Trending: Harvard's soft exosuit, a wearable robot, lowered energy expenditure in healthy people walking with a load on their back by almost 23% compared to walking with the exosuit powered-off. Such a wearable robot has potential to help soldiers and workers, as well as patients with disabilities.

EnvironmentSea level in the Northeast and in some other US regions will rise significantly faster than the global average, according to a new report. In a worst-case scenario, global sea level could rise by about 8 feet by 2100. The report lays out 6 scenarios intended to inform national and regional planning.
