A new study has found that most adults, everywhere in the world, are playing host to face mites. They live in our hair follicles, eat the oils we secrete, mate with each other near the surface of our skin, and sometimes venture out at night.

A bacterium previously unknown to science was found in two spacecraft clean rooms, one in Florida and the other in Guiana. Space agencies use these rooms to prepare spacecraft for launch and are considered two of the most sterile places on Earth.

Peter Diamandis makes a case for optimism -- that we'll invent, innovate and create ways to solve the challenges that loom over us. "I'm not saying we don't have our set of problems; we surely do. But ultimately, we knock them down."

Fasting is a practice that has been followed by various cultures and religions for centuries. It involves abstaining from food and, in some cases, beverages for a defined period. While fasting can have several physical and mental benefits, it is not uncommon for individuals to notice an unpleasant odor in their breath during fasting periods. Let's explore the reasons behind this phenomenon and uncover the science behind why one's breath may smell when they've fasted.

When we fast or restrict our carbohydrate intake for an extended period, our body undergoes a metabolic state called ketosis. During ketosis, the body shifts its primary source of energy from glucose (derived from carbohydrates) to ketones, which are produced when the liver brea ...

Bdellovibrio bacteriovorus is a bacterium that attacks other bacteria. It can charge its prey at speeds of up to 100 micrometers per second, comparable to a human running 600 kilometers per hour. It then bores into its hapless victim by spinning at 100 revolutions per second. Most bacteria aren't quite that fast, but they can move by whipping flagella or by spiraling through their environment.

Biologists from James Cook University have discovered a new species of leaf-tailed gecko in Australia. The lizard is highly camouflaged against the granite boulders it lives on and grows to around 12 cm. It's been named the Cape Melville leaf-tailed gecko (Saltaurius eximius) after the region in northern Queensland where it was found.

While this little guy may look like some sort of 'Hummingbee' it's actually a Bee Fly. They sneak their eggs into beehives, where their larvae can parasitize bee larvae and eat their food reserves!
