Janine Benyus: Biomimicry in action

Janine Benyus has a message for inventors: When solving a design problem, look to nature first. There you'll find inspired designs for making things waterproof, aerodynamic, solar-powered and more. Here she reveals dozens of new products that take their cue from nature with spectacular results.

Robert Full: Secrets of movement, from geckos and roaches

Biologist Robert Full shares slo-mo video of some captivating critters. Take a closer look at the spiny legs that allow cockroaches to scuttle across mesh and the nanobristle-packed feet that let geckos to run straight up walls.

David Gallo: The deep oceans: a ribbon of life

David Gallo takes us to some of Earth's darkest, most violent, toxic and beautiful habitats, the valleys and volcanic ridges of the oceans' depths, where life is bizarre, resilient and shockingly abundant. This has the disappearing octopus.

David Gallo: Underwater astonishments

David Gallo shows jaw-dropping footage of amazing sea creatures, including a color-shifting cuttlefish, a perfectly camouflaged octopus, and a Times Square's worth of neon light displays from fish who live in the blackest depths of the ocean.

Juan Enriquez: Decoding the future with genomics 

Scientific discoveries, futurist Juan Enriquez notes, demand a shift in code, and our ability to thrive depends on our mastery of that code. Here, he applies this notion to the field of genomics.

Aubrey de Grey: Why we age and how we can avoid it

Cambridge researcher Aubrey de Grey argues that ageing is merely a disease -- and a curable one at that. Humans age in seven basic ways, he says, all of which can be averted.

I have to ask the question, "What are the simplest organisms that age?" well here is an interesting artical on the common factors of aging in yeast and in mice Technology Review - How Cells Age

Molecular Biology Visualization of DNA

First the DNA Wrapping is animated. The wrapping allows 6 feet of the long DNA molecule to be densely packed into the tiny nucleus of every cell. The process starts when DNA is wrapped around special protein molecules called histones. The combined loop of DNA and protein is called a nuclei zone. Next the nuclei zones are packed into a thread. The end result is fiber known as chromatin. This fiber is looped and coiled yet again leading to the familiar shapes known as chromosomes which can be seen in the nucleus of dividing cells. Chromosomes are not always present - they form around the time cells divide when the two copies of the cell's DNA need to be separated.
Using computer animation based on molecular research we are now able to see how DNA is actually copied in living cells.
An assembly line of amazing biochemical machines are pulling apart the DNA double helix and cranking out a copy of each strand.
