3 . Winners of the Broadcom MASTERS
Girls took the top prizes at the Broadcom MASTERS, a science competition for middle school students.
Alaina Gassler
Alaina won the $25,000 Samueli Foundation Prize for the project of reducing blind spots in cars. She was inspired to solve this issue by her mother who didn’t like driving her vehicle because its large A-pillar (A柱) design made her feel in danger. “I started to think about how blind spots were a huge problem in all cars,” said Alaina. So she worked on and solved it.
Sidor Clare
Sidor won the $10,000 Marconi/Samueli Award for Innovation, an honor made by Samueli’s generous donation of his 2012 Marconi Society Prize Award. She developed bricks that could one day be made on Mars, so that humans wouldn’t be required to carry building materials with them in order to build there.
Alexis MacAvoy
Alexis won the $10,000 Robert Wood Johnson Foundation Award for Health Advancement, which recognized the student whose work and performance showed the most promise in health-related fields and demonstrated an understanding of the many social factors that affect health. She designed a water filter (过滤器) by using carbon to remove heavy metals from water.
Rachel Bergey
Rachel won the $10,000 Lemelson Award for Invention, awarded by The Lemelson Foundation to a young inventor creating promising solutions to real-world problems. She developed a trap made of tinfoil (锡纸) and netting for the spotted lanternfly, an invasive species causing damage to trees.

4 . Tian Wangui and his wife Lu Min are villagers in Qiantian Village, Liaoning Province. They began planting trees over forty years ago. With their hard work, the two barren (贫瘠的) mountains are covered by trees now.
After leaving the army in the 1980s, Tian got back home and began planting fruit trees on the hills. In 1982, the couple got the contract rights (承包经营权) of two mountains. At first, they planted some young fruit trees on part of the land. In order to water them, they had to carry water up to the top of the mountains many times a day by themselves.
Now, the two mountains are covered by more than 50,000 trees of over 20 kinds. More than 2,000 birds live in the trees in the mountains.
“We cared for the mountains and trees as we cared for our children,” said Lu. “Even as we grow old, our children will protect the woods, watch over the birds and keep our dream alive.”
