  • New antifungal provides hope in fight against superbugs
    on January 12, 2018 at 6:29 pm

    Microscopic yeast have been wreaking havoc in hospitals around the world -- creeping into catheters, ventilator tubes, and IV lines -- and causing deadly invasive infection. One culprit species, Candida auris, is resistant to many antifungals, meaning once a person is infected, there are limited treatment options. But researchers have now confirmed a new drug compound kills drug-resistant C. auris, both in the laboratory and in a mouse model that mimics human infection. […]

  • Northern corn leaf blight genes identified in new study
    on January 12, 2018 at 3:40 am

    Midwestern corn growers know the symptoms of northern corn leaf blight all too well: greenish-gray lesions on the leaves that can add up to major yield losses if not detected and treated early. Corn resistance genes have been identified, but the fungal disease has found ways to sneak around corn's defenses. Now, researchers have discovered how the fungus is outsmarting corn, and they may be able to use this information to help corn fight back. […]

  • Dead trees are alive with fungi
    on January 9, 2018 at 4:24 pm

    So far, little research has been conducted on fungi that live on dead trees, although they are vital to the forest ecology by breaking down dead wood and completing the element cycle between plants and soil. Soil biologists have now discovered that the number of fungus species inhabiting dead trees is 12 times higher than previously thought. Once trees die they are also colonized by different fungal communities depending on their species. […]

  • Agricultural fungicide attracts honey bees
    on January 8, 2018 at 5:10 pm

  • Wheat disease breakthrough to help feed the world
    on December 21, 2017 at 7:30 pm

    Famine may be largely a thing of the past but in recent years the re-emergence of a disease that can kill wheat -- which provides a fifth of humanity's food -- has threatened food security; now a wheat stem rust breakthrough is being announced. […]

  • Climate change: Soil animals cannot explain self-reinforcing effect
    on December 21, 2017 at 3:13 pm

    When the soil warms up, it releases more carbon dioxide (CO2) -- an effect that further fuels climate change. Until now, it had been assumed that the reason for this was mainly due to the presence of small soil animals and microorganisms that would eat and breathe more in warmer temperatures. However, a new study has shown that this is not the case. Quite the contrary: If warmth is accompanied by drought, the soil animals eat even less. […]

  • How fungi helped create life as we know it
    on December 18, 2017 at 2:06 pm

  • Lichen that changes its reproductive strategy according to the climate
    on November 29, 2017 at 4:00 pm

    Symbiosis between fungi and microalgae gives rise to lichen. Some lichen, however, such as Lobaria scrobiculata, have a unique feature: the fungus establishes a symbiosis with a cyanobacteria, thus requiring water in liquid form to activate photosynthesis. According to a new study, this forces the lichen to concentrate its resources on reproduction in places where water is scarce. For the first time, this study demonstrates the theory of life strategies in fungi. […]

  • Cell cycle proteins help immune cells trap microbes with nets made of DNA
    on November 20, 2017 at 5:45 pm

    In your bloodstream, there are immune cells called neutrophils that, when faced with a pathogenic threat, will expel their DNA like a net to contain it. These DNA snares are called neutrophil extracellular traps or NETs. Researchers describe an important step in how these NETs are released and how they stop a fungus from establishing an infection in mice and human cells. […]

  • Raindrops splash pathogens onto crops
    on November 20, 2017 at 2:00 pm
