- 28 new planets, 7 new brown dwarfs reported by California, Carnegie team
05-28-2007 · EurekAlert!
The combined California and Carnegie Planet Search team and Anglo-Australian Planet Search team announced at this week's American Astronomical Society meeting the discovery of 28 new planets outside our solar system, a 12 percent increase in the number of known exoplanets. The bounty of new planets, not to mention seven new brown dwarfs, allows the astronomers to draw conclusions about how planets form and how planet systems evolve.

- Astronomers discover scaled-down Jupiter and Saturn in a faraway solar system like our own
02-14-2008 · EurekAlert!
An international team of astronomers has discovered two planets that resemble smaller versions of Jupiter and Saturn in a solar system nearly 5,000 light years away. The find suggests that our galaxy hosts many planetary systems like our own, said Scott Gaudi, assistant professor of astronomy at Ohio State University.

- New Delft material concept for aircraft wings could save billions
09-26-2007 · EurekAlert!
Building aircraft wings with a special aluminium fiber combination makes them nearly immune to metal fatigue. The application of this technology, partly developed at Delft University of Technology, will lead to substantial savings. The unusual qualities of this special material can make a significant contribution to the development of truly energy-efficient, 'green' aircraft. Lower fuel consumption and reduction of maintenance costs could lead to worldwide savings as high as $100 billion.

- A newly discovered solar system contains scaled-down versions of Saturn and Jupiter
02-14-2008 · EurekAlert!
A team of international astronomers reports in the Feb. 15 issue of Science the discovery of a solar system nearly 5,000 light years away with scaled-down versions of Jupiter and Saturn. Their findings suggest our galaxy could conceivably contain many star systems similar to our own. NSF sponsored the research.

- Something new under the Sun
01-30-2007 · EurekAlert!
That plants grow better if grown in a greenhouse in the correct climate is nothing new. Dutch researcher Rachel van Ooteghem has designed a control system for an improved solar greenhouse that yields more. In the new greenhouse, good climate control with sustainable energy resulted not only in an increased crop yield but also a lower gas bill.

- Study: Long legs are more efficient
03-12-2007 · EurekAlert!
Scientists have known for years that the energy cost of walking and running is related primarily to the work done by muscles to lift and move the limbs.But how much energy does it actually take to get around? Does having longer legs really make a difference?Herman Pontzer, Ph.D., assistant professor of physical anthropology in Arts & Sciences, has developed a mathematical model for calculating energy costs for two and four-legged animals.

- Planning made easier: MU engineers develop software solution for complex space missions
12-03-2007 · EurekAlert!
Sending an unmanned spacecraft to the outer fringes of the solar system requires extensive planning. At the University of Missouri, engineers have developed an efficient and highly sophisticated mathematical algorithm (implemented as software) that determines the most efficient path for a spacecraft's journey from point A to point B -- no matter how many worlds or years away.
