Electricity distribution systems in the USA are gradually being modernized and transposed to smart grids, which make use of two-way communication and computer processing. This is making them increasingly vulnerable to cyber attacks. In a recent paper in Elsevier's International Journal of Critical Infrastructure Protection, Dr. Sujeet Shenoi and his colleagues from the Tandy School of Computer Science, University of Tulsa, US, have analyzed these security issues.

Nanoengineers at the University of California San Diego have demonstrated for the first time using micromotors to treat a bacterial infection in the stomach. These tiny vehicles, each about half the width of a human hair, swim rapidly throughout the stomach while neutralizing gastric acid and then release their cargo of antibiotics at the desired pH.

With cyberattacks on 3-D printers likely to threaten health and safety, researchers at Rutgers University-New Brunswick and Georgia Institute of Technology have developed novel methods to combat them, according to a groundbreaking study.

An article published online August 3, 2017 by Brain reports a novel mapping methodology adapted for stroke brains at the Medical University of South Carolina. Researchers combined connectome-lesion symptom mapping with traditional voxel-based cortical lesion symptom mapping to assess brain networks supporting auditory comprehension. Results confirm the middle, inferior and posterior temporal regions are the most important for speech comprehension and shed light on potential contributions of temporal lobe network connections in understanding spoken language.
