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.

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
(from http://www.ted.com) Venice, Italy is sinking. To save it, Rachel Armstrong says we need to outgrow architecture made of inert materials and, well, make architecture that grows itself. She proposes a not-quite-alive material that does its own repairs and sequesters carbon, too. 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.

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.
