Baby Milky Way Model Is Highest-Resolution-Ever Galaxy Sim

June 25, 2009 by rkaufman

How quickly they grow. First they're just a couple wisps of gas and next thing you know they're a galaxy 100,000 light years wide.

Cosmotologist Ben Moore at the University of Zurich in Switzerland has unearthed the Milky Way's baby pictures, so to speak, in a mathematical simulation that is the highest-resolution simulation ever produced of a galaxy's formation.

Ability to literally imagine oneself in another's shoes may be tied to empathy

New research from Vanderbilt University indicates the way our brain handles how we move through space -- including being able to imagine literally stepping into someone else's shoes -- may be related to how and why we experience empathy toward others.

Solar Research Team Heading to Europe for Experiments

A solar energy research team from Valparaiso University’s College of Engineering will return to Switzerland this summer to continue testing the potential of harnessing the sun’s energy for industrial applications. Valpo, a member of the Council on Undergraduate Research, has been pursuing the research project since 2006.

World's fastest and most sensitive astronomical camera

"The performance of this breakthrough camera is without an equivalent anywhere in the world. The camera will enable great leaps forward in many areas of the study of the Universe," says Norbert Hubin, head of the Adaptive Optics department at ESO. OCam will be part of the second-generation VLT instrument SPHERE.

IBEX spacecraft detects fast neutral hydrogen coming from the moon

NASA's Interstellar Boundary Explorer (IBEX) spacecraft has made the first observations of very fast hydrogen atoms coming from the moon, following decades of speculation and searching for their existence.

New findings encourage more vigilant monitoring of seizure activity among intensive care patients

NEW YORK (June 17, 2009) -- Two new studies published by neurologists at Columbia University Medical Center and NewYork-Presbyterian Hospital demonstrate a need for more vigilant monitoring for seizure activity among intensive care patients who may be experiencing subtle seizures that are typically unrecognized.

Meteorite grains divulge Earth's cosmic roots

The interstellar stuff that became incorporated into the planets and life on Earth has younger cosmic roots than theories predict, according to the University of Chicago postdoctoral scholar Philipp Heck and his international team
of colleagues.

Perforated surgical gloves associated with surgical site infection risk

Surgical gloves that develop holes or leaks during a procedure appear to increase the risk of infection at the surgical site among patients who are not given antibiotics beforehand, according to a report in the June issue of Archives of Surgery, one of the JAMA/Archives journals.

Meteorite Grains Divulge Earth's Cosmic Roots

The interstellar stuff that became incorporated into the planets and life on Earth has younger cosmic roots than theories predict, according to the University of Chicago postdoctoral scholar Philipp Heck and his international team of colleagues.

Heck and his colleagues examined 22 interstellar grains from the Murchison meteorite for their analysis.

Physicists Discuss the Science of 'Angels & Demons'

Soeren Prell admits to being amused by some of the high energy physics portrayed in “Angels & Demons,” the summer thriller starring science, religion and Tom Hanks.

Take, for example, scenes depicting CERN, the European Organization for Nuclear Research near Geneva, Switzerland, and its Large Hadron Collider, the $8 billion, 17-miles-around particle accelerator.

Manipulating light on a chip for quantum technologies

A team of physicists and engineers at Bristol University has demonstrated exquisite control of single particles of light -- photons -- on a silicon chip to make a major advance towards long-sought-after quantum technologies, including super-powerful quantum computers and ultra-precise measurements.

Stellar family in crowded, violent neighborhood proves to be surprisingly normal

The massive Arches Cluster is a rather peculiar star cluster. It is located 25 000 light-years away towards the constellation of Sagittarius (the Archer), and contains about a thousand young, massive stars, less than 2.5 million years old [1].

Enzyme involved in inflammatory bowel disease discovered at Penn State College of Medicine

Researchers at Penn State College of Medicine, working with biochemists, geneticists and clinicians at the University of Bern, Switzerland and in the United Kingdom, have discovered an enzyme that has a key role in inflammatory bowel disease (IBD).

MicroRNAs grease the cell's circadian clockwork

Most of our cells possess an internal clock, a group of genes displaying a cyclic expression pattern that reaches a peak once a day. A large number of circadian genes are expressed by organs such as the liver, whose activity needs to be precisely regulated over the course of the day.

Zebrafish provide a model for cancerous melanoma in humans

In a new study published in Disease Models & Mechanisms, scientists use the zebrafish to gain insight into the influence of known cancer genes on the development and progression of melanoma, an aggressive form of human skin cancer with limited treatment options.
