An amateur astronomer has picked up signals from a satellite NASA gave up for dead more than decade ago.

Scott Tilley was scanning the skies for secret military satellites when he picked up a transmission from the Imager for Magnetopause-to-Aurora Global Exploration (IMAGE) satellite.

The World Health Organization has called antibiotic resistance “a global crisis we can’t ignore,” one that the Centers for Disease Control and Prevention estimate kills 23,000 people annually in the U.S. alone.

Now, honeybee research could offer clues as to how it spreads.

Alternative energy sources like wind offer a way to lessen a country’s carbon footprint. But global warming trends could soon change the way the wind blows.

As rapid arctic warming shrinks the heat gap between the North Pole and equator, Northern Hemisphere winds could lose some oomph — up to 40 percent over the next century, depending on region.
