In a tweet last month, astronaut Buzz Aldrin informed the world that he was responsible for taking the first ever selfie in space during the Gemini 12 mission in 1966. The mission took place from November 11-15 lasting 3 days, 22 hours and 34 minutes. The two-man crew included Aldrin and James Lovell Jr.
The mission was Aldrin’s first spaceflight. He would later become the second person to ever walk on the moon after Neil Armstrong on 21 July 1969. (Via.)

Researchers at the University of California San Diego have designed an electronic tattoo—a small, flexible circuit board that can be worn just like the Spiderman temp tats I used to stick on my face—that produces an electrical current.
It works by stripping the electrons from lactate, a byproduct of sweat, with an enzyme imprinted on the e-tattoo’s sensor. In other words, it produces power from your nasty workout juice. And, the researchers say, the technology could eventually generate enough electricity to run devices like phones, smart watches, and heart monitors.
"These represent the first examples of epidermal electrochemical biosensing and biofuel cells that could potentially be used for a wide range of future applications," said research lab director Joseph Wang in a statement.
