But down at ground level, the pastoral scenery is concealing a surprising battle: relentless chemical warfare between bugs. More than 200 species of millipedes emerge from their und...

Porcupines may be adorable, but their quills are razor-sharp, designed to impale and next to impossible to remove. But it's not all bad news. Researchers are designing new surgical staples that mimic the quill's shape to better close wounds and speed up healing.

Explore big scientific mysteries by going incredibly small. The quills of North American porcupines have microscopic backward-facing barbs on the tips. Those barbs make the quills slide in easy but very difficult to remove. Researchers at Harvard are looking to porcupine quills for inspiration in designing a new type of surgical staple that would also use tiny barbs to keep itself lodged into the patie...

Why are itchy lice so tough to get rid of and how do they spread like wildfire? They have huge claws that hook on hair perfectly, as they crawl quickly from head to head.

See the unseen at the very edge of our visible world. Explore big scientific mysteries by going incredibly small. Head lice can only move by crawling on hair. They glue their eggs to individual strands, nice and close to the scalp, where the heat helps them hatch. They feed on blood several times a day. And even though head lice can spread by laying their eggs in sports helmets and baseball caps, the main way they get around is by simply crawling from one head to another using scythe-shaped claws. These claws, which are big relative to a louse’s body, work in unison with a small spiky...

They're imported agricultural pests eating their way across North America. But a native enemy from Asia – the tiny samurai wasp – has a particularly nasty method of stopping stink bugs in their tracks.

With a speckled exterior and a shield-like shape, the brown marmorated stink bug doesn’t appear to be any different from any other six-legged insect that might pop up in your garden. But this particular bug, which arrived in the U.S. from Asia in the mid-1990s and smells like old socks when it is squashed, is a real n...

They're packing some sophisticated equipment inside that squishy schnozz.

According to one estimate, dogs are 10,000-100,000 times more sensitive to smell than humans. They have about 15 times more olfactory neurons that send signals about odors to the brain. The neurons in a dog’s nose are spread out over a much larger and more convoluted area allowing them more easily decipher specific chemicals in the air. --- Why are dog noses wet? Dog noses secrete mucus which traps odo...

If you’re out on a hike and look down at a puddle, you might spot a long, brown spaghetti-shaped creature whipping around madly in a figure eight. It’s a hairworm – also known as a horsehair worm or Gordian worm – and researchers have described 350 species around the world. Good news: It isn’t interested in infecting or attacking humans. But if you had happened on the puddle a few hours earlier, you might have witnessed a gruesome spec...
