Fire fighters tackling the blazes that have ravaged Portugal are doing so with the aid of a satellite data-link.

For the first time, ESA’s satellite Artemis has been used to support an emergency request under the International Charter on “Space and Major Disasters”.
Portugal’s civil protection unit (SNPC) was able to receive information and groups of images that showed the scope of the fires. The data, transmitted from ESA’s Earth observation satellite, Envisat, via the Artemis d

If you’re hunting for illegal drugs, you don’t have to leave your computer desk to find them. A simple internet search will turn up dozens of websites that let you order your drug-of-choice for home-delivery.

In fact, if you search for “no prescription codeine” through one of the standard computer-search systems, the odds are almost fifty-fifty that the first site you hit will provide an instant opportunity to buy drugs illegally.

That finding by researchers at the University of

There’s a lot said about a woman’s ticking biological clock, but male biology doesn’t age as gracefully as men might like to think.

By analyzing sperm from men of various ages, scientists from the McKusick-Nathans Institute for Genetic Medicine at Johns Hopkins have discovered that older men’s sperm is more likely to contain disease-causing genetic mutations that also seem to increase a sperm’s chances of fertilizing an egg.

The findings, which appear in t

On a high hilltop terrace in Oaxaca, Mexico, a team of Field Museum archaeologists discovered a 1,500-year-old underground tomb while excavating a palace-like residence. Although it was near the end of their excavation season, they dared not leave the tomb unexplored. News of this find at El Palmillo was sure to get around, and looting would follow. As it was, workers had to guard the tomb every night until the tomb was excavated.

Data from a five-year study suggests that limited-field radiation therapy (radiation directed at the tumor site) may be as effective as whole-breast radiation therapy in preventing breast cancer recurrence in women treated with breast-conserving surgery. The study appears in the August 20 issue of the Journal of the National Cancer Institute.

Whole-breast radiation therapy is part of standard treatment for women with early-stage breast cancer who have undergone breast-conserving surgery. Ho

A new study settles a long-standing dispute about the genesis of an endangered species. With scant fossil evidence supporting a prehistoric presence, scientists could not say for sure where Borneo’s elephants came from. Did they descend from ancient prototypes of the Pleistocene era or from modern relatives introduced just 300–500 years ago? That question, as Fernando et al. report in an article that will appear in the inaugural issue of PLoS Biology (and currently available online at http://bio
