This video shows dendritic cells moving through a chemical gradient in a microfluidic device. This component will be used to connect skin cells to an artificial lymph node, and mimic an allergic response. Once complete, the whole test might allow for the elimination of skin allergy testing on animals.
Two antenna feeds move freely around the outside of this compact lens, which is intended to provide broadband Internet access to trains that have to go through narrow tunnels. Each feed is capable of sending and receiving a different satellite signal.
