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
Seafloor-dwelling bacteria may hitch a ride on methane bubbles seeping from deep-sea vents, preventing the methane from reaching the atmosphere by eating it up, new research suggests.
The findings, presented here today (Dec. 9) at the annual meeting of the American Geophysical Union, could he... 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
Children hospitalized for pneumonia have similar outcomes, including length of stay and costs, regardless of whether they are treated with “big gun” antibiotics such as ceftriaxone or cefotaxime or more narrowly focused antibiotics such as ampicillin or penicillin, according to a Vanderbilt stud...

Eat candy and fight tooth decay. What a sweet concept, right?
Well, microbiologists in Berlin are trying to make that dream a reality.
They've created a sugarless mint that's aimed at washing out cavity-causing bacteria from your mouth. And the candy works in a curious way: It's spiked wit... Read More
The genome of viruses is usually enclosed inside a shell called capsid. Capsids have unique mechanic properties: they have to be resistant and at the same time capable of dissolving in order to release the genome into the infected cell. The scientists of the International School for Advanced Stu... 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
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
Scientists at Emory Vaccine Center have found a link between immunity induced by vaccination and an ancient way that cells adapt to scarcity, a link that could help researchers develop vaccines against challenging infections such as HIV or malaria.
Researchers studying immune responses to the... 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
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
One would assume offhand that the pathways for synthesis and assembly of the major constituents of a bacterial cell “talk to each other,” i. e. they are tightly interwoven processes. Tampering with the biosynthesis of one should affect all the others, right? Wouldn’t you expect, for instance, th... 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...

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

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
