Ancient Pyramid in Mexico Collapsed Into A Pile of Rubble

On the night of July 29, the 15-meter-high (roughly 50-foot-high) square monument located in the state of Michoacán suddenly slumped under the pressure of incessant rain, its south wall crumbling into a pile of rubble.

The pyramid was once one of the best-preserved monuments of the Michoacán Kingdom civilization.

The "incessant rain" is described as a product of climate change.

British soldiers have successfully taken down drones with a radio-wave weapon.

However, the nature of the technology means that a wide beam is used, which is effective at disabling multiple drones simultaneously, but lacks target discrimination. Hence, Sgt Mayers, the first British soldier to bring down drones using a radiofrequency weapon, described it as "a great asset to Layered Air Defence."

The MOD believes the system, which it estimates costs 10p per shot fired, "could provide a cost-effective complement to traditional missile-based air defence systems."
