Stars found far from galaxy center - Nasa

The newfound young star clusters lie thousands of light-years below the plane of our Milky Way galaxy, a flat spiral disk seen in this artist's conception. If alien lifeforms were to develop on planets orbiting these stars, they would have views of a portion, or all, of the galactic disk.

Beliefs can regulate effects of nicotine on the human brain

Two identical cigarettes led to a new discovery. Study participants inhaled nicotine, yet they showed significantly different brain activity. Why the difference? Some subjects were told their cigarettes were nicotine free. Credit: © Nomad_Soul / Fotolia Two identical cigarettes led to a discovery by scientists at the Virginia Tech Carilion Research Institute. Study participants inhaled nicotin

Genetically speaking, mammals are more like their fathers

Newborn baby and his father's hand. Specifically, the research shows that although we inherit equal amounts of genetic mutations from our parents -- the mutations that make us who we are and not some other person -- we actually "use" more of the DNA that we inherit from our dads.

Old-looking galaxy in a young universe: Astronomers find dust in the early universe

This spectacular view from the NASA/ESA Hubble Space Telescope shows the rich galaxy cluster Abell 1689. The huge concentration of mass bends light coming from more distant objects and can increase their total apparent brightness and make them visible. One such object, A1689-zD1, is located in the box -- although it is still so faint that it is barely seen in this picture. New observations wit

Newborn neurons in adult brain may help us adapt to environment

Neurons . "New neurons may serve as a means to fine-tune the hippocampus to the predicted environment," Opendak says. "In particular, seeking out rewarding experiences or avoiding stressful experiences may help each individual optimize his or her own brain. Credit: © ktsdesign / Fotolia The discovery that the human brain continues to produce new neurons in adulthood challenged a major dogma in

Is not there Big Bang ? A quantum equation show that the universe has no beginning

The universe could have existed forever, according to a new model that applies quantum correction terms to complement the theory of general relativity of Einstein. The model can also explain dark matter and dark energy. The widely accepted age of the universe, according to estimates of general relativity, is 13,800 million years. At first, everything was dealt a single infinitely dense poin

The Technion Researchers Find to NanoParticles may Threaten Heart

Nanoparticles, extremely tiny particles measured in billionths of a meter, are increasingly everywhere, and especially in biomedical products. Their toxicity has been researched in general terms, but now a team of Israeli scientists has for the first time found that exposure nanoparticles (NPs) of silicon dioxide (SiO2) can play a major role in the development of cardiovascular diseases when t

From Pig to Fuel - Anaerobic digester generates energy, reduces odors

 Teng Lim is operating a small-scale anaerobic digester at the MU swine farm in Columbia. The system generates energy and can mitigate hog odor. Courtesy Jon Lamb. The University of Missouri has unveiled a prototype small-scale anaerobic digestion system that produces biogas from pig manure. The biogas can be used to heat a farm and create electricity. The device also reduces odor from

A Long dry spell doomed Mexican city 1,000 years ago

Ruins of the city of Cantona in the Mexican state of Puebla, with the mountain Cerro Pizarro in the background. The city was abandoned almost 1,000 years ago, probably as a result of a prolonged dry spell. (Ines Urdaneta image courtesy of Wikimedia Commons.) A UC Berkeley study sheds new light on this question, providing evidence that a prolonged period of below-average rainfall was partly re
