1 . Maria and her parents moved to the US from Brazil one year before the pandemic (流行病). Better education opportunities lay ahead, and they were excited to get Maria into an American high school to prepare for college.

Each parent got a job, and Maria started studying. She also signed up for a service club because she wanted to meet people, practice her English and be a part of the community. “I love to serve,” Maria says. “I think it is my thank-you for the opportunities I have.”

She worked at the local food bank with other kids of her age, organizing bags for families who were having a hard time making ends meet. But when the pandemic hit, she found herself at the food bank for another reason: to bring home groceries to her parents. “We were all shocked when my mother lost her job. My friends at the food bank got me through it,” Maria said.

Luckily, her father kept his job. And with classes moving online, Maria was able to secure a full-time job and do her class work at night. Three of her courses were college prep classes that demanded a lot of work. During her senior year, Maria worked 40-hour weeks and studied even more. Yet, in her spare time, she packed food bags for others before taking hers home.

Just before graduation, Maria came into the food bank. One of the volunteers started getting a bag ready for her. “I don’t need one today,” Maria said. “My mother got a job. I’m here to help.”

Maria supported her family for eight months. She graduated on time and got scholarship offers from three different colleges. She moved to part-time work and has completed her first semester of college.

Wherever we go, we are surrounded by history. Across the globe, cultural heritage is passed down through the generations. It is in the buildings and structures around us. It is in the arts and artifacts (手工艺品) we treasure. It lives in the languages we speak and the stories we tell. But today, it is under attack as never before. Not only are the damages of time threatening our cultural heritage, but conflicts, climate change, globalization and tourism are all exacting a heavy price. Technology is now the most essential weapon in the battle. Here's how technology is preserving our cultural heritage.

As you can imagine, creating the replicas (复制品) via crowd sourced 2D images is extremely time-consuming. Increasingly, artificial intelligence (AI) algorithms (算法) are being used to do all the required sourcing, allowing millions of images to be stored in a matter of hours.   AI will also make restoration and preservation of existing cultural heritage far easier and vastly superior to previous methods.

Virtual reality (VR) technology will play a leading role in preserving our cultural heritage in the coming years. Many of the most important sites and architecture are extremely fragile. Human interaction with these locations is doing a great deal of harm. Wastes accumulate everywhere, causing enormous problems. As more cultural heritage sites and objects are digitally mapped and recorded, VR technology will increasingly become the way that people experience them. We'll all eventually be able to walk through places, look at (and touch!) artifacts and works of art without ever seeing them with our own eyes.

Finally, our cultural heritage will be preserved via technology. Efforts in research, innovation, data sharing and project work will help promote and preserve the cultural heritage of countries all across the world.

10 . In a remote corner of Brazil's Amazon tropical（热带的）rainforest, researchers have spent decades catching and measuring birds. Over 40 years, dozens of Amazonian bird species have declined in mass（质量）. Many species have lost nearly 2% of their average body weight each decade, researchers report November 12 in Science Advances. Some species have grown longer wings. The changes could help birds stay cool in a hotter, more changeable climate, the researchers say.

"Climate change isn't something of the future. It has been happening and has effects we haven't thought of," says Ben Winger, an ornithologist（鸟类专家）at the University of Michigan, who wasn't involved in the research but has documented similar shrinkage（缩水）in migratory birds.

To see if non-migratory birds have also been shrinking, Jirinec and colleagues analyzed data collected from 1979 to 2019 in a remote region in the Amazon that spans 43km. The data include over 11,000 individual birds of 77 species as well as climate for the region.

All species declined in mass over this period, the researchers found. Species lost from about 0.1% to nearly 2% of their average body weight each decade. The motmot, for example, shrunk from 133g to about 127g over the study period.

These changes coincided with an overall increase in the average temperature of 1℃ in the wet season and 1.65%℃ in the dry season. Birds' mass decreased the most in a year or two after especially hot and dry seasons, which tracks with the idea that birds are getting smaller to deal with heat stress.

Wing length also grew for 61 species, with a maximum increase of 1% per decade. Jirinec thinks longer wings make for more efficient, and thus cooler, fliers.

"The Amazon rainforest is mysterious, remote and full of biodiversity," Jirined says. "This study suggests that even in places like this, far removed from civilization, you can see signatures of climate change."
