Cats may have their own chemical ID cards, study finds

A groundbreaking study reveals that cats employ specific fatty acids in their urine, which act as chemical identifiers for each feline. These branched-chain fatty acids leave a persistent scent trail, allowing cats to recall individual urine aromas long after they've faded. The findings imply that the kidneys may help store these scent molecules, offering new insights into how cats communicate…

Some of China’s 11,000 mega bridges could be at risk from small drones: study

Scientists in China have simulated a drone attack on one of the country’s major suspension bridges to determine the vulnerability of key transport hubs to modern warfare tactics. The researchers found that a drone carrying just 30kg (66lb) of TNT could trigger a bridge collapse if it detonated within inches of the main suspension cable at…
