A novel encryption method devised by MIT researchers secures data used in online neural networks and blends two conventional techniques — homomorphic encryption and garbled circuits — in a way that helps the networks run orders of magnitude faster than they do with conventional approaches.

Young children are significantly more likely than adults to have their opinions and decisions influenced by robots, according to new research. The study compared how adults and children respond to an identical task when in the presence of both their peers and humanoid robots.

HIV-1 replicates in ninja-like ways. The virus slips through the membrane of vital white blood cells. Inside, HIV-1 copies its genes and scavenges parts to build a protective bubble for its copies. Now, supercomputers have helped model a key building block in the HIV-1 protective capsid, which could lead to strategies for potential therapeutic intervention in HIV-1 replication.
