Lyrics:

When I was boy
There's a dream that I had
That a war if was fought
Was for good against bad
And I woke up to find
That the world had gone mad

And we'd all fall down

And I feel like a child again
Sitting or turning
You're toying with power
Your fingers are burning
You're pushing so hard
That the worlds won't be turning

We'll all fall down

When you try to pretend
That you're a god upon high
With your party ideals
And your squeaky clean lies
When it comes to the crunch
You're no smarter than I

And we'll all fall down

If it's colour of creed or all time religion
Well fighting for that shows
A pure lack of vision
The fight that we strive
Is a fight to survive

And we'll all fall down

Well look in the mirror
And what do you see
An American, Russian
A soldier or me
When you all press the buttons
Just where will you be?

When we all fall down

Lyrics:

We were so young, we were too vain.
Dance in the dark, sing in the rain.
Time on our hands, hope in our hearts.

We were talking, passing strangers.
Moments caught across an empty room.
Wasted whispers, faded secrets.
Quickly passes, time goes, time goes by too soon.

We stood alone, silent and proud.
Moments unknown, lost in a crowd.
Running through memories like thieves in the night.
Clutching emotions, holding too tight.
Hold turns to dust, shattered by light.

We were talking, passing strangers.
Moments caught across an empty room.
Wasted whispers, faded secrets.
Quickly passes, time goes, time goes by too soon

We were talking, passing strangers.
Moments caught across an empty room.
Wasted whispers, faded secrets.
Quickly passes, time goes, time goes by too soon

We were talking, passing strangers.
Moments caught across an empty room.
Wasted whispers, faded secrets.
Quickly passes, time goes, time goes by too soon

Lyric:

The lights went out (The last fuse blew).
The clocks all stopped (It can't be true).
The program's wrong (What can we do?).
The printout's blocked (It relied on you).

The turbine cracked up.
The buildings froze up.
The system choked up.
What can we do?

Please remember to mention me,
In tapes you leave behind.

We stood still.
We all stood still.
Still stood still.
We're standing still.

The screen shut down (There's no reply).
The lifts all fall (A siren cries).
And the radar fades (A pilot sighs).
As the countdowns stall (The readout lies).

The turbines cracked up.
The buildings froze up.
The system choked up.
What can we do?

Please remember to mention me,
In tapes you leave behind.

We stood still.
We all stood still.
Still stood still.
We're standing still.

The black box failed (The codes got crossed).
And the jails decayed (The keys got lost).
Everyone kissed (We breathe exhaust).
In the new arcade (Of the holocaust).

The turbine cracked up.
The buildings froze up.
The system choked up.
What can we do?

Plese remember to mention me,
In tapes you might leave behind.

We stood still.
We all stood still.
Still stood still.
We're standing still

Lyric:

The sound is on the visions move
The image dance starts once again
They shuffle with a bovine grace and glide in syncopation
Just living lines from books we've read
With atmospheres of days gone by
With paper smiles
The screenplay calls a message for the nation

And those who sneer will fade and die
And those who laugh will surely fall
And those who know will always feel their backs against the thin wall
The thin wall
Thin wall

Grey men who speak of victory
Shed light upon their stolen life
They drive by night and act as if they're moved by unheard music
To step in time and play the part
With velvet voices smooth and cold
Their power games a game no more
And long the chance to use it

And those who dance will spin and turn
And those who wait will wait no more
And those talk will hear the word
And those who sneer will fade and die
And those who laugh will surely fall
And those who know will always feel their backs against the thin wall
The thin wall
Thin wall

The thin wall
The thin wall
The thin wall

And those who dance
The thin wall
And those who talk
The thin wall
And those who sneer
The thin wall
And those who laugh
The thin wall
And those who know
The thin wall
And those who dance
The thin wall
And those who wait
The thin wall
And those who talk

Something is growing inside that fruit fly in your kitchen. At dusk, the fly points its wings straight up and dies in a gruesome pose so that a fungus can ooze out and fire hundreds of reproductive spores.

Some of the scariest monsters are the ones that grow inside another being and take over its body. Think of the movie Alien, where the reptile-like space creature explodes out of its victim’s chest.

That monster might be fictional, but scientists are studying a fungus that’s horrifyingly real — at least for the flies it invades, turns into a zombie-like state and kills in order to reproduce.

“Oh, it’s a nightmare for the flies,” said entomologist Brad Mullens, who studied the fungus at the University of California, Riverside.

The fungus is known by its scientific name, Entomophthora muscae, which means “fly destroyer.” It lives off houseflies and fruit flies, among others.

“It’s a crazy system,” said Carolyn Elya, a biologist at Harvard. “The fungus only kills at dusk.”

Like a killer puppeteer, the fungus follows a precise clock.

At dusk on the fourth or fifth day after it picks up a fungal spore, an infected fruit fly stops flying. It starts behaving erratically, for example climbing up and down toothpicks that Elya puts into the vials where she keeps the infected insects.

Then the fly climbs to the top of the toothpick, a behavior Elya and other scientists refer to as “summiting.”

In an unusual twist, the fly then extends its mouthpart down, and some liquid drips out and glues the fly to the surface it’s standing on. Over the next 10 minutes, the fly’s wings ascend until they’re pointing upwards and it dies frozen in this lifelike pose.

Soon after, white spongy fungus oozes out of its abdomen. This white goo is made up of hundreds of lollipop-shaped protrusions which each launch a microscopic bell-shaped spore at high speed. Now the spores just need to get into another fly to grow.

--- Could this or a similar fungus “zombify” humans?
“No, it's very unlikely,” Elya said. “We can control our bodily temperature to kill invaders.”

-- Can we use the fungus as biological control?
Researchers have tried, but the spores are too fragile to grow in the lab.

Seen up close, the anatomy of a mosquito bite is terrifying. The most dangerous animal in the world uses six needle-like mouthparts to saw into our skin, tap a blood vessel and sometimes leave a dangerous parting gift.

DEEP LOOK is a ultra-HD (4K) short video series created by KQED San Francisco and presented by PBS Digital Studios. Explore big scientific mysteries by going incredibly small.

Scientists have discovered that the mosquito’s mouth, called a proboscis isn’t just one tiny spear. It’s a sophisticated system of thin needles, each of which pierces the skin, finds blood vessels and makes it easy for mosquitoes to suck blood out of them.

Male mosquitoes don’t bite us, but when a female mosquito pierces the skin, a flexible lip-like sheath called the labium scrolls up and stays outside as she pushes in six needle-like parts that scientists refer to as stylets.

Two of these needles, called maxillae, have tiny teeth. The mosquito uses them to saw through the skin. They’re so sharp you can barely feel the mosquito biting you.

“They’re like drill bits,” said University of California, Davis, biochemist Walter Leal.

Another set of needles, the mandibles, hold tissues apart while the mosquito works.

Then the sharp-tipped labrum needle probes under the skin, piercing a vessel and sucking blood from it.

The sixth needle – called the hypopharynx – drools saliva into us, and delivers chemicals that keep our blood flowing. Mosquito saliva also makes our blood vessels dilate, blocks our immune response and lubricates the proboscis. It causes us to develop itchy welts, and serves as a conduit for dangerous viruses and parasites.

---+ What is the deadliest animal in the world?
Mosquitoes are the deadliest animals in the world to us humans. The diseases they transmit kill hundreds of thousands of people each year.

---+ How many people get malaria each year?
In 2015, malaria, the deadliest mosquito-borne disease, killed roughly 635,000 people, mostly children under the age of five and pregnant women in sub-Saharan Africa.

---+ What diseases do mosquitoes transmit?
Malaria, dengue, yellow fever, West Nile and Zika are some of the diseases that mosquitoes transmit.

Dengue fever, transmitted Aedes aegypti mosquitoes, is estimated to make almost 400 million people sick with jabbing joint pain each year.

Scientists also believe that Aedes aegypti mosquitoes are the main culprit for more than 350 confirmed cases of congenital malformations associated with the Zika virus in the northeastern Brazilian state of Pernambuco. Since last October, an unusually high number of babies have been born there with small heads and a host of health problems like convulsions, suspected of being caused by a Zika virus infection early in their mother’s pregnancy.

---+ What diseases can I get from mosquitoes in the United States?
West Nile virus is the most important of several mosquito-transmitted viruses now native to the U.S., according to the Centers for Disease Control.

Planarians are tiny googly-eyed flatworms with an uncanny ability: They can regrow their entire bodies, even a new head. So how do they do it?

Nelson Hall wants you to know that the googly-eyed flatworm he just sliced into four pieces is going to be OK.

Three of the flatworm’s four pieces have started to wriggle away from each other and its head is moving in circles under Hall’s microscope. “The head will just go off and do its own thing,” said Hall, a doctoral student of bioengineering at Stanford University.

But in three weeks, the head, as well as the other pieces, will each have grown into a complete flatworm just like the one Hall sliced up, dark brown and about a half-inch long.

Hall and researchers around the world are hard at work trying to understand how these flatworms, called planarians, use powerful stem cells to regenerate their entire bodies, an ability humans can only dream of.

Animals like starfish, salamanders and crabs can regrow a tail or a leg. Planarians, on the other hand, can regrow their entire bodies – even their heads, which only a few animals can do.

---What is the difference between healing and regeneration?
When we suffer a severe injury, the best we can hope for is that our wounds will heal. “Healing is more like closing the wound and cleaning debris. It’s too short of a process to have tissue replacement,” said Hall. “Regeneration is replacing the tissue that was lost.”

---What are pluripotent stem cells?
If planarians can regrow body parts, why can’t we? Key to planarians’ regenerative ability are powerful cells called pluripotent stem cells, which make up one-fifth of their bodies and can grow into every new body part. Humans only have pluripotent stem cells during the embryonic stage, before birth. After that, we mostly lose our ability to sprout new organs.

“We have a couple of tissues that can regenerate, like the liver, the outer layers of the skin and the inner layers of the intestine, and the bone marrow,” said Dr. Stephen Badylak, Deputy Director of the McGowan Institute for Regenerative Medicine at the University of Pittsburgh. “But the way we heal most tissues is by forming scar tissue.”

Scientists hope that studying planarians could lead to treatments for humans in which our stem cells could be coaxed one day to regrow severed limbs or sick organs.

---How to grow a fingertip.
Doctors are limited in what they can currently do to help people who lose a limb or part of one. Badylak, who doesn’t study planarians, has developed a treatment at the University of Pittsburgh that helps patients regrow their fingertips after an accident.

He applies a powder made of animal collagen and substances that stimulate cells to grow, to help form a scaffold that attracts stem cells from the parts of the nail that weren’t cut off. The stem cells regrow the fingertip, which isn’t identical to the one that was cut off, but is functional.

It's not vanity. For cats, staying clean is a matter of life and death. And their tongue, specially equipped for the job, is just one of the things that makes cats such successful predators.

Even after thousands of years sharing our homes, cats still remain mysterious. For one thing, they spend an inordinate amount of time grooming themselves, up to half of their waking hours.

But all of that primping isn’t about vanity. For ambush predators like cats, staying clean is a matter of life and death.

In this episode of Deep Look we get up close and personal with these fastidious felines. By looking closely at cat tongues, research at MIT and Georgia Tech reveals clues to cats’ predatory prowess and finds inspiration for new technologies.

--- Why do cat’s tongues feel like sandpaper?
Cats’ tongues are covered in little spines called “papillae” that look like tiny hooks. Cats use their tongues to groom and the spines do a great job of detangling knots.

--- Why do cats spend so much time grooming?
Cat’s spend much of their day cleaning themselves- up to half of their waking hours! Cats are ambush predators and they need to stay clean in order to remain hidden from their prey. Prey species tend to be on the lookout for danger, and one whiff of the wrong odor can give the cat away.

--- Why do cats drink with their tongues?
Like most other mammals that are predators, cats have wide mouths to help them sink their teeth deep into their prey. The large opening on the sides of their mouth helps them get a better bite, but it makes it hard for them to create suction in order to drink. Instead they use their tongue to draw water up from the surface into a column. They then bite the column to get the water. They usually lap about four times per second.

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.

Pristine white sand dollars have long been the souvenir to commemorate a successful day at the beach. But most people who pick them up don’t realize that they’ve collected the skeleton of an animal, washed up at the end of a long life.

As it turns out, scientists say there’s a lot to be said about a sand dollar’s life. That skeleton -- also known as a test -- is really a tool, a remarkable feat of engineering that allows sand dollars to thrive on the shifting bottom of the sandy seafloor, an environment that most other sea creatures find inhospitable.

“They've done something really amazing and different,” said Rich Mooi, a researcher with the California Academy of Sciences in San Francisco. “They’re a pile of novelties, and they’ve gone way off the deep end in modifying their bodies to adapt to where they live.”

Mooi studies echinoderms, a word that roughly translates to “hedgehog skin.” It’s an aptly-fitting name for a group that includes sea urchins, sand dollars, sea stars and sea cucumbers. But Mooi says sand dollars really have his heart, in part because of their incredible adaptations.

--- What are sand dollars?
Sand dollars belong to a group of animals called Echinoderms that includes some more familiar animals like starfish and sea urchins. Sand dollars are actually a type of flattened sea urchin with miniaturized spines and tube feet more suited to sandy seafloors.

--- What do sand dollars eat?
Sand dollars consume sand but they get actual nutrition from the layer of algae and bacteria that coat the grains, not the sand itself.

--- Are sand dollars alive? Why do they Turn White?
When sand dollars are alive, they are covered in tiny tube feet and spines that make them appear like fuzzy discs. When they die, they lose their spines and tube feet exposing their white skeleton that scientists call a test. That skeleton is typically what people find on the beach.

Ominous creatures that lurk deep underground in the desert, like the sandworms in the classic science fiction novel "Dune," aren’t just make-believe. For ants and other prey, wormlions are a terrifying reality.

While quite small—they can grow up to an inch—wormlions are fly larvae that curl up their bodies like slingshots. Usually found under rock or log overhangs in dry, sandy landscapes, they’ll energetically fling soil, sand and pebbles out of the way to dig pit traps.

Once an unlucky critter falls in, wormlions move at lightning speed and quickly wrap their bodies around their victims. Squeezing them like boa constrictors, they also inject them with a paralyzing venom. They feed this way for several years, until they transform into adults.

Joyce Gross, a computer programmer for the UC Berkeley Natural History Museums, is fascinated by their unique hunting behavior.

“They have such a weird life history," she said. "They're the only flies that dig pits like this, and wait for prey to fall in, just like antlions.”

--- Are antlions and wormlions related?

While they use a similar hunting technique with pitfall traps, they’re actually two separate species.

--- How are antlions and wormlions different from each other?

Antlions have big jaws, while wormlions have tiny mouthparts typical of other flies. They also dig pits differently. Antlions (genus Myrmeleon) create deeper pits by digging backwards in a spiral-shaped path.

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.

It's stealth, not speed that makes owls such exceptional hunters. Zoom way in on their phenomenal feathers to see what makes them whisper-quiet.

Get a new perspective on our place in the universe and meet extraordinary new friends. Explore big scientific mysteries by going incredibly small.

--- How do owls hunt silently?

When birds flap their wings it creates turbulences in the air as it rushes over their wings. In general, the larger a bird is and the faster it flies, the larger the turbulence created and that means more sound.

The feathers at the leading edge of an owl’s wings have an unusual serrated appearance, referred to as a comb or fringe. The tiny hooked projections stick out and break up the wind as it flows over the owl’s wings reducing the size and sound of the turbulences.

Owl feathers go one step further to control sound. When viewed up-close, owl feathers appear velvety. The furry texture absorbs and dampens sound like a sound blanket. It also allows the feathers to quietly slide past each other in flight, reducing rusting sounds.

--- Why do owls hunt at night?

Owls belong to a group called raptors which also so includes with hawks, eagles and falcons. Most of these birds of prey hunt during the day and rely on. But unlike most other raptors, the roughly 200 species of owl are generally nocturnal while others are crepuscular, meaning that they’re active around dawn and dusk.

They have extremely powerful low-light vision, and finely tuned hearing which allows them to locate the source of even the smallest sound. Owls simply hide and wait for their prey to betray its own location. As ambush hunters, owls tend to rely on surprise more often than their ability to give chase.

--- Why do owls hoot?

With Halloween around the corner, you might have noticed a familiar sound in the night. It’s mating season for owls and the sound of their hooting fills the darkness.

According to Chris Clark, an an assistant professor of biology at UC Riverside,, “The reason why owls are getting ready to breed right now in the late fall is because they breed earlier than most birds. The bigger the bird the longer it takes for them to incubate their eggs and for the nestlings to hatch out and or the fledglings to leave the nest. Owls try to breed really early because they want their babies to be leaving the nest and practicing hunting right when there are lots of baby animals around like baby rabbits that are easy prey.”
