After five years of toil, a consortium of several hundred U.S. researchers has released a detailed census of the myriad bacteria, yeasts, viruses and amoebas that live, eat, excrete, reproduce and die in or on us. Described in two papers in Nature and a raft of reports in other journals, the data released Wednesday describe microbes of the skin, saliva, nostrils, guts and other areas of 242 adults in tiptop health. The $170-million, federally funded Human Microbiome Project also cataloged the genes contained within this zoo of life.

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 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.

The not-so-distant prospect that scientists will be able to create new forms of life in the lab raises ethical and safety challenges, but progress in the field should not be hobbled by premature restrictions, a panel appointed by President Obama said in a report to be released Thursday. The President's Commission for the Study of Bioethical Issues acknowledged in its first report to the Obama White House that "do-it-yourselfers" ? individual scientists and small labs working without institutional backing or restraints ?

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.

The first draft of the entire human genome ultimately will bring a wealth of scientific knowledge about ourselves. But it could also bring a heap of trouble. Controversial advances that push society to the edge of the scientific frontier frequently pose ethical dilemmas before public policy has had a chance to address them, bioethicists say.
