New observations by NASA's Cassini spacecraft indicate the rings of Saturn, once thought to have formed during the age of the dinosaurs, instead may have been created roughly 4.5 billion years ago when the solar system was still under construction.
According to the Bible, when Jesus was born three Magi saw a star in the East that signaled the birth of a new king. But just what was it, from an astronomical point of view, that the Magi actually saw?
Fred Grosse, a professor of physics and astronomy at Susquehanna University in Selinsgrove, Pa., says there are several popular theories that may answer this question.
“Astronomical objects or events which would be of interest to serious stargazers of the time include comets and meteors, nova or supernova, and auroras,” Grosse says.
Scientists funded by the Biotechnology and Biological Sciences Research Council (BBSRC) at Imperial College London have overcome two significant obstacles on the road to harnessing stem cells to build patches for damaged hearts.
LA JOLLA, CA — Like a circuit breaker that prevents electrical wiring from overheating and bringing down the house, a tiny family of three molecules stops the immune system from mounting an out-of-control, destructive inflammatory response against invading pathogens, researchers at the Salk Institute for Biological Studies have found.
Researchers at the University of Newcastle say a glass of wine a day may be of benefit to the health of older women.
It has been a decade since University of Washington scientists first pinpointed specific instances of air pollution, including Gobi Desert dust, traversing the Pacific Ocean and adding to the mix of atmospheric pollution already present along the West Coast of North America.
Now a UW researcher is finding that dust from the Gobi and Taklimakan deserts in China and Mongolia is routinely present in the air over the western United States during spring months.
Although there have been great improvements in the field of robotics in the last fifty years, much work remains in order to introduce androids into our daily life. Rafael Muñoz Salinas, a researcher from de Department of Computer Science and Artificial Intelligence of the University of Granada, is the author of a doctoral thesis which represents a major improvement in the interaction between robots and human beings.
Women are more likely to persist with using creams, supplements and plastic surgery to look younger if they feel these are not yet working, new research says.
A study of 297 women aged from 27 to 65 years found that they were more motivated to persist with special diets, vitamins, creams, Botox or plastic surgery if they believed these had so far failed to make them look significantly younger.
Vasopressin should be used with great caution for the treatment of hypotension in septic shock, according to results from an international research team published today in the online open access journal Critical Care. Their experiments - conducted in pigs - show it can significantly reduce blood flow to vital organs.
The peptide hormone vasopressin is being developed as a new therapy for the hemodynamic support of septic shock and vasodilatory shock due to systemic inflammatory response syndrome.
Domestic violence is an inherent problem in Turkey, and healthcare workers are doing little to combat the prevalence of wife beating, according to research published in the online open access journal, BMC Public Health. A survey of medical personnel reveals that a lack of training and a cultural acceptance of domestic violence may prevent victims from obtaining the support they desperately require.
