Lack of quality demographic data is a major obstacle to planning infrastructure in the developing world. In a recent study, a team of researchers from the Santa Fe Institute in the U.S., the University of Manchester in the U.K., and the Université Cheikh Anta Diop in Senegal used anonymized cell phone data to assess the feasibility of electrification options for rural communities in Senegal.

Using a weak electric current to alter a specific brain activity pattern, UNC School of Medicine researchers increased creativity in healthy adults. Now they’re testing the same experimental protocol to alleviate symptoms in people with depression.

Researchers from Columbia Engineering and the Georgia Institute of Technology have reported the first experimental observation of piezoelectricity and the piezotronic effect in an atomically thin material, molybdenum disulfide (MoS2), resulting in a unique electric generator and mechanosensation devices that are optically transparent, extremely light, and very bendable and stretchable.
