SMART-1 – first European Lunar Adventure begins

This is clearly Europe´s time for interplanetary exploration. Having sent the first European mission to Mars, ESA is about to launch its first probe to the Moon. It is called SMART-1 and its goals are both technological and scientific. It is the first of a series of “Small Missions for Advanced Research in Technology”.

On the one hand, SMART-1 will test new state-of-the art instruments and techniques essential to ambitious future interplanetary missions, such as a solar-electric prim

Search for life could include planets, stars unlike ours

The search for life on other planets could soon extend to solar systems that are very different from our own, according to a new study by an Ohio State University astronomer and his colleagues.

In fact, finding a terrestrial planet in such a solar system would offer unique scientific opportunities to test evolution, said Andrew Gould, professor of astronomy here. In a recent issue of Astrophysical Journal Letters, he and his coauthors calculated that NASA’s upcoming Space Interferome

Jaws of clamworm are hardened by zinc

Scientists often look to nature for inspiration in the search for ways to make new materials. A new study of the clamworm, an intertidal creature, shows that it has jaws made partly of zinc, making them strong, stiff and tough –– fundamental properties by which all materials are evaluated.

The properties of the clamworm jaws are described in this week´s online publication of the Proceedings of the National Academies of Sciences (PNAS). The research began with questions by scientists a

Protein: Getting to the Meat of this essential Element

Living organisms operate with a variety of tens of thousands of protein structures and, though much research has been done on individual protein systems, little is understood about how different protein systems interact. Now an effort at Texas A&M University is bringing together all known information in an extensive, searchable internet site called Binding Interface Database.

“No one understands the rules of protein interaction,” said Dr. Jerry Tsai, Texas Agricultural Experiment Stat

World’s largest astronomical CCD camera installed on Palomar Observatory telescope

The world’s largest astronomical camera has been installed on Palomar Observatory’s 48-inch Oschin Telescope in California. This telescope has been working to improve our understanding of the universe for nearly 55 years. The new upgrade will help it to push the limits of the unknown for years to come.

The new camera is known as QUEST (Quasar Equatorial Survey Team). Designed and built by astrophysicists at Indiana and Yale universities, QUEST recently “saw” its first starlight and i

Safe is sexy

Females prefer burrows

The signal is an arched wall of sand called a hood which courting males of the fiddler crab Uca musica build at the entrances to their burrows on sand flats in Panama. Males have one very large claw that they wave to attract females to their burrows and females visit several males before choosing a mate by staying with a male in his burrow. These small crabs are at great risk of predation from ever-present shore birds. When moving between burrows they reduce th
