2 . Some of the oldest living things on our remarkable planet are trees. The record holders are bristlecone pines (狐尾松) of the western United States, quite a few of which are known to be more than 3,000 years old. One individual, discovered in 2012, is estimated to be more than 5,060 years old, making it the oldest known non-clonal tree in the world!
So, how do trees survive for thousands of years?
The other part of the answer has to do with how trees age. In fact, there is quite a debate about whether ancient trees can be considered “immortal (永生的)”. That is, will such trees ever die if they are not killed by an outside force? We may never know the answer to that, but, at the very least,
Older trees benefit greatly from having bodies made mostly of dead woody tissue. In fact, an old tree might be as much as 95 percent dead tissue! Given that it isn’t alive, wood does not require metabolic (新陈代谢的) activity to maintain it,
A.so an old tree doesn’t really need to do much to keep living |
B.This is a question that has something to do with the good luck of trees |
C.However, bristlecones are certainly not alone in terms of the oldest creatures |
D.This is a fascinating question for biologists that does not yet have a settled answer |
E.What’s more, some ancient trees have superior chemical defenses against pests and diseases |
F.which means that trees can survive everywhere without being limited by external and internal conditions |
G.we know that ancient trees age in ways that are dramatically different from the ways that most animals and even other plants age |
3 . 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.

4 . 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.”

6 . 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.”

7 . 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.
