Augmented and virtual reality are adding significantly to the ability of bioengineers and surgeons to understand and share what they can learn about human anatomy, with the goal of improving devices and procedures. Mark Crawford explores how one technology in this field, Microsoft's HoloLens, is being used to provide fresh insights.
Technology that would allow electric vehicles to not only charge up from the grid but also return stored power to the grid as needed has been touted for years now but fails to show up. The benefits could be enormous for aging electrical grids, but a number of issues remain to be addressed, including the wear and tear on EV batteries and determining responsibility for associated costs as well as electricity trading.

General Dynamics will be repairing the engine and addressing other maintenance tasks on the USS Mesa Verde under a $15.2 million contract. Work on the San Antonio-class amphibious transport dock is scheduled for Norfolk, Va., and should be completed by May of next year.
Additional long lead time material for steam, electric plant and other components is the subject of a $696 million fee modification to a previous contract awarded to General Dynamics Electric Boat for Virginia-class submarines.
The Navy has chosen Gulf Island Shipyards for a $63.5 million contract covering design and construction services for the towing, salvage and rescue ship. The T-ATS will eventually replace the Safeguard class of salvage and rescue ship and the Powhatan-class fleet ocean tug.
Annie Mabus, daughter of former Navy Secretary Ray Mabus, presided as the USS Colorado, the Navy's latest attack submarine, joined the fleet in ceremonies at Groton, Conn.

The Navy is seeking further information on potential cost savings from Huntington Ingalls Industries as it considers whether to place an order for two aircraft carriers rather than one. The potential for significant savings must be proved, said James Geurts, assistant secretary of the Navy for research, development and acquisition.
