If Russian billionaire Dmitry Itskov has his way, the human lifespan will soon no longer depend on the limitations of the human body. Itskov, a Russian tycoon and former media mogul, is the founder of the 2045 Project — a venture that seeks to replace flesh-and-blood bodies with robotic avatars, each one uploaded with the contents of a human brain. The goal: to extend human lives by hundreds or thousands of years, if not indefinitely.

Gamers capture more information faster for visual decision-making. Hours spent at the video gaming console not only train a player's hands to work the buttons on the controller, they probably also train the brain to make better and faster use of visual input, according to Duke University researchers. "Gamers see the world differently," said Greg Appelbaum, an assistant professor of psychiatry in the Duke School of Medicine. "They are able to extract more information from a visual scene." (...) This study, which appears in the June edition of the journal Attention, Perception and Psychophysics, was supported by grants from the Army Research Office (54528LS), the Department of Homeland Security (HSHQDC-08-C-00100), DARPA (D12AP00025-002) and Nike Inc.

Early Earth was not very hospitable when it came to jump starting life. In fact, new research shows that life on Earth may have come from out of this world. Lawrence Livermore scientist Nir Goldman and University of Ontario Institute of Technology colleague Isaac Tamblyn (a former LLNL postdoc) found that icy comets that crashed into Earth millions of years ago could have produced life building organic compounds, including the building blocks of proteins and nucleobases pairs of DNA and RNA. Comets contain a variety of simple molecules, such as water, ammonia, methanol and carbon dioxide, and an impact event with a planetary surface would provide an abundant supply of energy to drive chemical reactions.
