Tech Xplore / Improved method for producing sustainable hydrogen offers a surprising side benefit
Producing hydrogen is essential for some of the world's biggest industrial and agricultural needs, but it also comes with a steep environmental cost: Most hydrogen made today is generated through processes that release large ...
Phys.org / Pigment found in beets linked to plants' adaptation to harsh environments
The pigments that give beets their red color may have helped a major group of flowering plants repeatedly adapt to dry environments, setting the stage for the evolution of traits that allowed plants to adapt to some of the ...
Phys.org / Rising species numbers on Europe's mountaintops may mask increasing losses of high-elevation plant specialists
Decades of warming have relaxed cold-temperature constraints on mountain plant distribution and increased species numbers on mountaintops. An international research team led by scientists from the University of Vienna, together ...
Medical Xpress / Three psychedelic drugs affect the brain differently, brain scans in rats suggest
In recent years, psychedelic drugs have attracted growing interest as potential treatments for conditions including depression, anxiety and addiction. Although these drugs are often considered one group, researchers from ...
Medical Xpress / C. difficile colonization in infants reshapes gut development, challenging a long-held assumption
Since its discovery, the highly contagious bacterium Clostridioides difficile (C. difficile or C. diff) has been reported not to cause symptoms in infants, leading to the assumption that colonization was not a serious health ...
Tech Xplore / Study shows plug-in hybrids polluting far more than expected
Plug-in hybrids have enjoyed a surge in popularity, but a study published Thursday showed they are polluting far more than most buyers think because they rely on batteries less often than regulators expected.
Phys.org / Metabolic networks provide clues about the earliest stages of enzyme evolution
The enzymes found in modern organisms are complex proteins, often with multiple folded substructures and specialized catalytic sites. Proteins are encoded by genes. Tracing the history of enzymes across all living organisms ...
Phys.org / How stressed cells put the brakes on protein 'shipping'
Cells synthesize proteins in the endoplasmic reticulum (ER), and these proteins are transported to the Golgi apparatus for distribution to their ultimate destinations inside and outside the cell. The structures that transport ...
Phys.org / Heat has a memory—and a new theoretical framework can track it
Heat, it turns out, has a memory. A cooling cup of coffee may not seem particularly thoughtful. At the scale of a kitchen, heat appears to follow a straightforward rule: it moves from warmer places to cooler ones. Leave the ...
Phys.org / Surf's up: How the seafloor shapes breaking waves
A new study led by surfing scientists at the Scripps Institution of Oceanography at UC San Diego revealed the physical relationships underlying a pattern familiar to generations of surfers.
Phys.org / Light-triggered interface lets adhesive peel cleanly and rebond through 15 cycles
Adhesives are essential in electronics, vehicles and other products, but they can hinder repair and recycling when bonded parts are difficult to separate cleanly. A research team led by The University of Osaka has developed ...
Phys.org / First switchable graphene nanoribbon that twists on demand
Researchers at Nagoya University have built a graphene nanoribbon that can switch the direction of its twist using a natural solvent. Graphene nanoribbons are thin, ribbon-shaped structures made of fused carbon rings. Twisted ...
