The Arctic is one of the coldest places on Earth, but in recent decades, the region has been rapidly warming, at a rate three to four times faster than the global average. However, current climate models have been unable to account for this increased pace. Now, researchers at Kyushu University have reported in a study, published April 29 in Ocean-Land-Atmosphere Research, that clouds may be to blame.

Grassroots rugby concussion guidelines need to be improved as players’ brains remain altered despite them being symptom free and cleared to play, researchers have found. The University of Essex is the first to follow an amateur club across a gruelling 22-game season using brain imaging technology. The study led by Dr Ben Jones found seven out of eight concussed players still had abnormal brain responses 25 days after injury - despite feeling well enough to return to the field under Rugby Football Union clearance protocols.

A research paper by scientists at Beijing Institute of Technology presented a magnetic shaftless propeller-like millirobot (MSPM) that possesses the capabilities of rotating-based multimodal 3-dimensional motion and cargo transportation with untethered manipulation.
