Neonicotinoid pesticides tied to crashing bee populations, 2 studies find
A widely used farm pesticide first introduced in the 1990s has caused significant changes to bee colonies and removing it could be the key factor in restoring nature's army of pollinators, according to two studies released Thursday.
The scientists behind the studies in Europe called for regulators to consider banning the class of chemicals known as neonicotinoid insecticides. In the U.S., the Environmental Protection Agency told msnbc.com that the studies would be incorporated into a review that's currently under way.
A pesticide trade group questioned the data, saying the levels of pesticide used were unrealistically high, while the researchers said the levels used were typical of what bees would find on farms.
"Our study raises important issues regarding pesticide authorization procedures," stated Mikael Henry, co-author of a study on honey bees. "So far, they mostly require manufacturers to ensure that doses encountered on the field do not kill bees, but they basically ignore the consequences of doses that do not kill them but may cause behavioral difficulties."
"There is an urgent need to develop alternatives to the widespread use of neonicotinoid pesticides on flowering crops wherever possible," added the authors of the second study on bumble bees.
Last week, a coalition of environmental groups and beekeepers asked the EPA to suspend the use of the pesticide, which is widely used in flowering crops like corn, sunflower and cotton to combat insects.
The studies are the first to go outside the lab and into the fields, where the experts said they detected how the pesticide impacts bees as they collect pollen and pollinate flowers and crops.
Honey bee populations have been crashing around the world in recent years, and pesticides have been suspected, along with other potential factors such as parasites, disease and habitat loss, in what's known as Colony Collapse Disorder. In the U.S., some beekeepers in 2006 began reporting losses of 30-90 percent of their hives, according to the U.S. Department of Agriculture.
Combating Colony Collapse Disorder is hardly an esoteric exercise. The USDA notes that "bee pollination is responsible for $15 billion in added crop value, particularly for specialty crops such as almonds and other nuts, berries, fruits, and vegetables.
'Walmart of weed' opening store in Washington, D.C.
A company dubbed the "Walmart of Weed" is putting down roots in America's capital city, sprouting further debate on marijuana — medical or otherwise.
Just a few miles from the White House and federal buildings, a company that candidly caters to medical marijuana growers is opening up its first outlet on the East Coast. The opening of the weGrow store on Friday in Washington coincides with the first concrete step in implementing a city law allowing residents with certain medical conditions to purchase pot.
Like suppliers of picks and axes during the gold rush, weGrow sees itself providing the necessary tools to pioneers of a "green rush," which some project could reach nearly $9 billion within the next five years. Admittedly smaller than a big box store, weGrow is not unlike a typical retailer in mainstream America, with towering shelves of plant food and vitamins, ventilation and lighting systems. Along with garden products, it offers how-to classes, books and magazines on growing medical marijuana.
"The more that businesses start to push the envelope by showing that this is a legitimate industry, the further we're going to be able to go in changing people's minds," said weGrow founder Dhar Mann.
Although federal law outlaws the cultivation, sale or use of marijuana, 16 states and the District of Columbia have legalized its medical use to treat a wide range of issues from anxiety and back pain to HIV/AIDS and cancer-related ailments. Fourteen states also have some kind of marijuana decriminalization law, removing or lowering penalties for possession.
Nearly 7% of Americans, or 17.4 million people, said they used marijuana in 2010, up from 5.8%, or 14.4 million, in 2007, according to the Substance Abuse and Mental Health Services Administration. A Gallup poll last year found a record-high of 50% of Americans saying that marijuana should be made legal, and 70% support medical uses for pot.
Marijuana advocates also tout revenue benefits, as well as cost and efficiency savings for not prosecuting or jailing people for pot.

Bedrock of vaccination theory crumbles as science reveals antibodies not necessary to fight viruses
(NaturalNews) While the medical, pharmaceutical, and vaccine industries are busy pushing new vaccines for practically every condition under the sun, a new study published in the journal Immunity completely deconstructs the entire vaccination theory. It turns out that the body's natural immune systems, comprised of both innate and adaptive components, work together to ward off disease without the need for antibody-producing vaccines.
The theory behind vaccines is that they mimic infection by spurring B cells, one of the two major types of white blood cells in the immune system, to produce antibodies as part of the adaptive immune system. It is widely believed that these vaccine-induced antibodies, which are part of the more specific adaptive immune system, teach the immune system how to directly respond to an infection before the body becomes exposed to it.
But the new research highlights the fact that innate immunity plays a significant role in fighting infections, and is perhaps more important than adaptive immunity at preventing or fighting infections. In tests, adaptive immune system antibodies were shown unable to fight infection by themselves, which in essence debunks the theory that vaccine-induced antibodies serve any legitimate function in preventing or fighting off infection.
"Our findings contradict the current view that antibodies are absolutely required to survive infection with viruses like VSV (vesicular stomatitis virus), and establish an unexpected function for B cells as custodians of macrophages in antiviral immunity," said Dr. Uldrich H. von Andrian from Harvard Medical School. "It will be important to further dissect the role of antibodies and interferons in immunity against similar viruses that attack the nervous system, such as rabies, West Nile virus, and Encephalitis."
As explained by Dr. Russell Blaylock in a recent interview with Mike Adams, the Health Ranger, vaccines not only do not work as advertised, but they actually damage the body's innate immunity. Rather than teach the body how to respond to infections, vaccines actually inhibit the immune system's ability to produce TH2-type cytokines, and suppress cellular immunity, which is how the body protects itself against deadly viruses and bacteria.
So once again, the myth that vaccinations serve any sort of legitimate medical purpose has been deconstructed by breakthrough science. Regardless of whether or not the mainstream medical community wants to admit it, pro-vaccine ideology is increasingly finding itself in the dustheap of outmoded pseudoscience.

Yes, Deepwater Horizon Oil Did Enter the Food Chain
Along with the death of scores of marine animals and seabirds, one of the main concerns during the Deepwater Horizon oil spill was the impact on the food chain. A new study clarifies that impact: Hydrocarbons from the Macondo well trickled into the ocean food chain via its tiniest members, zooplankton.
Deepwater Horizon oil was found in zooplankton up to a month after the Macondo well was finally capped, the study found. Just as other oil spill studies have found, the impacts were patchy — some zooplankton far away from the wellhead showed evidence of contamination, while other plankton close by showed lower levels of exposure.
In any event, traces of oil in these tiny creatures shows they came into contact with the spilled oil, scientists say. Given their importance as a food source for a wide range of animals, this indicates compounds in the oil did work their way into the food chain — and still are.
The study was published in last month's issue of Geographical Research Letters.
Hundreds of Israelis march in Tel Aviv to protest war with Iran
Hundreds of Israelis marched in Tel Aviv on Saturday to protest against a possible Israeli strike on Iran's nuclear facilities. Get all the latest updates on Haaretz.com's Facebook page Anti-war protest - Hadar Cohen - 24.3.2012
The protest came amid a recent Facebook campaign linking Israeli and Iranian citizens in their opposition to war between the two nations. Campaign leaders, however, made it clear on their Facebook page that they had nothing to do with the Tel Aviv protest march.
Last week, graphic designers Ronny Edry and his wife, Michal Tamir, unknowingly began a Facebook phenomenon when they uploaded a poster depicting Edry and his daughter with the words, "Iranians, we will never bomb your country, we [heart] you."
That one image sparked a movement of sorts, with hundreds, if not thousands, of images sent from Israel, Iran, and elsewhere in the world, in support of exposing what participants consider to be the human side of the conflict between Iran and Israel.
