Scientists have identified and activated a small group of neurons responsible for the initiation of learned movements. The study used cutting-edge techniques to not only “read” brain activity down to the level of individual cells, but “write” patterns that allowed researchers to control movement.

A team of researchers headquartered at the University of Oklahoma is taking an innovative approach toward advancing grassland conservation and management, with grant support from the the U.S. National Science Foundation. The project brings together experts and observatory sites from across the state.

Perovskites, manufactured crystals used in solar cells, have long promised to boost solar power, but internal defects have blunted their potential. Now, researchers at Princeton Engineering have corrected the defects by adding a novel combination of chemicals during fabrication.

Physicist David Nolte is developing a laser-based"bio-dynamic" imaging system that could improve the care of cancer patients undergoing chemotherapy. Nolte's system can rapidly evaluate the outcome of different drugs on patient biopsies obtained during diagnosis to ensure patients get the chemotherapy treatment that would be most effective on their specific tumor.
