XMM-Newton has been surprised by a rare type of galaxy, from which it has detected a higher number of X-rays than thought possible. The observation gives new insight into the powerful processes shaping galaxies during their formation and evolution.
Scientists working with XMM-Newton were looking into the furthest reaches of the universe, at celestial objects called quasars. These are vast cosmic engines that pump energy into their surroundings. It is thought an enormous black hole drives each quasar.
Its Ingrid Bells turn at bat. She steps up to the plate, awaiting the pitch. A 70-mph fastball soars toward her. She swings and connects with the ball.
Foul ball! Everyone cheers for her anyway.
esearchers have made a breakthrough in the development of "green gasoline," a liquid identical to standard gasoline yet created from sustainable biomass sources like switchgrass and poplar trees.
Cardiovascular diseases (CVD) are major contributors to morbidity and mortality worldwide. Several interacting environmental, biochemical, and genetic risk factors can increase disease susceptibility. While some of the genes involved in the etiology of CVD are known, many are yet to be discovered. During the last few decades, scientists have searched for these genes with genome-wide linkage and association methods, and with more targeted candidate gene studies.
Researchers obtain direct electrical control over a single electron spin.

Autobiographical notes written by the Lancashire inventor of the high speed diesel engine have been recovered from a garage in Manchester after lying forgotten for 25 years. University of Manchester historian Dr. Yaakov Wise -- who made the discovery -- says the Charles Chapman manuscript gives a unique insight into the 1932 "world beater."
Dr Wise, who worked at the legendary Perkins Engines where Chapman was based was given the document in 1983 - four years after the inventor died aged 82- but rediscovered it after clearing out a garage 25 years later.
Leaky blood vessels that lose their ability to protect the spinal cord from toxins may play a role in the development of amyotrophic lateral sclerosis, better known as ALS or Lou Gehrigs disease, according to research published in the April issue of Nature Neuroscience.
The relationship between a thin liquid film or drop of liquid and the shape of the surface that it wets is explained with a new simplified mathematical formula published this week in Physical Review Letters.
Understanding the precise interaction between liquids and surfaces is important for a number of areas, including the chemical industry and new nanotechnologies.

April 7 . . .A new study presented at the Experimental Biology Annual Meeting shows that a proprietary blend extracted from canola, Dermytol, produces a pronounced reduction of malignant melanoma cell growth. Dermytol, a proprietary compound developed by KGK Synergize Inc., a biotechnology company in Ontario Canada, is designed to protect skin cells from damage that may lead to skin cancer.
