Mesh routers, or mesh Wi-Fi systems, use multiple devices (or nodes) across your home to create a larger home network. Essentially, you have multiple routers around your home with these systems, and that will hopefully provide the best coverage possible. Wi-Fi extenders, on the other hand, are usually just one device that extends your existing Wi-Fi signal, and they often require you to switch networks when connecting. Wi-Fi extenders are more affordable, though, and are great if you’re traveling or need a Wi-Fi signal in harder-to-reach areas.

冷冻电镜技术的思路非常巧妙：将含生物分子的溶液制成薄薄的水膜，在毫秒之内投入到零下180摄氏度左右的液态乙烷中，使其瞬间形成“玻璃态冰”——既不膨胀结晶也不蒸发，将分子“冻结”为瞬间姿态。这种“速冻”方式就像按下暂停键，把生命分子的活动定格在某一帧。
