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.

Before I begin telling you about this fascinating new glue (adhesive), there's a thing or two you need to know about the animal that inspired it all, the gecko. Geckos are small lizards that have the ability to run up walls and scurry across ceilings with the help of tiny rows of hairs on their feet known as setae. Setae generate a multitude of weak attractions (called Van der Waals forces) between molecules on the two surfaces that add up to a secure foothold. Unlike glue or tape, a gecko’s sticky feet attach and detach effortlessly, which made it a perfect case study for engineers to model.

To create their artificial gecko adhesive, a Stanford team of scientists started by making silicone micro-wedges, which imitated gecko hair. They asse ...

Listeria bacteria has been enlisted by researchers to selectively infect metastatic pancreatic cancer cells and deliver radioisotopes into them. The experimental treatment dramatically decreased the number of metastases (cancers that have spread to other parts of the body) in a mouse model of highly aggressive pancreatic cancer without harming healthy tissue. Mice livers are shown above. The saline control liver on the left presents a large number of metastases compared to the liver on the right which was subject to the radioactive Listeria treatment. ...

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!
