http://thegreateststorynevertold.tv/ Since the mid-20th century, the world has only ever heard one side of an incredible story. The story of a boy from an ordinary family whose ambition it was to become an artist, but who instead became a drifter. His destiny however was not to drift into the awaiting oblivion, but to rise to the greatest heights of power, eventually to become one of the most influential men who ever lived. Now for the first time, here is a documented account of a story many believe to be… The Greatest Story NEVER Told!

Dark Matter - 02:30 Host Neil deGrasse Tyson reports from a half mile underground in an abandoned mine, where scientists are using special detectors to look for evidence of a ghostly substance that they believe makes up most of the matter of the universe—a hypothetical entity called dark matter.Of Mice And Memory - 17:05Researchers have found that mice with induced memory loss are able to retrieve memories after they spend time in enriched environments that stimulate mental activity. What's more, these scientists have identified a drug that has a similar effect. It appears to promote gene activity in the brain that is important in memory. These insights may lead to a better understanding of dementia and memory-impairment disorders such as Alzheimer's.While scientists are yet in the early stages of translating this research in mice into treatments for humans, it's striking that many Alzheimer's sufferers temporarily improve in an activity-rich environment, providing a tantalizing clue to further research and possible therapies.Profile : Hany Farid - 30:00Is seeing believing? In this age of easy photo manipulation, sometimes you have to call in a digital detective to be sure. Enter Hany Farid, professor of computer science at Dartmouth College, who developed a program that can unmask photo tampering by analyzing light sources and other subtle features in an image. Wisdom Of The Crowds - 43:55In the early 1900s, British scientist Sir Francis Galton thought he was proving the ignorance of the masses when he noted that no one got the right answer at a country-fair competition in which entrants were asked to guess the exact weight of an ox. What Galton failed to realize was that the median of all the guesses produced close to the right answer—and showed the "wisdom of the crowd."Cosmic Perspective & Dark Matter - 49:15Turkish subtitles will be added soon.No copyright intended, all the copyrights belong to PBS NOVA.http://www.pbs.org/wgbh/nova/sciencenow/Support PBS! http://www.shoppbs.org/family/index.jsp?categoryId=11580318&ab=NOVAscienceNOWOr donate: http://www.pbs.org/about/support-our-mission/

Personal DNA Testing - 01:40NOVA scienceNOW examines the realm of personal DNA testing. It describes the latest tests, which look for single-nucleotide polymorphisms (SNPs). These single-letter differences in DNA sequence make humans unique from one another but may also predispose people to certain diseases. The video also discusses the Personal Genome Project, an extension of the Human Genome Project aimed at determining the root causes of many common diseases. The Personal Genome Project takes into account personal genomics as well as lifestyle information, such as one's living environment, habits, and behaviors.Art Authentication - 14:25Vincent van Gogh has inspired several talented artists to turn their hands to forgery. Can computers be used to identify which works are really his? To find out, NOVA scienceNOW, working in cooperation with the Van Gogh Museum in Amsterdam, commissioned an expert in art reconstruction to make a meticulous copy of a van Gogh painting. Then, we challenged three different computer teams—from Princeton, Penn State, and Maastricht universities—to see if they could spot the imitation in a group that included five genuine van Goghs.Capturing Carbon - 27:45How did an eighth-grader's science fair project inspire a new way to tackle rising levels of carbon dioxide in the atmosphere? Claire Lackner's father Klaus, a geophysicist at Columbia University, had a brainstorm after he saw how Claire used an aquarium pump to capture carbon dioxide in the air. A decade later, Dr. Lackner is testing a product inspired by his daughter's vision.Profile: Pardis Sabeti - 40:30By day, Pardis Sabeti is a Harvard evolutionary geneticist who is using an algorithm she developed to try to understand how the malaria parasite develops resistance to the drugs we use to fight it. By night, Sabeti and her band Thousand Days play the clubs around greater Boston. In this NOVA scienceNOW segment, meet the Iranian-born Sabeti in both of her very different worlds.Cosmic Perspective & Bad News - 49:00Turkish subtitles will be added soon.No copyright intended, all the copyrights belong to PBS NOVA.http://www.pbs.org/wgbh/nova/sciencenow/Support PBS! http://www.shoppbs.org/family/index.jsp?categoryId=11580318&ab=NOVAscienceNOWOr donate: http://www.pbs.org/about/support-our-mission/

Bird Brains - 02:00Birds have an undeserved reputation for low brainpower. In fact, they produce one of the most glorious phenomena in nature: birdsong. How do their brains do it? And what does this skill tell us about the evolution of another remarkable phenomenon, human language?Research on an Australian songbird called the zebra finch is shedding light on babbling in babies, stuttering, and the neuronal processes of understanding and making sounds. Evidence of the evolution of birdsong as well as human speech may lie in our genes, including an intriguing gene called FOXP2.Space Storms - 15:30The aurora borealis, or northern lights, is one of nature's most spectacular performances, a celestial ballet of light dancing across the night sky. But the same forces that power this dazzling display can overwhelm power grids, fry electrical systems in satellites, even expose astronauts to deadly amounts of radiation. What to do? An unusual space mission aims to find out.Profile: Yoky Matsuoka - 26:05Growing up in Japan, Yoky Matsuoka was on her way to becoming a world-class tennis player. When injuries ended her tennis dreams, she turned to another early interest: robotics. Twenty years later Matsuoka is now a leader in the emerging field of neurobotics, hard at work creating robot technology that can help disabled persons.Smart Bridges - 38:45After the Minneapolis Interstate 35 bridge collapsed in 2007, millions became nervous about crossing long highway spans.

Leeches - 02:00Leeches can consume seven or eight times their body weight in blood, says leech expert Mark Siddall. As doctors are now discovering, this talent, along with the bloodsuckers' natural anti-coagulant, can benefit patients who have had fingers or toes reattached. Find out how in this video segment.SETI: The Search for ET - 13:50In 1960 an inquisitive astronomer named Frank Drake aimed a radio telescope at a couple of nearby stars and started listening. Nearly 50 years later we're still listening, and SETI—the Search for Extraterrestrial Intelligence—has just expanded to begin the systematic survey of millions of star systems for signs of advanced civilizations. The Allen Telescope will eventually comprise 350 dish antennas, all working in unison to answer the question: Are we alone?Stem Cells Breakthrough - 25:55In a July 2008 update on the controversial subject of stem cell research, NOVA scienceNOW explores a potentially revolutionary development. Japanese researcher Shinya Yamanaka first discovered how to take ordinary skin cells from an adult mouse, turn back their genetic clock, and transform them into the equivalent of embryonic stem cells. Yamanaka called them Induced Pluripotent Stem (iPS) cells. He and other biomedical researchers can now create human iPS cells without using human embryos, thus bypassing a political and ethical stumbling block that has hampered stem cell research.Medical scientists are eager to explore the full potential of stem cells, which can grow into almost any type of cell in the body. Now they are a step closer to using this promising technology to treat a wide range of diseases. One experiment has already used iPS cells to cure mice of a sickle cell condition. Major hurdles remain, but the discovery of iPS cells is so important that Yamanaka is being touted as a candidate for a Nobel PrizeProfile: Edith Widder - 40:15Go for a deep-sea dive with a marine biologist who is seeing things never before recorded on the ocean floor. Edie Widder studies marine bioluminescence, the biochemical emission of light by ocean animals. Bioluminescent animals can light up the murky depths, and Widder is doing some lighting of her own with an innovative camera system called the "Eye in the Sea." It uses a wavelength of light invisible to sea creatures to catch them unawares.Widder's research and innovation of new technologies have won her a MacArthur "genius" grant, which will help support her work at the Ocean Research and Conservation Association, an organization she cofounded. Her passion for studying marine life is matched by her drive to help ensure its conservation and the health of marine ecosystems worldwide.Cosmic Perspective & SETI - 49:25Turkish subtitles will be added soon.No copyright intended, all the copyrights belong to PBS NOVA.http://www.pbs.org/wgbh/nova/sciencenow/Support PBS! http://www.shoppbs.org/family/index.jsp?categoryId=11580318&ab=NOVAscienceNOWOr donate: http://www.pbs.org/about/support-our-mission/

Phoenix Mars Lander - 01:55With behind-the-scenes access, NOVA scienceNOW covers the Mars lander Phoenix's thrilling descent to the martian surface and its critical early days of operations. Phoenix will dig into the permafrost to obtain samples of martian dirt and ice for analysis in onboard labs, seeking any evidence that the Red Planet might once have sustained microbial life—or perhaps still does.Brain Trauma - 14:20Knocks to the head may seem funny in cartoons, sports replays, and YouTube videos, but even minor head injuries often lead to serious concussions. A concussion may leave no trace on a conventional MRI scan yet cause permanent memory loss, attention problems, and depression. NOVA scienceNOW investigates promising new leads in understanding this puzzling condition, which affects millions of people in the U.S., including many high-school and college athletes who suffer concussions yet are encouraged to return to the playing field.Mammoth Mystery - 26:13In 1962, paleontologists uncovered the rarest of Ice Age fossils in the Nebraska badlands: two complete male mammoths locked in a death grip by their 12-foot-long tusks. What made them fight? And why did they die together? Following forensic clues, paleontologists determine the sex and age of the mammoths, the time of year of their deadly battle, and how their violent clash doomed them.Profile: Judah Folkman - 38:30Dr. Judah Folkman, who died in 2008 at age 74, was a giant in the field of cancer research. He wasn't always considered a trailblazer, however. In the 1970s, when he first proposed that cancer depends critically on new blood vessel growth, or angiogenesis, other medical researchers ridiculed his ideas. But Folkman proved his theory of angiogenesis, and today it has led not just to cancer therapies but also to treatments for other diseases of abnormal blood vessel growth, such as macular degeneration.Cosmic Perspective & Happy Birthday NASA - 49:35Turkish subtitles will be added soon.No copyright intended, all the copyrights belong to PBS NOVA.http://www.pbs.org/wgbh/nova/sciencenow/Support PBS! http://www.shoppbs.org/family/index.jsp?categoryId=11580318&ab=NOVAscienceNOWOr donate: http://www.pbs.org/about/support-our-mission/

Diamond Factory - 02:15A blindfolded Neil deGrasse Tyson is led to a top-secret "diamond farm" to investigate breakthroughs in the engineering of artificial diamonds. Indistinguishable from the real thing, these glittering creations may one day adorn more than ring fingers. They could replace silicon transistors in everything from supercomputers to high-speed electric trains.Anthrax Investigation - 16:50Amazingly, researchers were able to trace the strain of anthrax used in the deadly 2001 attacks to its source flask. How? By relying on a revolutionary technique that highlights key mutations in a microbial strain. In the future, such genetic fingerprinting can help pinpoint source microbes responsible for everything from food-borne poisonings to deadly health epidemics.Auto-Tune - 31:00NOVA scienceNOW talks to the engineers behind Auto-Tune, the pitch-correction software that turns sour notes into sweet ones. Professional musicians from Madonna to Snoop Dogg use Auto-Tune, but can the software turn host Neil deGrasse Tyson into a singing star?Profile: Luis von Ahn - 37:55Growing up in Guatemala, where his family owned a candy factory, computer scientist Luis von Ahn seemed like your average video-game-addicted, TV-watching kid. But von Ahn is now heralded as one of the brains behind CAPTCHA, the world's most ubiquitous computer security program. He is also a professor at Carnegie Mellon University, where he works to combine the best skills of humans and computers. His projects capitalize on the countless hours we humans waste at our keyboards, and he and his students are turning the stuff of games into valuable tools for transforming the Internet.Cosmic Perspective & Carbon - 48:55Turkish subtitles will be added soon.No copyright intended, all the copyrights belong to PBS NOVA.http://www.pbs.org/wgbh/nova/sciencenow/Support PBS! http://www.shoppbs.org/family/index.jsp?categoryId=11580318&ab=NOVAscienceNOWOr donate: http://www.pbs.org/about/support-our-mission/

Hunt for Alien Earths - 02:00NOVA scienceNOW visits astronomers who may be on the brink of finding "another Earth" outside our solar system but within our Milky Way galaxy. A new planet-hunting machine, the Kepler telescope, is at their disposal. This and other ingenious technologies could finally answer the age-old question: Are we alone?Art Authentication - 14:42Vincent van Gogh has inspired several talented artists to turn their hands to forgery. Can computers be used to identify which works are really his?

She has discovered why it makes evolutionary sense for the males of this species, a type of black widow, to make the ultimate sacrifice, what she calls "adaptive suicide."Autism Genes - 36:41Rudy Tanzi, a pioneer in discovering genes for Alzheimer's disease, is turning his attention to autism. Using gene chips that can scan up to a million genetic markers across the entire human genome, Tanzi and others are on the hunt for the genetic key to a heartbreaking disorder that seems to come out of nowhere and yet affects millions of children and their families.Cosmic Perspective & Planet Hunters - 49:31Turkish subtitles will be added soon.No copyright intended, all the copyrights belong to PBS NOVA.http://www.pbs.org/wgbh/nova/sciencenow/Support PBS! http://www.shoppbs.org/family/index.jsp?categoryId=11580318&ab=NOVAscienceNOWOr donate: http://www.pbs.org/about/support-our-mission/

Marathon Mouse - 1:50Ron Evans at the Salk Institute says that his lab's genetically modified mice can "run the pants off" their control counterparts. Studying these marathon mice helped his team develop drugs that increase muscle mass and endurance. Such "exercise in a pill" could aid kids with muscular dystrophy, elderly people who are bedridden, and others suffering from muscle disorders. But it also poses the risk of abuse by athletes looking for a leg up.Dinosaur Plague - 14:21What killed off the dinosaurs? Over the years, experts have suggested everything from global climate change to a spate of massive volcanic eruptions to the most widely accepted culprit: an asteroid that unleashed global devastation. But as correspondent Chad Cohen reports, some scientists believe the giant reptiles might have been taken down by something almost too tiny to see.Profile: Franklin Chang-Diaz - 29:26Franklin Chang-Díaz was NASA's first Latin-American to go into space, and he's been there seven times, which ties the record. But his greatest accomplishment may be yet to come. The Costa Rican native is designing a plasma-based rocket engine that he believes will revolutionize space travel, putting our entire solar system at our disposal.Space Storms - 40:16The aurora borealis, or northern lights, is one of nature's most spectacular performances, a celestial ballet of light dancing across the night sky. But the same forces that power this dazzling display can overwhelm power grids, fry electrical systems in satellites, even expose astronauts to deadly amounts of radiation. What to do?

The Science of Picky Eaters - 02:00What makes a dish taste good to some people and terrible to others? Why do many people, particularly many kids, find broccoli and spinach unbearably bitter? Neil deGrasse Tyson, whose mother says he was always a good eater, sets out to investigate the science behind our sense of taste. It turns out that genetics largely determine our taste, and specific genes may provide new excuses for picky eaters.Smart Marine Mammals - 14:47Scientists studying the behavior and intelligence of seals, sea lions, and other captive marine mammals at the University of California's Long Marine Lab say that these animals are challenging long-held assumptions about what makes humans different from other animals. Correspondent Ziya Tong discovers just what the researchers mean after she meets some of their gregarious pinniped students.Profile: Sangeeta Bhatia - 25:22Biomedical engineer Sangeeta Bhatia comes from a line of enterprising women—her mother was one of the first women in India to receive an M.B.A. With her own Ph.D. and M.D., Bhatia is a tissue engineer at MIT. She builds unique microlivers to study disease and test drugs, and her work may someday lead to artificial organs for transplant.While a student at MIT, Bhatia started an outreach program to get girls into labs—wearing spacesuits, working with lasers, and loving science. Now, as a mother, Bhatia is encouraging her two young daughters to see science as a creative, exciting endeavor.
