Study: More pesticides used on 'superweeds'
By Reuters U.S. farmers are using more hazardous pesticides to fight weeds and insects due largely to heavy adoption of genetically modified crop technologies that are sparking a rise of "superweeds" and hard-to-kill insects, according to a newly released study. Genetically engineered crops have led to a 404 million pounds increase in overall pesticide use by from the time they were introduced in 1996 through 2011, according to the report by Charles Benbrook, a research professor at the Center for Sustaining Agriculture and Natural Resources at Washington State University. Of that total, herbicide use increased over the 16-year period by 527 million pounds while insecticide use decreased by 123 million pounds. Benbrook's paper -- published in the peer-reviewed journal Environmental Sciences Europe over the weekend and announced on Monday -- undermines the value of both herbicide-tolerant crops and insect-protected crops, which were aimed at making it easier for farmers to kill weeds in their fields and protect crops from harmful pests, said Benbrook. 'Major problem' The crops were a hit with farmers who found they could easily kill weed populations without damaging their crops. But in recent years, more than two dozen weed species have become resistant to Roundup's chief ingredient glyphosate, causing farmers to use increasing amounts both of glyphosate and other weed-killing chemicals to try to control the so-called "superweeds." "Resistant weeds have become a major problem for many farmers reliant on GE crops, and are now driving up the volume of herbicide needed each year by about 25 percent," Benbrook said. Could genetically modified seeds be a drought solution? Monsanto officials had no immediate comment. "We're looking at this. Our experts haven't been able to access the supporting data as yet," said Monsanto spokesman Thomas Helscher. Benbrook said the annual increase in the herbicides required to deal with tougher-to-control weeds on cropland planted to genetically modified crops has grown from 1.5 million pounds in 1999 to about 90 million pounds in 2011. Similarly, the introduction of genetically modified "Bt" corn and cotton crops engineered to be toxic to certain insects is triggering the rise of insects resistant to the crop toxin, according to Benbrook. 'Best year ever' for some farmers outside drought region Insecticide use did drop substantially - 28 percent from 1996 to 2011 - but is now on the rise, he said. "The relatively recent emergence and spread of insect populations resistant to the Bt toxins expressed in Bt corn and cotton has started to increase insecticide use, and will continue to do so," he said. Herbicide-tolerant and Bt-transgenic crops now dominate U.S. agriculture, accounting for about one in every two acres of harvested cropland, and around 95 percent of soybean and cotton acres, and over 85 percent of corn acres. "Things are getting worse, fast," said Benbrook in an interview. "In order to deal with rapidly spreading resistant weeds, farmers are being forced to expand use of older, higher-risk herbicides. To stop corn and cotton insects from developing resistance to Bt, farmers planting Bt crops are being asked to spray the insecticides that Bt corn and cotton were designed to displace."

Gold, gems stolen in $2 million mining museum heist
John Palmer / California State Parks via AP Authorities say thieves made off with an estimated $2 million in gold and precious gems during the armed robbery at the California State Mining and Mineral Museum, seen in this 2009 photo. By NBC News staff and wire reports LOS ANGELES -- Robbers wearing masks and goggles broke into a mining museum in California in broad daylight and stole gold and gems valued at up to $2 million, authorities said. Although no-one has been identified in connection with the burglary, California investigators are searching for at least two suspects. The masked men broke into the California State Mining and Mineral Museum in Mariposa, California, on Friday afternoon with pickaxes and forced employees into one end of the building, the Los Angeles Times reported, citing a state parks spokesman. Read the story on NBC station KCRA But the thieves didn't get away with the biggest prize of all -- the nearly 14-pound Fricot Nugget, a giant crystalline gold mass unearthed in the California Gold Rush era. The robbers triggered an alarm as they tried to break into the iron safe where it was held. According to the museum's website, the Fricot Nugget was discovered in the American River in Northern California in 1864 and is the largest intact mass of crystalline gold remaining from the Gold Rush era. The California State Mining and Mineral Museum is described on its website as offering visitors the chance to explore the variety of the state's mineral wealth and view "breathtaking gems and minerals from around the world." The California department of parks and recreation issued a statement on Monday saying the museum would be closed "until further notice while repairs are completed." The statement added that the museum is taking an inventory of the stolen items this week, which will allow it to confirm what was taken and exactly how much the items were worth. The Los Angeles Times reported that the museum had moved its treasures to an undisclosed location in the meantime. The burglary was the second theft of this year involving rare, valuable minerals in Northern California. Chunks of gold were stolen from the Siskiyou County courthouse in February. No suspects have been identified and authorities are investigating whether there is a connection between the two incidents. NBC News staff and Reuters contributed to this report.

Group: Police rape woman, charge her
(CNN) -- Outraged Tunisians will take to the streets Tuesday to protest the treatment of a woman who was allegedly raped by police officers -- and then charged with public indecency when she filed a complaint against them. "At best, charging the victim of a rape by police officers instead of protecting her from intimidation and stigma highlights the deep flaws on Tunisian law and criminal justice system," said Hassiba Hadj Sahraoui, deputy Middle East and North Africa program director at Amnesty International. "At worst, it is an insidious attempt to discredit a rape victim and protect those she accused of raping her." The case began September 3 when three police officers approached the woman and her fiance while they were in their car in the capital Tunis, the woman's lawyer told Amnesty. Two of the officers then raped the woman inside the car, while the third took her fiance to a nearby ATM to extort money from him, the woman claimed. It was only after she filed a complaint against the officers -- and they were charged with rape and extortion -- that the officers said they found the couple in an "immoral position" in the car. Authorities have not specified what they meant by "immoral position," but the claim was later repeated by the country's interior ministry, Amnesty said. The couple was charged with "intentional indecent behavior," which could yield up to six months in prison. Both have denied the charges, and expect to appear at a court hearing Wednesday. The decision to charge the woman incensed human rights groups like the Tunisian League of Human Rights and the Tunisian Association of Democratic Women, who have called for protests outside the Tunis courthouse. "We fear that the treatment afforded to the young woman will deter other victims of sexual abuse from coming forward and as they may fear being treated as the accused rather than the victim," Amnesty's Sahraoui said. Tunisia is the birthplace of the Arab Spring, a series of revolutions that swept across northern African and the Middle East. On December 17, 2010, Mohamed Bouazizi, a young Tunisian street vendor, set himself on fire in protest, sparking the movement that still ripples through the region. Tunisia's revolution ousted President Zine el Abidine Ben Ali and brought about a new government and political system, including a new draft constitution. But challenges remain. Last month, the government rejected a U.N. Human Rights Council's recommendation to abolish discrimination against women in areas such as inheritance and child custody. In addition, Tunisian authorities have charged journalists and human rights activists in recent months with "public immorality" and "public disorder" to restrict freedom of expression, rights group say. |
