1 . If you look at the dynamic “Global Temperatures” map on NASA’s website, you can see the historic temperature change over time across the planet as the timeline goes from 1880 to the modern day. By 2019, the entire planet is in red, orange, and yellow colors, indicating temperatures much higher than the historical average in every country and human inhabitance.
If the timeline went to 2023, the map would look even worse. That’s because the summer of 2023 was the hottest ever, according to ocean monitors. July was the hottest month in recorded history. Next July could be worse. Unless we do something quickly, we face dealing with more and more dangerous and expensive natural disasters in the future.
Forest fires sent smoke from Canada across the North American continent, causing New York City to have the worst air quality in its recorded history. Heavy rainstorms fell on Vermont and the Northeastern United States in just a couple of days in the middle of July, which exceeded the amount that area would usually receive in two months and caused extreme damage to homes and businesses. Around the same time, flash flooding in Bucks County, Pennsylvania — north of Philadelphia — killed nearly a dozen people.
Erich Fischer, a researcher specializing in climate studies at the Swiss Federal Institute of Technology, is concerned that natural disasters could get much worse in the future—and in ways we cannot predict. He called for a “strike for climate justice,” which actually took place on Sept. 15, 2023. “The strategy needs to be twofold (双重的) . We need to decrease carbon emissions as much as realistically possible. That is already happening with people using electric cars and other green technologies. At the same time, we also need to find ways to predict the risk of natural disasters ahead of time,” said Erich Fischer.

2 . Some of our planet’s power pollinators (传粉昆虫) may have originated tens of millions of years earlier than scientists once believed. In a study published July 27 in the journal Current Biology, a team of researchers traced bee family back over 120 million years to the ancient supercontinent Gondwana (冈瓦纳大陆). While looking deeper into bee history, the team found evidence that bees originated earlier, diversified faster, and spread wider than previously suspected, putting together pieces of a puzzle on the origin of these pollinators.
In the study, an international team of scientists would be in sequence and compared genes from over 200 bee species. They then compared these bees with the traits from 185 different bee fossils and extinct fossils to develop an evolutionary history and genealogical model for how bees have historically been spread around the world. The team was able to analyze hundreds of thousands of genes at a time to make sure that the relationships they inferred were correct.
“This is the first time we have broad genome-scale data for all seven bee families,” study co-author and Washington State University entomologist Elizabeth Murray confidently said in a statement. Earlier studies established that the first bees potentially evolved from wasps (黄蜂), transitioning from predators up to collectors of pollen and nectar (花蜜). According to this study, bees arose in the dry regions of western Gondwana during the early Cretaceous period, between 145 million years ago to 100.5 million years ago.
“There’s been a long-time puzzle about the origin of bees,” study co-author and Washington State University entomologist Silas Bossert said in a statement. “For the first time, we have statistical evidence that bees originated on Gondwana. We now know that bees are originally southern hemisphere insects.” The team found evidence that as new continents formed, the bees moved northward. They continued to diversify and spread in parallel partnership with flowering plants called angiosperms. The bees later moved into India and Australia and all major bee families appear to have split off from one another before the beginning of the Tertiary period (65million years ago).

3 . Established earthquake warning systems provide at best just a minute or two of notice, leaving little time for preparedness. Decades of searching for a better warning sign-changes in the geochemistry of groundwater, electromagnetic effects in the upper atmosphere, and even changes in animal behavior-have failed. Many question whether such a precursor (先兆) even exists. This situation may change soon, as recent research is providing a glimmer of hope for improved earthquake prediction.
Researchers Quentin Bletery and Jean-Mathieu Nocquet from Cote d’Azur University in France collected data from over 90 earthquakes with magnitudes larger than 7 that had occurred in the past two decades.They focused on GPS station records near these quakes, which accurately captured land movement every 5 minutes with millimeter precision. They analyzed more than 3,000 time series of motion in the 48 hours leading up to the main ruptures (断裂).
They noticed that, in the first 46 hours, the records showed no significant features. However, during the 2 hours before the earthquake, they noticed signs of increasing movement along the fault zones (断层带). Essentially, there’s a slip between plates causing the land above them to move in a measurable, horizontal direction.
Could this be just a coincidence? The probability of this increase happening just before the quake and being unrelated is extremely low, and the researchers confirmed this by analyzing 100,000 random time windows in non-earthquake GPS data. The pattern occurred only 0.03% of the time in non-earthquake data.
While this precursor signal won’t be used for warnings anytime soon, officials from the United States Geological Survey (USGS) admit that this new study provides valuable insights into how to improve their warning systems-GPS data can grease the wheels of early earthquake warnings.
The researchers admit they're still a number of steps away from putting this precursor signal into use, particularly since detecting subtle signals at individual faults requires more GPS stations. But the biggest problem is that many of the world’s earthquake regions have no instrumentation. “We can’t realize the detection at the scale of one earthquake, so we cannot make predictions,” Bletery said.

4 . A team of researchers from the University College London (UCL) has recently found that humans transmit viruses to domestic and wild animals more frequently than they contract them from these animals. This major analysis of viral genomes offers new insights into the dynamics of disease transmission across species.
Through an exhaustive examination of all publicly available viral genome sequences, the experts aimed to trace the cross-species transmission—or host jumps—of viruses.
The team sought to challenge the prevailing view that humans are primarily at the receiving end of zoonotic diseases, which are infections that jump from animals to humans. These diseases have been responsible for outbreaks such as Ebola, flu, and COVID-19.
The research team developed and applied methodological tools to analyze the nearly 12 million viral genomes that have been published on public databases to date, outlining the scale of their investigation into the evolutionary paths and mutations of viruses as they adapt to new hosts.
Contrary to the common perception of humans as mere recipients of animal viruses, the study’s findings suggest a more bidirectional exchange of pathogens (病原体). “We should consider humans just as one node in a vast network of hosts endlessly exchanging pathogens, rather than a sink for zoonotic bugs,” said co-author Francois Balloux, a professor at the UCL Genetics Institute.
“By surveying and monitoring transmission of viruses between animals and humans, in either direction, we can better understand viral evolution and hopefully be more prepared for future outbreaks and epidemics of novel illnesses, while also aiding conservation efforts. ” Study lead author Cedric Tan, a PhD student at the UCL Genetics Institute and Francis Crick Institute, pointed out the broader implications of their findings, especially concerning conservation and food security. “When animals catch viruses from humans, this can not only harm the animal and potentially pose a conservation threat to the species, but it may also cause new problems for humans by impacting food security if large numbers of livestock need to be killed to prevent an epidemic, as has been happening over recent years with the H5N1 bird flu strain.”

More than 20 hours earlier, my friend Emma and I had stood at the entrance to the cave. We laughed and joked as I climbed down the steep mouth and she followed. Six of us had gone on that camping trip, but after a full day of exploring caves, the others had gone back to the campsite to eat. Emma and I decided to explore one more cave.
The mud of the cave floor was soft and sticky as we snaked our way through the tunnel. The air was damp and heavy. As the passage twisted through the earth, it became smaller. Then, suddenly, after a tight squeeze, I came into a larger room.
“Once you make it past this narrow spot you can almost stand,” I told Emma, as I stretched out my arms and legs and enjoyed the big space. “Alright, I’m almost th...” Emma’s sentence was cut short. I turned around. “Are you alright?” I asked. All I could see was her face, and her eyes were full of fear. “I don’t think so,” she said. “I’m stuck.”
Emma and I tried everything we could to free her. But it became apparent that we needed help. I took out my cell phone to call my other four friends, but there was no signal. I couldn’t go to seek help because Emma was stuck between me and the cave mouth. That was why we were so relieved when we heard voices behind us. A beam of light shot down the tunnel.
“What’s going on here?” rang a young man’s voice. “We need help,” I shouted. “She’s stuck.” “I’ve got two buddies with me,” he said. “They can go to find a park ranger (公园管理员), but I’ll stay here and see if I can help from this side.”

Nancy Lowe. 5, from Walton-on Thames, England, experienced the loss of her beloved cat, Tintin, earlier this year. She died from heart failure and Nancy had been struggling to adjust to life without her best friend. Concerned and anxious, Nancy’s mom, Tamara, said, “Nancy and Tintin were best friends, and they had a really close bond, Whenever they saw each other, the two of them were so happy.”
Nancy desperately missed Tintin and she was worried the cat would be lonely, so she decided to write a letter to her cat up in heaven. She was warned by her mother, who told her that heaven might be too far away and that Tintin might have found a new friend, but Nancy insisted on writing the letter. When she was asked what she had written, she showed the letter to her mother generously. It read, “Dear Tintin, I miss you. Have you found a new friend in heaven?” Tamara was touched by her daughter’s sincere love and kindness. She didn’t want to disappoint her daughter so they posted the letter together.
Before they put the letter in a post box, once again Tamara tried to let her know she probably wouldn’t receive a reply, but Nancy addressed the envelope to “heaven” and mail edit off anyway.
Tamara said, “When we sent the letter I didn’t expect anything to comeback and I don’t think Nancy did, either. But it was important for her to say a proper goodbye. Getting a response was the last thing we expected.” Tamara and Nancy didn’t know a postman named Clive Edwards was on duty that day and he saw the letter addressed to heaven and wanted to help Nancy find some comfort in her loss.

___________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________My best friend, Cocoa, and I live in a senior-citizen apartment complex in a lovely small town. Cocoa is a ten-year-old poodle(卷毛狗) and I am a sixty-nine-year-old lady, so you can see we both qualify as senior citizens.
Years ago, I promised myself that when I retired I would get a chocolate poodle to share my golden years. From the very beginning, Cocoa has always been exceptionally well-behaved. I never have to tell him anything more than once. He is extremely neat—when taking toys from his box to play, he always puts them back when he is finished. I have been accused of being obsessively neat, and sometimes I wonder if he mimics me or if he was born that way, too.
He is a wonderful companion. When I throw a ball for him, he picks it up in his mouth and gives it back to me. He does many amusing things that make me laugh, and when that happens, he is so delighted that he just keeps it up. I enjoy his company very much.
But almost two years ago, Cocoa did something that challenged comprehension. Was it a miracle or a coincidence? It is certainly a mystery.
One afternoon, Cocoa started acting strangely. I was sitting on the floor playing with him when he started pawing and sniffing at the right side of my chest. He had never done anything like this before, and I told him, “No.” Usually, one “no” is sufficient, but not that day. He stopped briefly, then suddenly ran toward me from the other side of the room, throwing his entire weight—eighteen pounds—at the right side of my chest. He crashed into me and I yelled in pain. It hurt more than I thought it would have.
Soon after this, I felt a lump (肿瘤). I went to the doctors, and after X-rays, tests and lab work were done, they told me I had cancer.

Architects often spend months or even years perfecting a design to express their ideas more clearly, convey additional information, or outline the right proportions for a building. However, the urgent issue of climate change is placing new demands on their work. For example, in July, Super Typhoon Doksuri battered China, affecting more than 2.66 million people in Fujian Province alone.
Green architecture that conserves energy and reduces carbon dioxide emissions offers a solution, and concerted efforts have been made in diverse research fields over the past three decades to minimize heat loss. In addition, new buildings have to be tailored to the needs of people’s lifestyles.
Ren Jun, a professor at Tianjin University’s School of Architecture, who designed the first near-zero energy house in China in December 2019, said, “You can construct low-energy, environmentally-friendly houses, but if the interior design and environmental quality don’t meet residents’ requirements, these properties won’t be suitable to live in.”
The near-zero energy house, located-in Banbidian village in Beijing’s southern district of Daxing, won the International Design Award in the United States in January last year. The 400-square-meter property, which stands at the entrance to the village, runs on solar power gathered from rooftop panels, with the addition of a small amount of power from the grid (电网).
Ren said the first obstacle to conserving energy in the property was heat retention, which he attempted to achieve by keeping the indoor temperature at a certain level. The property is divided into five areas: a solar garden in the front yard, a central lounge, a water courtyard, a sponge zone, and a back room. For the exterior walls, Ren used three types of insulation (隔热层), including plastic foam, each about 25 centimeters thick.
Ren also looked for ways to deal with emissions at the house. He decided to install a ventilator, which pipes air that is polluted and replaces it with fresh air from outside in every room at the property.
Ren said it would take three to five years before more ultralow or near-zero energy buildings appeared in Chinese cities.

9 . Bumblebees are vanishing at a rate consistent with widespread extinction, and climate change is playing a big role. The analysis comes from a new study published in the journal Science today.
The authors found that the likelihood of a bumblebee population surviving in any given place within North America and Europe has dropped by an average of 30 percent as temperatures have risen.
Pesticides, habitat loss, and pathogens(病原体) have already hit bumblebee populations hard. The new study, however, is able to isolate the effect that hotter temperatures are having on bumblebees. Sadly, bees are having a hard time adapting to a warming world. “If things continue along the path without any change, then we can really quickly start to see a lot of these species being lost forever,” lead author of the study Peter Soroye tells The Verge.
That’s not just a tragedy for the bees. It’s also bad news for all the plants that they pollinate and for humans who eat the fruits (and vegetables) of their labor. “We also lose out on a lot of color on our plates,” Soroye says. “Tomatoes, squash, and berries are just some of the crops we can thank bees for pollinating. Animal pollinators like bees, birds, and butterflies could be responsible for up to 1 out of every 3 bites of food we eat,” the US Department of Agriculture says.
For this study, Soroye and colleagues examined data from 1900 to 2015 on 66 species of bumblebees across North America and Europe. They mapped the places bees called home and how their distribution changed over time. They found that bees were vanishing in the areas that had heated up beyond the limit in which the bumblebees had historically been able to survive.
Some bee populations are colonizing new territories that were previously too cold. But those gains are overshadowed by losses in areas where the bees once thrived but are now too hot.

Tom is a special child. Ever since he was little, dogs have been his greatest passion. He often growled (低吼) and barked and sometimes moved around the house on all fours. His parents brought in a little brown female dog named Lynn. Tom was on cloud nine. One day, this little boy, together with Lynn, was sitting quietly down by the side of the street when suddenly a giant dog walked across him. He was a little surprised and started screaming as loudly as he could! All of this frightened Lynn away immediately.
Tom’s parents tried to see what the chances were of Lynn coming home on her own. But five days later, there was still no sign of Lynn. The boy didn’t just have tears streaming down his cheeks — his parents were saddened too.
The woods behind their home stretched for over 50 miles! Together with their neighbors, they searched for over a month. But Lynn was gone. Tom’s parents wanted to choose a new puppy for him. But no dog could replace Lynn for him.
Tom was not the same boy. He locked himself in his room. He seemed to have lost his love for dogs. He could not focus his attention on his classes so he didn’t want to go to school. He would easily get angry with people around him. Tom changed from a happy, smiling boy to an upset and annoying kid.
Tom’s parents wanted him to stay home and he had been studying at home ever since. His parents accompanied him almost every day, but staying home didn’t help much. The boy’s mother worried a lot. One rainy afternoon, she saw him staring out the window. “I miss Lynn so much. I wonder if everything is okay with her?” It had been a long time since his beloved dog ran away, but Tom’s despair was as great as the day it happened. Days later, Tom walked out the front door with his head down and sat by the side of the street.
