3 . Fingerprints have been used to identify individuals for centuries. But now scientists may have finally figured out how those patterns are formed, according to a paper published in the journal Cell in February.
Previous studies have shown that fingerprints can be influenced by the shape and size of the blood vessels in the skin and how fast the different layers of skin grow. Denis Headon at the University of Edinburgh, UK, and his colleagues started their study from a new viewpoint: how genes affect fingerprint patterns. They identified the genes related to limb (肢体) development, which could serve as the groundwork for print formation, according to their work published in 2022.
However, many genes are not involved in the process. “The key is how they form,” Headon told Nature, a science journal. The team studied the ridges (脊) on mouse toes and human cells grown artificially.
They found two kinds of elements work against each other. A protein called WNT, which is important in skin development, promotes ridge formation. Another molecule (分子), called BMP, impedes the ridges. With the two elements “fighting” each other, they create the patterns of waves. The team also changed the timing and the location of the origins of the waves in experiments. They discovered that the waves would collide in different ways, which helps to create the diversity of print patterns.
Interestingly, the analysis of the fingerprint patterns supported the Turing reaction-diffusion system. It was first proposed by UK scientist Alan Turing in 1952 to describe a self-organizing system that creates patterns in nature, such as the feather patterns in birds and stripes on zebra. The researchers also built a computer model that can recreate print patterns by following the Turing system.
Based on the new study, it may be possible that the structures of human skin might be all generated by the same mechanism, Sarah Millar, a US biologist, told the website Science News. However, more studies on how the skin matures are needed to solve the mystery.

4 . My husband made a little two-story house that mirrored our own in color and design for our Little Free Library, while I carefully selected books from our shelves. The idea resonated (引起共鸣) with us immediately — instead of loading boxes into the car for yet another used book sale, we could simply walk them to the roadside.
Fifteen or so years later, it’s safe to say that thousands of books, as well as the occasional DVDs, CDs and jigsaw puzzles have been shared through our little library. Situated on a busy street just a few blocks from a subway station, our little library sees dozens, perhaps hundreds, of passers-by each day.
Many of those who use our library do not hesitate to share their love of this neighborhood resource. One gentleman regularly stops by to pick up books for a nearby retirement home. At other times, we have received cards and gifts, including chocolates and even a personalized drawing from a local artist.
Like the people who use our library, the books that come and go reflect the broad diversity of our city. Arabic, French and Russian books are staples among the dominant English-language books. I’ve even collected favorite books of mine in languages I don’t understand, simply for the joy of adding another edition to my collection. Surprisingly, our library hasn’t dealt with our book storage problem —if anything, we now have more books than ever before.
I have heard some complaints that Little Free Libraries do not always serve the purpose of building community and may compete with our public libraries and independent bookstores. This has not been our experience. We continue to buy more books than we need and we are fiercely loyal users of the public system. Our Little Free Library has enhanced our love of reading and has connected us to a community of book lovers in the heart of our busy neighborhood.

5 . The first wave of excitement about generative artificial intelligence (AI) has cooled a little. But an entirely new industry centred on generative AI models is taking shape. Three forces will determine what it eventually looks like.
The first factor is computing power, the cost of which is forcing model-builders to become more efficient. Faced with the eye-watering costs of training and running more powerful models, for instance, OpenAI is not yet training its next big model, GPT-5, but GPT-4.5 instead, a more powerful version than its current model, GPT-4. That could give deep-pocketed competitors such as Google a chance to catch up. Its soon-to-be-released cutting-edge model, Gemini, is thought to be more powerful than OpenAI’s current version.
High computing costs have also encouraged the development of much smaller models, which are trained on specific data to do specific things. Replit, a startup, has trained a model to help developers write programs, for instance.
All these models are now fighting for data—the second force shaping the generative AI industry. The biggest, such as OpenAI’s and Google’s, are always hungry: They are trained on more than one trillion words, which amount to more than 250 English-language Wikipedias. As they grow bigger, they will get hungrier.
Generative AI’s hunger for data and computing power makes a third factor more important still: money. Many model-makers are already turning away from generative AI models for the general public, and looking instead to fee-paying businesses. OpenAI, which started life in 2015 as a non-profit venture, has been especially energetic in this regard. It has not just licensed its models to Microsoft, but is setting up tools for companies including Morgan Stanley and Salesforce.
Who will emerge victorious? Firms like OpenAI, with its vast number of users, and Google, with its deep pockets, have a clear early competitive edge. But for as long as computing power and data remain limited, the model-builder with the smartest method to process data could yet steal the lead. So, the AI craze may have cooled, but the drama is just beginning.

6 . Having just finished a show in Times Square, Italian rocker Maneskin and his band learned that their Madison Square Garden show scheduled for the week was a sellout. Pleasantly surprised, Maneskin called the news very special, because it’s one of the most important places where every musician can ever dream to perform.
In an era when rock bands seem endangered and most of the top rockers came from the last century, Maneskin and his band seem to be an anomaly. Coming to public attention in 2021 after an unexpected win at the Eurovision Song Contest with their high-energy song, Zitti E Buoni, the Italian band seems to be reviving (复兴) rock music, or at least, providing a breath of hope.
“The band was born out of pure passion between four friends who met in high school,” Maneskin told reporters. “We never had the ambition to make a breakthrough in the music business as a rock band.”
Maneskin thinks that their success has something to do with the band’s experience on the streets of Rome as teenagers. “We had to get the attention of the people. So, we saw that interacting and getting close was something that really worked,” he admitted.
That is carried over to their live show, as they always break away from the main stage for a few songs to get closer to the audience. They also have brought fans onstage. The relationship between the artists and audience was intensified during their South America tours where the band was exposed to some of the most energetic audiences.
“People went crazy. They really screamed at the top of their lungs,” Maneskin laughed.
While they can easily be mistaken for rockers of a new era with their distinctive style and songs like I Wanna Be Your Slave or Supermodel, their music is strongly influenced by the rock of the 1970s and 1980s.
“We grew up listening to the rock music our parents played. When we started playing our instruments, our teachers introduced us to all the classic rock music bands of the past. It’s something that really shaped us into who we are today,” he said.

10 . Distance running, it turns out, is where humans are better at compared with other species, even if our two-leggedness makes us about half as fast as other mammals of similar size, on average.
So what is it about our bodies and our physiology that allows us to undertake such long and hard runs?
“Our ancestors developed adaptations for running literally from toe to head,” said Daniel Lieberman, a human evolutionary biologist at Harvard University who focuses on movement. “There’s no part of our body that running doesn’t touch.” According to Lieberman, our toes are short so they don’t break while running. And in general, our lower body has larger joints, tendons (筋腱) and muscles than our upper body that does to absorb the forces we generate at speed. Beefy muscles in our back keep our upper body from falling forward, and our swinging arms stabilize our heads. Unlike apes, we have a flexible spinal column (脊柱) that allows us to twist our hips and shoulders and separate them from our head so we can keep our gaze directed forward.
But perhaps the biggest adaptations that set humans apart deal with our ability to let heat out. Our tall, upright bodies create a lot of surface area for cooling, and the ability to breathe from both the nose and mouth helps dump heat as well. Humans are also one of the only species with the ability to sweat, and without thick fur, our sweat can easily evaporate from our skin, cooling us down.
All of these adaptations led humans to adopt what’s known as persistent hunting long before the appearance of early weapons. Hunters likely followed their quarry (猎物) for miles until the animals gave in to exhaustion. Other animals do this too, but none can persistently hunt during the day or in hot climates. Hunting gave humans access to more energy, which freed our brains to grow larger. In turn, our brains have developed our ability to run and hunt, said Missy Thompson, a neuromechanics biologist at Fort Lewis College in Colorado.
