Mark Crawford explores a number of applications where robots are helping healthcare practitioners, including bone surgery, senior care, exoskeletons and needle insertion. He also looks ahead to the cellular level where research is advancing on nano-robots.
Research led by scientists at MIT may lead to the creation of materials with properties such as insulation, conductivity and magnetic polarity that can be turned on and off in a trillionth of a second. The possibility stems from a discovery that extremely rapid pulses of light can activate a phase in metal oxide that gives it the ability to separate positive and negative charges.
Drones have advanced from inspecting power lines to assisting in their construction. On a project in the Fargo, N.D., area, SkySkopes drones pulled a rope through a pulley that in turn was attached to electricity-transmitting wires.

Bath Iron Works will be providing lead yard services for the Navy's DDG 51-class destroyers under a $61.6 million contract modification. Work will include engineering support and configuration, baseline upgrades and support for new technology, as well as acceptance trials.
General Dynamics Land will produce two MK46 modification 2 gun weapons systems for littoral combat ships and San Antonio-class landing platform dock ships under a new $25.6 million contract. The systems, as well as spare parts, will go aboard the future Robert M. McCool Jr. and the planned LPD-30.
A House Armed Services subcommittee is pressing the Pentagon to prioritize energy efficiency by, among other measures, taking another Navy look at hybrid electric drive systems for Arleigh Burke-class guided-missile destroyers. "The committee understands that hybrid electric drive propulsion systems operate with greater efficiency and facilitate greater range and on-station time," the committee mark on the subject states.
The Navy has scheduled a public meeting for Tuesday in Newport News, Va., as it considers options for disposing of the former USS Enterprise, a nuclear-powered aircraft carrier. The Navy is considering four options and aiming to make a decision by late 2022.
