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 / 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 / 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 / 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 / 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 ...
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 / 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 / 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 / Heat waves inhibit antibiotic resistance in soils, but at a price
Extreme heat waves disrupt life in soil. Soil bacteria that produce and resist antibiotics switch into survival mode, temporarily reducing the number of resistance genes. At the same time, heat and drought are causing significant ...
Phys.org / Entangled particles revive a 35-year-old test of the Standard Model
Physicists at the BESIII Collaboration have breathed new life into a decades-old test of one of the Standard Model's most important ideas, using a technique that had gone almost untouched by experimenters for 35 years.
