Phys.org / Ocean fronts revealed as key players in Earth's carbon cycle
Narrow bands of ocean covering just over one-third of the world's seas are responsible for absorbing nearly three-quarters of the carbon dioxide that oceans pull from the atmosphere, new research shows. The study, published ...
Phys.org / Twisted oxide crystals show how atomic patterns alone can trap or repel electrons
It has been revealed that simply twisting and stacking two layers of oxide crystals can allow the atomic arrangement itself to control the behavior of electrons. Much like the new patterns that emerge when two meshes are ...
Phys.org / Reconfigurable robotic fish reveals how stiffness and wave propagation shape swimming performance
How can some fish, like tuna, achieve remarkable speed while others, like eels, excel in maneuverability? A research team from Peking University (PKU) has developed a novel robotic platform that sheds new light on this classic ...
Phys.org / A new route to synthesize multiple functionalized carbon nanohoops
The field of nanomaterials is witnessing a transformative shift at the intersection of organic chemistry and molecular engineering. Among the most promising molecular structures are carbon nanohoops, of which [n]cycloparaphenylenes ...
Phys.org / Raman sensors with push-pull alkyne tags amplify weak signals to track cell chemistry
Seeing chemistry unfold inside living cells is one of the biggest challenges of modern bioimaging. Raman microscopy offers a powerful way to meet this challenge by reading the unique vibrational signatures of molecules. However, ...
Phys.org / Net-casting spiders' adjustable silk stiffness point to tunable fiber design
What makes spider silk so extraordinarily strong and elastic at the same time? This was the focus of recent investigations carried out by researchers from the University of Greifswald, the University of Bonn and the Museum ...
Phys.org / How gut bacteria share antibiotic resistance genes and fuel dangerous hospital infections
Researchers from the Yong Loo Lin School of Medicine, National University of Singapore (NUS Medicine), have uncovered how a high-risk class of genetic vectors can efficiently spread antibiotic resistance within the gut, enabling ...
Phys.org / Climate-risk scores guide major decisions, but underlying science is rarely open
When families decide where to buy a home, when cities approve new development, or when governments decide where to invest billions in resilience, they increasingly turn to climate-risk scores for guidance.
Phys.org / Parasite behind toxoplasmosis hides multiple distinct subtypes inside each cyst
A University of California, Riverside team of scientists has found that Toxoplasma gondii, a common parasite affecting up to one-third of the global population, is far more complex than previously believed. The findings, ...
Phys.org / AI model accelerates defect-based material design
Across the physical world, many intricate structures form via symmetry breaking. When a system with inherent symmetry transitions into an ordered state, it can form stable imperfections known as topological defects. Such ...
Phys.org / A specific immune system protein may drive antibiotic tolerance
If you have had strep throat or an ear infection, there's a good chance you received amoxicillin or penicillin to effectively kill the troublesome bacteria. These drugs, which belong to a broad group of antibiotics called ...
Phys.org / How a vital DNA protection protein complex adapts to new threats without compromising its essential functions
In Lewis Carroll's "Through the Looking-Glass," Alice is stuck in a never-ending race with the Red Queen yet never gains a lead. "It takes all the running you can do to keep in the same place," the Queen says. "Though we ...
