People Are Human-Bacteria Hybrid

A group of British scientists believes people should be viewed as 'superorganisms,' made of conglomerations of human, fungal, bacterial and viral cells. It's a sensible view, given that human bodies contain more than 500 bacterial species. By Rowan Hooper.

Evolution has gotten faster, and scientists think they know why: Microbes are swapping DNA from one species to another, giving the Darwinian process an added boost.

Human skin teems with a zoo of strange microbes in colonies that are nearly unique from person to person and many of which are practically unknown to science, new research finds. Some of the bugs are permanent residents, while others come and go.

When it comes to DNA, a human is closer to a chimpanzee than a mouse is to a rat. Yet tiny differences sprinkled throughout the genome have made all the difference, giving humans agriculture, language, art, music, technology and philosophy -- all the achievements that make us profoundly different. Until recently, there was no way to unravel these crucial differences, but that's rapidly changing.

U.S. scientists say they have analyzed the genetic makeup of an entire community of bacteria that live inside an unusual marine worm.

Evolutionary experiments on microbes are under way in many laboratories and scientists can observer bacteria adapt over 40,000 generations of living in a beaker.

Scientists said yesterday they had transplanted a microbe's entire, tangled mass of DNA into a closely related organism, a delicate operation that cleanly transformed the recipient from one species into the other.

WASHINGTON -- Any two people may be roughly 99 percent identical at the genetic level. But the small differences are what tantalize scientists, and now they plan to map the DNA of 1,000 people worldwide to examine human genetic variation.

Researchers say they have created the entire genome of a bacterium by stitching together its chemical components.

The sophistication of the human brain is not simply the result of steady evolution, according to new research. Instead, humans are truly privileged animals with brains that have developed in a type of extraordinarily

It's another step in the quest to create artificial organisms: Scientists have synthesized the complete DNA of a type of bacteria. The experiment, published online Thursday by the journal Science, isn't a living germ, just its genetic structure.

Researchers have assembled the entire genome of a living organism -- a bacterium -- in what they hope is an important step to creating artificial life.

Michigan scientists say the bacteria and fungi in a person&#39;s gastrointestinal tract have a great deal to do with his or her sensitivity to allergens.

Humans are likely to catch more than one form of mad cow disease, experiments in mice suggest. But the good news is that some people may have a genetic make-up that protects them against the disease.
