Two consecutive chaotic and dangerous landings by Soyuz space capsules, including one with an American astronaut aboard, have NASA and space experts concerned about the spacecraft's reliability in ferrying astronauts to and from the international space station.

NEW YORK -- The 300 Kihansi spray toads residing in a small room at the Bronx Zoo chirp cheerily as they bask in a light sprinkling of water 14 times a day. Until a few years ago, the tiny, mustard-colored toads existed only in a river gorge in Tanzania. Now the survivors are confined to the Bronx...

Los angeles (Reuters) - Iconic singer and songwriter Neil Young has had an honor bestowed upon him that is not received by many musicians -- his own spider.

Highlights from the May/June 2008 issue of Annals of Family Medicine, featuring articles that take a look inside the doctor-patient relationship from the patient's, as well as the physician's point of view.

Editor's Note: This story is a supplement to the Feature "The Chaotic Genesis of Planets" from the May 2008 issue of Scientific American.Meteorites are not just space rocks but space fossils--planetary scientists’ only tangible record of the origin of the solar system. Planetary scientists think that they come from asteroids, which are fragments of planetesimals that never went on to form planets and have remained in deep freeze ever since. The composition of meteorites reflects what must have happened on their parent bodies. Intriguingly, they bear the scars of Jupiter’s early gravitational effects. [More]

(American chemical Society) The American Chemical society's News Service Weekly PressPac contains reports from 36 major peer-reviewed journals on chemistry, health, medicine, energy, environment, food, nanotechnology and other hot topics.

NOAA scientists today released a 20-year study showing that environmental laws enacted in the 1970s are having a positive effect on reducing overall contaminant levels in coastal waters of the US. However, the report points to continuing concerns with elevated levels of metals and organic contaminants found near urban and industrial areas of the coasts.

More than 600 million years of evolution has taken two unlikely distant cousins -- turkeys and scallops -- down very different physical paths from a common ancestor. But University of Leeds researchers have found that a motor protein, myosin 2, remains structurally identical in both creatures.

Reducing the level of contamination of water is the aim of the line of research being undertaken by Dr. José Ignacio Lombraña at the University of the Basque Country's Faculty of science and Technology. He is investigating chemical treatment capable of eliminating contaminants dumped by industry, in order to reuse the waste water.
