1 . In the past months, humans have become quite familiar with the term “social distancing”. But it turns out that we are not the only ones to avoid contacting our peers when our health may be at risk. Research suggests honeybees do it, too. “It’s exciting to see that other animals are doing something analogous,” said Dr. Alessandro Cini, co-author of the research at University College London.
Scientists have found that when a hive of honeybees is under threat from the mite called Varroa destructor, which can cause the collapse of honeybee colonies, the bees will respond by changing the way they interact with one another.
By examining videos recorded inside the hives, the researchers found that when hives had mites, foraging bees performed important dances to indicate the direction of food sources and kept themselves away from the centre of the colony where young bees and the queen stayed. This may help to keep the infection at a level that can be controlled, limiting the amount of damage. “Foragers are one of the main entrance routes for the mites,” said Cini.
The team then carried out experiments in the laboratory, artificially infecting small groups of about 12 young bees with the mites and comparing them to uninfected groups. This time, the team found no increase in social distancing among infected groups which, says Cini, may reflect that it is more important for foragers and young bees to keep their distance when the mites are present, and that bees rely on one another.
“Probably social distancing is too costly on a small scale,” he said. But there were differences in grooming behaviour: Infected bees were groomed more, inspected more, and had food shared with them more than individuals in uninfected groups.
Cini said the study showed the power of natural selection in the evolution of social behavior and also dynamic change in the social behaviour to adapt to an ever-changing environment.

2 . When wildfire smoke from huge fires in Canada blanketed the US in the summer of 2023, emergency rooms saw an increase in admissions for lung problems, heart attacks and other health issues.
Burning fossil fuels has driven climate change, and now climate change is costing people their health and increasingly their lives, says a new report from the medical journal The Lancet. The eighth annual Lancet Countdown, an international analysis that tracks nearly 50 different health-focused issues affected by climate change, calls for an immediate wind-down of fossil fuel use.
Those with the least historical responsibility for causing climate change are feeling the worst effects. Pakistan—a country responsible for roughly 0.3% of all climate-change-causing carbon emissions, suffered huge floods in 2022 that displaced more than 30 million people and killed at least 1,700. However, wealthier countries cannot be spared. In the US, wildfire smoke this summer sent people to the emergency room from New York to Georgia. In Europe, a 2022 summer heat wave resulted in over 60,000 deaths.
About one fifth of all US residents work outdoors; the percentages are even higher in many other countries. When it gets too hot, it gets harder and harder to work. Last year, the report says, outdoor workers lost more than 140 hours each — or several weeks of pay — because of the intense heat.
The human and economic costs are forecast to grow with every tenth of a degree hotter the planet gets. Heat-related deaths, for example, could increase by nearly five times by the middle of the century, if without immediate reductions to carbon emissions.
“I have a young patient who presents with uncontrollable asthma. She lives right next to a highway and is breathing in harmful air from cars burning gas,” Renee Salas, a doctor at Harvard’s Chan School of Public Health says. “So the treatment she needs is electric vehicles, home weatherization and air purification. These are prescriptions I can’t write.”

4 . New research from the University of Portsmouth has shown a marked increase in shipping in the North East Atlantic. Scientists now warn that more monitoring is required to help protect sea life.
Researchers at the University of Ponsmouth have discovered that rates (率) of shipping in the North East Atlantic area rose by 34 per cent in a five-year period. The research is the first detailed survey of shipping activity in the North East Atlantic. Researchers used data from over 530 million vessel (船) positions recorded by Automatic Identification System(AIS). They looked at the change in shipping between 2013 and 2017 across ten different vessel types. In total the study area covered 1.1 million km², including waters off Belgium, Denmark, France, Germany,Iceland, Ireland, The Netherlands, Norway, Portugal. Spain, and the UK.
Lead author, James Robbins said: “This change is likely to put more pressure on the marine (海洋的) environment, and may influence the protection of at-risk species. Renewed monitoring effort is needed to make sure that protective measures are enough to save species under threat in a changing environment.”
Some of the greatest shipping increases were found in areas close to the Spanish coast. The Espacio Marino de la Costa da Morte saw a rise of 413 percent in vessel activity. It is an area used to protect seabirds.
Dr. Sarah Marley, Visiting Researcher at the University of Portsmouth, said: “Shipping is the most widespread human activity in our oceans, carrying a set of threats-from unnoticeable effects like underwater noise pollution to serious results when ships hit whales.”
Professor Alex Ford. from the University’s Institute of Marine Sciences, said: “Given the well-documented effects that shipping can have on the marine environment, it is necessary that this situation continues to be monitored-particularly in areas used to protect vulnerable (脆弱的) species which may already be under pressure.”

5 . Every year, as the surface water temperature off the United States mid-Atlantic coast rises steadily from late spring through the summer, a pocket of uncharacteristically cool and crisp water gets trapped at the bottom of the ocean. Packed with nutrients this thick band of cold water, known as the mid-Atlantic cold pool, is a vital home for shellfish species. Extending at its seasonal peak from Nantucket, Massachusetts, to Cape Hatteras, North Carolina, the cold poll creates a diverse ecosystem ranging from algae(海藻)to fish — and some of the most valuable shellfish fisheries in the United States.
Now, however, two pressures have scientists worrying about whether the cold pool will last. The first is no surprise: climate change. Over the past five decades, climates change has destabilized the cold pool, causing it to warm and shrink. Compared with 1968, the cold pool is now 13℃ warmer and has lost more than one-third of its area.
The second concern is 1ess certain. In 2023, the US federal government approved plans to install(安装)98 wind turbines(涡轮机)off the New Jersey coast, covering an area of more than 300 square kilometers. Yet putting so many turbines to the seafloor could have unexpected consequences for the cold pool. That’s why Travis Miles, a researcher at New Jersey’s Rutgers University, and his colleagues are investigating. So far, Miles and his colleagues can’t definitively say what will happen to the cold pool, saying more research is needed to assess how climate change and offshore wind, together, could affect the cold pool. However, their initial analyses suggest the cold pool should be fine — at least in normal conditions.
New Jersey’s offshore wind plans are strongly opposed mainly by fossil fuel-industry funded efforts. Miles worries that an overabundance of caution or fear of potential impacts, including on the cold pool, might slow down the development of renewable energy. “...it’s quite clear that climate change is far more damaging than installing wind farms,” he says. “I don’t think any scientist would argue with that.”

“Bang. . !” Sara pushed the door open. She threw her school bag onto the floor and called out, “I’m home!” No answer. The house was silent. It sounded empty, but she knew it wasn’t. Her mum and dad were working upstairs.
Sara got a glass of orange juice, went into the conservatory (玻璃房) and sat down in her favourite chair. The garden was still in the dark afternoon. On one side, her mum’s garden was neat and tidy with boring short grass, boring straight flowerbeds and boring straight paths. But on the other side, Sara’s Nature Garden looked wild and exciting with big dead sunflowers and tall grasses.
“Nobody is interested in me. Mum and dad only think about their work,” she thought sadly.
Then she recalled: One month earlier, she learned in a magazine that many dogs were abandoned because their owners got bored with them; One hour earlier, she saw a cute dog wagging its tail and licking her friend’s face.
Sara knew today was special. Today things were changing. She couldn’t wait any longer. It’s time to talk to her parents.
So Sara got up from her chair and climbed all the way to the loft (阁楼). “Mum, I want a talk.” said Sara. “Just a minute!” Her mum clicked on the keyboard, took off her glasses and turned to her daughter. Sara coughed, took a deep breath, and told her mum that she wanted a dog. “No, Sara. That’s impossible,” her mum said firmly. Sara went to her father but got the same answer. She rushed into her room angrily and slammed the door shut.
Later, Sara’s mum knocked at the door and went in. “Darling, we know this is important to you. You can have a dog if you take the responsibility. But look at your Nature Garden, your school bag, your bedroom! What a mess! Do you think you can take good care of a dog?” said her mum.

9 . My first dependant was a duck called Mr. Kite. As a cream-faced four-year-old, it was my job at the nursery to turn the eggs in the incubator (恒温箱) every day: one side “O”, the other side “X”.
We lived in a small, inner-city house with a long, thin garden in east Oxford at the time. As a gentle-hearted vet's (兽医的) daughter, my mum couldn't resist adopting these ducks. I named them Buttercup, Mr. Kite and Drakey. We made them a pond. The bottom was a mosaic (马赛克) made from all the bits of plate and cup that had been broken during family rows. Within 30 seconds,the pond was so full of duck droppings that we never saw the mosaic again.
One of the most magical moments during my caring for ducks was the night it snowed. Mum, over whelmed by pity and grandmotherly concern, insisted that Mr. Kite and her friends — yes, Mr. Kite was female — be spared another freezing night in the wooden house my dad had built for them at the end of the garden; we caught them, flapping and shouting, and brought them in to sleep in the kitchen.Have you ever seen three ducks go wild in a tiny kitchen? It was one of the best moments of my childhood. It smelled like the underside of hell's socks by the time they had left.
I used to spend my summers lazing in a swimming pool with Mr. Kite and the others. Eventually, though, our neighbour complained that they were being woken at 4:45 a.m.. So, the feathered three went to live with an old couple in the country. Fair enough — you don't move to the city to have the dawn torn apart by quacking — although it must have made a change from student parties and the sound of 19-year-olds being sick by the bins.
I wonder now if this early experience of duck adoption is the reason that, at least three times a week, what ever the weather, you will find me swimming in the Thames or a nearby lake with the ducks. Although they never say hello.

10 . Since the 1950s, some 9.2 billion tonnes of plastic have been produced globally, of which only about 10% has ever been recycled. Yet environmentally conscious companies and consumers continue to look to recycling as a way to ease the plastic problem. Manufacturing giants claim to be committed to making more of their products and packaging from recycled materials. However, this confidence masks (掩饰) a complex web of issues around plastic recycling. Recycling rates remain extremely low and critics argue that we should look at alternative ways to tackle plastic pollution.
While many plastics have the potential to be recycled, most are not because the process is costly, complicated and the resulting product of a lower quality than the original. Despite rising demand for recycled plastic, few waste companies turn a profit. Part of this is because virgin plastic-linked to oil prices - is often cheaper than recycled plastic, meaning there is little economic incentive to use it. Worse yet, much of our plastic waste is difficult to recycle. Lightweight food packaging, like a mozzarella packet, contains different plastics, dyes and toxic additives (添加剂). This dirty mix means plastic recycled through mechanical methods- the most common form- can only be melted down and moulded (浇铸,塑造) again a couple of times before it becomes too fragile to be reused. And the nature of the process means plastic recycling has a carbon footprint of its own.
Given all of these difficulties, environmental critics say recycling is not the solution-and argue that creating more products from recycled material to attract environmental consciousness merely worsens the problem. “The solution is to use less plastic and to stop misleading the public about the recyclability,” says Enck, president of Beyond Plastics, a US campaign group with a mission to end single-use plastic. “They should stop making false claims about the recyclability of plastics since they know most will either be littered (乱扔) or burned or landfilled (填埋). Using less plastics means shifting to reusable products and relying more on paper, cardboard, glass and metal- -all of which should be made from recycled content.”
