yaks

Ukrainian forces are using a Yak-52 propeller-driven trainer with a backseat gunner armed with small arms to intercept Russian attack drones. Newly circulated footage shows the gunner firing at a drone in flight, then making an obscene gesture toward it. The clip has drawn attention for the improvised, low-tech nature of Ukraine's drone defences.

Scientists have discovered an extinct bovine species in Siberia, identified as a previously unknown relative of yaks. The find sheds light on the lost diversity of Ice Age megafauna in the region and the evolutionary history of yak-like animals. Coverage is so far limited, with the discovery reported as revealing a lineage science did not know had existed.
