Phys.org / Short-lived optical flare AT2022zod is an unusual tidal disruption event, astronomers find
An international team of astronomers has investigated a short-lived optical flare designated AT2022zod. As a result, they found evidence indicating that this flare is an unusual tidal disruption event. The findings were presented ...
Phys.org / Decoding the chemistry of life: Maximum entropy reveals how mutations alter enzymes and drive drug resistance
For decades, Arieh Warshel, USC Distinguished Professor of Chemistry and a 2013 Nobel laureate, has used computer simulations to understand how enzymes—fundamental to nearly every biological process in living organisms—carry ...
Phys.org / How to watch one of the year's best meteor showers, the Geminids
It's time for one of the strongest meteor showers of the year.
Medical Xpress / Priming for depression in a dimly lit world
St. Hedwig Hospital and Charité–Universitätsmedizin Berlin researchers report that repeated mornings spent under dim indoor light in healthy young adults raised afternoon and evening cortisol and reshaped sleep in ways ...
Phys.org / How oxygen first reached Earth's oceans
For roughly 2 billion years of Earth's early history, the atmosphere contained no oxygen, the essential ingredient required for complex life. Oxygen began building up during the period known as the Great Oxidation Event (GOE), ...
Medical Xpress / New model frames human reinforcement learning in the context of memory and habits
Humans and most other animals are known to be strongly driven by expected rewards or adverse consequences. The process of acquiring new skills or adjusting behaviors in response to positive outcomes is known as reinforcement ...
Tech Xplore / Infant-inspired framework helps robots learn to interact with objects
Over the past decades, roboticists have introduced a wide range of advanced systems that can move around in their surroundings and complete various tasks. Most of these robots can effectively collect images and other data ...
Phys.org / Simplified lab process produces potent nerve-blocking molecules found in shellfish
Chemists have long been fascinated and frustrated by saxitoxin: a molecule that causes temporary paralysis by blocking the electrical signals that nerve cells (neurons) use to activate muscle, and which accumulates in shellfish ...
Medical Xpress / Neutron scattering sheds light on lung injuries linked to vaping
Researchers from the University of Windsor are using neutrons at the Department of Energy's Oak Ridge National Laboratory to better understand symptoms associated with e-cigarette/vaping-associated lung injury (EVALI).
Medical Xpress / Q&A: RSV's hidden toll—adults of all ages may struggle with breathlessness, daily activities for months
Recovering from respiratory syncytial virus often doesn't end when it's time to leave the hospital, even for younger adults.
Medical Xpress / Life-saving frozen blood platelets prove safe to use in critically injured patients
Research has proven frozen blood platelets are safe and effective for use in critically injured patients—a breakthrough dramatically extending their shelf life for transfusions from one week to two years.
Phys.org / 'Monster Stars' from the cosmic dawn: Astronomers find first direct evidence
Using the James Webb Space Telescope, a team of international researchers have discovered chemical fingerprints of gigantic primordial stars that were among the first to form after the Big Bang.
