The rise of the malicious use of drones

Drones are legally categorized as aircraft, so when homeowners see a drone hovering over their private property, it is illegal to shoot them down. As drones become more commercially available, their illicit use is also increasing. Celebrities have reported incidents of drone privacy invasions and events planners often deploy anti-drone systems to prevent incursions.

Space archaeology studies space trash in the context of heritage and social meaning

Some orbiting objects, such as Elon Musk's Tesla, have symbolic or historical importance, despite being functionally worthless. The oldest human-made object in Earth's orbit is Vanguard 1, a grapefruit-sized satellite launched in 1958. The strangest may be an experimental, inflatable space station containing live cockroaches.

Theorists have long believed that sudden increases in pizza deliveries near the Pentagon signal a major event is about to occur. Historical examples include the CIA ordering 21 pizzas the day before the beginning of the Gulf War, and another surge of deliveries before former President Bill Clinton's impeachment hearings. Citizens have since begun monitoring food orders in the area. See a tracker of Pentagon pizza orders here.

Hardline China critics in the US worry that China's Belt and Road Initiative is a Trojan horse for military expansion efforts

The Belt and Road Initiative, initially launched in 2013 to develop trade routes throughout Europe, Asia, and the Middle East, has evolved into a larger infrastructure development initiative in developing countries.
