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 / 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 / Curved nanographene with five-, six- and seven-membered rings synthesized in two steps
Nanographenes can be considered molecular fragments of graphene, a 2D conductive material in which carbon atoms are connected in a honeycomb pattern. Because their electronic and photophysical properties vary depending on ...
Phys.org / Untangling the meta-biomaterial puzzle one property at a time
From repairing damaged tissues to developing better implants, many medical developments depend on materials that can mimic the complex properties of human tissue. Meta-biomaterials are among the most promising candidates. ...
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 / 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 / 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 / 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 / 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 / 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, ...
Phys.org / New iron-bearing compounds could store water near Earth's core
Geochemical studies of volcanic rocks from Baffin Island, Canada, and Iceland suggest that some of the water dating back to Earth's formation may still be preserved deep within the planet. However, it has remained unclear ...
