Lyrics:

Dancing with tears in my eyes
Weeping for the memory of a life gone by
Dancing with tears in my eyes
Living out a memory of a love that died

It's five and I'm driving home again
It's hard to believe that it's my last time
The man on the wireless cries again
It's over, it's over

Dancing with tears in my eyes
Weeping for the memory of a life gone by
Dancing with tears in my eyes
Living out a memory of a love that died

It's late and I'm with my love alone
We drink to forget the coming storm
We love to the sound of our favourite song
Over and over

Dancing with tears in my eyes
Living out a memory of a love that died

It's time and we're in each other's arms
It's time but I don't think we really care

Dancing with tears in my eyes
Weeping for the memory of a life gone by
Dancing with tears in my eyes
Weeping for the memory of a life gone by

Dancing with tears in my eyes

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

Ultravox -- Hymn :: Lyrics ::Give us this day all that you showed me.
The power and the glory 'til thy kingdom come.

Give us this day all that you showed me,
The power and the glory 'til thy kingdom come.
Give me all the story book told me,
The faith and the glory 'til thy kingdom comes.

And they said that in our time,
All that's good will fall from grace.
Even saints would turn their face,
In our time.

And they told us that in our days,
Different words said in different ways,
Have other meaning from he who says,
In our time.

And they said that in our time,
We would reap from their legacy,
We would learn from what they had seen,
In our time.

And they told us that in our days,
We would know what was high on high,
We would follow and not defy,
In our time.

Most firefly flashes are pure romance, a sexy form of skywriting. But one variety copies the mating signals of others to lure them to their demise.

Most of the blinking signals that fireflies send out are intended to attract mates. But researchers are finding out that in some cases, these romantic overtures are not all wine and roses.

Females of one firefly group, the genus Photuris, have learned to copy other fireflies’ flashes to attract the males of those species. When one arrives, she pounces, first sucking his blood, then devouring his insides.

These “femme fatale” fireflies live throughout the Eastern U.S alongside the fireflies they target. They can develop widely varying light shows to target whatever species are in the area.

The predatory habits of Photuris are just one example of how much individual firefly signals can differ from one another.

The male Common Eastern Firefly, for example, is known for his fish hook-shaped aerial maneuver, which he repeats at six-second intervals. That characteristic move has earned the species the nickname “Big Dipper.”

The male Big Dipper hopes this bit of skywriting will get him noticed by females hiding in the grass. If the female likes what she sees, her reply comes as a single pulse from her smaller, heart-shaped lantern. That’s his invitation to land and mate.

Most firefly interactions follow the same pattern, with roving males advertising themselves to concealed females. Within a species, the back-and-forth signals are so reliable that it’s easy to attract the male fireflies with even a simple decoy.

Firefly light is biochemical. But fireflies like the Big Dippers do much more with chemistry than just make light. They can mix together an array of other compounds, including invisible pheromones for mating, and others called lucibufagins (“loosa-BOOF-ajins”) that ward off predators like spiders and birds.

At some point, the Photuris “femme fatale” fireflies lost the ability to make their own lucibufagins. So instead of chemistry, these bigger, stronger fireflies became adept at imitation, and evolved to turn into insect vampires to take these valuable compounds from other fireflies to boost their own defenses.

And it works. In experiments, predators avoided Photuris fireflies that had recently preyed on other fireflies.

--- Where do fireflies live?

There are fireflies worldwide, but in the U.S., you’ll find them in the Midwest and Eastern U.S. There are a few species in the West, including the California Pink Glow-worm.

--- Why do fireflies flash?

Mostly, it’s to attract mates. One sex, usually the male, uses a more elaborate flash pattern to get the attention of the opposite sex. Then the female signals her interest with a simpler flash.

--- Why do fireflies glow after they die?

The chemicals in the firefly that make light, luciferin and luciferase, remain viable after it dies, and the reaction that creates the light thrives on oxygen, which is of course plentiful in the air.

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.

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.

http://staff.washington.edu/hodin/
http://depts.washington.edu/fhl/

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.

There's a chemical arms race going on in the Sonoran Desert between a highly venomous scorpion and a particularly ferocious mouse. The outcome of their battle may one day change the way doctors treat pain in people.

Commonly found in the Sonoran Desert, the Arizona bark scorpion (Centruroides sculpturatus) is the most dangerous scorpion in the continental United States. According to Keith Boesen, Director of the Arizona Poison & Drug Information Center, about 15,000 Americans report being stung by scorpions every year in the U.S. The worst stings, about 200 annually, are attributed to this one species. Its sting can cause sharp pain along with tingling, swelling, numbness, dizziness, shortness of breath, muscular convulsions, involuntary eye movements, coughing and vomiting. Children under two years old are especially vulnerable. Since 2000, three human deaths have been attributed to the Arizona bark scorpion in the United States, all within Arizona.

But there is one unlikely creature that appears unimpressed. While it may not look the part, the Southern grasshopper mouse (Onychomys torridus) is an extremely capable hunter. It fearlessly stalks and devours any beetles or grasshoppers that have the misfortune to cross its path. But this mouse has a particular taste for scorpions.

The scorpion venom contains neurotoxins that target sodium and potassium ion channels, proteins embedded within the surface of the nerve and muscle cells that play an important role in regulating the sensation of pain. Activating these channels sends signals down the nerves to the brain. That’s what causes the excruciating pain that human victims have described as the feeling like getting jabbed with a hot needle. Others compare the pain to an electric shock. But the grasshopper mouse has an entirely different reaction when stung.

Within the mouse, a special protein in one of the sodium ion channels binds to the scorpion’s neurotoxin. Once bound, the neurotoxin is unable to activate the sodium ion channel and send the pain signal. Instead it has the entirely opposite effect. It shuts down the channel, keeping it from sending any signals, which has a numbing effect for the mouse.


--- How many species of scorpion are there?

There are almost 2,000 scorpion species, but only 30 or 40 have strong enough poison to kill a person.

--- Are scorpions insects?

Scorpions are members of the class Arachnida and are closely related to spiders, mites, and ticks.

--- Where do Arizona bark scorpions live?

Commonly found in the Sonoran Desert, the Arizona bark scorpion (Centruroides sculpturatus) is the most dangerous scorpion in the continental United States. The Arizona bark scorpion’s preference for hanging to the underside of objects makes dangerous encounters with humans more likely.

The archerfish hunts by spitting water at terrestrial targets with weapon-like precision, and can even tell human faces apart. Is this fish smarter than it looks?

Humans always have assumed we’ve cornered the market on intelligence. But because of archerfish and other bright lights in the animal kingdom, that idea is itself evolving.

Archerfish normally make their living in the mangrove forests of Southeast Asia and Australia, where they spit water at ants, beetles and other insects living on the trees’ half-submerged roots. The fish’s high-pressure projectiles knock prey from their perches into the water, and the fish swoops in.

This novel feeding behavior, restricted to only seven species of fish, has attracted the attention of researchers ever since it was first described in 1764.

The jet’s tip and tail unite at the moment of impact, which is critical to the success of the attack, especially as the target distance approaches the limit of the fish’s maximum spitting range of about six feet. The fish accomplishes this feat of timing through deliberate control of its highly-evolved mouthparts, in particular its lips, which act like an adjustable hose that can expand and contract while releasing the water.

So in a way, to hit a target that’s further away, the fish doesn’t spit harder. It spits smarter. But just how smart is an archerfish?

Using the archerfish’s spitting habits as a starting point, one researcher trained some lab fish to spit at an image of one human face with food rewards. Then, on a monitor suspended over the fish tank, she showed them a series of other faces, in pairs, adding in the familiar one.

When the trained fish saw that familiar face, they would spit, to a high degree of accuracy. In a sense, the fish “recognized” the face, which should have been beyond the capacity of its primitive brain.

--- Where do archerfish live?

In Thailand, Australia, and other parts of Southeast Asia, usually in mangrove forests.

--- What do archerfish eat?

Insects and spiders that live close to the waterline. Archerfish won’t eat anything once it’s sinks too far below the surface.

--- How do archerfish spit?

They squeeze water through their mouth opening, using specially evolved mouthparts.

When predators attack, daddy longlegs deliberately release their limbs to escape. They can drop up to three and still get by just fine.

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

We all know it’s not nice to pull the legs off of bugs.

Daddy longlegs don’t wait for that to happen. These arachnids, related to spiders, drop them deliberately. A gentle pinch is enough to trigger an internal system that discharges the leg. Whether it hurts is up for debate, but most scientists think not, given the automatic nature of the defense mechanism.

It’s called autotomy, the voluntary release of a body part.

Two of their appendages have evolved into feelers, which leaves the other six legs for locomotion. Daddy longlegs share this trait with insects, and have what scientists call the “alternate tripod gate,” where three legs touch the ground at any given point.

That elegant stride is initially hard-hit by the loss of a leg. In the daddy longlegs’ case, the lost leg doesn’t grow back.

But they persevere: A daddy longlegs that is one, two, or even three legs short can recover a surprising degree of mobility by learning to walk differently. And given time, the daddy longlegs can regain much of its initial mobility on fewer legs.

Once these adaptations are better understood, they may have applications in the fields of robotics and prosthetic design.

--- Are daddy longlegs a type of spider?

No, though they are arachnids, as spiders are. Daddy longlegs are more closely related to scorpions.

--- How can I tell a daddy longlegs from a spider?

Daddy longlegs have one body segment (like a pea), while spiders have two (like a peanut). Also, you won’t find a daddy longlegs in a web, since they don’t make silk.

--- Can a daddy longlegs bite can kill you?

Daddy longlegs are not venomous. And despite what you’ve heard about their mouths being too small, they could bite you, but they prefer fruit.

Lyrics
Once, we did run
How we chased a million stars
and touched as only one can
Once, we did play
How the past delivered you
Amidst our youth we'd dream away, away

As if I knew the words I'm sure you'll hear
Of how we met as you recall so clear

Once, we did love
Long ago how did I forget
Holding you so closely

Look, how I move
Chance would have me glance at you
To know how you move me
Me, all barriers fall around us as we hear
Of memories known and matters long ago, so clear

Once, we did run
How we chased a million stars
and touched as only one can

Once, we did play
How the past delivered you
Amidst our youth we'd dream away, away
As if I knew the words I'm sure you'll hear
Of how we met as you recall so clear

Once, we did love
Long ago how did I forget
Holding you so closely

Look, how I move
Chance would have me glance at you
To know how you move me
Me, all barriers fall around us as we hear
Of memories known and matters long ago, so clear
