Dwarf galaxies need dark matter too, U-M astronomers say
Stars in dwarf spheroidal galaxies behave in a way that suggests the galaxies are utterly dominated by dark matter, University of Michigan astronomers have found. view more (2007-10-25)
The inside dope
Often, things can be improved by a little 'contamination.' Steel, for example is iron with a bit of carbon mixed in. To produce materials for modern electronics, small amounts of impurities are introduced into silicon - a process called doping. view more (2007-07-27)
Study sheds new light on early star formation in the universe
A groundbreaking study has provided new insight into the way the first stars were formed at the start of the Universe, some 13 billion years ago. view more (2007-09-14)
UCI scientists discover minimum mass for galaxies
By analyzing light from small, faint galaxies that orbit the Milky Way, UC Irvine scientists believe they have discovered the minimum mass for galaxies in the universe - 10 million times the mass of the sun. view more (2008-08-28)
More biogas, less sludge
Germany has more than 10,000 sewage plants, using costly processes to treat household, industrial and restaurant waste water. The treated water is discharged back into river and lake systems. What remains is an organic / inorganic mixture of sludge. The issue is how to dispose of this residue. Up to now, sewage sludge has been used as an... view more... (2002-11-14)
NMSU/Wake Forest solar breakthrough will help spur viability of alternative energy
Imagine being able to paint your roof with enough alternative energy to heat and cool your home. What if soldiers in the field could carry an energy source in a roll of plastic wrap in their backpacks? view more (2005-10-10)
Breakthrough: UNC scientists have created world's tiniest uniform, precisely shaped organic particles
University of North Carolina at Chapel Hill chemists have developed what they believe is a breakthrough method of creating the world's tiniest manufactured particles for delivering drugs and other organic materials into the human body. view more (2005-06-22)
ORNL, Los Alamos pioneer new approach to assist scientists, farmers
Sustainable farming, initially adopted to preserve soil quality for future generations, may also play a role in maintaining a healthy climate, according to researchers at the Department of Energy's Oak Ridge and Los Alamos national laboratories. view more (2009-11-20)
Flexible electronics advance boosts performance, manufacturing
Flexible electronics made with organic, or carbon-based, transistors could enable technologies such as low-cost sensors on product packaging and ''electronic paper'' displays as thin and floppy as a placemat. view more (2006-12-14)
Surprising results in teen study: adolescent risky behavior may signal mature brain
A new study using brain imaging to study teen behavior indicates that adolescents who engage in dangerous activities have frontal white matter tracts that are more adult in form than their more conservative peers. view more (2009-08-26)
New system for storing lithium-polymer energy
The basque technology centre CIDETEC is working on a project about lithium-polymer energy with the collaboration of the companies CEGASA and ZIGOR. view more (2002-09-09)
The Amazon : wedding in white and black
What happens when two rivers of widely different character meet? In order to answer this question, hydrologists from IRD (Institut de recherché pour le développement) have examined the confluence of the Rivers Negro and Solim'µes, in Brazil. These two large water courses join just downstream from Manaus to form the Amazon. Up to now,... view more... (2000-11-07)
Billions of particles of anti-matter created in laboratory
ake a gold sample the size of the head of a push pin, shoot a laser through it, and suddenly more than 100 billion particles of anti-matter appear. The anti-matter, also known as positrons, shoots out of the target in a cone-shaped plasma "jet." view more (2008-11-18)
Oldest complex organic molecules found in ancient fossils
Ohio State University geologists have isolated complex organic molecules from 350-million-year-old fossil sea creatures - the oldest such molecules yet found. view more (2006-10-26)
Classic experiments give new insight on life's origin
The building blocks of life may have emerged in volcanic eruptions on the early Earth, according to a new analysis of classic experiments performed more than fifty years ago. view more (2008-10-17)
Manufactured Buckyballs don't harm microbes that clean the environment
Even large amounts of manufactured nanoparticles, also known as Buckyballs, don't faze microscopic organisms that are charged with cleaning up the environment, according to Purdue University researchers. view more (2008-04-09)
Cowpeas could add sustainability to cropping systems
Ground left fallow in the High Plains to store soil moisture between crops may be better off with a legume crop such as cowpeas, according to a Texas Agricultural Experiment Station researcher. view more (2005-10-13)
Deep-sea species' loss could lead to oceans' collapse, study suggests
The loss of deep-sea species poses a severe threat to the future of the oceans, suggests a new report publishing early online on December 27th and in the January 8th issue of Current Biology, a publication of Cell Press. view more (2007-12-28)
Uncharged organic molecule can bind negatively charged ions
Indiana University Bloomington chemists have designed an organic molecule that binds negatively charged ions, a feat they hope will lead to the development of a whole new molecular toolbox for biologists, chemists and medical researchers who want to remove chlorine, fluorine and other negatively charged ions from their solutions. view more (2008-02-27)
Frozen lightning: NIST's new nanoelectronic switch
Researchers at the National Institute of Standards and Technology (NIST) have demonstrated a prototype nanoscale electronic switch that works like lightning—except for the speed. view more (2007-03-05)
