Phys.org / Climate change could dramatically reduce water flowing from the West's headwaters
The small mountain streams that feed many of the West's rivers may face a much drier future. A new study led by NAU researchers found that groundwater-fed streamflow, known as base flow, has been steadily declining across ...
Phys.org / Supergene solves evolutionary puzzle of mirror-image flowers
The left-right asymmetry of South African butterfly lilies (genus Wachendorfia) has been regarded as a classic evolutionary puzzle for more than a century. Due to the mirror-image arrangement of the floral parts, the plants ...
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 ...
Medical Xpress / Mighty mitochondria: Scientists uncover new role for fighting bacterial infections, including drug-resistant superbugs
Beyond the nucleus, no other organelle in eukaryotic cells captures the public's imagination quite like mitochondria: They are the engines of cellular energy production; they possess their own DNA, and they are passed from ...
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 / Study of 2 million newborns ties skipped vitamin K shot to higher bleeding risk
Newborns receive several routine immunizations shortly after birth. Prophylactic vitamin K is one such recommended shot. It activates several coagulation factors necessary for blood to clot properly, preventing vitamin K ...
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 ...
Phys.org / Diego Rivera claimed his mural Creation was half wax, but chemical forensics says otherwise
Adorning the walls of San Ildefonso College in Mexico City is artist Diego Rivera's masterpiece, rendered in fresco and gold leaf, The Creation, or La Creacioń. It depicts a man standing with his arms outstretched beneath ...
Phys.org / Lichen-like life 600 million years ago may push back origins of fungal-algal partnerships
Two organisms inhabiting a common environment can sometimes mutually influence each other, either benefiting or, in some cases, damaging one another. This mutually beneficial or ambivalent biological relationship is known ...
Phys.org / AI opens new era in cognitive studies of wild primates
Scientists created an AI system that uses facial recognition and real-time touchscreen testing to automate cognitive studies of capuchin monkeys in the wild. The American Journal of Primatology published a proof-of-concept ...
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 ...
