Harvard Controls The Minds of Worms…With Lasers! (video
The CoLBeRT system uses lasers (left) to control genetically altered roundworms (right). I love cutting edge science, but sometimes it can seem nefarious enough to make a James Bond villain squeal in delight. Researchers at Harvard University have designed a laser system that can control your mind…or at least the mind of a roundworm. These scientists were able to affect the nervous system of a genetically altered C. elegans roundworm by shining lasers on its neurons – allowing them to make it travel in the direction they wanted, paralyze it in place, or even induce it into laying eggs! While previous experiments could affect C. elegans in a similar way, the Harvard team controlled their roundworms while still letting them move freely. In other words, even if the worms tried to run away the mind control laser could still track them down and make them do its bidding.

Nigeria: UN Confirms Massive Oil Pollution in Niger Delta
Photo: UNEP Sampling the effects of oil pollution. The oil company Shell has had a disastrous impact on the human rights of the people living in the Niger Delta in Nigeria, said Amnesty International, responding to a UN report on the effects of oil pollution in Ogoniland in the Delta region. The report from the United Nations Environment Programme is the first of its kind in Nigeria and based on two years of in-depth scientific research. It found that oil contamination is widespread and severe, and that people in the Niger Delta have been exposed for decades.
Thursday’s report by the United Nations Environmental Programme (UNEP) into the state of oil pollution in Nigeria’s Ogoniland region revealed that the situation is much, much worse than Nigeria or the oil industry has ever acknowledged. The report was a monster, involving 4,000 samples analysed, 142 groundwater monitoring wells drilled, 264 formal community meetings conducted, and 780 boreholes monitored.
A brief look: UN says Nigerian oil pollution worse than first thought
Oil giant Shell has had a disastrous impact on the human rights of the people living in the Niger Delta in Nigeria, said Amnesty International. It was responding to a United Nation (UN) report on the effects of oil pollution in Ogoniland in the Delta region. The Environmental Rights Action/Friends of the Earth Nigeria (ERA/FoEN) has also called for the creation of a $100 billion Environmental Restoration Fund for the Niger Delta. The report from the UN environment programme is the first of its kind in Nigeria and based on two years of in-depth scientific research.
UN confirms massive oil pollution in Nigeria
4 August 2011 – The environmental restoration of Nigeria’s Ogoniland oil region could prove to be the world’s most wide-ranging and long-term oil clean-up exercise ever, if contaminated drinking water, land, creeks and other ecosystems are to be brought back to full health, according to a United Nations report released today.

Unbearable Legacies: The Politics of Environmental Degradation in North Korea
Unbearable Legacies: The Politics of Environmental Degradation in North Korea Peter Hayes Nearly 15 years ago, I wrote Enduring Legacies: Economic Dimensions of Restoring North Korea's Environment. This essay not only described a set of urgent environmental problems in North Korea, but also described its institutional and legal framework for environmental management. At the time, I had no idea that so many years would pass with no improvement in North Korea’s situation.

The year in review BEIRUT: Three months after the summer 2006 war with Israel, the Lebanese cannot swim in the sea, harvest crops, hike through the woods, drink water or breathe the air without worrying about the environmental impacts of the 34-day conflict.
Politics :: War added to Lebanon's many environmental problems
The environmental problems and politics of the United States have been shaped by the Cold War, from the kinds of hazards we face and the technologies we use to our budget priorities and controls on information. The political discourse framed the agendas and set the policies that strongly affected the kind of environmental politics that emerged here. There is no doubt that an end to the Cold War will mean a change in the military and ideological posture that this country has assumed for more than 40 years, a transformation with extraordinary political and policy consequences.
An Opportunity for Greener Politics : Environment: The end of the Cold War also ends the rationale for tolerating toxic pollution by the defense industry.
Japan claims its annual Antarctic whale hunt is its cultural heritage. Is it racist if we tell them to stop?

Letters: Our planet's appetite for destruction | Environment
Oxfam is right to highlight the long-term impacts of climate change, land grabbing and natural resource degradation on the price of staple foods, and the consequent rapid increase in the number of hungry people ( Harsh effects of global warming , 1 June). But while these trends require major policy and societal shifts to reverse, some of the short-term causes of hunger could be dealt with almost overnight. For example, much of the price volatility and inflation in food prices could be prevented by limiting the ability of banks and hedge funds to speculate on financial derivatives in food. Illustration: Gillian Blease The US is moving to rein in food speculation, and controls are also being debated in the EU – but our government is opposing such limits. In doing so, the UK risks becoming the chief global villain by putting the interests of a handful of super-rich traders over ensuring that people everywhere can fulfil a basic human need.On Sunday, the Prime Minister of England published an interesting article in The Observer . In the article, he advances the case that England is going to be the “greenest government ever” and that, in doing so, “it will drive by more than ten-fold the increase of renewable heat over the coming decade, radically reducing carbon emissions and creating thousands of jobs.” His primary point in the article is to say that there is a lot of money to be made in climate change initiatives and that it is not necessary to use the language of “threats and punishments,” which doesn't seem to be working anyway. It is a message that many in this country should take to heart. I thought EPA had come to this realization six months ago , but the inability to even have a discussion on cap-and-trade and, more recently, the election, has (as calculated) left EPA in a defensive mode.

Global food crisis: Counting the real cost of biofuels | Alex Evans | Global development
Corn is loaded into a truck in Valley Springs, South Dakota. In 2008, while biofuels accounted for just 1.5% of global liquid fuels supply that year, they represented nearly half the increase in major food crop consumption, mainly because of corn-based ethanol in the US. The rise in biofuels is a major contributor to the global food crisis. Photograph: Aaron Packard/Getty Images This year, 40% of America's corn crop will go into car engines rather than stomachs. Add the fact that the US is both the world's largest producer of corn and the largest exporter , and that 10 years ago only 7% of its crop went to ethanol production, and you start to see why enthusiasm for biofuels among oil importers has had such a marked impact on food prices.Culinary historians report that shark fin soup has been a Chinese delicacy since it first appeared on the Emperor’s table around the year 1400, during the Ming Dynasty.

Shark Fin Soup Facts
Wednesday, 13 January 2010 Laurel Beauprie/ Watershed Sentinel Stefan Klein/iStockphotos. It wouldn’t be news if I told you our planet has its environmental problems. We’re making some progress in controlling what we put into the air, put into our landfills and even put into our oceans. But we’re not paying enough attention to what we are taking out of our oceans – sharks – and they’re being killed at the rate of up to 73 million per year. That number refers to the number being killed only for their fins and almost entirely to make shark fin soup.Water
