Using off-the-shelf chemical compounds, scientists for the first time have constructed the entire genome of a bacterium, a key step toward their ultimate goal of creating synthetic life forms, researchers reported today. The man-made DNA was nearly identical to the natural version on which it was based -- with minor modifications to identify it and render it harmless to people, according to the study in the journal Science. The research team at the J. Craig Venter Institute in Rockville, Md.

Biologists have converted one species of bacterium into another by replacing all of its DNA, a critical step toward their ultimate goal of designing entire organisms from scratch, according to a study published Thursday. The transplanted DNA took over its single-cell host in about three days. The resulting bacterium was indistinguishable from the donor species, the researchers reported in the online edition of the journal Science.

Hunting for the elusive cure for the common cold, scientists have decoded the genomes of all known strains of the human rhinovirus, the main cause of the malady that makes millions miserable each year. But don't toss out the chicken soup yet. There is so much diversity among the strains that hopes for a vaccine or a treatment that would prevent or cure every cold are slim, according to the scientists' study, published online Thursday in the journal Science.

In a bold but uncertain bid to spur cancer treatment, federal medical researchers announced a $100-million project Tuesday to begin cataloging the disease's molecular underpinnings. The Cancer Genome Atlas, as the project is called, will start as a three-year pilot program to identify the genes behind two or three types of cancerous tumors. If the research proves promising and affordable, it would be expanded to study thousands of cancerous tumors.

Even before Celera Genomics and the public Human Genome Project announce that they have completed the first versions of the human genetic code, there is a dispute brewing over who will get scientific credit. Specifically, editors at the prestigious journal Science are now struggling over whether to publish Celera's results over the objections of some scientists in the Human Genome Project.

Fourteen years ago, the diving vessel Alvin plucked a bizarre, single-cell creature from a volcanic vent 1,000 miles off the coast of Baja California. There, under crushing pressures 245 times greater than at sea level and at temperatures just a few degrees below the boiling point of water, the Methanococcus jannaschii and its ancestors had thrived for up to 3 billion years.

A team of researchers has deciphered the genome of the rhesus macaque, one of the most widely used primates in medical research because it is susceptible to many of the diseases that attack humans. Coming two years after the sequencing of the chimpanzee genome, the feat, reported today in the journal Science, provides new insight into what makes humans human.

A private company that is racing to decipher the human genetic code accused leaders on Tuesday of a parallel, publicly funded effort of deliberately scuttling negotiations to join forces. In a letter to representatives of the public Human Genome Project, J. Craig Venter, the president of Celera Genomics, accused them of spreading misinformation about Celera's desire to control distribution of their combined genetic research data.

The most profound social question raised by science in the 20th century has been how to wield the power that man acquired upon splitting the atom. Now, as a new century approaches, science is poised to present society with an equally momentous question: how to use man's growing ability to "split" or genetically alter DNA, the chemical code that guides the development of all life on Earth.

Molecular biologist J. Craig Venter's announcement last week sounded like something out of a science-fiction film (or a Michael Crichton thriller): His team created living bacteria cells from genetic material designed by computer and assembled in a laboratory. Venter didn't exactly pull a Dr. Frankenstein — bacteria aren't complex organisms, and Venter's team didn't start completely from scratch. Still, his feat raises difficult questions about the expanding boundaries of science and the nature of life.
