New Vaccine Protects Against Fentanyl

Scientists at the University of Houston have developed a vaccine that protects against fentanyl, a synthetic opioid that contributes to the risk of fatal overdose. The team of researchers tested the vaccine on 60 rats, finding that it successfully prevented the drug from entering their brain. Once immunized, the rats were able to produce anti-fentanyl antibodies to stop the drug’s effects further. The vaccine—which can …

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 …
