Current methods of reducing arsenic contamination of water are not effective
Arsenic is now recognized to be one of the world’s greatest environmental hazards, threatening the lives of several hundred million people. Naturally occurring arsenic leaches into water from surrounding rocks and once in the water supply it is both toxic and carcinogenic to anyone drinking it. New research finds that most of the current technologies used around the world to reduce arsenic contamination are ineffective.

New malaria test kit would help global elimination efforts
A new, highly sensitive blood test that quickly detects even the lowest levels of malaria parasites in the body could make a dramatic difference in efforts to tackle the disease in the United Kingdom and across the world, according to new research.

Rendering mosquitoes immune to malaria parasites
Scientists have established an inheritable bacterial infection in malaria-transmitting Anopheles mosquitoes that renders them immune to malaria parasites. The strategy holds promise for malaria control efforts.

Silica particles purify water by acting as oil magnets
Engineers develop an innovative method designed to purify water through the rapid removal of oily pollutants. The technology involves the deployment of surface engineered silica particles, which act as oil magnets in water, adsorbing oil, yet repelling water.

Office implementing Obamacare avoids furloughs
Gary Cohen, the director of the Center for Consumer Information and Insurance Oversight, said Wednesday that his office will not be furloughing its workers due to the federal budget cuts known as the sequester. His office is in charge of implementing most of President Obama’s healthcare law.

Preventing bugs from becoming antibiotic-resistant
About 440 000 new cases of drug-resistant tuberculosis emerge annually, causing around 150 000 deaths. New research finds that bacteria can evolve resistance more quickly when stronger antibiotics are used. The rate of evolution of antibiotic resistance speeds up when potent treatments are given because resistant bacterial cells flourish most during the most aggressive therapies.

Fighting superbugs with a new genre of antibodies
In an advance toward coping with bacteria that shrug off existing antibiotics and sterilization methods, scientists are reporting development of a new family of selective antimicrobial agents that do not rely on traditional antibiotics.

U.S. hospitals shipping sick immigrants back to their home countries
Hundreds of immigrants who are in the United States illegally end up in the hospital only to find out they will be sent home through a removal system run by hospitals trying to avoid the high cost of treating illegal immigrants.

Bird flu mutation study offers vaccine clue
Scientists have described small genetic changes that enable the H5N1 bird flu virus to replicate more easily in the noses of mammals. So far there have only been isolated cases of bird flu in humans, and no widespread transmission as the H5N1 virus cannot replicate efficiently in the nose.

New device will quickly detect botulinum, ricin, other biothreat agents
Researchers are developing a medical instrument which will be able quickly to detect a suite of biothreat agents, including anthrax, ricin, botulinum, shiga, and SEB toxin. The device, once developed, approved by the Food and Drug Administration (FDA), and commercialized, would most likely be used in emergency rooms in the event of a bioterrorism incident.

Same-day water test keeps beaches open, swimmers’ health protected
With warm summer days at the beach on the minds of millions of winter-weary people, scientists are reporting that use of a new water quality test this year could prevent unnecessary beach closures, while better protecting the health of swimmers.

More than 10,000 pesticides approved by EPA without rigorous review
Congress allowed the Environmental Protection Agency (EPA) to use what is called “conditional registration” to approve pesticides deemed especially beneficial for food production – even before all the toxicity tests have been completed. Congress intended conditional registration to be used only sparingly, but the EPS has been using the loophole in a wholesale fashion to approve 65 percent – or more than 10,000 – of the 16,000 pesticides submitted to it for approval. The EPA cannot easily track the history of conditionally approved pesticides to determine whether required toxicity data was submitted, whether that caused a dangerous use of a pesticide to be cancelled, or whether the uses or restrictions should be modified based in such data.

Predicting disease outbreaks to protect soldiers -- and civilians
Researchers from Johns Hopkins University and the Pentagon develop a new method to predict dengue fever outbreaks several weeks before they occur. The method extracts relationships between clinical, meteorological, climatic, and socio-political data. It can be used in any geographical region and extended to other environmentally influenced infections affecting public health and military forces worldwide. DoD is currently evaluating the method for use in mitigating the effects of infectious disease in various operational settings.

Hidden dune filters treat coastal stormwater runoff
When it rains, untreated stormwater can sweep pollutants into coastal waters, potentially endangering public health. Now researchers have developed low-cost filtration systems that are concealed beneath sand dunes and filter out most of the bacteria that can lead to beach closures.

Huge Areas May Face Possibly Fatal Heat Waves if Warming Continues
A new assessment warns that if Earth’s average temperature reaches 2 degrees C over the preindustrial average, widespread areas may become too hot during extreme heat events for many people to survive without artificial cooling.
