The Dutch ethical smartphone brand Fairphone is back with its six-generation Android, aiming to make its repairable phone more modern, modular, affordable and desirable, with screw-in accessories and a user-replaceable battery.
"Tuning frictional behavior on the fly has been a long-standing engineering dream," said co-author Katia Bertoldi of Harvard University. "This new insight into how surface geometry governs slip pulses paves the way for tunable frictional metamaterials that can transition from low-friction to high-grip states on demand.” In addition, the dynamics revealed by these results are similar to those of tectonic faults and thus give scientists a new model for the mechanics of earthquakes, according to their new paper published in the journal Nature.

Responsibility for carrying out the medical assessment work is being taken over by Maximus UK Services Limited - another provider whose parent company is based in the US. The exact date when it will start is yet to be confirmed.
（十）加强组织领导。各级教育部门、各级科协应加强对高校科普工作的统筹协调。高校应认真履行科普社会服务职能，将科普工作纳入学校中长期发展规划和年度计划，建立健全由党委领导、高校科协牵头、多部门协同的常态化科普工作机制，定期研究部署科普工作。
