Physicists Detect Gravitational Waves, Proving Einstein Right - The New York TimesIf replicated by future experiments, that simple chirp, which rose to the note of middle C before abruptly stopping, seems destined to take its place among the great sound bites of science, ranking with Alexander Graham Bell’s “Mr. Watson — come here” and Sputnik’s first beeps from orbit.
Brain has internal ‘odometer’ and ‘stopwatch’To prove the contrary, researchers put rats on treadmills and recorded the activity of grid cells, keeping either distance or duration of running unchanged, and only varying the speed. As a result, 92% of grid cells in rats emitted signals at specific moments: for instance, one cell would fire 8 seconds into the run, not taking into account speed or distance covered, and another cell would emit a signal every 400 cm, not depending on speed or duration of the run. 50 percent of the cells were affected by distance, another half by time, and around 40 percent by both factors. "Space and time are ever-present dimensions by which events can be organized in memory," senior study author Howard Eichenbaum, a psychologist and neuroscientist at Boston University, said in the official press release.

Our guide explained that the horses, despite being extraordinarily intelligent beings, had a hard time making sense of seeing their friends appear out of nowhere, then disappear into the distance. Falling out of sight held the terror of being forever lost. My horse was calling out, making sure his friend was still there – that neither was lost. Underneath the geographic disorientation, one can imagine, lies a primal fear of losing control.
"We've taken pictures of both the doughnut and jelly parts, and the got the first data on the composition of the jelly yesterday. "It's like nothing we've ever seen before," he said. "It's very high in sulphur, it's very high in magnesium, it's got twice as much manganese as we've ever seen in anything on Mars. "I don't know what any of this means. We're completely confused, and everyone in the team is arguing and fighting (over what it means).
