A pesar de terminar con el labio hinchado la pasé de maravilla. Creo que saber algo sobre física en realidad ayuda a volar la mochila cohete. Funciona según el mismo principio que un cohete (la tercera ley de Newton), pero a diferencia del transbordador, no llevas tu propio propulsor contigo. En cambio, una moto de agua bombea agua desde el lago hasta 60 litros por segundo. Luego se dispara a través de las boquillas a aproximadamente 15 metros por segundo, creando 1800 Newton de fuerza, el equivalente a unos 150 extintores de incendios. Esto puede producir una aceleración de alrededor de 1,5 Gs sobre mí.

The Golden Mole is completely blind, but that has not hindered this deadly predator. It's found an ingenious way of pinpointing prey in the desert using it's exceptional hearing, and for best effect, it must burrow under the sand. This clip was taken from the Deserts episode of Planet Earth II.

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.

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.
The quills of North American porcupines have microscopic backward-facing barbs on the tips. Those barbs make the quills slide in easy but very difficult to remove.
Researchers at Harvard are looking to porcupine quills for inspiration in designing a new type of surgical staple that would also use tiny barbs to keep itself lodged into the patient’s skin. This helps because traditional staples curve in under the skin to keep the staple in place. This creates more damage and can provide a place for bacteria to infect the wound.
--- How do porcupines defend themselves?
If threatened, a porcupine will bristle, raising its quills. The quills are densest in an area on the porcupine's back called the rosette. The quills are coated in a grease secreted by the porcupine’s skin. When the porcupine exposes its quills it releases a musky odor unique to porcupines that serves as a warning.
The porcupine turns so that it’s head faces away from the attacker and chatters its teeth to make an audible warning. If that’s not enough, he porcupine will use its muscular tail, covered in quills, to slap their attacker if they get too close.
--- Do porcupines shoot their quills?
Porcupines do not shoot their quills out. That’s a myth. Porcupine quills are held by their skin in a way that makes them difficult to fall out unless pushed in first, usually by contact with an attacker. The tail moves so quickly that it can appear that it is shooting the quills out.

Alfalfa leafcutting bees are way better at pollinating alfalfa flowers than honeybees. They don’t mind getting thwacked in the face by the spring-loaded blooms. And that's good, because hungry cows depend on their hard work to make milk.

Sure, cows are important. But next time you eat ice cream, thank a bee.
Every summer, alfalfa leafcutting bees pollinate alfalfa in an intricate process that gets them thwacked by the flowers when they release the pollen that allows the plants to make seeds. The bees’ hard work came to fruition last week when growers in California finished harvesting the alfalfa seeds that will be grown to make nutritious hay for dairy cows.
This is how it works.
To produce alfalfa seeds, farmers let their plants grow until they bloom. They need help pollinating the tiny purple flowers, so that the female and male parts of the flower can come together and produce fertile seeds. That’s where the grayish, easygoing alfalfa leafcutting bees come in. Seed growers in California release the bees – known simply as cutters – in June and they work hard for a month.
Alfalfa’s flowers keep their reproductive organs hidden away inside a boat-shaped bottom petal called the keel petal, which is held closed by a thin membrane that creates a spring mechanism.
Cutter bees come up to the flower looking for nectar and pollen to feed on. When they land on the flower, the membrane holding the keel petal breaks and the long reproductive structure pops right up and smacks the upper petal or the bee, releasing its yellow pollen. This process is called “tripping the flower.”
When the flower is tripped, pollen falls on its female reproductive organ and fertilizes it; bees also carry pollen away on their hairy bodies and help fertilize other flowers. In a few weeks, each flower turns into a curly pod with seven to 10 seeds growing inside.
Cutters trip 80 percent of flowers they visit, compared to honeybees, which only trip about 10 percent.
---
--- What kind of a plant is alfalfa?
Alfalfa is a legume, like beans and chickpeas. Other legumes also hold their reproductive organs within a keel petal.
--- What do bees use leaves for?
Alfalfa leafcutting bees and other leafcutter bees cut leaf and petal pieces to build their nest inside a hole, such as a nook and cranny in a log. Alfalfa farmers provide bees with holes in styrofoam boards.

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

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.

Las extraordinarias propiedades del Aerogel se deben en gran parte a su estructura. El aerogel es sólido, pero a nanoescala tiene una estructura de malla o esponja. Los pilares de su estructura son de tamaño nanométrico, al igual que los poros de unos 20 nanómetros de ancho. Esto hace que el aerogel de sílice sea increíblemente liviano, transparente y absorbente. (alguna vez fue el sólido más liviano pero ahora ha sido reemplazado por el aerogel de grafeno)
Una pieza de aerogel del tamaño de un cubo de hielo tiene una superficie interna aproximadamente igual a la mitad de un campo de futbol. El aerogel se usa en cajas de museo de alta gama para regular la humedad. Además, ayuda a mantener el vacío en los sismómetros de Mars Insight: absorbe la humedad y otros volátiles desgasificados que provienen de la propia nave espacial. También proponen utilizarlos como insecticida físico al "secar los insectos" reduciendo la necesidad de pesticidas químicos y tóxicos.

Los vikingos sufrieron muchas dificultades en el norte de Europa: inviernos largos y fríos, pero sobre todo, padecieron la falta de luz solar. Por suerte, tenían al bacalao.

Cuando hice un video sobre las vitaminas, pensé que la historia se trataría principalmente de píldoras suplementarias, si deberíamos tomarlas o no y cómo se hacen. Pero lo que descubrí es que las vitaminas tienen una historia notable, que afecta muchos más aspectos de nuestras vidas. Por ejemplo, los vikingos necesitaban una fuente de vitamina D para sobrevivir los oscuros meses de invierno y para que sus hijos desarrollaran huesos fuertes y saludables, evitando el raquitismo.

THE SHORT FILM
Director: Jim Yukich
Primary Production Location: Los Angeles, California
Michael Jackson's short film for "Liberian Girl" was the eighth of nine short films produced for recordings from Bad, one of the best selling albums of all time. While "Liberian Girl" was not released as a single in the United States, it was released as a single internationally and reached the Top 20 in five countries throughout Europe, including the United Kingdom, the Netherlands, France, Switzerland and Ireland (where it reached No. 1). In the United Kingdom, "Liberian Girl" was Michael's ninth Top 40 single from Bad, a record for one album.
The song's humorous short film starts with black and white footage of an African port town, before a transition to color, where a production assistant's clapboard reveals the "town" is a soundstage. On that set, dozens of Michael's friends and collaborators make small talk, joke and wait around with one question on their minds: where is Michael? At the short film's conclusion, when everyone converges on the set, it is revealed that Michael was behind the camera the whole time, laughing as he descends from a camera crane and saying, "Okay everyone, that's a wrap!"
Three dozen actors, musicians and celebrities can be seen in the short film, including Malcolm-Jamal Warner, Paula Abdul, Whoopi Goldberg, Bad producer Quincy Jones, John Travolta and Olivia Newton-John (making their first on-screen appearance together since 1978's Grease), Steven Spielberg, "Weird Al" Yankovic, Suzanne Somers, Lou Ferrigno, Don King, illusionist David Copperfield, Richard Dreyfuss, Danny Glover and Dan Aykroyd. During the video, a mysterious person wearing bandages can be spotted; in the short film's end credits, he is credited simply as "?"
