Orange Juice Boosts AIDS Drug - A simple glass of orange juice can greatly enhance the absorption of a potent experimental AIDS drug, reported researchers at the XIth International AIDS Conference.

AIDS: Where are the Basic Scientists? - For one reason or another, many basic scientists appear to be staying away from the XIth International AIDS Conference, a situation that benefits no one, according to noted AIDS researcher Mark A. Wainberg, Ph.D.

HIV in the USA - While the level of HIV infection appears to be leveling off in the US, it has stabilized at a high level, according to new CDC data.

AIDS Research- Some Optimism - While recent clinical trials give some reason for optimism, AIDS researchers, whether working in the lab or in the field in the developing world, face considerable obstacles, said Anthony S. Fauci, M.D., Director, National Institute of Allergy and Infectious Diseases.

Vaccines May Suppress HIV in Kids - New research suggests vaccines can be designed to suppress infection by the human immunodeficiency virus.

New Co-Receptor for HIV - The identification of a new cell receptor, dubbed 'fusin', for HIV could lead to new AIDS treatment strategies, as well as a possible new animal model for HIV infection

MORE AIDS NEWS ARTICLES & INTERNET RESOURCES - Here is a list of AIDS news stories we've covered since 1994, along with a hotlist of Internet resources. For more materials, including teaching resources, conduct a search on keyword AIDS from the Access Excellence Home Page.

Young Source of Bacterial Resistance - Misuse of antibiotics in developing countries is creating a new pool of resistant bacteria- healthy young children- according to a new study.

Ehrlicosis: New Tick Test - As tick season begins, researchers are putting increased focus on granulocytic ehrlichosis, a potentially fatal disease spread by the same tick that spreads Lyme disease.

Water Safety, Quality Called Global Crisis - Worldwide problems with water treatment and delivery pose an increasing risk to human health, says a new report by the American Academy of Microbiology.

Using Enzymes to 'Edit' Faulty Genes - The successful use of enzymes to to repair faulty genes in living cells could lead to entirely new approaches to gene therapy for diseases such as sickle cell anemia.

Research on the Storm Front - Supercomputers and hurricane-hunting high altitiude aircraft are among the tools used by scientists who are investigating how storms develop and how they might better be predicted.

Increased Risk from Environmental Estrogens - The combination of two chemicals commonly found in insecticides and pesticides produces estrogenic effects that are one thousand times more powerful than either individual chemical alone.

Fat Free Sugar for Diabetics - A non-caloric form of sugar called D-tagatose appears to be well tolerated by diabetics and could help in their treatment.

Approaches to Preventing Diabetes - New treatment strategies suggest it may be possible to prevent Type II, or non-insulin dependent diabetes.

ALS Progress - An enhanced understanding of the pathogenesis of ALS is translating into several promising drug treatment approaches for this disabling, always fatal disease.

Bacterial Gene Thieves - The discovery of a multidrug-resistant form of the Streptococcus bacterium that switches its coat to evade detection by the immune system could prove useful in the design of anti-strep vaccines

Intelligent Micromachines - Originally developed to provide better security for nuclear arms, micro-machines now in development offer the potential of everything from better airbags to improved drug delivery.

Dinos Hit Ground Running - Humans. like most other mammals and birds, are born virtually helpless and unable to fend for themselves. Baby dinosaurs, however, may have been quite capable of taking care of themselves.

New BSE Findings - A series of new studies of the genetics of bovine spongiform encephalopathy (mad cow disease) provides some new pieces in the puzzle of prion diseases.

New Method For Imaging DNA - A new method for direct imaging of DNA could lead to faster design of drugs for cancer and other diseases.

Kidney Defects Precede High Blood Pressure - The discovery that inherited defects in the kidney set the stage for hypertension, comes as a major surprise to researchers who had believed the opposite hypothesis- that high blood pressure led to kidney defects.

Deriving Miss Daisy - A comparison of tropical daisy genes across the Pacific suggests plant evolution may occur at a far faster rate than previously believed possible.

Wetlands Under Siege - The rapid destruction of wetland areas around Portland, Ore. may be a harbinger of ecological impacts to come in other fast growing urban areas across the nation, experts say.

Vitamin E Helps Diabetics - High doses of vitamin E appear to reduce the risk for cardiovascular disease in patients with diabetes,

New Toxic Munching Plant - A genetically altered plant with a healthy appetite for heavy metal pollutants could prove a valuable environmental clean-up tool.

Glacial Grasshoppers Yield Clues - A rare find of grasshoppers frozen for 800 years in Rocky Mountain glaciers may yield new clues to help combat modern-day versions of this pesky pest that ravages food and forage crops.

Memory's Molecular Gatekeeper - The discovery of molecular gatekeeper involving memory function offers new opportunities for development treatments for stroke and neurological disorders.

Complete DNA Sequence of Yeast - A worldwide collaboration of more than 100 laboratories has accomplished a significant first in scientific research, the sequencing of the complete genome of a complex organism, Saccharomyces cerevisiae, otherwise known as baker's yeast. researchers.
