Study highlights respiratory disorders prevalent in the Middle East

Lung diseases in the Middle East range from the centuries-old pulmonary tuberculosis (TB) to modern manifestations caused by chemical warfare. A new paper now available in Respirology, a journal of the Asian Pacific Society of Respirology, provides pulmonologists and patients with the first comprehensive review of respiratory illnesses specific to the Persian Gulf region, and the challenges in treating them. This unique review is the first of its kind in this topic and will serve as an important landmark reference article.

Higher cigarette taxes don't deter all smokers

Montreal, July 13, 2011 — Raising taxes on cigarettes, a public health measure used by governments to encourage people to quit, doesn't motivate all smokers to stop the deadly habit.

A study on the long-term impact of taxing cigarettes, led by two Concordia University economists and published in the International Journal of Environmental Research and Public Health, found higher taxes do prompt low-and middle-income earners to quit.

Yet price increases don't persuade wealthier smokers or those aged 25 to 44 to butt out.

Penn researchers show single drug and soft environment can increase platelet production

PHILADELPHIA — Humans produce billions of clot-forming platelets every day, but there are times when there aren't enough of them, such as with certain diseases or during invasive surgery. Now, University of Pennsylvania researchers have demonstrated that a single drug can induce bone marrow cells called megakaryocytes to quadruple the number of platelets they produce.

Localized reactive badger culling raises bovine tuberculosis risk, new analysis confirms

Localised badger culling in response to bovine tuberculosis (TB) outbreaks increases the risk of infection in nearby herds, according to a new analysis.

The study, by researchers at the Medical Research Council Centre for Outbreak Analysis and Modelling at Imperial College London, is published today in the Royal Society journal Biology Letters.

The findings come as the Government prepares to decide whether to license farmers to organise the widespread culling of badgers over areas of 150 square kilometres or more in western England.

One-third of central Catalan coast is very vulnerable to storm impact

Researchers from the Polytechnic University of Catalonia (UPC) have developed a method for evaluating the vulnerability of coastal regions to the impact of storms. The method, which has been applied on the Catalan coastline, shows that one-third of the region's coasts have a high rate of vulnerability to flooding, while 20% are at risk of erosion.

Fewer aphids in organic crop fields

Farmers who spray insecticides against aphids as a preventative measure only achieve a short-term effect with this method. In the long term, their fields will end up with even more aphids than untreated fields. This has been reported by researchers at the Biocenter of the University of Würzburg in the scientific journal PLoS One.

Sea urchins cannot control invasive seaweeds

Exotic marine species, including giant seaweeds, are spreading fast, with harmful effects on native species, and are increasingly affecting the biodiversity of the Mediterranean seabed. Some native species, such as sea urchins (Paracentrotus lividus), can fight off this invasion, but only during its early stages, or when seaweed densities are very low.

Long-term NSAID use by hypertensive patients with CAD increases risk of adverse events

New York, NY, July 12, 2011 – A study published in the July issue of The American Journal of Medicine, reports that among hypertensive patients with coronary artery disease, chronic self-reported use of non-steroidal anti-inflammatory drugs (NSAIDs) was associated with an increased risk of adverse events during long-term follow-up. Long-term NSAIDs use is common for treatment of chronic pain.

VOICE study will continue as it considers what action to take after results of 2 trials

PITTSBURGH, July 13, 2011 – Today, researchers from two major HIV prevention trials announced favorable results of an approach called oral pre-exposure prophylaxis, or PrEP. One of these trials, the Partners PrEP Study, has provided the strongest evidence yet of PrEP's effectiveness.

Pivotal study in Africa finds that HIV medications prevent HIV infection

In a result that will fundamentally change approaches to HIV prevention in Africa, an international study has demonstrated that individuals at high risk for HIV infection who took a daily tablet containing an HIV medication – either the antiretroviral medication tenofovir or tenofovir in combination with emtricitabine – experienced significantly fewer HIV infections than those who received a placebo pill. These findings are clear evidence that this new HIV prevention strategy, called pre-exposure prophylaxis (or PrEP), substantially reduces HIV infection risk.

Wind-turbine placement produces tenfold power increase, Caltech researchers say

PASADENA, Calif.—The power output of wind farms can be increased by an order of magnitude—at least tenfold—simply by optimizing the placement of turbines on a given plot of land, say researchers at the California Institute of Technology (Caltech) who have been conducting a unique field study at an experimental two-acre wind farm in northern Los Angeles County.

Separated for 20 million years: Blind beetle from Bulgarian caves clarifies questions

One of the smallest ever cave-dwelling ground beetles (Carabidae), has recently been discovered in two caves in the Rhodopi Mountains, Bulgaria, and described under the name Paralovricia beroni. The beetle is completely blind and is only 1.8-2.2 mm long. The study was published in the open access journal ZooKeys.

Natural gas produced from fine milling of precious metals

Roger Anderson, President of X9 Gold Development, Inc., announced today that multiple tests conducted over the past 18 months have demonstrated that carbon in precious metal ores can be converted to natural gas (methane) during fine milling utilizing X9 Gold's Bubble Mill Technology.

"Over 250 milling processes on a variety of ores have yielded the production of natural gas (methane) as a by-product of the milling process. The amount of natural gas generated seems to be in direct proportion to the carbon content of the ore. "

Family planning in conflict

Many areas of the world are at war and both the conflict and aftermath have dire consequences for the health of people affected. New research published in BioMed Central's open access journal Conflict and Health reports that while women in war-torn areas want access to family planning, these services are often not available at local hospitals or health centers. This can lead to further deprivation and unintended pregnancy.

Newly discovered molecule essential to resetting 'body clocks'

Research has shown that light is the key to getting our 'body clocks' back in sync and now a new study exploring the resynchronisation mechanism in insects has discovered a molecule essential to the process.

Researchers from Queen Mary, University of London looked at the impact of light on the circadian clocks (commonly known as 'body clocks') of fruit flies. They identified a novel molecule, QUASIMODO (QSM), which was intrinsically involved in relaying light-information to the flies' inner clocks.
