Supersonic 'rain' falls on newborn star
08-29-2007 · EurekAlert!
Astronomers at the University of Rochester have discovered five Earth-oceans' worth of water that has recently fallen into the planet-forming region around an extremely young, developing star.Dan Watson of the University of Rochester believes he is the first to see a short-lived stage of protoplanetary disk formation, and the manner in which a planetary system’s supply of water arrives from the natal envelope within which its parent star originally formed.

Like humans, monkey see, monkey plan, monkey do
12-06-2007 · EurekAlert!
How many times a day do you grab objects such as a pencil or a cup? We perform these tasks without thinking, however the motor planning necessary to grasp an object is quite complex. For example, waiters will pick up an inverted glass with their thumb pointing down if they plan to pour water into the glass. Is this something that other animals, non-tool users, would do?

NASA images, White Sands features support a wetter Mars
12-07-2006 · EurekAlert!
NASA's announcement yesterday of evidence that water still flows on Mars, at least in brief spurts, demonstrates that the view of Mars as a very dry planet should be re-evaluated, says Dawn Sumner, professor of geology at UC Davis. Recent work from by Sumner and graduate student Greg Chavdarian also supports the presence of liquid water near the surface.

Research team uses satellite to track Earth's water
01-31-2007 · EurekAlert!
For the first time, a team of scientists from the University of Colorado and NASA has used a spaceborne instrument to track the origin and movements of water vapor throughout Earth's atmosphere, providing a new perspective on the dominant role Earth's water cycle plays in weather and climate.

Life-giving rocks from a depth of 250 km
09-26-2007 · EurekAlert!
If our planet did not have the ability to store oxygen in the deep reaches of its mantle there would probably be no life on its surface. This is the conclusion reached by scientists at the University of Bonn who have subjected the mineral majorite to close laboratory examination. Majorite performs an important function as an oxygen reservoir. Near the Earth's surface the mineral breaks down, releasing oxygen, which then binds with hydrogen from the Earth's interior to form water.

A galactic fossil
05-10-2007 · EurekAlert!
How old are the oldest stars? Using ESO's VLT, astronomers recently measured the age of a star located in our galaxy. The star, a real fossil, is found to be 13.2 billion years old, not very far from the 13.7 billion years age of the universe. The star, HE 1523-0901, was clearly born at the dawn of time.

New microsensor measures volatile organic compounds in water and air on-site
09-17-2007 · EurekAlert!
Researchers at the Georgia Institute of Technology have developed a miniature sensor that uses polymer membranes deposited on a tiny silicon disk to measure pollutants present in aqueous or gaseous environments. An array of these sensors with different surface coatings could be used during field-testing to rapidly detect many different chemicals.

Hubble yields direct proof of stellar sorting in a globular cluster
10-24-2006 · EurekAlert!
A seven-year study with the NASA/ESA Hubble Space Telescope has provided astronomers with the best observational evidence yet that globular clusters sort out stars according to their mass. Heavier stars slow down and sink to the cluster's core, while lighter stars pick up speed and move across the cluster to its periphery. This process, called "mass segregation," has long been suspected for globular star clusters, but has never before been directly seen in action.

Red dust in planet-forming disk may harbor precursors to life
01-03-2008 · EurekAlert!
Astronomers at the Carnegie Institution have found the first indications of highly complex organic molecules in the disk of red dust surrounding a distant star. The eight-million-year-old star, known as HR 4796A, is inferred to be in the late stages of planet formation, suggesting that the basic building blocks of life may be common in planetary systems.
