bacteria

They don't have wings, but bacteria sure can fly. Researchers at MIT say that tiny bubbles trapped by raindrops play a part in launching bacteria on long-distance flights.

For the first time, the World Health Organization has released a list of 12 bacteria that "pose the greatest threat to human health" because of their antibiotic resistance.

Ten thousand years ago, many of our deadly human diseases didn't exist. What happened?

Scientists were shocked to see what happened when this ancient bacterium encountered modern antibiotics.

Manufacturers didn't provide data showing the chemicals are safe and effective, the FDA says. It says there's no evidence that they do a better job at preventing illness than plain soap and water.

Think of it as a gift within a gift. Some beneficial gut bacteria contain viruses called "bacteriophages." And some of these phages now have been associated with good intestinal health in humans.

Scientists have found the first eukaryotic organism that functions fine without mitochondria, the "powerhouses" that make energy for the cells of yeast, humans and other animals.

It's not the tick that causes Lyme disease, but the bacteria that live in its spit. Scientists at the Mayo Clinic have found a second bacterium capable of causing the disease in people.

It causes melioidosis, whose yearly death toll of 90,000 is about the same as for measles. But the disease hasn't been on the global health radar — until now.

You're not just shedding microbes on every surface you touch. Research suggests you're actually walking around in an airborne plume of bacteria and other microscopic organisms that's unique to you.

The relationship between the types of microbes in our gut and belly fat is turning out to be a lot more complicated than scientists first thought.
