The rapidly rotating, strong magnetic field of Jupiter provides a natural lab that is key to understanding the dynamics of high-energy plasmas. Spectacular auroral X-ray flares are diagnostic of the most energetic processes governing magnetospheres but seemingly unique to Jupiter. Since their discovery 40 years ago, the processes that produce these flares have remained unknown until now. In a new study, planetary researchers from the UK, the US, China...

A special feature in the feeding behavior of the giant panda (Ailuropoda melanoleuca), related to eating bamboo, is the habit to skim the outer green skin of the hard bamboo culm; although the feeding preferences have a seasonal shift, the culm is consumed and skinned during all the year; while eating culm, the outer skin is removed for reasons which until now have remained poorly understood.
