1 . The high intelligence levels of orangutans (红毛猩猩) have long been recognised, partly due to their practical skills such as using tools to crack nuts and search for insects. But new research suggests the primate (灵长动物) has another handy skill: applying medicinal herbs intentionally to an open wound.
A male Sumatran orangutan known as Rakus was observed by the research team with a fresh facial wound in June 2022. Three days later, Rakus was witnessed feeding on the stem and leaves of a plant. Thirteen minutes after Rakus had started feeding on it, he began chewing the leaves without swallowing them, then used his fingers to apply the resulting juice directly on to his facial wound. He repeated this behavior for seven minutes and at last fully covered the wound with the chewed leaves. He then continued feeding on the plant for 30 minutes. Over the following days, there were no signs of infection. The wound closed within five days and was healed, with only a faint scar remaining after one month.
It is not the first time wild primate species have been spotted self-medicating: among other examples, Bornean orangutans have been seen rubbing their arms and legs with chewed leaves from a plant used by humans to treat sore muscles, while chimpanzees have been recorded chewing plants known to treat worm infections and applying insects to wounds. However, the new discovery is the first time a wild animal has been observed treating open wounds with a substance known to have medicinal properties. “In the chimpanzee case they used insects and unfortunately it was never found out whether these insects really promote wound healing. Whereas in our case, the orangutan used the plant, and this plant has known medical properties,” said Dr Caroline Schuppli, senior author of the research.
Rakus’s goal-oriented behavior and the medicinal properties of his chosen treatment offer insight into the origins of human wound care-the treatment of which was first mentioned in a medical manuscript dating to 2200BC. “It definitely shows that these basic cognitive capacities that you need to come up with a behaviour like this were present at the time of our last common ancestor most likely,” said Schuppli.
It remains unclear whether Rakus figured the process out for himself or learned it from another orangutan, although it has not been seen in any other individual.

2 . Some people today might be early risers because of DNA they take after Neanderthals tens of thousands of years ago, suggests new research.
When early humans migrated from Africa to Eurasia roughly 70,000 years ago, some of them mated with Neanderthals, who had already adapted to the colder, darker climates of the north. The ripple (涟漪) effects of that intermating still exist today: Modern humans of non-African ancestry (血统) have between 1 and 4 percent Neanderthal DNA. Some of that DNA relates to sleep more specifically, the internal body clock known as the circadian rhythm.
For the new study, researchers compared DNA from today’s humans and DNA from Neanderthal fossils (化石). In both groups, they found some of the same genetic variants involved with the circadian rhythm. And they found that modern humans who carry these variants also reported being early risers.
For Neanderthals, being “morning people” might not have been the real benefit of carrying these genes. Instead, scientists suggest, Neanderthals’ DNA gave them faster, more flexible internal body clocks, which allowed them to adjust more easily to annual changes in daylight. This connection makes sense in the context of human history. When early humans moved north out of Africa, they would have experienced variable daylight hours — shorter days in the winter and longer days in the summer-for the first time. The Neanderthals’ circadian rhythm genes likely helped early humans’ offspring (后代) adapt to this new environment.
Notably, the findings do not prove that Neanderthal genes are responsible for the sleep habits of all early risers. Lots of different factors beyond genetics can contribute, including social and environmental influences. The study also only included DNA from a database called the U.K. Biobank—so the findings may not necessarily apply to all modern humans. Next, the research team hopes to study other genetic databases to see if the same link holds true for people of other ancestries. If the findings do apply more broadly, they may one day be useful for improving sleep in the modern world, where circadian rhythms are disturbed by night shifts and glowing smartphones.

3 . For eight years, Sophie created realistic-looking limbs (肢) for those who wanted to fit in. But she longed to work on more odd designs that would stand out. Then she met Pollyanna Hope, a young amputee (被截肢者).
“She wanted something a little different on her leg: pictures of a cartoon she loved, Peppa Pig,” said Sophie, who is now based in London. So she designed a unique leg covered in tattoo-like images of Peppa and other pigs riding a bicycle and eating ice cream. Working with Hope made Sophie realize there was a potential market for limbs.
Since then, Sophie founded the Alternative Limb Project (ALP) to make artistic limbs. Her work includes an arm wrapped in sculpted snakes and a leg that looks like porcelain (瓷器) covered in a painted flowery vine. She makes about six limbs per year, always including clients’ ideas so that they receive a personal piece they can celebrate rather than hide.
Of course, a fancy-looking limb won't suit everyone. For Sophie, the basis is that each limb must satisfy a combination of comfort, beauty and functionality, and pushing too hard in one direction can weaken other areas. But for amputees who appreciate novelty, Sophie has some amazing ideas.
“I’d really like to make a candy-dispenser leg with colorful candies inside it” she says. “Or a cuckoo-clock leg with a wooden bird that pops out every hour.” Her goal is to fashion a striking limb.
“It’ll transform the limbs from an elephant in the room into a conversation piece.”

4 . Peru is prepared to approve new laws that would make it easier to investigate and punish researchers who engage in academic cheating, including paying to have their names added to a paper.
The move comes as Peru’s national science agency seeks to crack down on authorship buying and other dishonest practices. It recently removed two scientists accused of dishonest publications from a national registry that is key to receiving government sponsor, job promotions, and salary bonuses. And officials are investigating more than 170 other researchers at a Peruvian media report claimed were involved in academic misconduct, including 72 listed n the national registry who work at 14 universities in Peru.
The new laws will empower universities and government officials to punish such behavior. Dishonest publishing practices “transcend mere moral misbehavior” because they enable researchers to obtain government and private funding without telling the truth, says Edward Málaga Trillo, a member of Congress who is the driving force behind the bills, which lawmakers are expected to finalize early this year. “These individuals are operating academic cheating.”
Peru’s academic community has been struggling with a rising tide of false authorship and related problems. One cause, some researchers say, is a 2014 law that aimed to stimulate research by rewarding researchers who boost their publishing output. For example, under a scoring system used by universities, researchers can earn five points for authorship in a high-impact journal, and two points when the journal is lower impact. A massing points can bring bonus payments and career promotion.
Signs of dishonest publishing can be obvious, notes Nahuel Monteblanco, president of Cientificos. pe, a Peruvian group that investigates misconduct. Many of the papers cited by Punto Final have numerous co-authors from different nations with few prior publications on the same subject. “If your colleague consistently publishes 20 articles a year with co-authors from other countries, that’s highly suspect,” Monteblanco says.

Jack was new to Woodberry Forest School this year. He carried a secret burden: a stutter (口吃) that often brought about laughter from his classmates. This made him very upset. Shy and reserved. Jack chose to fade into the background rather than draw attention to himself. He felt like an outsider, never quite fitting in.
Jack was eager to exchange ideas with his classmates, but afraid of getting into trouble. Jack's science teacher, Katherine, a warm and caring woman often wearing a smile, noticed Jack's stutter and shyness. She observed how Jack struggled to express himself in class and how he would shy away when called upon to speak.
Determined to lend a hand, Katherine took Jack under her wing, encouraging him to embrace bravery and believe in his own abilities. Subsequently, Katherine adopted a set of systematic methods to help him. She was glad to find the potential in him, the intelligence and creativity that lay hidden beneath his stutter. Whenever possible, Katherine was always ready to praise his efforts, always declaring, "You are so great!” Whenever Jack stumbled over his words, Katherine always smiled at him encouragingly, providing him with the strength to continue. Day by day, Jack found himself speaking with greater confidence and fluency.
One day, Katherine announced that each student should give a presentation of a science project in front of the class. Jack's heart sank, the familiar fear and anxiety wrapping around him. How could he possibly stand before his classmates to give his ideas clearly, knowing that they would laugh at him? As the presentation drew near, Jack's anxiety mounted. Then came the big day. He watched his classmates take turns to walk up to the front. They gave their presentation with confidence and backed to their seats with satisfaction. However, while Jack was waiting for his turn, his heart beat so violently that he felt as if he were sitting on pins and needles.
