We know we got here from somewhere, but who would have suspected it was by way of a fish that used electrical currents to hunt and communicate and locate itself?
Three simple numbers that add up to global catastrophe – and that make clear who the real enemy is
Here you are, a human being, a grand Universe of atoms that have organized themselves into simple monomers, assembled together into giant macromolecules, which in turn comprise the organelles that make up your cells. And here you are, a collection of around 75 trillion specialized cells, organized in such a way as to make up…
Polar and brown bears diverged between 4 million and 5 million years ago, but they continued to interbreed when the climate warmed. Now, there is evidence that it is happening again.
A prediction: When all the votes have been counted and the reams of polling data have been crunched, analyzed, and spun, this will be clear: Few scientists will have voted for Republican candidates, particularly for national office. Survey data taken from 1974 through 2010 and analyzed by Gordon Gauchat in the American Sociological Review confirm…
New research indicates that life might be able to survive on some of the odder exoplanets discovered so far – from scorching hot worlds with molten surfaces to freezing balls of ice. Habitable planets are usually defined as those where liquid water can exist. But not all exoplanets orbit, like Earth, at a fairly constant…
Within supersized alien versions of Earth, a common transparent ceramic may become a flowing liquid metal, perhaps granting those distant worlds magnetic fields to shield life from harmful radiation, researchers say. Among the hundreds of extrasolar planets, or exoplanets, that astronomers have discovered in recent years are so-called “super-Earths,” which are rocky planets like Earth…
