Computer imaging of Archeopteryx skull suggests this dinosaur-bird link could fly
Detailed images of the fossilized skull of an Archeopteryx animal by scientists at The University of Texas at Austin and elsewhere provide strong evidence that the bird predecessor could handle flight maneuvers. Geologist Timothy Rowe and colleagues created 3-D models from computed tomography images, which revealed the relatively large size of the animal's brain and such features as its cortex, where detailed information about feather positions would be used to make body adjustments during flight.

Meteorites rained on Earth after massive asteroid breakup
Using fossil meteorites and ancient limestone unearthed throughout southern Sweden, marine geologists at Rice University have discovered that a colossal collision in the asteroid belt some 500 million years ago led to intense meteorite strikes over the Earth's surface. The research, which appears in this week's issue of Science magazine, is based upon an analysis of extraterrestrial minerals and fossils found in limestone that formed from sea bottom sediments about 480 million years ago.

HAART and heart disease
Highly active anti-retroviral therapy (HAART) for HIV-infected individuals includes the use of combinations of antiretroviral drugs such as protease inhibitors. In a report in the February 3 issue of the Journal of Clinical Investigation Eric Smart and colleagues from the University of Kentucky Medical School in Lexington found that HIV protease inhibitors directly promote atherosclerosis in mice and also induce changes in human macrophage cells like those seen in atherosclerotic lesions.

Geologists' model reveals foundation flaws in bedrock under new urban centers
Before developers decide to make the desert bloom, they better take a look at what's under the surface of the Earth. That's the conclusion of research by Texas A&M University geologist Mohamed Aly, who's using GIS (geographic information systems) techniques to conduct engineering geomorphology assessments of some of Egypt's newest urban developments to predict - and thus avoid - foundation problems stemming from instabilities in the underlying bedrock.

Botanists discover new conifer species in Vietnam
An unusual conifer found in a remote area of northern Vietnam has been identified as a genus and species previously unknown to science. The limestone ridges where the tree grows are among the most botanically rich areas in Vietnam, said Daniel Harder, director of the University of California at Santa Cruz (UCSC) Arboretum and a co-discoverer of the new species. The discovery is published in the current issue of the journal Novon. (2002-06-04)

Rock climbing harms cliff ecosystems
While it stands to reason that rock climbers might harm habitats such as the ancient, stunted forests that grow on cliffs around the world, there has been little unambiguous evidence that this is so. Now the first study to isolate rock climbing from other factors confirms that the sport damages cliff ecosystems. (2002-04-01)

Alaskan terrane shared seaway with Siberia and Ural Mountains
Geologists generally accept that some of Alaska's landscape originated as part of the North American continent, but the origins of the Alexander terrane in southeastern Alaska have been much more vague.
