Neutrons help measure cell membrane viscosity—and reveal its basis
We now have a clearer picture of the lightning-fast molecular dance occurring within the membrane that encloses each cell in our body, revealed in part by neutron beams at the National Institute of Standards and Technology (NIST). The findings may ha.....»»
How a protein keeps gene clusters quiet in the cell nucleolus
In a discovery that sheds light on the complex mechanisms of gene regulation, scientists at EPFL have uncovered a critical role for the protein ZNF274 in keeping certain gene clusters turned off by anchoring them to the cell nucleolus. The study is p.....»»
How iron and metabolic constraints can aid gene discovery for photosynthesis and biofuel production
The single-cell green alga Chromochloris zofingiensis is an emerging model organism for photosynthesis and metabolism research. Previous research has shown that with the addition of glucose, Chromochloris zofingiensis shuts off photosynthesis, rerout.....»»
Elucidating the mechanism of cell division during plant self-healing
When the stem of a plant is injured, the surrounding cells proliferate to repair and fuse the damaged tissue, eventually restoring function. This self-healing property is utilized in grafting techniques to propagate fruit and vegetable plants......»»
Enhancing hurricane forecasts: Simulations reveal reducing estimates of atmospheric friction improves storm predictions
Hurricanes and other extreme weather events are expensive in lives and money. From 1980 to 2023, weather and climate disasters caused about $2.6 trillion in damages in the U.S., according to NOAA estimates. In 2022 alone, the U.S. experienced 18 disa.....»»

Cretaceous fireflies reveal early evolution of insect bioluminescence
Bioluminescence, the ability of living organisms to emit light, is a fascinating phenomenon observed in various life forms, including deep-sea fish, glowing mushrooms, and fireflies. Fireflies have long captivated people with their enchanting light d.....»»
Biologists sequence proteins by pulling them through nanopores
A team of chemical biologists at the University of Washington, working with colleagues at Oxford Nanopore Technologies, has developed a protein sequencing process that involves pulling proteins through nanopores in a lipid membrane. Their paper is pu.....»»
Who lives in the rainforest treetops? DNA-collecting drone provides insights
Squinting into the treetops won't reveal the tiny organisms up there. But these creatures leave clues, in the form of DNA, on the leaves and branches. Now, researchers report in Environmental Science & Technology that they have developed a way to col.....»»
Semimetal-induced covalency achieves high-efficiency electrocatalysis for platinum intermetallic compounds
Compared with other types of batteries, proton exchange membrane fuel cells have the advantages of high discharge power and no pollution, which is also an important carrier for hydrogen energy conversion and utilization. Platinum intermetallic compou.....»»
