Scientists create a super antioxidant: Common catalyst cerium oxide opens door to nanochemistry for medicine
Scientists at Rice University are enhancing the natural antioxidant properties of an element found in a car's catalytic converter to make it useful for medical applications.
(PhysOrg.com) -- After the biggest mass extinction in Earth's history -- 250 million years ago -- ocean algae and bacteria rebounded so fast that they consumed virtually all the oxygen in the sea, slowing the recovery of ...
By swapping out one specific hydrogen atom for an isotope twice as heavy, researchers have increased the shelf life and detection ability of fluorescent probes that are essential to studying a variety of inflammatory diseases, ...
For decades, microbiologists assumed that macrophages, immune cells that can engulf and poison bacteria and other pathogens, killed microbes by damaging their DNA. A new study from the University of Illinois disproves that.
A gene that helps plants to remain healthy during times of stress has been identified by researchers at Oxford University. Its presence helps plants to tolerate environmental pressures like drought—and it could help create ...
Research on a helpful part of the microbiome—beneficial intestinal bacteria—is moving from "what is there" to "how they help."
Modern mountain climbers typically carry tanks of oxygen to help them reach the summit. It's the combination of physical exertion and lack of oxygen at high altitudes that creates one of the biggest challenges for mountaineers.
