Cancer patients sometimes neglect to take the pills they need to fight their disease, but University of Minnesota researchers have developed a way to remind them and keep track of timing and dosages. Sensors embedded in each pill signal wearable receiver patches that, in turn, relay the information to the patient's smartphone and the physician's medical records.

Florida Polytechnic University used a $46,000 NATO grant to buy a 3D printer that can produce continuous carbon fiber-reinforced polymer shells that can withstand the intense pressure of nuclear radiation detectors. The high-strength material will allow researchers to improve the efficiency and portability of ionization detectors, says grant winner Robert Austin, a physics professor.
