1 . Until recently, gravitational waves could have been the stuff of Einstein’s imagination. Before they were detected, these waves in space time existed only in the physicist’s general theory of relativity, as far as scientists knew. Now, researchers are on the hunt for more ways to detect the waves. “The study of gravitational waves is booming,” says astrophysicist Karan Jani of Vanderbilt University in Nashville. “This is just remarkable. No field I can think of in fundamental physics has seen progress this fast.”
Just as light comes in a variety of wavelengths, so do gravitational waves. Different wave lengths point to different types of origins of the universe and require different kinds of detectors. Gravitational waves with wavelengths of a few thousand kilometers—like those detected by the United States, Italy and Japan—come mostly from pairs of black holes 10 or so times the mass of the sun, or from collisions of dense cosmic blocks called neutron stars (中子星). These detectors could also spot waves from certain types of exploding stars and rapidly moving neutron stars.
In contrast, huge waves that span light-years are thought to be created by orbiting pairs of bigger black holes with masses billions of times that of the sun. In June, scientists reported the first strong evidence of these types of waves by turning the entire galaxy (星系) into a detector, watching how the waves make slight changes to the timing of regular blinks from neutron stars throughout the Milky Way.
Physicists now hope to dive into a vast, cosmic ocean of gravitational waves of all sorts of sizes. These waves could reveal new details about the secret lives of exotic objects such as black holes and unknown parts of the universe.
Physicist Jason Hogan of Stanford University thinks there are still a lot of gaps in the coverage of wavelengths. “But it makes sense to cover all the bases. Who knows what else we may find?” he says. The search for capturing the full complement of the universe’s gravitational waves exactly could take observatories out into the moon, to the atomic area and elsewhere.

3 . Diving in the ocean, marine biologist Erika Woolsey has seen how coral reefs (珊瑚礁) are being damaged by climate change. It has made her decide to find a way to share her experience —including those who can’t easily explore the ocean.
Through her non-profit, The Hydrous, Woolsey is using virtual reality to bring the ocean to everyone. Scientists, filmmakers and divers are taking people on immersive (沉浸式的) virtual dives, attracting attention to reef damage and expecting action to protect our sea. About 25% of marine species depend on coral reefs. However, climate change, pollution and overfishing have done harm to around half the world’s shallow water coral reefs.
Twenty years of underwater exploration has given Woolsey a detailed understanding of the dangerous situations facing reefs. “I’ve seen this first-hand shift. Healthy colourful coral reefs become what look like the moonscape step by step,” Woolsey says.
It is through this experience that The Hydrous team set out to recreate with their award-winning film Immerse. Intended to watch with a VR headset, viewers join Woolsey for a nine-minute guided virtual div e on the coral reefs, immersed in a 360-degree underwater view.
They swim alongside sea turtles and sharks before witnessing the worsening of the reefs. The experience often brings out strong feelings. “As soon as people take off that headset and look me in the eye, they want to tell me a story about their ocean experience,” Woolsey says. “It’s that human connection to our ocean that will solve our ocean problems.”
Woolsey hopes advances in camera technology will allow her team to take more and more people to places in the ocean that are underexplored and places further away from human civilization. They are developing a virtual experience that will put the people in the role of a marine biologist, carrying out biodiversity surveys underwater, and even transporting the viewers to space to monitor global sea surface temperatures.

4 . Coffee is probably the world’s least expensive success power tool. Coffee builds better teams and increases your leadership ability. Coffee also increases your immunity. Unfortunately, we may not be enjoying the benefits or pleasures of coffee too much longer. According to ecologists, there’s a good chance that in 20 or 30 years, the varieties of coffee that we drink today will be extinct (灭绝的). And we’ll be drinking a coffee substitute that more or less resembles the drink we enjoy today.
The problem, of course, is the pace of climate change. Successful coffee cultivation has three preconditions: a warm, highly stable (稳定的) tropical (热带的) climate with altitudes that keep air temperature between 18 and 20 degrees Celsius, rich soil full of natural nutrients, and an ecological environment that’s pest and disease resistant.
Coffee is a crop that is only grown in a thin band called the “coffee belt” close to the equator (赤道). It simply won’t grow anywhere else. Unfortunately, the “coffee belt” is extremely vulnerable to climate change. If the air is too cold or too hot, it prevents the growth of the coffee plant. Climate change also creates environmental stress, which spreads parasites, pests and plant diseases. All of these increase the fragility of the coffee crop and create the possibility of species-destroying rot.
Unfortunately, almost all of these species exist only in Ethiopia, a country that climate change is already hammering. As the environmental nonprofit USAID points out: “Ethiopia is one of the world’s most drought-prone countries. The country is faced with numerous development challenges that exacerbate its weakness facing climate change including increases in temperature, unstable rainfall and unpredictability of seasonal rain, and increased incidences of drought and other extreme events.”
In other words, even as climate change threatens coffee as it exists today, climate change is also eating away at the root source which we might turn to for replacement species.
What to do? Well, take the time to savor each cup of coffee you drink. Beyond that, stop electing the politicians who deny climate change.

5 . The cotton harvest is about to get underway in the Texas High Plains, the windswept region that grows most of the crop in the nation’s top cotton-producing state. But Barry Evans, a third-generation cotton grower, has already walked away from more than 2,000 acres (英亩) of his bone-dry fields. “It just didn’t come up. We hardly had anything,” said Evans.
Extreme heat and a lack of rainfall have severely damaged much of this year’s cotton harvest in the U.S., which produces about 35% of the world’s crop. The U.S. Department of Agriculture (USDA) forecast that more than 40% of what U.S. farmers planted in the spring would be abandoned because of drought. Nowhere is this more apparent than the flat, dry stretch of Texas. The USDA says Texas cotton farmers are likely to abandon nearly 70% of their spring planting. That has been the worst harvest since 2009.
The region normally receives around 18 to 20 inches of rain per year, but saw less than three inches of rain from August through the summer, as nearly all of Texas baked under drought. Much of the cotton grown in the region needs rain. Even those with irrigated (灌溉的) fields are expecting low yields (产量) this year.
The losses in cotton could cost the Texas High Plains $1.2 billion after farmers receive federal (联邦的) crop insurance payments, estimates Darren Hudson, director of the International Center for Agricultural Competitiveness at Texas Tech University. That leaves out others who depend on the crop, such as cotton gins (轧棉机) and storehouses. “Any time you have a bad year in cotton, it has a role to play in the overall economy,” Hudson said.
Fortunately, most cotton farmers in this part of Texas plan to use cotton seed varieties that can resist drought. Varieties are continuously developed and will be adjusted to generate high yields if dry conditions continue. “Even though it’s drought resistant,” Hudson added, “we still have to have a little bit of help from Mother Nature.”

6 . Many strawberry farmers prefer to remove natural habitat around their farms to keep wild birds, and any bacteria they carry, away from their fields and crops. However, a new study published in 2022 shows that farms with surrounding natural habitat experience the most benefits from birds, including less crop damage and lower food-safety risks.
The study was conducted at 21 strawberry fields along California’s Central Coast. It found that birds were more likely to carry bacteria and eat berries without surrounding natural habitat.
For the study scientists looked at the analysis of 1,000 fecal (排泄物) samples from 55 bird species, combined with previous data from more than 300 bird surveys. They used the information to figure out what each bird was eating - be it pests, beneficial insects or crops-as well as which birds were carrying bacteria. Using this data, the scientists then ranked wild birds to see which were more likely to bring most benefits or costs to farmlands. Barn swallows, for example, were ranked beneficial to farmland.
But the results were more than creating a list of “good” and “bad” birds. The study found that most bird species brought both costs and benefits to farms, depending on how the surrounding land was managed. That was the single most important factor differentiating a farm where wild birds brought more benefits than harm. And farms with surrounding natural habitat for birds constantly saw less damage and fewer bacteria problems than others.
Moreover, the study was part of a series of research conducted in Daniel Karp’s lab at University of California, Davis, all focusing on the impact and importance of maintaining natural habitat for wildlife surrounding farmland. A related study in 2020 also found that farms with natural habitat attracted more insect-eating birds and fewer strawberry-eating birds.
Thanks to the studies, farmers experience less berry damage on farms with more habitat nearby.

7 . The Sequoia National Park in California’s southern Sierra Nevada mountains is best known for the Giant Forest, a collection of 2,000 trees that includes half of the Earth’s largest and longest-living trees. This past weekend, the ancient wonders came dangerously close to being burned by the KNP Complex Fire. But thanks to resourceful firefighters, the precious treasure has been saved.
The firefighters had taken the standard measures of clearing brush and setting controlled fires long before the fire began heading toward the Giant Forest. But they knew more needed to be done. On September 17, 2021, they took the unusual step of covering the base of some of the oldest trees with protective aluminum “blankets”. High on the list was General Sherman, the world’s largest tree by volume. The park officials believed the specialized foil(锡纸)would help block some of the heat from the fires and enhance the natural insulation(隔热)provided by the ancient trees’ thick bark. They were right!
On Sunday, September 19, 2021, the officials reported that the extra prevention measures, which also included 24-hour timed sprinklers(洒水装置)on General Sherman and the nearby park buildings, had worked. Jack Owen, a spokesman for the KNP Complex Fire Information Office, said, “There are no trees that have been burned yet, as far as in the Giant Forest. Firefighters are pouring everything they can into it as long as it’s safe. That area is looking good.”
Unfortunately, the same cannot be said about the rest of the national park. The KNP Complex Fire has burned through 21,777 acres. Meanwhile, the Windy Fire, which started further south on the Sierra slopes on the same night, has burned over21, 598 acres. Hopefully, the weather will cooperate and allow firefighters to gain control of the massive fires, which are now beginning to threaten nearby communities.

8 . When we drove through a twenty-foot-tall fence and entered the Okonjima Camp in central Namibia, the first question on our minds was whether the fence was being used to keep animals in or out. Our guide was quick to say, “Out.” The Okonjima Camp works with the AfriCat Foundation that accepts injured big cats. So there was no shortage of cats, and on that first night, we heard growls (咆哮) from our houses. How close we were! I hope nobody left the gate open.
The next day of our Africa trip started with a journey outside the fences and protected zone to track a mother leopard (花豹) and her baby the guide had seen the previous day, and we were happy to find them very quickly. The mother leopard was aware of our presence but was relaxed since our car was a healthy distance away, and we sat for 45 minutes watching the sweet interactions between mother and baby.
Later in the day, the guide said we would go on a hike. Everything we were told before about staying in the vehicle and not leaving the fenced arca of the camp was put aside. We were going to find cheetahs (猎豹). It is safer to approach cheetahs, keeping a safe distance, and our guide got out earphones to listen on the leopards’ radio collar (颈圈) frequency to see if any were in the area. No leopards, no problems. Let’s go look for cheetahs, and we did find them. Well, I didn’t. Our guide’s tracking skills were phenomenal. He quickly found them somehow lying in the shade of some tall grass. After some time, they stood up on their long legs. No cheetah-fast speed, but a silent walk into the bushes (灌木丛).

9 . Across the world, animals including bears, moose, lynx, squirrels and frogs are leaving their homes as the planet warms.
A study was done of more than 4,000 species from around the world. It showed that about half of them are on the move, according to National Geographic. They are moving up slopes and away from the equator toward the poles to seek cooler environments. The ones on land are moving an average of more than 16 kilometers per decade, while marine species are moving four times faster.
Mountain species in particular, “are struggling to keep pace” with global warming, said Shaye Wolf, climate science director at the Center for Biological Diversity in the US. In North America, for example, pikas used to climb an average of 13 meters per decade but it has gone up to 145 meters per decade since the late 1990s. Similarly, moths on Mount Kinabalu in Borneo, an island in the Pacific Ocean, moved up 67 meters in altitude to escape rising temperatures. “We’re concerned many species won’t be able to move quickly enough, or that they will run out of mountaintop to flee,” said Wolf.
In some cases, moving species can lead to big changes in the whole ecosystem, as such areas aren’t able to deal with it. In Australia’s seas, kelp forests are being destroyed by tropical fish that have come in to eat them, threatening the survival of rock lobster, which also feeds on help forests.
And this is just adding fuel to the fire, making climate change worse. Take the pole ward spread of bark beetles in northern hemisphere forests as an example. The beetles attack trees that might already have been weakened by warmer, drier conditions, leading to more pest outbreaks and tree deaths. These, in turn, provide more fuel for forest fires, releasing more planet-warming carbon dioxide.
Climate-driven species’ movement shouldn’t be a concern only for scientists — it should worry everyone, Nathalie Pettorelli, at the Zoological Society of London, UK, told the Guardian. “The world as a whole isn’t fully prepared to deal with the range of issues emerging from species moving across local, national, and international boundaries”.

10 . It takes courage to live on Montana’s short-grass prairie (大草原). The native people successfull, adapted to the difficult environment over many centuries. For the last 150 years, wild animals have given the basic habitat up to cows, which makes this rare habitat decline ecologically.
Today, though, parts of the landscape are being shaped by a different resident—the North American plains bison (野牛). Tribes and conservation organizations have recently started bringing the bison back. And scientists studying the returns are discovering that getting the 900 kg grazer back in its native ecosystem could be a key to the future of the prairie.
An adult bison eats about 11 kg of grass a day. The grasses adapt to their search for food. Vegetation across the plains uses the nutrients in their waste. Birds pull out their fur from bushes to keep the heat of nests from passing out.
Bison also shape the land literally. They roll in the dust and create muddy areas that hold water after rainstorms. After the bison move on, insects flourish in these pools and become a feast for birds and small mammals. Pronghorn antelope survive by following their tracks through deep winter snows.
Plains bison spent thousands of years engineering a distinctive grassland ecology from Northern Canada through Montana to Mexico. But more than a century ago, this influence suddenly stopped. A few decades of killing led the number of bison to fall suddenly from 60 million to barely 800 living wild in the US and Canada by 1889.
Today, however, bison are getting a second chance. Tribal reservations are at the forefront of their recovery, taking extra bison from Yellowstone National Park and restoring them to treaty lands. Now some scientists are keeping close watch on the changes of the lands after the return of bison.
