An international consortium of researchers has used big data sets to predict the effects climate change on global wheat yields. Their multi-model predictions indicated global wheat production losses of 6% for each degree centigrade of global warming with increased variability of yield across regions and seasons.
In its first tests in humans, BBSRC-funded researchers at Imperial College London and the University of Glasgow found that the ingredient is effective at preventing weight gain in overweight volunteers. The ingredient contains propionate, which stimulates the gut to release hormones that act on the brain to reduce hunger.
New research by Dr Steve Penfield from the John Innes Centre has found that ‘mother’ plants remember the seasons and use this memory to teach their seeds the time of year and tell them when they should germinate. In his study of Arabidopsis thaliana, a common weed often used as a model for plant research, Dr Penfield found that the mother plant plays an important role in sensing temperature and forms a long term temperature memory which she uses to control the behaviour of her progeny seeds.
