Jan Zalasiewicz, a lecturer in geology at the University of Leicester, has published a new study looking at the lasting impression made by mankind -100 million years hence.

He takes the perspective of alien explorers arriving on earth - their geologists study the layers of rock, using the many clues to piece together its history over several billion years

DURHAM, N.C. -- Why aren't pregnant women included in most clinical trials?

That's the question posed by leading bioethicists at Duke University Medical Center, Johns Hopkins and Georgetown Universities, who say it's time to confront the challenges that have led to the exclusion of pregnant women from important research that could positively impact maternal and fetal health.

As college students head back to school with gleaming new laptops, some will, unfortunately, see the last of their machine in a library, cafeteria or dorm room. And it's not just college campuses that are hot spots for computer theft, or just students who are the targets. Newspapers recently reported that airports in the United States record hundreds of thousands of laptop thefts annually. Such thefts are not only expensive, they also often mean losing sensitive data.

For years, physicists have been heralding the revolutionary potential of using quantum mechanics to build a new generation of supercomputers, unbreakable codes, and ultra-fast and secure communication networks.

McGill University researchers have discovered the oldest rocks on Earth – a discovery which sheds more light on our planet's mysterious beginnings. These rocks, known as "faux-amphibolites", may be remnants of a portion of Earth's primordial crust – the first crust that formed at the surface of our planet. The ancient rocks were found in Northern Quebec, along the Hudson's Bay coast, 40 km south of Inukjuak in an area known as the Nuvvuagittuq greenstone belt. Their results will be published in the September 26 issue of the journal Science.

(Santa Barbara, Calif.) –– Smaller. Faster. More efficient. These are the qualities that drive science and industry to create new nanoscale structures that will help to speed up computers.

Scientists at the University of California, Santa Barbara have made a major contribution to this field by designing a new nanotechnology that will ultimately help make computers smaller, faster, and more efficient. The new process is described in today's Science Express, the online version of the journal Science.

Boulder, CO, USA – A line of massive boulders on the western shore of Tonga may be evidence of the most powerful volcano-triggered tsunami found to date. Up to 9 meters (30 feet) high and weighing up to 1.6 million kilograms (3.5 million pounds), the seven coral boulders are located 100 to 400 meters (300 to 1,300 feet) from the coast. The house-sized boulders were likely flung ashore by a wave rivaling the 1883 Krakatau tsunami, which is estimated to have towered 35 meters (115 feet) high.

Mahmoud El-Gamal, chair of Rice University's economics department, is available for media interviews this week and into the weekend to discuss the current financial crisis and action Congress is likely to take.

El-Gamal and Amy Myers Jaffe of Rice University's Baker Institute are near completion of a forthcoming book, tentatively titled "Oil, Dollars, Debt and Crises." The book closely examines the world financial marketplace. "It's a book about the petrodollar and the worldwide financial system," said El-Gamal.
