This oozy, pockmarked image is the surface of Jupiter’s moon Io, from the first complete geologic map of the turbulent orb. Io is the most volcanically active place in the solar system, so it’s of great interest to geologists because its surface is continually refreshing and renewing. It’s the only celestial body where scientists have not seen any impact craters.
In 1736 the Swiss mathematician Leonhard Euler ended a debate among the citizens of Königsberg, Prussia, by drawing a graph. The Pregel River divided the city, now Kaliningrad, Russia, into four sections. Seven bridges connected them. Could a person cross all seven without walking over the same one twice?
New shoes with built-in GPS devices will go on sale this month to help track dementia patients who wander off and get lost. Caretakers can download a smartphone app that allows them to track the person wearing the shoes, which could help patients with Alzheimer’s disease stay in their homes and live autonomously for longer periods.
Maps can only get you so far in life — sometimes you need to veer off the beaten path, take the scenic route, or figure out how to get there as the crow flies. Now Google will help you do that. Helicopter View: When Street View and River View just aren’t enough.
Yesterday, the MTA (the transit organization that covers New York City and its immediately surrounding area) unveiled the very first On the Go Travel Station, a 47-inch touchscreen installed in certain subway stations that provides to-the-minute updates on inevitable delays, as well as a subway map and a trip planner. I went down to the Bowling Green station to try out this first installation.
Even using the most detailed sources, studying history often requires a great imagination, so historians can visualize what the past looked and felt like. Now, new computer-assisted data analysis can help them really see it.
During the next two weeks, you can help build a map of global light pollution, assisting scientists and astronomers as they monitor the loss of virgin night skies. You just have to look at the stars and write down what you see — or, more likely, what you don’t see.
The University of New Mexico discovered a treasure trove of old cutaway schematics of nuclear reactors, dating back as much as 50 years, in the pages of Nuclear Engineering International. If you're interested in nuclear power (or how stuff works) and are looking for some art to hang on your walls, we've got you covered.

NASA’s high-resolution 3-D maps of the moon’s pockmarked terrain the most precise topographic measurements to date—bring us one giant leap closer to a return mission. To create the map, the laser altimeter LOLA on the Lunar Reconnaissance Orbiter bounced five laser beams off the surface of the moon 28 times per second and measured the duration of their return flight to gauge elevation. NASA operators calculated the distortion, or spread, of the beam to find what scientists call roughness; the more distortion there was in the beam, the bumpier the landscape.
As promised, the Commerce Department's National Broadband Map went live yesterday, showing the various types and speeds of internet connections all across the country. It's meant to function both as a tool for consumers and businesses, and as a wakeup call to the country--it's pretty shocking to see just how much of the country lacks high-speed broadband.
