Phys.org / Neutrons reveal magnetic signatures of chiral phonons
Physicists in China have uncovered new evidence that chiral phonons and magnons can interact strongly inside magnetic crystals. Using neutron spectroscopy, a team led by Song Bao at Nanjing University mapped magnetic signatures ...
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 / Marine biologists a family history of San Diego's giant kelp over more than four decades
The growth form of giant kelp (Macrocystis pyrifera) is composed of shoots known as stipes instead of branches. From one parent holding fast to the hard bottom might come as many as 150 stipes. Typically, the tips of the ...
Phys.org / New LVK catalog adds 128 gravitational-wave candidates, more than doubling detections
When the densest objects in the universe collide and merge, the violence sets off ripples, in the form of gravitational waves, that reverberate across space and time, over hundreds of millions and even billions of years. ...
Dialog / Chemically tuning nanographene into topological spin chains and why the ends matter
When most people hear "polymer," they think of plastics. In our group, polymerization is a way to line up identical molecules like beads on a string and let quantum mechanics take over. Put magnetic building blocks in a one-dimensional ...
Phys.org / Protecting wildlife from genetic collapse with newly identified 'early warning signals'
A new study reveals that habitat fragmentation can lead to sudden "tipping points" where a species' genetic health unexpectedly collapses after appearing stable for long periods. By merging network theory with population ...
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 / Shrinking the carbon footprint of chemical manufacturing with lasers and solar radiation
Researchers have found a way to use solar energy to power a key chemical reaction that drives many manufacturing industries. This new method can significantly reduce the energy required to run these operations, eliminate ...
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 / How evolution shapes color diversity in coral reef fish
Why does a Caribbean angelfish sometimes resemble its Indo-Pacific cousin, even though they have never lived in the same ocean? Why do coral reefs harbor such a wide range of stripes, spots and patterns? A study conducted ...
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 / 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 ...
