A nationwide chorus is urging the wearing of homemade face masks in public to fight the spread of the novel coronavirus. One voice is that of is physicist Walt de Heer who here explains some of the logic behind wearing the protective covering, starting with old-fashioned wisdom. “Your mother told you to cover your mouth when you cough, and this…
A simple, low-cost ventilator based on the resuscitation bags carried in ambulances – and widely available in hospitals – has been designed by an international team of university researchers. The device, which is powered by a 12-volt motor, could help meet peak medical demands in the industrialized world and serve resource-constrained countries…
Stepping off of the elevator on the first floor at 6 Executive Park in Atlanta, the first thing you notice about the space is its serenity. It’s light-filled, with lots of plants, a flowing water feature, and a neutral color palette – shades of soft blue, grey, beige, and sage green. It’s relaxed and welcoming, and that’s by design. The…

In January 2014, the Georgia Institute of Technology, Udacity and AT&T teamed up to launch the first Master of Science in Computer Science degree from an accredited university that students could earn exclusively through the "massive online" format. This collaboration—informally dubbed "OMS CS"—brings together leaders in education, MOOCs and…
A room-temperature bonding technique for integrating wide bandgap materials such as gallium nitride (GaN) with thermally conducting materials such as diamond could boost the cooling effect on GaN devices and facilitate better performance through higher power levels, longer device lifetime, improved reliability, and reduced manufacturing costs. The…
Some 20 percent of breast cancer survivors will suffer from lymphedema, a potentially severe side effect of treatment that makes arms swell with lymph. The disease is often overlooked, but commercially available app-based technology now makes early detection easier, allowing for proactive treatment. The lymphedema monitoring technology originated…
