1 . To reduce coffee cup waste, Cup Club is already replacing millions of takeaway cups in the UK, while Recup in Germany, has performed a deposit system that simply adds a small extra fee to any coffee cup which is returned to the buyer after the cup is deposited in any registered collection point.

2 . Bennett, 57, held on through 60 tomorrows, far longer than any previous patient who’d received a heart from another species. His remarkable run offered new hope that such procedures, known as xenotransplantation (异种移植), could help relieve the shortage of replacement organs, saving thousands of lives each year.

3 . But Oreos don’t attract you with taste alone; scents have a huge impact on the eating experience. When you bite into an Oreo, chemicals in the cookie release odor ants into the air inside your mouth. These scents flow to your nasal cavity (鼻腔), where they interact with smell receptors (感受器) and enter your brain’s decoding (解码) process. Your brain is likely to find those smells delightful, says Charles Spence, a professor of experimental psychology at the UK’s University of Oxford. Spence says chocolate and vanilla are two of the world’s most liked smells.

4 . At the end of each day, the participants showed high activity in a brain area called the midbrain. The scientists were interested in two, small areas within it. Both areas produce dopamine, a chemical that is important in craving and rewards. The two areas activated when hungry participants saw pictures of tasty pizza or juicy hamburgers. After the volunteers had been isolated, those brain areas became active when they saw social activities they missed. It might be playing sports or chatting with friends.

5 . Regulatory limits for how much PFAS food packaging should contain can vary greatly. For instance, a new law in California set the limit at less than 100 ppm. “Compared to America, Denmark sets a much lower regulatory limit of 20 ppm with great success,” said Xenia Trier, an expert at the European Environment Agency. “It does work to set limits and enforce them. PFAS do migrate from the paper into the food. Even though it was not 100%, we still saw considerable transmission. In general, transmission from packaging to food is increased as the temperature of the food rises. It is the same with the time spent in wrapping materials.” Trier told NBS, one of the major American mass-media companies.

6 . A 2010 law had already banned smartphones during “all teaching activity” in France. But the new rules say smartphones and tablets are not allowed even during breaks. Students who bring these digital devices to school have to keep them in their backpacks and turned off. If they want to call their parents, schools will help. However, the new law doesn’t forbid students to turn to them during extra-curricular activities. It also makes an exception for disabled students.

8 . Starting a band across multiple time zones proved to be tricky. Shaky Wi-Fi and other technical difficulties meant they were often out of sync. And being even half a second off from one another wrecked their sound. To fix this, they created a sort of musical assembly line. Baltimore Paul and Rotterdam Paul wrote and recorded a basic track, then e-mailed it to Manchester Paul.

9 . How long we stay on the clock and how we spend that time are under careful examination in many workplaces. The young banker who eats lunch at his desk is probably seen as a go-getter, while his colleagues who chat over a relaxed conference-room meal get dirty looks from the corner office. “People from cultures that value relationships more than ours does are shocked by the thought of eating alone in front of a computer”, says Art Markman, a professor of psychology at the University of Texas, Austin. Social interaction has been shown to lift mood (情绪) and get people thinking in new directions and in ways that could help improve any post-lunch effort.

10 . Allcove provides fully staffed safe spaces for teens and young adults to discuss and deal with their health, both mental and physical. Dr. Steven Adelsheim, a psychiatrist, who created the Allcove in 2014, said, “There is a crying need in the U.S. to reach kids with early intervention and help.” Sometimes a kid may come in with a physical complaint, and only after a few visits is the mental suffering brought out into the open. When that happens, Alcove can make a “warm handoff” to a mental health specialist onsite. Success, say Adelsheim and Cox, would mean the establishment of hundreds of Allcove centers up and down the state and, eventually, around the country.
