• Freshwater loss compounds climate change’s detrimental effects on agriculture

    A warmer world is expected to have severe consequences for global agriculture and food supply, reducing yields of major crops even as population and demand increases.Agricultural models estimate that given the present trajectory of greenhouse gas emissions, climate change will directly reduce food production from maize, soybeans, wheat, and rice by as much as 43 percent by the end of the twenty-first century. Now, a new analysis combining climate, agricultural, and hydrological models finds that shortages of freshwater used for irrigation could double the detrimental effects of climate change on agriculturedue to the reversion of twenty to sixty million hectares of currently irrigated fields back to rain-fed crops.

  • Uranium found to be mobile in a natural wetland

    Because they are known to mop up pollutants, artificial wetlands are considered to be an efficient strategy to contain waterborne uranium. Studying a natural wetland near a former uranium-mining site in the French region of Limousin, however, researchers have found that under certain circumstances, uranium can be partly remobilized into the surrounding water. The researchers show how it becomes mobile again by binding to tiny metallic and organic compounds with a little help from ambient bacteria.

  • Superbugs discovered to be breeding in sewage plants

    Rice University study finds that two wastewater treatment plants in China fail to kill antibiotic-resistant bacteria. The bacteria were not only escaping purification but also breeding and spreading their dangerous cargo.

  • Upper Rio Grande to experience growing gap between water supply and demand

    Increasing temperatures and changes in the timing of snowmelt runoff could impact the amount of water available on the upper Rio Grande in the future, says a news study. Temperatures will increase four to six degrees Fahrenheit by the end of the twenty-first century, according to the climate modeling used in the study. Although the modeling projects that total annual average precipitation in the basin will not change considerably, we are likely to see a decreasing snowpack, an earlier and smaller spring snowmelt runoff and an increase in the frequency, intensity and duration of both droughts and floods.

  • Survey of deep-sea chemical munitions dump off California finds no chemical weapons

    Since the Second World War, U.S. nautical charts have shown seven “chemical munitions dumping areas” along the Pacific Coast between San Francisco and the Mexican border. Little or no information, however, is available about the amount, location, or nature of the materials that were dumped at most of these sites. Researchers from the Monterey Bay Aquarium Research Institute (MBARI) conducted a detailed survey of one supposed deep‐water dump site off Southern California, and found that it contained no chemical munitions. The researchers conclude that not all sites marked as chemical munitions dumps may actually have been used for this purpose.

  • James Bond drank too much to perform at the level depicted in books, movies

    A detailed examination of James Bond’s books shows that Bond’s weekly alcohol intake is over four times the recommended limit for an adult male, putting him at high risk of several alcohol related diseases, such as alcoholic liver disease, cirrhosis, impotence, and alcohol-induced tremor, and an early death. The medical team concluded that it would not be realistic to expect Bond to have the capacity to perform (in all aspects of life) at his high level of alcohol intake.

  • India-Pakistan nuclear war would lead to world-wide famine: study

    An India-Pakistan nuclear war may see the use of about 100 Hiroshima-size bombs – about half of India and Pakistan’s nuclear arsenals. A new study says that a nuclear exchange on such a scale would “probably cause the end (of) modern industrial civilization as we know it” by subjecting about two billion people to the risk of starvation, and causing massive economic and social disruptions far away from the theater of war. Among the consequences of a nuclear exchange: Chinese winter wheat production could decline by 50 percent during the first year and by more than 30 percent over ten years; there would be a 21 percent decline in Chinese middle-season rice production during the first four years and an average 10 percent decline in the following six years; corn and soybean production in the United States would decline by 10 percent on average for ten years.

  • Air transportation data helps identify, predict pandemics

    Computational model demonstrates how disease spreads in a highly connected world. The computational work has led to a new mathematical theory for understanding the global spread of epidemics. The resulting insights could not only help identify an outbreak’s origin but could also significantly improve the ability to forecast the global pathways through which a disease might spread.

  • Food security and self-provision of major cities

    Wealthy capital cities vary greatly in their dependence on the global food market. The Australian capital Canberra produces the majority of its most common food in its regional hinterland, while Tokyo primarily ensures its food security through import. The Copenhagen hinterland produces less than half of the consumption of the most common foods. For the first time, researchers have mapped the food systems of capital cities, an essential insight for future food security if population growth, climate change, and political instability will affect the open market.

  • U.K. tightens animal disease surveillance

    The U.K. Animal Health and Veterinary Laboratories Agency(AHVLA) has introduced a new surveillance system to detect new and re-emerging animal disease threats in England and Wales. The new system is expected to improve the geographical and species-specific coverage of disease.The new system will rely more on private sector laboratories for gathering surveillance intelligence and less on government laboratories.

  • New weapon in the war on superbugs

    In the arms race between bacteria and modern medicine, bacteria have gained an edge. In recent decades, bacterial resistance to antibiotics has developed faster than the production of new antibiotics, making bacterial infections increasingly difficult to treat. Scientists worry that a particularly virulent and deadly “superbug” could one day join the ranks of existing untreatable bacteria, causing a public health catastrophe comparable with the Black Death.

  • 1950s pandemic flu virus still a health threat today, particularly to those under 50

    Scientists have evidence that descendants of the H2N2 avian influenza A virus that killed millions worldwide in the 1950s still pose a threat to human health, particularly to those under 50. The study included twenty-two H2N2 avian viruses collected from domestic poultry and wild aquatic birds between 1961 and 2008, making it the most comprehensive analysis yet of avian H2N2 viruses.

  • Seeds from Moringa oleifera trees better then chemicals for purifying water

    Clean water is essential for good health. In many countries it is still difficult to obtain clean water. Even developed countries can benefit from a process that treats waste water without addition of further synthetic chemicals. Seeds from Moringa oleifera trees can be used to purify water. Researchers have discovered that seed material can offer a more efficient purification process than conventional synthetic materials in use today.

  • Stolen nuclear material found intact in Mexico

    Mexican police yesterday said they have found a truck, a white 2007 Volkswagen cargo vehicle, which was stolen Monday by thieves who apparently were not aware that it was carrying toxic radioactive medical material from a hospital to a disposal site. The cobalt-60 the truck was carrying could be used to build a “dirty bomb.” The IAEA said that more than 100 incidents of thefts and other unauthorized activities involving nuclear and radioactive material are reported to the agency annually.

  • Yasser Arafat was not poisoned: French investigators

    French scientific and medical experts rule out possibility that Palestinian leader was poisoned by radioactive polonium-210. A Russian medical team examining tissue samples taken from Arafat’s body reached the same conclusion three months ago. The conclusions of a Swiss medical team were more ambiguous. Leaders of the Palestinian Authority began accusing Israel of poisoning Arafat even before he died, as his health was rapidly declining. Israel has consistently denied the accusation, describing it as “unreasonable and unsupported by facts.”
