A Texas lake that turned blood-red this summer may not be a sign of the End Times, but probably is the end of a popular fishing and recreation spot. A drought has left the OC Fisher Reservoir in San Angelo State Park in West Texas almost entirely dry. The water that is left is stagnant, full of dead fish — and a deep, opaque red. The color has some apocalypse believers suggesting that OC Fisher is an early sign of the end of the world, but Texas Parks and Wildlife Inland Fisheries officials say the bloody look is the result...

Materials scientists at the University of Birmingham have devised a way of making stainless steel surfaces resistant to bacteria in a project funded by the Engineering and Physical Sciences Research Council which culminated this week. By introducing silver or copper into the steel surface (rather than coating it on to the surface), the researchers have developed a technique that not only kills bacteria but is very hard and resistant to wear and tear during cleaning. Bacteria resistant surfaces could be used in hospitals to prevent the spread of superbug infections on stainless steels surfaces, as well as in medical equipment,...

Bacterial poisonAnthrax, septicemia and meningitis are some of the planet's most deadly infections. In part because doctors lack basic insights to prevent and cure diseases caused by so called Gram-positive bacteria. Now, a chemist from the University of Copenhagen has revealed the mechanism behind these deadly infections.By creating a synthetic version of a Gram-bacterial endotoxin, Danish synthetic chemist Christian Marcus Pedersen has made a contribution that'll compel immune biologists to revise their textbooks. More importantly, he has paved the first steps of the way towards new and effective types of antibiotics. Chemist in international collaboration with biologists and physiciansThe research...

There may be no food more American than the burger. And according to meat lovers, there may be no health code regulation less American than North Carolina's rare and medium rare burger ban. From Winston-Salem to Nags Head, meat eaters are unable to order their burgers rare or even medium rare thanks to a state restriction that requires restaurants to cook ground beef to an internal temperature of 155 degrees Fahrenheit. That's enough heat to sufficiently kill dangerous bacteria like E. coli, according to state health officials. But it's also enough heat to kill all of the flavor, according to...

Doctors have discovered that adding sugar to antibiotics increases their ability to knock out persistent staph infections (abstract). Certain types of bacteria called persisters shut down their metabolic processes when exposed to antibiotics. Adding sugar keeps the bacteria feeding, making them more susceptible to drugs. From the article: "Adding such a simple and widely available compound to existing antibiotics enhances their effectiveness against persisters, and fast. One test showed that a sugared up antibiotic could eliminate 99.9 percent of persisters in two hours, while a regular antibiotic did nothing. Doctors believe that this discovery will help treat urinary tract infections,...

Hospital infections kill more Americans each year than AIDS, car accidents and breast cancer combined -- and researchers are searching for solutions. This week, a study of 153 Veterans Affairs hospitals shows that doing a simple swab test to identify and isolate the few patients carrying infection-causing bacteria can save lives. It's called screening, but even more important is cleaning. Studies are rolling in that hospitals need to be cleaner. In fact, if you're visiting a friend or relative in the hospital, don't bring flowers or candy -- take gloves and a canister of bleach wipes. Hospitals do an inadequate...

"Here’s something to think about the next time you stop by the meat counter at your local grocery store – there may be drug-resistant strains of bacteria lurking in that steak or chicken...." A study by the Translational Genomics Research Institute, found that Staphylococcus aureus – a bacteria that causes most staph infections including skin infections, pneumonia and blood poisoning – are present in meat and poultry from U.S. grocery stores at “unexpectedly high rates.”

The joke that's going around is that the Mayans got it wrong: The world is ending this year, not 2012. Here's the lates sign of that. A superbug is spreading around America, and has hit Southern California. LA Times: A dangerous drug-resistant bacterium has spread to patients in Southern California, according to a study by Los Angeles County public health officials. More than 350 cases of the Carbapenem-Resistant Klebsiella pneumoniae, or CRKP, have been reported at healthcare facilities in Los Angeles County, mostly among elderly patients at skilled-nursing and long-term care facilities, according to a study by Dr. Dawn Terashita,...

SAN FRANCISCO -- The seats of some well used methods of public transportation have been analyzed by a biologist and the results might keep commuters on their feet. A supervisor with San Francisco State University's biology lab recently tested the bacterial content of a random BART seat and a Muni seat. The Bay Citizen commissioned the study. On Muni's plastic seats she found two forms of harmless bacteria, and after using an alcohol wipe on the seat no bacteria was detected. But the cloth seats on BART told an entirely different story: tests of the seats on BART revealed fecal...

No, no, no. No no no no no no no no. No, no. No. Fox News broke the story, which ought to make one immediately suspicious — it's not an organization noted for scientific acumen. But even worse, the paper claiming the discovery of bacteria fossils in carbonaceous chondrites was published in … the Journal of Cosmology. I've mentioned Cosmology before — it isn't a real science journal at all, but is the ginned-up website of a small group of crank academics obsessed with the idea of Hoyle and Wickramasinghe that life originated in outer space and simply rained down...

Researchers from the University of Arizona swabbed shopping cart handles in four states looking for bacterial contamination. Of the 85 carts examined, 72 percent turned out to have a marker for fecal bacteria. The researchers took a closer look at the samples from 36 carts and discovered Escherichia coli, more commonly known as E. coli, on 50 percent of them - along with a host of other types of bacteria. Shopping cart handles aren't the only thing you need to worry about when you go to the local supermarket, Gerba added. In other research, he's found that reusable shopping bags...

The teeming trillions of bacteria in the digestive tracts of mice have been shown to affect the animals' brain development and behaviour.Mice bred in sterile environments without these "gut flora" were seen to be more adventurous and less anxious than mice with normal gut flora. The research adds weight to the idea that gut bacteria are a critical part of the overall development of mammals.

Federal study confirms microbes have eaten most of the Gulf Oil Spill A study by researchers from Texas A&M and University of California in Santa Barbara have found that all of the methane gas released from the BP spill in the Gulf of Mexico have been consumed by tiny microbes. Methane gas amounts 100,000 times higher than normal at the time of their release have completely disappeared after only 120 days. Some scientists had raised concerns that dissolved methane and other oil residue would continue to plague the Gulf for years or even decades. This is turning out not...

f First Lady Michelle Obama has her way, every public school cafeteria across this great nation will have a salad bar full of lettuce, carrots, and communism. The First Lady's Let's Move Salad Bars To Schools program aims to put 6,000 kid-sized salad bars in schools. Each salad bar costs $2,500, and the whole program costs $15 million. So on top of promoting a vegetable-y socialist agenda, they're also expensive! (Schools are being encouraged to raise part of the money themselves.) Big government run amock! The goal of course is to hoodwink children into eating their vegetables. >>> The goal...

Every week hundreds of Utahns carry their groceries home in reusable grocery bags. They do it to help the health of the environment, but it may be at the risk of their own health. KSL 5 News pulled out the gloves, the swabs and the culture dishes for a Staying Safe investigation that reveals - you may be carrying more in your bag than you bought. Studies done in other states found some reusable bags have contained samples of e.coli and salmonella. But our tests were negative: no e.coli, no salmonella. The coliforms were another story. Of the 89 bags...

Incredible microbe found in California lakeNasa scientists are set to announce that bacteria have been discovered that can survive in arsenic, an element previously thought too toxic to support life, it can be revealed. In a press conference scheduled for tomorrow evening, researchers will unveil the discovery of the incredible microbe - which substitutes arsenic for phosphorus to sustain its growth - in a lake in California. The remarkable discovery raises the prospect that life could exist on other planets which do not have phosphorus in the atmosphere, which had previously been thought vital for life to begin. But it...

For years, researchers have wondered about a connection between children getting strep throat and later showing symptoms of obsessive-compulsive disorder (OCD). Obsessive-compulsive disorder is a frequently debilitating condition affecting millions of Americans in which those afflicted think repetitive thoughts they don’t want to or perform compulsive, ritualistic behaviors they wish they didn’t have to— ..." The thinking has been that strep throat bacteria trigger the production of antibodies that end up not only targeting strep, but “mistakenly” acting on an enzyme in the brain, which is involved in making brain chemical messengers. In so doing, the antibodies to the strep...

A few scientists noticed in the late 1960s that the marine bacteria Vibrio fischeri appeared to coordinate among themselves the production of chemicals that produced bioluminescence, waiting until a certain number of them were in the neighborhood before firing up their light-making machinery. This behavior was eventually dubbed “quorum sensing.” It was one of the first in what has turned out to be a long list of ways in which bacteria talk to each other and to other organisms.

Scientists have discovered that they can attach tiny studs of silver onto the surface of otherwise harmless bacteria, giving them the ability to destroy viruses. They have tested the silver-impregnated bacteria against norovirus, which causes winter vomiting outbreaks, and found that they leaves the virus unable to cause infections. The researchers now believe the same technique could help to combat other viruses, including influenza and those responsible for causing the common cold. Professor Willy Verstraete, a microbiologist from the University of Ghent, Belgium, who unveiled the findings at a meeting of the Society for Applied Microbiology in London last week,...

Marchetta could not find anyone who regularly cleaned their reusable bags. Marchetta brought the lab results to Dr. Michelle Barron, the infectious disease expert at the University of Colorado Hospital. "Wow. Wow. That is pretty impressive," said Barron. Barron examines lab results for a living. "Oh my goodness! This is definitely the highest count," Barron commented while looking at the bacteria count numbers. She admitted she was shocked at what was found at the bottom of the bags. "We're talking in the million range of bacteria," she said. Marchetta used swabs provided by a local lab to test several grocery...
