Honey bees make honey from nectar to fuel their flight – and our sweet tooth. But they also need pollen for protein. So they trap, brush and pack it into baskets on their legs to make a special food called bee bread.

Spring means honey bees flitting from flower to flower. This frantic insect activity is essential to growing foods like almonds, raspberries and apples. Bees move pollen, making it possible for plants to grow the fruit and seeds they need to reproduce.

But honey bees don’t just move pollen from plant to plant. They also keep a lot for themselves. They carry it around in neat little balls, one on each of their hind legs. Collecting, packing and making pollen into something they can eat is a tough, intricate job that’s essential to the colony’s well-being.

Older female adult bees collect pollen and mix it with nectar or honey as they go along, then carry it back to the hive and deposit it in cells next to the developing baby bees, called larvae. This stored pollen, known as bee bread, is the colony’s main source of protein.

“You don’t have bees flying along snacking on pollen as they’re collecting it,” said Mark Carroll, an entomologist at the US Department of Agriculture’s Carl Hayden Bee Research Center in Tucson. “This is the form of pollen that bees are eating.”

--- What is bee bread?
It’s the pollen that worker honey bees have collected, mixed with a little nectar or honey and stored within cells in the hive.

--- What is bee bread used for?
Bee bread is the main source of protein for adult bees and larvae. Young adult bees eat bee bread to make a liquid food similar to mammal’s milk that they feed to growing larvae; they also feed little bits of bee bread to older larvae.

--- How do honey bees use their pollen basket?
When a bee lands on a flower, it nibbles and licks off the pollen, which sticks to its head. It wipes the pollen off its eyes and antennae with a brush on each of its front legs, using them in tandem like windshield wipers. It also cleans the pollen off its mouth part, and as it does this, it mixes it with some saliva and a little nectar or honey that it carries around in a kind of stomach called a crop.
Then the bee uses brushes on its front, middle and hind legs to move the pollen, conveyor-belt style, front to middle to back. As it flies from bloom to bloom, the bee combs the pollen very quickly and moves it into baskets on its hind legs. Each pollen basket, called a corbicula, is a concave section of the hind leg covered by longish hairs that bend over and around the pollen.

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.

California's historic drought is finally over thanks largely to a relentless parade of powerful storms that have brought the Sierra Nevada snowpack to the highest level in six years, and guaranteed skiing into June. All that snow spurs an age-old question -- is every snowflake really unique?

“It’s one of these questions that’s been around forever,” said Ken Libbrecht, a professor of physics at the California Institute of Technology in Pasadena. “I think we all learn it in elementary school, the old saying that no two snowflakes are alike.”

--- How do snowflakes form?
Snow crystals form when humid air is cooled to the point that molecules of water vapor start sticking to each other. In the clouds, crystals usually start forming around a tiny microscopic dust particle, but if the water vapor gets cooled quickly enough the crystals can form spontaneously out of water molecules alone. Over time, more water molecules stick to the crystal until it gets heavy enough to fall.

--- Why do snowflakes have six arms?
Each water molecule is each made out of one oxygen atom and two hydrogen atoms. As vapor, the water molecules bounce around slamming into each other. As the vapor cools, the hydrogen atom of one molecule forms a bond with the oxygen of another water molecule. This is called a hydrogen bond. These bonds make the water molecules stick together in the shape of a hexagonal ring. As the crystal grows, more molecules join fitting within that same repeating pattern called a crystal array. The crystal keeps the hexagonal symmetry as it grows.

--- Is every snowflake unique?
Snowflakes develop into different shapes depending on the humidity and temperature conditions they experience at different times during their growth. In nature, snowflakes don’t travel together. Instead, each takes it’s own path through the clouds experiencing different conditions at different times. Since each crystal takes a different path, they each turn out slightly differently. Growing snow crystals in laboratory is a whole other story.

Natural World: Ant Attack
In a quiet patch of forest, life is about to be turned upside down for its animal residents - the ants are coming. Spiders, scorpions and even forest crabs don't stand a chance. As food runs out, the ants, driven on by the ever-hungry grubs in the nest, have no choice but to attack the not so easily defeated termites. Armed with chemical weapons and fearsome jaws that could crush an ant to pulp, they're the ants' toughest adversaries. From the raw terror of battle to the inner-workings of an ant colony, this is television as you've never seen it before.

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.

--- 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.”

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.
