Lyrics:

Sleepwalk)
(Sleepwalk)
(Sleepwalk)

Rolling and falling, I'm choking and calling
Name after name after name

(Sleepwalk)
(Sleepwalk)
(Sleepwalk)

Naked and bleeding, the streetlights stray by me
Hurting my eyes with their glare

(Sleepwalk)
(Sleepwalk)
(Sleepwalk)

Helplessly breaking, exchanging my faces
Destined, we had to collide

(Sleepwalk)

Caught on the outside, I'm crumpling and crawling
Watching the day drag away
Spiralling deeper, I can't feel my fingers
Grip 'round my throat as I dream (dream, dream, dream dream)

(Sleepwalk)
(Sleepwalk)
(Sleepwalk)
(Sleepwalk)
(Sleepwalk)

Lyrics:

Standing on my own
It didn't mean that much to me
I thought I had it all
I didn't see the mystery
I stood the test of time
I took the step to find
Love's great adventure

I spoke a million words
They didn't mean that much to me
They rang around my head
Like empty tuneless harmonies
Love's great adventure mine

Lying side by side
It didn't mean that much to me
I started to enjoy
The poetry and symphonies
I took it in my stride
I hailed the Day i tried
Love's great adventure

A fool who couldn't see
It didn't mean that much to me
I couldn't understand
That's how the game is meant to be
Love's great adventure mine

Standing on my own
It didn't mean that much to me
I thought I had it all
I didn't see the mystery
I stood the test of time
I took the step to find
Love's great adventure

Lyrics:

We came to dance
Making moves from a passion play

The ties that bind us just slip away.
We came to dance
The piper calls out a different rhyme

He cracks the whip and we step in time.
Standing as the parade goes passing by
I hear a voice around my cry.
Like the sound of a distant drums
Rejected and alone.

A heart without a home
Then someone said:
We came to dance
Making moves from a passion play...

We came to dance.
Waiting as the panic grips my hand
Hearing prose from high command

Like a million times before
No dignity or grace

It's the price and not the race
And someone said:
We came to dance
Making moves from a passion play...

We came to dance.
We came to dance
Making moves from a passion play

The ties that bind us just slip away.

Take what you can
They said take it while you may.
But keep in mind penalty fits the crime

And it deals no softened blow.
We came to dance
Making moves from a passion play...

We came to dance
Making moves from a passion play...

We came to dance
Making moves from a passion play...

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.

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.

The killer punch of the mantis shrimp is the fastest strike in the animal kingdom, a skill that goes hand in hand with its extraordinary eyesight. They can see an invisible level of reality using polarized light, which could lead to a breakthrough in detecting cancer.

Aggressive, reef-dwelling mantis shrimp take more than one first-place ribbon in the animal kingdom. Outwardly resembling their lobster cousins, their colorful shells contain an impressive set of superpowers.

There are two types of mantis shrimp, named for their attack mode while hunting prey: smashers and spearers. With their spring-loaded, weaponized legs, these predators can crack a snail shell or harpoon a passing fish in a single punch.

The speed of these attacks has earned the mantis shrimp one of their world records: fastest strike in the animal kingdom.

Scientists are finding that another of their special abilities -- incredible eyesight -- has potential life-saving implications for people with cancer.

Mantis shrimp can perceive the most elusive attribute of light from the human standpoint: polarization. Polarization refers to the angle that light travels through space. Though it’s invisible to the human eye, many animals see this quality of light, especially underwater.

But mantis shrimp can see a special kind of polarization, called circular polarization. Scientists have found that some mantis shrimp species use circular polarization to communicate with each other on a kind of secret visual channel for mating and territorial purposes.

Inspired by the mantis shrimp’s superlative eyesight, a group of researchers is collaborating to build polarization cameras that would constitute a giant leap for early cancer detection. These cameras see otherwise invisible cancerous tissues by detecting their polarization signature, which is different between diseased and healthy tissues.

--- How fast is the mantis shrimp punch?

Their strike is about as fast as a .22 caliber rifle bullet. It’s been measured at 50mph.

--- What do mantis shrimp eat?

The “smasher” mantis shrimp eat hard-shelled creatures like snails and crabs. The “spearers” grab fish, worms, seahorses, and other soft-bodied prey by impaling them.

--- Where do mantis shrimp live?

In reefs, from the east coast of Africa to the west coast of Australia, and throughout Indonesia. A few species are scattered around the globe, including two in California.

A baby hairworm hitches a ride inside a cricket, feasting on its fat until the coiled-up parasite is ready to burst out. Then it hijacks the cricket's mind and compels it to head to water for a gruesome little swim.

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 8.

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 spectacle – the hairworm wriggling out of a cricket’s body, pushing its way out like the baby monster in the movie “Alien.”

How a hairworm ends up in a puddle, or another water source such as a stream, hot tub or a pet’s water dish, is a complex story. A young hairworm finds its way into a cricket or similar insect like a beetle or grasshopper, and once it’s grown into an adult, the parasite takes over its host’s brain to hitch a ride to the water.

As a result of the infection, crickets stop growing and reproducing. Male crickets infected by hairworms even lose their chirp, said Ben Hanelt, a biologist at the University of New Mexico who studies hairworms.

--- What *is* a hair worm?
A hair worm or hairworm – pick your spelling – is a nematomorph. Nematomorpha are a group of parasites. They’re long, thin worms that can grow to be several meters long inside their host.

--- Can humans be infected by hair worms?
There are reports of humans and cats and dogs being infected by hair worms, but hair worms aren’t after us or our pets because they can’t grow inside us, said Hanelt. They can only grow inside a host like a cricket or a related insect.

“What happens is that a dog, a cat, a human will ingest an adult (hair worm) somehow,” said Hanelt. “Could a cricket crawl in your sandwich before you take a bite? I don’t know. None of the studies that are out there talk about that. What they have been reported to do is to cause in many people intestinal distress.”

--- How do hair worms control crickets’ minds?
Scientists don’t understand the precise mechanism yet, but they believe that hairworms either boost chemicals in the crickets’ brains or pump chemicals into their brains.

Argentine ants are spreading across the globe, eliminating local ants with their take-no-prisoners tactics: invade, dismember, repeat. But this ruthless killer seems to have met its match in the winter ant, a California native with a formidable secret weapon.

--- About Argentine Ants and Winter Ants

For about 200 years, the Argentine ant expansion story has been the slow-moving train wreck of myrmecology, the study of ants.

Wherever they go, Argentine ants eliminate the competition with a take-no-prisoners approach. Invade, attack, dismember, consume. Repeat. The basic wisdom among ant scientists is that if you see Argentines, it’s already too late.

As early as the 1970s, scientists began to notice a peculiar fact about the Argentine ant. Usually, when ants from different colonies are put together, even from the same species, they fight. But Argentine worker ants can be combined from colonies in Spain, Japan and California, and they will recognize each other — they won’t fight.

Without this natural check, researchers say, a single colony of ants from Argentina has spread across continents and oceans.

But Jasper Ridge near Stanford is different. In 1993, ant biologist Deborah Gordon’s laboratory began tracking ant populations there. Jasper Ridge was unconquered territory for the Argentines, but they already had been spotted.

The Ph.D students conducting field research began to notice one species of native ant was holding its own inside the boundary of the Argentine advance. What, the Stanford researchers wondered, was different here?

In 2008, students in Gordon’s invasion ecology class studying the ants claimed to have made a novel discovery. The students watched the winter ants wave their abdomens at their enemies, known as “gaster-flagging” in ant circles, before a cloudy liquid blob appeared at the tip.

Approaching the secretion sent the Argentines reeling away. Touching it could kill them. Over the next two years, the students repeated and studied the winter ant’s apparently novel defensive behavior. They also analyzed the secretion. (Turns out it comes from the same gland used by the ants’ ancestors, wasps, to sting.)

They confirmed that in fact, with this amazing defense, the preserve’s winter ants were not only surviving, they’re now pushing back, opening up space for other native ant populations to rebound.

--- Do Argentine ants bite?

Not people. Too small to hurt a human, they’re far more dangerous to their competitors, from other ants about their size to some small birds(!).

--- How do you kill Argentine ants?

Pest control companies usually recommend slow-acting, fat or protein-based bait that allows the workers to carry the poison back to the nest.

--- Why are winter ants called that?

In areas where temperatures dip below freezing, winter ants remain active while most ant species hibernate.

“What nerve!” you might say. What… gall! And you’d be right. The wasps are called gall-inducers.

---+ What do oak galls look like?

If you’ve ever spent a Summer or Fall around oak trees – such as the stalwart Valley Oak – Quercus lobata, or the stately Blue Oak, Quercus douglasii – you may be familiar with the large, vaguely fruity-looking objects clinging to the branches and leaves. Commonly called oak apples, these growths are the last thing you’d want to put in your mouth. They are intensely bitter, loaded with tannin compounds – the same compounds that in modest amounts give red wine its pleasant dryness, and tea its refreshing earthy tang.

That said, the oak apple’s powerful astringency has been prized for millennia. Tanning leather, making ink or dye, and cleaning wounds have been but a few of the gall’s historical uses.

But on closer inspection of these oaks – and many other plants and trees such as willows, alders, manzanitas, or pines – you can find a rogue’s gallery of smaller galls. Carefully peeking under leaves, along the stems and branches, or around the flower buds and acorns will likely lead you to unexpected finds. Smooth ones. Spiky ones. Long skinny ones, flat ones, lumpy, boxy ones. From the size of a golf ball down to that of a poppy seed. These structures wear shades of yellow, green, brown, purple, pink and red – and sometimes all of the above. A single tree may be host to dozens of types of gall, each one caused by a specific organism. And their shapes range from the sublime to the downright creepy. One tree may be encrusted with them, like a Christmas tree laden with ornaments and tinsel; and the next tree over may be almost completely free of galls. Why? It’s a mystery.

---+ How do oak galls form?

Galls are generally formed when an insect, or its larvae, introduce chemicals into a specific location, to push the plant’s growth hormones into overdrive. This can result in a great profusion of normal cells, increased size of existing cells, or the alteration of entire plant structures into new, alien forms.

Lots of creatures cause them; midges, mites, aphids, flies, even bacteria and viruses. But the undisputed champs are a big family of little wasps called Cynipids– rarely exceeding the size of a mosquito, a quarter of an inch in length.

“These tiny wasps cannot sting,” says Dr. Kathy Schick, Assistant Specialist/Curatorial Assistant at the Essig Museum of Entomology at UC Berkeley. “Gall-inducers are fascinating in that they are very specialized to their organ of the host plant.”

---+ What are oak galls?

These wasp houses are not homes exactly, but more akin to nurseries. The galls serve as an ideal environment for wasp larvae, whether it is a single offspring, or dozens. The tree is tricked into generating outsize amounts of soft, pillowy tissue inside each gall, on which the larvae gladly gorge themselves as they grow.

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.

Cone Snails have an arsenal of tools and weapons under their pretty shells. These reef-dwelling hunters nab their prey in microseconds, then slowly eat them alive.

New research shows that cone snails — ocean-dwelling mollusks known for their brightly colored shells — attack their prey faster than almost any member of the animal kingdom.

There are hundreds of species of these normally slow-moving hunters found in oceans across the world. They take down fish, worms and other snails using a hollow, harpoon-like tooth that acts like a spear and a hypodermic needle. When they impale their prey, cone snails inject a chemical cocktail that subdues their meal and gives them time to dine at their leisure.

Cone snails launch their harpoons so quickly that scientists were previously unable to capture the movement on camera, making it impossible to calculate just how speedy these snails are. Now, using super-high-speed video, researchers have filmed the full flight of the harpoon for the first time.

From start to finish, the harpoon’s flight takes less than 200 micro-seconds. That’s one five-thousandth of a second. It launches with an acceleration equivalent to a bullet fired from a pistol.

So how do these sedentary snails pull off such a high-octane feat? Hydrostatic pressure — the pressure from fluid — builds within the half of the snail’s proboscis closest to its body, locked behind a tight o-ring of muscle. When it comes time to strike, the muscle relaxes, and the venom-laced fluid punches into the harpoon’s bulbous base. This pressure launches the harpoon out into the snail’s unsuspecting prey.

As fast as the harpoon launches, it comes to an even more abrupt stop. The base of the harpoon gets caught at the end of the proboscis so the snail can reel in its meal.

The high-speed action doesn’t stop with the harpoon. Cone snail venom acts fast, subduing fish in as little as a few seconds. The venom is filled with unique molecules, broadly referred to as conotoxins.

The composition of cone snail venom varies from species to species, and even between individuals of the same species, creating a library of potential new drugs that researchers are eager to mine. In combination, these chemicals work together to rapidly paralyze a cone snail’s prey. Individually, some molecules from cone snail venom can provide non-opioid pain relief, and could potentially treat Parkinson’s disease or cancer.

--- Where do cone snails live?

There are 500 species of cone snails living in the Indian and Pacific Oceans, the Caribbean and Red Seas, and the Florida coast.

--- Can cone snails kill humans?

Most of them do not. Only eight of those 500 species, including the geography cone, have been known to kill humans.

--- Why are scientists interested in cone snails?

Cone snail venom is derived from thousands of small molecules call peptides that the snail makes under its shell. These peptides produce different effects on cells, which scientists hope to manipulate in the treatment of various diseases.

Conceived in the open sea, tiny spaceship-shaped sea urchin larvae search the vast ocean to find a home. After this incredible odyssey, they undergo one of the most remarkable transformations in nature.

Every summer, millions of people head to the coast to soak up the sun and play in the waves. But they aren’t alone. Just beyond the crashing surf, hundreds of millions of tiny sea urchin larvae are also floating around, preparing for one of the most dramatic transformations in the animal kingdom.

Scientists along the Pacific coast are investigating how these microscopic ocean drifters, which look like tiny spaceships, find their way back home to the shoreline, where they attach themselves, grow into spiny creatures and live out a slow-moving life that often exceeds 100 years.“These sorts of studies are absolutely crucial if we want to not only maintain healthy fisheries but indeed a healthy ocean,” says Jason Hodin, a research scientist at the University of Washington’s Friday Harbor Laboratories.

Sea urchins reproduce by sending clouds of eggs and sperm into the water. Millions of larvae are formed, but only a handful make it back to the shoreline to grow into adults.


--- What are sea urchins?

Sea urchins are spiny invertebrate animals. Adult sea urchins are globe-shaped and show five-point radial symmetry. They move using a system of tube feet. Sea urchins belong to the phylum Echinodermata along with their relatives the sea stars (starfish), sand dollars and sea slugs.

--- What do sea urchins eat?

Sea urchins eat algae and can reduce kelp forests to barrens if their numbers grow too high. A sea urchin’s mouth, referred to as Aristotle’s lantern, is on the underside and has five sharp teeth. The urchin uses the tube feet to move the food to its mouth.

--- How do sea urchins reproduce?

Male sea urchins release clouds of sperm and females release huge numbers of eggs directly into the ocean water. The gametes meet and the sperm fertilize the eggs. The fertilized eggs grow into free-swimming embryos which themselves develop into larvae called plutei. The plutei swim through the ocean as plankton until they drop to the seafloor and metamorphosize into the globe-shaped adult urchins.
