1 . My grandma passed away last week. My mum began the painful yet necessary task of sorting through her belongings.
“Is there anything you want from grandma’s flat?” Mum texted me.
“Her aloe (芦荟), please.” I required zero thinking time.
Sometime around 1975, Grandma, always believing good things would happen in the future, received this plant as a gift, which she appreciated and placed in her doorway. It came from the local butcher. Five years later, my mum married the butcher’s son and had me. Grandma revealed to me this particular plant was a living relationship between the two families. And so was I.
Recently, whenever we visited Grandma’s flat, I attempted to fix this concept in my children’s minds. “That was a gift your great-grandma bought your other great-grandma! It’s older than me!” Then my kids would nod and ask Grandma for a sweet.
Numerous times, Grandma gave me cuttings or clippings of the plant, hoping I might raise my own and continue the legend. Yet, every time, my new branch died with my awful gardening skills. But that didn’t used to matter, because I could turn to Grandma, who would wait and accept my disturbance without becoming upset. Then I got another clipping and tried again. But now I can’t. So, I decided that the plant will go and live with Ann, my mother-in-law, who is a genius with a greenhouse.
The plan is for Ann to keep hold of the original plant. In time, she can teach me how to deal with its cuttings properly, and then maybe one day I can settle the plant in my place.
In the meantime, Ann will allocate (分配) clippings among my relatives, as Grandma used to do. My wife’s two sisters, for example, are both better at tending plants than I am, so it is quite imaginable they, too, will offer cuttings of the plant to their partners, spreading this loving plant across my entire extended family.

2 . In the forest of New Mexico, scientists are carrying two ten-day-old Mexican wolf pups (幼崽) riding in a backpack, searching for a Mexican wolf pair that has just given birth to six pups.
Mexican wolves were extinct in the USA by the 1970s, but there was a plan to bring them back. The first step was to trap five wild Mexican wolves and breed them with two caged ones. In 1998, the first caged-born adult Mexican wolves were released into forests.

| F．After that, the wolf parents won’t mind taking care of the new pups. |
| G．The wolf mum and dad don’t know it, but they’re about to adopt two more! |
3 . Sometimes called “Earth’s twin,” Venus is similar to our world in size and composition. The two rocky planets are also roughly the same distance from the sun, and both have an atmosphere. While Venus’s cold and unpleasant landscape does make it seem far less like Earth, scientists recently detected another striking similarity between the two, the presence of active volcanoes.
When NASA’s Magellan mission mapped much of the planet with radar in the 1990sit revealed an unexpectedly youthful surface-there were surprisingly a few craters (火山口)which suggested active geologic (地质的) processes. Although few missions have visited Venus since then, researchers have continued to mine the collection of data from.
Using this decades-old data, planetary scientist Robert Herrick discovered that a Magellan. volcano called Maat Mons is alive with volcanic activity. In this case, lava(岩浆)flows that moved for eight months during an imaging cycle from 1990 to 1992, according to a study published in Science in 2023. The findings are the first real evidence that volcanoes have erupted on Venus during modern times.
What’s more, volcanic activity on Venus could be even more common and dramatic than on Earth. A study published in JGR Planets in 2023 mapped out enormous potential volcanic features on Venus’ surface, and there’s a good chance that some of them could be active today. On top of that, another 2023 study, also in JGR Planets, found that the very high surface temperature on Venus, over 900 degrees Fahrenheit, allows lava flows to slowly leak out.
A list of new missions are headed to Venus over the next decade, including NASA’s Veritas mission, which aims to map the planet’s surface to better understand its geologic history. These projects should settle the question of how the paths of Venus and Earth divided so sharply, with one becoming a hell and the other able to harbor life, and confirm whether volcanoes are still erupting on the planet today.

4 . Spending your nights sleeping for just four seconds at a time might sound painful, but not for chinstrap penguins (帽带企鹅), which fall asleep thousands of times a day, new research finds.
Scientists studying the chinstrap penguins on King George Island in Antarctica found they nod off more than10,000 times a day, allowing them to keep an eye on their nests all the time, protecting eggs and chicks from predators (捕食性动物).
“Nesting penguins took over 600 ‘microsleeps’ an hour, each lasting only four seconds,” researchers wrote in the paper, published in the journal Science. The findings suggest “microsleeps can perform at least some of the functions of sleep”.
Sleep seems to be common among animals, but it makes them vulnerable because they lose the ability to respond quickly to the outside environment.
The researchers studied chinstrap penguins in the wild using electronicephalogram (EEG) monitoring. Microsleeps were shown by sleep-related brain activity and eye-closure. They noticed a slight increase in the depth of sleep at around noon, when risk of predation could be at its lowest.
Studies have shown some species routinely sleep very little, seemingly without negative costs to their performance while awake. African bush elephants sleep on average for two hours a day, and mostly while standing up, one study found. Sometimes they went 48 hours without sleeping.
Giant frigate birds can spend months on the wing during ocean migrations (迁徙). During this period they can sleep for less than an hour a day, while still flying and hunting. When they get back to the nest they sleep for nearly 13 hours a day.
“Sleep seems to be flexible among species,” a researcher said. “I believe that there are still many things unknown about animal sleep.”

5 . Eating insects is one of those ideas that never quite seem to catch on. The United Nations spread the idea a decade ago, but, in the West at least, insects remain mostly absent from supermarket shelves. Faced with an unsatisfied public, scientists have been exploring other options. One is to feed the insects instead to farm animals, which are not so picky.
Of course, the insects need to eat, too. To date, they have mostly reared (饲养) on leftover chicken feed. But the supply of that is limited, and if insect-reared meat is to take off, new sources will be needed. Niels Eriksen, a biochemist at Aalborg University, suggests feeding them on the waste products of the beer industry.
The world knocks back around 185bn litres of beer every year. Each litre produces between three and ten litres of wastewater full of thrown-away grains. The mix is rich in protein but lacking in carbohydrates (碳水化合物), especially compared with chicken feed.
Most insects grown for feed depend, in the wild, on the carbohydrates found in bad fruit. Whether insects would actually consider beer waste a square meal was, therefore, unclear.
The researchers used the baby insects of the black soldier fly. The young insects were divided into three groups, which were offered beer waste, chicken feed or a mixture of both. The researchers monitored both their weight gain and the amount of CO, they produced. They found the baby insects happily consumed both beer waste and chicken feed, and grew equally well on either food source. Dr Eriksen found few differences in how nutritious the insects would be to farm animals.
The experiment may have implications beyond the beer business, too. Bone meal from farms, and waste from other food industries are all likewise plentiful and protein-rich.
All now look to be reasonable targets for nutrient recycling by insects. Whether consumers will be willing to eat insect-reared beef, though, remains to be seen.

6 . Climate change is not only a human problem; animals have to adapt to it as well. Some “warm-blooded” animals are shapeshifting (变形) and getting larger legs, ears, and beak s to better control their body temperatures as the planet gets hotter. Bird researcher Sara Ryding of Deakin University in Australia describes these changes in a review.
“It’s high time we recognized that animals also have to adapt to these changes, and this is occurring over a far shorter time than would have occurred through most of evolutionary time,” says Ryding. “The climate change that we have created is putting a lot of pressure on them, and while some species will adapt, others will not.”
Ryding notes that climate change is a complex phenomenon that’s been occurring gradually, so it’s difficult to determine just one cause of the shapeshifting. But these changes have been occurring across wide geographical regions and among a variety of species, so there is little in common apart from climate change.
Strong shapeshifting has particularly been reported in birds. Several species of Australian parrot have shown, on average, a 4% to 10% increase in size since 1871, and this is positively associated with the summer temperature each year. North American dark-eyed juncos, a type of small songbird, had a link between increased size and short-term temperature extremes in cold environments. There have also been reported changes in mammalian (哺乳动物) species. Researchers have reported tail length increases in wood mice. “The increases in appendage (附肢) size we see so far are quite small — less than 10% — so the changes are unlikely to be immediately noticeable,” says Ryding. “However, prominent (突起的) appendages such as ears are predicted to increase.”
Next, Ryding intends to investigate shapeshifting in Australian birds by 3D scanning museum bird samples from the past 100 years. Undoubtedly, it will give her team a better understanding of which birds are changing appendage size due to climate change and why.

7 . Hummingbirds (蜂鸟) are a very important part of Mexico’s ecosystem, but because of the ever-spreading city landscape, they face all sorts of serious dangers. That’s where 73-year-old Catia Lattouf de Arida comes in. As a self-taught hummingbird care-taker, she devotes most of her free time and resources to nursing the tiny birds back to health. Her home in Mexico City has become known as a hummingbird hospital
Catia’s story as a hummingbird nurse began in 2011, at a very dificult moment in her life. At that time, she focused on her battle with cancer and fell into a depression (抑郁) . She was walking on the strect one day when she noticed a hummingbird that had suffered a serious eye injury. The kindhearted woman took it home and named it Gucci. She managed to nurse Gucci back to health, but she said it was Gucci that saved her. Why? Because the hummingbird managed to pull her out of the sadness and loneliness that had taken over her life.
Word of her success spread among Catia’s friends, and before long some of them began bringing her injured hummingbirds. She didn’t repulse them at all. She began to study the bird and their habits in order to better take care of them, and after 11 years of experience, the 73-year-old woman is considered an expert on hummingbirds.
In order to raise awareness of the difficult situation of hummingbirds in Mexico, Catia Lattouf de Arida started posting videos of the patients in her Mexico City apartment on social media, and many of them became popular. That’s when the need for her nursing services really blew up. She has cared for hundreds of hummingbirds in her 11-year career, when she has had as many as 50 of them in her apartment at any one time. She spends pretty much all her time looking after the tiny birds.

10 . Like dogs, wolves can recognize and respond to the voices of familiar humans more than those of strangers, according to a recent study. The research challenges the belief that dogs ability to differentiate human voices is due to selective breeding (选择性繁殖).
Holly Root Gutteridge and colleagues carried out experiments across five zoos and wildlife parks in Spain, involving a total of 24 gray wolves. The team set up speakers and first played the animals the voice of a number of strangers. Then, they played the wolves the voice of their keeper who would say familiar things to them in Spanish, such as “Hey, what’s up, wolves?” The wolves raised their heads, pricked their ears up, and turned toward the speaker. To test that the effect wasn’t accidental, the researchers went back to playing the wolves recordings of strangers and found that they once more lost interest. Finally, to make sure that the wolves truly knew their keepers’ voices, the team mixed things up and had the keepers say a series of unfamiliar phrases. Once more, the results held up.
Root Gutteridge pointed out the significance of wolves being able to differentiate between humans, despite the fact that our species went our separate evolutionary (进化的) ways tens of millions of years ago.
Before this, there had been a limited number of studies on the topic of how animals differentiate between the vocalizations (发声) of other species. Research has shown that our close cousins, gorillas, listen to people, but that was expected.
Given the new finding, “chances are that lots of species are listening to us and getting to know us as individuals,” Root Gutteridge said. “And it’s not all about us. Dogs could be listening to the neighbors’ cats and understanding the difference between one meow or the other. If the abilities are that general, it means that animals might be having a lot more cross- species interactions than we had thought about before.”
