AIDS Vaccine Trials Underway - A trial with the gp120 AIDS vaccine now underway in the capital of Thailand should provide the long sought answers regarding the utility of this vaccine candidate. (8 May 1995)

Nun's Brains Yield Clues to Alzheimer's Disease - A long-term study of nuns is providing valuable new clues to the nature of aging and Alzheimer's disease. 7 May 1995)

Vaccines in Vegetable Form - Genetically engineered fruits and vegetables that provide immunity could soon become a reality according to several recent studies. (5 May 1995)

Monster Mollusk Found - Sixty-five million years ago, a giant 12-foot long mollusk lived at the bottom of the sea near Antarctica. The discovery of a complete fossil of the creature, an ammonite known as Diplomoceras maximum, is causing researchers to rethink their ideas on mollusk evolution. (1 May 1995)

DNA Methlyation Provides Cancer Cure - New evidence linking DNA methylation and colon cancer may offer a new way to treat this common malignancy, reported a team of researchers from the Whitehead Institute for Biomedical Research. (1 May 1995)

RNA and the Origins of Life - Hitherto unrecognized properties of RNA add further support to the idea that RNA was the central molecule in the origin of life, report researchers. (26 April 1995)

New AIDS Test Predicts AIDS Progression - A new AIDS test provides clinicians with a way to predict how quickly an HIV-positive person will progress to AIDS, report researchers. 24 April 1995)

Medical Uses For Tobacco - Nicotine in tobacco form accounts for millions of deaths each year from cancer, emphysema and heart disease. Yet, in certain neurologic and psychiatric conditions, nicotine can have useful therapeutic effects, reported scientists at the inaugural conference of the Society for Research on Nicotine and Tobacco. (24 April 1995)

New Vaccine Protects Against Rotavirus - A new vaccine can prevent more than 80 percent of the most severe diarrheal illnesses in children caused by rotaviruses, suggests a large clinical trial. (23 April 1995)

Ectozymes: A Way to Stop Cancer? - The discovery of the gene that encodes a protein that enables cancer cells to spread throughout the body could lead to treatments that would stop cancer in its tracks, reported scientists from the U.S. National Cancer Institute at the annual meeting of the American Association for Cancer Research. 19 April 1995)

Great Famine, Gone - Not Forgotten - One-hundred and fifty years ago a fungus called Phytophthora infestans began a destructive process that would change the course of Irish and, indirectly, world history. The country is now commemorating the 150th anniversary of the potato famine that would lead to the deaths of millions of citizens and the emigration of many millions more.

Garlic Compound Slows Cancer Growth - A compound isolated from garlic has shown potent anti-tumor effects in preliminary studies, reported researchers at Experimental Biology '95, a meeting of 18 scientific societies. (11 April 1995)

New Front Against Lyme Disease - New information on the bacterium that causes Lyme disease will provide a much needed boost to efforts to design diagnostic tests and vaccines for the disease, report researchers from the National Institute of Allergy and Infectious Diseases (NIAID). (10 April 1995)

Ebola Infection Reported - The Center's for Disease Control and Prevention has confirmed a diagnosis of Ebola virus infection in a Swiss researcher who had been working in central Africa. (9 April 1995)

How Passive Smoking Causes Heart Disease - Recent studies provide a better understanding of the mechanisms by which second hand tobacco smoke contributes to the development of heart disease, report researchers from UC San Francisco. 8 April 1995)

New Data on Breast Cancer Gene - The BRCA1 gene, previously implicated in the development of rare familial forms of breast cancer, also appears to play a role in much more common types of non-inherited breast cancers, report researchers from Vanderbilt University Medical Center (4 April 1995)

Jumping Genes Yield Bisexual Fruit Flies - Mutations induced by jumping genes can produce marked changes in the courting behavior in male fruit flies, including bisexual traits, according to a recent collaborative study. (3 April 1995)

AIDS Vaccine Offers Cross Protection in Animal Model - One of the most challenging obstacles facing AIDS vaccine developers is the extensive variability among different strains of the rapidly mutating virus, HIV. Another problem has been the lack of a good animal model for vaccine studies. New research from the National Institutes of Health suggests that neither obstacle is insurmountable. (1 April 1995)
