Researchers shed new light on how malaria parasites evade mosquitos' defences
Researchers shed new light on how malaria parasites evade mosquitos’ defences
The malaria parasite uses a specific molecule on its surface to get around a mosquito's immune system, allowing it to invade and infect humans. The molecule could be targeted by new transmission-blocking vaccines, or even thwarted by genetically modified mosquitos. The study, published today in Proceedings of the National Academy of Sciences , was led by scientists at Imperial College London.

Two brain systems for thinking about others’ thoughts
The brain seems to have two different systems enabling us to put ourselves in someone else's shoes, which develop at different ages, finds a new study involving UCL. The two systems mature at different times such that only four-year-olds can understand what another person is thinking, and not, as some have assumed, one-year-olds, according to the study published in Proceedings of the National Academy of Sciences (PNAS) .

Meteorite observation network sets out to catch a falling star
Imperial and Glasgow scientists are turning their eyes to the skies to track meteorites before they land on UK soil. The team are also looking for volunteers to help them recover the space rocks whenever and wherever they fall. We're looking for volunteers to help us catch these falling stars. These meteorites could help us understand our own planet and solar system - and maybe even the wider universe.
