Scavengers in the Yellowstone, home to over 400 species, can gorge on nearly 40 tons of rotting elk during harsh winters. It's a dirty job, but someone's got to be nature's janitors. Casey is setting up a carcass stakeout to discover what happens to all the Yellowstone wildlife after death. Since turkey vultures can smell a carcass up to 12 miles away, he uses them to help him find animal carcasses to observe how they are devoured and by which ravenous creature.
Ravaged by looters, earthquakes and erosion, the Step Pyramid of Saqqara is falling apart. Can experts win the race to save this precious pyramid and preserve its treasures?
It contains 99.9 percent of all the matter in our solar system and sheds hot plasma at nearly a million miles an hour. The temperature at its core is a staggering 27 million degrees Fahrenheit. It convulses, it blazes, it sings. You know it as the sun. Scientists know it as one of the most amazing physics laboratories in the universe. Now, with the help of new spacecraft and Earth-based telescopes, scientists are seeing the sun as they never have before and even recreating what happens at its very center in labs here on Earth. Their work will help us understand aspects of the sun that have puzzled scientists for decades. But more critically, it may help us predict and track solar storms that have the power to zap our power grid, shut down telecommunications, and ground global air travel for days, weeks, or even longer. Such storms have happened before—but never in the modern era of satellite communication. "Secrets of the Sun" reveals a bright new dawn in our understanding of our nearest star—one that might help keep our planet from going dark.
A natural history film or wildlife film is a documentary film about animals, plants, or other non-human living creatures, usually concentrating on film taken.
What begins as a star’s cataclysmic explosion in a violent supernova results in one of the most mysterious phenomena in our universe: a black hole. Black holes are the makings of science fiction, with fantasies of tunnel passageways that travel through space and time dominating the imagination. Nothing survives a black hole; it's gravitational pull twists space and time into a furious knot so strong that not even light can escape, making the likelihood of locating a passageway inside almost impossible. Are black holes a rare freak of nature or does the universe hide many of these mysterious phenomena? 125 billion galaxies make up the visible universe, with every major galaxy housing a black hole. Indeed, even our own Milky Way harbours a super-massive black hole, 50 million kilometres wide at the very centre of the galaxy. What role do black holes play in attracting matter together within the spider’s web of gas and galaxies? And, with their voracious appetites, what’s to prevent a black hole from wiping out solar systems like our own?

The Fabric of the Cosmos, a four-hour series based on the book by renowned physicist and author Brian Greene, takes us to the frontiers of physics to see how scientists are piecing together the most complete picture yet of space, time, and the universe.
With each step, audiences will discover that just beneath the surface of our everyday experience lies a world we'd hardly recognize - a startling world far stranger and more wondrous than anyone expected.
Brian Greene is going to let you in on a secret: We've all been deceived. Our perceptions of time and space have led us astray.
Much of what we thought we knew about our universe - that the past has already happened and the future is yet to be, that space is just an empty void, that our universe is the only universe that exists - just might be wrong.
Interweaving provocative theories, experiments, and stories with crystal-clear explanations and imaginative metaphors like those that defined the groundbreaking and highly acclaimed series The Elegant Universe, The Fabric of the Cosmos aims to be the most compelling, visual, and comprehensive picture of modern physics ever seen on television.

Salt is salt, right? When you go to the grocery store to replenish your supply, you probably expect to see just a few varieties, like iodized salt (what most of us use as "table salt") and kosher salt (a coarse salt popular with chefs). But you might also find things like "sel gris" and "fleur de sel." Some gourmets claim that these salts taste different from iodized salt and give additional flavor to foods seasoned with them.
Even if you try not to use much salt, it's almost impossible to avoid it. There are five tastes that all people are able to experience -- bitter, sweet, sour, salty and umami (meaning "delicious and savory taste" in Japanese). Only "salty" is directly related to a substance that we need to consume in order for our bodies to function correctly. Because of this need, humans and animals have a built-in taste for salt.
Le parc national de Glacier (Glacier National Park) est un parc national américain situé dans l'État américain du Montana. Fondé en 1910 et d'une superficie de 4 101 km2, il est bordé au nord par les provinces canadiennes de l'Alberta et de la Colombie-Britannique.
Le parc, qui est constitué de zones montagneuses abritant des dizaines de glaciers, des centaines de lacs et des milliers d'espèces animales et végétales, est l'un des écosystèmes les mieux préservés du pays. Il fait partie d'un écosystème protégé plus étendu (44 000 km2) nommé « Écosystème de la couronne du continent ». Avec le parc national canadien des Lacs-Waterton, il forme depuis 1932 le parc international de la paix Waterton-Glacier. Cette région composée de deux parcs a été désignée par l'UNESCO réserve de biosphère en 1976 et patrimoine mondial en 19954.
Le parc est parcouru par la célèbre route Going-to-the-Sun Road qui franchit le Continental Divide tout en permettant aux visiteurs d'entrer au cœur de forêts denses et de prairies alpines3. Cette route ainsi que cinq hôtels datant du début du xxe siècle sont classés National Historic Landmarks alors que 350 autres constructions font partie du registre national des lieux historiques.
The life cycle of an animal refers to the stages through which the average specimen goes during the entire period that extends from its birth to its eventual death. Studying and knowing about an animal’s normal life cycle gives researchers and enthusiasts important insights and foundations on which to plan and base their efforts, particularly in the sphere of conservation.

Tiger cub (4 days)
At birth, the tiger weighs between 780 and 1 600 grams (averaging just over one kilogram) after a gestation period of about 3.5 months. They will stay hidden and protected in the comfy den that their mother prepared before their birth for the first eight weeks of their lives They are nursed by their mother who will gradually begin to introduce solids when the cubs are between six and eight weeks old.
Cannabis, commonly known as marijuana and by numerous other names, is a preparation of the cannabis plant intended for use as a psychoactive drug and as medicine. Pharmacologically, the principal psychoactive constituent of cannabis is tetrahydrocannabinol (THC); it is one of 483 known compounds in the plant, including at least 84 other cannabinoids, such as cannabidiol (CBD), cannabinol (CBN), tetrahydrocannabivarin (THCV),] and cannabigerol (CBG).
Cannabis is often consumed for its psychoactive and physiological effects, which can include heightened mood or euphoria, relaxation, and an increase in appetite. Unwanted side-effects can sometimes include a decrease in short-term memory, dry mouth, impaired motor skills, reddening of the eyes, and feelings of paranoia or anxiety.

Around 350 BC, Plato wrote about a beautiful island in the Atlantic Ocean that went under the ocean waves in one day and one night. It took two books to describe the history and details of this almost magical island. For years people have been looking for this mysterious lost city, Atlantis. 
Gautama Buddha, the historical Buddha, lived between 563 and 483 BC in the area known now as the Indo-Nepalese region. As a bodhisattva, he had passed through thousands of existences before coming to Earth for his ultimate transmigration.
This last lifetime he began as a son of the King of the realm Sakya, Sudhodana, who ruled at Kapilavastu, in Ancient India on the border of present-day Nepal, and was born in a village called Lumbini into the warrior tribe called the Sakyas (from where he derived the title Sakyamuni, meaning "Sage of the Sakyas").
According to ancient tradition, Queen Maya, his mother, first had a dream of a beautiful white elephant coming down into her womb, and this was interpreted as a sign that the Buddha, or a universal emperor, was about to be born. When her time came, Queen Maya went into the garden and gave painless birth to the bodhisattva. He immediately walked, spoke, and was recei
In the Kruger National Park there is a hunting force that rivals anything else in Africa: a lion pride, 26 members strong!
Despite the females’ hunting prowess, nine adolescent males dominate every kill. Bigger and stronger, they bully their way to the best spots on the carcass. The pride’s two powerful males could easily enforce discipline, but with them away on patrol, the unruly youngsters are running riot.
When eight strong lionesses split from the megapride, food pressure mounts as the remaining females struggle to cater to their sons’ growing demands. Unfocused, uncoordinated and ineffective hunters, the youngsters offer little support to ease the strain.
When a lioness is severely injured during a hippo hunt, the adult females call to the pride males for help. The males' visits may be infrequent but as the head of the family it’s their duty to protect the females and respond if help is needed.
During a heated food fight, they drive three juveniles from the pride forever. A new attitude grips the remaining youngsters; they begin to help on the hunts and succeed in bringing down prey. As time marches on, pride dynamics change again. New cubs are welcomed into the family and the pride males return home.
This is Lion Army - a real life soap opera that tells the stor

Debtocracy (2011) - Public Domain Universe - Aris Chatzistefanou & Katerina Kitidi
For the first time in Greece, a documentary produced by the audience. "Debtocracy" seeks the causes of the debt crisis and proposes solutions sidelined by the government and the dominant media. The documentary is distributed online under creative commons licence since April 6, 2011, officially subtitled in six languages (English, French, German, Italian, Spanish and European Portuguese).
Aris Chatzistefanou and Katerina Kitidi discuss with economists, journalists and intellectuals from all over the world, who describe the steps that led Greece to the current debt trap --to debtocracy. The documentary follows the course of countries like Ecuador, which created Audit Commissions, and tracks the similar process in Greece.
Destroying the Earth is harder than you may have been led to believe.
You've seen the action movies where the bad guy threatens to destroy the Earth. You've heard people on the news claiming that the next nuclear war or cutting down rainforests or persisting in releasing hideous quantities of pollution into the atmosphere threatens to end the world.
Fools.
The Earth was built to last. It is a 4,550,000,000-year-old, 5,973,600,000,000,000,000,000-tonne ball of iron. It has taken more devastating asteroid hits in its lifetime than you've had hot dinners, and lo, it still orbits merrily.
So my first piece of advice to you, dear would-be Earth-destroyer: Do not think this will be easy.
The Hubble Space Telescope has explored the creation of stars and planets, the glory of supernovas and the formation of super massive black holes, charted dark matter and forever changed our understanding of reality itself.

ABSTRACT. Here we weave together interviews conducted by the author with three prominent figures
in the world of Ramanujan's mathematics, George Andrews, Bruce Berndt and Ken Ono. The article
describes Andrews's discovery of the "lost" notebook, Andrews and Berndt's effort of proving and
editing Ramanujan's notes, and recent breakthroughs by Ono and others carrying certain important
aspects of the Indian mathematician's work into the future. Also presented are historical details related
to Ramanujan and his mathematics, perspectives on the impact of his work in contemporary
mathematics, and a number of interesting personal anecdotes from Andrews, Berndt and Ono.
In Star Wars, the bars are bustling with all types of alien creatures. And then, of course, there’s Yoda and Chewbacca. Recently, renowned scientist Stephen Hawking stated that he too believes aliens exist: “To my mathematical brain, the numbers alone make thinking about aliens perfectly rational.”
Hawking thinks we should be cautious about interacting with aliens — that they might raid Earth’s resources, take our ores, and then move on like pirates. “I imagine they might exist in massive ships, having used up all the resources from their home planet. Such advanced aliens would perhaps become nomads, looking to conquer and colonize whatever planets they can reach.”
Karl Heinrich Marx (prononcé, en allemand de Berlin, [kaːɐ̯l ˈhaɪnʀɪç ˈmaːɐ̯ks ]), né le 5 mai 1818 à Trèves en Rhénanie et mort le 14 mars 1883 à Londres, est un historien, journaliste, philosophe, économiste, sociologue, essayiste et théoricien révolutionnaire socialiste et communiste allemand.
Il est connu pour sa conception matérialiste de l'histoire, sa description des rouages du capitalisme, et pour son activité révolutionnaire au sein des organisations ouvrières en Europe. Il a notamment participé à l'Association internationale des travailleurs. L'ensemble des courants de pensées inspirés des travaux de Marx est désigné sous le nom de marxisme. Il a eu une grande influence sur le développement ultérieur de la sociologie. Ses travaux ont influencé de façon considérable le xxe siècle, au cours duquel de nombreux mouvements révolutionnaires se sont réclamés de sa pensée.

The biological and geological future of the Earth can be extrapolated based upon the estimated effects of several long-term influences. These include the chemistry at the Earth's surface, the rate of cooling of the planet's interior, the gravitational interactions with other objects in the Solar System, and a steady increase in the Sun's luminosity. An uncertain factor in this extrapolation is the ongoing influence of technology introduced by humans, such as geoengineering, which could cause significant changes to the planet. The current biotic crisis[5] is being caused by technology[6] and the effects may last for up to five million years.[7] In turn, technology may result in the extinction of humanity, leaving the planet to gradually return to a slower evolutionary pace resulting solely from long-term natural processes.

Lions are the only cats that live in groups, which are called prides. Prides are family units that may include up to three males, a dozen or so females, and their young. All of a pride's lionesses are related, and female cubs typically stay with the group as they age. Young males eventually leave and establish their own prides btiony taking over a group headed by another male.
