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 / 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 / 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 / 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 / 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 ...
Phys.org / Cells use a little-known molecule to protect themselves from iron overload
Iron is essential. Our cells need it to produce energy, carry oxygen throughout the body and power countless chemical reactions that sustain life. But this metal has a dark side. When too much of it is left free inside cells, ...
Phys.org / Stable RNA elements open new possibilities for mRNA therapeutics
A research team led by Director Kim V. Narry at the Center for RNA Research within the Institute for Basic Science (IBS) has discovered compact viral RNA elements that can make mRNA more stable and increase protein production. ...
Phys.org / US could exhaust domestic phosphorus within 40 years, but waste offers reserves
The United States could exhaust its domestic phosphorus supply within 40 years. Europe, Latin America and Southeast Asia already depend on imports from China and Morocco to meet their needs. Without phosphorus, crops cannot ...
