1 . A study, published in European Heart Journal, is the first to assess how different movement patterns throughout the 24-hour day are linked to heart health.
In this study, British researchers analyzed data from six studies, involving 15,246 people from five countries, to see how movement behavior across the day is associated with heart health. Each participant used a wearable device, a key novelty, on their thighs (大腿) to measure their activities throughout the 24-hour day and had their heart health measured.
The researchers identified a series of behaviors that make up a typical 24-hour day, with time spent doing moderate-vigorous activity providing the most benefit to heart health, followed by light activity, standing and sleeping compared with the negative impact of sedentary (久坐) behavior. The team modeled what would happen if an individual changed various amounts of one behavior for another each day for a week, in order to estimate the effect on heart health for each scenario. When replacing sedentary behavior, as little as five minutes of moderate-vigorous activity had a noticeable effect on heart health.
Dr. Jo Blodgett, first author of the study, said, “The big takeaway from our research is that while small changes to how you move can have a positive effect on heart health, intensity of movement matters. The most beneficial change we observed was to replace sitting with moderate-vigorous activity, which could be a run, a brisk walk, or stair climbing, basically any activity that raises your heart rate and makes you breathe faster, even for a minute or two. ”
Dr. Jo Blodgett also pointed out that although time spent doing vigorous activity was the quickest way to improve heart health, there are ways to benefit for people of all abilities — it’s just that the lower the intensity of the activity, the longer the time is required to start having a reliable benefit. Using a standing desk for a few hours a day instead of a sitting desk, for example, is not only a change over a relatively large amount of time but is also one that could be combined into a working routine fairly easily as it does not require any time commitment.

3 . Where do you expect to see graffiti (涂鸦)? Probably not in a museum. Bristol Museum and Art Gallery, in the south-west of England, was the kind of place you went to see classical statues and stuffed animals in cases until the arrivals of the ‘Banksy Versus the Bristol Museum’ exhibition in 2009. The exhibition hosted more than 100 works by Banksy, one of the world’s most famous graffiti artists.
Banksy is a man of mystery (神秘). He hardly ever gives interviews and likes to be anonymous (匿名的). Nobody knows much about his life or his background but many people believe that his real name is either Robin Cunningham, Robert Banks or Robin Banks and that he was born in 1973 near Bristol.
Banksy’s questioned ‘street art’ includes paintings on live sheep and cows and graffiti on the huge wall put up to divide two areas. Brand Pitt spent over 82 million on a Bansky original. Banksy designed an album cover for the Britpop group Blur in 2003 but he has refused requests to do adverts for Nike. A year after the Bristol exhibition, Banksy made a film called Exit Through the Gift Shop. The film tells the story of a French street artist in America. Exit Through the Gift Shop received many positive reviews. Nobody knows if it was about a real artist or an invented character from Banksy’s imagination.
Bristol isn’t the only place in Britain to welcome graffiti. The DPM Park in Dundee, Scotland has the longest legal graffiti wall (almost 110m long) in the UK. Anyone can paint on the council-owned wall any time they like. Mike Crilley, the graffiti wall project organiser, promotes the positive side of graffiti and runs workshops for local children.
Is everyone doing graffiti? Can we do graffiti where we want these days? Not exactly. It’s illegal to paint on somebody else’s possessions, so make sure you find a legal graffiti wall like the one in Dundee if you want to have a go.

5 . No one can entirely predict where the artificial intelligence(AI)industry is taking everyone, but at least the AI is ready to reliably tell you what the weather will be like when you get there. According to a paper published in Science, a new, AI-powered 10-day climate forecasting program called GraphCast is already outperforming existing prediction tools nearly every time.
Developed by Lam, one GraphCast team member, and colleagues at Google DPMD, the technology company’s AI research division, GraphCast is trained on decades of historic weather information alongside roughly 40 years of satellite, weather station, and radar reanalysis. This stands in sharp contrast to what are known as numerical weather prediction(NWP)models, which traditionally use massive amounts of data concerning thermodynamics, fluid dynamics, and other atmospheric sciences. All those data require intense computing power. On top of all that, NWP models are slow—taking hours for hundreds of machines within a supercomputer to produce their 10-day forecasts.
GraphCast, meanwhile, offers highly accurate, medium range climatic predictions in less than a minute, all through just one of Google’s AI-powered machine learning tensor processing unit (TPU) machines. During a comprehensive performance evaluation against the industry-standard NWP system—the High-Resolution Forecast (HRES)—GraphCast proved more accurate in over 90 percent of tests. When limiting the scope to only the Earth’s troposphere, the lowest part of the atmosphere and home to most noticeable weather events, GraphCast beat HRES in an astounding 99.7 percent of test variables.
“Pioneering the use of AI in weather forecasting will benefit billions of people in their everyday lives,” Lam said. He noted GraphCast’s potential vital importance amid increasingly destroying events resulting from climate breakdown. “Predicting extreme temperatures is of growing importance in our warming world, ” Lam continued. “GraphCast can characterize when the heat is set to rise above the historical top temperatures for any given location on Earth. This is particularly useful in anticipating heat waves,disruptive and dangerous events that are becoming increasingly common. ”

The past summer in Antarctica, Elaine had spent long hours inside the plain, practical buildings of the MeMurdo research station. Her job was to look after the fire-fighting equipment and fire alarms of this remote outpost. But on her days off, Elaine loved to go skiing and explore the ice and caves beyond the station.
With winter coming, she’d be heading home soon. But before she left there was one more thing Elaine wanted to do. She was determined to see a penguin (企鹅) — up close. She’d heard interesting tales from the biologists, about how penguins played and took care of one another, how they were curious and often approached people. She had spotted a few, but only from far away. But that night after dinner, someone said there was a lone penguin on the ice on the far side of the station. Elaine rushed out, hoping to get a closer look.
Now she was filled with excitement.... and cold. The day had been sunny and warm (for Antarctica, meaning around 20°F or-6℃, still below freezing). But a sudden storm could drop the temperature by 50°in just a few minutes. The glacier’s (冰川) huge pressure created crevasses (冰裂缝) — deep blue holes in the ice beneath the snowy surface, If someone dropped into the crevasse, nobody would ever find him.
A frosty wind blew, and she reached up to cover her bare ear. Oh no, where was her hat? Elaine had left her backpack — with her warm coal, hat, and emergency radio — back at MeMurdo! Normally, she carried that orange pack everywhere. But hearing about the penguin, she’d rushed out without her backpack and she was out on the ice alone.
Maybe the cold had slowed down her brain, but Elaine didn’t consider the danger. All she could think of was the penguin. Watching the penguin coming closer, she spied a flash of yellow. It was an emperor penguin! Elaine followed the bird farther out on the ice, away from the base.
