Lactobacillus parafarraginis metabolites hindered the growth of multiple, distantly related bacterial pathogens.

Bacteria riding on an incoming meteorite may be able to survive the violent shockwave created when it crash-lands on a planet. Their cell walls have been seen to rapidly harden and relax after a sudden shock compression, enabling them to bounce back even after an extreme collision.

Researchers have found a way to penetrate the cell wall of gram-negative bacteria, overcoming a major barrier to the development of new broad-spectrum antibiotics.

Another connection between the gut and the brain.

You may have already heard about the growing problem caused by antibiotic resistance - the spread of superbugs that have evolved to become resistant to the antibiotics we usually attack them with. It's an issue that could have very serious implications for global health and disease if it isn't tackled urgently, and now researchers have made an important step in finding a solution.
