Thanks to BCI, physically impaired persons can control special prostheses through the power of their minds, surf in internet and write emails. Under the title of "Brain Composer," a group led by BCI expert Gernot Müller-Putz from TU Graz's Institute of Neural…

Much later - perhaps as many as one billion years after the Big Bang - the universe expanded, became more transparent, and eventually filled up with galaxies, planets, stars, and other objects that give off…

Plants and brains are more alike than you might think. Salk scientists discovered that the mathematical rules governing how plants grow are similar to how brain cells sprout connections. In particular, plants use the same rules to grow under widely different conditions (for example, cloudy versus sunny) and the density of branches in space follows…
