Russia's Pantsir air defence system combines rapid-fire 30mm cannons and high-velocity surface-to-air missiles on a single mobile chassis. Known as the SA-22 Greyhound, it tracks targets using advanced radar and can fire on the move to destroy drones, planes, and cruise missiles.

How Russia's Pantsir air defence system works

Russia's new ZAK-30 Citadel is an automated 30mm anti-drone system designed to protect critical infrastructure. It uses advanced radar and thermal sensors to track small drones, destroying them with programmable airburst shells that detonate into a shrapnel cloud.

Russia's new drone-killer: How it finds small targets

The Patriot missile system is incredibly hard to replace due to extreme cost asymmetry and sluggish industrial supply chains. With each PAC-3 MSE interceptor costing US$4 million and taking 30 months to build, militaries face a ruinous trap when firing them at cheap drones.

Patriot missile system: Why it is so hard to replace

The US is facing a critical Patriot missile shortage, with stockpiles falling to just 25 per cent of required levels following heavy usage in Ukraine and the Middle East. To fix this, the Pentagon awarded Lockheed Martin a US$58.6 billion contract to triple production by 2030.

Notable Einstein Rings in Astronomy

An Einstein ring is a circular appearance of light around a celestial object, caused by gravitational lensing. This occurs when a massive object, such as a galaxy or a black hole, bends the light from a more distant object behind it. The effect, predicted by Einstein’s general theory of relativity, forms a ring when the alignment between the source, lens, and observer is nearly perfect.

In early 20th-century Germany, a horse named Clever Hans appeared to solve maths problems and understand human speech. However, investigations revealed that the horse was responding to subtle, subconscious cues from his trainer rather than genuinely understanding language. This case remains a key example of how animals may seem to comprehend language while actually reacting to external stimuli.
