Aerial Photos Reveal Mysterious Stone Structures: The area near the Azraq Oasis in Jordan has hundreds of wheels, large structures made of stone that date back at least 2,000 years. These wheel structures are often found on lava fields and range from 82 feet to 230 feet (25 meters to 70 meters) across. Archaeologists used to believe that the Azraq Oasis wheels were used as a cemetery although that is now in doubt.

What does it feel like to fly over planet Earth?

A time-lapse taken from the front of the International Space Station as it orbits our planet at night. This movie begins over the Pacific Ocean and continues over North and South America before entering daylight near Antarctica. Visible cities, countries and landmarks include (in order) Vancouver Island, Victoria, Vancouver, Seattle, Portland, San Fransisco, Los Angeles. Phoenix. Multiple cities in Texas, New Mexico and Mexico. Mexico City, the Gulf of Mexico, the Yucatan Peninsula, Lightning in the Pacific Ocean, Guatemala, Panama, Columbia, Ecuador, Peru, Chile, and the Amazon. Also visible is the earths ionosphere (thin yellow line) and the stars of our galaxy.

The original data is from NASA’s “The Gateway To Astronaut Photography of Earth”.

Preserved for 70 to 85 million years, these feathers are part of a newly revealed trove of likely dinosaur and bird plumage found trapped in amber in Alberta, Canada.
The unusual find suggests a wide array of plumed creatures populated the time period—sporting everything from seemingly modern feathers to their filament-like forebears—and that even by this early date, feathers had become specialized, for example, for diving underwater, a new study says.

This kitten may have the key to protect humans against HIV, the lentivirus that causes AIDS. He was genetically modified at the Mayo Clinic in Rochester, Minnesota. And yes, he glows in the dark.
His fluorescent fur and claws—which glow green in certain lighting—are not a side-effect of the gene that makes the cat resistant to the feline form of the HIV, known as the Feline Immunodeficiency Virus. It’s caused by another gene that produces the Green Fluorescent Protein, which is naturally produced by the jellyfish Aequorea victoria.
