Supermassive black holes, notorious for ripping apart and swallowing stars, might also help seed interstellar space with the elements necessary for life, such as hydrogen, carbon, oxygen and iron, scientists say.
Using NASAs Chandra X-ray Observatory and ESAs XMM-Newton satellite, scientists at Penn State University and the Massachusetts Institute of Technology found evidence of high-speed winds blowing away copious amounts of gas from the cores of two quasar galaxies, which are
Intelligent environment learns and is technically interactive
VTT, Technical Research Centre of Finland, has developed technology which operates through people’s gestures. The new concept is currently being introduced for research purposes at Italdesign-Giugiaro S. p.a. the Italian car design firm. The same technology is used in wireless terminal equipment user interface research in the Netherlands at the Philips research centre HomeLab.
This VTT technology known as gesture inter
A bacteriums ability to change its hairstyle may help in the effort to clean contaminated groundwater for drinking, according to Penn State researchers.
People are continually moving into places that are hot, sunny and arid where drinking water is in short supply, says R. Kramer Campen, Penn State graduate student in geosciences. “The imperative to find ways to clean groundwater is paramount,” he told attendees today (March 25) at the 225th American Chemical Society national meeting i
Intricate patterns formed by granular materials under the influence of electrostatic fields have scientists at the U.S. Department of Energys Argonne National Laboratory dreaming of new ways to create smaller structures for nanotechnologies. With a combination of electric fields and fluid mixtures, researchers Igor Aronson, Maksim Sapozhnikov, Yuri Tolmachev and Wai Kwok can cause tiny spheres of bronze and other metals to self-assemble into crystalline patterns, honeycombs, pulsating rings and
A procedure known as lung-volume reduction surgery (LVRS) appears to improve overall health and quality of life for individuals with end-stage emphysema, and these effects last as long as five years in more than half of this population, according to researchers at Washington University School of Medicine in St. Louis.
The findings appear in the March issue of the Journal of Thoracic and Cardiovascular Surgery. The procedure was developed at the School of Medicine in 1993 by the studys
A fast and ingenious new way to detect toxic contamination of water has been developed by researchers at the Hebrew University of Jerusalem.
The method, currently undergoing further experimentation and development, has particular consequences for countering bioterrorism, but with less ominous, potential implications as well for medical technologies, pharmaceuticals and industry, plus environmental quality in general.
The work of the research team, headed by Prof. Shimshon Belkin,
