Scientists have found that calcium, aluminum-rich inclusions (CAIs), some of the oldest objects in the solar system, formed far away from our sun and then later fell back into the mid-plane of the solar system.The findings may lead to a greater understanding of how our solar system and possibly other solar systems formed and evolved.CAIs, roughly millimeter- to centimeter in size, are believed to have formed very early in the evolution of the solar system and had contact with nebular gas,...

By Anne M Stark, LLNL Using seawater and calcium to remove carbon dioxide (CO2) in a natural gas power plant's flue stream, and then pumping the resulting calcium bicarbonate in the sea, could be beneficial to the oceans' marine life. Greg Rau, a senior scientist with the Institute of Marine Sciences at UC Santa Cruz and who also works in the Carbon Management Program at Lawrence Livermore National Laboratory, conducted a series of lab-scale experiments to find out if a seawater/mineral...

By Diana Lutz, Washington University in St. Louis Experiments show that drilling mud that behaved more like quicksand and less like ketchup might have prevented the top-kill blowout On May 25th, 2010, the online arm of Upstream, a newspaper for the international oil and gas industry, reported that British Petroleum had started top-kill procedures on the Macondo well in the Gulf of Mexico. "The company said that the operation, which will pump heavy mud down the wellbore in an attempt to gain...

NRC Herzberg Institute of Astrophysics releases image of fourth planet orbiting bright star HR 8799 An international team of astronomers has discovered a fourth giant planet, HR 8799e, outside our solar system. The new planet joins the three planets that were the subjects of the first-ever images of a planetary family orbiting a star other than our Sun. The planets orbit the star HR 8799, which lies about 129 light years from Earth and is faintly visible to the naked eye. The international...

News from the 52nd annual meeting of the APS Division of Plasma Physics Physicists working on the National Spherical Torus Experiment (NSTX) at the Princeton Plasma Physics Laboratory are now one step closer to solving one of the grand challenges of magnetic fusion research"”how to reduce the effect that the hot plasma has on fusion machine walls (or how to tame the plasma-material interface). Some heat from the hot plasma core of a fusion energy device escapes the plasma and can...

Anne M Stark, Lawrence Livermore National Laboratory Beta cells, which make insulin in the human body, do not replicate after the age of 30, indicating that clinicians may be closer to better treating diabetes. Type 1 diabetes is caused by a loss of beta cells by auto-immunity while type 2 is due to a relative insufficiency of beta cells. Whether beta cells replicate after birth has remained an open issue, and is critically important for designing therapies for diabetes. By using radioactive...

Massive Compact Halo Object (MACHO) -- Massive compact halo objects, or MACHOs, are a type of astronomical body proposed as one possible explanation for the presence of dark matter in galactic halos. A MACHO is a small chunk of normal baryonic matter, far smaller than a star, which drifts through interstellar space unassociated with any solar system. Since MACHOs would not emit any light of their own, they would be very hard to detect. Recent work has suggested that MACHOs are not...
