Fate of the Earth [electronic resource]

Explores the delicate balance of the Earth's ecology and humankind's capacity for the destruction of life. Looks at the natural forces that created the universe from the ocean's depths to the distant boundaries of the solar system. Features interviews with scientists, biologists, and ecologists who study the biology of life and discuss the newfound concern for the preservation of the planet. Examines the environmental and human impact on the Earth's ecology, including the greenhouse effect, pollution, dwindling rain forests, and the possibility of nuclear warfare.

Nuclear Energy: The Issues

Nuclear power produces almost a fifth of the world's electricity. Supporters say it is safe, cheap and—best of all—the answer to global warming. Critics say it is not safe, or cheap. And it will not really help with the global warming problem. So who is right? This program presents the arguments for and against, with relevant background information. Issues covered in this program include: radioactive waste: how hazardous is it? Can it be safely stored? How likely is an accident at a nuclear power plant? What could the consequences be? Are nuclear power stations terrorist targets? Does nuclear power encourage the development of nuclear weapons? Is nuclear energy "carbon-free"? Is it the solution to global warming? NB: The science behind nuclear power—what nuclear fission is, how a nuc [...]

Everything and Nothing: Nothing

Part two of the series Everything and Nothing deals with science at the very limits of human perception, where the deepest mysteries of the universe lie. Professor Al-Khalili sets out to answer one very simple question: What is nothing? His journey ends with perhaps the most profound insight about reality that humanity has made. Everything came from nothing.

Better Wine Through Chemistry

The single most important step to making a good wine is fermentation, which is what gives wine its particular taste and alcohol content. Winemakers add yeast—a single-celled fungus—to grape juice, and if all goes well the yeasts rapidly multiply, crowding out other microbes and allowing fermentation to complete in two to three weeks. But sometimes, the yeasts get stuck and don’t fully ferment—a problem that has plagued the wine industry for centuries. Now a team of geneticists and biotechnologists have discovered what triggers "stuck" fermentation, and are bringing winemakers one step closer to perfecting the winemaking process.

Journey of the Universe: An Epic Story of Cosmic, Earth and Human Transformation

TEDTalks: Benjamin Grant—What It Feels Like to See Earth From Space

What the astronauts felt when they saw Earth from space changed them forever. Author and artist Benjamin Grant aims to provoke this same feeling of overwhelming scale and beauty in each of us through a series of stunning satellite images that show the effects human beings are having on the planet. "If we can adopt a more expansive perspective, embrace the truth of what is going on and contemplate the long-term health of our planet, we will create a better, safer and smarter future for our one and only home," Grant says.

Safety on Fire

There are over 80,000 chemicals in use today. The story of TRIS, removed from children's pajamas in the 1970s, illustrates just how hard it is to regulate chemicals, or to even know if they're safe.

Should We Go to Mars? The Big Think

The year 2019 will be the 50th anniversary of the first Moon landing. It was the greatest technological achievement of the 20th century. Since then, NASA’s goal has been to send an astronaut to Mars. But it’s proving far harder than anyone imagined. Some experts believe that human space travel and exploration is critical. But Mars is approximately 140 million miles away, and the effort to land a human on our closest planet risks billions of dollars and the lives of those brave enough to try. Is the possible benefit worth the risk? And is it really achievable?

Speech to Laser to Sound

New technology using a one-color laser may drive future generation of high-tech hearing aids. Scientists are testing a new idea, a device that uses a laser to encode sound in the form of light pulses and then transmit them onto tissues in the ear, which absorb the light and vibrate, inducing sound waves.

Buzz Aldrin

Global Warming and Sea Level Change

Renowned oceanographer and geophysicist Walter Munk talks about the relationship between global warming and sea level change. Professor Munk points out that, contrary to popular belief, the melting of floating ice does not change sea level. It is the melting of land-based ice masses that contributes to a rise in sea level.

Laurent Lesterquit (FR), Lionel Ries (FR-BE), Jean-Luc Issler (FR), Guenter W. Hein (de), Jose-Angel Avila-Rodriguez (ES): Radio Signals for Better Satellite Navigation

Laurent Lestarquit and his international team designed and patented two primary signal innovations for the European GALILEO global navigation satellite system (GNSS). Their signalling technology helps ensure the high accuracy of GALILEO, while saving energy and assuring navigational compatibility and/or interoperability with the US GPS and the Russian GLONASS worldwide GNSS systems. The team's developments also allow the use of legacy and lower end receivers along with the latest high-end satellite navigational devices.

Gene Editing Made Simple and Is There Life on Mars?—Catalyst

CRISPR is a powerful gene-editing technique that is transforming the field of genetics. Faster, easier and cheaper than previous gene modification methods, the dream of treating cancer or curing hereditary gene diseases is one step closure. However, with the power to change DNA come ethical implications. CRISPR gives us the ability to alter the evolution of an entire species. Scientists are excited but are aware that they need to be careful how they use this revolutionary gene editing tool. Graham Phillips goes into the desert on a meteorite hunt. The reason is to investigate the question humanity’s been asking for centuries: is there life on Mars? A group of Monash University geologists believe the insides of meteorites make great habitats for microbes. Just as Earth bugs live insid [...]
