This question is fundamental for infectious disease experts and people who study bacteria. Harmful pathogens, like Salmonella, find their way through a complex gut system where they are vastly outnumbered by good microbes and immune cells. Still, the pathogens navigate to find vulnerable entry points in the gut that would allow them to invade and infect the body. /news/2024-08-electric-current-gut-pathogens-salmonella.html Cell & Microbiology Molecular & Computational biology Wed, 21 Aug 2024 10:45:04 EDT news643455902 Just a single, unguarded glance at a solar eclipse can result in a lifetime of vision loss, eye health experts warn. /news/2024-04-unprotected-eclipse-stars.html Space Exploration Sun, 07 Apr 2024 13:50:01 EDT news631715739 "Oh, hello.
