DNA (deoxyribonucleic acid) is the gigantic molecule which is used to encode genetic information for all life on Earth. DNA molecules consists of a long strand of base molecules arranged in the form of a double helix. The bases are adenine, guanine, cytosine, and thymine, often abbreviated as A, G, C, and T. What we ordinarily think of as "our" DNA, because it controls most aspects of our physical appearance, is also known as "nuclear DNA", because every cell in our bodies contains two copies of it in the cell nucleus.

"Where do we come from?" This has been one of the fundamental questions asked by humans for thousands of years. Physical anthropologists have been providing an answer for over a hundred years by studying morphological characteristics, such as skull shape, of the fossilised remains of our human and proto-human ancestors.

For the last 15 years or so, molecular anthropologists have been comparing the DNA of living humans of diverse origins to build evolutionary trees. Mutations occur in our DNA at a regular rate and will often be passed along to our children. It is these differences (polymorphisms) that, on a genotypic level, make us all unique and analysis of these differences will show how closely we are related. However, different approaches used by molecular and physical anthropologists have led to opposing views on how modern humans evolved from our archaic ancestors.

Calm down, you haven't overslept by a couple of months or anything, as the Wolfdale we're talking about here is in fact simply a 2.33GHz engineering sample of the forthcoming dual-core processor.

It had been a tick since we'd heard from I-O Data's LCD department, but its latest offering steps it up from the 22-inch version seen earlier this year by expanding the screen real estate and adding new inputs.

We glimpsed the future of the Bravia XBR LCD line back in March when Sony showed off the Japanese-only X2550s, and now it looks like that premonition was dead-on, as the nine new Bravias introduced today feature Sony's x.v.Color wide color gamut system, 10-bit 1080p panels, Bravia Engine upscaler, the oh-so-popular XMB crossbar interface, and [...]

Sony didn't limit its Bravia updates to LCDs today, as it also dropped five new SXRD rear-projection units.

The SXRDs also get Sony's new PhotoTV HD [...]
