The advent of 3-D printing is transforming how astronauts work in space. Recently, astronauts on the International Space Station created a tool known as a ratchet wrench, by printing it on the space station's own 3-D printer. A design file sent electronically from NASA on Earth to the ISS instructed the printer to create the wrench from 104 successive layers of plastic.

Turn on your cell phone and the screen lights up for you to see. Flip a switch and a room turns from dark to bright. Decorate your home with winter holiday candles and lights, or watch fireworks light up the sky on July 4th...Light and light-based technologies affect every day and nearly every part of our lives. Often we take light for granted, but in 2015 the world will be paying a lot more attention during the International Year of Light and Light-Based Technologies.

Blockbuster sci-fi movies like Interstellar and Gravity and bestselling novels like The Martian raise many questions about space travel and human survival on other worlds. What happens to time during long space voyages? How will astronauts handle emergencies with limited supplies and equipment? Where might humans find another Earthlike planet to colonize? How would they survive there? At Howtosmile.org, learners think like scientists and engineers to explore such challenges through both hands-on and online activities.

Driven almost to extinction, giant tortoises of the Galapagos are back in full force. On average these island dwellers live more than 100 years, but were nearly wiped out by hunting, habitat destruction and introduced animal predators that fed on tortoises' eggs and young. Now, some 50 years of work—including captive breeding and protection in the wild—mean the Galapagos tortoises will survive as one of only two remaining groups of giant tortoises on Earth.

Despite major news coverage of ebola, many student learners and adults may still know very little about disease transmission and epidemics. Howtsmile.org activities that model how infectious diseases spread, how medical detectives investigate them, and how disease transmission can be blocked increase understanding of health risks to both individuals and large populations.

just in time for Halloween, National Geographic brings humans face to face with animal "zombies" of a "freakish world where parasites compel their hosts to do their bidding." Three graphic novellas on the National Geographic website tell eerie stories of parasites and the real "walking dead" they prey on and live off.
