With a wide smile on her face, 15-year-old Sirin eagerly rushed to her mom to show off her new painting. But Mom raised her eyebrows with eyes wide open, and spoke impatiently, “No time, baby. Right now I am busy with an important talk. Just wait for some time, OK?”

Holding her oil painting, she frowned (皱眉),and then searched for her dad. “Dad, see what I have done,” Sirin exclaimed cheerfully. Her dad turned around while adjusting his tie, grinned at her, and showed his thumbs up!

Immediately, Sirin replied angrily, “Dad, you haven’t seen it yet.”

He smiled at her saying, “No time, baby. I will see it later.” He just patted her back lovingly, kissed her forehead, and rushed for his office.

She was not a kid to be pleased with simple gesture or smile. She stood there for a few seconds, and then stormed off to her own bedroom. Hot air was blowing from her nostrils (鼻孔) ; her face turned into apple red. She threw the painting on the table, slammed the door and threw herself on her bed.

“Why is everybody so busy?” She recalled thousands of incidents that hurt her in preschool, middle school and even in high school too! She assumed at least her own family members would give some values to her thoughts, but they were no exception. Unconsciously, her eyes were filled with tears.

The knocking sound on the door put a sudden stop to her thought. Her mom was calling her for dinner. Sirin deliberately (故意地) came late to join them. She kept silent and didn’t look at anyone, scratching the table mat with her nail. Her mom was puzzled at the unusual behavior. Suddenly the morning incident came to mind. Softly, she asked, “ Honey, did I do anything wrong? ”

At this very moment, Sirin could no longer resist her anger.

When back from school the next day, Sirin was surprised to see her beautifully-decorated paining on the wall.

2 . Endangered polar bears are breeding (繁殖) with grizzly bears (灰熊), creating “pizzly” bears, which is being driven by climate change, scientists say.

As the world warms and Arctic sea ice thins, starving polar bears are being forced ever further south, where they meet grizzlies, whose ranges are expanding northwards. And with that growing contact between the two come increasing hybrids (杂交种).

With characteristics that could give the hybrids an advantage in warming northern habitats, some scientists guess that they could be here to stay. “Usually, hybrids aren’t better suited to their environments than their parents, but these hybrids are able to search for a broader range of food sources,” Larisa DeSantis, an associate professor of biological sciences at Vanderbilt University, told Live Science.

The rise of “pizzly” bears appears with polar bears’ decline: their numbers are estimated to decrease by more than 30% in the next 30 years. This sudden fall is linked partly to “pizzly” bears taking up polar bears’ ranges, where they outcompete them, but also to polar bears’ highly specialized diets.

“Polar bears mainly consumed soft foods even during the Medieval Warm Period, a previous period of rapid warming,” DeSantis said, referring to fat meals such as seals. “Although all of these starving polar bears are trying to find alternative food sources, like seabird eggs, it could be a tipping point for their survival.” Actually, the calories they gain from these sources do not balance out those they burn from searching for them. This could result in a habitat ready for the hybrids to move in and take over, leading to a loss in biodiversity if polar bears are replaced.

“We’re having massive impacts with climate change on species,” DeSantis said. “The polar bear is telling us how bad things are. In some sense, “pizzly” bears could be a sad but necessary compromise given current warming trends.”

5 . When given the choice, about 85% of people say they would not want to know about some negative event far in the future. Yet recently millions around the globe have downloaded FaceApp, which allows users to see how they might age in real life.

Many had fun with joking that they love the FaceApp old filter. Beneath the humor is a serious subject: How do we learn to relate to our future selves? It’s important that we try to because it could help strengthen the long-term decisions that we make. However, we often fail to make sacrifices for the grayer versions of ourselves.

More than half of the respondents in a recent survey of 2,800 Americans said they rarely or never thought about what their lives might be like 30 years from now. This isn’t surprising, since most of us are firmly rooted in the present and thinking about the distant future can seem like a distant priority (优先). My ongoing research might also offer an explanation: We tend to think about our future selves as if they are someone different from who we are today. In an effort to narrow these empathy (共情) gaps, my research workmates and I have tried to humanize people’s future selves in the same way others have tried to humanize charity receivers. Given that a photograph of one hungry child can spark emotional reactions, and cause viewers to donate, we have presented participants with vivid images of their distant selves.

That seems helpful. In a recently completed project in Mexico, we found that exposure to future self-images led more people to contribute to their pensions. Despite this research, I’m skeptical that the app users will suddenly increase their pension contributions and care about their health. The silly app isn’t paired with an immediate opportunity to change any of these things.

The lesson from FaceApp shouldn’t be that we need to marry hi-tech visuals with savings for retirement. The lesson, then, lakes the form of a question: What more can be done to urge us to think about, care for who we will one day become?
