Preclinical trials are underway for a living-cell-based solution that would allow those with diabetes to avoid insulin injections. Previous trials of such implants have proved promising, but Encellin's new product takes the technology a step further by surrounding the insulin-producing cells with a porous membrane designed to prolong their life and eliminate the need for immunosuppressing drugs to prevent the patient's body from rejecting the cells.
CRISPR/Cas 9 technology is a kind of cut-and-paste technology used to edit genes, but it's a painstaking process and sometimes produces undesired results in the quest to cure diseases. Researchers at the Salk Institute for Biological Studies are suggesting a simpler and more predictable solution: using CRISPR instead as a switch to turn individual genes on and off.
Plastic tarps protect the strawberry crop outside Salinas, Calif., but they also amplify water runoff and erosion on hillside fields. The problem is exacerbated by recent heavy rains, sandy soil and the lack of county regulations to govern the situation.
Car tires and other rubber-based products made largely from fossil fuels may have a green future. Researchers at
University of Massachusetts Amherst have developed a way to using entirely green sources to make tires that are identical to current models by focusing on deriving isoprene, the key tire ingredient, from things such as trees and grass.
A robot developed in Singapore closely mimics the efficient swimming motion of a manta ray with flexible fins that work in fluid coordination with the water. Fin flexibility is key to the robot's speedy movement, allowing it to travel about twice its body length every second.
A loss of radar contact with a fishing boat and subsequent unconventional maneuvers intended to avoid impact led to a collision, the Navy says of the May 9 incident involving the guided-missile cruiser USS Lake Champlain. The collision occurred in the Sea of Japan.
Raytheon will be providing an Army-Navy Joint Electronic Type Designation System radar for a new Arleigh Burke-class destroyer under a contract valued at more than $48.6 million. The radar, deployed on cruisers and destroyers, supports the Aegis Ballistic Missile Defense System on land and at sea.
Virginia-based Leidos will provide support for a Navy and Marine Corps signature silencing program for surface ships and undersea systems. The $41.9 million contract applies to the Southeast Alaska Measurement Facility, the Navy's only West Coast facility that takes "high fidelity passive acoustic signature measurements."
Improvements in silent operation and maneuverability were among the reasons for several design updates in Russia's latest Project 955A "Borey-A" nuclear-powered ballistic missile submarine. The newest sub in the program, the Knyaz Vladimir, was officially launched Nov. 17, with delivery to the Russian navy set for next year.
General Dynamics Electric Boat is teaming with the University of Connecticut and the University of Rhode Island to research undersea vehicle technologies and offer related training. The National Institute for Undersea Vehicle Technology at UConn's Avery Point campus in Groton, Conn., "could be like the Silicon Valley for underwater activities," co-director Arun Shukla said.
