![]() ![]() The scientists began with a surface that strongly repelled both water and oil. This new technique, developed by an international team of researchers, can transport tiny drops of liquid faster and farther than other methods. Thankfully, the laws of physics remain intact: the droplets are stuck to an invisible path of charged atoms. ![]() Daredevil Droplets Credit: City University of Hong Kongįreely rolling uphill and upside down, these water droplets seem to break basic rules of nature. It helped that their subject, a brain donated to science by a 58-year-old woman who died of viral pneumonia, could stay perfectly still.Īlthough this GIF gives a beautiful representation, it doesn’t do justice to the original images. They scanned the brain for 100 hours-from top to bottom, side to side and front to back. To get their resolution down to a tenth of a millimeter, researchers at Massachusetts General Hospital used a magnetic resonance imaging (MRI) machine with a superstrong seven-tesla magnet (typical MRI magnets are only 0.5 to three teslas). Slice by slice, these images of a human brain are perhaps the clearest ever produced. Posted to Dryad Digital Repository on June 4, 2019 ![]()
