4 . By the end of the century, if not sooner, the world’s oceans will be bluer and greener thanks to a warming climate, according to a new study.
At the heart of the phenomenon lie tiny marine microorganisms (海洋微生物) called phytoplankton. Because of the way light reflects off the organisms, these phytoplankton create colourful patterns at the ocean surface. Ocean colour varies from green to blue, depending on the type and concentration of phytoplankton. Climate change will fuel the growth of phytoplankton in some areas, while reducing it in other spots, leading to changes in the ocean’s appearance.
Phytoplankton live at the ocean surface, where they pull carbon dioxide (二氧化碳) into the ocean while giving off oxygen. When these organisms die, they bury carbon in the deep ocean, an important process that helps to regulate the global climate. But phytoplankton are vulnerable to the ocean’s warming trend. Warming changes key characteristics of the ocean and can affect phytoplankton growth, since they need not only sunlight and carbon dioxide to grow, but also nutrients.
Stephanie Dutkiewicz, a scientist in MIT’s Center for Global Change Science, built a climate model thatprojectschanges to the oceans throughout the century. In a world that warms up by 39C, it found that multiple changes to the colour of the oceans would occur. The model projects that currently blue areas with little phytoplankton could become even bluer. But in some waters, such as those of the Arctic, a warming will make conditions riper for phytoplankton, and these areas will turn greener.” Not only are the quantities of phytoplankton in the ocean changing,” she said, “but the type of phytoplankton is changing.”
And why does that matter? Phytoplankton are the base of the food web. If certain kinds begin to disappear from the ocean, Dutkiewicz said, “it will change the type of fish that will be able to survive.” Those kinds of changes could affect the food chain.
Whatever colour changes the ocean experiences in the coming decades will probably be too gradual and unnoticeable, but they could mean significant changes. “It’ll be a while before we can statistically show that the changes are happening because of climate change,” Dutkiewicz said, “ but the change in the colour of the ocean will be one of the early warning signals that we really have changed our planet.”

5 . One ambitious high school student knew exactly how to show his family that he got accepted into his dream college—by surprising them on Christmas Day.
Barrington Lincoln, class president at Lutheran High School North in Ferguson, got accepted into Morehouse College in Atlanta back on Dec. 15. But for months, he knew he wanted to make the news known in a big way to his mother and aunt, Lincoln told ABC News. “I thought of the surprise in October,” he said, adding that once he got accepted, he would purchase two school T-shits from Morehouse’s online store.
On Christmas Day, in a now video on Twitter, Lincoln, 17, gifted his mom Lisa McDonald and his aunt Shirley Gray the T-shirts with the school’s name on it. When the two sisters opened the gifts, they had no idea what they meant.
In the video, Lincoln nudges (用肘轻推) his family, “You know what that means right? I got in!” While McDonald falls heavily on the couch in delight, Gray asks, “You’ve been holding out on us?”
“I didn’t expect anything like that,” McDonald told ABC News. “It’s so satisfying to see him get the return on his studying.” “He always wanted to be the first in line and help everybody stay in line,” his mother added.
McDonald said it’s especially sweet since she had to wok an extra job to afford his private school after his father, a former Marine, passed away in 2015. Lincoln was only 15.

6 . If you want to convince the boss you deserve a pay rise or promotion, the solution could be simple --- eat the same food as they do. Psychologists have discovered managers are much more likely to instantly trust us if we choose the same dishes as them.
During experiments, discussions over wages and work conditions were much more successful if both sides chose to snack on the same treats. And shoppers were much more likely to buy a product advertised on TV by someone eating a similar food to them at the time.
The reason is thought to be the so–called similarity attraction theory --- where people tend to like others who have similar tastes or habits to themselves. But this is believed to be one of the first studies highlighting the role of food in this relationship. Researchers at Chicago University in the US conducted a series of experiments to examine food’s role in earning trust.
In a test, participants were told to watch TV --- where someone pretending to be a member of the public praised a certain product. The volunteers were given Kit Kat bars to nibble, while the TV people ate either a Kit Kat or grapes as they talked.
The results showed viewers were much more likely to express an interest in buying the product if the TV showed the other person eating a Kit Kat too. The researchers added, “Although similarity in food consumption is not a sign of whether two people will get along, we find consumers treat this as such. They feel more trusting of those who consume as they do. It means people can immediately begin to feel friendship and develop a bond, leading to smoother transactions from the start.”
Harley Street psychologist Dr. Lucy Atcheson said it was already known that wearing similar clothes could instantly create trust. But this was the first report that food had the same effect. She said, “This is really interesting. It makes sense as people feel they have common ground and can trust the other person. That means negotiations are more likely to be successful.”
