On Sunday, September 27th, skywatchers will witness the grand finale of the rare lunar eclipse tetrad (series of four consecutive total lunar eclipses). And it promises to be quite a show. That's because this one involves a full moon and perigee. This means that the celestial body will be at its closest distance to earth, giving it a larger than life appearance. The last time the world witnessed this phenomenon was in 1982, and the next one will not be until 2033!...

On August 28, six researchers who barely know each other made their way to the slopes of the Mauna Loa volcano on Hawaii's Big Island for a year-long "vacation." However, the crew of three men and three women that includes a soil scientist, a doctor, a post-grad architect student, and an astrobiologist, did not check into a fancy resort.

They were rising to the Ice Bucket Challenge that encouraged people to either douse themselves or donate $100 USD towards ALS research. The dare that went viral globally enabled the Foundation to raise an astounding $115 million USD in a few short months. Now, just a year later, the generous donation is helping facilitate new breakthroughs in the disease that currently has no cure....

The octopus has long fascinated scientists. The intelligent cephalopods have been known to use coconut shells for mobile homes and armor, disable their suckers to avoid becoming a tangled mess, plot escapes from aquarium enclosures, and even predict World Cup soccer game outcomes....
