These handy wireless devices do exactly what their name suggests: extend your Wi-Fi network so it covers more areas of your home. Most wireless extenders plug into an AC outlet and connect to your existing router so they can then rebroadcast it to spots that your router alone may not cover well. As a rule of thumb, you’ll get the best results by placing the extender half way between your router and the dead zone you’re trying to fix or improve your W-Fi connection and strengthen the wireless signal.

There is a plan to prevent such a strike—the Space Surveillance Network, a bevy of sensors that the military uses to track space debris. NASA monitors what’s unofficially known as the “pizza box,” a sort of no-fly zone around the ISS. When pieces of debris are predicted to enter the box—if there’s at least a 1 in 100,000 chance of collision—mission controllers order avoidance maneuvers, firing thrusters that move the ISS and dodge the trash. The technique has been used dozens of times since the first ISS module launched in 1998. But the system only tracks about 45,000 larger pieces, and all sensors have noise. Plus, risk thresholds can miss stuff, sometimes badly. In 2025, Chinese astronauts were briefly stranded at their station after debris hit their return vehicle.
在移民與邊境安全上，特朗普自誇大幅削減非法移民、強化南部邊境，未提及明尼蘇達執法行動（民調顯示不受歡迎）。對伊朗，他警告「午夜之鎚」行動已摧毀部分核設施，若繼續追求核武將面臨嚴重後果：「我偏好外交解決，但絕不容許世界頭號恐怖主義贊助國擁有核武。」他未透露是否考慮軍事打擊。
