It has been a busy few weeks in the science arena. In the shadow of NASA’s announcement on the “Earth-like” planets around other stars, we heard that we no longer need to have our five portions of fruit and veg a day. We should now be aiming for 10 portions a day. The more, the merrier if you want to significantly reduce your chances of getting heart disease, stroke and cancer. In China significant inroads have been taken on the road to clean nuclear fusion, with a major breakthrough in burning hydrogen at a temperature hotter than our sun for well over a minute. This is one of the key requirements for a fusion reactor, which would offer unlimited clean energy and a move away from fossil fuels.
