1 . Researchers say they have translated the meaning of gestures that wild chimpanzees (黑猩猩) use to communicate. They say wild chimps communicate 19 specific messages to one another with a “vocabulary” of 66 gestures. The scientists discovered this by following and filming groups of chimps in Uganda, and examining more than 5,000 incidents of these meaningful exchanges.
Dr Catherine Hobaiter, who led the research, said that this was the only form of intentional communication to be recorded in the animal kingdom. Only humans and chimps, she said, had a system of communication where they deliberately sent a message to another group member.
“That’s what’s so amazing about chimp gestures,” she said. “They’re the only thing that looks like human language in that respect.”
Although previous research has shown that apes and monkeys can understand complex information from another animal’s call, the animals do not appear to use their voices intentionally to communicate messages. This was a significant difference between calls and gestures, Dr Hobaiter said.
Chimps will check to see if they have the attention of the animal with which they wish to communicate. In one case, a mother presents her foot to her crying baby, signaling: “Climb on me.” The youngster immediately jumps on to its mothers back and they travel off together. “The big message from this study is that there is another species (物种) out there. that is meaningful in its communication, so that’s not unique to humans,” said Dr Hobaiter.
Dr Susanne Shultz, an evolutionary biologist from the University of Manchester, said the study was praiseworthy in seeking to enrich our knowledge of the evolution of human language. But, she added, the results were “a little disappointing”.
“The vagueness of the gesture meanings suggests either that the chimps have little to communicate, or we are still missing a lot of the information contained in their gestures and actions,” she said. “Moreover, the meanings seem to not go beyond what other animal convey with non-verbal communication. So, it seems the gulf remains. ”

“I'm going to miss you so much, Poppy, "said the tall, thin teenager. He bent down to hug his old friend goodbye. He stood up, hugged his parents, and smiled, trying not to let his emotions(情绪)get the better of him.
His parents were not quite able to keep theirs under control. They had driven their son several hours out of town to the university where he would soon be living and studying. It was time to say goodbye for now at least. The family hugged and smiled through misty eyes and then laughed.
The boy lifted the last bag onto his shoulder, and flashed a bright smile.” I guess this is it, “he said.” I'll see you back home in a month, okay？"His parents nodded, and they watched as he walked out of sight into the crowds of hundreds of students and parents. The boy's mother turned to the dog, “Okay, Poppy, time to go back home.”
The house seemed quiet as a tomb without the boy living there. All that week, Poppy didn't seem interested in her dinner, her favorite toy, or even in her daily walk. Her owners were sad too, but they knew their son would be back to visit. Poppy didn't.
They offered the dog some of her favorite peanut butter treats. They even let her sit on the sofa, but the old girl just wasn't her usual cheerful self. Her owners started to get worried. "What should we do to cheer Poppy up？"asked Dad. “We've tried everything.”
“I have an idea, but it might be a little crazy, “smiled Mom.” Without anybody left in the house but us, this place could use a bit of fun. Let's get a little dog for Poppy."
It didn't take long before they walked through the front door carrying a big box. Poppy welcomed them home as usual, but when she saw the box, she stopped. She put her nose on it. Her tail began wagging(摆动)ever so slowly, then faster as she caught the smell.

3 . Any schoolchild knows that a whale breathes through its blowhole. Fewer know that a blowhole is a nostril (鼻孔) slightly changed by evolution into a form more useful for a mammal that spends its life at sea. And only a dedicated expert would know that while toothed whales, such as sperm whales, have one hole, baleen (鲸须) whales, such as humpback and Rice whales, have two.
Even among the baleen whales, the placing of those nostrils differs. In some species they are close together. In others, they are much further apart. In a paper published in Biology Letters Conor Ryan, a marine biologist at the Scottish Association for Marine Science, suggests why that might be. Having two nostrils, he argues, helps whales smell in stereo (立体空间).
Many types of baleen whales eat tiny animals known as zooplankton (浮游动物), which they catch by filtering (过滤) them from seawater using the sheets of fibrous baleen that have replaced teeth in their mouths. But to eat something you first have to find it. Toothed whales do not hunt by scent. In fact, the olfactory bulb—the part of the brain that processes smell—is absent in such creatures. But baleen whales still have olfactory bulbs, which suggests smell remains important. And scent can indeed give zooplankton away. Zooplankton like to eat other tiny creatures called phytoplankton (浮游植物). When these are under attack, they release a special gas called dimethyl sulphide, which in turn attracts baleen whales.
Most animals have stereoscopic senses. Having two eyes, for instance, allows an animal to compare the images from each in order to perceive depth. Having two ears lets them locate the direction from which a sound is coming. Dr Ryan theorized that paired blowholes might bring baleen whales the same sorts of benefits.
The farther apart the sensory organs are, the more information can be extracted by the animal that bears them. The researchers used drones to photograph the nostrils of 143 whales belonging to 14 different species. Sure enough, baleen whales that often eat zooplankton, such as the North Atlantic right whale, have nostrils that are farther apart than do those, such as humpback whales, that eat zooplankton occasionally. Besides allowing them to breathe, it seems that some whales use their blowholes to determine in which direction dinner lies.

4 . Jonathan the tortoise, the world’s oldest land animal, turned 190 over the weekend on the island of St. Helena, where he enjoyed a “cake” of seasonal fruits, leafy greens and vegetables, including carrots carved into the number “190”.
Jonathan was brought to St.Helena from the Seychelles in 1882 as a gift. According to Guinness World Records, Jonathan surpassed the previous record holder, Tu’i Malila, who lived in the 1770s until 1965and could be even older. He arrived in St.Helena as a fully mature tortoise, meaning he was at least 50 in 1882.
“The vet is still feeding him by hand once a week to boost his calories, vitamins, minerals and trace elements, as he is blind and has no sense of smell. His hearing though is excellent and he loves the company of humans, and responds well to his vet Joe Hollins’ voice as he associates him with a feast, Guinness World Records said.
“The tortoise enjoys the sun but on very hot days takes to the shade. On mild days, he will sunbathe his long neck and legs stretched fully out of his shell to absorb heat and transfer it to his core,” according to Hollins. When it’s cold, Jonathan has been known to “dig himself into leaf mold or grass cuttings and remain there all day.”
In most cases, the lifespan of a tortoise or turtle depends on the species and level of care they receive. They generally live much longer in captivity than in the wild, because in the wild, they must find their own food in addition to evading predators while not getting medical treatment. Larger turtle and tortoise species also tend to live longer than their smaller counterparts. For more information about animal record holders, click here.

6 . I was attacked by a tiger shark in late October 1997. It was near my home on the island of Kauai—a typical fall morning with friends. The waves were really good, so nothing was stopping us.
That is until a large shark came right up under me and sank his teeth into my lower leg. There had been no splashing. no noise, and I felt no pain, only great pressure on my lower body.
Then I followed my instinct: I punched the shark in the face, again and again which happens to be what the expert advice, until the shark released me. As I swam back into shore, I felt my lower right leg spasming(痉挛). When I looked down, I realized it was gone. The shark had bit my lower leg off. My friends rushed to my aid, and rushed me to hospital.
It was another day before the “fog” lifted, at which point I opened my eyes and realized I was in the hospital—a below-the-knee amputee(截肢). For the next few bedridden weeks, I spent time with my family, and considered the future.
As soon as I was given the OK by my doctors, I did what many of us might consider unthinkable: I started riding the waves again. In fact, my first time back was near the site of his attack. I was unshaken and curious—Was it because of the tides? The phase of the moon? I also recalled that the morning of the attack the water had a fishy smell. Was that what attracted the shark?
I was determined to research sharks, and I did learn something that would change my life: Humans are far more dangerous to sharks than the other way around, I tell Reader’s Digest. “I watched a documentary called Sharkwater, and I learned about the demand for shark fin soup and the fact that 70 million sharks a year are killed for their fins alone.”
My unique situation as a shark survivor empowered me to give sharks a voice. I began working with the Hawaii state legislature to help pass a ban on shark-derived products. I partnered with other like-minded shark attack survivors and marine biologists, and we headed to Washington to urge senators to create a nationwide bill protecting sharks.

7 . Animal rescuer and cinematographer Douglas Thorn’s passion for animals began when he was a little kid. “I started rescuing orphaned baby animals,” Thorn says. “And I wanted to be a wildlife cinematographer.”
When Thron grew up, he did just that, working for shows like Discovery Channels Shark Week, filming the great white sharks off the coast of Santa Cruz, California. But Thron says it was the Paradise Fire in California in 2018 that “pushed” him to do animal rescue activism work, putting his aerial cinematography skills to good use.
At the time, Thron was filming a man who was rescuing cats after the fire using an infrared hand-held camera. The camera uses heat to detect the animals at night Thron and the man talked about how incredible it would be to put one on a drone to detect animals more easily. “The animal's body temperature will glow on the screen and you can pick them out among the bricks and stones,” explains Thron.
The first animal Thron ever rescued was a dog in the Bahamas after a category-5 hurricane hit, which wiped out hundreds of houses. Thron tested out putting an infrared scope on a drone and found the dog.
“The drone really shaves off critical time so that the really badly hurt animals are able to be rescued,” Thron says. Once the scope picks up the “heat signature of an animal”, Thron turns a spotlight on the animal and zooms in on it, so he and the rescue crews can go and save the animal.
Thron has basically been “going non-stop since then”. His TV show, Doug to the Rescue, shows some of his heart-warming animal rescues, including after Hurricane Laura in Louisiana in 2020 and after fires in Northern California and Oregon. Thron also helped rescue koalas after fires damaged parts of Australia in 2020.

9 . Parrots consistently top the charts of the world’s smartest animals. A new discovery published by the Royal Society Open Science reveals to us what sets the intelligent individual monk parakeet (和尚鹦鹉) apart in a group.
Previously, it was thought that these birds introduced themselves to others with a sort of “catchphrase” that distinguished their identity. However, after running the vocalizations (发声) collected in this study through a machine learning program, a team led by Simeon Smeele, a doctoral student at Aarhus University in Denmark, found that the birds actually had “voiceprints” like humans that identify themselves in the group.
The researchers studied thousands of monk parakeet vocalizations from hundreds of birds in Barcelona across two years and ran these recordings through the program that identifies small differences in their calls.
“The voiceprint is the underlying quality of a voice that you can recognize in humans, and this is the first time that has been shown in another vocal learner,” Smeele said. For example, the voiceprint of your father is how you know it’s his voice, even if he isn’t present. “This is what I think could explain how they recognize each other, because it can be stable over very long periods of time.” he added.
“This shows that these birds also have that sort of information that they might be using in their complicated social interactions,” said Emily Du Val, Ph.D., a behavioral ecologist at Florida State University. “Research into animal communication has the potential to motivate the public into action to conserve animals. Recognizing who each other is and understanding how they interact with one another are important for human life,” she said.
This model can potentially be applied to other animals with vocal recognition like bottlenose dolphins, bat s and elephants. Future research will look into whether these voiceprints are recognized by all parakeets in the community or only a circle of close relatives.

10 . Recordings (录音) of angry bees are enough to send big, tough African elephants running away, a new study says. Beehives ( 蜂窝) either recorded or real may even prevent elephants from damaging farmer’s crops.
Years ago, scientist Lucy King and her team found that elephants avoid certain trees with bees living in them. Today, Lucy wants to see if African honeybees might stop elephants from eating crops.
But before she asked farmers to set up beehives on their farms, she needed to find out if the bees would frighten elephants away.
Lucy found a wild beehive inside a tree in northern Kenya and set up a recorder. Then she threw a stone into the beehive, which burst into life. Lucy and her assistant hid in their car until the angry bees had calmed down. Next, Lucy searched out elephant families in Samburu National Reserve in northern Kenya and put a speaker in a tree close to each family.
From a distance, Lucy turned on the pre-recorded sound of angry bees while at the same time recording the elephants with a video camera. Half the elephant groups left the area within ten seconds. Out of a total of 17 groups, only one group didn’t react to the sound of the angry bees. Lucy reported that all the young elephants immediately ran to their mothers to hide under them. When Lucy played the sound of a waterfall ( 瀑布) instead of the angry bees to many of the same elephant families, the animals were undisturbed. Even after four minutes, most of the groups stayed in one place.
Lucy is now studying whether the elephants will continue to avoid the sound of angry bees after hearing it several times. She hasn’t tested enough groups yet to know and she has now begun placing speakers in the fields to see if elephants are frightened away.
