Tech Xplore / Compression technique makes AI models leaner and faster while they're still learning
Training a large artificial intelligence model is expensive, not just in dollars, but in time, energy, and computational resources. Traditionally, obtaining a smaller, faster model either requires training a massive one first ...
Phys.org / Neanderthals in Central Europe hunted pond turtles—not for food, but likely for their shells
Neanderthals hunted European pond turtles (Emys orbicularis) in Central Europe, though probably not for food. The careful cleaning of carapace elements at Neumark-Nord indicates that shells were reused, perhaps as small containers ...
Phys.org / Optical control of nuclear spins in molecules points to new paths for quantum technologies
Researchers at the Karlsruhe Institute of Technology (KIT) have reported important progress in quantum physics and materials science by optically initializing, controlling, and reading out nuclear spin states in a molecular ...
Phys.org / Top takeaways from the Artemis II mission
NASA's Artemis II mission sent four astronauts—three Americans and one Canadian—on the first lunar flyby in more than 50 years.
Phys.org / How Jupiter cultivated more large moons than Saturn
The two largest planets in our solar system, Jupiter and Saturn, also have the largest satellite systems, or the most moons. At present, Jupiter's reported moon count stands at more than 100 moons, and along with its many ...
Phys.org / Deadly heat thresholds have already being crossed in six recent heat waves, study shows
Deadly heat wave events are occurring at temperatures and humidity levels previously thought to be survivable, according to a new paper by a team of international researchers, including from The Australian National University ...
Phys.org / Ancient tectonic processes are the key to locating rare minerals
New research from Adelaide University has revealed that geological processes dating back billions of years are critical to locating the rare earth elements needed for modern technologies and the global clean energy transition. ...
Phys.org / Momentum-engineered photonic states make bulk silicon shine
An international team of researchers, led by scientists from the University of California, Irvine, has demonstrated a fundamentally new way to make silicon emit light—overcoming one of the most persistent limitations in modern ...
Phys.org / Houston, we have a problem ... with the toilet
After a successful trip around the moon, everything has been going smoothly on the Orion spacecraft's journey back to Earth—except for the $23 million toilet, which has gotten clogged.
Medical Xpress / With navigating nematodes, scientists map out how brains implement behaviors
Animal behavior reflects a complex interplay between an animal's brain and its sensory surroundings. Only rarely have scientists been able to discern how actions emerge from this interaction. A new study in Nature Neuroscience ...
Phys.org / Electron–atom scattering encodes the quantum state of electron wave packets
A new analysis reveals what happens when very short or narrow electron beams encounter a particle. The research is published in the New Journal of Physics. Scientists should be able to achieve a new level of control over ...
Phys.org / Hydroxyl radicals in UV-exposed water reveal surprising reaction pathway
How do radicals form in aqueous solutions when exposed to UV light? This question is important for health research and environmental protection. For example, with regard to the overfertilization of water bodies by intensive ...
