Phys.org / Molecular 'catapult' fires electrons at the limits of physics
Electrons can be "kicked across" solar materials at almost the fastest speed nature allows, scientists have discovered, challenging long-held theories about how solar energy systems work. The finding could help researchers ...
Phys.org / Microbial ancestor of complex life was more sophisticated than previously thought, studies suggest
Our single-celled ancestor lived in a world without plants, animals or oxygen-rich oceans. Yet, this seemingly simple microorganism took the first steps toward complex life. From this ancestor emerged all multicellular (complex) ...
Phys.org / Toward practical laser-driven light sails using photonic crystals
Most space missions rely on chemical rockets for propulsion. Rockets must carry fuel, which increases spacecraft mass and limits their speed and travel distance. For decades, researchers have explored light sails as an alternative. ...
Phys.org / Scientists successfully harvest chickpeas from 'moon dirt'
As the U.S. plans to return to the moon with the upcoming Artemis II mission, a question endures: What will future lunar explorers eat? According to new research from The University of Texas at Austin, the answer might be ...
Phys.org / Toxic evolution: How wasps and frogs mimic pain molecules to deter predators
Certain species of wasps and frogs share a pain and inflammation peptide similar to one found in vertebrates to help defend against predators—a discovery that contributes to a shifting view of how evolution works, say researchers. ...
Phys.org / Why woodpeckers rarely get rattled: Skulls built to control rotation, not cushion blows
Woodpeckers are well known for striking tree trunks with remarkable force and precision. These birds deliver thousands of high-speed impacts per day, generating mechanical loads that would destabilize the skulls of most other ...
Phys.org / This odd little plant could help turbocharge crop yields
An international team of researchers has uncovered a remarkable molecular trick used by a unique group of land plants, one that could eventually be engineered into crops like wheat and rice to dramatically boost how efficiently ...
Phys.org / Missing technosignatures? Turbulent plasma may blur ultra-narrow signals before they leave their home star systems
A new study by researchers at the SETI Institute suggests that stellar "space weather" could make radio signals from extraterrestrial intelligence harder to detect. Stellar activity and plasma turbulence near a transmitting ...
Phys.org / Why Large Hadron Collider predictions can miss the mark, and a new way to fix it
Estimating things that exist is generally easy, but when it comes to estimating things that do not exist, it's more difficult. This is something physicists from Poland and the UK are well aware of. To improve current simulations ...
Phys.org / Plant cell structure could hold key to cancer therapies and improved crops
Can the bend of a banana give us insight into cancer? What does the shape of a rice grain have to do with infertility? The proteins that give plants their shape and structure are also involved in human disease. A team led ...
Phys.org / Electric field tunes vibrations to ease heat transfer
New research from the Department of Energy's Oak Ridge National Laboratory, in collaboration with The Ohio State University and Amphenol Corporation, challenges conventional understanding about controlling heat flow in solid ...
Phys.org / Making mini-lightning in a block of plastic
Lightning formation and the conditions triggering it have long been shrouded in a cloud of mystery, but new research led by Penn State scientists is lifting the fog. Using mathematical calculations, the researchers have discovered ...
