Love to sink into your chairs and relax when you get to school? Then you will not be happy to hear that schools all over the world are seriously considering exchanging traditional desks for ones with no seats at all — Yes, that means you will be encouraged to stand through those already too long math and science lessons! Why would anyone even think of putting kids to such cruelty? Experts say it improves their health and helps fight obesity. While that may seem a little far-fetched (牵强的), the officials at the few schools around the world seem to agree.

    Among them are educators from the College Station Independent School District in Texas, who recently completed aweek-long experiment involving 480 students across three elementary schools. The 374 kids that agreed to participate in the study were provided with adevice that helped record step count and calorie consumption over the entireperiod.

    All 25 teachers involved in the study reported that students appeared to be more alert and concentrate better, when allowed to stand. The one thing that did surprise the researchers was that younger kids were more willing to stay standing than kids in higher grades. They believe this may have something to do with the fact that after years ofbeing asked to “sit still”, older kids have a harder time adjusting to this unexpected freedom.

    American schools are not the only ones reporting success with stand-up desks. Four Catholic schools in Perth,Australia, which have been testing them since October 2013, have seen similar results. In May 2014, Grove House Primary School in Bradford, West Yorkshire,became Europe's first test one, with a seven-week trial that involved the useof desks made by Ergotron in their fifth-grade classrooms. While official results are not out yet, early reactions from both teachers and students, have been extremely encouraging.

    The findings of these studies and othersdone previously, all seem to mean that allowing kids to move around in classrooms is a win-win for students and teachers — it helps kids get healthier and provides educators with a more engaged audience.

    If American waterways had ever been voted on the yearbook, the Buffalo River could easily have been named Ugliest. It could be hard to find hope there. It took decades for public perception of the river to shift. But activist citizens, who collaborated with industry, government, and environment groups never gave up on their polluted river—the Buffalo River gradually went from being considered a lost cause to a place worth fighting for. And by now the cleaned—up water is one of Buffalo's biggest attractions.

    By the 1960s, the river was seen as one of the worst sources of pollution pouring into the Great Lakes. The Buffalo River had caught fire many times. The surface had an oily layer, and any fish caught there were not eatable.

    The waterway's fate started shifting in the mid-1960s. Stanley Spisiak was a local Polish—American jeweler by day, but by evening he was the kind of guy who'd chase down dumpers(垃圾车)he spotted on the Buffalo River. By 1966 he found himself winning the National Wildlife Federation's “Water Conservationist of the Year” award. And before long he got a nickname:“Mr. Buffalo River.” But there was only so much he could do—the river was still declared biologically dead in 1969.

    Jill Spisiak Jedlicka is his great-grandniece. She picks up where he left off by directing the river's protector organization, Buffalo Niagara Waterkeeper. Professor Schneekloth and seven friends founded the organization as an all-volunteer nonprofit in 1989, after organizing the first river cleanup that year. Today the group employs 27 full-time workers and has helped oversee the Buffalo River's $100 million restoration.

    So far, the Buffalo River's water quality has restored, but it is still an ongoing issue, as sewage(污水)can overflow into the river after storms. Habitat restoration continues as well; fish and plantings are still being sampled to measure how well it's gone.

The San Francisco Bay Area is one of the most diverse places in America, a wonderful place filled with people from all backgrounds. Each of them drew something different from their own experience. Their stories are the focus of Status Update, an exhibition of 14 projects offered by Dundon and former WIRED contributor Pete Brook. The show at SOMarts uses personal tales to show the Bay Area's culture. 

The Bay Area is a microcosm (缩影) of the national melting pot, a place where people of color comprise 58 percent of the overall population and are a majority in four of the region's five countries, San Francisco in particular is the type of place where you can' t walk down the street without hearing another language. Yet the change is not all for the better. The gap between rich and poor is widening at a frightening speed, and San Francisco is becoming less diverse as minorities escape from the city for more affordable communities elsewhere in the region. 

Status Update reflects these changes and the challenges they bring. Joseph Rodriguez's Faces of Foreclosure features quiet images of people like Ethel Gist, who lost her home in the East Bay suburb of Brentwood six years ago. Photographer Sam records Oakland resident Shannon and his efforts to provide for his daughter. And Laura Morton documents millennials (千禧一代 )hoping to make their way to the top in Silicon Valley in her series Wild West Tech. 

Status Update starts a conversation about how the Bay Area is changing, and what people can do to build up a more just equitable (公正的) society. "I hope people walk away from this show with a little more respect for our neighbors and communities and the ways we depend on one another." Dundon says. "we're all out here together"

The Aviation Industry Corporation of China (AVIC), China's leading aircraft maker, created the country's first fully solar-powered drone (无人机). The large drone, Qimingxing 50, took off at 5:50 pm on September 3rd, 2022, from an airport in Yulin of Shaanxi Province and stayed in the air for 26 minutes before landing on the same runway. AVIC said that all systems of the unmanned plane functioned well on its first flight.

Powered by six electric motors with solar batteries, the drone is designed to conduct long-time operations in near space. Near space is that part of Earth's atmosphere at altitudes of 20 to 100 kilometers. It is above the top altitudes of commercial airliners but below orbiting satellites.

Qimingxing 50, also called "quasi-satellite", features high operational efficiency and eco-friendliness and will be tasked with high-altitude reconnaissance (侦察), forestry fire monitoring, atmospheric environmental inspection, aerial mapping, communication signal relay and other operations.

"Thanks to its capability to conduct very long endurance flights in near space, the drone can essentially become a substitute for satellites," a Chinese aerospace expert said. Satellite services are not always available due to the limited number of satellites and relatively fixed schedules of overhead passes. In time-sensitive missions, near-space drones can offset these disadvantages, the expert said, noting that satellite services could also be damaged in wartime, so near-space drones could replace them in this occasion.

The successful first flight of the Qimingxing-50 lays a solid foundation for the development of key technologies in the country's new energy field, the composite (复合的) material field, which will enhance China's ability to perform tasks in near space and over far oceans. AVIC will seize the opportunity to increase investment and speed up the development of large solar-powered unmanned aircraft.
