Bacteria hijack host cell process, create their own food supply to become infectious
Bacteria that cause the tick-borne disease anaplasmosis in humans create their own food supply by hijacking a process in host cells that normally should help kill the pathogenic bugs, scientists have found.
Seeing stars, finding nukes: Radio telescopes can spot clandestine nuclear tests
In the search for rogue nukes, researchers have discovered an unlikely tool: astronomical radio telescopes.
Alpine glacier, unchanged for thousands of years, now melting
Less than 20 miles from the site where melting ice exposed the 5,000-year-old body of Ötzi the Iceman, scientists have discovered new and compelling evidence that the Italian Alps are warming at an unprecedented rate.
Arctic cyclones more common than previously thought
From 2000 to 2010, about 1,900 cyclones churned across the top of the world each year, leaving warm water and air in their wakes—and melting sea ice in the Arctic Ocean.
Your body doesn't lie: People ignore political ads of candidates they oppose
