Ever wondered how art museums decide if a painting is a fake? Nate meets with Dr. Gregory Smith, a forensic art scientist, to follow a painting they suspect is a forgery. They use everything from x-ray fluorescence to electron microscopy to figure this case out. Part of the "Artrageous With Nate" series.

In this episode, vets use ingenious methods to take an x-ray of a giraffe's giant hoof. Also, an armadillo needs a checkup. Part of "The Wildlife Docs" series.
While Dr. Oakley's family prepares for a birthday surprise, she tends to a sick yak and a pack of sled dogs. She also oversees the care of two orphaned eaglets. Part of the "Wilderness Vet" series.
What are nuclear actin filaments? They are the tiniest first responders that help cells repair damage. Other features in this episode include interventions to help boost coral's resilience to bleaching and chips that help miniature drones navigate. Part of the "4 Awesome Discoveries You Probably Didn't Hear About This Week" series.
Host Emily Graslie travels to the Denver Museum of Nature & Science, and she explores the health sciences collection. Dr. Nicole Garneau is the curator for the exhibit, and Graslie becomes the newest addition to the DNA collection. Part of "The Brain Scoop" series. Please note: This title shows donated human anatomy to the museum collection.
Our Sun is a nuclear reactor converting hydrogen to helium continuously. X-ray and telescopic images reveal the Sun's photosphere and chromosphere, sun spots, solar flares and winds, and prominences. Describes each and its impact on Earth. Covers some of the Sun's mysteries, and projects what will eventually happen to our closest star.
When it comes to ultrafast lasers, Margaret Murnane’s name is one of the best known for her work in this field of science. Since 1999, she has been a professor at the University of Colorado’s National Science Foundation funded JILA Physics Frontier Center, where she and her husband, Henry Kapteyn, pioneer research in ultrafast x-ray science. Part of the Scientists and Engineers On Sofas Series.
Students receive a crash course in the physiology and functioning of their hearts as well as how to keep their hearts healthy. Animations clarify how the heart works to provide oxygen and nutrients to all the tissues and organs of the body. They also detail what can go wrong. The program stresses that even teenagers can show early signs of atherosclerosis and other heart problems. Two cardiologists and a dietitian then pinpoint the main risk factors for an unhealthy heart, including: smoking, abnormal levels of cholesterol, high blood pressure, obesity, diabetes, and physical inactivity.
Part of the "Gunther's ER" series. Beyond the immediate risks to a patient's life, doctors must also identify other bodily damage. Dr. Gunther von Hagens examines the kinds of injuries that can lead to permanent disability if not quickly addressed. Dissecting a female body donor who died after falling from a window, von Hagens locates fractures throughout her skeleton, explains how bones break, and bends a human spine to discover how much force it can withstand before snapping. Also investigates the causes and consequences of brain damage. Recreating head injury to the exposed brain of another cadaver, von Hagens illustrates how the rigid, closely fitting skull can actually damage the brain it is meant to protect. NOTE: Viewer discretion is advised. Contains clinically explicit language and nudity.
Bill Nye takes on Jupiter's deadly radiation. Jupiter produces the radiation equivalent of 100 million X-rays. Nye explains how NASA protects the instruments on the “Juno” spacecraft from this incredibly harsh environment. Part of the “Why With Nye” series.
From a table at a bar, on a corner of the city of Buenos Aires, we discovered the nature of some of the “wave motion phenomenon” that surrounds us. Some of these were radio and TV waves or the ones from the microwave in the kitchen, solar light, X-rays and cosmic waves.
Beginning with Alchemy's attempt to find the recipe for gold, scientists have strived to unearth the basic building blocks of our world. These building blocks became smaller and smaller as scientists including Isaac Newton and Albert Einstein studied the world. From elements, to the atom, to subatomic particles, the study of our natural world has led to inventions both deadly and fantastic, including X-Rays, MRIs, calculus, and the atomic bomb.
If the sun instantly switched off like a light bulb, it would take almost 8 and a half minutes before humans on Earth realized what happened. Light travels at the fastest speed there is, but it still takes almost 500 seconds to get to Earth. This means the sunlight that reaches Earth is old. How is that possible? It is due to the concept of random walks. Part of the “It’s Okay to Be Smart” series.
In less than a second a sandfish lizard can dig its way into the sand and disappear. The sandfish's slithering moves are inspiring new robotic moves that could one day help search and rescue crews find survivors in piles of rubble left from disasters. With support from the National Science Foundation, physicist Daniel Goldman and his team at Georgia Tech are studying the lizard’s movements, using x-rays to track it underground. Their findings will contribute to engineering designs for deployable robots that could one day help canine search and rescue teams find survivors more quickly.
As scientists delved deep into the atom, into the very heart of matter, they unraveled nature's most shocking secrets. They had to abandon everything they believed in and create a whole new science, which today underpins the whole of physics, chemistry, biology, and maybe even life itself. Tells a story of great geniuses, like Albert Einstein and Werner Heisenberg who were driven by their thirst for knowledge and glory. It's a story of false starts and conflicts, ambition, and revelation, a story which leads us through some of the most exciting and exhilarating ideas ever conceived of by the human race.
Biologist Ken Dial has documented in extraordinary detail how birds are put together and the mechanics of how they take to the air. With support from the National Science Foundation, Dial and his team at the University of Montana Flight Lab use x-rays and high speed video to better understand the mechanics of bird flight. Dial’s more than 2,000 flight hours as a pilot in a wide range of aircraft adds another dimension to his research. Perhaps, by mimicking what birds have learned over millions of years, aircraft wings could change shape to accommodate both slow and fast flight, or a helicopter propeller’s shape might be altered to be more efficient.
The manta ray is the largest ray in the ocean. They have have cephalic lobes, or flaps, which help the manta funnel food into its mouth. These animals can even leap out of the water. Now that's one weird animal. Part of the "Weird Animal" series.
Digit’s Digi-Fizz is an overnight hit in Perfectamundo, but the toy causes pollution. The team must find a solution to the unexpected problem. Part of the "Cyberchase" series.
Dr. Ronald Evans describes how fat communicates with muscle and how diet and exercise influence that relationship. Part of the 2004 Howard Hughes Holiday Lecture Series.
Xenon is a chemical element with the symbol Xe and atomic number 54. It is a colorless, dense, odorless noble gas found in Earth's atmosphere in trace amounts.
