1 . Having studied more than 400 groups of honeybees in Brazil for two years, a group of biologists led by Viviana Di Pietro report that, like humans, honeybees are capable of learning new traditions which are then handed down over generations.
“The most obvious example is that honeybees can build their homes according to different architectural traditions which are then handed down over generations,” they write. “We found that around 95% of the honeybees built their homes in a horizontal (与地面平行的) style, while 5% of them preferred a spiral (螺旋形的) structure. In each case, the tradition was passed down to the next generations.”
Since honeybees showed a strong preference for a horizontal structure, it was surprising that spiral structures occurred at all. “With the help of video cameras, we found that there was a noticeable difference in average building rate between the two styles.” the researchers add.
In order to rule out a genetic (遗传的) explanation for the different styles, the researchers took honeybees from the groups that built in spiral tradition close to the groups that built in horizontal tradition. The imported honeybees soon learned to build their homes in the local style, which was then passed down to their children as they eventually grew up. “It is very likely that the imported honeybees might have changed the style as a way of correcting the construction errors made by their ancestors.” the researchers suggest.
The findings have surprised observers of animal culture, as they suggest that honeybees can learn and hand down different building traditions over generations. This has changed the way of thinking about culture, which is often strictly defined as behaviour directly handed down from human parents to their children until it becomes a tradition in a group.
“Insect culture was thought impossible. Less than a century ago, culture was thought to be uniquely human,” says biologist Andrew Whiten of the University of St Andrews, who was not involved in the research. “But the new research has offered strong evidence pointing to the opposite.”

2 . Samarkand in Uzbekistan hosted an important intergovernmental conference on how to stop the slow spread of degraded (退化) land. Between 2015 and 2019, the world lost at least 100 million hectares of healthy and productive land a year, according to an analysis for the United Nations Convention to Combat Desertification (UNCCD). Human activities—including destroying forests and agricultural practices — and climate change are among the main causes.
115 countries reported ahead of the meeting on three measures for restoring degraded land and soil: protecting the area used for agriculture or covered by forests or wetlands; increasing the ability of land to support and sustain life, retaining above-and below-ground stocks of carbon. Reaching the target of “land degradation neutrality (土地退化中性)” by 2030 means reversing a negative trend: the global share of land that is degraded increased from 14.7% in 2015 to 18. 9% in 2019.
Yet there are some important signs of hope amid a mostly bleak prospect. The analysis enables countries to understand land degradation at a more granular (细致的) level than before. And the UNCCD’s science teams helped to train researchers in some of the most-affected countries, so that local scientists and policymakers could do the work themselves. And some countries are moving in the right direction. In Ecuador, for example, the area of land classed as degraded went from 21.9% to 12.8% between 2015 and 2019.
Land degradation is not a priority on the world’s environmental agenda. Although the UNCCD has the same status as the UN conventions on climate change and biodiversity, unlike them it does not have an autonomous body that provides independent scientific advice. Restoration projects also receive much less international funding.
This funding gap illustrates just how little priority is given to restoring land and preventing further countries are providing data. These nations, especially high-income countries, should start reporting degradation. Yet the latest analysis shows what can be done even with limited resources. But not all their plans and actions, to raise the profile of land degradation.

3 . “Earth” has always been an odd choice of name for the third planet from the Sun. After all, if an alien examines it through a telescope, he would note that two-thirds of its surface is covered not by earth at all, but by oceans of water.
However, most of the oceans on Earth remain unexplored. For example, photographers are fond of pointing out that scientists have mapped nearly all the oceans’ surface, but less than a quarter of the seabed. Biologists think the oceans might host more than 2 million species of animals, of which they have so far identified perhaps a tenth.
A new project may change this. Launched in London on April 27th, 2023, Ocean Census aims to discover 100,000 new species of ocean animals over the coming decade. Its first ship, Kronprins Haakon, set sail on April 29 for the Barents Sea.
The project is launched for two reasons. One is that the longer scientists wait, the less there will be to study. “Top on our agenda are species thought to be in the greatest danger from climate change,” says Oliver Steeds, founder of the project. “Otherwise, the forest is burning down and we won’t know what was there before it is lost.”
The second reason is technological. Biologists find about 2,000 new species a year, a rate hardly changed since Darwin’s day. Ocean Census is betting that it can go faster. Fancy cameras on remote-operated vehicles, for instance, allow scientists to scan deep-sea creatures such as jellyfish without removing them from their habitat. Just as the huge pressures of the deep sea are deadly for humans, taking such a jellyfish to the surface for examination may reduce it to gooey slime (黏液).
Exactly what the new effort might turn up, of course, is impossible to predict. But history suggests it will be fruitful. Half a century ago, scientists discovered hot seabeds that were home to organisms living happily in conditions that, until then, had been thought harmful to life. These days, such hot seabeds are thought to be one possible candidate for the origin of all life on Earth.

4 . Each spring, millions of people take photos among the famous cherry trees around the Tidal Basin in Washington DC-some even get married there. That’s what Jody Axinn did 10 years ago.
“Now, the romantic spot is unrecognizable. The whole section is under water,” says Axinn who is revisiting the cherry trees with her family. “When I got here 10 years ago, the place was flooded regularly, but certainly not twice a day, every day.”
There are two forces working together to affect the Tidal Basin, the trees and monuments around it. The seawall around the basin, built with mud dug up from the Potomac River bottom, has sunk about five feet over the past century.
“At the same time, the water level in the basin has gone up by more than a foot because of climate change,” explains Leslie Frattaroli, manager of the National Park Service (NPS). “The Tidal Basin looks like a small lake, but it’s actually part of the Potomac River, because there are gates at the upstream and downstream ends of the basin that allow river water to rush through. Therefore, it is gradually rising along with the level of the world’s oceans.”
Combining these two factors, the water is six feet above where the seawall was originally designed to keep it out. Later this spring, the park service will start to raise parts of the walkway around the basin and along the Potomac River.
“It would be impossible to complete the $113 million project without removing the cherry trees along the water,” Leslie says. “The good news is that when the project is completed in 2027, 274 new cherry trees will be planted.”
Among the trees to be removed is a very famous little tree known as “Stumpy”. At high tide (潮汐), the base of the tree is flooded. Although it is in extremely bad conditions, its remaining three or four small branches burst into flower each spring, with the Washington Monument standing tall in the background.

When I was a kid, my parents and I lived near the forest. They often told me that our family was a team that needed to work together for the household to function smoothly. There was always an abundance of work to do — cooking, cleaning, and walking dogs. I volunteered to walk our dog, Max, who had been adopted one month before. I never dared let this giant dog off the lead (牵狗绳), just in case he took off.
One morning, we were walking along in the forest when Max started pulling on the lead. At first, I was able to hold on despite the wet ground from a recent shower. But the more I tried to stop him pulling, the more it turned into a tug of war. And thanks to the slippery ground, I lost.
Pulling his lead, Max shot off like a bullet, leaving me screaming behind. I chased him but lost my footing and fell face-first into some mud. I stumbled (踉跄) to my feet, but looking ahead, I found him running back towards me. I thought he was going to stop and give me his “Sorry” look. But instead, the dog shot past me and returned after a while.
As soon as we got home, my mother immediately attended to Max with a warm towel and a doggy treat. I thought seeing me stumbling and covered in mud, I would also get a warm cup of tea and a motherly kiss. Instead, I got a very loud lecture about letting the dog loose in the forest.
I felt frustrated. It wasn’t fair that she didn’t understand how difficult it was to control Max. I fought back, “Stop lecturing me! Why is everything my fault?” With these words, I stormed into my bedroom and slammed the door shut.
In the evening, I heard my mother call Max and take him out. It wasn’t long before I heard my mother screaming and the door opening again.

It’s a fascinating story of how nature is reclaiming and transforming the broken soil we leave behind. Wildlife filmmaker Dan O’Neill and zoologist Yussef Rafik are on a mission to uncover the wildlife secrets hidden inside some abandoned places.
Inchkeith IslandThis island off the Scottish coast had been an important strategic location for military defences for over 500 years by 1957. While its buildings might be empty and in bad condition, the wildlife has bloomed. Dan and Yussef watch young seal pups on the beach and spot seabirds and European cave spiders.
Dinorwi c QuarryDan and Yussef visit this former slate quarry(采石场) in Wales. Dinorwic closed its doors in 1969 and nature has slowly been reclaiming the land ever since. Dan and Yussef are searching for the fastest animal in the world, the peregrine falcon(游隼) and spot rare wild mountain goats.
Chatterley WhitfieldToday it looks more like a set from a film, but at its peak Chatterley Whitfield was a busy coalmine. Since it was closed in 1977, wildlife has taken hold. Dan and Yussef find plants including sunflowers that have sprung up in the most unlikely places. And hidden cameras capture footage of the rabbits and foxes wandering these empty buildings at night.
Nunhead CemeteryDan and Yussef explore one of the seven great graveyards in London, which was closed right after the Second World War and soon became neglected. Now hundreds of species live alongside the dead. Dan spots bright green ring-necked parakeets, the non-native bird that’s made London its home and the pair sample blackberries growing among the graves.

8 . The green, natural forest absorbs carbon dioxide from the air through photo- synthesis (光合作用). There is another way of dealing with the climate crisis. That is setting up fields of dark-colored solar panels (太阳能电池板), also known as “solar forests”, which replace power stations that use fossil fuels such as coal and gas to make electricity, thus mitigating harmful emissions (排放) of greenhouse gases.
But since they are both relatively dark, they absorb a lot of solar radiation. Some of the energy is used for photosynthesis in natural forests or to produce electricity in “solar forests”, but most returns to the atmosphere, heating it up. Then what would be the more effective land use option in terms of the climate crisis: planting a forest, or building solar panels? This issue has long been debated by decision-makers around the world. Now, we may have an answer, thanks to a new study.
First, the researchers compared the impact of a forest on the climate crisis in a dry area to that of a solar farm in a similar environment. The researchers found that the albedo effect (反射效应) of both of these “forests” was similar, but that the absorption or prevention of carbon emissions was very different. It turns out that it takes 2.5 years for the heat emitted by solar farms to be balanced by the carbon emissions that are avoided, thanks to the energy they produce. In the case of a natural forest of similar size, it would take more than 100 years of photosynthesis to balance its heating effect.
The researchers also studied how the heating-cooling relationship changed in other climates and found that in more humid environments, the heating effect of planting large numbers of trees is smaller. And the break-even point is reached within 15 to 18 years.
“In dry places, building solar forests seems far more effective in addressing the climate crisis. Meanwhile, forests absorb about a third of annual carbon emissions and play a vital role in the global rain cycle, in maintaining biodiversity and in many other environmental and social contexts. Preventing them from being cut down and planting more trees in humid areas are of great significance,” explains one of the researchers in the study.
