Phys.org / ALMA watches a massive binary assemble in real time
Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have captured one of the most detailed three-dimensional views yet of a massive binary star system while it is still being born. By tracking the motions ...
Phys.org / Physics-based AI unlocks first global predictions of carbon cycling in ocean sediments
Researchers at The University of Manchester have developed a new physics-based artificial intelligence approach that, for the first time, enables accurate global-scale predictions of how dissolved organic carbon moves between ...
Phys.org / AI model decodes cell signaling fingerprints across diverse cell types
As an embryo develops from a small cluster of stem cells, those once "blank slate" cells begin to take on more specialized roles like brain, liver or muscle cells and organize themselves into three-dimensional structures ...
Phys.org / Melting Svalbard glaciers may flush ancient methane from rocks beneath the ice
Meltwater rivers flowing from Svalbard glaciers are carrying ancient methane from rocks beneath the ice into the open air, new research published in Nature Communications shows.
Phys.org / Tiny molecular rings open new ways for designing better medicines
Cyclopropanes are organic chemistry's smallest rings. Three carbon atoms are joined in a triangle, creating a compact and unusually strained structure. Despite—or partly because of—this unusual geometry, cyclopropanes are ...
Phys.org / Worm's radical transformation shows metamorphosis can change the functions of cells
A squishy worm that starts its life as something of a floating head in the Pacific Ocean is changing what scientists know about metamorphosis at the cellular level.
Phys.org / Star-fingered toads use fingertip lobules to detect prey in murky water
Surinam toads (Pipa pipa) are strange, flat frogs with minuscule eyes that live in the murky waters of the Amazon basin and carry their eggs on their backs. The way they catch prey is even weirder. They lie in wait with outstretched ...
Phys.org / A crystalline sponge reveals structures of large 'beyond rule of 5' molecules
Drug discovery has traditionally followed the "rule of 5," which identifies chemical properties generally associated with good absorption of orally administered drugs, including a molecular weight below 500 daltons (Da). ...
Phys.org / Marine heat waves boost coastal CO₂ uptake by 11%, analysis finds
Marine heat waves are a consequence of climate change and are increasingly altering marine and coastal regions worldwide. An international study led by the Helmholtz-Zentrum Hereon now shows that many coastal seas absorb ...
Phys.org / Sea ice creates hidden highways for young Antarctic krill
New research shows that larval Antarctic krill could be carried far from their birthplace by drifting sea ice, linking distant ecosystems in ways conventional models may miss.
Phys.org / Sparse-data method estimates sea surface temperatures 40% more accurately than conventional approach
Researchers have developed a method for extrapolating sea surface temperatures from sparse data that is significantly more accurate than other commonly used computational methods and slightly more accurate than the best-performing ...
Phys.org / Super-resolution imaging reveals that cohesin prevents local mixing of compact, active genome domains
The human genome is about two meters (6.6 feet) long, yet it is folded inside a cell nucleus only about 10 micrometers in diameter. To fit into this tiny space, DNA is wrapped around histone proteins to form nucleosomes, ...
