New robot rolls with the rules of pedestrian conduct

Approach may enable robots to move around hospitals, malls, and other areas with heavy foot traffic BY JENNIFER CHU, MIT NEWS  CAMBRIDGE, Mass. — Just as drivers observe the rules of the road, most pedestrians follow certain social codes when navigating a hallway or a crowded

Researchers clarify mystery about proposed battery material

Study explains conflicting results from other experiments, may lead to batteries with more energy per pound BY DAVID L CHANDLER, MIT NEWS CAMBRIDGE, Mass. — Battery researchers agree that one of the most promising possibilities for future battery technology is the lithium-air (or lithium-oxygen) battery,

Lunar dynamo’s lifetime extended by at least 1 billion years

Findings suggest two mechanisms may have powered the moon’s ancient churning, molten core BY JENNIFER CHU, MIT NEWS CAMBRIDGE, Mass. — New evidence from ancient lunar rocks suggests that an active dynamo once churned within the molten metallic core of the moon, generating a magnetic field
