The poster child for basic research might well be a one-celled green algae found in ordinary lakes and ponds. Amazingly, this unassuming creature—called Chlamydomonas—is helping scientists solve one of the most complex and important mysteries of science: How billions of neurons in the brain inte... Read More
Bioengineers at the University of California, San Diego have used the genomic sequences of 55 E. coli strains to reconstruct the metabolic repertoire for each strain. Surprisingly, these reconstructions do an excellent job of predicting the kind of environment where each strain will thrive, the ... Read More
Microbiologists are trying to work out whether use of antibiotics on farms is fuelling the human epidemic of drug-resistant bacteria.
The sight of just one boot coming through the doorway cues the clatter of tiny hoofs as 500 piglets scramble away from Mike Male. “That's the sound of healthy ... Read More
Cast your minds back a few months ago, to when the director of the US Centers for Disease Control and Prevention announced, “We have a very serious problem” with “nightmare bacteria,” and the chief medical officer of the United Kingdom backed him up a few days later, describing a “ticking time b...

A team of researchers led by King's College London has for the first time identified a new gene which may have the ability to prevent HIV, the virus that causes AIDS, from spreading after it enters the body.
Published in Nature today, the study is the first to identify a role for the human MX... Read More
By tinkering with their chemical structures, researchers at the University of California, San Diego School of Medicine have essentially re-invented a class of popular antimicrobial drugs, restoring and in some cases, expanding or improving, their effectiveness against drug-resistant pathogens in...

Doctors say the discovery of a 4-year-old carrier of the H7N9 bird flu virus who shows no symptoms of the potentially lethal virus is a worrying development that could make the spread of the infection more difficult to monitor.
The Beijing Municipal Health Bureau said the boy was detected fro... Read More
A newly discovered fungus that feasts on the skin of amphibians is threatening to decimate a species of salamander in the Netherlands, according to new research.
Fire salamanders are one of the most recognizable salamander species in Europe, and are characterized by their distinct yellow- and... Read More
The bottlenose dolphins are migrating south. So officials in New Jersey thought that they had seen the last of the strandings - animals washing onto beaches, dead or dying - in what has become the largest Atlantic Coast die-off of dolphins in memory.
But on Monday, the body of another dolphin... Read More
Newcastle University scientists have revealed the mechanism that causes a slime to form, making bacteria hard to shift and resistant to antibiotics.
When under threat, some bacteria can shield themselves in a slimy protective layer, known as a biofilm. It is made up of communities of bacteria h... Read More
University of British Columbia researchers have developed a vaccine that may halt the spread of West Nile Virus (WNV) among common and endangered bird species.
WNV, a mosquito borne pathogen, arrived in North America in 1999 and is now endemic across the continent. In 2012 alone, WNV killed 2... Read More
The Kartchner caverns in southeast Arizona are famous for their spectacular limestone rock formations, created by groundwater seeping and dissolving bedrock compounds over thousands of years. For all their beauty, the caverns are extremely harsh environments with no sunlight and precious little ... Read More
Scientists are great at growing E. coli in the lab. They know exactly under which conditions various strains thrive. Unfortunately, there is only so much that can be learned from the bacteria’s behavior in an ideal, isolated and ultimately unrealistic environment. That is why a group of research... Read More
An investigational vaccine appears generally well tolerated and effective against the most common strain of norovirus, reducing the main symptoms of the gastrointestinal (GI) infection, vomiting and/or diarrhea, by 52 percent, suggests research being presented at IDWeek 2013™.
Currently, ther... Read More
The head of the World Health Organization warned the world this week of a new virus, awkwardly dubbed MERS-CoV, found in Saudi Arabia.
"Looking at the overall global situation, my greatest concern right now is the novel coronavirus," Margaret Chan said, calling it "a threat to the entire worl... Read More
We’re driving on a dirt road and my interpreter, one of the friendliest guys I’ve ever met, is absorbed in a conversation with a health worker in our group. Cornfields and rice paddies paint the landscape chartreuse. Donkey carts and herds of goats swerve into the plants when we rumble past. The... Read More
For the past decade, much of the focus in the Arctic has centered on the rate at which ice melts and its ecological impact. Now, as Arctic ice continues to melt, carbon that has been stored in the frozen tundra for thousands of years is creeping up to the surface and exposed to a new element: su... Read More
Two subtypes of human papillomavirus (HPV) prevented by vaccines are half as likely to be found in African-American women as in white women with precancerous cervical lesions, according to researchers at Duke Medicine.
The findings, presented on Oct. 28, 2013, at the 12th annual International... Read More
The NDSU Department of Veterinary and Microbiological Sciences researchers discovered that B-phenylethylamine, or PEA, reduced the number of cells of Escherichia coli in a beef broth. PEA is a substance found in chocolate in trace amounts. Health food stores sell it in pill form to improve peopl... Read More
The H7N9 avian flu strain that emerged in China earlier this year has been subdued for now, but it would be a mistake to be reassured by this apparent lull in infections. The virus has several highly unusual traits that paint a disquieting picture of a pathogen that may yet lead to a pandemic, a... Read More
