A University of Sheffield scientist has isolated a bacterium that may cause cancers in those with a genetic pre-disposition to the disease.

Dr Milton Wainwright, of the University’s Molecular Biology and Biotechnology department, researched historical literature and found that, as early as the 1890s, bacteria were believed to cause cancer. Unfortunately, none of the bacteria involved in these studies were ever kept or even named, making it impossible to verify claims about their role

An innovative engineering project could lead to fewer night-time accidents on badly lit roads.

It is developing a revolutionary way of assessing whether roads are equipped with appropriate levels of streetlighting.

The new assessment system is quicker, cheaper and more comprehensive than methods previously used. It can also help local authorities avoid the cost of unnecessary streetlight replacement.

The project is being carried out by engineers at Queen’s Univers

A Mayo Clinic study of more than 41,000 postmenopausal women in Iowa provides new evidence that the most common type of lung cancer in women is more closely linked to smoking cigarettes than previously recognized. The findings of the study will be published in the Dec. 15, 2002 issue of the American Journal of Epidemiology.

Lung cancer has been the leading cause of cancer death in women for more than a decade. In 2000, about 68,000 American women died of lung cancer. That’s compared to

A greater number of large “planetary sized waves” in the atmosphere that move from the lower atmosphere into the upper atmosphere were responsible for the smaller Antarctic ozone hole this fall, according to NASA researchers. The September 2002 ozone hole was half the size it was in 2000. However, scientists say that these large-scale weather patterns in the Earth’s atmosphere are not an indication that the ozone layer is recovering.

Pro Jahr gehen in Deutschland etwa 22 Mio. Paar Kinderschuhe über die Ladentheke. Rund 30 Prozent davon stellen deutsche Firmen her. Neben seinem modischen Aussehen und seiner richtigen Passform ist die Fähigkeit zur Wärme- und Feuchtigkeitsregulation maßgeblich für den Komfort eines Schuhs. Die Füße sollen warm und trocken bleiben und vor äußeren Einwirkungen geschützt werden. Der Abtransport des Fußschweißes durch Socke und S

The broad-scale warming expected from increased greenhouse gases may actually sap the strength of a typical El Niño, according to researchers at the National Center for Atmospheric Research (NCAR) in Boulder, Colorado. In contrast, the average El Niño during the last ice age may have packed more punch than today’s. The scientists have examined the past and future behavior of El Niño using a sophisticated computer model of global climate. They present their results this week at the annual meeting
