Now, attempts ar... Read More

Mothers can pass traits to offspring through bacteria’s DNA

It’s a firmly established fact straight from Biology 101: Traits such as eye color and height are passed from one generation to the next through the parents’ DNA.

But now, a new study in mice by researchers at Washington University School of Medicine in St. Louis has shown that the DNA of ba... Read More

When strep throat is something else: Forgotten bacterium is the cause of many severe sore throats in young adults

New research from the University of Alabama at Birmingham suggests that Fusobacterium necrophorum more often causes severe sore throats in young adults than streptococcus — the cause of the much better known strep throat. The findings, published today in the Annals of Internal Medicine, suggest ... Read More

NIH Ebola study in macaques provides timeframes for post-mortem viral stability

To determine how long Ebola virus could remain infectious in a body after death, National Institutes of Health (NIH) scientists sampled deceased Ebola-infected monkeys and discovered the virus remained viable for at least seven days. They also detected non-infectious viral RNA for up to 70 days ... Read More

Oil Eating Microbes Have Worldwide Underground Connections

Living deep underground ain't easy. In addition to hellish temperatures and pressures, there's not a lot to eat. Which is why oil reservoirs are the microbes’ cornucopia in this hidden realm.

Microbes feast on many oil reservoirs, but it has been unclear how the micro-organisms got to those ... Read More

Fecal transplants may up risk of obesity onset

Fecal microbiota transplantation can be effective for recurrent Clostridium difficile infection, but new-onset obesity could follow transplant of stool from an overweight donor, a new study finds

"Fecal transplant has helped a lot of people who have run out of other options," Dr. Colleen R. K... Read More

Happy Microbial Valentines Day---In Words of Living Light!

In this short blog post, I "write" on Petri dishes with bioluminescent bacteria to create words and poems in "living light." I also write a haiku to quorum sensing in the same style! Read More

Should We Continue to Feed Antibiotics to Livestock? (infograph)

Since the 1950s farmers have fed antibiotic growth promoters (AGPs) to livestock. Overusing these substances can create superbugs, pathogens that are resistant to multiple drugs and could be passed along to humans. Mindful of that, companies such as Perdue Farms have stopped using the drugs to m... Read More

Thames study: rivers can be a source antibiotic resistance

Rivers and streams could be a major source of antibiotic resistance in the environment.

The discovery comes following a study on the Thames river by scientists at the University of Warwick’s School of Life Sciences and the University of Exeter Medical School.

The study found that greater n... Read More

Common gum-disease bug may also give cancer a boost

What do your mouth and your behind have in common? They're linked by a bug that we thought was usually benign, but may in fact have a much darker side.

Fusobacterium nucleatum is a common bacterium that lives in our mouths, often without causing any ill effects, although it is also frequently... Read More

MRSA on Spectra agar

Pictured here are blue colonies of Methicillin-resistant Staphylococcus aureus (MRSA) growing on Remel Spectra MRSA medium. Spectra media contains a chromogen that yields a blue color as a result of phosphatase activity. The phosphatase enzyme is present in many staphylococci, including Staphylo... Read More

Bacterial Armor Holds Clues for Self-Assembling Nanostructures

Imagine thousands of copies of a single protein organizing into a coat of chainmail armor that protects the wearer from harsh and ever-changing environmental conditions. That is the case for many microorganisms. In a new study, researchers with the U.S. Department of Energy (DOE)’s Lawrence Berk... Read More

Darwin's Finches Get Their Genomes Sequenced

Researchers have sequenced the genomes of all 15 species of Darwin’s finches, revealing a key gene responsible for the diversity in the birds’ beaks. The study, published online in Nature this week, also redraws the family tree of these iconic birds, whose facial variations helped Charles Darwin... Read More

Key to blocking influenza virus may lie in a cell’s own machinery

Viruses are masters of outsourcing, entrusting their fundamental function – reproduction – to the host cells they infect. But it turns out this highly economical approach also creates vulnerability.

Researchers at Rockefeller University and their collaborators have found an unexpected way the... Read More
