In a new study, scientists at the University of Maryland and the Institut Pasteur show that bacteria evolve new abilities, such as antibiotic resistance, predominantly by acquiring genes from other bacteria.
The researchers new insights into the evolution of bacteria partly contradict the wid... Read More
The assertion that autism is linked to childhood vaccinations has run and run, even as study after study has failed to find such a link, either with MMR vaccines or ones containing thimerosal, an organic compound that contains mercury.
One prominent article fingering thimerosal was “Deadly... Read More
When it comes to breaking down plant matter and converting it to energy, the cow has it all figured out. Its digestive system allows it to eat more than 150 pounds of plant matter every day. Now researchers report that they have found dozens of previously unknown microbial enzymes in the bovine ... Read More
Half of the states have widespread flu activity, reports the Centers for Disease Control and Prevention.
From January 16 to 22, flu activity increased and three flu-related deaths were reported in children, according to the CDC. During this flu season, which started in October, there have bee... Read More
The Health Service was put on red alert yesterday after nearly 400 cases of infection by deadly superbugs were identified in hospitals.
At least five deaths have been linked to the strains of bacteria that are resistant to even the most powerful antibiotics.
Some of the infected patients w... Read More
Antibiotics are met by resistance from germs; so researchers develop new drugs and germs become resistant again.
Now some scientists believe genetics will be the new weapon in the fight, with doctors consulting bacterial genomes when treating disease.
This week a team at the Wellcome Trust... Read More
Ecologist Colin Henderson co-authored a study that may have identified the cause of the honeybee illness that has plagued U.S. bees since 2006. Henderson, 59, is an associate professor of biology at the University of Montana. He and colleagues there found a correlation between colony collapse di... Read More
El Podcast del Microbio" Nº 155 and 156 describes the story of the origin of the name "New Delhi Metallobetlactamase-1" . E... Read More
Can you create an extremophile? The microbes living and thriving at the fringes of the biosphere manage to get by in spite of extreme temperatures, radiation levels, and pressures (did I miss any?) that most other life forms would choke on. But how easy would it be for an organism that prosper... Read More
The type of bacteria that colonize the placenta during pregnancy could be associated with preterm birth and other developmental problems in newborns according to research published in the current issue of the online journal mBio®.
"The fetal inflammatory response appears to contribute to the ... Read More
Google and the iPhone are American inventions. But the first mass-produced gas-electric hybrid car was made in Japan.
And although the United States now fosters a nascent commercial space industry, if you want to speed from city to city on a smooth, fast train, you have to head to Europe.

They give you joy. They give you loyalty. They give you sloppy kisses.
But before you allow Fido or Fluffy to climb into bed with you at night, as an increasing number of Americans are doing, know that they can also give you something else: zoonoses.
In the United States, the most common p... Read More
Sometimes natural selection gets a helping hand from humans. A new study tracing the genetic history of a nasty strain of pneumonia-causing bacteria shows that antibiotics and vaccines helped shape the microbe’s evolution.
In a technical tour de force, an international team of researchers dec... Read More
You may have heard the proclamation before: The next generation of biofuels will be derived from cellulosic plant material. And, in theory, this makes sense. Whereas ethanol can be produced via the fermentation of simple sugars in food crops such as corn or sugarcane, it would be more economical... Read More
As last year's Salmonella outbreak and the unethical practices of egg mogul Jack DeCoster proved, our food supply is not always as safe as expected. One problem is that numerous systems exist for reporting foodborne illnesses on a state by state basis, and the difficulty of analyzing the data ma... Read More

A workhorse of modern biology is sick, and scientists couldn't be happier.
Researchers at Washington University School of Medicine in St. Louis, the Jacques Monod Institute in France and Cambridge University have found that the nematode C. elegans, a millimeter-long worm used extensively for ... Read More
It's commonly known, at least among microbiologists, that microbes have an additional option to living or dying -- dormancy.
Dormant microbes are less like zombies and more like hibernating bears. What isn't known, however, is how large numbers of dormant microorganisms affect the natural env... Read More
A strain of bacteria found in soil is being studied for its ability to convert glycerol - waste from the biodiesel process - into several useful materials. Keerthi Venkataramanan, a student in the University of Alabama in Huntsville's biotechnology Ph.D. program, is developing biological tools t... Read More
Bacteria called Listeria monocytogenes can cause mild food-poisoning symptoms in healthy individuals, but some strains have an enhanced ability to invade the heart, a new study finds.
The ability to infect the heart, possibly causing serious heart disease, may be due to particular proteins on... Read More
