Phys.org / Sugar transporters found to boost aminoglycoside antibiotic entry into bacteria
Aminoglycosides are antibiotics effective against a wide range of bacteria including Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus. Until now however, their mode of entry into bacteria has remained unknown. ...
Phys.org / New theory promises faster, more accurate predictions of chemical reaction energetics
Researchers at the University of Illinois Urbana-Champaign have developed a new theoretical framework that could dramatically reduce the cost and complexity of predicting chemical reaction energetics without sacrificing accuracy. ...
Phys.org / Black student unions are under pressure. Here's what they do and how they help Black students find community
Black student unions have been a vital part of many Black college students' lives for more than 60 years. But since 2024, Black student unions have lost their institutional support, campus space and funding with the rise ...
Phys.org / Severe floods cut global rice yields, threatening food security for billions
Severe flooding has slashed global rice yields in recent decades, threatening food security for billions of people who depend on the grain. The losses amounted to approximately 4.3%, or 18 million tons of rice per year, between ...
Phys.org / Species in crisis: Critically endangered penguins are directly competing with fishing boats
A new study led by the University of St Andrews has found that critically endangered African penguins (Spheniscus demersus) are significantly more likely to forage in the same areas as commercial fishing vessels during years ...
Phys.org / Beyond the usual suspect: Nitrogen feeds algae blooms, researchers find
Nitrogen is a bit of a conundrum. In its gaseous form it's the most abundant element in the atmosphere, but few organisms can readily use it. And while all living organisms contain nitrogen, a new University of Vermont study ...
Medical Xpress / Micropores enhance organ-on-chip models for studying hidden infections
A new study provides a powerful way to study infections in environments that closely mimic human organs. The strategy, tested in a bone-marrow-on-chip model, was developed by researchers from the Barcelona Institute for Global ...
Phys.org / Medieval communities boosted biodiversity around Lake Constance for centuries, study reveals
One of the major realizations of the Anthropocene era has been the importance of biodiversity for the functioning of the Earth system, as well as for human societies.
Phys.org / Wastewater from 47 countries often suppresses resistant bacteria, challenging common assumptions
Municipal wastewater contains a large range of excreted antibiotics and has therefore long been suspected to be a spawning ground for antibiotic-resistant bacteria. Now, a study led by a team from the University of Gothenburg ...
Phys.org / Photo: NASA ER-2 pilot prepares for GEMx flight
NASA ER-2 pilot Kirt Stallings waits inside the transport vehicle moments before boarding the airborne science aircraft at NASA's Armstrong Flight Research Center in Edwards, California, on Thursday, Aug. 21, 2025. Outside ...
Tech Xplore / Some businesses have actually been slow to adopt AI, survey finds
Over the past few years, we have repeatedly been told artificial intelligence (AI) is coming for our jobs.
Phys.org / Light intensity steers molecular assemblies into 1D, 2D or 3D structures
Constructing out-of-equilibrium molecular assemblies that deviate from thermodynamic equilibrium is a central challenge in materials science. While numerous studies have reported the creation of such states using external ...
