Two centuries of natural history – from the epic journeys of pioneering naturalists to the breakthroughs making headlines today – have inspired and expanded one of the greatest ideas of modern science: evolution. Encounter the many amazing creatures and the researchers and scientists whose achievements sparked a revolution that changed, our perception of the living world and our place within it.

Can technology allow us to work smarter instead of harder to meet people’s energy needs? The city of Austin proposes to lead the nation in developing and deploying smart grid technology that sends energy where it is needed most, allows household appliances to communicate and distribute demand, and provides other efficient solutions. Learn more about smart grids – what they are, why they’re cool – and the future of Austin’s energy.

Physicists from all over the world, searching for new particles, types of matter and even extra dimensions of space are on the verge of tomorrow’s scientific discoveries. Dr. Sacha Kopp discusses antimatter, Armageddon and more.

Climate change is coming to Texas but how much and in what ways will Texas be affected by global warming? What kind of climate change does Texas need to be ready for? Climate expert Gerald North will discuss climate change and its effect on the Lone Star state and its people.

On June 18, 1983, aboard the Orbiter Challenger, Sally Ride became the first American woman to fly in space. Dr. Ride was not just an astronaut but a pioneer in science education. She discusses the challenges of space, our changing planet and science education in the U.S.

Frozen water on Mars? Dr. Jack Holt shares his discoveries of Martian glaciers long buried under rock debris. These bodies of ice are apparently relics of Mars’ ancient climate and could be an important key to future Mars exploration.

Why do some students learn while some fall behind? What happens in the brain when we learn? Dr. Bob Duke shares research over the past two decades that has deepened our understanding of the fundamental principles of human learning.

Fifty percent of the world’s energy consumption and CO2 emissions come from modern buildings, building trades and construction. Is it possible to greatly reduce our energy use simply by designing buildings differently? What about choice of materials and new – or even ancient – technologies to passively heat, light, and cool buildings?

Agriculture in the U.S. uses millions of pounds of pesticides and herbicides per year. At the same time, many amphibians are ‘feminizing’ – meaning male frogs and toads, among other animals, are producing eggs instead of sperm. Are agricultural chemicals to blame? What are the implications for human fertility and health?

Could there be life on the cold outer planets of our solar system? Dr. Donald Blankenship discusses an unmanned space mission to Europa, one of Jupiter’s moons, which is thought to have an ice-covered ocean that may host exotic life.
