New study identifies emergence of multidrug-resistant strain of salmonella

A new study has identified the recent emergence of a multidrug-resistant strain of Salmonella that has a high level resistance to ciprofloxacin, a common treatment for severe Salmonella infections. The study, led by François-Xavier Weill, MD, and Simon Le Hello, PharmD, at the Pasteur Institute in France, is published in The Journal of Infectious Diseases and is now available online.

Researchers map minority microbes in the colon

They make up less than one-hundredth of 1 percent of the microbes that live in the colon, but the bacteria and archaea that sop up hydrogen in the gut are fundamental to colon health. In a new study, researchers take a first look at these "hydrogenotrophic" microbes, mapping where they live and how abundant they are in different parts of the lower intestine.

Scientists Stunned by Surface of Asteroid Vesta

The first close-up pictures of the massive asteroid Vesta reveal a northern hemisphere littered with craters -- including a trio nicknamed "Snowman" -- and a smoother southern half, researchers reported Monday. Running along the asteroid's equator are deep grooves -- a surprise to scientists who did not expect to see such features. "We're seeing quite a varied surface," said chief scientist...

Recognizing Voices Harder for People with Dyslexia

Pick up the phone and hear, "Hey, what's up?" Chances are, those few words are enough to recognize who's speaking -- perhaps unless you have dyslexia. In a surprise discovery, researchers found adults with that reading disorder also have a hard time recognizing voices. The work isn't just a curiosity. It fits with research to uncover the building blocks of literacy and how they can go wrong....

CDC: One death, 76 Illnesses Linked to Ground Turkey

Federal officials say one person has died from salmonella poisoning that appears to be linked to eating ground turkey, but the government so far has declined to say who produced the meat or initiate a recall. Seventy-six people in 26 states have been made sick from the same strain of the disease, which the federal Centers for Disease Control and Prevention says is resistant to many commonly...

Scientists Discover Elusive Oxygen Molecules in Space

Scientists have discovered oxygen molecules in deep space in a region of the Orion nebula, some 1,500 light years from the Earth, the U.S. National Aeronautics and Space Administration (NASA) announced Monday. The discovery was made with European Space Agency's Herschel Space Observatory, which used large telescope and infrared detectors to find the elusive molecules. Individual atoms of...

Study Shows Best Places To Protect Marine Mammals

From sea otters to blue whales, marine mammals are under stress from climate change, ocean acidification, hunting and other threats. Researchers have identified 20 important sites around the world where they say conservation efforts should concentrate. Marine mammals are widely distributed in the oceans and some freshwater locations, but 11 of the conservation sites are home to creatures found...

A toss of the dice reveals the truth

In a new study published in the Proceedings of the Royal Society B, researchers show how a simple toss of the dice can help to bring out honest answers when people are asked difficult questions.
