The first deep-sea experimental application of diamond quantum vector magnetometer.

A team from the University of Science and Technology of China of the Chinese Academy of Sciences—working with pure-red PeLEDs— has identified and addressed the root cause of PeLED efficiency loss at high brightness by introducing a novel material design that enables record-breaking device performance.

A new large-scale Ward-type tornado simulator has been built at Central South University in 2023. Stationary tornado-like vortices are generated and tested to explore the characteristics of the velocity field and surface pressure field. The results show the significant influence of swirl ratios and little influence of fan speeds on vortex structures. The simulator has the good capability of generating tornado-like vortices.

Fifty-two people have died on Catalan roads so far this year, according to data from the Catalan Traffic Service. Although there have been fewer accidents in the first four months of the year than in the same period last year, accidents continue to have a terrible impact: more than 3,500 people were involved in 2,414 traffic accidents in 2024, 48 of them with fatalities. In more than 85% of cases, the human factor is to blame with distractions, fatigue, drowsiness, and consumption of alcohol and other substances being recurrent causes. Aware of this, the automotive industry is working on active safety systems that, among other things, monitor drivers' alertness and warn them when they are not paying attention. Researchers from the NEPHOS research group have developed a prototype capable of doing this more efficiently than conventional systems.
