Argentina’s senate is poised to approve a sweeping overhaul of labour laws aimed at weakening trade unions and lowering labour costs for businesses.
立春那天去超市买春饼，空气里刺骨的寒气似乎一点也没有春意。不承想，隔两日再次出门，照例把脖子往衣领里缩，却隐约发现整个冬天伴着哨音蛮横且有刺痛感的气流正在消退，虽寒意尚在，风却变弱了、变软了，感觉脸上装备的那层抵御寒冬的铠甲，迅速融作一袭若有若无的轻纱。微风徐来，习惯中那种粗粝的刮痛感不见了，取而代之的是一种在清泉里漂洗了许久的凉润润的、绸缎般的温润触感。这变化极其轻微，似乎正缓慢地从时间的罅隙、从空间最微末的颤动中溢出，仿佛宇宙经过漫长的沉睡，打着困意尚未全消的呵欠渐渐苏醒，意在向世间表明，季节的轮替正一如既往地、温和而守时地、捧着新生的希望如期而至。

"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.
