To find out the real reason, the team carried out a first set of experiments in an insect flight area. The researchers used eight high-speed infrared (红外线的) cameras equipped with motion capture technologies to track 30 insects from three moth and two dragonfly species. They also flew lab-raised insects from six different insect orders (生物分类的目) that were too small for motion-capture technology, including fruit flies and honeybees, to make sure different insects all showed similar responses to light. Working with co-author Pablo Allen of the Council on International Educational Exchange in Monteverde, Costa Rica, the researchers put heavy cameras, lights and tripods in two field sites to gather behavioral data from insects in the wild.

The team was able to confirm that insects were not beelining to the light but rather circling it as they tilted (倾斜) in an attempt to turn their backs towards it. This behavior, known as a "dorsal light response", normally helps insects to remain on an unchanging path of flight that is properly lined to the horizon.

Artificial light that arrives from a point source causes them to fly in unpredictable patterns as they try to turn their backs to what they are mistaking for the sky.

Now research might have finally solved the mystery mentioned first: artificial light confuses insects' ability to turn themselves to the horizon, confusing their sense of what is up and down and causing them to fly in circles.

I remember being nervous, aware that we were working with people who were weak and helpless and that I had no idea what I was doing. Some residents were almost nonverbal, some were clearly not with it, some were happy to see us, and some were not.

I had decided to play music at the end of the session. We went with the song My Way because the residents, all roughly 80 years old, would have been listening to the hit song in their late 20s.

Once I pressed play, it was as if a spell had been cast. Nearly everyone in the room stood up and sang what seemed like every word. I was so profoundly moved. Many of them were communicating much better. It looked and felt like magic.

Off I went to drama school, but I thought about that experience almost daily. So when we were given the opportunity to write a script for a theater festival, I created a love story about music and dementia (痴呆), lasting 50 years of a couple's life.

And now, 10 years later, the show I made is running again in London thanks to the Music for Dementia campaign.

When my grandma was diagnosed with dementia toward the end of her life, I didn't struggle to communicate with her in the way that other people in their 20s might have done. I felt more able to tune into what she needed and better equipped to see her underneath the disease.

I now know that music-based treatment reduce the need for antipsychotic medication (抗精神病药物) in more than 60 percent of people living with dementia. I don't know what my My Way would be, but I certainly think we should all strive to find our song and do our best to stay connected to the people we share it with.

When I was in middle school, my social studies teacher asked me to enter a writing contest. I said no without thinking. I did not love writing. My family came from Brazil, so English was only my second language. Writing was so difficult and painful for me that my teacher had allowed me to present my paper on the sinking of the Titanic by acting out a play, where I played all the parts. No one laughed harder than he did. So, why did he suddenly force me to do something at which I was sure to fail? His reply: "Because I love your stories. If you're willing to apply yourself, I think you have a good shot at this."

Encouraged by his words, I agreed to give it a try. I chose Paul Revere's horse as my subject. Paul Revere was a silversmith in Boston who rode a horse at night on April 18,1775, to Lexington to warn people that British soldiers were coming. My story would come straight from the horse's mouth. Not a brilliant idea, but funny, and unlikely to be anyone else's choice. What did the horse think, as he sped through the night? Did he get tired? Have doubts? Did he want to quit? I sympathized immediately. I got tired. I had doubts. I wanted to quit. But, like Revere's horse, I kept going. I worked hard. I checked my spelling. I asked my older sister to correct my grammar. I checked out a half-dozen books on Paul Revere from the library. I even read a few of them. When I handed in the essay to my teacher, he read it, laughed out loud, and said, "Great. Now, write it again." I wrote it again, and again and again. When I finally finished it, the thought of winning had given way to the enjoyment of writing. If I didn't win, I wouldn't care.

The Great Wall of China is one of the greatest wonders of the world. With history of more than 2,000years, some parts of the Great Wall have disappeared., it is still a very popular place of interest.

It is the (long) wall ever built, is about 8 meters high. The top is 8 meters wide and it is even (wide) at the bottom. It is made of stone and brick. People built it hand and it took a long time to finish.

No one knows (exact) when the building of the Great Wall was started. It is believed the wall was built(protect) parts of the country in the old days. It also made people live a safer life.

Today, many of the visitors go to see the Great Wall. When they stand on top of a tower and look down on this wall, they can't help (say), "Wow, that's fantastic!"

Instead of looking at nature, I checked my e-mail. Instead of paddling (划桨) an old boat, I1 my Twitter feed. Instead of reading great novels, I2 reading four newspapers each morning.

And that was the problem: I was acting3 I were still in the office. My body was on vacation but my brain wasn't.

So this year I made up my mind to try something4: getting away from the Internet. I knew it wouldn't be easy, since I'm not good at self-control. But I was determined. I started by5 the iPad to my wife, so I was6 to carry out my plan. Largely7 from e-mail, Twitter and my favorite newspaper websites, I had8 ways to connect to the world except for radio and how much radio can one listen to, really? I had no choice but to do what I had planned to do all along: read books.

This experience has had a happy ending—for now, at least. With9 and the strong support of my wife, I succeeded in my vacation10 against the Internet. I finally11 that it was me, of course, not the iPad, that was the problem.

I knew I had12 when we passed a Starbucks and my wife asked if I wanted to stop to use the Wi-Fi. "Don't need it," I said. However, as we return to post-vacation situation, a test begins: Can I continue when I'm back at work? And I don' t plan to give up my convenience13. But I hope to14 the temptation (诱惑) to check my e-mail every five minutes, which often leads to following my Twitter feed.

A vacation is supposed to help you reset your15 to become more productive(高效的). Here's hoping this one worked.

In today's digital age, protecting your privacy while using apps is important. All apps collect data as you use them. Here are some good tips to keep your personal information safe.

For starters, download apps only from the App Store, not from random websites.

Before you accept an app's terms and conditions, look at what information it's planning to collect and think twice if it's asking for too many permissions. For example, why would a gaming app need access to text messages? You may think it's inconvenient, but it's worth it.

Also, most apps don't need to know your location, but for those that do, you can choose to enable location services only when using the particular app, another smart privacy safeguard.

Don't use your main e-mail address or social media account. This way, if there is a security breach (缺口), your exposure is contained to things connected to that address.

And, of course, use a secure password. This means a long one (at least ten characters) with a mixture of letters, numbers, and special characters—and a unique password for each app. According to security experts, a good trick is to create a memorable "passphrase" by creating a series of random (任意的) words, and then replace numbers or special characters for some of the letters Go ahead and write them down—just store it in a secure location (not your wallet or phone case!).

Finally, remember that privacy is an ongoing concern. Regularly review the apps you have installed and the permissions you've granted them. Stay informed about the latest privacy threats and solutions. By taking these simple steps, you can enjoy the benefits of apps while protecting your personal data.

A. It's better to be safe than sorry.

B. How will you ever remember them all?

C. Why is it so important to protect our privacy?

D. Moreover, create strong, unique passwords for each app.

E. Because it can prevent bad software from infecting your device.

F. Following these four steps will help ensure you're not oversharing.

G. Sign up an e-mail address just for things like app permissions and e-mail newsletters.

Jeffrey Gross, the university science professor who led the research, was not trying to find the relationship between sleep and grades when he handed out smart watches to the 100 students in his chemistry class. Instead, the professor hoped the devices, which track a person's physical activity, would show a connection between exercise and academic achievement.

While Gross's data showed no relationship between these two factors, the study found something surprising. As the researchers were analyzing their data, they noticed that there was a straight-line relationship between the average amount of sleep a student got and their results in the course's 11 quizzes, three midterm tests, and the final exam.

Even more interesting, it was not enough for students to just head to bed early the night before a test. Instead, it's the sleep you get during the days when learning is happening that matters most.

The time students went to bed each night was similarly important. Those who went to bed in early hours of the morning performed poorly, even if the total sleep time was the same as a higher-performing student. "When you go to bed matters," Gross says, "If you go to bed at 10, or 12, or l at night, and sleep for seven hours, your performance is the same. But if you go to bed after 2, your performance starts to go down even if you get the same seven hours. So, quantity isn't everything."

Perhaps the most interesting was the huge impact that small differences in sleep patterns had on the students' grades. The overall course grades for students averaging six and a half hours of sleep each night were 25% lower than students who averaged just one hour more sleep. Similarly, students who varied their bedtime by even one hour each night had grades that dropped 45% below those with more regular bedtimes.

The HeRo robot that is being tested, is a project of Forum Virium, an innovative Finnish company. The trial will be running through the end of December 2023. The goal is to show how packages can be quickly delivered to people's homes with great accuracy even during the holiday season.

HeRo is not just a delivery robot, it's electric and operates without any dangerous emissions, plus it is self-navigating (导航) and talks. The delivery robot was made by the French robotics firm TwinswHeel and uses an interface created by the Finnish company LMAD. The four-wheeled vehicle can carry up to 300 kilograms and can travel up to 20 kilometers on just one charge of its lithium(锂)battery pack. HeRo uses a combination of GPS and onboard sensors(传感器)to run through the city's streets.

HeRo can carry several orders at once. Each order is in a separate locker and customers can open their lockers electronically. In just one hour, the robot delivers packages from a few shops to people in the Ruoholahti and North Jätkäsaari areas. No other delivery service is as fast or as clean.

This isn't HeRo's first appearance on Helsinki streets. From May to August 2023, there was a first phase trial. It carried packages from Würth Center (a place that gives tools and supplies for industry) to nearby workplaces. These trials are part of the international URBANE project. The project wants to find new, green ways to make logistics better for both companies and people. Soon, there will be new trials in cities in Spain and Greece. Using self-driving robots for zero-emission delivery is an idea that should be used all over the world.
