Peptides, which are short strings of amino acids, play a vital role in health and industry with a huge range of medical uses including in antibiotics, anti-inflammatory and anti-cancer drugs. They are also used in the cosmetics industry and for enhancing athletic performance. Altering the structure of natural peptides to produce improved compounds is therefore of great interest to scientists and industry. But how the machineries that produce these peptides work still isn't clearly understood.

Living in and on our bodies are trillions of microbial cells belonging to thousands of bacterial species, known as the microbiome. These microbes play key roles in human health, but little is known about their evolution. In a new study published in the Proceedings of the National Academy of Sciences, a multidisciplinary international research team led by scientists at the Max Planck Institute for the Science of Human History (MPI-SHH) investigated the evolutionary history of the hominid oral microbiome...

Southern California air quality officials have adopted first-of-their-kind rules on warehouse distribution centers in an effort to cut truck pollution, increase electrification and reduce health risks in communities hit hardest by lung-damaging diesel exhaust.

Scientists at UT Southwestern have discovered a key protein that helps the bacteria that causes Legionnaires' disease to set up house in the cells of humans and other hosts. The findings, published in Science, could offer insights into how other bacteria are able to survive inside cells, knowledge that could lead to new treatments for a wide variety of infections.

A team of researchers has discovered a fossil they are describing as a leftover fall event in which one creature was in the process of eating another creature that was not consumed. In their paper published in the Swiss Journal of Palaeontology, the group describes the fossilized find and what it taught them about behavior between ancient cephalopods and vertebrate predators.

Physical principles can be incorporated in a machine learning architecture as a fundamental setup to develop artificial intelligence for inorganic materials. In a new report now on Science Advances, Huta R. Banjade, and a research team in physics, computer and information science and nanoscience in the U.S. and Belgium proposed structure motifs in inorganic crystals to serve as a central input to a machine learning framework. The team demonstrated how the presence of structure motifs and their connections... Читать дальше...

A team of astronomers from the Grenoble Alpes University in France and elsewhere, reports the detection of a new sub-Neptune exoplanet orbiting an M dwarf star. The newly found alien world, designated TOI-269 b, is nearly three times larger than the Earth. The finding was detailed in a paper published April 30 on the arXiv pre-print repository.
