Azerbaijan’s drones owned the battlefield in Nagorno-Karabakh – and showed future of warfare

  Azerbaijan’s drones owned the battlefield in Nagorno-Karabakh – and showed future of warfare Azerbaijan used oil wealth to buy attack drones from Turkey and Israel. It was a huge advantage. Drone strikes — targeting Armenian and Karabakh soldiers and destroying tanks, artillery and air defense systems — provided a huge advantage for Azerbaijan in the 44-day war and offered the clearest evidence yet of how battlefields are being transformed by unmanned attack drones rolling off assembly lines around the world.

Malaysian researchers have developed a method to transform the fibre found in normally discarded pineapple leaves to make a strong material that "We are transforming the leaf of the pineapple into a fibre that can be used for aerospace application, basically inventing a drone ," he told Reuters at a

Researchers in Malaysia have found a way to turn fiber from pineapple leaves into material sturdy enough to make drone frames. Professor Mohamed Thariq Hameed Sultan of Putra University told Reuters that drones built with the material had a higher strength-to-weight ratio than frames made with synthetic fibers. They're cheaper and lighter, too.

A damaged frame can be buried and the bio-composite material will degrade within two weeks, according to the researchers. They say prototypes made from the material have flown to around 1,000 meters (3,280 feet) and, like many other drones, they can stay aloft for about 20 minutes. The researchers aim to make larger drones that can carry bigger payloads, such as imaging sensors for agricultural use.

The project, which started in 2017, is geared towards finding sustainable uses for pineapple waste. Farmers often burn or discard of the leaves after harvest, which can cause air pollution. Selling the waste instead would increase their income and may benefit the environment.

Fact check: Health benefits of bay leaves need more study .
There may be health benefits associated with bay leaves, but most of the claims in viral social media posts are distorted, exaggerated or inaccurate.   Bay leaves are not a replacement for a pharmacy.
