Want to spy on your neighbors from outside? In a similar situation, MacGyver rigs up a distant laser microphone. When a conversation goes on inside a room, it creates vibrations in the air—vibrations that carry to the glass of a window. All a would-be eavesdropper need do is point a laser at the window, aiming the beam so that it bounces off the glass and returns to hit a light-sensitive photocell. The photocell can detect fluctuations in the laser beam—and if you wire that photocell to a speaker, it will translate the window's vibrations back into sound waves.
If you were on the internet this week, as you may have been if you're reading this, then you probably noticed some sites are having trouble loading, and others are not working at all.

Last week, a group called the "Shadow Brokers" stole 234 megabytes of data from the National Security Agency (NSA). The leak included information about the "cyberweapons" the NSA uses to hack suspects and enemies, and a tracking code that reveals the fingerprints of the NSA's malicious software.
The night is kind to radio. Free from the deadlock of rush-hour commercials, DJs can play with the format, delve into back catalogues, and mess around with B-sides. The night is also kind to radio listeners, especially those on the edge of service. When radio waves reach the ionosphere in the atmosphere, they can bounce down to earth, and on some nights where the ionosphere is dense with free electrons, that means radio signals can go farther.
