True’s beaked whale sightings are so rare, that scientists who devote careers to studying these animals may never actually witness one swimming in the wild.
But thanks to an international team of scientists that compiled True’s beaked whale sightings, we can all watch the first underwater video of True’s beaked whales swimmi ...read more
A system that interprets brain signals enables human operators to correct the robot’s choice in real-time. Credit: Jason Dorfman, MIT CSAIL
Baxter the robot can tell the difference between right and wrong actions without its human handlers ever consciously giving a command or even speaking a word. The robot’s learning success relies upon a system that interprets the human brain’s “oops” signals to let Baxter know if a mistake has ...read more

When an oil tanker runs aground or a deep-sea well suffers a leak, millions of gallons of oil can flood into the ocean. Once there, oil slicks can be tremendously difficult to contain, and pose risks to ocean-dwellers and coastlines when they wash ashore in waves of sticky sludge.[embedded content]
Normal containment measures involve burning or skimming the thin layer of oil off of the surface, but these aren’t perfect and pose their own risks. Materia ...read more
What happens in the brain when we die?
Canadian researchers Loretta Norton and colleagues of the University of Western Ontario examine this grave question in a new paper: Electroencephalographic Recordings During Withdrawal of Life-Sustaining Therapy Until 30 Minutes After Declaration of Death
Norton et al. examined frontal EEG recordings from four critically ill patients at the point where their life support was withdrawn. Here are some details on the four:
Here’s the EEG recordings. No ...read more
