1 . In the west of the city Seville in Spain, a sea of giant mirrors is reflecting the sun’s energy to provide “concentrated solar power (CSP)” while brightening the path to a new wave of green energy projects.

The 624 carefully positioned mirrors reflect the sun’s heat towards a 50-meter-tall central tower where it is concentrated and used to boil water into steam. The superheated steam is then used to turn a turbine (汽轮机) that can produce up to 11 megawatts of electricity—enough power for 6,000 homes—according to Solucar, the Spanish company that has built the power plant.

The Spanish tower, known as PS10, is the first stage of an ambitious development. By 2025 it is hoped that additional towers will create “a solar farm” with an output of 500 megawatts, which would be enough power for 180,000 homes, almost the entire population of nearby Seville.

CSP produces no greenhouse gases and the only pollution is visual. There is also the possibility that production can keep going around the clock-even when the sun has gone down. Solucar is currently testing technology at a plant near Granada that will pump 50 percent of the electricity generated in the day into the Spanish national grid (国家输电网), and use the other 50 percent to melt salt, which will then act as a kind of battery, storing the sun’s power. When dusk falls, the heat stored in the molten salt can be used to generate power through the night.

The Sahara, the world’s largest desert, has always been seen as a problem. But with large-scale CSP projects, suddenly all that empty space, with its year round clear skies and hot sun, has a value that could transform local economies. It could potentially turn Africa into an exporter of energy to power-hungry Europe.

2 . Greg Dailey closed his picture frame store due to the coronavirus pandemic (冠状病毒大流行), and his second job of delivering newspapers became his primary source of income.

Dailey’s grocery trips began when one of his elderly customers asked him for a favor. “Mrs. Ross called me on Wednesday before my store shutting down and asked if I could throw the newspaper closer to her house,” he tells Yahoo Life. “A couple of days later, I was standing in a grocery, and I called her and asked if she needed anything from a grocery. She was astonished. Moments later, she called me back and asked if I wouldn’t mind grabbing something from Mrs. Miller across the street.”

Soon, Dailey’s 800 customers found a note he wrote tucked in with their newspaper, offering his help. “And the next day I just decided, ‘You know, what? If there are two people that live within a hundred feet of each other having issues getting the essential things they need, I’m going to put out a note.’”

The words spread not only to his community but to surrounding ones. Since then, Dailey, with the help of his family, developed a system to keep track of the orders. To date, Dailey has made more than 600 trips to the grocery for his neighbors and delivered everything to their homes for free. “These last three months has changed my life… I get emotional because some of them have become really special to me,” he says.

Dailey reopened his frame store on June 15, and he promised to continue to help seniors not only with groceries but with anything else they need. He knows those he helps will remain a part of his life going forward.

“It’s moments like this, we need to step back and take a look in ourselves and realize that we can do more… and it’s something I live by,” Dailey says. “If you have the opportunity to do something nice for someone, just do it.”

3 . BOLTON SCHOOL SIXTH RORM GIRLS

2021-2022 HISTORICAL ASSOCIATION LECTURES

Historical Association branch meetings have been a regular feature in the Girl’s Division for the past six years. Each year, a series of seven lectures are delivered by a range of academics from different universities and research institutes. Attendees meet in the comfortable surroundings of the Sutcliffe Suite and enjoy a chat over tea and biscuits before and after the highly interesting and exciting lectures. Over the past years, attendees have enjoyed lectures on the American Civil War and Simon de Montfort. The branch welcomes pupils from a number of surrounding schools in particular at the Great Debate competition.

In order to allow for more time to adapt to ever changing circumstances with regards to COVID-19, the branch has decided to delay the start of the 2021 - 2022 season until January, 2022. There will be six lectures, running into June for the first time in the branch’s history.

While the branch has often provided comfort on cold winter nights, we do hope that members, new and old, will now join us as in the spring and summer of 2022. We hope to welcome lecturers who will be speaking about the Mayflower, the Jacobites and 17th Century Versailles. In the meantime, please follow@ boltonhistory on Twitter, or “Bolton Historical Association” on Facebook, for updates. Alternatively(或者), please speak to Mr. Owen, Head of History, in school.

7 . The Analysis of Friendship with Robin Dunbar

Friendship is the single most important thing that affects our psychological and our physical health and well-being.

In this online talk, Robin Dunbar will explain how our brains create friendships for us.

About the speaker:

Robin Dunbar is Professor of Evolutionary Psychology at the University of Oxford. He spent the first half of his career studying the social behavior of monkeys and antelopes in Africa, and the second half studying humans. He has published 400 science journal articles. Besides, he has contributed to many radio and TV science documentaries, and has written a dozen popular science books.
