Distant black holes may be source of high-energy cosmic rays
Breakthrough astrophysics research may have established the hitherto mysterious source of exceptionally high-energy cosmic ray emissions, according to recently published research that culminates a project developed by a scientist at the U.S. Department of Energy's (DOE) Argonne National Laboratory.   view more (2007-11-12)

Auger Observatory links highest-energy cosmic rays with violent black holes
Scientists of the Pierre Auger Collaboration, which includes New York University Physics Professor Glennys R. Farrar, have concluded that active galactic nuclei are the most likely candidate for the source of the highest-energy cosmic rays that hit Earth.   view more (2007-11-09)

Brains of term infants with heart disease resemble those of preemies
The brains of full-term infants with congenital heart disease appear more similar to those of premature newborns than to the brains of normal term infants, a study conducted by researchers at UCSF has found.   view more (2007-11-08)

Further evidence that genetics has a role in determining sexual orientation in men
Is sexual orientation something people are born with - like the colour of their skin and eyes - or a matter of choice"   view more (2007-11-08)

Rutgers physicists show how electrons 'gain weight' in metal compounds near absolute zero
Rutgers University physicists have performed computer simulations that show how electrons become one thousand times more massive in certain metal compounds when cooled to temperatures near absolute zero - the point where all motion ceases.   view more (2007-11-02)

High-tech textiles pave the way for glowing garments
Researchers at The University of Manchester have developed high-tech battery-powered textile yarns that can be used to make clothing glow in the dark.   view more (2007-10-29)

Imaging shows structural changes in mild traumatic brain injury
Researchers report that diffusion tensor imaging can identify structural changes in the white matter of the brain that correlates to cognitive deficits even in patients with mild traumatic brain injury.   view more (2007-10-26)

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)

Social stress + darkness = increased anxiety
Just in time for Halloween, researchers are releasing new data that show darkness increases the impact of social stress, in an article scheduled for publication in the November 15th issue of Biological Psychiatry. As children and adults alike gear up for the anticipation and excitement of this... view more (2007-10-23)

Biggest 'small' black hole discovered
Discovery of the largest example of a "small" black hole - one formed from the collapse of a single massive star at the end of its lifetime - has led scientists to revaluate of how black holes come into being, according to a report in Nature.   view more (2007-10-22)

Exposure to sunlight may decrease risk of advanced breast cancer by half
A research team from the Northern California Cancer Center, the University of Southern California, and Wake Forest University School of Medicine has found that increased exposure to sunlight - which increases levels of vitamin D in the body -- may decrease the risk of advanced breast cancer.   view more (2007-10-19)

Genetic contributions to human brain morphology and intelligence
While showing an impressive growth prenatally, the human brain is not completed at birth. There is considerable brain growth during childhood with dynamic changes taking place in the human brain throughout life, probably for adaptation to our environments.   view more (2007-10-17)

Fish get insomnia, eyes wide open, say Stanford sleep researchers
Scientists at the Stanford University School of Medicine have hooked a fish that suffers from insomnia in their quest to understand the genetics behind sleep disorders.   view more (2007-10-16)

Testosterone turns male juncos into blustery hunks -- and bad dads
The ability to ramp up testosterone production appears to drive male dark-eyed juncos to find and win mates, but it comes with an evolutionary cost. Big fluctuations in testosterone may also cause males to lose interest in parenting their own young, scientists have learned.   view more (2007-10-16)

MS that Runs in Families Appears More Severe than Non-Familial MS
Magnetic resonance images (MRI) of a large group of patients with multiple sclerosis has provided the first evidence that those with a history of MS in their families show more severe brain damage than patients who have no close relatives with the disease.   view more (2007-10-12)

Cassini on the trail of a runaway mystery
Scientists are on the trail of Iapetus' mysterious dark side, which seems to be home to a bizarre 'runaway' process that is transporting vaporised water ice from the dark areas to the white areas of the Saturnian moon.   view more (2007-10-10)

Negativity is contagious, study finds
Though we may not care to admit it, what other people think about something can affect what we think about it. This is how critics become influential and why our parents' opinions about our life choices continue to matter, long after we've moved out.   view more (2007-10-05)

FSU physicist shining a light on mysterious 'dark matter'
We've all been taught that our bodies, the Earth, and in fact all matter in the universe is composed of tiny building blocks called atoms. Now imagine if this weren't the case.   view more (2007-10-03)

The dark matter of the universe has a long lifetime
New research from the Niels Bohr Institute presents new information that adds another piece of knowledge to the jigsaw puzzle of the dark mystery of the universe - dark matter. The research has just been published in the scientific journal Physical Review Letters.   view more (2007-10-02)

New particles get a mass boost
A sophisticated, new analysis has revealed that the next frontier in particle physics is farther away than once thought. New forms of matter not predicted by the Standard Model of particle physics are most likely twice as massive as theorists had previously calculated, according to a just-published... view more (2007-10-02)

Study shows how the zebrafish gets his stripe
Scientists have discovered how the zebrafish (Danio rerio) develops one of its four stripes of pigment cells.   view more (2007-09-26)

A research warns that Human Papillomavirus, a sexually transmitted disease, might cause bladder cancer
DIGITAL The Human Papillomavirus (HPV) is considered the cause of one of the most important sexually transmitted diseases nowadays, and affects both men and women.   view more (2007-09-26)

Extraterrestrial Impact Likely Source of Sudden Ice Age Extinctions
At the end of the Pleistocene era, wooly mammoths roamed North America along with a cast of fantastic creatures - giant sloths, saber-toothed cats, camels, lions, tapirs and the incredible teratorn, a condor with a 16-foot wingspan.   view more (2007-09-25)

Landfill mining reduces environmental impact of growing waste
Retrieving material for composting from open dumps across the developing world could reduce the environmental impact of growing mountains of waste, according to researchers in India, writing today in the Inderscience publication, International Journal of Environmental Technology and Management.   view more (2007-09-19)
