• World-wide alert for Yosemite hantavirus risk

    U.S. health officials have alerted thirty-none countries that their citizens, who, as tourists,  have stayed in Yosemite National Park tent cabins this summer, may have been exposed to a deadly mouse-borne hantavirus

  • Heat waves move toward California coasts, become more humid, imperiling health

    Scientists detected a trend toward more humid heat waves which are expressed very strongly in elevated nighttime temperatures, a trend consistent with climate change projections; moreover, relative to local warming, the mid-summer heat waves are getting stronger in generally cooler coastal areas; this carries strong public health implications for the twenty-one million Californians living near the ocean whose everyday lives are acclimated to moderate temperatures

  • Smart agriculture will increase global food production, reduce environmental impact

    Global demand for food is expected to double by 2050 due to population growth and increased standards of living; a new study, based on analysis of agricultural data gathered from around the world, offers hope that with more strategic use of fertilizer and water, we could not only dramatically boost global crop yield, but also reduce the adverse environmental impact of agriculture

  • Near-instantaneous DNA analysis

    Polymerase chain reaction (PCR) is an indispensible technique allowing researchers and clinicians to produce millions of copies from a single piece of DNA or RNA for use in genome sequencing, gene analysis, inheritable disease diagnosis, paternity testing, forensic identification, and the detection of infectious diseases; PCR for point-of-care, emergency-response, or widespread monitoring applications needs to be very fast — on the order of a few minutes; this has now been achieved

  • Antibiotic residues in sausage meat may promote pathogen survival

    Antibiotic residues in uncured pepperoni or salami meat are potent enough to weaken helpful bacteria that processors add to acidify the sausage to make it safe for consumption; sausage manufacturers commonly inoculate sausage meat with lactic-acid-producing bacteria; by killing the bacteria that produce lactic acid, antibiotic residues can allow pathogenic bacteria to proliferate

  • Cooling coal emissions would clean air, lower health, climate-change costs

    In the United States there are about 1,400 electric-generating unit powered by coal, operated at about 600 power plants; the estimated health costs of burning coal in the United States are in the range of $150 billion to $380 billion, including 18,000-46,000 premature deaths, 540,000 asthma attacks, 13,000 emergency room visits, and two million missed work or school days each year; scientists estimate that implementing large-scale cryogenic systems into coal-fired plants would reduce overall costs to society by 38 percent through the sharp reduction of associated health-care and climate-change costs

  • DHS using Boston subway system to test new sensors for biological agents

    Bioterrorism is nothing new, and although medicines have made the world a safer place against a myriad of old scourges both natural and manmade, it still remains all too easy today to uncork a dangerous cloud of germs; DHS’s Science and Technology Directorate (DHS S&T) has scheduled a series of tests in the Boston subways to measure the real-world performance of new sensors recently developed to detect biological agents

  • U.S. risks losing out to Asia in medical research

    Medical research saves lives, suffering, and dollars — while also creating jobs and economic activity; the United States has long led the world, with hundreds of thousands of jobs and marketable discoveries generated by government research funding every year; this is now changing: strong, sustained growth in research spending in Asian nations contrasts with U.S. cuts and short-term approach, and a brain drain could result

  • No-till could help stabilize crop yields despite climate change

    Reducing tillage for some Central Great Plains crops could help conserve water and reduce losses caused by climate change, according to studies at the U.S. Department of Agriculture

  • Napa Valley hospital employees fearful of new, wearable security system

    Employees at a Napa Valley, California hospital are required to carry an alarm device on a lanyard around their necks; the alarm device is about the size of a smart phone and can send and receive signals during an emergency; after incidents in which psychiatric patients tried to choke employees by grabbing and twisting the lanyards, employees want other options for carrying the alarm device

  • CDC says West Nile virus outbreak worst in years

    The Center for Disease Control(CDC) says that last year’s mild winter and a wet spring have contributed to the worst West Nile virusoutbreak since its initial detection in 1999; according to the CDC, as of 14 August, at least 693 cases that have been reported across the United States, including twenty-eight deaths

  • China’s food production characterized by corruption, health-threatening practices

    A report on Chinese TV showed rotten peaches spiked with sodium metabisulfite to make the fruit look fresh, seasoned in bleaching agents and additives harmful to the human liver and kidneys, and pickled in outdoor pools surrounded by garbage; the peaches are then packed in dirty bags which were previously used to hold animal feed, and shipped off to big brand stores; trouble is, this story is typical of, rather than an exception to, food production practices in China 

  • Simple new test combats counterfeit drugs in developing countries

    The World Health Organization (WHO) estimates that at least 10 percent of the drug supply in developing countries consists of counterfeit medicines, causing thousands of deaths every year; many of the deaths occur among people who unknowingly take counterfeit antibiotics and anti-malaria medicines that do not contain the active ingredient to combat those diseases; in addition to lacking the active ingredient, counterfeit medicines may harm people by containing ingredients that are potentially toxic

  • World could be in for higher food prices

    This has been one of the driest summers in American history, but the weather is not only affecting the United States; weak monsoons in India and other weather issues across the globe are affecting crops and could lead to higher food prices in 2013

  • Bacteria in tap water traced to the water treatment process

    Most of the bacteria that remain in drinking water when it gets to the tap can be traced to filters used in the water treatment process, rather than to the aquifers or rivers where they originated; the findings could open the door to more sustainable water treatment processes that use fewer chemicals and, as a result, produce lower levels of byproducts that may pose health risks; eventually, the work could enable engineers to control the types of microbes in drinking water to improve human health
