Blind mice see again

Researchers have restored sight to blind laboratory mice. Using a virus already approved for human gene therapy, the researchers inserted a gene from a light-sensitive bacterium, Natronomonas pharaonis, into cone-cell DNA. Read More

Scientists crack chemical code that controls bacterial swarms

Spanish researchers have discovered a key component of infectious bacteria's battle plan, identifying a protein that tells bacteria in a colony to halt their forward march when antibiotics are present, waiting until the coast is clear before resuming the infection.

Free tests available during National HIV Testing Day

Health groups across the country are preparing for National HIV Testing Day this Sunday.

More than one million Americans are living with HIV, but one in five people don't even know they have it. That's why health officials say it's so important to get checked, and urge everyone to take an HIV... Read More

Bird flu: In the plumage the secret of virus spread success

International team of Italy-US scientists reports discovery of a new mechanism of avian influenza virus circulation and transmission in nature

A team of scientists, led by Mauro Delogu, virologist from the Veterinary Faculty of the Bologna University and researchers from the Istituto Superior... Read More

Soil-Borne Pathogens Drive Tree Diversity in Forests, Study Shows

What determines plant diversity in a forest? It's a question even Charles Darwin wanted to unravel. But most research into forest diversity demonstrates only patterns of species survival and abundance rather than the reason for them -- until now.

A team of researchers led by biologists at the... Read More

Companies Peddling Microbial Cures to Oil Spill Come Calling on Gulf Coast

Superbugs won't save the Gulf Coast. But that won't stop companies from selling them. As crude washes into marshes and beaches along the Gulf of Mexico, several small businesses have been barnstorming to sell local and state officials on what seems like a dream scenario. Douse the oil with our ... Read More

The Exxon Valdez and Bioremediation

As we hear more and more news about the environmental disaster currently underway in the Gulf, there has been much talk about how microbes can be utilized to biodegrade the oil. In this 7 minute video posted on YouTube we see how scientists successfully implemented a bioremediation plan during t... Read More

The Human Genome at 10: What It Did—and Didn’t—Deliver

Happy Birthday, human genome. On June 26, 2000 a group of scientists at the White House announced that they had a working draft of our genetic blueprints. They hadn’t sequenced all our genes; the Human Genome Project and its private-sector competitor Celera Genomics still had some gaps to fill i... Read More

Airway Microbiota and Pathogen Abundance in Age-Stratified Cystic Fibrosis Patients

Abstract - Bacterial communities in the airways of cystic fibrosis (CF) patients are, as in other ecological niches, influenced by autogenic and allogenic factors. However, our understanding of microbial colonization in younger versus older CF airways and the association with pulmonary function ... Read More

Microbiota of the nose and throat: phylum-level similarities, species-level differences

There’s more than one way to skin a cat. The latest paper from mBio reveals that although the bacterial phyla in the nose and throat are somewhat consistent from person to person, the individual species vary a great deal, indicating there is more than one ideal community for these niches, and mo...

The Hand Microbiome: Your Real DNA Fingerprint

In the past 100 years we’ve learned that each one of us has unique fingerprints, and unique DNA sequences. Now through the Human Microbiome Project, we’re learning that every one of us has a unique and identifiable bacterial community not only inside of us, but also growing on our skin as well....

Chronic fatigue syndrome: suspicion is back on virus

A leading scientist at the US National Institutes of Health (NIH) supports the theory that a retrovirus causes chronic fatigue syndrome (CFS) and says that government researchers have independently confirmed the association.

The link between xenotropic murine leukemia virus-related virus (XM... Read More

Small Amount of Common Preservative Increases Toxins from Harmful Bacteria in Food

n response to consumer demand for more natural food, the food industry has reduced the amount of preservatives in food over recent years. A common preservative is acetic acid, which is used to stop bacterial growth in dressings, sauces, cheese and pickles.
