Phys.org / Why some nitrogen-processing enzymes are more efficient than others
Nitrogen gas is abundant in Earth's atmosphere, but most living organisms can't readily use it. Only a subset of microbes with enzymes known as nitrogenases can break nitrogen gas apart and convert it into ammonia.
Phys.org / Smart sensor identifies present molecules by remembering the past
Most sensors are designed to do only one thing: detect what passes through them. But what if a sensor could do more? To create a new generation of technology, researchers have looked to living systems for inspiration. If ...
Tech Xplore / Existing power grids draw data centers to cities, study finds
When people picture a data center, they often imagine something remote: a huge warehouse humming quietly far from the city. New research from NYU Tandon School of Engineering shows that assumption is largely wrong.
Medical Xpress / Experimental treatment significantly slows progression of a fatal brain disease in women during clinical trial
Researchers at Tel Aviv University have presented new findings indicating that the experimental drug Davunetide may significantly slow the progression of progressive supranuclear palsy (PSP) in women, who exhibited a markedly ...
Phys.org / AI use mirrors student schedules in study of 77,000 online learners
How do students actually use AI learning assistants? A new research paper by IU International University of Applied Sciences provides the first robust answers to this question. For the study "Using AI-based Learning Assistants ...
Medical Xpress / Deadly brain tumors show vulnerability to new sound wave approach
In a promising sign for the potential of focused sound waves to improve care for brain tumors, UVA Health researchers have determined that tumors called gliomas may be even more receptive to targeted drug delivery than normal ...
Phys.org / Pine bark and sponge compounds could counter drug-resistant malaria and babesiosis
As parasites become increasingly resistant to existing drugs, researchers at the University of California, Riverside, are working to develop a new generation of treatments for two serious infectious diseases: malaria and ...
Phys.org / Antibiotic resistance is spreading through South Africa's water systems. This study explains how
Antimicrobial resistance (AMR) is defined as the ability of disease-causing microorganisms to withstand treatments like antibiotics.
Medical Xpress / Ancient mummy DNA provides scientific evidence that colonization brought smallpox to the Americas
Ancient mummy DNA recovered in Chile has yielded the firmest evidence yet that European colonization brought smallpox to the Americas.
Phys.org / Mom or not, caring for babies changes the brain
Freeman Hrabowski Scholar Bianca Jones Marlin studies how caregiving takes shape in the brain and how some biological adaptations are passed to the next generation.
Medical Xpress / Scientists map dormant cancer cells' hideouts, opening new targets for treatment
Researchers at the MRC Laboratory of Medical Sciences (LMS), Imperial College London and UCL Genetics Institute have created a detailed map of cells within breast tumors and identified distinct neighborhoods of proliferating ...
Phys.org / Forever chemicals and pesticides under Trump: what to know
Since returning to power, President Donald Trump's administration has approved five pesticides considered by many to be PFAS "forever chemicals," a class of toxic substances facing bans and increasing restrictions around ...
