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
A fungus that decimates white pines has mutated and can now infect immune and resistant plants, say researchers.
This change is alarming to researchers, growers, loggers, and forest managers.
White pine blister rust (WPBR) infects white pines and Ribes, a plant genus that include gooseberr... 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...

There is much that should be remembered about those days of intensive exploratory work and much of it using very simple methods and instruments. There was a remarkable amount of sharing of current work and results without much concern for primacy, which was automatically recognized. Communicatio... 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
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
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
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
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
A group of Israeli researchers has succeeded in isolating a protein that kills bacteria, in what is a first step toward developing a substitute for antibiotics. The substance isolated by a Tel Aviv University team prevents bacteria from dividing, thus destroying them and combatting infections. “... 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
It is well known that aquatic birds are a major reservoir of influenza A viruses, and that pandemic human influenza virus strains of the past century derive viral genes from this pool. The recent discovery of two new influenza A viruses in bats suggests that this species may constitute another r... 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
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
Researchers have found that a commonly used anti-fungal treatment increases susceptibility to severe influenza infection in mice. This treatment deactivates an important protein that protects against viral infections such as influenza.
Amphotericin B is an important anti-fungal treatment for ... Read More
Several African nations could strike a major blow against malaria by sacrificing the efficacy of some older drugs. Can they make it work?
It is September in southeastern Mali, and Louka Coulibaly is standing in the shade of a squat, concrete building, giving instructions to a dozen men and wo... 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
Some time ago, we asked this Talmudic Question: Can you think of a place on Earth where there is free water but no microbes? (A sterile flask of nutrient broth in a lab, the insides of the body, or an IV bag in a hospital don't count.) Someone answered that perhaps deep in Antarctica there would... Read More
Tiny electrical wires protrude from some bacteria and contribute to rock and dirt formation. Researchers studying the protein that makes up one such wire have determined the protein's structure. The finding is important to such diverse fields as producing energy, recycling Earth's carbon and min... Read More
