Could the device, smartphone or PC，which you're using affect the moral decisions you make when using it? To test it, researchers presented multiple dilemmas to a sample set of 1,010 people. The participants were assigned a device at random.

    One case of the questions participants were asked is the classic “trolley (有轨电车) problem”: A runaway trolley is headed towards five people tied up on a set of train tracks. You can do nothing, resulting in the deaths of five people, or push a man off a bridge, which will stop the trolley. The practical response is to kill one man to save five lives, which 33.5 percent of smartphone users chose, compared to 22.3 percent of PC users.

    “What we found in our study is that when people used a smartphone to view classic moral problems, they were more likely to make more unemotional, reasonable decisions when presented with a highly emotional dilemma, ”Dr Albert Barque-Duran, the lead author of the study, told City, University of London. “This could be due to the increased time pressure often present with smartphones and also the increased psychological distance which can occur when we use such devices compared to PCs.”

    As for why the researchers started this study, Dr Barque-Duran noted, “Due to the fact that our social lives, work and even shopping take place online, it is important to think about how the contexts where we typically face moral decisions and are asked to engage in moral behavior have changed, and the impact this could have on the hundreds of millions of people who use such devices daily.” It's clear that we need more research on how our devices affect our moral decision making because we're using screens at an ever-increasing rate.

    A group of scientists is gathering today in the U. K. to discuss a thick piece of ice that's cracking in Antarctica, which is of the size of Delaware.

    The ice shelf is called Larsen C, and it now has a 90-mile crack running through it. The big rift (裂缝) is slicing the ice shelf from top to bottom. But this is not just another sad climate change story. It's more complicated. "A lot of things are going on deep inside the ice," says Adrian Luckman, a glaciologist.

    Luckman says climate change is certainly influencing this region. Larsen C used to have two neighbors to the north, Larsen A and Larsen B. As the air and water warmed, those ice shelves started melting and then disappeared in 1995 and 2002. But the crack in Larsen C seems to have happened on its own, for different reasons.

    Larsen C has many cracks. All ice shelves do. This particular crack has been around since at least the 1960s. The unusual part is that in 2014, this crack — and only this crack — started growing quickly. Why?

    "Well, that is a little bit of a mystery and that's why it drew itself to our attention," says Luckman. One puzzling aspect is how it managed to cut through areas of softer ice that bind (连接) the ice from neighboring glaciers into one giant sheet. Starting in 2014, that soft ice did very little to slow down this rift.

    Scientists are split on how important this crack is for the stability of the whole ice shelf. Some say if this giant section breaks off, it won't make a difference. Others disagree.

    "Ice shelves are the gates of Antarctica in a way, and the gatekeepers of Antarctica. The ice shelves are already floating, so if they fall apart it does not immediately affect sea levels. It's what they hold back -water from all the inland glaciers — that could be problematic. If all the water packed in those glaciers made their way to the sea, it could significantly raise global sea levels," says Ala Khazendar, a geophysicist.

    The strand bookstore is a New York Institution, and Fred Bass was a part of it almost from the moment he was born until the day he died. Every day, dozens of sellers arrive armed with piles of books, and every day thousands of buyers browse through the 18 miles of shelving, squeezing through narrow, dark aisles towered over by high, cramped shelves.

    Film studios wanting a line of books for a backdrop rent them from the Strand by the foot; interior designers looking for books with the same color spine will order a job lot; and hosts wishing to impress dinner guests will order the latest tomes(巨著) to replace on their coffee tables. Some even might be read.

    "You never know what someone is going to walk in with," Bass told The Villager magazine in 2010, adding that there was nothing he loved more than the "treasure hunt". Many books came from critics keen to add to their income by offloading review copies, they came from large estates, fellow bookshops and even publishers quietly offloading surplus(过剩的) stock. One visitor spoke of Bass as a character who could have come from a book. "I remember sensing in Bass, beyond a slightly gruff look, a man of great passion, a man who knew the innumerable and shifting current of the book trade the way that an old sailor knows the changeable sea," wrote Tom Vanderbilt in the New York Review of Books.

    Bass himself took a kind, almost paternalistic(家长式的) approach to the business. Some employees remained with him for decades.  When Greg Farr, a dissatisfied member of staff, published a novel that was critical of the store's management and the unions he still had his job, furthermore, the Strand sold his book.

Fred Bass was born in Manhattan in 1928, the year after his father, Benjamin, a Lithuanian immigrant, founded the Strand bookstore on Fourth Avenue, which was then known as "Book Row". His mother, Shirley, a Polish immigrant, died from cancer when Fred was six. His father remarried, to Esther, a bookkeeper who was involved in various civil rights causes.

    As a child young Fred swept the floors and by 13 he was working behind the counter on Saturdays. He recalled going on buying trips with his father and hauling back bundles of books on the subway, all tied with rope that cut into his hands. The family lived in the Bronx and young Fred studied English at Brooklyn College in the mornings and worked in the shop in the afternoons. His only extended period of time away was two year' service with the US armed forces, but even then he used his leave from the Korean War to work at the shop. In 1957, a year after taking over the business, Bass moved the store from Fourth Avenue to the corner of 12th Street and Broadway, where it stands to this day.

In 1952, Bass, who could eventually afford to purchase an apartment in Trump Tower, married Patricia Miller. They had a son, Stephen, who died in 2001, and a daughter, Nancy, who married Ron Wyden, a senator from Oregon. Since her teens she has worked with her father, developing the store, remodeling the space and adding air conditioning ("I hated it," said Bass). Since 1986 the Strand has run a "Books by the Foot" department, which creates custom book collections based on readers' literary tastes or preferred colors.

    In 1996, after seven decades as tenants(房客), the Bass family bought their building for $8.2 million. Until then they had negotiated the lease with their landlord at the nearby Knickerbock Bar and Grill; now Bass had to deal with himself." When I want to negotiate my own lease I have go to the bar myself", he joked. Even in his late eighties Bass was making buying trips, though no longer by subway.

Time and the Internet have not been kind to booksellers. "Book Row" is now only the Strand, which itself has been redesigned to be more "userfriendly". T-shirts, postcards, fridge magnets and other gifts now account for about 15 per cent of the Strand's turnover. Satellite stores have been set up and new books have joined the traditional secondhand commodities. "I make less money, "Bass said," but it's a little bit more scientific".

    Perhaps the most unusual part of management at the Strand book store was the book quiz­matching authors and title­that job applicants since the 1970 have been required to take.

    February has long been a month of romance. With the sweet smell of roses in the air, romantic films hit cinemas and love stories fill newspapers and magazines.

    On the 14th day, it is customary for a boy to take his girlfriend out to dinner, buy her flowers and chocolates, write poems, sing to her or even spell out her name with rose petals!

    This is the scene that greets you on Valentine's Day, named after Valentine who was a priest in third century Rome. When the emperor decided that single men made better soldiers than those with wives, he banned marriage.

    But Valentine continued to perform marriage ceremonies for young lovers in secret. When his actions were discovered, the emperor had him put to death.

    While in prison, it is said that Valentine fell in love with the daughter of his prison guard. Before his death, he wrote her a letter, which he signed "From your Valentine", an expression that is still in use today.

    Valentine died for what he believed in and so was made a Saint, as well as becoming one of history's most romantic figures.

    Nowadays, Valentine's Day wins the same popularity among Chinese young people. It is a time when students "don't want to be alone" according to Gao Shunjie, a student reporter for 21st Century Teens in Jinling High School, Nanjing. Some of her classmates are planning to make Valentine's cards for parents, teachers and friends. Others want to hold parties at which they will exchange small gifts and eat heart shaped cakes. The idea is to have fun and encourage people to share in the spirit of St Valentine.

A team of biologists (生物学家) recently studied wildlife in the forests of northern Ecuador. While doing so, they made a surprising discovery: a Mindo harlequin toad (明多斑足蟾). The creature hadn't been seen alive in 30 years. The scientists couldn't believe their eyes. "It took our brains a while to believe it was a Mindo harlequin toad," says Melissa Costales, a conservation biologist from University of New Brunswick.

The Mindo harlequin is the latest harlequin toad species "to come back from the dead," says Costales. Since 2003, eight others have been found, three of them in Ecuador.

Until recently, 13 of the 25 species of harlequin toads in Ecuador had gone unseen since the 1980s or early 1990s. Scientists thought most of them had been killed by a disease called chytrid (壶菌). This illness is especially harmful to the harlequin toad.

Costales says the Mindo harlequin toad may have developed a resistance (抵抗力) to the disease. That would explain the toad's reappearance. And it could spell good news for other harlequins. Since discovering the first one, Costales's team has found five more. They were all tested for chytrid. None had the disease. But that doesn't mean the survival of the species is guaranteed (保证), Costales says. The harlequin toad is still endangered.

Costales is developing a conservation plan with a zoology museum in Ecuador. She wants to make sure the Mindo harlequin toad doesn't fall back into extinction. "Each rediscovery gives us a second chance to develop better conservation plans," she says. "Not every day do we have the chance to rediscover a species that we believed to be extinct."

Standing on the South Pole at the start of the year with the wind blowing across the Antarctic, travel blogger Johnny Ward felt a wave of relief.

Just a week before, in early January 2024, he'd struggled through snow and ice to climb to the top of the Vinson Massif, Antarctica's highest peak. Years before, in 2017, he'd become the first Irish person to visit every country in the world.

Now, after decades of traveling and mountaineering, Ward could claim another world first—the Ultimate Explorer's Grand Slam (大满贯), which involves reaching the highest peak on every continent, and visiting both the North and South Poles in addition to visiting every country.

"I feel relieved," Ward recalled as he slowly made his way back to his home in Thailand after climbing to the top of the Vinson Massif and then setting foot on the South Pole. "But also I'm aware I'm a normal guy, not a world-class athlete, so I guess it was more about resilience and determination more than any ability. Although I met with lots of barriers, I overcame them one by one."

Ward had previously devoted a decade of his life, between 2007 and 2017, to visiting every country in the world. The incredible journey saw him hitchhike (搭便车) a ride on a container ship from Oman to Socotra in Yemen, travel overland from Cairo to Cape Town and travel from South Korea to Australia by bus and boat.

"It had been a huge life goal, over a decade of my life, and then when I finished that I was aimless and had no idea what to do next," he said. "I started eating badly, drinking too much, putting on weight and I ignored my business."

Ward decided that the best way to overcome this was to challenge himself again. He began running ultramarathons (超级马拉松) and climbing mountains, and soon found that with extreme purpose and direction, he was back to loving life again.

So where will Ward go next? Space? The bottom of the Mariana Trench, the deepest point of the ocean? "All good things come after suffering, and I want to share that with people. So that's the next plan," he said.
