‘Magic mushrooms’ ingredient beneficial to cancer patients, report says – latimes.com

Researchers find psilocybin improved the anxiety and depression of terminal cancer patients for up to six months. The study is considered a first step in restoring the hallucinogen's respectability. By Thomas H. Maugh II, Los Angeles Times September 7, 2010 The psychedelic drug psilocybin, the active ingredient in “magic mushrooms,” can improve mood and reduce anxiety and depression in terminal cancer patients, Los Angeles researchers reported Monday. A single modest dose of the hallucinogen, whose reputation was severely tarnished by widespread nonmedical use in the psychedelic '60s and ethical lapses by researchers such as Timothy Leary, can improve patients' functioning for as long as six months, allowing them to spend their last days with more peace, researchers said. The research was a pilot study involving only 12 patients, but it is viewed as a first step in restoring the drug to respectability.

Recent News on BP Spill Dispersants Reminiscent of Russian Toxic Rain Prediction

Image: Craig Anderson, Flickr Earlier this summer, when the BP Oil Spill was still at the top of the headlines everywhere, Russian predictions of a toxic rain consequent to the BP oil spill were generally dismissed by the scientific community. But the cultural meme, as well as an underlying level of anxiety for Gulf residents, was planted. Now, reports are appearing that raise the spectre of the Russian prediction. Are people living … Read the full story on TreeHugger

Does Focusing on Biodiversity Diminish Nature?

photo: ((brian)) via flickr Unless you’ve just started following environmental issues you’re probably aware that biodiversity is declining so much that the planet is seeing species go extinct at a rate a thousand times historical rates of extinction–and that we’re collectively not do a very good job preventing human activity from accelerating that.

Gates Foundation invests in Monsanto/ Both will profit at expense of small-scale African farmers

Farmers and civil society organizations around the world are outraged by the recent discovery of further connections between the Bill and Melinda Gates Foundation and agribusiness titan Monsanto. Last week, a financial website published the Gates Foundation’s investment portfolio, including 500,000 shares of Monsanto stock with an estimated worth of $23.1 million purchased in the second quarter of 2010 (see the filing with the Securities and Exchange Commission). This marks a substantial increase from its previous holdings, valued at just over $360,000 (see the Foundation’s 2008 990 Form). “The Foundation’s direct investment in Monsanto is problematic on two primary levels,” said Dr. Phil Bereano, University of Washington Professor Emeritus and recognized expert on genetic engineering. “First, Monsanto has a history of blatant disregard for the interests and well-being of small farmers around the world, as well as an appalling environmental track record. The strong connections to Monsanto cast serious doubt on the Foundation’s heavy funding of agricultural development in Africa and purported goal of alleviating poverty and hunger among small-scale farmers. Second, this investment represents an enormous conflict of interests.” Monsanto has already negatively impacted agriculture in African countries. For example, in South Africa in 2009, Monsanto’s genetically modified maize failed to produce kernels and hundreds of farmers were devastated. According to Mariam Mayet, environmental attorney and director of the Africa Centre for Biosafety in Johannesburg, some farmers suffered up to an 80% crop failure. While Monsanto compensated the large-scale farmers to whom it directly sold the faulty product, it gave nothing to the small-scale farmers to whom it had handed out free sachets of seeds. “When the economic power of Gates is coupled with the irresponsibility of Monsanto, the outlook for African smallholders is not very promising,” said Mayet. Monsanto’s aggressive patenting practices have also monopolized control over seed in ways that deny farmers control over their own harvest, going so far as to sue—and bankrupt—farmers for “patent infringement.” News of the Foundation’s recent Monsanto investment has confirmed the misgivings of many farmers and sustainable agriculture advocates in Africa, among them the Kenya Biodiversity Coalition, who commented, “We have long suspected that the founders of AGRA—the Bill and Melinda Gates Foundation—had a long and more intimate affair with Monsanto.” Indeed, according to Travis English, researcher with AGRA Watch, “The Foundation’s ownership of Monsanto stock is emblematic of a deeper, more long-standing involvement with the corporation, particularly in Africa.” In 2008, AGRA Watch, a project of the Seattle-based organization Community Alliance for Global Justice, uncovered many linkages between the Foundation’s grantees and Monsanto. For example, some grantees (in particular about 70% of grantees in Kenya) of the Alliance for a Green Revolution in Africa (AGRA)—considered by the Foundation to be its “African face”—work directly with Monsanto on agricultural development projects. Other prominent links include high-level Foundation staff members who were once senior officials for Monsanto, such as Rob Horsch, formerly Monsanto Vice President of International Development Partnerships and current Senior Program Officer of the Gates Agricultural Development Program. Transnational corporations like Monsanto have been key collaborators with the Foundation and AGRA’s grantees in promoting the spread of industrial agriculture on the continent. This model of production relies on expensive inputs such as chemical fertilizers, genetically modified seeds, and herbicides. Though this package represents enticing market development opportunities for the private sector, many civil society organizations contend it will lead to further displacement of farmers from the land, an actual increase in hunger, and migration to already swollen cities unable to provide employment opportunities. In the words of a representative from the Kenya Biodiversity Coalition, “AGRA is poison for our farming systems and livelihoods. Under the philanthropic banner of greening agriculture, AGRA will eventually eat away what little is left of sustainable small-scale farming in Africa.” A 2008 report initiated by the World Bank and the UN, the International Assessment of Agricultural Knowledge, Science and Technology for Development (IAASTD), promotes alternative solutions to the problems of hunger and poverty that emphasize their social and economic roots. The IAASTD concluded that small-scale agroecological farming is more suitable for the third world than the industrial agricultural model favored by Gates and Monsanto. In a summary of the key findings of IAASTD, the Pesticide Action Network North America (PANNA) emphasizes the report’s warning that “continued reliance on simplistic technological fixes—including transgenic crops—will not reduce persistent hunger and poverty and could exacerbate environmental problems and worsen social inequity.” Furthermore, PANNA explains, “The Assessment’s 21 key findings suggest that small-scale agroecological farming may offer one of the best means to feed the hungry while protecting the planet.” The Gates Foundation has been challenged in the past for its questionable investments; in 2007, the L.A. Times exposed the Foundation for investing in its own grantees and for its “holdings in many companies that have failed tests of social responsibility because of environmental lapses, employment discrimination, disregard for worker rights, or unethical practices.” The Times chastised the Foundation for what it called “blind-eye investing,” with at least 41% of its assets invested in “companies that countered the foundation’s charitable goals or socially-concerned philosophy.” cont. added by: JanforGore

NASA’s Kepler Telescope Detects Possible Earth-Size Planet

August 26, 2010 Telescope Detects Possible Earth-Size Planet By KENNETH CHANG Astronomers are quickly closing in on Earth-size planets elsewhere in the galaxy as they find planetary systems that look more and more like our solar system. Scientists working with NASA’s Kepler satellite reported Thursday that they might have spotted a planet just 1.5 times the diameter of Earth around a Sun-like star 2,000 light-years away. If that planet is made of similar stuff as Earth, its mass would be three to four times as much. “We’re still in the process of confirming this candidate is a planet,” said Matthew Holman, of the Harvard-Smithsonian Center for Astrophysics, during a NASA-sponsored news conference on Thursday. Dr. Holman is the lead author of an article describing the discoveries that the journal Science published on its Web site. This is the first announcement of a candidate Earth-size planet by the Kepler mission, which launched a one-ton orbiter in March 2009 to search for planets like ours. The planet was among more than 700 candidate planets that the team announced spotting in June. The Kepler team also observed, more definitively, two Saturn-size planets around the same star, known as Kepler-9. On Tuesday, a European team reported what may be an even smaller planet, with mass as little as 1.4 times that of Earth, around a star 127 light-years away. In the past 15 years, astronomers have discovered close to 500 such extrasolar planets. At first, they uncovered huge gas giant planets that orbited extremely close to the stars. But as detection methods improved, astronomers began to find planets closer in size to Earth and planetary systems that contain nearly as many planets as our solar system. The Earth-size planet seen by the European astronomers appears to be one of seven circling the star, HD 10180, located in the constellation Hydrus. Christophe Lovis of the University of Geneva, who led the observations, said the group was certain about the existence of five of the planets, all about the size of Neptune, but squeezed into orbits closer to the star than Mars is to the Sun. Dr. Lovis said they were slightly less certain about the smallest planet. “For this one, we have about 1 percent false alarm possibility,” Dr. Lovis said. “For us, 99 percent is just not enough to be completely sure.” The team also tentatively detected a larger, Saturn-size planet farther from the star. Neither of the slightly-bigger-than-Earth planets is Earth-like. Both have orbits very close to their stars that would sear the surfaces. “If one particular word can describe planetary systems today, it’s ‘diverse,’ “ said Douglas N. C. Lin, a professor of astronomy and astrophysics at the University of California, Santa Cruz, who not involved with either team. “Planets are common, and their properties are diverse.” Photo Caption: An artist’s rendering shows the two Saturn-sized planets discovered by NASA’s Kepler mission, which also found a planet sized similarly to Earth. added by: EthicalVegan

If We Can Attribute Natural Disasters to Climate Change, Who Could Victims Sue for Damages?

photo: Samenwerkende Hulpoganisaties via flickr Though it’s de rigueur to say that any single weather event can’t be directly linked to climate change, and it’s true, what if we could determine how much of say massive flooding or a 1000-year heat wave were caused by human-caused warming? Could the victims hold anyone responsible and sue for damages? That’s the question asked in a recent
