Scientists have identified the genetic mutations that cause sickle cells in deer, according to new research in the journal Nature Ecology & Evolution. The team of researchers led by Dr Tobias Warnecke from Imperial’s Institute of Clinical Sciences, which included Professor Vincent Savolainen, analysed the genetic make-up of sickled and non-sickled red blood cells (RBCs) in 15 species of deer, and compared them to our current knowledge of how the trait came about in humans. They found that the sickle trait in deer took a different evolutionary path to the trait in humans. Click here to find out more.
The world's rainforests take up extra carbon dioxide in the atmosphere, but their ability to do so is threatened by drought and fragmentation. A team of researchers monitored tens of thousands of trees in over a dozen locations across Borneo, for up to half a century, showing that these forests increased the amount of carbon they stored (their ‘carbon stock’) by 430 kg per hectare per year. Lead author Dr Lan Qie, who conducted the research at the University of Leeds and is now based in the Department of Life Sciences at Silwood Park, said: “Borneo’s remaining rainforests are increasing in size, adding to their already high carbon stocks.'

Researchers get their first look at how the toxic protein clusters associated with Parkinson's disease disrupt the membranes of healthy brain cells. The research findings, published in Science and led by researchers from Imperial College London and the University of Cambridge, will help researchers hoping to find a way to stop these agents from entering and damaging cells, leading to new and more effective treatments for the illness. Dr Alfonso De Simone, one of the study’s lead authors, explained: “It is a bit like if you put a piece of extremely hot metal on to a plastic surface. In a fairly short space of time it will burn a hole through the plastic. Click here to find out more.
Scientists have identified a protein involved in the life cycle of the malarial parasite, paving the way for a new vaccine to reduce disease spread. Following a two-year study, researchers at Imperial have unlocked an innovative way to break this vicious circle by inhibiting the parasites’ life cycle at the point of fertilisation. Dr Fiona Angrisano, lead author of the study said: “We’re really encouraged by the initial findings of this study. The fact that we were able to reduce the number of fertilisation events by blocking just a small part of HAP2 is promising, as this could be a cheap and easy target in the search for vaccines that will lower the transmission rates of malaria.” Click here to find out more.
In a surprise ecological finding, researchers discover medium-sized carnivores spend the most time looking for food, making them vulnerable to change. It had been thought that foraging time decreases as animal size increases, but new research by Imperial College London and the ZSL (Zoological Society of London) shows this is not the case. Study co-author Dr Samraat Pawar said: “We propose a simple mathematical model that predicts how foraging time depends on body size. This can help predict potential risks to predators facing environmental change. Click here to find out more.
