Host Peter Tonge visits with Paul Rogers of Stonehedge Nursery who offers tips on growing culinary herbs from seeds indoors on a windowsill. Also shows how to identify soil type with a basic 10-minute test. Looks at some of the organic additives you can use to improve your soil. Originally aired as an episode of "The Good Green Earth."

National Geographic Explorer Paul Sereno and his team are looking for the complete skeleton of Nigersaurus. They traveled to the Niger hoping to find enough bones to construct a complete replica of the dinosaur from the ground up. They begin their search in the dinosaur graveyard of the Sahara Desert. Segment of video from Wild Chronicles Series.
National Geographic Explorer-in-Residence Paul Sereno is usually digging up dinosaur bones. But Sereno was walking through the Sahara in northern Niger when he found a nearly 10,000-year-old human skull. This discovery lead Sereno to imagine the green Sahara that was their home. Segment of video from Wild Chronicles Series.
Imagine if there were electronics able to prevent epileptic seizures before they happen, or electronics that could be placed on the surface of a beating heart to monitor its functions. The problem is that such devices are a tough fit. Body tissue is soft and pliable while conventional circuits can be hard and brittle--at least until now. Materials scientist John Rogers at the University of Illinois Urbana-Champaign is working to develop elastic electronics.
Chemist Paul Edmiston’s search for a new way to detect explosives at airports led to the creation Osorb. A swellable, organically-modified silica, or glass, capable of absorbing oil and other contaminants from water. Osorb has become the principal product of a company called ABSMaterials, where Edmiston is now chief scientist. With support from the National Science Foundation, Edmiston and his colleagues at ABSMaterials are developing water remediation technologies for cities and industries. ABSMaterials is creating formulas to address various contaminants, including hydrocarbons, pharmaceuticals, pesticides, herbicides, chlorinated solvents, and endocrine disruptors.

Patients who have suffered devastating facial injuries sometimes go to great lengths to hide themselves from public view. At the University of Illinois at Urbana-Champaign, civil and mechanical engineer Glaucio Paulino saw the possibilities of combining engineering and medical skills to tackle the complex challenge of facial reconstruction.
