In plant and animal innate immunity, like many of the dances of life, it takes two to tango. A receptor molecule in the plant pairs up with a specific molecule on the invading bacteria and, presto, the immune system swings into action to defend against the invasion of the disease-causing microbe...

Your body is home to 10 times as many microbes as its own cells. But they can be quite picky about where they will settle – and what other bacteria they'll share fences with.
That's the conclusion of the most comprehensive map ever of the microbial communities flourishing in the human body.

A short Q&A session that regularly runs in the New York Times. This week, pets and H1N1 are discussed by Dr. Louise Murray, director of medicine at the A.S.P.C.A. Bergh Memorial Animal Hospital in New York City. Read More
Many hands—or many flagella—make light work.
In studies of the motion of tiny swimming bacteria, scientists at the U.S. Department of Energy's Argonne National Laboratory found that the microscopic organisms can stir fluids remarkably quickly and effectively. As a result, the bacterial flagel... Read More
Vets in the US state of Iowa said a household cat had tested positive for swine flu - the first known case in the world of the new pandemic strain spreading to the feline population.
The domestic shorthair, a 13-year-old castrated male, apparently caught A(H1N1) off its owners - two of the th... Read More
n the future, bacteria could harness solar energy to provide power for automobiles if an ASU project recently granted $5.2 million by the U.S. Department of Energy succeeds.
A program in the energy department chose only 37 of 3,500 initial applicants to receive grants.
ASU professor Willem... Read More
Planarians may be lowly flatworms, but the tiny crawlers possess powers that even superheroes would envy. Cut off the worm’s head or tail, and a new one sprouts to replace it. In the flatworm’s body, nerves, muscles, connective tissues, and whole organs regenerate when damaged or removed.
“T... Read More
An international research team led by investigators at the Beijing Genomics Institute-Shenzhen reported online in Nature Genetics yesterday that they have sequenced the draft genome of the domestic cucumber plant, Cucumis sativus.
The team used a combination of Sanger and Illumina methods to ... Read More
Overweight people get heart disease and diabetes – and more severe swine flu – because their fat triggers inflammation, an immune response meant to fight infection. Now the protein responsible for this sequence of events may have been found.
Jerrold Olefsky and colleagues at the University of... Read More
For many Americans, the fear of swine flu has made everyday acts like going to work, going to school or getting on a plane feel fraught with danger — even more so since President Obama recently declared swine flu a national emergency.
Now, even Mickey Mouse is being looked at with suspicion.

Bioengineering students from around the world converged on MIT this weekend in what has become an annual ritual in synthetic biology--iGEM, the international genetically engineered machines competition. Among the finalists this year were "GluColi", a new generation of glue made by bacteria, a bi... Read More
Like savvy Wall Street money managers, bacteria hedge their bets to increase their chances of survival in uncertain times, strategically investing their biological resources to weather unpredictable environments.
In a new study available online and featured on the cover of today's issue of Ce... Read More
For thousands of years an undesirable and persistent companion has been travelling with man wherever he goes. Mycobacterium leprae, the bacterium that causes leprosy, has only one known natural host -- humankind. And because of man's many travels, this bacillus has colonized the entire earth. It... Read More

Without ever leaving your laboratory or office, you can learn from expert scientists and key decision-makers hundreds of miles away. Each teleconference is an interactive live broadcast i... Read More
Backers of algae-based biofuels tout the simplicity of their feedstock. Sunlight and water are all that's needed to convert carbon dioxide into fuel.
Now, some scientists are testing the notion that sunlight might be optional.
Researchers at the Missouri University of Science and Technolog... Read More
Systemic lupus is the most common form of the autoimmune disease, lupus, which afflicts about 5 million people worldwide and causes a slew of symptoms including fever, pain and swelling. Now, sufferers of systemic lupus may be closer to a new drug to treat their symptoms, according to the result... Read More
Imagine that a simple test could tell whether you were going to come down with the flu or a cold even before you get hit by a sore throat, runny nose or fever.
Scientists at Duke University here and at other research centers have been working to develop such a predictive test by delving deep ... Read More
Researchers from the University of Copenhagen and the Technical University of Denmark along with other collaborators in Denmark and the US found that the bacterium Pseudomonas aeruginosa can 'switch on' production of molecules that kill white blood cells -- preventing the bacteria being eliminat...
