In eukaryotic cells, molecules can only move into or out of the nucleus through specialized channels called nuclear pore complexes (NPCs). Each NPC has a ring of nucleoporin proteins flanking either end of the central channel, which usually share an identical structure. But in fission yeast Schizosaccharomyces pombe, researchers led by Osaka University have found that the NPC outer ring structures are completely asymmetrical, shedding new light on the structure and function of the nucleus.
Scientists from the Universities of Regensburg and Mainz and the Max Planck Institute for Chemical Ecology discovered that the eggs of the European beewolf produce nitric oxide. The gas prevents the larvae's food from getting moldy in the warm and humid brood cells. The results were published in the Journal eLife.
New Guinea is one of the only places in the world where frogs are safe from the chytrid fungus that has made more than 90 species extinct. An international team of scientists has published a new paper that shows how to keep it that way, but they need help to carry out their plan.
Illinois wheat growers, take heart. A new University of Illinois study shows no evidence of a highly toxic Fusarium head blight (FHB) variant, known as NA2, in the wheat-growing region of the state. The study also reinforces the effectiveness of wheat resistance to the fungal disease.
A team of researchers from Tokyo University of Science, Meiji University, and Tokyo University of Agriculture and Technology, led by Professor Takayuki Arazoe, has recently established a series of novel strategies to increase the efficiency of targeted gene disruption and new gene 'introduction' using the CRISPR/Cas9 system in the rice blast fungus Pyricularia (Magnaporthe) oryzae.
Cryptococcal meningitis causes about one in ten HIV-related deaths, according to a study of autopsies performed in Mozambique and Brazil and coordinated by the Barcelona Institute for Global Health (ISGlobal), an institution supported by 'la Caixa'.
Most living things have a suite of genes dedicated to repairing their DNA, limiting the rate at which their genomes change through time. But scientists at Vanderbilt and University of Wisconsin-Madison have discovered an ancient lineage of budding yeasts that appears to have accumulated a remarkably high load of mutations due to the unprecedented loss of dozens of genes involved in repairing errors in DNA and cell division, previously thought to be essential.
In 2020, NASA and European-Russian missions will look for evidence of past life on Mars. But while volcanic, igneous rock predominates on the Red Planet, virtually the entire Earth fossil record comes from sedimentary rocks. Addressing the problem in Frontiers in Earth Science, Swedish scientists have begun compiling evidence of fossilized microbes in underexplored igneous rock environments on Earth, to help guide where to search for a Martian fossil record - and what to look for.
Insights into the genes and proteins involved in the predatory behavior of a parasitic yeast species could lead to new strategies for controlling yeast pathogens, according to a study published May 9 in the open-access journal PLOS Pathogens by Jürgen Wendland of the Carlsberg Research Laboratory in Denmark and Vrije Universiteit Brussel in Belgium, and colleagues.
A species of globally recognised medicinal mushroom was recorded for the first time in Thailand. Commonly referred to as lingzhi, the fungus (Ganoderma tropicum) was collected from the base of a living tree in Chiang Rai Province, Northern Thailand. In their study, published in the open-access journal MycoKeys, the scientists also report the first assessment of the optimum conditions needed for the species to grow its mycelia and spread its colony.
