A new study casts further doubt on the role of a retrovirus, XMRV, in human disease, adding weight to the possibility that earlier studies finding a link between the virus and cancer and chronic fatigue syndrome may have been wrong. In the study, researchers from the National Cancer Institute and Johns Hopkins Medicine report being unable to find any evidence of the retrovirus in nearly 800 prostate cancer samples. "It is possible that XMRV is not actually circulating in the human population," the team wrote in its paper published by the journal Cancer Research last week.

In what may prove to be the first major breakthrough in the fight against the mysterious and controversial disorder known as chronic fatigue syndrome, researchers reported today that they have found traces of a virus in the vast majority of patients with the disease, commonly known as CFS. The same virus has previously been identified in at least a quarter of prostate tumors, particularly those that are very aggressive, and has also been linked...

There is no cure for AIDS, no good treatment to control its symptoms for long periods and no vaccine to prevent it, for one major reason: HIV, the human immunodeficiency virus that causes the disease, is a sloppy housekeeper when it comes to tending its genetic endowment. Every time HIV replicates, it makes mistakes, at least one error per generation of the virus. Within a few generations, it can begin to take on subtly different characteristics.

Government scientists have developed an unusual new form of gene therapy to treat inoperable brain tumors and plan to begin human trials this summer. The new approach, which has cured brain tumors in rats, takes advantage of the fact that brain cells do not normally divide and multiply, while tumor cells multiply rapidly. Researchers at the National Cancer Institute injected the tumors with mouse cells containing a specially modified virus that infects only dividing cells.

While painstakingly factual, Dominique Lapierre's new history of the AIDS epidemic is actually fictional in its approach--a gripping adventure story that succeeds by virtue of its skillful manipulation of plot, suspense and character. Far from being a straightforward chronology of red-letter dates in the spread of the disease, it is an eminently readable pastiche of literary genres: of the detective story, in its engaging portrayal of scientific sleuths stalking the biological culprit, hot on the trail of new clues; of the spy story, in its riveting account of international espionage, with medical pioneers such as Robert Gallo and his French counterpart, Luc Montagnier, swept up in a James Bond thriller as they snipe at each other across the Atlantic, each claiming to have discovered the virus; of the Harlequin romance, in its purplish descriptions of love blossoming in laboratories, of eyes locking over Bunsen burners and Petri dishes; and even of hagiography, in its moving profiles of Mother Teresa and the armies of courageous health-care providers who have withstood the harrowing challenges of AIDS.

A new virus that appears to have similarities to the AIDS virus has been isolated from a patient with Sjogren's syndrome, an uncommon ailment that causes dryness of the mouth and eyes, according to researchers at Tulane University School of Medicine in New Orleans.
