Phys.org / Aromatic compounds: A ring made up solely of metal atoms
The term aromaticity is a basic, long-standing concept in chemistry that is well established for ring-shaped carbon compounds. Aromatic rings consisting solely of metal atoms were, however, heretofore unknown.
Phys.org / Fundamental spatial limits of all-optical magnetization switching
Magnetization can be switched with a single laser pulse. However, it is not known whether the underlying microscopic process is scalable to the nanometer length scale, a prerequisite for making this technology competitive ...
Phys.org / Researchers find magnetic excitations can be held together by repulsive interactions
A group of physicists specialized in solid-state physics from the University of Cologne and international collaborators have examined crystals made from the material BaCO2V2O8 in the Cologne laboratory.
Phys.org / Lie-detection AI could provoke people into making careless accusations, researchers warn
Although people lie a lot, they typically refrain from accusing others of lying because of social norms around making false accusations and being polite. But artificial intelligence (AI) could soon shake up the rules.
Phys.org / To protect corals from heat waves, we should help their microbial symbionts evolve heat tolerance, researchers say
Most coral reef restoration efforts involve restocking reefs with nursery-grown corals. However, if these corals are of the same stock as their wild counterparts, they will be equally vulnerable to the heat stress that caused ...
Phys.org / Dunes decoded: A comprehensive and precise mapping for coastal conservation
Coastal dunes are complex and rich areas at the interface between terrestrial and aquatic ecosystems. They are extremely rich in biodiversity and play a crucial role in both environmental and human well-being, such as protecting ...
Phys.org / Researchers find intriguing new tool for tendon healing: Nanoparticles for precision drug delivery
Harnessing nanoparticles to deliver drugs precisely to a surgically repaired tendon is a promising new approach that reduced scar tissue formation and improved mechanical function. Researchers' success in pinpointing a drug ...
Phys.org / Why the harsh Snowball Earth kick-started our earliest multicellular ancestors
For a billion years, single-celled eukaryotes ruled the planet. Then around 700 million years ago during Snowball Earth—a geologic era when glaciers may have stretched as far as the Equator—a new creature burst into existence: ...
Phys.org / How scientists build rotatory machines with molecules
Machines have evolved to meet the demands of daily life and industrial use, with molecular-scale devices often exhibiting improved functionalities and mechanical movements. However, mastering the control of mechanics within ...
Phys.org / Synthetic fuels and chemicals from CO₂: Ten experiments in parallel
If you mix fossil fuel with a little oxygen and add a spark, three things are produced: water, climate-warming carbon dioxide, and lots of energy. This fundamental chemical reaction takes place in every combustion engine, ...
Phys.org / Do vertebrate populations really decline so much? Calculations indicating severe declines might be wrong, says study
A widely-used Living Planet Index (LPI) characterizes the average change in population sizes of vertebrates and is considered one of the main indicators of the state of the planet.
Phys.org / Newly-discovered bacterial regulatory mechanism has implications for antibacterial control measures
Research spearheaded by four biologists within the College of Arts and Sciences at Indiana University Bloomington has uncovered a new regulatory mechanism shared by many bacteria, which may have profound implications for ...
