Researchers see a possibly habitable planet in our neighborhood

Twenty light years sounds like a massive distance, but it is just a stone throw away when talking in astronomical distances. That happens to be our distance from Gliese 581d, a planet orbiting a red dwarf star, with a stable atmosphere, comfortable temperatures and plenty of water. Gliese planetary system has been of particular interest for quite some time now, getting some limelight with scientists speculating possibility of life on another planet, the 581g. Scientists now believe the 581g may not be such a great place after all, and it may just be a fairytale coming out of errors in measurement. The 581d though, is sure to exist, lying on the fringes of the star systems habitable zone, called the Goldilocks zone.

The brain in love [pic]

Frankly, the heart gets too much credit for love. While its boss, the brain sits there doing a lot of hard work, and never getting any credit. This image of the brain was made using MRI scans of people who claimed they were experiencing passionate love, material love or unconditional love. It is this situation that gets neurotransmitters and chemicals into action, making us feel the pleasures of love.

Iceland’s ash plume as captured by weather satellites

Explosion of Iceland’s Grimsvötn volcano has already made news, sending off a 7 mile high plume of ash and dust into the atmosphere. These series of images were captured by US GOES 13 satellite, and stitched together to create this video-effect for us. So how massive is the ash plume? For comparison, the blue lines mark Iceland’s area. The GIF image is after the jump.

X-Ray sees dog slurping, understands the mechanics involved [video]

Exploiting the magic of X-Ray cameras and high frame rate, scientists evolutionary biologist Alfred Crompton and some Harvard colleagues have found the exact way a dog drinks. It is generally believed that dogs scoop liquids into their mouth from the underside of their tongues, but now it seems they are quite similar to cats, pulling columns of water into their mouth using neat fluid mechanic tricks. Basically, the tongue hits the liquid and snaps back, forcing water into the space behind it.

Decommissioned AK-47 converted into a guitar

Colombian sculptor César López creates some of the most badass looking guitars that presumably make other guitars look woefully inadequate with their war stories. The sculptor noticed many armed guards carried their guns like they would a guitar, leading Lopez towards the idea of fashioning guitars from the scary AK-47s. Lopez does not sell his creations, but hopes that “in the end the gun dies and the guitar is born.”
