• Handheld sensor sniffs out fish fraud

    It is estimated that up to 30 percent of the seafood entering the U.S. is fraudulently mislabeled, bilking U.S. fishermen, the U.S. seafood industry, and American consumers for an estimated $20-25 billion annually. Passing off other fish as grouper is one of the rackets this sensor aims to stop. Fighting seafood labeling fraud using rapid, on-site screening may benefit consumer wallets and U.S. seafood industry. Scientists at the University of South Florida’s College of Marine Science have developed a handheld sensor capable of debunking fraudulent seafood species claims, helping to ensure that consumers are getting what they pay for.

  • Color-changing film detects chemical weapons

    In today’s world, in which the threat of terrorism looms, there is an urgent need for fast, reliable tools to detect the release of deadly chemical warfare agents (CWAs). Scientists are reporting progress toward thin-film materials that could rapidly change colors in the presence of CWAs — an advance that could help save lives and hold aggressors accountable.

  • Lawmakers seek to create single food safety agency to improve oversight

    Lawmakers are seeking to pass a bill which would a single food safety agency to replace the current multi-agency system, which critics say is “hopelessly fragmented and outdated.” Senator Richard Durbin (D-Illinois) and Representative Rosa DeLauro (D-Connecticut) have proposed the 2015 Safe Food Act, which would replace the current food safety oversight system – which consists of fifteen different agencies — with a single organization.

  • New biosurveillance Web site offers comprehensive information on outbreaks, responses

    A new online resource is providing a centralized portal for all news, information, resources, and research related to biosurveillance at the laboratory. Los Alamos Lab science team gathers a virtual biological toolkit for international disease outbreak response.

  • Ebola epidemic ebbing: WHO

    The World Health Organization(WHO) has reported fewer than 100 new cases of Ebola in West Africa in the last week, which means the outbreak could soon reach its end. Some of the resources allocated to building treatment centers for thousands of sick people are now being diverted to contact-tracing efforts. “Efforts have moved from rapidly building infrastructure to ensuring that capacity for case finding, case management, safe burials and community engagement is used as effectively as possible,” read the WHO’s latest situation report.

  • Chinese ownership of a methanol plant worries Louisiana parish residents

    Roughly 150 petrochemical companies and seventeen refineries operate in a zone between Baton Rouge and New Orleans, an area locals call “Cancer Alley” due to the health concerns that have arisen during the past few decades of industrialization. Residents of St. James Parish have voiced their opposition to a proposed methanol plant in the parish. The plant will be operated by Yuhuang Chemical Inc., a subsidiary of Chinese natural gas giant Shandong Yuhuang. Recently, Shandong Yuhuang, parent company of the proposed plant in St. James, has received bad press in China for reportedly neglecting environmental laws, including releasing toxic emissions in the city of Heze, which environmentalists have connected to rising cancer rates and contaminated water.

  • Genetic safety switches curb bioterror risk

    The potential threat of bioterrorism using man-made biological organisms could be curbed, thanks to a new method. Synthetic biologists — who can design and modify the DNA of living organisms to give them novel, useful functions — have devised a way of containing their products to help ensure that they work only as intended.

  • Ebola outbreak: where we are now and what happens next

    Ever since its discovery, it has been appreciated that Ebola poses a serious risk to global public health. Infectious diseases represent a global threat, not just to those within the country or region of emergence. With the current increase in the movement of people (rural to urban, within countries and across borders), this risk will inevitably increase. While the current priority should be to contain the present outbreak, there is a great need to plan for prevention of future events. The development of an international response group tasked with immediate assessment of and initial response to emerging pathogens is needed, backed by sufficient international political will, clinical expertise, and funding. This needs to be agile and responsive, with clear chains of command, and able to engage early.

  • A computer program would track food, ingredients in packaged food, imported into U.S.

    Scientists at University of Minnesota’s National Center for Food Protection and Defense(NCFPD) are developing a computer program called CRISTAL, which could allow the government and private sector to map the supply chain of every product imported into the United States, from mobile phones to car seats to the ingredients in packaged foods. The USDA already monitors some aspects of the nation’s food safety, but DHS is particularly interested in CRISTAL because of increasing terror threats to the nation’s food supply.

  • Challenges for sustainability as many renewable resources max out

    The days of assuming natural resources can be swapped to solve shortages — corn for oil, soy for beef — may be over. An international group of scientists demonstrate that many key resources have peaked in productivity, pointing to the sobering conclusion that “renewable” is not synonymous with “unlimited.” The researchers examined renewable resources, such as corn, rice, wheat, or soy, which represent around 45 percent of the global calorie intake. They also reviewed fish, meat, milk, and eggs. The annual growth rate of eighteen of these renewable resources — for example, increase in meat production or fish catch — peaked around 2006.

  • Speeding up Ebola drug production

    Researchers at the University of California, Davis, will explore ways to speed production of the Ebola drug Zmapp with a $200,000 rapid-response grant from the National Science Foundation. Zmapp is a cocktail of antibodies produced in and extracted from whole tobacco plants. The UC Davis team, including plant scientists, molecular biologists and chemical engineers, will attempt to produce the antibodies from plant cells grown in bioreactors instead of in whole plants.

  • Medical devices, not only medical records, are vulnerable to hackers

    Health organizations have spent millions of dollars to protect hospital computer systems and software from malware, but hospitals today are increasingly equipped with many medical devices linked to Wi-Fi, making the devices a portal to hospital room operations. Infusion pumps deliver measured doses of nutrients or medications such as insulin or other hormones, antibiotics, chemotherapy drugs, and pain relievers into a patient’s body. Although it has yet to happen, it is quite possible for a hacker to infiltrate an active infusion pump on a hospital’s Wi-Fi and change the dosage. Hackers can also use the pump’s network access to inject malware in the hospital’s network systems, giving them entry to patients’ medical records. The records can then be sold to identity thieves.

  • High security Australian laboratory advancing Ebola research

    With the Ebola epidemic still a threat, many in the international disease research community are searching for a cure. One such laboratory is a high-security facility in Geelong, Australia. It focuses exclusively on Ebola research and testing, particularly the Zaire strain of the virus, which has ravaged Guinea, Liberia, and Sierra Leone.

  • New technology quickly traces source of tainted food

    Foodborne illnesses kill roughly 3,000 Americans each year and about 1 in 6 are sickened, according to the Centers for Disease Control and Prevention. Yet most contaminated foods are never traced back to their source. This is because existing methods to track tainted food following its supply chain from table to farm are highly inefficient, jeopardizing the health of millions and costing the food industry billions. A typical process to trace food includes interviewing consumers and suppliers and examining every detail of the supply chain, a tedious method that takes weeks at best to complete. Researchers have now developed a cost-effective and highly efficient method to accurately trace contaminated food back to its source.

  • Agroterrorism is a major threat to America: Experts

    The economic effects of a successful attack on the U.S. food supply would be devastating, as agriculture accounts for roughly 13 percent of the country’s gross annual domestic product. An introduction of deadly pathogens into U.S. livestock, poultry, or crops would not only result in a disease outbreak, but would disrupt the global food industry and drive up food prices. Agroterrorism is not limited to the intentional introduction of harmful pathogens into U.S. farms and livestock. Terrorists can also cyberattack industrial agriculture systems responsible for operating feeding machines, maintaining milk temperatures, and processing foods.
