一 |     A Russian governor was accused by critics on Sunday of “discrediting Russia’s armed forces” after telling residents in her region that the country had “no need” for its war in Ukraine.Natalya Komarova, the governor of the Khanty-Mansiysk region and a member of President Vladimir Putin’s governing United Russia party, made the remarks during a meeting with residents in the Siberian city of Nizhnevartovsk on Saturday.Critics have called for authorities to launch an investigation into her remarks, but Komarova hasn't been detained or faced any charges so far.A video of the event posted on social media showed the politician being confronted by the wife of a Russian soldier who said that mobilized men had been poorly equipped for the front line.Komarova told residents that Russia hadn't been prepared for the invasion of Ukraine.“Are you asking me (why your husband does not have equipment), knowing that I’m the governor and not the minister of defense?”, the 67-year-old said.“As a whole, we did not prepare for this war. We don’t need it. We were building a completely different world, so in this regard, there will certainly be some inconsistencies and unresolved issues,” she said.Komarova’s comments quickly spread online, reportedly prompting pro-war activists to denounce the politician to authorities for “discrediting Russia’s armed forces.”News outlet Sibir.Realii reported that its journalists had seen a letter from the director of a Siberian non-profit organization, Yuri Ryabtsev, to Russia’s Minister of Internal Affairs, calling for a further investigation of Komarova’s comments.Days after Putin sent troops into Ukraine on Feb. 24, 2022, Russia’s Kremlin-controlled parliament approved legislation that outlawed disparaging the military and the spread of “false information” about Moscow’s invasion of Ukraine.Russian courts have used the legislation to hand out fines and prison terms to opposition critics, including those who describe Moscow’s full-invasion of Ukraine as a war, instead of using the Kremlin’s preferred euphemism of “special military operation.”。    

    A drone made of bamboo-based composite materials is seen in flight. Photo: official WeChat account of Long BambooA Chinese team has developed a drone using bamboo-based composite materials after making a breakthrough in a technique that allows bamboo to be flattened while preserving its tough outer layer. The drone has completed multiple test flights, China Central Television (CCTV) News reported.
Long Bamboo, a company based in East China's Fujian Province, developed the technique that preserves the bamboo's tough outer layer and allows different parts with different densities of the material to be used according to their properties, improving its overall performance.
In the past, the outer skin of bamboo was often treated as leftover material and eventually burned into low-value bamboo charcoal.
According to a company release in February, bamboo-based composites now make up more than 25 percent of the entire drone, while its fuselage skin is made entirely from the company's own high-performance bamboo composite material.
The bamboo-based material also offers a major cost advantage, costing only about one-quarter to one-tenth as much as aviation-grade carbon fiber. After the drone is retired, the material can naturally degrade, allowing it to effectively "come from nature and return to nature."
The team spent four years building data models, upgrading equipment and refining the material. The resulting drone has a wingspan of more than 2.5 meters but weighs only about 7 kilograms, and has already completed multiple test flights, according to CCTV News.
Bamboo was traditionally used mainly in products such as tableware and furniture. Now, however, the material is finding its way into a wider range of industrial applications. Bamboo fiber is being used in automobile interiors, while bamboo-based materials are also being explored as possible substitutes for plastics, glass fiber and carbon fiber in some applications. 
China has the world's largest bamboo resource base, with about 7.56 million hectares of bamboo forests nationwide. The country also ranks among the world leaders in bamboo resources, bamboo cultivation technologies and the development and utilization of bamboo materials, per CCTV News.
