• Arsenic contamination in food and water supplies

    After virtually eliminating arsenic as a useful tool for homicide, science now faces challenges in doing the same for natural sources of this fabled old “inheritance powder” that contaminates water supplies and food, threatening more than thirty-five million people worldwide.

  • Concerns grow over repeated safety failures at U.S. BioLabs

    According to a report that was released by the Government Accountability Office (GAO) late last month, the United States is at a high risk for accidents at laboratories which conduct research on potential bioterror germs such as anthrax because federal officials have failed to develop national standards for lab design, construction, and operation.

  • Farm states pass bills to protect farms from activists, whistle-blowers

    In an effort to stop animal rights activists from recording acts of animal cruelty on farms, lawmakers in twelve states have proposed or enacted bills which would make it illegal secretly to record livestock farms or apply for a job at a farm without disclosing ties to animal right organizations.

  • L.A County to turn rain water into drinking water

    Residents of Los Angeles County know that on the rare occasion that it rains, staying away from the beach is a good idea. Runoff from rain typically brings heavy metals, pesticides, cigarette butts, animal waste, and other pollutants  into the streams and rivers which go into the Pacific Ocean. Now, local officials are getting together to find a solution to the water pollution and water scarcity, with an ambitious plan to make the runoff water drinkable.

  • Finding the right tools to respond to suspicious powder incidents

    HazMat teams across the United States respond to hundreds of white powder calls each year in large cities where quick decision-making is critical. DHS makes it easier to buy the right technology for bio-threat incidents.

  • New device will quickly detect botulinum, ricin, other biothreat agents

    Researchers are developing a medical instrument which will be able quickly to detect a suite of biothreat agents, including anthrax, ricin, botulinum, shiga, and SEB toxin. The device, once developed, approved by the Food and Drug Administration (FDA), and commercialized, would most likely be used in emergency rooms in the event of a bioterrorism incident.

  • China catches 12 times more fish beyond its waters than it reports

    Chinese fishing boats catch about $11.5 billion worth of fish from beyond their country’s own waters each year — and most of it goes unreported. Researchers estimate Chinese foreign fishing at 4.6 million tons per year, taken from the waters of at least ninety countries — including 3.1 million tons from African waters, mainly West Africa.

  • Same-day water test keeps beaches open, swimmers’ health protected

    With warm summer days at the beach on the minds of millions of winter-weary people, scientists are reporting that use of a new water quality test this year could prevent unnecessary beach closures, while better protecting the health of swimmers.

  • Nanobiotechnology kills listeria, other food-borne pathogens, dead

    Researchers, using nature as their inspiration, successfully attached cell lytic enzymes to food-safe silica nanoparticles, and created a coating with the demonstrated ability selectively to kill listeria — a dangerous foodborne bacteria that causes an estimated 500 deaths every year in the United States.  The coating kills listeria on contact, even at high concentrations, within a few minutes without affecting other bacteria.

  • Genetically engineered multi-toxin crops make insects insecticide-resistant

    The popular new strategy of planting genetically engineered crops that make two or more toxins to fend off insect pests rests on assumptions that do not always apply, researchers have discovered. Their study helps explain why one major pest is evolving resistance much faster than predicted and offers ideas for more sustainable pest control.

  • New foot-and-mouth vaccine shows promise

    The 2001 foot and mouth outbreak in Britain was devastating and cost the economy billions of pounds in control measures and compensation. One recommendation in a Royal Society report following the epidemic recommended the development of new approaches to control the virus. Scientists have used a new method to produce a vaccine which does not rely on inactivating the live, infectious virus which causes the disease — and is therefore much safer to produce.

  • More than 10,000 pesticides approved by EPA without rigorous review

    Congress allowed the Environmental Protection Agency (EPA) to use what is called “conditional registration” to approve pesticides deemed especially beneficial for food production – even before all the toxicity tests have been completed. Congress intended conditional registration to be used only sparingly, but the EPS has been using the loophole in a wholesale fashion to approve 65 percent – or more than 10,000 – of the 16,000 pesticides submitted to it for approval. The EPA cannot easily track the history of conditionally approved pesticides to determine whether required toxicity data was submitted, whether that caused a dangerous use of a pesticide to be cancelled, or whether the uses or restrictions should be modified based in such data.

  • Focusing on climate’s impact on fisheries leads to misguided conclusions

    In the early 1940s, California fishermen hauled in a historic bounty of sardine at a time that set the backdrop for John Steinbeck’s novel Cannery Row. By the end of the decade, however, the nets came up empty and the fishery collapsed. Where did they all go? A new study argues that the problem in seeking answers to this – and similar – questions lies in the fact that researchers typically try to find the answers by focusing on one factor at a time. What is the impact of climate on sardines? What is the effect of overfishing on sardines? Focusing on single variables in isolation can lead to misguided conclusions, the authors of the study say. The authors argue that climate, human actions, and ecosystem fluctuations combine to influence sardine and other species populations, and therefore such factors should not be evaluated independently.

  • Predicting disease outbreaks to protect soldiers -- and civilians

    Researchers from Johns Hopkins University and the Pentagon develop a new method to predict dengue fever outbreaks several weeks before they occur. The method extracts relationships between clinical, meteorological, climatic, and socio-political data. It can be used in any geographical region and extended to other environmentally influenced infections affecting public health and military forces worldwide. DoD is currently evaluating the method for use in mitigating the effects of infectious disease in various operational settings.

  • First botulism antitoxin approved for neutralizing all seven known botulinum serotypes

    The U.S. Food and Drug Administration on Friday announced that it has approved Botulism Antitoxin Heptavalent to treat patients showing signs of botulism following documented or suspected exposure to botulinum neurotoxin. The product, which is derived from horse plasma, will be stored in Strategic National Stockpile for emergency preparedness and responses.
