  • Knowing. Bacteria’s memory (x 100). Humans…

    Researchers have identified a mutation that prompts bacterial cells to acquire genetic memories 100 times more frequently than they do naturally. This discovery provides a powerful research tool and could bring scientists one step closer to developing DNA-based data storage devices. (1) We insist on making the cosmos a big computer. We want to make […]

  • Bacteria mind games…

    By tinkering with the gut’s bacterial residents, scientists have changed the behavior of lab animals and small numbers of people. Microbial meddling has turned anxious mice bold and shy mice social. Rats inoculated with bacteria from depressed people develop signs of depression themselves. And small studies of people suggest that eating specific kinds of bacteria […]

  • Bacteria. Viruses. Good. Bad…

    Normally, you wouldn’t want to have anything to do with Clostridium novyi. The rod-shaped bacterium is commonly found in soil, manure or under rotting leaves. When it invades a human body, it releases flesh-eating toxins. The last place you would hope to find it is in a hospital. But researchers used a modified version of […]

  • Gut, viruses, life itself…

    Odds are, there’s a virus living inside your gut that has gone undetected by scientists for decades. A new study has found that more than half the world’s population is host to a newly described virus, named crAssphage, which infects one of the most common gut bacterial species, Bacteroides. This bacterium thought to be connected […]

  • Curiosity, microbes, observing.

    A recent study of swabs taken from the rover before it launched found its surfaces contained 65 bacteria species. Engineers are supposed to put spacecraft like Curiosity through a stringent cleaning regimen before launch. Yet certain species of bacteria are known to survive even NASA’s cleanrooms. Wondering about what remained on Curiosity even after cleaning, […]
