Phys.org / Sharks are famous for fearsome teeth, but ocean acidification could make them weaker
Sharks are the most feared predators in the sea, and their survival hinges on fearsome teeth that regrow throughout their lives. But changes in the ocean's chemistry could put those weapons at risk.
Phys.org / Honeycomb lattice sweetens quantum materials development
Researchers at the Department of Energy's Oak Ridge National Laboratory are pioneering the design and synthesis of quantum materials, which are central to discovery science involving synergies with quantum computation. These ...
Phys.org / Understanding the unusual chirality-driven anomalous Hall effect via scattering theory
A new framework for understanding the nonmonotonic temperature dependence and sign reversal of the chirality-related anomalous Hall effect in highly conductive metals has been developed by scientists at Science Tokyo. This ...
Phys.org / How actin wavefronts rescue T cell receptors from endocytosis
Every time our body encounters a new disease-causing agent, a crucial defense system called adaptive immunity comes into play. T cells, the top agents in this system, survey the internal environment of infected cells and ...
Phys.org / Plant diversity shapes chemical communication in ecosystems
Researchers at the Max Planck Institute for Chemical Ecology and the University of Kiel have provided experimental evidence showing that reducing plant species diversity alters plant chemical signals across whole communities ...
Phys.org / Sideways discovery rewrites the rules of antigen presentation
A new discovery about how cells communicate with each other in the body's immune system has revealed deeper insights for an international team of scientists into fundamental immune system function.
Phys.org / When tropical oceans were oxygen oases
Research reveals when and why ancient tropical seas transitioned from oxygen oases to marine dead zones, providing clues to the long-term evolution of oceanic environments.
Phys.org / Exploring mutations that spontaneously switch on a key brain cell receptor
Many people are familiar with histamine, a biological molecule that serves as a key driver of allergic reactions and other immune responses. However, histamine is also a major neurotransmitter in the mammalian brain, regulating ...
Phys.org / Astronomer uses 'China Sky Eye' to reveal binary origin of fast radio bursts
An international team of astronomers, including researchers from the Department of Physics at The University of Hong Kong (HKU), has uncovered the first decisive evidence that at least some fast radio burst (FRB) sources—brief ...
Phys.org / Chiral nanowires can actively change electron spin direction
The phenomenon where electron spins align in a specific direction after passing through chiral materials is a cornerstone for future spin-based electronics. Yet, the precise process behind this effect has remained a mystery—until ...
Phys.org / When employees feel slighted, they work less, research reveals
A missed birthday. A forgotten anniversary. A milestone that goes unnoticed. These small slights from a manager may seem like no big deal, but new research from Wharton reveals that even the mildest of mistreatment at work ...
Phys.org / Biomass-derived furans offer sustainable alternative to petroleum in chemical production
A research project conducted by the Max-Planck-Institut für Kohlenforschung shows how biomass can be used as a raw material for chemical products instead of petroleum. The scientists have published their findings in the ...
