Where the microbe Prochlorococcus lives is not determined primarily by temperature, as previously thought. A study finds a relationship with a shared predator actually sets the microbe's range. The findings could help scientists predict how Prochlorococcus populations will shift with climate change.
Membrane-associated proteins play a vital role in a variety of cellular processes, yet little is known about the membrane-association mechanism. Lipoprotein-associated phospholipase A2 (Lp-PLA2) is one such protein with an important role in cardiovascular health, but its mechanism of action on the phospholipid membrane was unknown. To address this, researchers at University of California San Diego...
Natural camouflage is one of nature's most interesting traits. Materials scientists have now developed a material that can mimic the camouflage capabilities of marine mollusks. They created a starfish-shaped soft robot that responds to heat and pressure with deformation, movement, and color changes. Cut-off tentacles can be welded together, and the material can be fully recycled, they write in the...
Mutations in genes encoding mitochondrial aminoacyl-tRNA synthetases are linked to diverse diseases. However, the precise mechanisms by which these mutations affect mitochondrial function and disease development are not fully understood.
The Transiting Exoplanet Survey Satellite, TESS, was launched in 2018 with the goal of discovering small planets around the sun's nearest neighbor stars. TESS has so far discovered 172 confirmed exoplanets and compiled a list of 4703 candidate exoplanets. Its sensitive camera takes images that span a huge field of view, more than twice the area of the constellation of Orion, and TESS has also...
Carbon dioxide can be harvested from smokestacks and used to create commercially valuable chemicals thanks to a novel compound developed by a scientific collaboration led by an Oregon State University researcher.
Prochlorococcus are the smallest and most abundant photosynthesizing organisms on the planet. A single Prochlorococcus cell is dwarfed by a human red blood cell, yet globally the microbes number in the octillions and are responsible for a large fraction of the world's oxygen production as they turn sunlight into energy.
The microbes that live inside our mouths, collectively known as the oral microbiome, impact our overall health in many ways that are not yet fully understood. Some bacteria cause inflammation, leading to periodontitis and other systemic diseases, such as cardiovascular disease and diabetes. Other oral organisms have been associated with certain types of cancer. Scientists are working to understand...
