  • How wheat can root out the take-all fungus
    on May 22, 2018 at 12:21 pm

    In the soils of the world's cereal fields, a family tussle between related species of fungi is underway for control of the crops' roots, with food security on the line. Beneficial fungi can help plants to protect themselves from cousins eager to overwhelm the roots, but it's a closely fought battle. Working out the right conditions to support those beneficial fungi and identifying the cereal varieties that are best suited to make the most of that help is no mean task. […]

  • The chestnut gall wasp -- The threat of an invasive species with clonal reproduction
    on May 21, 2018 at 6:38 pm

    A molecular study carried out on the chestnut gall wasp, Dryocosmus kuriphilus, has revealed the absence of genetic variability in this invasive species, a chestnut-tree parasite, in Europe. This is due to the fact that the wasp's reproduction is strictly parthenogenetic, the females produce more females without having to be fertilized by a male. The high capacity of reproduction of the females, producing genetically identical daughters, give this insect a high invasive potential. […]

  • Deadly malaria's evolution revealed
    on May 21, 2018 at 5:18 pm

    The evolutionary path of the deadliest human malaria parasite, Plasmodium falciparum, has been revealed for the first time. This parasite is a member of the Laverania parasite family that only infect the great apes including humans, chimpanzees and gorillas. Scientists estimate that Plasmodium falciparum emerged as a human-specific parasite species earlier than previously thought. […]

  • Quantum effects observed in photosynthesis
    on May 21, 2018 at 5:17 pm

    Molecules that are involved in photosynthesis exhibit the same quantum effects as non-living matter, concludes an international team of scientists.

  • Scientists find link between increases in local temperature and antibiotic resistance
    on May 21, 2018 at 5:17 pm

    Bacteria have long been thought to develop antibiotic resistance largely due to repeated exposure through over-prescribing. But could much bigger environmental pressures be at play? […]

  • Profiling the genome hundreds of variations at a time
    on May 21, 2018 at 5:17 pm

    Using baker's yeast, a team at Harvard's Wyss Institute developed a CRISPR-Cas9-based high-throughput approach that allows researchers to precisely alter hundreds of different genes or features of a single gene at once in individual yeast cells with 80 to 100% efficiency, select cells from the population that show specific behaviors, and identify the gene alterations that either trigger or prevent them. […]

  • Autism is not linked to eating fish in pregnacy
    on May 21, 2018 at 5:17 pm

    A major study examining the fish-eating habits of pregnant women has found that they are not linked to autism or autistic traits in their children. Scientists looked at the assumption that mercury exposure during pregnancy is a major cause of autism using evidence from nearly 4,500 women who took part in the Children of the '90s study. […]

  • Researchers discover how body temperature wrecks potential dengue, Zika vaccine
    on May 18, 2018 at 6:10 pm

    A major route toward creating effective vaccines against dengue virus and Zika involves the E protein that covers the surface of each viral particle. But creating such a vaccine has proven difficult for a number of reasons. Now researchers have delineated the details of one major barrier to a promising vaccine. It's something we all have -- a natural body temperature of about 98.6 degrees. […]
