For the first time, scientists have ascribed a date - 1434 A.D., plus or minus 11 years - to the parchment of the controversial Vinland Map, possibly the first map of the North American continent.

New study shows passive cigarette smoke at least doubles risk of cancer in cats
Cats living in homes where people smoke cigarettes are more than twice as likely as other cats to acquire a deadly form of cancer known as feline lymphoma, according to a first-of-its kind study in cats conducted by scientists at Tufts University School of Veterinary Medicine and the University of Massachusetts.

UK scientists crack lobster shell colour puzzle
UK researchers announced a first this week when they reported their discovery of how lobsters change colour from the blue-purple of their ocean-floor camouflage to the distinctive orange-red when cooked.

Genetic markers key to identifying schizophrenic patients who can benefit from clozapine
Individual variation in response to medications remains a major problem within the healthcare system.

The Vinland Map shows its true colors; scientists say it's a confirmed forgery
A new study provides the first definitive proof that the controversial Vinland Map is a 20th-century forgery, not a 15th-century relic drawn by Viking explorers.

Adult stem cells selectively delivered into the eye and used to control angiogenesis at TSRI
A team of researchers from The Scripps Research Institute (TSRI) has discovered a way to use adult bone marrow stem cells to form new blood vessels in the eye or to deliver chemicals that will prevent the abnormal formation of new vessels.

In research detailed in the current issue of Science magazine, a team of Rice University chemists led by fullerene discoverer and Nobel laureate Richard Smalley describes the first observations of fluorescence in carbon nanotubes.

Questions arise as more older Americans outlive driving privilege
As people live longer and more older drivers give up their driving privileges, family, friends and public officials may find themselves asking, as it was in a popular film,

Kristin Scott, Ph.D., a postdoctoral fellow and research scientist in the Center for Neurobiology and Behavior at Columbia University Health Sciences, has been named a 2002 Burroughs Wellcome Fund career awardee in the biomedical sciences.

Singapore's Ministry of Education to improve life sciences education
Cold Spring Harbor Laboratory's Dolan DNA Learning Center (DNALC) and the Ministry of Education of the Republic of Singapore have signed a Memorandum of Understanding commencing a multi-year collaboration to develop two DNALC sister institutions in an effort to boost life sciences education in Singapore.

The link between medicine, science and art
A Scottish physician will discuss the relationship between science, medicine and art.

Panel advises easing selection criteria to boost supply of donor hearts
Transplant centers should relax some of the organ selection criteria to increase the supply of transplantable hearts, according to an expert panel of heart transplant surgeons, cardiologists, and organ procurement specialists.

Nutrigenomics and metabolomics
Scientists have known that dietary patterns are strongly linked to the development of seven of the ten top causes of morbidity and mortality in the United States, primarily cardiovascular diseases, cancer, and diabetes.

New gene may be breast-specific cancer markers
Men age 50 and older routinely ask their physician to perform a test for prostate-specific antigen (PSA) to detect the presence of prostate cancer.

A laser-based spectometry screening tool may provide early and efficient detection of breast cancer
Breast cancer remains the most commonly diagnosed cancer among women in the United States.

New molecular template makes virtue of variation
A uneven molecular coating - nanoparticles of gold in a layer that changes from very dense to very sparse across a silica surface of selected molecules - will allow improvements in a wide range of processes and devices.

University of Georgia researchers link increased risk of illness to sewage sludge used as fertilizer
Burning eyes, burning lungs, skin rashes and other symptoms of illness have been found in a study of residents living near land fertilized with Class B biosolids, a byproduct of the human waste treatment process.

Air pollution linked with risk for exercise-induced heart damage
Breathing polluted air, especially smoky exhaust that billows from factory smokestacks and the tailpipes of some diesel-powered buses and trucks, is bad for people with heart disease, according to the first study of its kind reported in today's rapid access issue of Circulation: Journal of the American Heart Association.

Sex genes of fish disrupted by common household products
Scientists have found that the problem of fish endocrine disruption by traces of household products is worse than expected because the compounds work against the sex gene in the brain of fish rather than at estrogen receptors in other tissues.
