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
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
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
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
As humanity continues to carpet bomb the microscopic world with antibiotics, the enemy is fighting back. Antibiotic resistance is on the rise, and that can mean painful or life-threatening infections for those unfortunate enough to come into contact with such organisms. One of the most common re...

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
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
Doses of a human gut microbe helped to reverse behavioural 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 pre... Read More
This episode: Scientists engineered E. coli to seek and destroy pathogens!
(10 MB, 11 minutes)
A bacterium can sense pathogens in the body, swim toward them, and release a deadly biofilm-busting payload. This process is called pseudotaxis, and could be modified for many... Read More
Researchers in Umeå and Uppsala have found that residues of the influenza drug Tamiflu in our environment can make the influenza virus in birds resistant. This can have serious consequences in the event of an influenza pandemic. With more than 14 million SEK from the Swedish Research Councils Fo... Read More
Darwin and the 20th century pioneers of biology would have been astonished to see the countless roles that microbes play in shaping eukaryotic life. From the origins of eukaryotic cells to pharmaceutical products, Life as we know it would be unrecognizable without microbes. Integrating microbes ... Read More
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
Blood clots play an unexpected role in protecting the body from the deadly effects of bacteria by absorbing bacterial toxins, researchers at the University of California, Davis, have found. The research was published Dec. 2 in the journal PLoS ONE.
"It's a significant addition to the short li... Read More

History has repeatedly shown that contagion makes an easy bedfellow with human conflict.
Take the poliovirus outbreak in Syria - and Israel and Egypt too - caused by related strains that can be traced back to Pakistan.
War and insurgency provide the ideal conditions for bacteria and viruse... Read More
The phrase "Twitter feed" is about to take on a troubling hue. The Food Standards Authority would like all British citizens... to keep it up to date with the color of their vomit and much more.
The government wants to keep abreast of the norovirus. This virus -- known in the UK as the winter ... Read More

Researchers at Singapore's Institute of Bioengineering and Nanotechnology (IBN) and California's IBM Research -- Almaden (IBM) have discovered a new, potentially life-saving application for polyethylene terephthalate (PET), which is widely used to make plastic bottles. They have successfully con... Read More
When attacking body cells, bacteria, such as salmonellae or Yersinia (plague pathogens), inject specific bacterial proteins through hollow, syringe-like structures – called injectisomes – into the host cells. These substances reprogram the cells and can thus overcome their defense. From then on,... Read More
