July 13, 2021 Antimicrobials are used to kill or slow the growth of bacteria, viruses and other microorganisms. They are essential to preventing and treating infections, but they also pose a global threat to public health when microorganisms develop antimicrobial resistance. A lab studied the mechanisms behind bacterial resistance to silver nanoparticles to determine if their ubiquitous use is a solution to ...

July 13, 2021 Scientists have developed a computational method based on large-scale molecular dynamics simulations to predict the cell-membrane permeability of cyclic peptides using a supercomputer. Their protocol has exhibited promising accuracy and may become a useful tool for the design and discovery of cyclic peptide drugs, which could help us reach new therapeutic targets inside cells beyond the ...

July 13, 2021 Crenarchaeol is a large, closed-loop lipid that is present in the membranes of ammonium-oxidizing archaea. In comparison to other archaeal membrane lipids, crenarchaeol is very complex and, so far, attempts to confirm its structure by synthesizing the entire molecule have been unsuccessful. Organic chemists have now taken up this challenge and ...

July 13, 2021 Astronomers see many periodic emissions from space, typically caused by rotation of stars and often very regular. Astrophysicists noticed a unique periodicity in the soft gamma ray emissions from a magnetar located in our galaxy. The soft gamma repeater SGR1935+2154 appears to emit bursts only within regularly spaced windows, and is inactive in between. Based on their analysis, they predicted a ...

July 12, 2021 In the vicinity of black holes, space is so warped that even light rays may curve around them several times. This phenomenon may enable us to see multiple versions of the same thing. While this has been known for decades, only now do we have an exact, mathematical ...

July 13, 2021 Researchers have developed a new device that harvests energy from the sweat on -- of all places -- your fingertips. To date, the device is believed to be the most efficient on-body energy harvester ever invented, producing 300 millijoules (mJ) of energy per square centimeter without any mechanical energy input during a 10-hour sleep and an additional 30 mJ of energy with a single press of a ...
