Robot revolution

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. They now have a method to treat such clots – so they should not be fatal.

And how did fungi and plants come to live together? Symbiotic relationships between the two are a key component of the evolution of life. Melanie Rich of the University of Toulouse has been looking at the present day genetic markers which allowed plants and fungi to help each other as they first colonised land millions of years ago.
