MINI

Mini human brains, grown from stem cells and implanted into living mice, have for the first time been shown to respond to things the mice were seeing. Scientists were able to watch the responses in real time thanks to specialized graphene electrodes.

Scientists have grown mini eyes from human cells in the lab. These eye organoids provide good models of the real thing to help scientists study diseases that cause blindness and potentially find treatments.

Britain held its first free eco-car show in September demonstrating a variety of bicycles, cars and other environmental transport solutions.
