For years, scientist and others concerned about climate change have been talking about the need for carbon capture and storage(CCS).

    That is the term for removing carbon dioxide from, say, a coal-burning power plant's smokestack and pumping it deep underground to keep it out of the atmosphere, where it would otherwise contribute to global warming.

    However, currently, only one power plant in Canada captures and stores carbon on a commercial scale (and it has been having problems). Among the concerns about storage is that carbon dioxide in gaseous or liquid form that is pumped underground might escape back to the atmosphere. So storage sites would have to be monitored, potentially for decades or centuries.

    But scientists at Lamont-Doherty Earth Observatory at Columbia University and other institutions have come up with a different way to store CO₂ reacts with the rock to form a mineral call calcite(方解石). By turning the gas into stone, scientists can lock it away permanently. Volcanic rocks called basalts(玄武岩) are excellent for his process, because they are rich in calcium, magnesium and iron, which react with CO₂.

    The project called CarbFix started in Iceland, 2012, when the scientists pumped about 250 tons of carbon dioxide, mixed with water, about 1,500 feet down into porous basalt. Early sings were encouraging: The scientists found that about 95 percent of the carbon dioxide was changed into calcite. And even more importantly, they wrote, the change happened relatively quickly—in less than two years.

    “It's beyond all our expectations,” said Edda Aradottir, who manages the project. Rapid change of the CO₂ means that a project would probably have to be monitored for a far shorter time than a more conventional storage site.

    There are still concerns about whether the technology will prove useful in the fight against global warming. For one thing, it would have to be scaled up enormously. For another, a lot of water is needed—25 tons of it for every ton of CO₂—along with the right kind of rock.

    But the researchers say that there is enough porous basaltic rock in Iceland, including in the ocean floors and along the margins of continents. And sitting a storage project in or near the ocean could potentially solve the water problem at the same time, as the researchers say seawater would work just fine.

    Taylor Swift was born on December 13, 1989, in Wyomissing, Pennsylvania. Swift's family ran a farm. “I had her sitting on a small horse when she was nine months old,” said Swift's mother. “If my dream had gone well, she'd be in a horse show right now.” The only obvious forerunner (先驱) of Swift's musical talent was her grandmother, an opera singer.

    That talent showed itself early: when the family went to see a Disney musical film, Swift would come out of the theater singing all the songs correctly. At the age of 11, she sang “The Star-Spangled Banner” at a Philadelphia 76ers game. The experiences during her pre-teen years encouraged the creativity to go with Swift's talent. As a child, she attended the academically competitive Wyndcroft School in Pottstown, but then switched to public schools in Wyomissing. Although it was her hometown, she didn't know any of her classmates, and she was terrified. Swift began to understand the storytelling feature of country songs, and put her feelings into songs of her own.

    One of her future hits, “The Outside”, was written when she was only 12. “I wrote that about the scariest feeling I've ever felt: going to school, looking at those faces, and not knowing who you're gonna talk to that day,” she said. “In the music, I could never feel the kind of rejection (拒绝) that I felt in middle school.” Swift's parents quickly realized that they had someone special on their hands. They sold their farm when she was 13 and moved the family to Hendersonville, Tennessee.

    Swift had the ability, above all, to put feelings into words with accuracy (准确) far beyond her years. In “Our Song” she wrote, “Our song is the slamming screen door, going out late, tapping on your window.” In the summer of 2006, “Tim McGraw” came out, and almost from the beginning the 16-year-old Taylor Swift was a star.

    Dutch beachcomber (海滩拾荒者) Wim Kruiswijk has accumulated a collection of 1,200 messages-in-bottles over the course of nearly 4 decades and has responded to almost all of them,

    68-year-old Kruiswijk says that his unusual hobby began in 1983 when he found three drift bottles (漂流瓶) on his local beach, each containing letters and return addresses. He wrote to all three addresses and was surprised to receive responses from each one. It was this experience that aroused his interest in hunting and collecting messages in bottles, and he hasn't stopped looking for them since.

"I find my messages in bottles on the beach of Zandvoort, where I live, and on the Dutch Islands," Kruiswijk recently told Great Big Story. "Messages in bottles is slow mail. It takes you days, or weeks, or months to find a bottle. "

In the early years, Kruiswijk would find as many as 50 bottles a year, but since 2000 that has slowed to around 20-30 finds, mainly due to beach cleaning efforts. He believes that the rise of the Internet has also played a role in the diminishing number of messages in bottles, telling Dutch newssite PZC, "I used to get a response at half the bottle messages that I answered. Now that's less; many people want 'instant satisfaction'."

    Throwing a message in a bottle out into the sea is a longstanding human tradition dating back to the time of the Greek philosopher Theophrastus, about 310 BC，who used the bottles to study water currents. Scientists still apply the method to this day, as a means to help researchers develop ocean circulation maps, and to crowdsource scientific studies of ocean currents.

    In the past bottles have also been used to send distress messages from sailors in trouble. They also have been used for memorial tributes, or to send loved ones' ashes on a final journey. One of the more common uses though is just to send invitations out to prospective pen pals, a quaint notion in these modern times, but, as Kruiswijk so clearly shows, an effective one.

    Boomerang children who return to live with their parents after university can be good for families, leading to closer, more supportive relationships and increased contact between the generations, a study has found.

    The findings contradict research published earlier this year showing that returning adult children trigger a significant decline in their parents' quality of life and wellbeing.

    The young adults taking part in the study were “more positive than might have been expected” about moving back home – the shame is reduced as so many of their peers are in the same position, and they acknowledged the benefits of their parents' financial and emotional support. Daughters were happier than sons, often slipping back easily into teenage patterns of behaviour, the study found.

    Parents on the whole were more uncertain, expressing concern about the likely duration of the arrangement and how to manage it. But they acknowledged that things were different for graduates today, who leave university with huge debts and fewer job opportunities.

    The families featured in the study were middle-class and tended to view the achievement of adult independence for their children as a “family project”. Parents accepted that their children required support as university students and then as graduates returning home, as they tried to find jobs paying enough to enable them to move out and get on the housing ladder.

    “However,” the study says, “day-to-day tensions about the prospects of achieving different dimensions of independence, which in a few extreme cases came close to conflict, characterised the experience of a majority of parents and a little over half the graduates”.

    Areas of disagreement included chores, money and social life. While parents were keen to help, they also wanted different relationships from those they had with their own parents, and continuing to support their adult children allowed them to remain close.

    Before uploading a photo of ourselves to social media, chances are that we'll use an app to smooth our skin, make our eyes look bigger, and lips fuller. With a couple of taps on our mobile phone, we can get a quick fix and present the "best" version of ourselves to the world. However, the problem is, when we simply edit our imperfections away, we're also changing the way we look at ourselves.

    Last month, researchers published the article Selfies – Living in the Era of Filtered(过滤的) Photographs. The article analyzed photo editing apps' bad influences on people's self-respect and their possibility to cause appearance anxieties. The researchers also warned that such apps make it difficult to tell the difference between reality and fantasy. "These apps allow one to change his or her appearance in minutes and follow an unrealistic standard of beauty," the article reads.

    In the past, people may have compared their looks to those of famous persons. But for today's young people, beauty standards are most likely set by what they see on social media. "From birth, they are born into an age of social platforms where their feelings of self-worth can be based purely on the number of likes and followers that they have, which is linked to how good they look." British cosmetic doctor Tijion Esho told The Independent. This is why many young people suffer an identity trouble when it comes to appearance.

    "Now you've got this daily comparison of your real self to this fake self that you present on social media." Renee Engeln, a professor of psychology, told the HuffPost website. Engeln further pointed out that when people spend too much time making such comparisons, they may become "beauty sick" and find it difficult to accept what they actually look like. "Because between you and the world is a mirror, it's a mirror that travels with you everywhere. You can't seem to put it down." she told The Washington Post. So when we look in a real mirror, we shouldn't think to ourselves, "Do I look as good as myself in the filtered photos?" Instead, we should think, "I feel good; I have my health."

Perhaps you have seen them, those who fall asleep on the subway and then, somehow, wake up exactly at their stop. Perhaps you are one of them. How is this possible? We spoke to two doctors, who offered their insights about it.

It is possible that your body gets used to waking up at a certain point each time during your commute, said Dr. Marc I. Leavey, a primary-care specialist in Maryland. That holds especially true if you commute at the same time every day. This suggests that if you were to get on at a different time, or if the journey were delayed, your internal clock might not wake you up at your stop. It is an interesting theory, but Dr. Ronald Chervin, director of Michigan Medicine's Sleep Disorders Centers, does not fully buy it. He is skeptical that circadian rhythms can also explain why you wake up after a brief nap.

You are also likely to wake up for your particular stop because of an oral cue, such as the conductor stating the name of the subway stop over the public-address system. Such cues alert your brain that you have arrived, explained Dr Leavey. According to a study published in the Public Library of Science, during sleep, our brain reacts differently when we hear our own name and other people's names, noted Dr Chervin. This suggests that your brain does not turn off during sleep, which makes it possible to pick up on the announcement of your stop.

Another reasonable possibility: You may wake up at each stop, check if it is yours, and go back to sleep, all without having remembered it, added Dr. Chervin. He sees this in cases where patients are suffering from sleep apnea. They may wake up as many as 200 times during a single night, without having remembered a single instance. That's because they fall right back asleep before their brain has time to process their experience into long-term memory. Similarly, you could be waking up every time you hear a new stop called. But you just don't remember such instances even after you fully come awake for your stop—leading you to believe that you have slept the whole way through and miraculously woken up at the right time.
