Satellites can help the EU monitor climate change, address international crises and contain natural disasters. Today in Brussels EU Research Commissioner Philippe Busquin and Mr Antonio Rodotà, the Director General of the European Space Agency (ESA), officially opened a large stakeholder consultation forum aiming at the definition of European needs to enhance global monitoring for environment and security (GMES). 250 participants, representing users, suppliers and researchers, addressed poli

The effect of extremely low frequency electromagnetic fields (ELF-EMF), such as those emitted around high-voltage transmission lines on human health, is controversial. Some studies suggest an association between exposure to ELF-EMF and incidence of leukaemia, although little direct evidence exists that exposure causes damage to biological molecules. A new study, published in the Cancer Cell International, presents experimental evidence to show that extremely low frequency electro-magnetic fields can

Studies of cirrus clouds by some 450 scientists may lead to improved forecasts of future climate change. During July in southern Florida, scientists from NASA’s Goddard Space Flight Center, Greenbelt, Md. will join others to investigate high tropical cirrus clouds composed of tiny ice crystals.The researchers hope to determine how the clouds form, how they limit the amount of sunlight reaching the surface of the Earth and how they trap heat rising from the surface and lower atmos

Researchers from the National Cancer Institute (NCI) have found that women in a large study who used estrogen replacement therapy after menopause were at increased risk for ovarian cancer. The report was published in the July 17, 2002, issue of JAMA.* The scientists followed 44,241 women for approximately 20 years. Compared to postmenopausal women not using hormone replacement therapy, users of estrogen-only therapy had a 60 percent greater risk of developing ovarian cancer. The risk increased with

What happens when a large meteor crashes into the Earth? The impact of a large meteorite releases an enormous amount of energy that evaporates, melts and fractures areas surrounding the impact over distances that can range over hundreds of kilometers. Although the subject of abundant recent interest, little is directly known about the propagation of damage during these events.

Three researchers from the Hebrew University of Jerusalem have come up with a new picture of damage propagation, whi

The annual sunburn is still a tradition for many Americans, with nearly 60 percent of young adults reporting at least one sunburn in the past year, according to a new study.

Sun damage is the leading preventable cause of both the most deadly form of skin cancer, melanoma, and of the most common forms, basal cell and squamous cell carcinomas. Skin cancer is the most common form of cancer, occurring in more than 1 million Americans annually. Sunburn represents severe skin damage and
