1 . Most people would be terrified of entering waters with crocodiles (鳄鱼), but not Sao Chan. Like others living in a jungle village, the 73-year-old farmer says the Siamese crocodiles found in the waterways may look ferocious, but they should not be treated with prejudice. “If we come close to them, they just run away,” Chan says.
He’s right. There have been extremely few reported attacks by Siamese crocodiles on humans in the world, and reportedly none anywhere in Cambodia. Instead, it’s the crocodiles that have every reason to fear people. Once common throughout Southeast Asia, the particularly shy Siamese crocodile, which can grow up to 10 feet long, was for decades hunted for its skin and meat to such an extent that, in the early 1990s, the species was thought to be extinct in the wild.
Some of them survived in the Cardamoms, however, where populations of the reptiles, likely numbering fewer than 200 individuals in total, were rediscovered in 2000. Since then, local people have conducted regular patrols (巡逻) to protect them from threats. While the patrols and other conservation efforts have helped prevent the extinction of the Siamese crocodiles, concerns about the species’ long-term survival have remained because population numbers have stayed largely flat since their rediscovery.
In 2022, conservationists have introduced more Siamese crocodiles into the wild than ever before, not just in the Cardamoms but for the first time into a wildlife reserve in the northern part of the country, where the crocodiles historically were found. Advances in genetic testing have identified crocodiles suitable for release, and satellite tracking of reintroduced crocodiles has improved protection efforts.
“We have a long way to go, but the potential comeback of the Siamese crocodile could be Cambodia’s most successful conservation story,” says Pablo Sinovas, who leads a nonprofit reintroducing the animals. “Its survival isn’t just an ecological necessity, but a symbolic matter of urgency if we have any hope of preserving nature on Earth.”

2 . Fountains of lava erupted from the Sundhnúkur volcanic system in southwest Iceland on January 14th, 2024. Lava flows welled up from a new gap, attacking the suburbs of Grindavík with at least three houses in their path burnt down. Nearby, construction vehicles that had been working for weeks to build large earthen dams in an attempt to divert(使转向)the lava’s flow had to pull back.
Lava is subject to gravity like other fluids, so it will flow down along a path of steepest descent(斜坡). With the temperature of its molten rock often well above 1,000 degrees Celsius, not much can stand in its way. Humans have tried many ways to stop lava in the past, from attempting to freeze it in place by cooling it with sea water, to using explosive s to cut off its supply. However, no attempt was successful.
Most recent efforts have focused instead on building dams in an attempt to divert the lava’s flow toward a different path of steepest descent, into a different “lavashed,” where lava would naturally flow. Results have been mixed, but diversion can be successful if the lava flow can be clearly diverted into a distinct area where lava would naturally flow — without threatening a different community in the process. Many attempts to divert lava have failed, however. Barriers built in Italy to stop Mt. Etna’s lava flows in 1992 slowed the flow, but the lava eventually over topped each one.
Diverting lava in Grindavík is difficult, in part because the land around Grindavík is relatively flat, making it harder to identify a clear alternative path of steepest descent for redirecting the lava. Icelandic officials reported on January 15th that most of the lava from the main fissure had flowed along the outside the barrier, however a new gap had also opened inside the perimeter(外围), sending lava into a neighborhood. Unfortunately, that implies that Grindavík remains at risk.

3 . Humans have sailed the oceans’ surfaces for millennia, but their depths remain effectively uncharted. Only about a quarter of the seafloor has been mapped at high resolution. Maps of most regions display only approximate depths and often miss entire underwater mountains or canyons (峡谷).
So researchers have introduced some deep-diving experts: Elephant Seals. Scientists have been placing trackers on them around Antarctica for years, gathering data on ocean temperature. For a new study, the researchers compared these dives’ location and depth data with some of the less detailed seafloor maps. They spotted places where the seals dove deeper than should have been possible according to the maps meaning the existing depth estimates were inaccurate.
In eastern Antarctica’s Vincennes Bay, the diving seals helped the scientists find a large, hidden underwater canyon of more than a mile in depth. An Australian research ship called the RSV Nuyina later measured the canyon’s exact depth using sonar (纳),and the researchers have proposed naming their find the Mirounga-Nuyina Canyon — honoring both the ship and the involved Elephant Seals, genus Mirounga.
But seals can’t chart the entire ocean floor. The trackers used in the study could pinpoint a seal’s geographical location only within about 1.5 miles, which allows for useful but not exactly high-resolution data. Plus, because the seals don’t always dive to the bottom of the ocean, they can reveal only where the bottom is deeper than in existing maps- not shallower. Deep-sea research experts suggest improving on these data by using more precise GPS trackers and analyzing the seals’ diving patterns to determine whether they have reached the seafloor or simply stopped going down.
The potential use of the current seal-dive data is to gather information about the deep ocean around Antarctica, specifically regarding the location and depth of sea-floor canyons. This data can be valuable for predicting how Antarctica’s ice will melt. By understanding the presence and characteristics of these canyons, scientists can better assess how warmer water from the deep ocean flows towards the ice along the continent’s coast, This knowledge is crucial for accurately modeling and predicting the future behavior of Antarctica’s ice sheets and their contribution to sea-level rise.

5 . When this year’s all-woman team arrived on Antarctica’s Goudier Island to run the world’s most remote post office, it was shovels they needed rather than stamps.
They’d traveled some 8,000 miles from the UK, by plane and boat, and Britain’s Royal Navy had helped them dig out their new home at the Port Lockroy scientific base, which was buried up to four meters deep under several tonnes of December snow.
It wasn’t just the frozen wastes that first struck postmaster Clare Ballantyne, who at 23 years old was the baby of the four-woman group. It was that “there’s penguins everywhere.”
More than a thousand Gentoo penguins live on this tiny island on the western side of the Antarctic peninsula (半岛), around the size of a soccer field. Since 1944, when the UK’s first permanent Antarctic base was established here, it’s also become a shelter for explorers, scientists and — in recent years — tourists.
Each year, a team is selected to run and maintain the site from November to March, or summertime in the southern hemisphere. Around 4,000 people applied for this job, but just four made the cut: Ballantyne, base leader Lucy Bruzzone, wildlife monitor Mairi Hilton and shop manager Natalie Corbett.
The job also involves counting penguins: The scientific data they gather on the Gentoos’ breeding patterns is part of a decades-long study of the colony.
When it comes to choosing candidates, “there is no recipe we can follow,” says Ballantyne. “It’s about your ability to work together as a team. Cheeriness goes a long way, being able to see the light in life and resolve problems quickly.”
Ballantyne notes that there has been “a bit of a decline in recent years in the breeding success” of the Gentoo penguins, but says “the causal connect ion is the tricky bit.” While climate change is probably “the biggest driver,” they also need to carefully examine if there’s a “human element” as well. In her opinion, Antarctica tourism has boomed significantly in the past couple of decades, but there aren’t legally enforced limits on tourism, which hopes to be a regulated industry.

9 . Foxes in southern England have apparently developed a taste for automobiles. Instead of wanting to drive them, though, they’re eating vital components. The damage hasn’t just cost U.K. drivers thousands in repair bills. The foxes have also caused dangerous accidents when people have taken to the roads without realizing their brakes no longer work.
Already in 2009, police in the southern county of Kent warned drivers to check their cars’ wires and test their brakes before driving. Indeed, for some reason, the foxes seem to find brake lines particularly attractive. With their cars’ cables broken, drivers have had to get their vehicles fixed. That has resulted in occasionally sky-high bills. The damage has also resulted in accidents. Fortunately, we didn’t find any casualties linked to the foxes, but faulty brakes and cables connected to the animals have been behind crashes and stranded (抛锚) vehicles.
To stop the greedy beasts, motorists have tried all manners of techniques. Yet, the most effective way to keep the foxes away they’ve discovered is wrapping their cars in chicken wire. It’s a trouble to constantly have to take the wire off and put it back on, not to mention the potential scrapes and scratches on the paint. But suppose it’s better than having to get your brake lines repaired — again.
But why are the foxes so crazy about biting car cables? Nobody can say for sure, but it’s most likely a sum of multiple causes. First of all, the insulation materials (绝缘材料) on car cables in the U.K. were changed from petroleum-based materials to soy-derived substances some 15 years ago. Rodents (啮齿动物), from rats to squirrels, have been attracted to the vegetable-based coatings and it could be that foxes find them delicious as well. Another reason probably lies in England’s disappearing woodlands. With fewer wild places left, the foxes are increasingly driven towards cities to find food. And then there’s the issue of people feeding them.
“Foolish people have been feeding foxes and treating them as pets,” said animal psychologist Dr. Roger Mugford. “They normally avoid humans and anything’s been touched by humans but if they are getting food given to them, that’s changed.” If some drivers have been feeding foxes. they’ve brought this problem on themselves. Unfortunately, those same foxes will then proceed to haunt the entire neighborhood
