Watch this video of tiny flying RoboBees in action

Jun 6, 2016

A group of Harvard scientists have a vision: to build a tiny robot that can fly, work together in groups, and even pollinate flowers like a honeybee. Meet RoboBee, whose latest feat was published in Science. The 80-milligram robot can fly to a surface, perch on it using electrostatic forces, and gently take off from that surface — saving valuable energy in the process.

Did you know GPS used to be controversial? Here’s how it survived.

Jun 5, 2016

In the early 1970s, the idea for a satellite-based modern navigation system was controversial within the United States Air Force. Many in leadership didn’t want anything to do with the project that would become our now-ubiquitous GPS — they thought the money was better spent on putting more planes in the air.

How much of your personal data do you give up when you use your smartphone?

Each call, post, or search from your smartphone leaves a trail of hidden digital data that you might not see, but that can be collected by organizations interested in your info.

In 2013, Edward Snowden leaked documents that showed the NSA was collecting phone metadata. After these leaks, the NSA changed its guidelines. But where do we stand now? Have these NSA changes increased our privacy? What exactly has changed?

The NASA Kepler mission scientists have confirmed a record haul of exoplanets: 1,284. The objects were all spotted in the patch of sky between the constellations of Cygnus and Lyra, and the announcement more than doubles the number of exoplanets, or a planet that orbits a star other than the sun, known to science.

Bernd Heinrich, a birdwatching expert and professor emeritus of biology at the University of Vermont, has been known to go to extremes in his bird-watching pursuits. There is, for example, the time he drilled a hole in the wall of his home in order to get a better view of a bird building its nest. 

Want to try mushroom hunting? Here are a few tips from a pro.

This octopus may evoke the spirit of life, but it never swam the ocean depths. It’s made of glass.

The specimen is one of thousands of meticulously detailed marine invertebrate models fashioned between 1863 and 1890 by a father-son glassworking duo, for the primary purpose of research and education. Collectively, their work depicts more than 700 different species — including various anemones, squids and sea stars — found in waters around the globe.

Drones might one day be able to alert swimmers to the presence of sharks in the waters off North Carolina’s coasts. But first, researchers need to know how accurate unmanned aircraft are at spotting sea creatures.

As the weather warms in the southern Appalachians, the blue ghosts start to appear.

No, they’re not otherworldly or apparitional — they’re just insects. Blue ghost fireflies (Phausis reticulata), native to the region, begin their mating season as spring slides into summer, usually around the beginning of June, although they’re already starting to appear this year, says Jennifer Frick-Ruppert, a professor of biology and environmental science at Brevard College in North Carolina.
