We already mimic them to make fly-fishing lures. But now scientists believe copycatting one tiny insect could hold promise for repairing human tissues and setting bones.

Instead of stitches and screws, doctors may soon call on the next generation of medical adhesives — glues and tape — to patch us up internally.

The inspiration? Caddisflies, a type of stream-dwelling, fish-baiting insects that live in creeks all across the United States.

As a larva, the caddisfly constructs a tiny tube-like house for itself, called a case, entirely underwater, using pebbles and its incredible homespun tape as the mortar.

Thanks to the qualities of this amazing silk, the case not only holds up when submerged, it is strong enough to protect the caddisfly’s soft lower body amid forces many times its body weight.

Any tape, including this one, has two basic components: the flat ribbon, or backing, and the layer of sticky stuff, or the glue. From the materials science standpoint, caddisfly tape is extraordinary in both departments.

Caddisfly silk biomimicry is only in its infancy, but one day, a similar compound might be used inside the body, which is another watery environment, to mend soft tissues and even repair hard ones, such as teeth and bone.

In the streambed, or brook, the caddisfly’s case eventually becomes a cocoon. Like its land-based cousins, the butterflies and moths, from whom it diverged 250 millions years ago, the caddisfly larva undergoes a metamorphosis. It seals up its case with a so-called “hat stone” and emerges months later as a winged adult.

--- Where do caddisflies live?

Caddisflies are most common in shallow, cold, turbulent streams, where the water is highly oxygenated.

--- What do caddisflies eat?

Caddisflies are herbivores, they eat decaying plant matter and algae on the rocks in the streams where they live.

--- What is so special about caddisfly silk?

Engineers are interested in two attributes of caddisfly silk. First of all, it can bond to something, such as a pebble, underwater, which no glue people have made can replicate. Second its “viscoelastic” properties allow to it harmlessly absorb physical forces. When stretched, it doesn’t snap back like a rubber band. It returns to its original shape slowly and safely. It's an engineering marvel.

Yep, you probably have Demodex mites living on your face. These tiny arachnids feast on sebum, the greasy oil in your pores. But should you be worried about your eight-legged guests?

Pretty much every adult human alive has a population of these mites living on them.

Also called eyelash mites, they’re too small to see with the naked eye. They’re mostly transparent, and at about .3 millimeters long, it would take about five face adult mites laid end to end to stretch across the head of a pin.

Face mites spend their days face-down inside your hair follicles nestled up against the hair shaft.
They eat sebum, that greasy oil your skin makes to protect itself and keep it from drying out. That’s why the greasiest parts of your body — like around the eyes, nose and mouth — likely harbor a higher concentration of mites than other areas.

They live about two weeks. They spend most of their time tucked inside our pores. But while we’re sleeping, they crawl out onto the surface of our skin to mate before crawling back into our pores to lay their eggs. Fun!

--- How common are face mites?
Pretty much everyone has some face mites on them. Babies are born without them but quickly receive them from their parents through direct contact. The amount of mites may increase during puberty when the skin starts to produce more oil.

--- How do you get rid of face mites?
There’s usually no need to try to rid yourself of face mites as they typically don’t cause any symptoms and are nearly impossible to fully eradicate. Since female face mites can also reproduce asexually, it only takes one mite to repopulate your skin. Some people experience an overpopulation of face mites resulting in an inflammatory disease called demodicosis which is easy to recognize sue to the many small evenly-sized pimples that appear quickly. Consult a dermatologist if you think you may have symptoms.

--- What do face mites eat?

Face mites consume the greasy oil that you skin produces to protect itself.

Turtles grow up without parents, which might sound lonely. But for threatened baby turtles raised in a zoo it’s an advantage: they can learn to catch crickets all by themselves. There’s a paradox, though. When they are ready to leave the nursery, there is little wilderness where they can make a home.

Where do turtles live?
Western pond turtles live most of their lives in the water, in freshwater lakes.


What do turtles eat?
The meat-eaters feed on crustaceans like crayfish, dragonfly nymphs and fish.


Are turtles reptiles?
Turtles are reptiles not amphibians. They are considered reptiles since they live in water.


Are turtles endangered?
"There are only 300 species, and most of them are doing quite poorly." The turtles haven’t been doing well in their native habitat in the western United States. In California, they’re a species of “special concern.”


Why can turtles be raised in zoos?
Most turtle species grow up without parents, which makes them easy to raise in zoos and help conservation. Once a female western pond turtle lays her eggs near a lake or pond, she never returns to the nest. Because they lack parental care, turtles don’t imprint on zoo keepers.

Take the PBSDS survey: https://to.pbs.org/2018YTSurvey

Fluffy kittens chasing a ball are beyond adorable -- but they sure aren't born that way. Practically deaf and blind, in their first few weeks they need constant warmth and milk to survive. This is a huge challenge for animal shelters, so they're working with researchers on ways to help motherless kittens flourish.

--

Every year, hundreds of thousands of kittens end up in animal shelters, in need of permanent homes.

But raising orphaned newborns into healthy, fluffy, frisky two-month-olds ready to be adopted requires an enormous behind-the-scenes effort. All across the country, volunteer foster parents log many sleepless nights bottle-feeding kittens every few hours. So researchers and shelters are trying to figure out ways to make it easier.

“A lot of people think fostering is taking kittens home and playing with them,” said Penny Dougherty, chief executive director of Kitten Central of Placer County, an animal shelter she runs from her house in Newcastle, California, 30 miles northeast of Sacramento.

Kitten Central receives most of its kittens from Placer County Animal Services. Dougherty cares for kittens up to one month old, as well as feral and stray cats with litters. Once the kittens weigh at least two pounds and have been spayed and neutered, she returns them to the agency so they can put them up for adoption.

“They’re very happy to have our services,” said Dougherty, “because so many shelters have to euthanize.”

When the days start getting longer, around January, cats start breeding. March is the beginning of what’s known among shelters as “kitten season.” The flow of kittens doesn’t slow down until November.

“Kitten season is kind of one of the banes of shelter existence,” said Cynthia Delany, supervising shelter veterinarian at Yolo County Animal Services, in Woodland, west of Sacramento. “Six or seven months out of the year we’re just flooded with these little guys.”

To steer clear of inundating shelters with newborn kittens, Delany’s advice is to leave any litters you might encounter alone unless they’re in immediate danger. Most of the time their mom will return, she said, so check back periodically.

In an effort to lessen the load on foster parents and increase newborn kittens’ chances of survival, Mikel Maria Delgado, a postdoctoral researcher in the School of Veterinary Medicine at the University of California, Davis, is joining forces with Kitten Central and other animal shelters to figure out if there are optimum temperature and humidity levels that make it possible to feed newborn kittens less frequently. She has distributed incubators to the groups so that two or three kittens can be kept in each one for about three weeks.

---How long do kittens' eyes stay closed?
During the first week-and-a-half of their lives, kittens’ eyes are sealed closed and their ears are folded up, making them practically blind and deaf. They’re born this way because their brains aren’t developed enough to use those senses.

"Come Together" Lyrics:

Here we are with our backs against the wall
We've got Big city dreams but we don't move from the asphalt
We run away from our own imagination
But at the same time we've got this amazing fascination

We've got hopes on the horizon
And we cant stop climbing the mountain
We're sick and tired of keeping silence
We are we are we are

We are gonna
Come together
Come together now
We're gonna run together
We're gonna turn it upside down
Cuz with this smoke in the mirror I cant see your face
So lets fun to the fire escape
And we'll come together
and we'll come together now

Who are they , with their so called innovations
they hold on like they've found their own salvation
they shy away from the slightest alteration
But at the same time they got the same fascinations

We've got hopes on the horizon
And we cant stop climbing the mountain
We're sick and tired of keeping silence
We are we are we are

We are gonna
Come together
Come together now
We're gonna run together
We're gonna turn it upside down
Cuz with this smoke in the mirror I cant see your face
So lets fun to the fire escape
And we'll come together
and we'll come together now

just let go
it's a free fall
we're almost home
it's a free fall

We are gonna
Come together
Come together now
We're gonna run together
We're gonna turn it upside down
Cuz with this smoke in the mirror I cant see your face
So lets fun to the fire escape
And we'll come together
and we'll come together now

Every spring, keen-eyed biologists carrying fishing poles search the rolling hills near Los Banos, about two hours south of San Francisco. But they’re not looking for fish. They’re catching rock-paper-scissors lizards.

The research team collects Western side-blotched lizards, which come in different shades of blue, orange and yellow.

Barry Sinervo, a professor of ecology and evolutionary biology at UC Santa Cruz, leads the team. Their intricate mating strategies reminded the the researchers of the rock-paper-scissors game where rock beats scissors, scissors beats paper and paper beats rock.

It’s all about territories. Orange males tend to be the biggest and most aggressive. They hold large territories with several females each and are able to oust the somewhat smaller and less aggressive blues. Blue males typically hold smaller territories and more monogamous, each focusing his interest on a single female. Yellow males tend not to even form exclusive territories Instead they use stealth to find unaccompanied females with whom to mate.

The yellow males are particularly successful with females that live in territories held by their more aggressive orange competitors. Because the orange males spread their attention among several females, they aren’t able to guard each individual female against intruding yellow males. But the more monogamous blues males are more vigilant and chase sneaky yellow males away.

Their different strategies keep each other in check making the system stable. Sinervo believes this game has likely been in play for at least 15 million years.

--- How do side-blotched lizards choose a mate?

The males compete with each other, sometimes violently, for access to females. The females generally prefer males of their own color but also give preference to whichever color male is more rare that mating season.

--- Why do lizards do push up and down?
Male lizards do little pushups as a territorial display meant to tell competitors to back off. It’s best to use a warning instead of fighting right away because there’s always a danger of getting hurt in a fight. Some lizards like side-blotched lizards also use slow push ups to warn their neighbors of an incoming threat.

--- Why do side-blotched lizards fight?
Sometimes aggressive territorial displays are not enough to dissuade invaders so side-blotched lizards will resort to fighting. They have small sharp teeth and will lunge at each other inflicting bites and headbutts.

With the drought officially over and the summer heat upon us, people all across California are heading outdoors. For many, that means a day on the river or relaxing by the lake. The wet winter means there’s plenty of habitat for one of nature’s most curious creatures.

Water striders, also called pond skaters, seem to defy gravity. You’ve probably seen them flitting across the water’s surface, dodging ripples as they patrol streams and quiet backwater eddies.

Scientists like David Hu at Georgia Institute of Technology study how water striders move and how they make their living as predators lurking on the water’s surface. It’s an amazing combination of biology and physics best understood by looking up close. Very close.

--- What are water striders?
The common water strider (Gerris lacustris) is an insect typically found in slowly moving freshwater streams and ponds. They are able to move on the water's surface without sinking. They are easy to spot because they create circular waves on the surface of the water.

--- How do water striders walk on water?
Water tends to stick to itself (cohesion), especially at the surface where it meets the air (surface tension). Water striders don’t weigh very much and they spread their weight out with their long legs. Striders are also covered in microscopic hairs called micro-setae that repel water. Instead of sinking into the water, their legs push down and create dimples.

--- What do water striders eat?
Water striders are predators and scavengers. They use their ability to walk on water to their advantage, primarily eating other insects that fall into the water at get trapped by the surface tension. A water strider uses its tube-shaped proboscis to penetrate their prey’s exoskeleton, inject digestive enzymes and suck out the prey’s pre-digested innards.

At night, these parasites crawl onto your bed, bite you and suck your blood. Then they find a nearby hideout where they leave disgusting telltale signs. But these pests have an Achilles’ heel that stops them cold.

Adult bed bugs are about the size and color of an apple seed. After biting, they hide in a nearby cranny, like the seam of the mattress.

At the University of California, Irvine, biologist and engineer Catherine Loudon is working to create synthetic surfaces that could trap bed bugs. She was inspired by the tiny hooked hairs that grow from the leaves of some varieties of beans, such as kidney and green beans. In nature, these hairs, called trichomes, pierce through the feet of the aphids and leafhoppers that like to feed on the plants.

Researchers have found that these pointy hairs are just as effective against bed bugs, even though the bloodsucking parasites don’t feed on leaves. Loudon’s goal is to mimic a bean leaf’s mechanism to create an inexpensive, portable bed bug trap.

“You could imagine a strip that would act as a barrier that could be placed virtually anywhere: across the portal to a room, behind the headboard, on subway seats, an airplane,” Loudon said. “They have six legs, so that’s six opportunities to get trapped.”

--- Where do bed bugs come from?
Bed bugs don’t fly or jump or come in from the garden. They crawl very quickly and hide in travelers’ luggage. They also move around on secondhand furniture, or from apartment to apartment.

--- How can I avoid bringing bed bugs home?
“It would probably be a prudent thing to do a quick bed check if you’re sleeping in a strange bed,” said Potter. His recommendation goes for hotel rooms, as well as dorms and summer camp bunk beds. He suggests pulling back the sheet at the head of the bed and checking the seams on the top and bottom of the mattress and the box spring.
