Jet Fuel Made From Air, Sunlight and Water Vapor

Jet fuel is a large driver of climate change but finding sustainable alternatives has proven difficult since many are less efficient when it comes to long-distance aviation. This is why scientists are hopeful about a new jet fuel that uses air, sunlight and water vapor to make a solar-based, carbon-neutral kerosene (the fuel preferred in aviation). Scientists positioned 169 sun-tracking mirrors that reflect radiation into …

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 …

Scientists Engineer Plants to Grow in Total Darkness

New research published in the journal Nature Food reveals that scientists have invented a way for plants to grow in total darkness. To do so, researchers used a process called artificial photosynthesis, where they fed acetate to plants as a carbon source, allowing them to bypass natural photosynthesis. They tested this on yeast, green algae, fungal mycelium, cowpea, tomato, tobacco, rice, canola and green pea, …
