细胞外囊泡里装的啥宝贝，是改善 AD 认知的核心分子？测序结果显示，运动后肌肉分泌的囊泡里，一种叫 miR-378a-3p 的分子含量飙升。而且，大脑里的miR-378a-3p，绝大部分来自肌肉，不是大脑自己产的。向 AD 小鼠海马注射 miR-378a-3p 激动剂，或通过 AAV 病毒实现骨骼肌特异性过表达该分子，均能激活 DAM、减少淀粉样斑块、改善认知；而敲低该分子则会抵消运动的作用。此外，尾静脉注射运动源性 SKM-EVs 可显著改善 AD 小鼠认知，进一步证实 SKM-EVs 及其携带的 miR-378a-3p 的核心作用。
Riki Ellison, chairman of the Missile Defense Advocacy Alliance, said the U.S. military could shift interceptors from one part of the world to another or get them from allies if needed. He also noted the Pentagon effort to get defense contractors to boost production.

The change of plan also comes as Artemis 2 has faced multiple delays in recent months. The Space Launch System (SLS) heavy-lift rocket has, once again, proven to be temperamental. NASA had planned to launch Artemis 2 in early February, but pushed the flight back after it caught a hydrogen leak during a fueling test. More recently, NASA delayed the mission to give its engineers time to fix a helium pressurization issue in the upper stage of the SLS. At the earliest, the mission can now get underway on April 1.，这一点在whatsapp中也有详细论述
