Geologists show how wetlands can clean up acid mine drainage
University of Cincinnati geologists studying wetlands in Indiana and Ohio have identified key factors which determine constructed wetlands will be effective in cleaning up acid mine drainage.

Why is cloning so hard?
Although in recent years our papers and magazines have been rife with images of Dolly, Copy Cat, and the like, the reality is that cloning mammals is still an extremely inefficient endeavor.

Emory University will conduct clinical trial of anthrax vaccine regimen
Emory University is one of five sites nationwide selected by the CDC to conduct a clinical trial of an anthrax vaccination regimen.

Food & Agriculture Biosecurity Initiative announced by incoming executive dean at Rutgers
A Food & Agriculture Biosecurity Initiative was announced today by Adesoji Adelaja, incoming executive dean of agriculture and natural resources at Rutgers.

Blocking adhesion protein may reduce lung damage from radiation
A study in mice suggests that lung inflammation, lung damage, and diminished lung performance caused by radiation therapy for lung cancer may be reduced by eliminating a protein called ICAM-1.

Pitt researchers find gender differences in the mental health care of children
There are substantial gender differences in the mental health care of children, according to a study published in the May issue of the Archives of Pediatrics & Adolescent Medicine.

Mayo Clinic researchers find useful test for identifying patients
In the past, when a seemingly healthy child collapsed on the basketball court during the heat of the game, parents and medical professionals were sometimes left with few explanations of why.

Study raises questions on widespread prescribing of diabetic footwear
Medicare pays for therapeutic footwear for thousands of people with diabetes each year, but researchers report in the May 15 Journal of the American Medical Association that for many of these patients regular good-quality shoes may work just as well in preventing foot ulcers.

Freezing cancer cells makes them prime targets for anti-cancer drug, new study finds
While cryosurgery and bleomycin have both been used separately as cancer treatments, putting them together may be a more effective way to stop cancer cells cold, according to a new study.

Insect pest of potatoes Tecia solanivora hits crops in Latin America and the Canary Islands
Lepidopteran Tecia solanivora, an insect pest, is currently devastating potato crops in Latin and Central America.

University of South Florida team conducts trial for HIV vaccine
The University of South Florida College of Medicine has begun the human trial of a new AIDS vaccine that proved to slow the disease in monkeys.

Scientists find protein at the intersection of genetics, development, and environment
Environmental stress can reveal hidden genetic variation in plants, resulting in novel traits that might provide an alternative to genetic modification of crops, researchers report in the journal Nature.

Other highlights in the May 15 issue of JNCI
Other highlights include a study suggesting that a modified virus may help improve delivery of gene therapy for ovarian cancer, a study showing that increased levels of a growth factor binding protein may be associated with reduced lung cancer risk, a study suggesting that environmental factors may influence the degree of gene methylation in liver tumors, and a study suggesting that electro-gene therapy may enhance the delivery of an antitumor protein for treating cancers.

Jonathon Knight receives ASM Communications Award
Jonathan Knight, a contributing correspondent for Nature, has been named the recipient of the 2002 American Society for Microbiology Public Communications Award.

2002 U.S. Physics Olympiad Team announced
24 Students from 15 states have been selected as some of the brightest physics and math students in the country.

Research suggests diabetes drug being prescribed even when contraindicated
Some doctors prescribe metformin, the most widely used type 2 diabetes treatment drug, for patients also suffering from congestive heart failure or kidney dysfunction or both despite clear warnings on drug packaging not to do so, a new study indicates.

Gene therapy breakthrough offers hope to patients with inherited high cholesterol levels
New research published in BMC Molecular Biology explains how a new technique for introducing genes into mammalian cells using the virus responsible for warts could be a major step forward in developing gene therapy treatments for people with familial hypercholesterolemia (FH), a genetic disease that affects around 12 million people worldwide.

GlaxoSmithKline Drug Discovery and Development Award 2002
GlaxoSmithKline (GSK) is offering $500,000 in unrestricted awards for innovative HIV/AIDS drug research.

HHMI international research scholars to meet in Queensland, Australia
Leading biomedical scientists from around the world will meet June 25-28 in Palm Cove, Queensland, Australia, to discuss research ranging from the genetic origins of cancer to new treatments for infectious diseases.

Combinatorial chemistry spurs development of new materials
Combinatorial chemistry creates vast numbers of compounds by simultaneously reacting a set of components in thousands of different combinations.

Gene that's key to cloning success also hints at serious hurdles to reproductive cloning
Scientists at the University of Pennsylvania have found that the activity of a single gene is a powerful predictor of whether newly cloned mammalian embryos will survive and thrive, but the gene's sporadic expression in cloned mouse embryos casts fresh doubt on prospects for reproductive human cloning.

Extreme climate variance sped extinction of local butterfly populations, researchers say
The last two Jasper Ridge populations of Bay checkerspot butterflies, subspecies Euphydryas editha bayensis, went extinct in 1991 and 1998.

Blocking gene may reduce lung scarring caused by radiation therapy
Eliminating a gene that regulates inflammation can significantly reduce long-term scarring caused by radiation therapy to the chest, Vanderbilt-Ingram Cancer Center investigators report.

Can we learn about sex from animals?
In her new book 'Sexual Selections: What We Can and Can't Learn about Sex from Animals' (University of California Press, 2002), Marlene Zuk, professor of biology at UC Riverside, argues that while animals do display a lot of interesting variation, not all of it can be extrapolated to explain human behavior. is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to
