In 2004, pediatric audiologist Allyson Sisler-Dinwiddie plunged into a world of silence after a car accident damaged her hearing. Under the care of hearing researcher Rene Gifford, she became one of the first test subjects of a new technique to improve cochlear implants, devices that use electrodes to stimulate cells in the inner ear. Since then, Sisler-Dinwiddie and Gifford have worked together to restore other patients' hearing. Watch the pair and their team at Vanderbilt University as they develop a resounding remedy to help people hear again.

Peregrine falcons catch other birds mid-flight by diving at more than 200 mph. To do it, they need some high-precision gear: special eyesight, talons and aerodynamics that can't be beat.

---

While known for being the world’s fastest bird–peregrines have been clocked at diving more than 200 miles per hour–these majestic birds were at risk for going extinct 50 years ago. Widespread use of pesticides such as DDT decimated native populations of peregrine falcons.

By 1970, California’s peregrine population had dwindled to only two known nesting pairs statewide. The federal government banned DDT in 1972. And successful restoration efforts spearheaded by organizations like The Peregrine Fund helped revive their numbers. By 1999, they were removed from the federal Endangered Species List. Recent surveys estimate that there are now 300 to 350 nesting pairs in California and more than 2400 pairs nationwide.

--- What’s the origin of the Peregrine Falcon's name?
Peregrine is Latin for "Peregrinus," which means “traveler” or “pilgrim.”

--- How many eyelids do raptors, or birds or prey, like peregrine falcons have?

They have three! Two eyelids are used for closing their eyes, while the third is used for blinking. It’s also called the nictitating membrane and helps to protect their eyes and keep them moist and clean. It’s semi-transparent, so they can actually still see through it when it’s closed.

--- Did you know they have a special bone to protect their eyes?

It’s called a sclerotic ring and helps support and secure their eyeballs within their skulls.

You may think that you've got the house to yourself, but chances are you have about 100 different types of animals living with you. Many of them are harmless, but a few can be dangerous in ways you wouldn't expect. New research explores exactly whom you share your home with and how they got there.

---+ About Dust Mites

With the warming weather it’s the season for spring cleaning. But before you reach for the broom and mop, take a moment to look at who else is sharing your home with you. The number of uninvited guests you find in your dustpan may surprise you.

A recent study published in the journal PeerJ took up the challenge of cataloging the large numbers of tiny animals that live in human dwellings. The researchers found that the average home contains roughly 100 different species of arthropods, including familiar types like flies, spiders and ants, but also some kinds that are less well known like gall wasps and book lice. And no matter how much human residents may clean, there will always be a considerable number of mini-roommates.

“Even as entomologists we were really surprised. We live in our houses all the time, so we thought we’d be more familiar with the kind of things we’d come across. There was a surprising level of biodiversity,” said Michelle Trautwein, assistant curator of entomology at the California Academy of Sciences in San Francisco.

---+ What are dust mites?

Dust mites are tiny animals, related to spiders, that are usually too small to be seen with the naked eye. They feed on dead skin that humans shed every day and their droppings may cause allergic reactions and may aggravate asthma, especially in children.

---+ How do you minimize dust mites?

It’s practically impossible to completely rid a home of dust mites, but frequent cleaning and removing carpeting can help. Wet cleaning like mopping helps keep from stirring up dust while cleaning. The most effective way to keep dust mite populations down is to keep the indoor humidity level low. Dust mites can only survive in humid environments.

---+ How do you see dust mites?

Dust mites are about .2mm long. You can see dust mites with a powerful magnifying glass, but you can get a better view by using a microscope.

The glow worm colonies of New Zealand's Waitomo Caves imitate stars to confuse flying insects, then trap them in sticky snares and eat them alive.

SUBSCRIBE to Deep Look! http://goo.gl/8NwXqt

DEEP LOOK is science up close - really, really close. An ultra-HD (4K) short video series created by KQED San Francisco and presented by PBS Digital Studios. See the unseen at the very edge of our visible world. Get a new perspective on our place in the universe and meet extraordinary new friends. Explore big scientific mysteries by going incredibly small.

Like fireflies, the spectacular worms of New Zealand’s Waitomo Caves glow by breaking down a light-emitting protein. But unlike the yellow mating flashes of fireflies, the glow worms’ steady blue light has a more insidious purpose: it’s bait.

The strategy is simple. Many of the glow worms’ prey are insects, including moths, that navigate by starlight. With imposter stars all around, the insects become disoriented and fly into a waiting snare. Once the victim has exhausted itself trying to get free, the glow worm reels in the catch.

The prey is typically still alive when it arrives at the glow worm’s mouth, which has teeth sharp enough to bore through insect exoskeletons.

Glow worms live in colonies, and researchers have noticed that individual worms seem to sync their lights to the members of their colony, brightening and dimming on a 24-hour cycle. There can be several colonies of glow worms in a cave, and studies have shown that different colonies are on different cycles, taking turns at peak illumination, when they’re most attractive to prey.

Not surprisingly, the worms glow brighter when they’re hungry.

--- How do glow worms glow?

Their light is the result of a chemical reaction. The worms break down a protein called luciferin using an enzyme, luciferase, in a specialized section of their digestive tract. The glow shines through their translucent skin.

--- Why do glow worms live in caves?

The glow worms need to be in a dark environment where their light can be seen. Caves also shelter them from the wind, which can tangle their dangling snares.

--- Where can I see glow worms?

The Waitomo Caves are on New Zealand’s North Island. Other New Zealand glow worm sites include the Te Anau caves, Lake Rotoiti, Paparoa National Park, and Waipu. A related species inhabits similar caves in eastern Australia.

Why can't you just flick a tick? Because it attaches to you with a mouth covered in hooks, while it fattens up on your blood. For days. But don't worry – there *is* a way to pull it out.

DEEP LOOK: a new ultra-HD (4K) short video series created by KQED San Francisco and presented by PBS Digital Studios. See the unseen at the very edge of our visible world. Explore big scientific mysteries by going incredibly small.

Spring is here. Unfortunately for hikers and picnickers out enjoying the weather, the new season is prime time for ticks, which can transmit bacteria that cause Lyme disease.

How they latch on – and stay on – is a feat of engineering that scientists have been piecing together. Once you know how a tick’s mouth works, you understand why it’s impossible to simply flick a tick.

The key to their success is a menacing mouth covered in hooks that they use to get under the surface of our skin and attach themselves for several days while they fatten up on our blood.

“Ticks have a lovely, evolved mouth part for doing exactly what they need to do, which is extended feeding,” said Kerry Padgett, supervising public health biologist at the California Department of Public Health in Richmond. “They're not like a mosquito that can just put their mouth parts in and out nicely, like a hypodermic needle.”

Instead, a tick digs in using two sets of hooks. Each set looks like a hand with three hooked fingers. The hooks dig in and wriggle into the skin. Then these “hands” bend in unison to perform approximately half-a-dozen breaststrokes that pull skin out of the way so the tick can push in a long stubby part called the hypostome.

“It’s almost like swimming into the skin,” said Dania Richter, a biologist at the Technische Universität Braunschweig in Germany, who has studied the mechanism closely. “By bending the hooks it’s engaging the skin. It’s pulling the skin when it retracts.”

The bottom of their long hypostome is also covered in rows of hooks that give it the look of a chainsaw. Those hooks act like mini-harpoons, anchoring the tick to us for the long haul.

“They’re teeth that are backwards facing, similar to one of those gates you would drive over but you're not allowed to back up or else you'd puncture your tires,” said Padgett.

--- How to remove a tick.
Kerry Padgett, at the California Department of Public Health, recommends grabbing the tick close to the skin using a pair of fine tweezers and simply pulling straight up.

“No twisting or jerking,” she said. “Use a smooth motion pulling up.”

Padgett warned against using other strategies.

“Don't use Vaseline or try to burn the tick or use a cotton swab soaked in soft soap or any of these other techniques that might take a little longer or might not work at all,” she said. “You really want to remove the tick as soon as possible.”

--- What happens if the mouth of a tick breaks off in your skin?
Don’t worry if the tick’s mouth parts stay behind when you pull.

“The mouth parts are not going to transmit disease to people,” said Padgett.

If the mouth stayed behind in your skin, it will eventually work its way out, sort of like a splinter does, she said. Clean the bite area with soap and water and apply antibiotic ointment.

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.

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 thumb-like part called a spine. With the claw and spine at the end of each of its six legs, a louse grasps a hair strand to hold on, or quickly crawl from hair to hair like a speedy acrobat.

Their drive to stay on a human head is strong because once they’re off and lose access to their blood meals, they starve and die within 15 to 24 hours.

--- How do you kill lice?
Researchers found in 2016 that lice in the U.S. have become resistant to over-the-counter insecticide shampoos, which contain natural insecticides called pyrethrins, and their synthetic version, known as pyrethroids.

Other products do still work against lice, though. Prescription treatments that contain the insecticides ivermectin and spinosad are effective, said entomologist John Clark, of the University of Massachusetts, Amherst. They’re prescribed to kill both lice and their eggs. Clark said treatments such as suffocants, which block the lice’s breathing holes, and hot-air devices that dry them up, also work. He added that tea tree oil works both as a repellent and a “pretty good” insecticide. Combing lice and eggs out with a special metal comb is also a recommended treatment.

--- How long do lice survive?
It takes six to nine days for their eggs to hatch and about as long for the young lice to grow up and start laying their own eggs. Adult lice can live on a person’s head for up to 30 days, according to the Centers for Disease Control and Prevention (CDC).

--- Can your pet give you lice?
No. Human head lice only live on our heads. They can’t really move to other parts of our body or onto pets.
