Credit: Unsplash A group of scientists from Helmholtz Munich has identified a new use for vitamin K, typically recognized for its part in blood clotting. In its fully reduced configuration, the researchers discovered that vitamin K operates as an anti-oxidant by efficiently inhibiting ferroptotic cell death. Ferroptosis is a natural kind of cell death in...
The United States is returning to the Moon 60 years after JFK's famous speech. On September 12, 1962, United States president John F Kennedy informed the public of his plan to put one man on the Moon by the decade's end. It was the height of the Cold War, and also America needed a huge victory...
Abstract illustration of atoms passing through water and an electrified membrane under a shining sun. Credit: Meenesh Singh A group of scientists led by Meenesh Singh at the College of Illinois Chicago has discovered a way to convert 100% carbon dioxide from the industrial exhaust into ethylene, a fundamental building block for plastic products. Their findings...
Superexchange magnetic interactions in transition-metal oxides. Credit: Proceedings of the National Academy of Sciences (2022). DOI: 10.1073/pnas.2207449119 Today, an international group of scientists led by Séamus Davis, Professor of Physics at the University of Oxford and University Cork, has announced outcomes that reveal the atomic mechanism behind high-temperature superconductors. The searchings for are released in PNAS. Superconductors are...
Credit: Pixabay/CC0 Public Domain The natural world has its own intrinsic electrical grid composed of a world web of tiny bacteria-generated nanowires in the soil and seas that "breathe" by exhaling excess electrons. In a new study, Yale College researchers found that light is an unexpected ally in fostering this electronic activity within biofilm bacteria. Revealing bacteria-produced...
Researchers at Rochester’s Laboratory for Laser Energetics used the same setup at a recent study to create superionic ice, shown here in this artistic rendering. In that instance, the ice was not stable. Credit: Lawrence Livermore National Laboratory illustration / Millot, Coppari, Hamel, Krauss. By subjecting a droplet of water to extreme temperatures similar to those...
Richard Feynman once stated that the double-slit experiment reveals the central challenges of quantum mechanics, putting us ''up against the and peculiarities of nature and paradoxes and mysteries''. Nandini Mukherjee, Richard Zare, and their co-workers at Stanford University, United States, have currently revealed that when helium (He) atoms collide with deuterium molecules (D2) in a quantum...
Credit: Unsplash/CC0 Public Domain For decades, scientists have been seeking a catalyst that dramatically lowers the price of fabricating hydrogen fuel cells. Such an advance could trigger a green power transformation, with everything from laptops to locomotives running on a fuel whose merely byproduct is water. A new study led by the University at Buffalo indicates that...
A new research study examines how getting sufficient sleep affects caloric intake in a real-world setting. Understanding the fundamental causes of obesity and how to stop it is the best means to fight the obesity epidemic, according to Esra Tasali, MD, Director of the UChicago Sleep Center at the University of Chicago Medicine. "The present...
Artist's Impression of a comet passing through our solar system Amateur astronomers may very soon be able to see a comet initially spotted in 2017. Comet C/2017 K2 (PANSTARRS), abridged as K2 for brief, was once the most distant active comet ever before pinpointed, a difference it recently ceded to the mega comet Bernardinelli-Bernstein, found out...
