T cells engineered to fight a patient's cancer can also sometimes damage healthy organs. To address this problem, researchers are working on a system that uses ultrasound to allow remote control of T cell genetic processes and prompts them to recognize and destroy only cancer cells.
Taking up the mission of defending Earth from the devastation of an asteroid strike, NASA envisions an 8.8-ton spacecraft with enough velocity and mass to deflect the menacing rock before it can reach its target. And if that's deemed insufficient, the Hypervelocity Asteroid Mitigation Mission for Emergency Response (HAMMER) craft could bring along a nuclear warhead.
DesiCorp is studying the role of the molecule trehalose in allowing animals such as sea monkeys to survive dehydration and rehydration, and whether it could be used to extend the shelf life of red blood cells. The biotech has used sound waves to place the molecule in red blood cells, and its most successful tests have resulted in rehydration of about 50% of dehydrated red blood cells.
Five ships, including the Ticonderoga-class guided-missile cruiser USS Antietam, participated in a surface-to-air missile exercise in the Philippine Sea as part of MultiSail 2018. The Antietam's role was crucial, "adding the cruiser point of view to the normally destroyer-focused Surface Action Group composition," said Lt. Mor Rosenberg, a warfare tactics instructor.
Reports of the demise of the Navy's railgun project are in error, Adm. John Richardson said, adding that the service is fully committed to the technology. Speaking before a House panel, Richardson said the gun had been tested over shorter distances and now must be engineered for ranges up to 100 miles and for faster firing rates.
A $21.5 million support contract awarded to Northrop Grumman for the Navy's laser weapon demonstrator project brings its total value to more than $144.9 million. The weapon is intended to eventually be deployed on ships to disable or destroy enemy ships as well as unmanned aerial vehicles or surveillance sensors.
The Navy submarines USS Connecticut and USS Hartford are being joined by the Royal Navy's HMS Trenchant in Ice Exercise 2018. The five-week exercise evaluates operational procedures in Arctic conditions.
The Navy plans to name its next destroyer after an Irish immigrant corporal in the Marine Corps who died in the Vietnam War. Cpl. Patrick Gallagher was awarded the Navy Cross for saving fellow Marines by diving onto a live grenade.
The USS Ralph Johnson is on its way from Ingalls Shipbuilding in Pascagoula, Miss., to South Carolina for commissioning this month. The ship is named after Marine Pfc. Ralph Henry Johnson, a Medal of Honor recipient who died in the Vietnam War at age 19 when he threw himself on a grenade to save his fellow Marines.
