Trade, science, risk, precaution: Issues for Seattle
Has the international community failed to heed Britain's hard won experience on food safety, risk and consumer confidence? This would appear to be the case from the World Trade Organisation's current handling of risk issues. In a letter to be published this week in the prestigious science journal Nature(1), ten leading UK environmental researchers point to some serious weaknesses in the WTO's current approach to risk assessment and product safety.

Novel anti-cancer agent shows minimal side effects with preliminary evidence of tumor shrinkage
On November 16, 1999, researchers will present data on an ongoing Phase I clinical trial during the AACR-NCI-EORTC International Conference in Washington, DC. The data shows that CCI-779, a derivative of rapamycin, an immunosuppresive agent, is well-tolerated and may have antitumor activity.

Geography and physician caseload are key factors in oophorectomy rates, according to Yale study
Whether or not a woman's ovaries are removed during hysterectomy depends partly on where she lives and her surgeon's experience, according to a Yale School of Medicine study. Published in the December issue of Obstetrics & Gynecology, the study raises concerns that women are not being presented with the information needed to make the decision to remove or keep their ovaries.

Jupiter's atmosphere gives clues on how solar system started
A new analysis of data collected by the Galileo spacecraft's suicide plunge into Jupiter's roiling atmosphere has stamped a huge question mark over the prevailing models of how our solar system formed. The finding has been put forward by an international team of scientists.

Do reassuring computers give pilots a false sense of security?
Prompts by computer systems designed to reduce human error in aircraft cockpits or nuclear plants can have the opposite effect. In this new study, American researchers found that those prompted by a computer performed no better than those who relied on instruments alone.

Puzzle of galactic evolution solved
Massive clouds of gas, discovered long ago but only recently identified as being within the margins of the Milky Way, play a key role in the ability of the galaxy to churn out new stars by raining gas onto the plane of the galaxy, a new report suggests.

First science results from giant Hobby-Eberly Telescope reported
The commissioning phase for the innovative William P. Hobby- Robert E. Eberly Telescope (HET) in West Texas has ended and the early operations phase had begun, marking the beginning of regular use of the HET for science. The first paper based on observations with the HET is scheduled to be published in January 2000. The telescope's early results are in the areas of spectroscopic surveys and time-domain astrophysics.

Drawing on his professional, as well as his personal experience, a University of Maryland School of Medicine physician has written the first set of comprehensive, concise and practical guidelines for primary care doctors to help their patients with Type I diabetes to prevent complications. The 20 guidelines are published in the November issue of American Family Physician, a journal of the American Academy of Family Physicians.
