A brave dog fought off a coyote (丛林狼) twice her size to protect her 10-year-old owner after it attacked them. Owner Lily Kwan, 10, said she had just heard her neighbors in her Toronto, Canada community on Tuesday warning people of a coyote going after children in the area when the animal started biting at her heels while she was walking dog Macy.
In the video captured by a neighbor’s security camera, Lily can be seen running down the sidewalk with her six-year-old rescue dog while the coyote followed them so closely.
“I thought, ‘Am I next, what is going to happen to me?’” Lily told the local newspaper. “I was screaming for help but no one heard me,” said Lily. “I saw this coyote trying to attack my dog and I tried to ring people’s doorbells and knock on people’s doors. Luckily, this one neighbor let me in.”
But while Lucy made it to safety, Macy wouldn’t follow her inside. Instead the little dog turned around toward the coyote. After briefly screaming Macy’s name, Lily ran onto the neighbor’s second floor. Macy could be seen fighting with the coyote, before it caught her and bit her in its mouth and shook her violently. She cried in pain, but kept barking and bit the coyote back until it gave up and ran away finally.
“She’s a super brave dog,” Lily said “I love her so much, and I just thought this tiny dog could protect this huge human being, trying to fight off this huge coyote.”
Lily’s mother, Dorothy Kwan, said she was not surprised when hearing Macy’s action. “My dog would do anything for our family, so I’m actually not surprised that she did that,” Dorothy Kwan said.

2 . In gardens across Britain the grass has stopped growing, which is not drought-stricken. In fact, it is greener and cleaner than ever before. That is because the lawns (草坪) are actually artificial substitutes.
Britons are fascinated by lawns. Country estates (庄园) have long competed to have the most perfectly cut and polished grassland. “What you’re saying in big loud capital letters, is ‘I’m so terribly wealthy’,” says Fiona Davison of the RHS (皇家园林协会). With the coming of grass-cutting machines in 1830, the middle classes joined the fun.
But now Britons have fallen in love with artificial grass. Evergreens UK, which sells the stuff, says it has seen a 120% rise in sales since 2015. Artificial grass is popular with families who have children or dogs and don’t want mud dragged through their houses. It has another charm factor, too — people now see gardens as “outside rooms” — pairing carpets of artificial grass with delicately decorated seating and hot containers.
Not everyone is a fan. Artificial grass contains microplastics that ruin soil and risk flooding. A study finds earthworms gain 14% less body weight when operating under rubber, a form of artificial grass, which might not be a problem for its fans, as wormholes are regular disgusting things, but it disappoints green types. Ms Davison says a group of wildlife-loving gardeners is blooming, many having caught the bug during COVID-19 lockdowns. For example, a landscape designer says they like things less neat and try “to capture that wild element”. These eco-gardeners are influenced by rewilding projects and are more likely to be environmentalists.
While three written documents signed by many people have tried to stop artificial grass spreading, the government says regulating what people do in their backyards is wrong. The RHS is concerned about artificial grass, but prefers persuasion to laws. “We say ‘Let a hundred flowers bloom’,” says Ms Davison.

3 . The 1930s and early 1940s were a good time to fish for sardines (沙丁鱼) off California. Centered on Monterey Bay, catches increased dramatically and supported the state’s economy. But the situation began to change in 1946, and sardine catches eventually fell from an average of 234,000 tons to just 24,000 tons. The industry went belly-up.
Scientists have guessed for decades about what caused this phenomenon, but they lacked data to test their theories. Now researchers have finally found one apparent cause: cycles of ocean upwelling, a defining feature of the West Coast sea environment in which deep, nutrient-rich water rises to the nutrient-poor surface and restores the food supply there. The key that unlocked this phenomenon turned out to be old seaweed specimens (标本) gathered around the U. S.
“Plants are just sitting there, recording data about the state of the ocean,” says Kyle Van Houtan, chief scientist at the Monterey Bay Aquarium and senior author of the new study. Van Houtan and others had suspected the impact of upwelling, but scientists only started measuring the process in Monterey Bay in 1946. Historic seaweed specimens, Van Houtan realized, might fill in the blanks for earlier years—similar to the way ice cores can help reconstruct CO2 levels from times before researchers started collecting real-time measurements.
For the new study, the scientists relied on the fact that deeper water near Monterey typically hosts more of a particular nitrogen isotope (氮同位素). Looking at modern upwelling data and recently collected seaweed, they found that higher levels of this nitrogen in the plants’ cells corresponded with periods of more upwelling. Next they measured the isotope levels in 70 historic specimens of the red seaweed Gelidium, gathered from Monterey as far back as 1878. The results suggested a gradual increase in upwelling and then a dramatic decrease, which lined up with the sardine population’s growth and decline.
“This paper is an excellent example of the creative detective work of historical ecology,” says Loren McClenachan, a marine ecologist at Colby College, who was not involved in the research. “There are thousands and thousands of similar specimens in collections around the world, and applying similar methods could teach us a great deal about long-term ocean change.”

A freezing downpour washed the street in front of the small-town bar. I sat gazing into the watery darkness, alone as usual. I had been in that old bar for half an hour, quietly drinking, when my thoughtful eyes finally focused on a medium-sized lump (一团) in a puddle (水洼) a hundred feet away. For another ten minutes, I looked out through the window trying to decide if the lump was an animal or just something.
The night before, a German dog named Shep had come into the bar begging for potato chips. He was starving and just the size of the lump in the puddle. Why should a dog lie in a cold puddle in the freezing rain? I asked myself. The answer was simple: Either it wasn’t a dog, or it was, he was too weak to get up.
The wound in my right shoulder ached all the way down my fingers. I didn’t want to go out in the storm. Hey, it wasn’t my dog. It was just a stray on a cold rainy night, a lonely drifter (流浪者). So was I, I thought, as I tossed (扔) down what was left of my drink and headed out the door.
He was lying in the three inches of water. When I touched him, he didn’t move. I thought he was dead. I put my hands around his chest and raised him to his feet. He stood unsteadily, and his head hung like a weight at the end of his neck. His floppy ears were just hairless pieces of flesh dotted with open sores (伤口).
“Come on, Shep,” I said, leading him to a corner next to the bar, where he lay on the cold cement and closed his eyes. A block away I could see the lights of a late-night convenience store. It was still open. I bought three cans of dog food and fed him. He couldn’t swallow but poorly look at me. He was dying!

8 . China has successfully landed its rover on Mars, becoming the second country in history to have a rover on the red planet.
The rover, Zhurong, named after a god of fire in Chinese mythology, landed Saturday morning at the pre-selected area in Utopia Planitia on Mars. The six-wheel solar-powered Zhurong rover weighs about 240 kilograms (529 pounds) and carries six scientific instruments. It will be later released from the lander for a three-month mission in search of life on Mars' surface.
Tianwen-1, whose name means “Quest for Heavenly Truth,” will relay its signal to the rover during its mission and then conduct a global survey of the planet for one Martian year. It hopes to gather important information about the Martian soil, geological structure, environment and atmosphere, and to search for signs of water. The probe has spent three months in orbit scanning the landing area before releasing the rover to the surface, and sent back its first photo of the planet from more than a million kilometers (621,371 miles) away.
Tianwen-1 was launched by a Long March 5 rocket from the Wenchang space launch center in Hainan on July 23 last year, and spent seven months on the way to Mars before entering its orbit in February. “The probe is going to orbit, land and release a rover all on the very first try, and cooperate with an orbiter in observation,” the scientific team behind Tianwen-1 said before the rover's landing. “No planetary missions have ever been implemented in this way”.
Tianwen-1 is one of three international Mars missions launched last summer due to an alignment between Earth and Mars on the same side of the sun, making for a more efficient journey to the red planet. Unlike the US and China missions, the UAE probe is not intended to land on Mars---just study the planet from orbit.

10 . Nobody wants to snack on plastic bags or soda rings, but according to a recent study from the University of Neweastle, we could be consuming roughly a credit card's worth of plastic every week.
Microplastic, which are less than a quarter-inch size and come in various shapes, have polluted the natural world and infiltrated(渗入)our bodies. The first clue to microplastic exposure in humans came around 2013, when scientists discovered plastic particles in seafood prepared for consumption. But in 2019, when the University of Newcastle study was published, the scientific community understood that the problem was considerably broader. Microplastics shed off clothes and tires and have been found in beer, honey, table salt and other food items. We breathe in plastic staying in the air and drink plastic floating in our drinks. It's no stretch to conclude that our exposure is significant. What we don't know is what this means for us.
The amount of evidence collected on this subject is growing rapidly, according to Scott Coffin, a toxicologist(毒理学家). Studies done on mice and rats have found that plastic in their bodies can severely damage cells and cause stress.
Because microplastics are too small to clean up, the only solution is to stop plastic waste at the source. And doing so would take a thorough adjustment, given that plastics are deeply embedded in our economy and lifestyle. Stopping using them would fundamentally affect countless industries, including textiles(纺织业), transportation and manufacturing.
"I think we need to have more studies coming out that are directly related to human health before we see a lot more concern from the general public," Scott said. "It takes a lot to convince people that something that is really convenient for them to use is something they should sacrifice."
The question of microplastics and human health needs more attention—from the scientific community ,the general public, the government and funding groups. The issue isn't being ignored, but it's not being prioritized either.
