US evolutionary biologist David Sloan Wilson was in the UK last month to talk about the field study he has been running for six years in his home town of Binghamton, New York State, in economic decline. "There are things that are natural to a field biologist, and one of them is to study species in their natural environment," explains Wilson. "Jane Goodall [famous for her studies of chimpanzees] has the Gombe Stream Park [Tanzania] and Darwin's finches are studied in the Galápagos, so why don't we study humans in the context of their everyday life?" In 2006, Wilson decided to study the 47,000 residents of Binghamton. Biologist wants to 'make the world a better place' | Society

The Six Epochs of Life mural was commissioned by Martine and Bina Rothblatt in the summer of 2008 to be painted on a bare concrete wall at Estate Marbina Abenaki’s Terasem Center of Critical Consciousness. The primary wish that the Rothblatts had for the mural was that it illustrate the Six Epochs of Life described in chapter one of Ray Kurzweil’s The Singularity Is Near. Use the viewer below to pan across and zoom in on the mural panorama. The Six Epochs of Life — a mural by Nick Mayer inspired by Ray Kurzweil’s The Singularity Is Near
CORVALLIS, Ore. – A team of scientists has documented for the first time that animals can and do consume Archaea – a type of single-celled microorganism thought to be among the most abundant life forms on Earth. Archaea that consume the greenhouse gas methane were in turn eaten by worms living at deep-sea cold seeps off Costa Rica and the West Coast of the United States. Archaea perform many key ecosystem services including being involved with nitrogen cycling, and they are known to be the main mechanism by which marine methane is kept out of the atmosphere. The finding of this new study adds a wrinkle to scientific understanding of greenhouse gas cycles. Results of the study, which was funded by the National Science Foundation, have been published online in the International Society for Microbial Ecology Journal, a subsidiary of the journal Nature. Scientists document first consumption of abundant life form, Archaea
Strange Life Found in Underwater Caves | How Life Evolved on Earth, Alien Life Evolution | Extreme Life on Earth, Strangest Life on Earth Clues to how life evolved, not only on this planet but also possibly on alien worlds, might be found in underwater caves in the Bahamas, researchers say. The caves in question are called "blue holes," so-named because from the air, their entrances appear circular in shape, with different shades of blue water in and around them. There are estimated to be more than 1,000 such caves in the Bahamas, the greatest concentration of blue holes in the world. "It's really incredible to be swimming down a passage that no one has ever been in before, to experience that thrill of discovery," said researcher Tom Iliffe, a marine biologist at Texas A&M University at Galveston. "At the bottom of a cave, there's no telling what might be around the next corner." Iliffe and his colleagues examined three inland blue holes in the Bahamas.
The discovery of microbes in any icy lava tube in Oregon raises hope that similar microorganisms could survive in the very similar conditions to be found on Mars. The microbes are coping with near-freezing temperatures and low levels of oxygen, and can even grow in the absence of organic food. Their metabolism is driven by the oxidation of iron from olivine, a common volcanic mineral found in the rocks of the lava tube. Microbes found thriving in Mars-like conditions

BBC Radio 4 Programmes - Frontiers, Acts of Creation The creation of an artificial cell by scientist and entrepreneur Craig Venter shows what synthetic biology is capable of. But others want to go much further - recreating life from scratch, or redesigning it at the most fundamental level. In his Harvard Lab, Nobel laureate Jack Szostak is forcing strands of DNA's cousin RNA to compete with each other in a Darwinian struggle for existence. At Manchester University, John Sutherland is seeing whether the raw materials of biochemistry can form themselves in the kinds of puddles that might have existed on Earth 4 billion years ago.
Artificial life and the RNA world by Matthew Cobb Two things come together from earlier this year. First, there was a lot of argument here, in the Times Literary Supplement and elsewhere over Stephen C.
