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.

The Peruvian Amazon is a dangerous place when you're small. So the young Inga tree hires ants as bodyguards to protect its vulnerable leaves. Their pay: delicious nectar served up in tiny ant-sized dishes. But will the ants keep up their end of the bargain?

For some, ants are welcome guests. In the Amazon rainforest of Peru, a type of tree called the Inga actively encourages ants to stick around.

The tree, which is related to plants that produce beans and other legumes, grows tiny structures near the base of its leaves, called nectaries, that secrete a sugary fluid to feed to the ants. In turn, the ants serve as bodyguards, protecting the Inga and its nectaries from invading herbivores.

“Plants have all kinds of defenses, but because Inga leaves are not as toxic as many other plants,” says Suzanne Koptur, a professor of biology at Florida International University, “they’re good food for herbivores of all sizes and shapes, from big mammals like sloths and monkeys to little invertebrates like caterpillars.“

The rainforest is especially dangerous for young trees. The branches and leaves of mature trees merge together high in the air forming a canopy. Young trees on the forest floor struggle to get enough light. Young trees also have fewer leaves, and losing even a few to herbivores can threaten their survival.

They may be small, but few species want to tangle with the aggressive and territorial big-headed ants.

"Ants have powers in numbers, especially if they bite and sting," says Koptur.

The ants keep most herbivores, especially hungry caterpillars, away from the young trees. Simply put, the trees provide nectar to the ants in exchange for protection.

--- What is mutualism?

In biology, mutualism refers to a relationship between two organisms that benefits both of parties. Mutualism is one type of symbiotic relationship.


--- What are caterpillars?

Caterpillars are the larvae of butterflies and caterpillars. Young caterpillars hatch out of eggs, eat, grow and molt. They eventually pupate inside their cocoons and then emerge as winged adults.

--- What is plant nectar?

Nectar is a sugary liquid secreted by plants through structures called nectaries. Nectaries are commonly found in flowers to attract pollinators. Some plants also have extra-floral nectaries located outside of the flowers. To attract animals including ants and predatory wasps that protect the plant from herbivores.

Rain falls and within seconds dried-up moss that's been virtually dead for decades unfurls in an explosion of green. The microscopic creatures living in the moss come out to feed. Scientists say the genes in these “resurrection plants” might one day protect crops from drought.

How does moss grow?

Mosses don’t have roots. Their porous cells absorb water like a sponge, whenever it’s available.

When there’s no rain, mosses dry out completely and stop photosynthesizing. That is, they stop using carbon dioxide and the light of the sun to grow. They’re virtually dead, reduced to a pile of chemicals, and can stay that way for years. Researchers have found dry, 100-year-old moss samples in a museum that came back to life when water was added.

Read an extended article on how scientists hope to use resurrection plants to create crops that can survive drought:

Why can't you just flick a tick? Because it attaches to you with a mouth covered in hooks, while it fattens up on your blood. For days. But don't worry – there *is* a way to pull it out.

Spring is here. Unfortunately for hikers and picnickers out enjoying the weather, the new season is prime time for ticks, which can transmit bacteria that cause Lyme disease.

How they latch on – and stay on – is a feat of engineering that scientists have been piecing together. Once you know how a tick’s mouth works, you understand why it’s impossible to simply flick a tick.

The key to their success is a menacing mouth covered in hooks that they use to get under the surface of our skin and attach themselves for several days while they fatten up on our blood.

“Ticks have a lovely, evolved mouth part for doing exactly what they need to do, which is extended feeding,” said Kerry Padgett, supervising public health biologist at the California Department of Public Health in Richmond. “They're not like a mosquito that can just put their mouth parts in and out nicely, like a hypodermic needle.”

Instead, a tick digs in using two sets of hooks. Each set looks like a hand with three hooked fingers. The hooks dig in and wriggle into the skin. Then these “hands” bend in unison to perform approximately half-a-dozen breaststrokes that pull skin out of the way so the tick can push in a long stubby part called the hypostome.

“It’s almost like swimming into the skin,” said Dania Richter, a biologist at the Technische Universität Braunschweig in Germany, who has studied the mechanism closely. “By bending the hooks it’s engaging the skin. It’s pulling the skin when it retracts.”

The bottom of their long hypostome is also covered in rows of hooks that give it the look of a chainsaw. Those hooks act like mini-harpoons, anchoring the tick to us for the long haul.

“They’re teeth that are backwards facing, similar to one of those gates you would drive over but you're not allowed to back up or else you'd puncture your tires,” said Padgett.

--- How to remove a tick.
Kerry Padgett, at the California Department of Public Health, recommends grabbing the tick close to the skin using a pair of fine tweezers and simply pulling straight up.

“No twisting or jerking,” she said. “Use a smooth motion pulling up.”

Padgett warned against using other strategies.

“Don't use Vaseline or try to burn the tick or use a cotton swab soaked in soft soap or any of these other techniques that might take a little longer or might not work at all,” she said. “You really want to remove the tick as soon as possible.”

--- What happens if the mouth of a tick breaks off in your skin?
Don’t worry if the tick’s mouth parts stay behind when you pull.

“The mouth parts are not going to transmit disease to people,” said Padgett.

If the mouth stayed behind in your skin, it will eventually work its way out, sort of like a splinter does, she said. Clean the bite area with soap and water and apply antibiotic ointment.

Rattlesnakes are ambush predators, relying on staying hidden to get close to their prey. They don’t sport the bright colors that some venomous snakes use as a warning to predators.

Fortunately, rattlesnakes have an unmistakable warning, a loud buzz made to startle any aggressor and hopefully avoid having to bite.

If you hear the rattlesnake’s rattle here’s what to do: First, stop moving! You want to figure out which direction the sound is coming from. Once you do, slowly back away.

If you do get bitten, immobilize the area and don't overly exert yourself. Immediately seek medical attention. You may need to be treated with antivenom.

DO NOT try to suck the venom out using your mouth or a suction device.

DO NOT try to capture the snake and stay clear of dead rattlesnakes, especially the head.

--- How do rattlesnakes make that buzzing sound?
The rattlesnake’s rattle is made up of loosely interlocking segments made of keratin, the same strong fibrous protein in your fingernails. Each segment is held in place by the one in front and behind it, but the individual segments can move a bit. When the snake shakes its tail, it sends undulating waves down the length of the rattle, and they click against each other. It happens so fast that all you hear is a buzz and all you see is a blur.

--- Why do rattlesnakes flick their tongue?
Like other snakes, rattlesnakes flick their tongues to gather odor particles suspended in liquid. The snake brings those scent molecules back to a special organ in the roof of their mouth called the vomeronasal organ or Jacobson's organ. The organ detects pheromones originating from prey and other snakes.

Most flowering plants are more than willing to spread their pollen around. But some flowers hold out for just the right partner. Bumblebees and other buzz pollinators know just how to handle these stubborn flowers. They vibrate the blooms, shaking them until they give up the nutritious pollen.

In the summertime, the air is thick with the low humming of bees delivering pollen from one flower to the next. If you listen closely, a louder buzz may catch your ear.

This sound is the key to a secret stash of pollen that some flowers hide deep within their anthers, the male parts of the plant. Only pollinators that buzz in just the right way can vibrate tiny grains out of minuscule holes at the top of the anthers for a protein-rich snack.

The strategy, called buzz-pollination, is risky. But it’s also critical to human agriculture. Tomatoes, potatoes and eggplants need wild populations of buzz pollinators, such as bumblebees, to produce fruit. Honeybees can’t do it.

Plants need a way to get the pollen — basically sperm — to the female parts of another flower. Most plants lure animal pollinators to spread these male gametes by producing sugary nectar. The bee laps up the sweet reward, is dusted with pollen and passively delivers it to the next bloom.

In contrast, buzz-pollinated flowers encourage bees to eat the pollen directly and hope some grains will make it to another flower. The evolutionary strategy is baffling to scientists.

“The flower is almost like playing hard to get,” says Anne Leonard, a biologist at the University of Nevada, Reno who studies buzz pollination. “It’s intriguing because these buzz-pollinated plants ask for a huge energy investment from the bees, but don’t give much back.”


--- What is buzz pollination?
Most flowering plants use sugary nectar as bait to attract bees and other pollinators, which get coated in pollen along the way. And since bees are messy, they inadvertently scatter some of that pollen onto the female part of the next flower they visit.

But some flowers lock their pollen up in their anthers, the male parts of the flower, instead of giving it away freely. The only way for the pollen to escape is through small holes called pores. Some pollinators like bumblebees (but not honeybees) are able to vibrate the flower’s anthers which shakes up the pollen and causes it to spew out of the pores.

The bumblebee collects the pollen and uses it as a reliable and protected source of protein.

--- What important crops use buzz pollination to make food?

The most important crops that use buzz pollination are potatoes, tomatoes, pumpkins, eggplants, cranberries and blueberries


--- What animals are capable of buzz pollination?
Many types of bees engage in buzz pollination, also called sonication. The most common is probably the bumblebee. Honeybees generally don’t use buzz pollination.

Some corals look like undersea gardens, gently blowing in the breeze. Others look like alien brains. But in their skeletons are clues that promise to give scientists a detailed picture of the weather from 500 years ago. Reading these bones? Easy. As long as you have the world's most powerful X-ray laser.

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.

Is coral a plant or animal?

Corals are unusual creatures. They are actually a partnership- or symbiosis- between an animal (a polyp) and a plant (algae) in which they work together to survive and thrive.

How does coral grow?

Tiny animals called polyps form an exoskeleton to live in. When one polyp dies, another builds a new home right on top of the old one. Beneath lies the abandoned exoskeletons, like an ancient city made of layer upon layer of old dwellings.

What is coral made of?

Coral exoskeletons are mostly made of calcium carbonate. But sometimes the polyps incorporate tiny amounts of other elements from the surrounding water, including the element strontium. Biologists don’t fully understand why polyps absorb strontium, but it’s a phenomenon that happens consistently across the world’s oceans.

When sea surface temperatures are warmer, corals absorb less strontium into their exoskeletons. When they are colder, they absorb more. By comparing the strontium-to-calcium ratio over time, scientists are able to reconstruct sea surface temperatures from the past. They also can chart long-term climate cycles that occurred over the lifespan of the coral. Since these corals can live for over 500 years, this gives us insights into the weather hundreds of years before written scientific records.

Dogs have a famously great sense of smell, but what makes their noses so much more powerful than ours? They're packing some sophisticated equipment inside that squishy schnozz.

--- How much more powerful is a dog’s sense of smell compared to a human?
According to one estimate, dogs are 10,000-100,000 times more sensitive to smell than humans. They have about 15 times more olfactory neurons that send signals about odors to the brain. The neurons in a dog’s nose are spread out over a much larger and more convoluted area allowing them more easily decipher specific chemicals in the air.

--- Why are dog noses wet?
Dog noses secrete mucus which traps odors in the air and on the ground. When a dog licks its nose, the tongue brings those odors into the mouth allowing it to sample those smells. Dogs mostly cool themselves by panting but the mucus on their noses and sweat from their paws cool through evaporation.

--- Why do dog nostrils have slits on the side?
Dogs sniff about five times per second. The slits on the sides allows exhaled air to vent towards the sides and back. That air moving towards the back of the dog creates a low air pressure region in front of it. Air from in front of the dog rushes in to fill that low pressure region. That allows the nose to actively bring odors in from in front and keeps the exhaled air from contaminating new samples.

Pour les justes les yeux du Seigneur, des cœurs brisés le Seigneur est proche.
The Lord watches over the upright; God is close to the broken-hearted.
Oči Gospodnje gledaju pravedne; blizu je Gospodin onima koji su skršena srca.
Gli occhi del Signore sui giusti; il Signore è vicino a chi ha il cuore ferito.
Los ojos del Señor miran al justo; El Señor está cerca del que sufre.
Oculi Domini super iustos; iuxta est Dominus iis, qui contrito sunt corde.
因為上主的雙目垂顧正義的人; 上主親近心靈破碎的人.

(Ps 34, 16a.19a)

Text:

Pour les justes les yeux du Seigneur, des cœurs brisés le Seigneur est proche.

Je bénirai le Seigneur en tout temps, sa louange sans cesse en ma bouche. Des cœurs.
Qui regarde vers Dieu resplendira et sur son visage point de honte. Des cœurs.
Le Seigneur rachète l'âme de ses serviteurs, qui s'abrite en lui n'expiera point. Des cœurs.
Gloire au Père, et au Fils, et au Saint-Esprit. Pour.

Mon Dieu, mon Dieu, pourquoi m'as-tu abandonné ?
Loin de me sauver, les paroles que je rugis !
Le jour j'appelle, point de réponse,
la nuit, point de silence pour moi.

Et toi pourtant, Dieu Saint,
qui habites les louanges d'Israël !
En toi nos Pères ont espéré,
espéré et tu les as délivrés ;
vers toi, quand ils criaient ils échappaient,
en toi ils espéraient, jamais en vain.

Et moi, ver, non point homme,
honte du genre humain, rebut du peuple,
tous ceux qui me voient me bafouent,
ils ricanent et hochent la tête :
"Il s'est remis au Seigneur qu'il le libère !
Qu'il le délivre puisqu'il est son ami !"

Lyrics:

Don't leave me in all this pain
Don't leave me out in the rain
Come back and bring back my smile
Come and take these tears away
I need your arms to hold me now
The nights are so unkind
Bring back those nights when I held you beside me

Un-break my heart
Say you'll love me again
Undo this hurt you caused
When you walked out the door
And walked out of my life
Un-cry these tears
I cried so many nights
Un-break my heart
My heart"
