Climate change will impact infectious diseases worldwide, but questions remain as to how

As climatologists weather the IPCC controversy, another storm is brewing, and this one is filled with not with bloggers but with beasts, bugs and bacteria. It is the potential plague of infectious diseases—threatened to be made worse, many scientists propose, by projected changes in the Earth's ... Read More

Researchers Examine Plant’s Ability To Identify, Block Invading Bacteria

Understanding how plants defend themselves from bacterial infections may help researchers understand how people and other animals could be better protected from such pathogens.

That’s the idea behind a study to observe a specific bacteria that infects tomatoes but normally does not bother the... Read More

UCLA engineers develop faster method to detect bacterial contamination in coastal waters

Currently, beachgoers are informed about water-quality conditions based on results from the previous day's sample. Scientists must collect samples in the field, then return to a lab to culture them for analysis — a process that takes a minimum of 24 hours.

Now, engineers from the UCLA Henry ... Read More

Foodborne Illness Costs US $152 Billion Annually, Landmark Report Estimates

A new study by a former U.S. Food and Drug Administration (FDA) economist estimates the total economic impact of foodborne illness across the nation to be a combined $152 billion annually.

The Produce Safety Project, an initiative of The Pew Charitable Trusts at Georgetown University, publish... Read More

Probing life’s extremes in Yellowstone

Idaho National Laboratory biologist Frank Roberto squats on a gravelly patch of ground in Yellowstone National Park. At his feet, scalding water churns in a mustard-yellow pool the size of a wheelbarrow. Roberto reaches in with a plastic vial and scoops up a half-cup.

“That’s a good sample,” ... Read More

Mini Magnets Comprise Ancient Bacteria

Scientists in Manchester, UK have found a clean and green way of making tiny magnets for high tech gadgets—using natural bacteria that have been around for millions of years. The work by a team of geomicrobiologists from the Univ. of Manchester paves the way for nanometer-size magnets – used in ... Read More

Nanofactories monitor bacteria communication


Scientists in the US have developed a microdevice that investigates how bacteria communicate with each other to enhance their resistance to drugs.

Bacteria communicate in a process called quorum sensing, in which they secrete small signalling molecules called autoinducers. When bacteria pr... Read More

Call for Nominations Closes June 30 for the 2010 Awards for Excellence in Inter-American Public Health

Prevention: Older Women Are Not Likely to Benefit From Cervical Cancer Vaccine

Women older than 40 are unlikely to get much benefit from the vaccine for the virus that causes cervical cancer, a new study reports.

The vaccine for human papillomavirus, or HPV, is recommended for women up to age 26 and girls as young as 9. To determine whether older women might be protect... Read More

Tuberculosis: North Korea Develops TB Laboratory With Help From American Doctors

With help from scientists from Stanford University’s medical school, North Korea has developed its first laboratory capable of detecting drug-resistant tuberculosis, scientists involved in the project said last week.

Tuberculosis surged in the Democratic People’s Republic of Korea during the... Read More

Parents' vaccination fears remain high

Numerous studies have debunked the theory that childhood vaccines cause autism, and autism researchers are now, for the most part, focusing on other potential causes of the disorder. But one in five parents still believe that vaccines may cause autism, according to a study released online Sunday... Read More

Virginia Reports No Additional CWD Positives; Response Planning Underway

The Virginia Department of Game and Inland Fisheries (VDGIF) has received laboratory results from all chronic wasting disease (CWD) samples collected through the 2009-2010 hunting season, and no additional positives were found. Since 2002, nearly 5,000 samples have been collected in Virginia, an... Read More

Rising Threat of Infections Unfazed by Antibiotics

A minor-league pitcher in his younger days, Richard Armbruster kept playing baseball recreationally into his 70s, until his right hip started bothering him. Last February he went to a St. Louis hospital for what was to be a routine hip replacement.

By late March, Mr. Armbruster, then 78, was ... Read More

Could Mini Labs and Plant-Based Vaccines Stop the Next Pandemic?

The H1N1 virus's rapid spread worldwide last year exposed the weaknesses in the global system for swiftly developing, manufacturing and distributing vaccines for newly identified strains of influenza. In Texas, researchers are attacking the first two of these problems through Project GreenVax, ... Read More

Toilet Seats: Can You Catch Infections from Them?

Recently in the news, there was a noted “rash” of toilet seat rashes caused from contact with harsh cleaning chemicals that rubbed against the bottoms and thighs of toddlers. While these skin eruptions were caused by direct irritation, it reminds me of why so many women, including myself, never ... Read More

Mars's Environment Shown to Be Hostile, but Not Untenable for Earthly Microbes

Microbes similar to those on Earth would have a tough time surviving the harsh environment of Mars, but it is not inconceivable that they could persist there given a little protection, according to a new study. The finding supports similar, previous work and lends credence to the theory that if ... Read More

Cholera - a model problem solved?

Studying cholera just got a little easier, thanks to a new (old) animal model. For years, cholera research has relied on some less than ideal animal models: infant mice, which don't develop the diarrhea characteristic of severe cholera infection, and infant rabbits, which require surgery to inf...

Novel Compound Found Effective Against Avian Influenza Virus

A novel compound is highly effective against the pathogenic H5N1 avian influenza virus, including some drug-resistant strains, according to new research led by a University of Wisconsin-Madison virologist.

The work, published in the Public Library of Science journal PLoS Pathogens on Feb. 26,... Read More

In Blitz to Kill One Kind of Infectious Bacteria, Other Untreatable Strains Emerge

Move over MRSA; a new battery of Gram-negative bacteria are quietly carving out big names for themselves, killing thousands of hospital patients each year as doctors look on with few effective tools to fight them. What’s worse, though these resistant strains are spreading, there are no effectiv... Read More

Cannabinoid receptor activation blocks HIV Tat protein induced macrophage migration: a new avenue for therapeutics

We all are very familiar with the effects of cannabinoid receptor stimulation on the body. Relaxation, pain relief, and increased appetite probably come first to mind. These psychoactive effects result from activation of the CB1 receptor found on cells in the brain by tetrahydrocannabinol (THC)... Read More
