The language of life is about to expand its vocabulary. An international team of researchers discovered that the body's copying machine for DNA works in the same way for manmade, artificial building blocks of DNA as it does for the natural kind. If scientists find artificial DNA building blocks work well and are safe to use, the extra building materials could create DNA that codes for new molecules that the body can't make now.
Artificial DNA Copies Just Like the Real Thing
Plasma fusion becomes a reality?
Published time: April 02, 2012 21:51 Edited time: April 03, 2012 01:51 Reuters / Alexander Demianchuk Scientists in a New Jersey laboratory say they are close to a major breakthrough in the field of fusion that they predict will soon allow for an unlimited source of the cheapest, cleanest and safest energy ever. Researchers at Lawrenceville Plasma Physics in Middlesex, NJ have published the results of their recent work in the Physics of Plasmas journal last week, and expect one of their next rounds of testing to finally tackle an issue of energy procurement that would rival anything already available. In their latest breakthrough, fusion researchers at the lab say that they’ve successfully heated and confined an ionized gas at record temperatures which would be high enough to allow for the nuclear fusion of certain elements, including hydrogen and boron.
Houston: video of Dawkins award to Hitchens
A good 30-minute video of Richard Dawkins giving his eponymous award to Christopher Hitchens at the Texas Freethought Convention, and Hitch’s response to the award, has finally become available. You can find the link here . Richard’s introduction is touching and funny; Hitch’s response, which he struggles against his illness to deliver, is deeply moving and inspiring.

Scientists from Cern have repeated their finding of neutrinos travelling faster than the speed of light.
Superposition is a principle of quantum theory that describes a challenging concept about the nature and behavior of matter and forces at the sub-atomic level. The principle of superposition claims that while we do not know what the state of any object is, it is actually in all possible states simultaneously, as long as we don't look to check.
What is superposition? - Definition from Whatis.com

Alexei_Kurakin: The SOFT-NET theory
"SOFT-NET" stands for the self-organizing fractal theory (SOFT) and nonequilibrium thermodynamics (NET). One of the key postulates of the SOFT-NET theory posits that everything that exists is a manifestation of the energy/matter comprising and flowing through the Universe. From this perspective, everything is connected to everything else via an all-embracing and all-permeating energy/matter flow, everything is in a flux, and everything changes through the emergence and transformation of energy/matter forms.

Scientists Say California Mega-Quake Imminent
Like a steaming kettle with the top on, pressure is building beneath the surface of California that could unleash a monster earthquake at any time. That's according to a new study from the Scripps Institute of Oceanography. Geologists say Southern California is long overdue for a huge earthquake that could unleash widespread damage.Self-organization
Self-organization is a process where some form of global order or coordination arises out of the local interactions between the components of an initially disordered system.Edward Norton Lorenz
Edward Norton Lorenz (May 23, 1917 – April 16, 2008) [ 1 ] was an American mathematician and meteorologist , and a pioneer of chaos theory . [ 2 ] He discovered the strange attractor notion and coined the term butterfly effect .Belousov–Zhabotinsky reaction
