Fish oil fights weight loss due to chemotherapy
A new analysis has found that supplementing the diet with fish oil may prevent muscle and weight loss that commonly occurs in cancer patients who undergo chemotherapy. Published early online in Cancer, a peer-reviewed journal of the American Cancer ...
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...
Tool makes search for Martian life easier
RICHLAND, Wash. -- Finding life on Mars could get easier with a creative adaption to a common analytical tool that can be installed directly on the robotic arm of a space rover.
In a recent paper published online in the journal Planetary and S...
Species loss tied to ecosystem collapse and recovery
PROVIDENCE, R.I. [Brown University] -- The world's oceans are under siege. Conservation biologists regularly note the precipitous decline of key species, such as cod, bluefin tuna, swordfish and sharks. Lose enough of these top-line predators ...
What triggers mass extinctions? Study shows how invasive species stop new...
An influx of invasive species can stop the dominant natural process of new species formation and trigger mass extinction events, according to research results published today in the journal PLoS ONE.
The study of the collapse of Earth's marine...
When the black hole was born
Most galaxies in the universe, including our own Milky Way, harbor super-massive black holes varying in mass from about one million to about 10 billion times the size of our sun. To find them, astronomers look for the enormous amount of radiation em...
How often do giant black holes become hyperactive?
A new study from NASA's Chandra X-ray Observatory tells scientists how often the biggest black holes have been active over the last few billion years. This discovery clarifies how supermassive black holes grow and could have implications for ho...
Astronomers discover, image new planet in planetary system very similar to...
An international team of astronomers has discovered and imaged a fourth giant planet outside our solar system, a discovery that further strengthens the remarkable resemblances between a distant planetary system and our own.
The research is publi...
