With the click of a button, Amanda Eshelman, a 13-year- old girl with hearing loss, regained the ability to hear the world around her.

"Hi, baby, " her mom, who seated herself next to her at St.Louis Children’s Hospital, said before they both burst into tears.

Amanda has been deaf in her left ear from a young age and has been progressively losing hearing in her right ear since she started middle school two years ago.A hearing aid helped her for a while, but it slowly became less and less effective.

A specialist in St.Louis Children's Hospital thought a cochlear implant could improve her hearing—but there was no guarantee.Her parents allowed Amanda to decide for herself.She wanted to go for it.

"They said she hadn’t heard on this side for at least 10 years； we didn't know if it would work, and if her brain would be able to recognize these signals," Amanda’s mom, Betsy Eshelman, told Today.“So we tried not to get our hope up as we walked in.”

In mid-November, Amanda had the surgery and two weeks later, the system was turned on.When the sounds returned，Amanda covered her mouth with her hands in astonishment and then shed tears of joy.

“I like it, ” Amanda said in the video.“It’s a lot better than I thought it was going to be.”

Amanda noted the whirr of the fan system and the buzz of the lights overhead.“I didn’t know the lights make noise.”she said.

Now, Amanda is able to hear all sorts of sounds she has been missing out for years—especially at home.

"It's been great，" Betsy said."She made the comment that she didn’t realize how loud we all were! She didn’t realize how quiet her world had become.”

On Sunday, Tigst Assefa of Ethiopia shocked the running world by breaking the women’s world record for the marathon by over two minutes. Assefa finished the Berlin Marathon in just 2 hours, 11 minutes, and 53 seconds.

But Assefa’s record was far beyond what most people expected. After all, it was only her third time running a marathon.

“I wanted to break the marathon world record,” she said, “But I couldn’t imagine that it would result in a time under 2:12.”

When Assefa was younger, she started by running short races, called sprints. Then she became a middle-distance runner, running the 800 meters (half mile) race. Her best time in the 800 meters was 1 minute and 59 seconds.

Last March, she ran her first marathon. Then last September, she entered the Berlin Marathon. She won, and set a new women’s record for the course, finishing in 2:15:37.

This year, she ran almost four minutes faster than she did last year. In both races, Assefa ran faster in the second half of the race than she did in the first half.

Her time of 2:11:53 was over two minutes faster than the old women’s record (2:14:04), which was set in Chicago in 2019 by Brigid Kosgei of Kenya.

When she finished the race, Assefa kneeled down and kissed the pavement before raising her arms in victory.

Though Assefa made it look easy, she said winning the race “…was the result of hard work.” Assefa was coached by Gemedu Dedefo, who has helped train many Ethiopian star runners.

According to related new research, tropical cyclones(热带气旋), ranging from hurricanes to typhoons, are moving more slowly across the planet than they did decades ago, meaning that they get more destructive power and last longer.

It may seem like a good thing that cyclones crawl at a slower speed, but in fact it’s quite the opposite. Although the cyclones are moving slower across the ground, they still get high wind speeds inside, which on the contrary makes hard rains stay longer over communities.

“Nothing good comes out of a slowing storm,” says James Kossin, with the National Oceanic and Atmospheric Administrations Center for Weather and Climate in Madison, Wisconsin. “It can increase storm surge. It can increase the amount of time that structures are subjected to strong wind. And it increases rainfall.”

According to Kossin’s findings, changing storm patterns are causing greater destruction in another way. He noted that the speed of global tropical cyclones slowed by an average of 10 percent from 1949 to 2016. The pace of the storms slowed even more as they made landfall in some regions. In the western North Pacific, it declined by nearly a third. That means there will be more time for a storm that may already contain much moisture (水汽) to release more of it in each spot.

Basing his research on the details of nearly 70 years’ worth of storms, Kossin did not try to determine the cause of the slowdown. Even so, the shift is, exactly as he and other cyclone experts said, the expected result of climate change.

Kossin’s work was considered to be “pretty convincing” by Christina Patricola, a scientist with the Climate and Ecosystem Sciences Division of California’s Lawrence Berkeley National Laboratory.

It is Kossin’s hope that a model demonstrating which communities are likely to be at the highest risk could be developed by scientists. Given that in some regions, the storms are moving poleward and gaining in strength as well, places not normally passed by could be affected by unusually heavy rainfall as a result. “These are not good things to be combining,” he says.
