Here’s What You Need To Remember: In 2018, Chinese scientists said they were developing a laser-equipped satellite that could detect submarines. The idea is to use laser beams of various colors that ...

Space scientists from China have revealed a breakthrough in magnetic detection technology that could boost the country's underwater warfare capabilities. During offshore trials, their drone-mounted ...

According to the paper, there are two main ways scientists could collect data on exoplanet magnetic fields. First is direct detection using two "effects" known as the Hanle and Zeeman effects. The ...

While metal detectors are useful for detecting land mines, they can be fooled by buried metallic debris … plus some mines don't contain any metal. A new system is claimed to work better, by reading ...

Recent studies have shown metallic objects have their own magnetic fingerprints based on size, shape and physical composition. Scientists look to leverage these observations to potentially create a ...
