1 . So the Columbia researchers came up with a system called Easy Secure Photos (ESP), which they presented at a recent conference. “We wanted to see if we could make it possible to encrypt data while using existing services,” says computer scientist Jason Nieh, one of the developers of ESP. “Everyone wants to stay with Google Photos and not have to register on a new encrypted-image cloud storage service.”

2 . Aside from being beautiful and promoting growth, the team observed that due to these lights, they needed to use 50 percent less pesticides (杀虫剂) on the crop. This is because this specific recipe of lights activated the defense system of the plants. And as it works on all crops, not just leeks, Roosegaarde foresees a way to reduce the use of pesticides on many other plants. And his project will soon be touring 40 countries, and sending its dancing lights across the world.

3 . Companies which sell liquids like drinks or shampoo rely on bottles for their packaging. Usually these bottles are made of plastic or glass. But as customers have become more concerned about the environment, many companies have begun working to develop paper bottles.

Paper bottles are easy to recycle. They also weigh less than glass or plastic, meaning they’ll require less energy to produce and to move around. They’re usually made from wood pulp (纸浆), which is pressed into a mold (模具) to create the bottle shape. Since paper is soft and easy to mold, companies can design their bottles to take almost any shape they choose.

6 . On Wednesday, 16-year-old Aava Murto took over for a day as prime minister of Finland. The move was part of an international effort called “Girls Takeover”, designed to bring attention to the rights of girls. Finland’s prime minister, Sanna Marin, handed over the position to Aava and showed her how things worked. Though Aava didn’t make any laws, she did meet with politicians, speak to reporters, and give a speech.

7 . Jane Goodall began observing chimpanzees in 1960 at Gombe Stream Game Reserve in what is now Tanzania, but her first study of animal behavior took place some 20 years earlier, when she, at 5 years old, spent several hours in a henhouse, waiting to see how a hen laid an egg.

That curiosity helped drive Goodall to become one of the most famous scientists of the 20th century. Her evolution from an innocent child to a “global icon (偶像)” is documented in “Becoming Jane”, an exhibit in Washington, D.C. through September 7. After that, it heads to the Natural History Museum of Los Angeles County.

10 . During an interview for one of my books, my interviewer said something I still think about often. Annoyed by the level of distraction (干扰) in his open office, he said, “That’s why I have a membership at the coworking space across the street — so I can focus. ” His comment struck me as strange. After all, coworking spaces also typically use an open office layout (布局). But I recently came across a study that shows why his approach works.

Why does the interviewer prefer a coworking space?
