Machine-learning system determines the fewest, smallest doses that could still shrink brain tumors In an effort to improve the quality of life for patients by reducing toxic chemotherapy and radiotherapy dosing for glioblastoma, the most aggressive form of brain cancer, MIT researchers are employing novel machine-learning techniques. According to the team, glioblastoma is a malignant tumor ... » read more

Sensing without battery power Engineers at the National University of Singapore developed an IoT-focused sensor chip that can continue operating when its battery runs out of energy. The chip, BATLESS, uses a power management technique that allows it to self-start and continue to function under dim light without any battery assistance. The chip can operate in two different modes: minimum-ene... » read more

Carbon nanotubes “unzipped” into graphene nanoribbons by a chemical process invented at Rice University are finding use in all kinds of projects, but Rice scientists have now found a chemical-free way to unzip them. A Rice materials scientist discovered that nanotubes that hit a target end first turn into mostly ragged clumps of atoms, but nanotubes that happen to broadside the target un... » read more

Better Beer Rice University has devised a polymer material that could boost the properties of natural gas, beer and soda. By adding modified, single-atom-thick graphene nanoribbons (GNRs) to thermoplastic polyurethane (TPU), Rice’s polymer material could make it more practical for vehicles to run on compressed natural gas. The material is far more impermeable to pressurized gas and lighte... » read more
