Engadget’s own Sam Rutherford is on-site in San Francisco for the new hardware launch and will have hands-on impressions. We’ll follow that up with official reviews in the next week. But if you can’t wait for our final verdict, here’s how to pre-order Samsung’s Galaxy S26 phones and the Galaxy Buds 4 today.

我的青少年时代在黄土高原腹地甘肃省定西市安乐村度过。每逢暑假，我和哥哥总会在外婆家住几天。外婆家不远处那片被庄稼层层环绕的黄土山，是我最熟悉的风景。我们经常踩着田埂间没膝的狗尾巴草与蒲公英，深一脚浅一脚地攀爬。那时的我还不知道，这片承载童年欢声笑语的“土山”，是第四次全国文物普查中新发现的北宋故城遗址——张川城遗址。这15到20厘米厚、层层叠叠的夯土层里，竟藏着古人筑城戍边的智慧。那些与庄稼共生的黑釉、褐釉陶瓷片，曾是北宋先民碗碟中的烟火生活，沉淀着上千年的光阴。，推荐阅读服务器推荐获取更多信息

"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.
