• For soybean growers, hidden cost of climate change exceeds $11 billion

    Even during a good year, soybean farmers nationwide are, in essence, taking a loss. This is because changes in weather patterns have been eating into their profits and taking quite a bite: $11 billion over the past twenty years. This massive loss has been hidden, in effect, by the impressive annual growth seen in soybean yields thanks to other factors. That growth, however, could have been 30 percent higher if weather variations resulting from climate change had not occurred, according to a new study.

  • WHO, worried about damage to West Africa’s economy, delayed declaring Ebola an emergency

    The World Health Organization(WHO) for two months delayed labeling the Ebola outbreak a global emergency for fear of damaging the economy of Guinea and neighboring countries, according to leaked documents and memos from the organization. Beginning in April 2014, WHO’s specialists, both in the field and at the organization’s headquarters in Geneva, were raising an alarm about the spreading epidemic — but it was not until June 2014 that WHO begun seriously to consider the scope of the outbreak, and it was not until August 2014 that WHO defined the Ebola outbreak as an epidemic and declared an international emergency.

  • Antibiotic resistance linked to poor governance, corruption

    Researchers examined antibiotic resistance in Europe from both a medical and a political-economic perspective, and found that antibiotic resistance is not related to a country’s wealth, but rather linked to poor governance and corruption. Countries with higher levels of corruption often had less rigorous and less transparent processes, with less effective controls over areas pertinent to antibiotic resistance. The researchers also found that resistance levels were higher when healthcare was performed by the private sector. This may be because clinicians in the private health system are subject to fewer controls when it comes to both the volumes and types of antibiotics used.

  • Chlorine used in sewage treatment may promote antibiotic resistance

    Chlorine, a disinfectant commonly used in most wastewater treatment plants, may be failing to completely eliminate pharmaceuticals from wastes. As a result, trace levels of these substances get discharged from the plants to the nation’s waterways. Now, scientists are reporting preliminary studies that show chlorine treatment may encourage the formation of new, unknown antibiotics that could also enter the environment, potentially contributing to the growing problem of antibiotic resistance.

  • California exploring water purification, imports, and conservation as water situation worsens

    California officials are calling on residents better to manage their water usage as the state enters its fourth consecutive year of drought. An average American uses 100 gallons of water each day, and reservoirs in California only have enough water to supply this level of consumption until the end of 2015. In 2014 alone, the state’s agriculture sector lost $2.2 billion in revenue as a result of the drought. State officials acknowledge that a heavy rainfall alone will not be sufficient to restore the groundwater the state needs, so water districts are investing in water recycling plants and exploring strategies ranging from importing water to encouraging greater conservation.

  • Wireless implantable medical devices vulnerable to hacking

    With rapidly advancing medical technologies, more and more Americans are fitted with wireless implantable medical devices (IMDs) such as cardiac pacemakers, defibrillators, cochlear implants, neuro-stimulators, and insulin pumps. This is leading to growing concerns over the vulnerability of such devices to hacking.

  • Long-held theory on how bacteria causes bubonic plague overturned

    The current outbreak of the plague in Madagascar shines a light on the need for new approaches to treat the ancient pathogen. A new UNC study unexpectedly unravels a long-held theory on how a fleabite leads to infection. For decades, scientists have thought the bacteria that cause the bubonic plague hijack host cells at the site of a fleabite and are then taken to the lymph nodes, where the bacteria multiply and trigger severe disease. Researchers discovered, however, that this accepted theory is off base. The bacteria do not use host cells; they traffic to lymph nodes on their own and not in great numbers.

  • Escape of deadly bacteria at Louisiana bio-research facility raises concerns

    Weeks after federal and state officials launched an investigation into how the burkholderia pseudomallei bacteria which causes life-threatening disease Melioidosis, escaped a laboratory at the Tulane National Primate Research Center in Louisiana, another investigation is now looking into how a veterinary clinic worker might have been exposed to the bacteria.Tulane was conducting vaccine research on the bacteria in a laboratory that requires a biosafety level 3 rating — - the second highest security level.

  • NBAF-focused research already underway at K-State U, ahead of level-4 biolab opening

    Although the remaining funding for the National Bio and Agro-defense Facility, or NBAF, was recently finalized, work on the federal livestock research facility has continued to move forward in recent years — including Kansas State University conducting research which will help jump-start future operations at NBAF. NBAF will be DHS’s premier foreign animal disease research lab. It will research high-consequence livestock diseases that threaten animal and human health. The $1.25 billion lab will be on the northeast edge of K-State Manhattan, Kansas campus. NBAF is anticipated to begin operations in 2022 or 2023. Construction of the facility’s central utility plant is more than 90 percent complete.

  • Protecting crops from radiation-contaminated soil

    Almost four years after the accident at the Fukushima Daiichi Nuclear Power Plant in Japan, farmland remains contaminated with higher-than-natural levels of radiocesium in some regions of Japan, with cesium-134 and cesium-137 being the most troublesome because of the slow rate at which they decay. In a just-published study, scientists have identified a chemical compound that prevents plants from taking up cesium, thus protecting them — and us — from its harmful effects.

  • When parents hesitate about vaccines, what should health-care providers say?

    By Kristin S. Hendrix

    In recent years, the United States has witnessed multiple outbreaks of vaccine-preventable illnesses, including pertussis (whooping cough) and measles. In the same time frame, vaccine refusal rates have gone up, and an increasing number of parents are requesting modified vaccine schedules that differ from the one recommended by the American Academy of Pediatrics (AAP). Although research overwhelmingly supports the safety and effectiveness of vaccines and indicates that the risk of negative side effects from childhood vaccines is extremely small, many parents still have concerns about vaccine safety. More research is needed to determine which interventions and ways of communicating information about vaccination are most effective at reducing parents’ vaccine hesitancy and refusal. What is clear from existing research is that respectful, tailored communications and recommendations to immunize coming directly from the health-care provider are associated with increased vaccination uptake.

  • Aluminum poses a threat to food security

    One third of the world’s food-producing land has been lost in the past forty years as a result of soil degradation, putting global food security at risk. Researchers have discovered how aluminum, a toxic result of soil acidification, acts to reduce plant growth. The researchers discovered that aluminum in soils could reduce the growth of roots within five to thirty minutes of exposure.

  • Agriculture groups say bill would disrupt farming operations, decrease food production

    The Legal Workforce Act(LWA — H.R. 1147), introduced by U.S. Representative Lamar Smith (R-Texas) and approved this week by the House Judiciary Committee, could disrupt farming operations if it passes Congress. LWA requires employers in the United States, within three years, to use E-Verifyto verify whether employees are legally allowed to work in the country. Ag industry groups say that passing LWA without some sort of immigration reform for agricultural workers could lead to a $30 billion to $60 billion decrease in food production. The ag industry also notes that each of the two million hired farm employees supports two to three fulltime American jobs in the food processing, transportation, farm equipment, marketing, retail, and other sectors.

  • DHS termination of bio-detection contract questioned

    In February 2014, six months before Silicon Valley startup NVS delivered the first prototypes of its polymerase chain reaction (PCR) pathogen detector to DHS, the department sent NVS’s chief executive Hans Fuernkranz a notice terminating the project. According to a 26 November 2014 draft audit report by DHS’s inspector general’s office, the decision was improperly made by a single agency official without supporting evidence and “against S&T [DHS Science & Technology Directorate] subject matter expert advice.”The official who made the decision to cancel the project had expressed concerns about the cost associated with the NVS contract, and said the contract was terminated because existing technologies could better meet the agency’s needs for confronting bio-threats. The auditors say, however, that they “did not identify evidence to substantiate any of the concerns.”

  • Warming temperatures cause of recent California droughts

    California has experienced more frequent drought years in the last two decades than it has in the past several centuries. That observed uptick is primarily the result of rising temperatures in the region, which have climbed to record highs as a result of climate change, Stanford scientists say. Researchers have examined the role that temperature has played in California droughts over the past 120 years. They also examined the effect that human emissions of carbon dioxide and other greenhouse gases are having on temperature and precipitation, focusing on the influence of global warming upon California’s past, present, and future drought risk. The team found that the worst droughts in California have historically occurred when conditions were both dry and warm, and that global warming is increasing the probability that dry and warm years will coincide. The findings suggest that California could be entering an era when nearly every year that has low precipitation also has temperatures similar to or higher than 2013-14, when the statewide average annual temperature was the warmest on record.
