• Soybean rust develops 'rolling' epidemics as spores travel north

    Although Midwestern soybean growers have yet to experience the brunt of soybean rust, growers in the southern United States are very familiar with the disease. Every year, the fungus slowly moves northward from its winter home in southern Florida and the Gulf Coast states, and eventually reaches Illinois soybean fields—often just before harvest.

  • Scientists Warn of Toxins in Texas Floodwaters from Superfund Sites

    Houston has been a hub of the petroleum and chemical industries for decades, leaving behind a landscape pocked with Superfund sites and other highly contaminated areas. Now, scientists are warning that these sites are likely leaking toxins into Tropical Storm Harvey’s floodwaters, exposing people in Harris County, where 30 percent of the land is now submerged, to dangerous contaminants, The Washington Post reported.

  • Robotic system monitors specific neurons

    Recording electrical signals from inside a neuron in the living brain can reveal a great deal of information about that neuron’s function and how it coordinates with other cells in the brain. However, performing this kind of recording is extremely difficult, so only a handful of neuroscience labs around the world do it.

    To make this technique more widely available, MIT engineers have now devised a way to automate the process, using a computer algorithm that analyzes microscope images and guides a robotic arm to the target cell.

  • Study negates concerns regarding radioactivity in migratory seafood

    When the Fukushima power plant released large quantities of radioactive materials into nearby coastal waters following Japan’s massive 2011 earthquake and tsunami, it raised concerns as to whether eating contaminated seafood might impair human health—not just locally but across the Pacific.

    A new study by an international research team shows that those concerns can now be laid to rest, at least for consumption of meat from migratory marine predators such as tuna, swordfish, and sharks.

  • Researchers Raise Public Health Concerns About Off-Road Vehicles and Inhalation of Asbestos

    Preventing injuries may not be the only reason children shouldn’t use off-road vehicles (ORVs).

    In a new study, public health scientists raise concerns that people who use ORVs in many regions of the country may face exposure to hazardous mineral fibers. These include naturally occurring asbestos and erionite – an asbestos-like material that occurs in sedimentary rocks of the western United States.

    Most of the deposits are located along the Appalachian Mountains and ranges in the West and Southwest, especially California.

  • New osteoporosis treatment uses traditional Chinese herb to prevent bone loss

    An herb widely used in traditional Chinese medicine might hold the key to a new osteoporosis therapy that could prevent bone loss without causing side effects.

    Using a compound derived from red sage, UBC researchers have found a way to selectively block an enzyme called Cathepsin K (CatK), which plays a major role in the breakdown of collagen in bones during osteoporosis. The findings were published in the Journal of Bone and Mineral Research.

  • Researchers discover new immunotherapy combination effective at killing cancer cells

    Immunotherapy is an emerging field in the global fight against cancer, even though scientists and clinicians have been working for decades to find ways to help the body’s immune system detect and attack cancerous cells. Doug Mahoney’s lab at the University of Calgary recently discovered an immunotherapy that uses existing cancer drugs in a whole new way.

  • Dispersants Improved Air Quality for Responders at Deepwater Horizon

    A study published Aug. 28, 2017, in the Proceedings of the National Academy of Sciencesadds a new dimension to the controversial decision to inject large amounts of chemical dispersants immediately above the crippled oil well at the seafloor during the Deepwater Horizon disaster in 2010. The dispersants likely reduced the amount of harmful gases in the air at the sea surface—diminishing health risks for emergency responders and allowing them to keep working to stop the uncontrolled spill and clean up the spilled oil sooner.

  • Study identifies methods for preventing overcrowding in emergency rooms

    No single solution exists for alleviating crowding in emergency rooms, but a new study identifies four key strategies that have reduced the problem.

    The study, published in the journal Annals of Emergency Medicine, concludes that engaged executive leadership can alleviate the problem when combined with a data-driven approach and coordination across the hospital from housekeepers to the CEO. Crowding in emergency rooms has been associated with decreased patient satisfaction and even death.

  • Technique Expedites Chemical Screening to Prioritize Toxicity Testing

    Researchers from North Carolina State University have developed a high-throughput technique that can determine if a chemical has the potential to activate key genes in seconds rather than the typical 24 hours or more. The technique can be used to prioritize chemicals for in-depth testing to determine their toxicity.
