxide from the atmosphere and recovering critical elements ...
Dialog / Bound gravitational waves inspired by photonic systems
When one mentions "waves," we immediately think of a perturbation that propagates. This applies to waves on the shore, sound waves in the air or electromagnetic waves that we use to transmit information via optical fibers. ...
Phys.org / Airborne observatory improves views of solar corona during cloud-covered eclipse
Using unique equipment installed on NASA's WB-57 aircraft flying above heavy clouds off the coast of Iceland, a Southwest Research Institute-led team successfully observed a total solar eclipse on Wednesday. The high-altitude ...
Phys.org / Cell biochemistry beyond membranes: Condensate physics reveals general rules for chemical responses
Basic biology courses teach that cells contain organelles—such as the nucleus, mitochondria and Golgi apparatus—set apart by lipid membranes to get things done. Recent cell biology research has revealed another organizational ...
Phys.org / Controlling the rotation direction of light without complex new materials
A new pathway has opened for controlling the rotation direction of light simply by changing how molecules are arranged, without having to synthesize complex new materials. Circularly polarized light is a special form of light ...
Phys.org / Constipation is common in astronauts—blood tests provide new answers
For astronauts in space, constipation is a well-known problem. But why this happens has long been unclear. Now, a new study from the University of Copenhagen in collaboration with NASA provides an idea of what happens in ...
Phys.org / Sediments off Brazil's northeast coast reveal sudden changes in heat transport in the Atlantic
According to a new study led by researchers from Brazil and Germany, the main system that transports heat from one end of the Atlantic Ocean to the other may undergo sudden changes in intensity driven by climate change similar ...
Phys.org / Europe's mountain summits are warming—vegetation is responding in surprisingly different ways
Decades of climate change have not left Europe's mountain vegetation unscathed. However, the changes observed do not always match expectations. As a new international study by a research team led by researchers from the University ...
Phys.org / Wheat gene behind Hessian fly resistance cloned after 50-year search
Researchers at the University of Maryland and their collaborators have cloned a gene that makes wheat resistant to feeding by Hessian fly larvae and demonstrated its direct interaction with a protein produced by the insect. ...
Phys.org / Tiny satellite will use the dark side of the moon to eavesdrop on whispers from the early universe
A tiny UK-developed satellite, roughly the size of a small carry-on suitcase, could help answer one of the biggest questions in cosmology: What happened during the roughly 150 million years of the cosmic dark ages, before ...
