Santoriello Researchers at The City College of New York have uncovered a novel way in which Vibrio cholerae, the aquatic microbe that causes cholera, may increase its competitive fitness, and […]

Our galaxy’s supermassive black hole is closer to Earth than we thought

The supermassive black hole hiding in the center of our galaxy is much closer to Earth, about 2,000 light-years closer, than scientists thought, according to new research out of Japan.  Not only that but our solar system is moving faster than thought as it orbits this galactic center.  All this doesn’t mean you need to […]

New class of cobalt-free cathodes could enhance energy density of next-gen lithium-ion batteries — ScienceDaily

Oak Ridge National Laboratory researchers have developed a new family of cathodes with the potential to replace the costly cobalt-based cathodes typically found in today’s lithium-ion batteries that power electric vehicles and consumer electronics. The new class called NFA, which stands for nickel-, iron- and aluminum-based cathode, is a derivative of lithium nickelate and can […]

Topological phases in biological systems

Interaction chain. Credit: C. Hohmann LMU physicists have shown that topological phases could exist in biology, and in so doing they have identified a link between solid-state physics and biophysics. The concept of topological phase transitions has become an important topic in theoretical physics, and was first applied to the characterization of unusual states of […]
