    It looks like physics works differently in different places. If so, everything we think we know about the cosmos may be wrong

How ancient plants and soil fungi turned Earth green - 0 views

  •  
    ScienceDaily (Nov. 2, 2010) - New research by scientists at the University of Sheffield has shed light on how Earth's first plants began to colonize the land over 470 million years ago by forming a partnership with soil fungi.

Positive well-being to higher telomerase: Psychological changes from meditation trainin... - 0 views

  •  
    ScienceDaily (Nov. 4, 2010) - Positive psychological changes that occur during meditation training are associated with greater telomerase activity, according to researchers at the University of California, Davis, and the University of California, San Francisco. The study is the first to link positive well-being to higher telomerase, an enzyme important for the long-term health of cells in the body.

The Most Dangerous Drug - Hit & Run : Reason Magazine - 0 views

  •  
    A new study in The Lancet rates the harmfulness of 20 psychoactive drugs according to 16 criteria and finds that alcohol comes out on top. Although that conclusion is generating headlines, it is not at all surprising, since alcohol is, by several important measures (including acute toxicity, impairment of driving ability, and the long-term health effects of heavy use), the most dangerous widely used intoxicant, and its abuse is also associated with violence, family breakdown, and social estrangement. A group of British drug experts gathered by the Independent Scientific Committee on Drugs (ISCD) rated alcohol higher than most or all of the other drugs for health damage, mortality, impairment of mental functioning, accidental injury, economic cost, loss of relationships, and negative impact on community. Over all, alcohol rated 72 points on a 100-point scale, compared to 55 for heroin, 54 for crack cocaine, and 33 for methamphetamine. Cannabis got a middling score of 20, while MDMA (Ecstasy), LSD, and psilocybin mushrooms were at the low end, with ratings of 9, 7, and 6, respectively.

Lies, Damned Lies, and Medical Science - Magazine - The Atlantic - 0 views

  •  
    Much of what medical researchers conclude in their studies is misleading, exaggerated, or flat-out wrong. So why are doctors-to a striking extent-still drawing upon misinformation in their everyday practice? Dr. John Ioannidis has spent his career challenging his peers by exposing their bad science.

Fermilab is Building a 'Holometer' to Determine Once and For All Whether Reality Is Jus... - 0 views

  •  
    Researchers at Fermilab are building a "holometer" so they can disprove everything you thought you knew about the universe. More specifically, they are trying to either prove or disprove the somewhat mind-bending notion that the third dimension doesn't exist at all, and that the 3-D universe we think we live in is nothing more than a hologram. To do so, they are building the most precise clock ever created.

Berkeley Lab scientists open electrical link to living cells | KurzweilAI - 0 views

  •  
    Scientists with the Lawrence Berkeley National Laboratory (Berkeley Lab) have designed an electrical link to living cells engineered to shuttle electrons across a cell's membrane to an external acceptor along a well-defined path. This direct channel could yield cells that can read and respond to electronic signals, electronics capable of self-replication and repair, or efficiently transfer sunlight into electricity.

Technology Review: Blogs: arXiv blog: Highlights from the Gallery of Fluid Motion - 9 views

  •  
    The best of the bunch (so far) for the 2010 American Physical Society's Gallery of Fluid Motion Each year, the Fluid Dynamics division of the American Physical Society holds a conference. This year, the meeting is in Long Beach, California, in November. One of the highlights is the impressive set of videos of fluid motion that the delegates put together. These videos have already begun to appear on the arViv in impressive numbers. Videos are an effective and increasingly popular way of publishing research. Expect to see more like this. But there are clearly better ways to make them available other than as downloads from the arXiv or as videos in a room in Long Beach. One obvious option is to make them available on streaming websites such as YouTube andVimeo. As far as I can tell, they are not available like this. Another is to create a website that showcases them in advance, to make it a global, web-based event. Many of the videos are superb. Not only could they command a bigger audience, they deserve it. If plans are afoot to make the Gallery of Fluid Motion a bigger event, then great. If not, shame! Here is my selection of the highlights this year.

YouTube - The Known Universe by AMNH - 0 views

  •  
    The Known Universe takes viewers from the Himalayas through our atmosphere and the inky black of space to the afterglow of the Big Bang. Every star, planet, and quasar seen in the film is possible because of the world's most complete four-dimensional map of the universe, the Digital Universe Atlas that is maintained and updated by astrophysicists at the American Museum of Natural History. The new film, created by the Museum,  is part of an exhibition, Visions of the Cosmos: From the Milky Ocean to an Evolving Universe, at the Rubin Museum of Art in Manhattan through May 2010.     Data: Digital Universe, American Museum of Natural History  http://www.haydenplanetarium.org/universe/    Visualization Software:  Uniview by SCISS    Director: Carter Emmart  Curator: Ben R. Oppenheimer  Producer: Michael Hoffman  Executive Producer: Ro Kinzler  Co-Executive Producer: Martin Brauen  Manager, Digital Universe Atlas: Brian Abbott    Music: Suke Cerulo    For more information visit http://www.amnh.org

Collective intelligence in small teams | KurzweilAI - 0 views

  •  
    A new study co-authored by MIT researchers documents the existence of collective intelligence among groups of people who cooperate well, showing that such intelligence extends beyond the cognitive abilities of the groups' individual members, and that the tendency to cooperate effectively is linked to the number of women in a group.
