New Research Supports the Idea that There Was Once Life on Mars

A recent study from the journal “Earth and Planetary Science Letters” presents new findings about the early evolution of Mars. By creating a newly developed model of Martian atmosphere through time, researchers found that Mars—in contrast to the frozen desert it is now—was born with lots of water and a dense atmosphere that could have harbored warm-to-hot oceans for millions of years. This discovery likens …

The World’s Smallest, Remote-Controlled Walking Robot

Researchers at Northwestern University created a crab-shaped robot that is smaller than a flea, measuring just half a millimeter—making it the smallest-ever remote-controlled walking robot. The robot can bend, twist, crawl and leap, all without relying on complex hardware. Rather, the micro-robot’s movement utilizes an alloy that can “remember” shape when heated. Researchers point a laser beam at the robot to heat up several targeted …

The Most Detailed Map of the Moon Ever Made

Researchers from the Chinese Academy of Sciences, China’s Institute of Geochemistry and other organizations worked together to compile all known information about the moon’s surface in a new project that culminated in the most detailed map of the moon ever created. Using a 1:2,500,000 scale, the map denotes all discovered rocks, craters, basins and 90 different types of structures on the lunar surface. This is …
