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....

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.


However, new research shows that a... Read More

C-section may affect type of bacteria baby has

Microbes are with us all our lives, from before the cradle to the grave. And while some are capable of killing us, most of the microbes we carry around — inside and on our skin — are part of a microbial bouquet that makes each of us who we are.

Researchers have been studying the trillions of ... Read More

What's in your shopping bag? Bacteria. (But, hey, it's natural!)

Way to go, all you planet-saving shoppers who've made the switch to reusable bags! But consider: "Reusable" doesn't mean "self-cleaning."

Researchers at the University of Arizona and Loma Linda University queried shoppers headed into grocery stores in California and Arizona, asking them if t... Read More

Manipulating Microbes in the Gut May Remedy Disease and Enhance Health

We are what we eat, but who are "we"? New, high-powered genomic analytical techniques have established that as many as 1,000 different single-celled species coexist in relative harmony in every healthy human gut.

"For each human cell in your body there are 10 microbial cells, most of them liv... Read More

Scientists Discover Source of Essential Nutrients for Open-Ocean Algae

For almost three decades, oceanographers have been puzzled by the ability of microscopic algae ("microalgae") to grow in open-ocean areas where there is very little nitrate, an essential nutrient for the algae.

In this week's issue of the journal Nature, Monterey Bay Aquarium Research Institu... Read More

New Medical Weapons to Protect Against Anthrax Attacks

The 2001 anthrax attacks in the United States are fostering development of a new generation of vaccines, antibiotics, and other medications to protect people against the potentially deadly bacteria in any future bioterrorist incident. That's the conclusion of a sweeping overview of scientific re... Read More
