The evolutionary tradeoff between becoming a bigger fighter or lover could lead to new species among dung beetle populations.
Male beetles may not transform in the blink of an eye, but natural selection seems to have driven rapid evolution in the size of their fighting horns - and their reproductive tools - during a time period […]

“The rover is back on flat ground,” said Paolo Belluta, engineer and rover driver at NASA’s Jet Propulsion Laboratory in Pasadena, Calif.

ESA’s (European Space Agency’s) formation-flying quartet of satellites, Cluster, has discovered that the Earth’s own magnetic field is causing the constant leak out of oxygen from its atmosphere into space.
The new work uses data collected by Cluster from 2001 to 2003.
During this time, Cluster amassed information about beams of electrically charged oxygen atoms, known as […]
ows can sense Earth’s magnetic field, scientists say.
German scientists using satellite images posted online by the Google Earth software programme have observed something that has escaped the notice of farmers, herders and hunters — Cattle grazing or at rest tend to orient their bodies in a north-south direction just like a compass needle, the Los […]
American space agency NASA’s newest observatory, the Gamma-Ray Large Area Space Telescope (GLAST), has begun its mission of exploring the universe in high-energy gamma rays.
Scientists expect GLAST, space agency’s next generation mission designed to explore the most energetic phenomena of universe, to discover many new pulsars, reveal powerful processes near super-massive black holes at the […]
A fifth of HIV patients are particularly vulnerable to brain damage like dementia and other disorders when the lethal virus manages to slip out of the bloodstream and cross into the brain.
Scientists at Albert Einstein College of Medicine have found strong evidence that a component of cell walls of intestinal bacteria - a chemical present […]
Glistening marble floors. Landscaped lawns. A golf course. This $1.5 million-a-pop housing development is one of the plushest yet in Gurgaon, a satellite city on New Delhi’s edge that has become an icon of booming India.
But 18 months after they went on sale, half the houses in the first phase of construction stand empty and […]

My friend says they are both the same, as a fan circulates the air fast therefore the air particles cool down and become cold and give you cold air. And the air conditioner pratically does the same thing. Is this right?
A fan does not change the condition of the air (cooling it, etc.). […]
I take regular exercise. But tired at the end of the day.
Going out to feed the goat in the evening after dark, and finding the gate standing open, and the entire herd of over 100 animals vanished.
Not knowing the neighbors West Highland bull was loose, and walking between him and his cows.
