Since the invention of the wheel we have striven to make great machines that would make our lives more productive and efficient, however we will almost certainly never invent a machine as efficient as the human body. Each component of the machine is given in depth attention with the same clarity and insightful touch you have come to expect from the Eyewitness books. There are over 206 bones, half of which are in the hands and feet. A total of 640 muscles contract and exert pressure, working together with our skeleton to turn power and strength into movement and precision. Our bodies are incredibly resilient machines, and conversely life is very fragile. After all, unlike any other, this machine can reproduce itself.

Behind the scenes of news coverage during the pandemic. Follow the work of the professional press in a fight against denialism.
In an era of throw-away ease, convenience has cost us our well-being. Plastics have been found inside our bodies— in our colons, our brains, and even in mothers’ developing wombs. Scientists around the country are sounding the alarm, but without public buy-in, there is little that can be done. How much evidence do we need before we decide to take action?
There are endless gruesome ways that the world could end; through nasty, natural disasters or because of some man-made abomination. From maniac killer robots and super volcanoes, to an alien invasion and mutant psycho humans, all options are covered in Ten Ways the World Will End.
Unmasks fraudulent cover-ups, wild speculations, and deceitful myths that have been presented as the absolute "facts" of evolution. Should evolutionism, the foundational faith of eastern mystical thought, be taught in schools as science, when Creationism, the foundational belief of Judeo-Christianity, has been expelled?
The use of embryonic stem cells has ignited fierce debate across the spiritual and political spectrum. But what if we could create manmade stem cells - or find super cells in adults that could forever replace embryonic cells and remove the controversy? Today, we are on the brink of a new era - an age where we may be able to cure our bodies of any illness. Stephen HAWKING has spent his life exploring the mysteries of the cosmos, now there is another universe that fascinates him - the one hidden inside our bodies - our own personal galaxies of cells.
In The Womb is a 2005 National Geographic Channel documentary that focus on studying and showing the development of the embryo in the uterus. The show makes extensive use of Computer-generated imagery to recreate the real stages of the process.
Dr. Helen Caldicott is the most prominent anti-nuclear activist in the world. She's been featured on CNN, 60 Minutes, CBC and Democracy Now. In the 80s, Helen Caldicott campaigned against nuclear weapons testing in the pacific (still responsible today for the majority of tritium we're exposed to), and against the notion of a winnable nuclear war. She was nominated for a Nobel Peace Prize for her efforts. She has always made inaccurate statements regarding civilian nuclear power. But, since the Fukushima-Diachii radiation release has caused (and is projected to cause) zero fatalities... http://www.unis.unvienna.org/unis/en/... ...her tone has changed when speaking to supporters. This has not been acknowledged by prime-time media, as they continue to use her as a source. Any person or media outlet should check Caldicott's history of statements (on any subject) against a domain expert before using her as a source.
A global nightmare is unfolding as farmers and scientists stand at a crossroads questioning the impacts of pesticides and herbicides on human health. At the center of this controversy is glyphosate, the primary active ingredient in Monsanto’s Roundup, the most widely used herbicide in the world. Glyphosate was recently identified as a possible cancer causing agent and is now found in breast milk, baby food, wine and 80% of food grown in the United States. Why is glyphosate filtering into so many facets of our daily lives? And why are countries banning glyphosate while the United States uses more of it than any other country in the world? Children Of The Vine will peel back the curtain on the flawed regulatory practices that are causing more harm than good to public health while also revealing the scary science behind toxic farming practices. In the end, this solution driven documentary will highlight more sustainable large scale farming practices capable of feeding the world.
Most people fully accept paranormal and pseudoscientific claims without critique as they are promoted by the mass media. Here Be Dragons offers a toolbox for recognizing and understanding the dangers of pseudoscience, and appreciation for the reality-based benefits offered by real science.
Many geneticists and archaeologists have long surmised that human life began in Africa. Dr. Spencer Wells, one of a group of scientists studying the origin of human life, offers evidence and theories to support such a thesis in this PBS special. He claims that Africa was populated by only a few thousand people that some deserted their homeland in a conquest that has resulted in global domination.
In 1858 Charles Darwin struggles to publish one of the most controversial scientific theories ever conceived, while he and his wife Emma confront family tragedy.
William Shatner presents a light-hearted look at how the "Star Trek" TV series have influenced and inspired today's technologies, including: cell phones, medical imaging, computers and software, SETI, MP3 players and iPods, virtual reality, and spaceship propulsion.
Trees talk, know family ties and care for their young? Is this too fantastic to be true? German forester Peter Wohlleben and scientist Suzanne Simard have been observing and investigating the communication between trees over decades. And their findings are most astounding.
The Dream Is Alive takes you into space alongside the astronauts on the space shuttle. Share with them the delights of zero gravity while working, eating and sleeping in orbit around the Earth. Float as never before over the towering Andes, the boot of Italy, Egypt and the Nile. Witness firsthand a tension-filled satellite capture and repair and the historic first spacewalk by an American woman.
A breathtaking adventure across five continents and through time to reveal nature's most vital secret. Watch a flying fox gorge itself on a midnight snack of figs. Climb into the prickly jaws of insect-eating plants. Witness a mantis disguised as a flower petal lure its prey to doom.
The Hobbit Enigma examines one of the greatest controversies in science today: what did scientists find when they uncovered the tiny, human-like skeleton of a strange creature, known to many as the Hobbit, on the Indonesian island of Flores in 2003?
Evolutionary biologist Professor Armand Leroi believes data science can transform the pop world. He gathers a team of scientists and researchers to analyse over 50 years of UK chart music. Can algorithms find the secret to pop success? When the results are in, Armand teams up with hit producer Trevor Horn. Using machine-learning techniques, Armand and Trevor try to take a song by unsigned artist Nike Jemiyo and turn it into a potential chart-topper.
Fed Up blows the lid off everything we thought we knew about food and weight loss, revealing a 30-year campaign by the food industry, aided by the U.S. government, to mislead and confuse the American public, resulting in one of the largest health epidemics in history.
In 1962, spurred by the Cold War, President John F. Kennedy famously made the bold proclamation that NASA would send astronauts to the moon by the end of the decade, not because it was easy, but because it was a challenge. The Space Race inspired a generation to pursue careers in science and technology, but as the balance of world power shifted, interest in space exploration declined. "Fight for Space" serves as an urgent call to re-awaken our sense of wonder and discovery.
As society tackles the problem of feeding our expanding population safely and sustainably, a schism has arisen between scientists and consumers, motivated by fear and distrust. Food Evolution, narrated by Neil deGrasse Tyson, explores the polarized debate surrounding GMOs. Looking at the real-world application of food science in the past and present, the film argues for sound science and open-mindedness in a culture that increasingly shows resistance to both.
