A brain-computer interface allows a severely paralysed patient not only to move and use a robotic arm, but also to feel the sensations as the mechanical hand clasps objects . We hear from Jennifer Collinger at Pittsburgh University’s Rehab Neural Engineering Labs. And Nathan Copeland, who has been controlling the robotic arm with his thoughts via a series of brain implants.Ralph Baric of the University of North Carolina tells us about the development of a multi-component vaccine that would be effective not just against the current coronavirus outbreak and its variants, but also future outbreaks from SARS-like coronaviruses that we don’t even know about yet.Blood clots, thromboses, have been a problem for a small number of people following Covid vaccination Paul Knöbl, and a team of medics in Vienna have worked out the link between vaccination and clot development.
