A new chemical analysis of lunar material collected by Apollo astronauts in the 1970s conflicts with the widely held theory that a giant collision between Earth and a Mars-sized object gave birth to the moon 4.5 billion years ago. In the giant-collision scenario, computer simulations suggest that the moon had two parents: Earth and a hypothetical planetary body that scientists call "Theia." But a comparative analysis of titanium from the moon, Earth and meteorites, published by Junjun Zhang, graduate student in geophysical sciences at the University of Chicago, and four ...

A new X-ray study of the remains of an exploded star indicates that the supernova that disrupted the massive star may have turned it inside out in the process. Using very long observations of Cassiopeia A (or Cas A), a team of scientists has mapped the distribution elements in the supernova remnant in unprecedented detail. This information shows where the different layers of the pre-supernova star are located three hundred years after the explosion, and provides insight into the nature of the supernova. An artist's illustration on the left shows a simplified picture ...

WASHINGTON — Simultaneously attaining a reliable water supply for California and protecting and rehabilitating its Bay-Delta ecosystem cannot be realized until better planning can identify how trade-offs between these two goals will be managed when water is limited, says a new report from the National Research Council. Recent efforts have been ineffective in meeting these goals because management is distributed among many agencies and organizations, which hinders development and implementation of an integrated, comprehensive plan. Additionally, it is impossible to restore ...

Patients with inflammatory bowel disease (IBD) and other gastrointestinal (GI) disorders may be exposed to significant doses of diagnostic radiation, according to a new study in Clinical Gastroenterology and Hepatology, the official journal of the American Gastroenterological Association. "Our results show that significant increases in radiation exposure in the last decade have paralleled the increased use of computed tomography imaging," said Alan N. Desmond, MB, BMedSc, MRCPI, of the Cork University Hospital, Ireland, and lead author of this study. "While cumulative ...

An international team that includes University of British Columbia physicists has used ultra-fast laser pulses to identify the microscopic interactions that drive high-temperature superconductivity. In the experiment, to be outlined this Friday in the journal Science, electrons in a prototypical copper-oxide superconductor were excited by extremely short 100-femtosecond (0.0000000000001-second) laser pulses. As the material's electrons relax back to an equilibrium state, they release their excess energy via deformation of the superconductor's atomic lattice (phonons) ...

Physicists at the University of California, San Diego have discovered patterns which underlie the properties of a new state of matter. In a paper published in the March 29 issue of the journal Nature, the scientists describe the emergence of "spontaneous coherence," "spin textures" and "phase singularities" when excitons—the bound pairs of electrons and holes that determine the optical properties of semiconductors and enable them to function as novel optoelectronic devices—are cooled to near absolute zero. This cooling leads to the spontaneous production of a new coherent ...

Conventional wisdom tells us that in the business world, "you are who you know" — your social background and professional networks outweigh talent when it comes to career success. But according to a Tel Aviv University researcher, making the right connection only gets your foot in the door. Your future success is entirely up to you, says Prof. Yoav Ganzach of TAU's Recanati School of Management. When intelligence and socio-economic background (SEB) are pitted directly against one another, intelligence is a more accurate predictor of future career success, he asserts. ...

Idan Ginsburg, a graduate student in Dartmouth's Department of Physics and Astronomy, studies some of the fastest moving objects in the cosmos. When stars and their orbiting plants wander too close to the supermassive black hole at the center of the Milky Way, their encounter with the black hole's gravitational force can either capture them or eject them from the galaxy, like a slingshot, at millions of miles per hour. Although their origin remains a mystery and although they are invisible, black holes found at galaxy centers make their presence known through the effects ...

Greater lifetime exposure to the stress of traumatic events was linked to higher levels of inflammation in a study of almost 1,000 patients with cardiovascular disease led by researchers at the San Francisco VA Medical Center and the University of California, San Francisco. In the first study to examine the relationship between cumulative traumatic stress exposure and inflammation, the scientists found that the more traumatic stress a patient was exposed to over the course of a lifetime, the greater the chances the patient would have elevated levels of inflammatory markers ...

Some people like company. Others prefer to be alone. The same holds true for the particles that constitute the matter around us: Some, called bosons, like to act in unison with others. Others, called fermions, have a mind of their own. Different as they are, both species can show "collective" behavior -- an effect similar to the wave at a baseball game, where all spectators carry out the same motion regardless of whether they like each other. Scientists generally believed that such collective behavior, while commonplace for bosons, only appeared in fermions moving in ...
