Integrating small-angle neutron scattering with machine learning enhances measurements of complex molecular structures
Small-angle scattering (SAS) is a powerful technique for studying nanoscale samples. So far, however, its use in research has been held back by its inability to operate without some prior knowledge of a sample's chemical composition. Through new rese.....»»
How to make an old antibiotic 100 times more potent
Nathaniel Martin, Professor of biological chemistry, wondered what would happen if you took an antibiotic that has been known for 70 years and tried to improve it with the latest tools of modern chemistry. Turns out it can become up to a hundred time.....»»
Wild plants and crops don"t make great neighbors: Study finds pathogens spill from one population to the other

Microscopic vehicles propelled by swimming green algae could assist biological and environmental research
Researchers have created tiny, vehiclelike structures that can be maneuvered by microscopic algae. The algae are caught in baskets attached to the micromachines, which have been carefully designed to allow them enough room to continue swimming......»»
Novel strategy proposed for selectively targeting G-quadruplex at specific genome loci
DNA G-quadruplexes (G4s) are a type of quadruple helix structure formed by a continuous guanine-rich DNA sequence. Although DNA G4s are thought to be involved in various biological processes, in many cases their causative effects are largely unclear.....»»

June 25 2024 marked a new "first" in the history of spaceflight. China's robotic Chang'e 6 spacecraft delivered samples of rock back to Earth from a huge feature on the moon called the south pole–Aitken basin. After touching down on the moon's "far.....»»
Recovery of unique geological samples sheds light on formation of today"s Antarctic ice sheet
In recent years, global warming has left its mark on the Antarctic ice sheets. The "eternal" ice in Antarctica is melting faster than previously assumed, particularly in West Antarctica more than East Antarctica. The root for this could lie in its fo.....»»
