    on March 23, 2018 at 2:48 pm

    Cell division is the basis of all life. Even the smallest errors in this complex process can lead to grave diseases like cancer. Certain proteins have to be switched on or off at certain times for everything to go according to plan. Biophysicists and medical biochemists have managed to describe the underlying mechanism of this process. […]

  • Bacteria eat greenhouse gas with a side of protein
    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. The efficiency of malaria treatment with mostly used drugs is undermined by resistant lineages and by the fact that patients present severe side effects in 10 percent of the cases. […]

  • The mouse brain can prioritize hunger by suppressing pain when survival is at stake
    on March 22, 2018 at 6:10 pm

    Different behaviors are often studied in isolation, leaving unanswered questions about how the brain processes needs and prioritizes behaviors to ensure survival. Now, researchers have shown that pain and hunger interact in complex ways in mice: extreme hunger suppresses less-urgent inflammatory pain, but leaves them able to feel and react to more life-and-death kinds of pain. The study pinpoints a highly specific neural circuit that creates this analgesic effect. […]

  • Blackbirds in the city: Bad health, longer life
    on March 22, 2018 at 2:33 pm

    on March 22, 2018 at 2:32 pm

    The population of bacteria in the pancreas increases more than a thousand fold in patients with pancreatic cancer, and becomes dominated by species that prevent the immune system from attacking tumor cells. […]

  • Plants really do feed their friends
    on March 22, 2018 at 2:32 pm

    Researchers have discovered that as plants develop they craft their root microbiome, favoring microbes that consume very specific metabolites. Their study could help scientists identify ways to enhance the soil microbiome for improved carbon storage and plant productivity. […]

  • 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. […]

    on March 21, 2018 at 8:22 pm

    Diets rich in mono-unsaturated fats from plants may lower the risk of death from heart disease and other causes. The largest reductions in the risk of death were found when healthy fats from plant sources replaced saturated fats, trans fats and refined carbohydrates. […]

  • Grilling and other high-temperature cooking may raise risk of high blood pressure
    on March 21, 2018 at 8:22 pm

  • 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. […]

  • Elephant and cow manure for making paper sustainably
    on March 21, 2018 at 1:09 pm

    It's likely not the first thing you think of when you see elephant or cow dung, but this material turns out to be an excellent source of cellulose for paper manufacturing. Upcycling manure into paper products could be a cheap and environmentally sound method to get rid of this pervasive agricultural waste. […]

  • 'Wiggling and jiggling': Study explains how organisms evolve to live at different temperatures
    on March 21, 2018 at 1:08 pm

    New research explains how the 'wiggling and jiggling' of the atoms in enzymes -- the proteins that make biological reactions happen -- is 'choreographed' to make them work at a particular temperature. Enzyme catalysis is essential to life, and this research sheds light on how enzymes have evolved and adapted, enabling organisms to evolve to live at different temperatures. […]

  • Fixing soybean's need for nitrogen
    on March 21, 2018 at 1:08 pm

    To make protein, soybean plants need a lot of nitrogen. Beneficial bacteria in root nodules typically assist. A new study shows it's possible to increase the number of soybean root nodules--and the bacteria that live there--to further increase crop yields. This could remove the need to apply additional nitrogen fertilizers. […]
