Supermassive black holes with the mass of many millions of stars have been detected at the centre of many large galaxies. A super-massive black hole acts like a lurking "monster" at the center of the galaxy which swallows the surrounding material through the intensity of its gravitational pull. X-ray observations indicate that a large amount of energy is produced by the in-fall of matter into a black hole, and ejected in powerful jets. Astronomers from the Max Planck Institute for Extraterrestrial Physics have now shown that these jets eject matter not only from their host galaxies but even the gas between the galaxy group members.

Massive stars end their lives in gigantic explosions, so called supernovae, and can become - for a short time - brighter than a whole galaxy, which is made up of billions of stars. Although supernovae have been studied theoretically by computer models for several decades, the physical processes happening during these blasts are so complex that until now astrophysicists could only simulate parts of the process and so far only in one or two dimensions. Researches at the Max Planck Institute for Astrophysics in Garching have now carried out the first fully three-dimensional computer simulations of a core collapse supernova over a timescale of hours after the initiation of the blast. They thus could answer the question of how initial asymmetries, which emerge deep in the dense core during the very early stages of the explosion, fold themselves into inhomogeneities observable during the supernova blast.

The 2010 Space Propulsion Congress brought together some 500 international experts in aerospace propulsion systems in the Basque city of Donostia-San Sebastián. The latest technological advances were made known, including those that will make reaching Mars possible in the future as well as other planets such as Mercury.

Washington, D.C.—Tiny variations in the isotopic composition of silver in meteorites and Earth rocks are helping scientists put together a timetable of how our planet was assembled beginning 4.568 billion years ago. The new study, published in the journal Science, indicates that water and other key volatiles may have been present in at least some of Earth's original building blocks, rather than acquired later from comets, as some scientists have suggested.

Pasadena, CA—A team of astronomers including Ivelina Momcheva of the Carnegie Observatories has discovered the most distant cluster of galaxies ever found. In a surprising twist, the young cluster born just 2.8 billion years after the Big Bang appears remarkably similar to the much older present-day galaxy clusters.

Numerous studies have documented the favorable effects of MARS albumin dialysis treatment on clinical and laboratory parameters and survival in liver failure patients. However, to ensure that limited resources are utilized in an ethical manner, the subjective feelings of the patient in terms of health-related quality of life and costs should also be taken into account. So far, only a few small non-randomized studies have focused on the cost-utility and the health-related quality of life of MARS-treated acute-on-chronic liver failure patients. Currently, there are no studies on the health-related quality or cost-utility of MARS treatment in acute liver failure (ALF).

Regular exercise can play an important a role in improving the physical and mental wellbeing of individuals with schizophrenia, according to a review published in The Cochrane Library. Following a systematic review of the most up-to-date research on exercise in schizophrenia, researchers concluded that the current guidelines for exercise should be followed by people with schizophrenia just as they should by the general population.
