Neural network helped archaeologists find huge geoglyphs in Peru
Japanese archaeologists have successfully adapted artificial intelligence to search for geoglyphs - huge images drawn on the surface of the Nazca Plateau in southern Peru.
Presumably, the age of the “drawings” reaches several thousand years. The outlines of many of them erased in a semi-desert climate and difficult to discern from the satellite human eye, so the helpers harnessed artificial intelligence.
Neural network analyzed pieces of satellite images with a resolution of 112 × 112 pixels, each of which corresponded to a real area of 120 m². The AI lab output was supervised by archaeologists, culling and double-checking false positives. The process took six months and ended up being a huge success.
Over the past century, only 430 “rock” images have been discovered. In the last six months, three hundred. Of these, the neural network itself identified almost 180 geoglyphs, and the rest nearby scientists noticed themselves while looking at the findings of the neural network.
Scientists intend to improve the algorithm for analyzing images and go on a search again.

Eve's ring, discovered in coal in 1880
A farmer in Colorado purchased coal and discovered a ring in one of the chunks. Realizing it could be worth a significant amount, he consulted experts.
It is estimated that the ring is at least 60 million years old, based on the layers of rock in which it was found. The artifact was named "Eve's Ring".
In 1908, the ring was studied using advanced technology. It turned out it had been oxidized fo

Aviation technology: a parachute for the entire airplane
The American Cirrus was the first to launch mass production of these back in the late 90s - after an accident in which one of the company's founders was involved. Since then it has been their trademark.
Now such systems are also found in some single-engine models of Slovenian Pipistrel, American ICON, Van's, Cessna and not only. Basically all of them offer parachute as an option, but Cirrus has i
