Return to Europa: A closer look is possible
12-13-2007 · EurekAlert!New research brings scientists closer to exploring the ice-covered ocean of Europa, one of Jupiter's moons. New methods in measuring gravity and magnetic fields, new radar sounding techniques, new technology being field tested in Antarctica, and findings of lower radiation levels and the presence of carbon dioxide (a key ingredient for life) on Europa make the moon a tantalizing prospect for exploration, as scientists explain at the 2007 meeting of the American Geophysical Union.

- Prototype space probe prepares to explore Earth's deepest sinkhole
03-07-2007 · EurekAlert!
Scientists return this week to the world’s deepest known sinkhole for tests of a NASA-funded robot called DEPTHX, designed to survey and explore for life in one of Earth’s most extreme regions and potentially in outer space. DEPTHX's technology could aid future space probes of Europa, where scientists believe deep holes in the ice could hold extraterrestrial life.

- Researchers demonstrate way to control tree height
06-18-2007 · EurekAlert!
Forest scientists at Oregon State University have used genetic modification to successfully manipulate the growth in height of trees, showing that it's possible to create miniature trees that look similar to normal trees -- but after several years of growth may range anywhere from 50 feet tall to a few inches. This is a "proof of concept" that tree height can be readily controlled by genetic engineering techniques.

- Astronomers get first look at Uranus's rings as they swing edge-on to Earth
08-23-2007 · EurekAlert!
An edge-on view of Uranus' rings, possible only once every 42 years, shows that the dust distribution has changed significantly since Voyager 2 took photos in 1986. Keck and Hubble observations show the inner rings more clearly as the bright outer rings dim, and may discover new moons that shepherd the ring debris.

Yogi Berra supposedly suggested that when you come to a fork in the road, you are supposed to take it.That's just what planetary scientists studying the rich data set from the Galileo Mission to the outer solar system are doing now. They're taking the fork.William B. McKinnon, Ph.D., professor of earth and planetary sciences in Arts & Sciences at Washington University in St. Louis, says the community suffers from an embarrassment of riches

- Fixed versus growth intelligence mindsets: It’s all in your head, Dweck says
02-16-2007 · EurekAlert!
Stanford psychologist Carol Dweck says that people's self-theories about intelligence have a profound influence on their motivation to learn. People who have a "fixed" theory are mainly concerned with how smart they are -- they prefer tasks they can already do well and avoid ones on which they may make mistakes and not look smart. In contrast, people who believe in a "growth" theory of intelligence want to challenge themselves to increase their abilities, even if they fail at first.

- Life cycle assessment essential to nanotech commercial development
03-20-2007 · EurekAlert!
Life cycle assessment (LCA) —a cradle-to-grave look at the health and environmental impact of a material, chemical, or product—is an essential tool for ensuring the safe, responsible, and sustainable commercialization of nanotechnology, U.S. and European experts conclude in a new report issued today.

- How to look at dinosaur tracks
04-30-2007 · EurekAlert!
A new study appearing in the May issue of The Journal of Geology provides fascinating insight into the factors geologists must account for when examining dinosaur tracks. The authors studied a range of larger tracks from the family of dinosaurs that includes the T. Rex and the tridactyl, and provide a guide for interpreting the effects of many different types of erosion on these invaluable impressions.

- MCA backs closure of Arctic waters
06-12-2007 · EurekAlert!
The Marine Conservation Alliance supports action today by the North Pacific Fishery Management Council to close all federal waters north of the Bering Strait to commercial fishing until a management plan, including habitat protection, is fully developed."Climate change is having a significant effect on the Arctic, opening previously ice-covered waters and drawing cold water species further north," said MCA's Dave Benton. "The council is right to look at closing these waters as a precautionary measure."
