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.
Medical Xpress / Brain activity reveals the melodies that people imagine
In a study led by Jii Kwon and Chun Kee Chung of Seoul National University, researchers explored whether they could recreate melodies from the brain activity of people who imagined how songs continue after listening to a ...
Phys.org / NASA's Perseverance captures Phobos and Earth
This composite of seven images from the Mastcam-Z instrument aboard NASA's Perseverance Mars rover shows Earth, visible as a small bright dot moving from upper left to lower right, passing behind the Martian moon Phobos on ...
Phys.org / Male sperm whales produce loudest communication sounds ever measured in any mammal
Deep in the world's oceans, large male sperm whales emit slow, low-frequency clicks with the highest source levels of any animal communication sounds. These slow clicks are not the echolocation clicks the whales use to locate ...
Medical Xpress / How oxygen levels synchronize heart muscle and blood vessel development
During development, regional dips in oxygen levels serve as a signal that triggers the coordinated growth of heart muscle and coronary vessels, according to a study led by researchers at Weill Cornell Medicine. The findings, ...
Tech Xplore / Selective microwave heating speeds bamboo-to-hydrogen fuel conversion
Researchers at Kyushu University have shown that microwave (MW) radiation can dramatically speed the conversion of biomass into useful gases by creating localized high-temperature regions on nickel nanoparticles. Using advanced ...
Phys.org / Pluto's hazy atmosphere may be collapsing as it moves farther from the sun
Pluto is on an icy march away from the sun. In 2114, it will turn back, but until then, its elliptical orbit will carry it to colder and darker parts of the outer solar system. This is Pluto's first time entering the outer ...
Phys.org / Good news for our coasts and climate: Mangrove forests are bouncing back
Mangroves are perplexing plants. They breathe through their roots, appear to stand on stilts and grow best in hot, salty seawater drawn in and out by the tide.
Phys.org / Mythical mountain god inspires name for China's first freshwater cave snail
A team of scientists has announced the discovery of Erhaia dijiang, a species of eyeless freshwater cave snail.
Phys.org / New method could sharpen diamond quantum sensors for tracking activity in single cells
A diamond-based quantum sensor inserted into a living cell can provide previously unseen levels of detail about how life works and how diseases form. "Think of it as an EKG for a single cell—a way to capture everything happening ...
Medical Xpress / Three proteins help organs tailor shared circadian clock to their individual needs, mouse study finds
LMU researchers have elucidated how different organs adapt the same clock machinery to regulate their individual needs over the course of a day.
Medical Xpress / Hidden DNA regulators may drive neurodevelopmental disorders by reducing FOXG1 protein
A new study from the laboratory of Gemma Carvill, Ph.D., associate professor in the Ken and Ruth Davee Department of Neurology's Division of Epilepsy and Clinical Neurophysiology, has uncovered variants in noncoding regulatory ...
