Here I remember a person who a great deal of influence on my views about microbiology in the classroom, and the laboratory: the late Abigail Salyers. RIP, Abigail. Read More
Bacteria are found in large numbers all over the human body where there is a channel to the outside world, for example in the gut, lungs, and surface of the skin. I’ve always thought that actually inside the human body was a bacteria-free environment unless an infection was raging so I was very ... Read More
From cow burps to tree hiccups and melting permafrost, the potent greenhouse gas methane is produced in myriad ways. Now we can add another one to the list: electricity-generating microbes. The finding could one day allow us to control the generation of methane.
Methanosaeta microbes are one ... Read More
Colorectal cancer patients have fewer beneficial gut bacteria and more harmful microbes than those without the disease, researchers from the New York University School of Medicine report in Friday’s edition of the Journal of the National Cancer Institute.
While previous research had suggested... Read More
Boston researchers are reporting the return of the HIV virus in two patients who had become virus-free after undergoing bone marrow transplants, dashing hopes of a possible cure that had generated widespread excitement.
The rebound of the virus shows its persistence, and that it can hide in p... Read More
In this blog post, I describe some "rules for academics" as well as my own "rules for research." I hope that readers find them useful and perhaps a bit humorous. Read More
Our mouths are a delicate balance of good and bad bacteria. When we clean our teeth, the aim is to knock out cavity-causing bacteria, while allowing beneficial oral bacteria to thrive. Now, researchers have developed a sugar-free candy, which contains dead bacteria that bind to bad bacteria, pot... Read More
Takele Abayneh Tefera's doctoral research project has uncovered a genetic divergence between the fish pathogen Edwardsiella tarda and Edwardsiella tarda type strain.
He has also identified phenotypic markers that distinguish one from the other. The fish pathogenic strain is now classified as ... Read More
Measles may seem like a distant threat in the United States, but the Centers for Disease Control and Prevention are warning the disease still poses a danger to U.S. residents.
The CDC fears that because measles is so prevalent overseas, people who travel are bringing the virus back to U.S. sh... Read More
HIV has reappeared in the blood of two Boston patients who scientists had hoped had been cured of their infections.
This disappointing development, reported by The Boston Globe's Kay Lazar, is yet another cautionary tale of how researchers can never afford to underestimate the human immunodef... Read More
Bacteria may lack a true immune system, but this does not leave them defenseless against bacteriophage viruses and other pathogens. A system of genomic sequence elements called clustered regularly interspaced short palindromic repeats (CRISPR) and various CRISPR-associated proteins (Cas) help to... Read More
What happens when you use tiny electromagnetic coils to shift the position of light-scattering bacteria? In the hands of a couple of science-minded artists, you get an intriguing "Living Mirror."
I have a new favorite artist: bacteria. Imprinted onto cell phones, it can look like flowers, or ... Read More
Doses of a human gut microbe helped to reverse behavioral problems in mice with autism-like symptoms, researchers report today in Cell. The treatment also reduced gastrointestinal problems in the animals that were similar to those that often accompany autism in humans.
The work builds on prev... Read More

Scanning electron micrograph of a murine macrophage infected with Francisella tularensis strain LVS. Macrophages were dry-fractured by touching the cell surface with cellophane tape after critical point drying to reveal intracellular bacteria. Bacteria (colorized in blue) are located either in t...

years of fighting the deadly and incurable virus, scientists think they may be able to find a way to really kill it. On Monday, the White House and the National Institutes of Health announced a new, $100 million effort to try to find a cure.
In the latest study, researchers tested a modified ... Read More
Bacteria grow faster if they feed each other. The division of labour is more efficient than a struggle through life without help from others – this is also true for microorganisms. Researchers from Research Group Experimental Ecology and Evolution at the Max Planck Institute for Chemical Ecology... Read More
Delivering healthy bacteria in a pill could help patients harboring out-of-balance microbial communities. Yogurt eaters already know that not all bacteria are bad for you. They may not realize that some bacteria are so important that one day people may fight off disease with pills filled with ba... Read More
Slothful response from regulators and manufacturers means antibiotic resistance is missed. Bacteria that are resistant to almost all antibiotics are dreaded by physicians and patients alike. Finding such microbes in a hospital is bad enough, but failing to detect them can lead to something much ... Read More
