A powerful jet from a super massive black hole is blasting a nearby galaxy, according to new findings from NASA observatories. This never-before witnessed galactic violence may have a profound effect…

Researchers at the University of California, Berkeley, have successfully generated electricity from heat by trapping organic molecules between metal nanoparticles, an achievement that could pave the…

Imagine two stars with winds so powerful that they eject an Earth's worth of material roughly once every month. Next, imagine those two winds colliding head-on. Such titanic collisions produce…

An international team of researchers from 19 countries has identified one gene and a previously unidentified region of another chromosome as the location of another gene that may contribute to a…

Though the cell membrane is a protective barrier, it also plays a role in letting some foreign material in — via ion channels that dot the cell’s surface. Now new research from the Nobel Prize…

Hunting for traces of life on Mars calls for two radically different strategies, says Arizona State University professor Jack Farmer. Of the two, he says, with today’s exploration technology we can…
