The organism was initially called NLF, for “new life form”. Jean-Michel Claverie and Chantal Abergel, evolutionary biologists at Aix-Marseille University in France, found it in a water sample collected off the coast of Chile, where it seemed to be infecting and killing amoebae. Under a microscope, it appeared as a large, dark spot, about the size of a small bacterial cell.
Later, after the researchers discovered a similar organism in a pond in Australia, they realized that both are viruses — the largest yet found. Each is around 1 micrometre long and 0.5 micrometres across, and their respective genomes top out at 1.9 million and 2.5 million bases — making the viruses larger than many bacteria and even some eukaryotic cells.
But these viruses, described today in Science, are more than mere record-breakers — they also hint at unknown parts of the tree of life. Just 7% of their genes match those in existing databases.
“What the hell is going on with the other genes?” asks Claverie. “This opens a Pandora’s box. What kinds of discoveries are going to come from studying the contents?” The researchers call these giants Pandoraviruses.

Dr Greger suggests a diet change that reduces saturated fats. A vegetarian diet reduces the risk of fat storage that produces cellulite. So if you eat less animal products, you are healthier, thinner and better looking (less cellulite). Your choice ladies.

Biologists briefly brought the extinct Pyrenean ibex back to life in 2003 by creating a clone from a frozen tissue sample harvested before the goat’s entire population vanished in 2000. The clone survived just seven minutes after birth, but it gave scientists hope that “de-extinction,” once a pipedream, could become a reality.
Ten years later, a group of researchers and conservationists gathered in Washington, D.C., today (March 15) for a forum called TEDxDeExtinction, hosted by the National Geographic Society, to talk about how to revive extinct animals, from the Tasmanian tiger and the saber-toothed tiger to the woolly mammoth and the North American passenger pigeon.

“Directed evolution” may save our polluted planet. At least, chemical engineer Dr. Frances Arnold sees it that way.
The recent National Medal of Technology and Innovation recipient is credited with pioneering the technique of directed evolution, a method used to engineer proteins or evolve certain organisms, leading to the revolutionary production of renewable fuels and chemicals, among other results.

A pair of RNA-like molecules can spontaneously assemble into gene-length chains, chemists in the United States and Spain report. Billions of years ago, related molecules may have created a rudimentary form of genetic information that eventually led to the evolution of RNA and life itself, the researchers say. Although it’s likely to be difficult, if not impossible, to prove whether similar proto-RNAs were present at the dawn of life, the researchers are working to see if the proto-RNAs can indeed faithfully encode information and evolve toward RNA.
.
Researchers have thought that RNA, the molecular cousin of the DNA that encodes our genes, may have played a role in the initial evolution of life. Shown here is an image of a DNA strand.
