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 / New way to harness copper makes antibiotic-resistant bacteria and cancer cells more vulnerable
University of Missouri researchers have discovered a new way to harness one of the body's natural defenses: copper. While copper is essential for life and helps power important biological processes, having too much of it ...
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 / Bear baiting in England became more common following Norman invasion, research reveals
Bear baiting in England became more popular after the Norman Conquest in 1066, new research shows. The study by Cardiff University and the University of Nottingham brings together archaeological analysis of bear bones and ...
Phys.org / Study predicts large disparities in access to food, water and energy in 2050
How will global access to food, water and energy evolve in coming decades? A new study coauthored by MIT researchers suggests the answers could be very different depending on region, resource and income.
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 / Superfluid qubit could help scale up quantum computers
Superfluid helium could offer a new way to tackle one of the biggest challenges in scaling up quantum computers, say researchers from the University of Surrey. The research team has introduced a conceptual design for a new ...
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 / 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 / Rearranged polymer chains create degradable materials with potential for stronger, tougher packaging
What if the key to making stronger, more sustainable plastics isn't changing their ingredients, but rearranging their molecules? Virginia Tech researchers have put that idea to the test, creating degradable polymers with ...
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 / 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 ...
