Missing link in human evolution

Scientists have discovered a 47-million-year-old fossil which could provide the missing link between animals and humans.
The skeleton was discovered 26 years ago in Germany and lost in museums, until a paleontologist realized that it could be the missing link in human evolution chain.
Methane May Point to Life on Mars

Discovery of the gas raises the specter of Martian life
If you roll out of bed and see the headline "Life on Mars," is it because: a) it's a hoax, b) NASA got lucky, c) scientific genius won out, or d) it is written in a British tabloid?
The British Sun received a slap on the wrist from the journal Science, but news sites buzzed cautiously over a new NASA study about methane gas detected on Mars in 2003. Methane plumes traced to three specific regions could signal active geological processes—or possibly even gas-emitting microbes, said scientists during yesterday's press conference.
Is God created by our brains?

The idea of a god or goddess, no matter how old, has always been responsible for a single thing, namely bringing people together, especially in times of need. Religion may have very well played a part in the aggregation of the first human societies, when people were much more exposed to the whims of nature than they are today. At this point, the main religions of the world are fairly elaborate, and have tens and hundreds of millions of followers worldwide. But, in the old days, such “complex” gods were not yet invented, and people only believed in the natural forces they saw, as in the Sun, the wind and the Earth itself.

NASA Image Of The Day

| Snapshot of the International Space Station | ||
| On March 13, 2008, the International Space Station passed across the field-of-view of Germany's remote sensing satellite, TerraSAR-X, at a distance of 195 kilometers, or 122 miles, and at a relative speed of 34,540 kilometers per hour, or more than 22,000 mph. In contrast to optical cameras, radar does not 'see' surfaces. Instead, it is much more aware of the edges and corners which bounce back the microwave signal it transmits. Smooth surfaces such as those on the station's solar generators or the radiator panels used to dissipate excess heat, unless directly facing the radar antenna, tend to deflect rather than reflect the radar beam, causing these features to appear on the radar image as dark areas. The radar image of the station therefore looks like a dense collection of bright spots from which the outlines of the space station can be clearly identified. The central element on the station, to which all the modules are docked, has a grid structure that presents a multiplicity of reflecting surfaces to the radar beam, making it readily identifiable. This image has a resolution of about one meter (about 39 inches). In other words, objects can be depicted as discrete units--that is, shown separately--provided that they are at least one meter apart. If they are closer together than that, they tend to merge into a single block on a radar image. Since this image was taken, the station has expanded and is more than 90 percent complete, including a full complement of solar arrays. Image Credit: DLR... | ||
