The world's electric grids are aging and vulnerable. Now, engineers are making a dangerous trek to prove there is a better way to bring power to the people. Engineers make a dangerous trek across the Himalayas to bring power to a remote monastery.
The Ebola outbreak of 2014 almost brought the world to its knees, but this crisis has mobilized scientists and researchers, paving the way for new treatments and vaccines. From antibiotics and vaccines to computer programs that predict how viruses will spread, new lifesaving tools will be used to fight a wide range of viruses in the near future, including HIV, influenza, dengue fever, malaria, and a host of other killer diseases.

Scientific advancements are challenging the concept of what it means to be human. Technology embedded in our bodies is fairly common: artificial limbs, pacemakers. But new research is taking us beyond replacement parts and into a new realm that is changing the nature of the human body and the human mind. Will the fusion of biology and technology change how we think, how we feel, how we experience the world?

After millennia of speculation about what goes on inside the human brain, we now have the tools to explore its hidden reaches. These tools are leading to research that may help those suffering from afflictions such as epilepsy and Alzheimer's disease. They are also shedding light on the mystery of consciousness and what makes us who we are.

In recent years, close study of the aging process has opened up new ways that could help us all live healthier for longer. Can we move beyond treating individual diseases, and instead treat the aging process itself? But would a longer life necessarily be a better life? A loose-knit group of researchers believe the real breakthrough is extending our health span - the period of life spent free of disease.

We are surrounded by clean, raw energy waiting to be tapped - energy that could eventually replace fossil fuels. Finding new ways to harness the energy around us takes a rare breed of scientist-engineers: men and women with a combination of technical skill, imagination, and unwavering focus. If we act now, developments in energy production could avert disaster and usher in a new era of clean, safe energy.

California is on the brink of an apocalypse. The state faces a future of drought that will cost billions in lost farm revenue and thousands of jobs. But the challenges facing the state are not unique: All over the world, governments are struggling with bigger populations and a diminishing supply of freshwater. Innovators across the globe are seeking solutions in emergent technologies to prevent a planet-wide water crisis.

Phenomena of incredible speed that we cannot see, captured in stunning detail using high-speed cameras. Watch the mechanics of dogs in motion (do their feet touch the ground?) Learn how a cat’s tongue works, experience the shockwaves of explosions, see the dynamics of fire -- and more!
Imagine a world without the power to capture or transmit sound. Journey with Steven Johnson to the Arcy sur Cure caves in northern France, where he finds the first traces of the desire to record sound — 30,000 years ago. He also learns about the difference that radio made in the civil rights movement and reveals the Hollywood star who designed a WW2 weapon that would make possible the modern cell phone network. During an ultrasound on a pregnant dolphin, he realizes just how big a role sound has played in medicine. The unsung heroes of sound have had an impact on our working lives, race relations, saving lives and the radical alteration of cities.
On Jan. 28, 1986, seven astronauts "slipped the surly bonds of earth to touch the face of God." America's space program was never the same.

We cannot see things like the movement of a sponge because its movements are too slow. But with specialized photography we can see imperceptibly slow and fast movements. See the dynamics of a child's first steps, rainfall, nocturnal animals and butterflies in flight-and the incredible archer fish.
An examination of the varying uses being made of the huge amount of information now available in databases. In Los Angeles, police officers are taking part in an experiment to predict crime before it even happens, one City of London trader believes he has found the secret of making billions with mathematics, and astronomers in South Africa are attempting to catalogue the entire universe.
Uncovering what is left of Hitler's ambitious structures which were built in a bid for world domination, beginning with a look at the Atlantic Wall. Created in order to protect Europe from an Allied invasion it stretches thousands of kilometres from France to Norway, and on D-Day the fortifications were put to the ultimate test.
