Researchers at Georgia Tech built a system called SAIL to help robots trained by imitation learning move faster than the human demonstrations they learned from. Imitation learning means robots copy actions shown by people, but they usually cannot go faster than the demonstrations.
SAIL has several parts that keep motion smooth, track movement, change speed when a task is hard, and plan actions to handle hardware delays. The team tested SAIL on several tasks such as stacking cups, folding cloth and plating fruit. In many cases, robots finished tasks several times faster without losing accuracy, but wiping a whiteboard was harder at high speed.

Researchers at Yale found a human antibody that blocks epiregulin and lowers fibrosis markers. They also show EGFR activates STAT1 in fibroblasts, suggesting two treatment paths: block epiregulin or target the EGFR–STAT1 pathway.
