US targets fossil fuel 'super-emitters' of methane

On the hunt for the methane "super-emitters", US President Joe Biden on Friday unveiled a plan to plug oil and gas leaks and tighten regulation as several global emitters vowed to step up efforts to slash pollution of the powerful greenhouse gas.

In search of the perfect match schedule

Sports and competition are inextricably linked. But producing the optimal match schedule is a sport in itself. Mathematician Roel Lambers studied ways to ensure that darts players and teams playing either soccer or a Dutch regional sport called beugelen are matched up as fairly as possible. He defended his thesis on Friday November 11th at the Department of Mathematics and Computer Science.

Magma floods erupt from deeper sources than earlier believed

An international group of geologists has demonstrated with computer simulation that huge magma eruptions can initiate deeper below the Earth's surface than previously believed. Such flood basalt eruptions have caused many global climate changes and great mass extinction events in the past.

The transformation between different topological spin textures

Skyrmions and bimerons are fundamental topological spin textures in magnetic thin films with asymmetric exchange interactions, and they can be used as information carrier for next generation low energy consumption memory, advanced neuromorphic computing, and advanced quantum computing. They have multiple degrees of freedom that can carry information.

2400 new eyes on the sky to see cosmic rainbows

The Subaru Telescope successfully demonstrated engineering first light with a new instrument that will use about 2400 fiberoptic cables to capture the light from heavenly objects. Full operation is scheduled to start around 2024. The ability to observe thousands of objects simultaneously will provide unprecedented amounts of data to fuel Big Data Astronomy in the coming decade.
