  • Researchers generate plants with enhanced drought resistance without penalizing growth
    on November 8, 2018 at 2:13 pm

    Extreme drought is one of the effects of climate change that is already being perceived. A team has obtained plants with increased drought resistance by modifying the signaling of the plant steroid hormones, known as brassinosteroids. The study is among the first to find a strategy to increase plant hydric stress resistance without affecting overall plant growth. […]

  • One million years of precipitation history of the monsoon reconstructed
    on November 8, 2018 at 2:13 pm

    With its wind and precipitation patterns, the South Asian Monsoon influences the lives of several billion people. Recent studies indicate that its drivers are more complex than previously assumed. Scientists have now published a reconstruction of precipitation over the eastern Indian Ocean over the past one million years. It points to connections with controlling processes in the southern hemisphere that have received little attention so far. […]

  • Controlling future summer weather extremes still within our grasp
    on October 31, 2018 at 6:16 pm

    Continued burning of fossil fuels is likely to fuel even more extreme summers than that of 2018 because of its impact on the jet stream. The rapid disappearance of aerosols produced by pollution may, however, mitigate the impact until mid-century if countries like China phase out these fuels, according to scientists using climate models to predict changes in the occurrence of so-called Quasi-Resonant Amplification (QRA) events associated with persistent weather extremes. […]

  • How plants cope with stress
    on October 30, 2018 at 7:06 pm

    With climate change comes drought, and with drought comes higher salt concentrations in the soil. Scientists have identified a mechanism by which plants respond to salt stress, a pathway that could be targeted to engineer more adaptable crops. […]

  • how climate change could cause global beer shortages
    on October 15, 2018 at 3:35 pm

    Severe climate events could cause shortages in the global beer supply, according to new research. The study warns that increasingly widespread and severe drought and heat may cause substantial decreases in barley yields worldwide, affecting the supply used to make beer, and ultimately resulting in 'dramatic' falls in beer consumption and rises in beer prices. […]

  • Tomatoes 'mixing chemical cocktails': Early detection of disease resistance in food crops
    on September 27, 2018 at 12:33 pm

    Bacterial wilt devastates food crops world-wide. It destroys major crop plants such as tomatoes, potatoes, bananas and ginger. So far farmers have had to plant and wait for mature plants to observe resistance. Now research shows a possible way of saving time and reducing risk significantly for farmers and plant breeders. A new approach promises to forecast cultivar resistance at seedling stage. Scientists use plant metabolomics and statistics to decode the plants' chemical defenses. […]
