Pizza ovens need to run all day long at 500 degrees Fahrenheit, but no more than 10% of the energy used actually goes to baking pizzas. Now James Cotton, professor of mechanical engineering and associate director of Canada's McMaster University Institute for Energy Studies, has developed a way to capture that wasted energy and use it to generate electricity with a chimney-based system that consists of a heat exchanger, a cooling loop and thermal storage.
Technology holds great promise for simplifying the methodologies behind cancer-fighting T cell therapy, allowing for greater consistency and scalability in cell manufacturing. That's according to Patrick Hanley, director of the Good Manufacturing Practices (GMP) cellular therapy laboratory at Children's National Health System, who reflects on progress in the field in an interview.
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.
A recent simulation found that artificial intelligence can help determine effective interviewing techniques but doesn't comprehend which leadership behaviors are most productive, writes Mengqiao Liu of DDI. The best uses for AI at the moment are in automating certain tasks and leveraging data, Liu writes.
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.
