Revolutionary batteries which could cut the cobalt pattern of an electric car were designed by chemists at MIT. More specifically, they found a better alternative to the material of cathode (positively charged electrode) in lithium-ion batteries. Cobalt, the metal used up until now, has other than the capacity to store loads of energy many more drawbacks, concerning unstable price, unjust mining background or toxicity towards the environment. Because of that, many scientists set their goal to find less problematic material, favorably organic one. In the MIT lab, researchers created a material with a structure similar to graphite, which seems to even outstand cobalt in some ways, for example, more rapid charging. Contented with these results, they now plan to find a replacement for lithium and with the newly proven history, they might as well succeed.
If you are ambitious, do not hesitate to consider MIT as one of your choices…
On the grounds of University College London, special research is being done to diagnose the early stage of Alzheimer's disease. There are two major parts in which the patients are tested - firstly via blood tests and secondly through various paper tests of their cognitive skills. None of these can identify dementia one hundred percent correctly so a team from the university tries to find a way how to unite the process internationally - using modern virtual reality technologies. The patient has to put on a VR headset and follow instructions which are displayed around him, resulting in a challenge for their navigation and memory skills. Potentially this could detect many early signs of the disease with a brighter prospect of future life.
