    on March 22, 2018 at 7:03 pm

    With the ability to leech heavy metals from the environment and digest a potent greenhouse gas, methanotrophic bacteria pull double duty when it comes to cleaning up the environment. But before researchers can explore potential conservation applications, they first must better understand the bacteria's basic physiological processes. New research has identified two never-before-studied proteins, called MbnB and MbnC, as partially responsible for the bacteria's inner workings. […]

  • Antimicrobial used in toiletries could become option against malaria
    on March 22, 2018 at 7:03 pm

    Not only it inhibits enzymes essential to Plasmodium's survival in two key stages of its lifecycle in humans, but triclosan also performed well in tests against resistant parasites, an international study reveals.

  • Brewing hoppy beer without the hops
    on March 21, 2018 at 8:22 pm

    Synthetic biology has created microbes that produce drugs, flavors, aromas and fuels. Now scientists have used the same tricks, with the help of CRISPR-Cas9, to get yeast to produce the flavor of hops. They added genes from mint and basil and used the yeast to brew a beer that tasters said had notes of 'fruit-loops' and 'orange blossom,' with no off flavors. The yeast helps brewers avoid expensive, highly variable and water-guzzling hops. […]

  • Despite high blood sugar, cavefish live long, healthy lives
    on March 21, 2018 at 6:14 pm

    Mexican cavefish have insulin resistance, a hallmark of many human metabolic disorders and a precursor to type 2 diabetes that can lead to an overworked pancreas, excess fat storage and chronically elevated blood sugar. Despite dysregulated blood sugar, the fish don't suffer the same health consequences people do. Study offers a fresh opportunity to understand how animals thrive with traits that sicken humans and could point the way to new interventions for disease. […]

    on March 20, 2018 at 12:43 pm

    Bacterial infections that target the intestine can cause conditions that range from uncomfortable to deadly. While it's easy to blame the bacteria, it's actually the toxins the bacteria produce that trigger inflammation, diarrhea, fever and cramps. Researchers now report the development of a microgel scavenger that targets toxins instead of bacteria. […]
