One of the great frustrations of modern medicine is the creeping ability of pathogenic microbes to develop resistance to the antibiotics we throw at them.
More and more, microbes are able to eliminate, modify and sequester the toxic molecules that make up the arsenal of antibiotics that humans use to treat infection, making once-miraculous drugs increasingly impotent. Now, adding to the mix of devices dangerous microbes deploy to evade destruction by antibiotics, scientists have discovered another way pathogens escape from the most potent drugs: self-sacrifice.
It is the equivalent of the courageous soldier throwing himself on a grenade, says Jon S. Thorson, a University of Wisconsin-Madison professor of pharmacy and the senior author of a paper describing the newfound method of antibiotic resistance published in this weeks (Sept. 12) edition of the journal Science.

New research group at the University of Jena combines theory and experiment to demonstrate for the first time certain physical processes in a quantum vacuum
For most people, a vacuum is an empty space. Quantum physics, on the other hand, assumes that even in this lowest-energy state, particles and antiparticles...

Combining an atomically thin graphene and a boron nitride layer at a slightly rotated angle changes their electrical properties. Physicists at the University of Basel have now shown for the first time the combination with a third layer can result in new material properties also in a three-layer sandwich of carbon and boron nitride. This significantly increases the number of potential synthetic materials, report the researchers in the scientific journal Nano Letters.
Last year, researchers in the US caused a big stir when they showed that rotating two stacked graphene layers by a “magical” angle of 1.1 degrees turns...
