Nonhuman ‘Hands’ Found in Prehistoric Rock Art

To know where we are going and why, we must first know from whence we came. So, science. =)


The roughly 8,000-year-old “hands” painted on a rock wall in the Sahara Desert aren’t human at all, as researchers originally thought, but are actually stencils of the “hands” or forefeet, of the desert monitor lizard, a new study finds.

These tiny lizard hands are intermingled with paintings of human adult hands, which ancient rock artists stenciled around using red, yellow, orange and brown pigments, the researchers said.

It’s unclear why these ancient people used both human and lizard hands as stencils, but the finding may provide clues about the mysterious people who lived in the Sahara about 8,000 years ago, the researchers said. [Gallery: See Amazing Images of Cave Art].

Bioluminescent Bacteria Could Light Up The Streets Of Paris

When science does amazing things; it definitely creates the “WOW” factor like nothing else can.


A French company is harnessing the power of bioluminescent bacteria to light up public areas.

Glowee, a Parisian start-up, plans to use bacteria found in squid to illuminate shop fronts, public spaces, and installations, with the hope of lighting up whole streets with these microbial lamps.

Robot shows off flexible, octopus-like skin

TweetScientists from Cornell University have come up with a new form of technology that holds a lot of promise in the field of electronics, where stretchy screens and other products are shaping up to be the wave of the future. Scientists from Cornell University have come up with a new form of technology that holds a lot of promise in the field of electronics, where stretchy screens and other products are shaping up to be the wave of the future.

The Cornell study published yesterday in Science takes a look at a pliable type of “skin” that changes colors and flexes and stretches based on the pressure it senses. This skin is said to be similar to that of squid and octopus, but, according to Cornell Organic Robotics Lab researcher Chris Larson, it’s “much, much, much more stretchable than human skin or octopus skin.” He compared the stretchy skin to something akin to a “rubber band or a balloon.”
