Phys.org / Surprising diversity found among Europe's last Neanderthals
A new study published in Nature provides the most detailed picture to date of Neanderthal diversity in Western Europe shortly before their extinction.
Phys.org / From virtue to vice: How the morality of popular music lyrics has changed since the 1960s
Popular music may be reflecting a growing culture of vices, according to new research from the Center for Digital Music at Queen Mary University of London. The analysis of musical evolution found that song lyrics have become ...
Phys.org / How long can plants survive on Earth? New model suggests up to 2 billion more years
Vegetarians need not worry yet—plants will be on Earth for a long time to come. But not forever. The sun will ultimately determine the long-term existence of life on Earth. Its total energy output, called luminosity, has ...
Tech Xplore / Brain-inspired AI architecture could compute faster while using far less power
Spiking neural networks (SNNs) are artificial intelligence (AI) models inspired by how biological neurons communicate with each other. While biological neurons exchange information in the form of electrical impulses, SNNs ...
Medical Xpress / Hope for spinal injuries as pigs walk again after experimental gel treatment for severed spinal cords
In humans and other mammals, spinal cord injuries can be devastating, leading to permanent loss of movement, sensation and bladder control. When severed axons (the long fibers that carry messages between nerve cells) cannot ...
Phys.org / Scientists catch classical space-time crystals moving like Majorana quasiparticles
A research team from Hiroshima University, the University of Colorado, and other collaborators have demonstrated that space-time crystals—exotic structures that, under external drive, loop endlessly through both space and ...
Medical Xpress / How high cholesterol dismantles the liver's defenses—and how a new drug could combat it
Cholesterol-related heart disease remains the leading cause of death worldwide, and while doctors have more tools than ever to treat it, many patients still can't achieve safe cholesterol levels or can't tolerate the side ...
Phys.org / By making key signaling molecules called β-arrestins into druggable targets, scientists crack long-standing challenge
To function normally, nearly every cell in the human body relies on G-protein-coupled receptors (GPCRs) to receive and send signals. That's why GPCRs are targeted by roughly one-third of all FDA-approved drugs.
Tech Xplore / OpenAI unveils AI chip Jalapeno
OpenAI on Wednesday unveiled its first custom-designed computer chip, called Jalapeno, built to run ChatGPT and other artificial intelligence products faster and more cheaply.
Tech Xplore / China's EV boom shifts power emissions to poorer cities, limiting climate gains
The carbon-reduction benefits of electric vehicles vary across cities in China, as richer cities can transfer much of their carbon emissions from power generation to less developed cities, burdening them with additional costs, ...
Phys.org / White barn owls may use moonlight to startle prey
White barn owls are effective killing machines. They fly silently through the night air and swoop down on unsuspecting prey with their sharp talons. But they have something you would think goes against being a stealth predator: ...
Phys.org / Axolotl-inspired skin matrix may help heal wounds with less scarring
Researchers in Taiwan have developed a cell-free extracellular matrix material from axolotl skin that helped mouse burn wounds close faster and show signs of reduced fibrotic scarring. The findings suggest that one of nature's ...
