Gas rich galaxies confirm prediction of modified gravity theory
COLLEGE PARK, Md. -- Recent data for gas rich galaxies precisely match predictions of a modified theory of gravity know as MOND according to a new analysis by University of Maryland Astronomy Professor Stacy McGaugh. This -- the latest of severa...
Herschel finds less dark matter but more stars
ESA's Herschel space observatory has discovered a population of dust-enshrouded galaxies that do not need as much dark matter as previously thought to collect gas and burst into star formation.
The galaxies are far away and each boasts some 30...
Understanding patterns of seafloor biomass
Analysis of a comprehensive database has revealed strong links between biological productivity in the surface oceans and patterns of biomass and abundance at the seafloor, helping to explain large regional differences. The research was conducted...
Air pollutants from fireplaces and wood-burning stoves raise health concerns
WASHINGTON, Feb. 5, 2011 -- With millions of people warding off winter's chill with blazing fireplaces and wood-burning stoves, scientists are raising red flags about the potential health effects of the smoke released from burning wood. Their stud...
Natural dissolved organic matter plays dual role in cycling of mercury
Nature has a bit of a Jekyll and Hyde relationship with mercury, but researchers at the Department of Energy's Oak Ridge National Laboratory have made a discovery that ultimately could help explain the split personality.
While scientists have know...
College students lack scientific literacy, study finds
Most college students in the United States do not grasp the scientific basis of the carbon cycle – an essential skill in understanding the...
Identity parade clears cosmic collisions of the suspicion of promoting black...
10-Dec 2010 What happens when galaxies crash together? For years, these cosmic collisions have been blamed for triggering violent outbursts at the hearts of galaxies. Now, a remarkable piece of detective work has given a verdict: galactic mergers do...
Neuronal migration errors: Right cells, wrong place
Philadelphia, PA, 4 January 2011 - Normally, cortical nerve cells or neurons reside in the brain's gray matter with only a few scattered neurons in the white matter, but some people with schizophrenia have a higher number of neurons in the white mat...
Life thrives in porous rock deep beneath the seafloor, scientists say
SANTA CRUZ, CA--Researchers have found compelling evidence for an extensive biological community living in porous rock deep beneath the seafloor. The microbes in this hidden world appear to be an important source of dissolved organic matter in dee...
Dark matter could transfer energy in the Sun
Researchers from the Institute for Corpuscular Physics (IFIC) and other European groups have studied the effects of the presence of dark matter in the Sun. According to their calculations, low mass dark matter particles could be transferring ene...
