A pioneering new test that can recover fingerprints from ammunition casing, once thought nearly impossible, has been developed by scientists at Ireland's Maynooth University. They have developed a unique electrochemical method which can visualise fingerprints on brass casings, even after they have been exposed to the high temperature conditions experienced during gunfire.   

Flowering Chinese cabbage, a staple leafy vegetable across Asia, has undergone decades of breeding to improve adaptability, productivity, and quality. 

A research paper by scientists at The Chinese University of Hong Kong proposed a 3D radar-based control scheme that realizes the navigated locomotion of microswimmers in 3D space with multiple static and dynamic obstacles.

The new research paper, published on Jun. 2 in the journal Cyborg and Bionic Systems, presented a 3D hierarchical radar with a motion sphere and a detection sphere is firstly developed. Using the radar-based avoidance approach, the desired motion direction for the microswimmer to avoid obstacles can be obtained, and the coarse-to-fine search is used to decrease the computational load of the algorithm. Three navigation modes of the microswimmer in 3D space with dynamic conditions are realized by the radar-based navigation strategy that combines the global path planning algorithm and the radar-based avoidance approach.
