Studying the deadly secrets of flu, Ebola, West Nile viruses
In an effort to sort out why some viruses such as influenza, Ebola, and West Nile are so lethal, a team of U.S. researchers plans a comprehensive effort to model how humans respond to these viral pathogens. The goal of the study will be to provide a detailed molecular understanding of what occurs when these viruses infect their hosts, providing a foundation for the design and development of a new generation of drugs to thwart infection by some of the world’s most serious pathogens.

Fukushima-derived radioactivity in seafood poses minimal health risks
Researchers find that the likely doses of radioactivity ingested by humans consuming fish contaminated by radioactive radiation escaping from the debilitated Fukushima reactors fish, are comparable to, or less than, the radiological dosages associated with other commonly consumed foods, many medical treatments, air travel, and other background sources.

Six out of ten people on Earth still lack access to flush toilets, adequate sanitation
It may be the twenty-first century, with all its technological marvels, but six out of every ten people on Earth still do not have access to flush toilets or other adequate sanitation — measures that protect the user and the surrounding community from harmful health effects — according to a new study.

Faster method to identify Salmonella strains
There are more than a million estimated cases of salmonellosis annually in the United States, resulting in approximately 400 deaths, nearly 20,000 hospitalizations and an economic burden of millions of dollars. New method may significantly reduce the time it takes health officials to identify Salmonella strains.

U.S. unlikely to meet its biofuel goals
The Energy Independence and Security Act of 2007 (EISA) mandates that by 2022 the United States derive fifteen billion gallons per year of ethanol from corn to blend with conventional motor fuels. A new study says that if the climate continues to evolve as predicted by the Intergovernmental Panel on Climate Change, the United States stands little to no chance of satisfying its biofuel goals.

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.

Letters containing ricin sent to Mayor Michael Bloomberg, gun-control advocacy group
Two letters sent to Mayor Michael Bloomberg – one to his office in New York, the second to the Washington, D.C. offices of Mayors Against Illegal Guns, a non-profit gun-control group he has founded — contained traces of the deadly poison ricin.

Spokane, Wash. biolab could be closed due to budget cuts
Just two weeks ago, law enforcement agencies credited a bioterrorism laboratory in Spokane, Washington with quickly identifying the substance in several letters mailed to people in town as ricin. These same agencies now say that the biolab could close as a result of budget cuts.

A majority on Earth will soon face severe, self-inflicted water shortage: scientists
A conference of 500 leading water scientists from around the world, held last week in Bonn, issued a stark warning that, without major reforms, “in the short span of one or two generations, the majority of the nine billion people on Earth will be living under the handicap of severe pressure on fresh water, an absolutely essential natural resource for which there is no substitute. This handicap will be self-inflicted and is, we believe, entirely avoidable.”

Smartphone turned into handheld biosensor
Scientists and physicians in the field could soon run on-the-spot tests for environmental toxins, medical diagnostics, food safety and more with their smartphones. Researchers have developed a cradle and app for the iPhone that uses the phone’s built-in camera and processing power as a biosensor to detect toxins, proteins, bacteria, viruses, and other molecules.

Ricin can kill, but there are more potent bioterror weapons
Ricin was in the headlines a few weeks ago, when envelopes containing the poison were mailed to President Obama, Senator Roger Wicker (R-Mississippi), and a Mississippi judge. The threat from ricin is low, however, because ricin cannot poison someone through contact with the skin. To be poisoned, an individual would have to ingest or inhale traces of the poison.
