Scientists have found the world’s oldest known human blood in the 5,300 year-old mummy known as the Iceman.

Baughman’s lab creates tiny artificial muscles. They spin carbon nanotubes into yarn stronger than steel yet so light it almost floats in air.

Richard Baraniuk is unlocking the secrets of nature’s best camouflage artists – the cephalopods.

The USA Science and Engineering Festival, expected to draw a million visitors to Washington’s National Mall in October 2010. Dr. Johnson explained what it’s all about.

Listen to Elke Anklam talk about the possible pros and cons of using nanotechnology in food products.

Using nanotechnology, DeSimone has developed a way to engineer drug particles so they target only diseased regions of the body and avoid healthy cells.

This Harvard chemist said that, to understand a plant, you have to look inside its cells.

He said nanotechnology – the control of matter at the atomic scale – can make our animal food systems safer.

Jennifer Kuzma talks about the impact of nanotechnology – the engineering of materials at the atomic scale – on the food we eat.

Strickland said, ” The specific idea was to incorporate sensors into pesticide spray, so that you can monitor how well the crop field was sprayed for pests, or while adding nutrients to the crop field.”

Rosalyn Berne studies the ethics of nanotechnology. She said we don’t understand what happens to nano products used in agriculture, at the point when that product filled with nano particles washes into the soil.

Hear Nick Bostrom, director of the Future of Humanity Institute at Oxford University talk about transhumanism — the belief that human life will be radically enhanced in the future.

Calestous Juma of Harvard University reports that some of the best engineers in the world are coming together to tackle environmental problems in order to increase food and water supplies in the developing world.

Nanotechnology has the potential to help us produce more energy, says Shell scientist Sergio Kapusta. Hear Kapusta talk about the applications of nanotechnology to renewable energy.

In the future, an elite class might be able to enhance their physical bodies and their senses. Rosalyn Berne of the University of Virginia talks about how nanotechnology might redefine what it means to be human.

He said humans have experienced catastrophes in the past, but that the events of this century could determine the survival of our species.

Listen to Jochen Weiss of the University of Hohenheim speak about using nanotechnology to add omega-3 fatty acids to a variety of foods.

David Carroll is getting closer to creating a new kind of solar cell, one made of plastic that would be lightweight, flexible, and more efficient than the more familiar silicon solar cells.
