1 . For people, who are interested in sound, the field of sound technology is definitely making noise. In the past, sound engineers worked in the back rooms of recording studios, but many of today’s sound professionals are sharing their knowledge and experience with professionals in other fields to create new products based on the phenomenon we call sound.
Sound can be used as a weapon. Imagine that a police officer is chasing a thief. The thief tries to escape. And the officer can’t let him get away. He pulls out a special device, points it at the suspect, and switches it on. The thief drops to the ground. This new weapon is called a Long Range Acoustic Device (LRAD, 远程定向声波发射器). It produces a deafening sound so painful that it temporarily disables a person. The noise from the LRAD is directed like a ray of light and travels only into the ears of that person, but it is not deadly.
For those who hunger for some peace and quiet, sound can now create silence. Let’s say you are at the airport, and the little boy on the seat next to you is humming (哼唱) a short commercial song. He hums it over and over again, and you are about to go crazy. Thanks to the Silence Machine, a British invention, you can get rid of the sound without upsetting the boy or his parents. One may wonder how the Silence Machine works. Well, it functions by analyzing the waves of the incoming sound and creating a second set of outgoing waves. The two sets of waves cancel each other out. Simply turn the machine or point it at the target, and your peace and quiet comes back.
Directed sound is a new technology that allows companies to use sound in much the same way spotlights (聚光灯) are used in the theater. A spotlight lights up only one section of a stage; similarly, “spotsound” creates a circle of sound in on targeted area. This can be useful for businesses such as restaurants and stores because it offers a new way to attract customers. Restaurants can offer a choice of music along with the various food choices on the menu, allowing customers more control over the atmosphere in which they are dining. Directed sound is also beginning to appear in shopping centers and even at homes.

“Oh, no!” Jack shouted while looking at the likes and comments on his recent TikTok video.
“Why aren’t people reacting to my content as they used to?”
Jack was a 19-year-old strong and muscular man addicted to the gym. He loved recording exercise videos and posting them on his TikTok account. Initially, his video logs (vlogs) were popular, but his posts’ reach soon decreased.
Jack wondered why people had stopped sharing and liking his videos, “Maybe my audience is tired of watching me work out in the gym,” he thought, determined to change the location of his videos.
The following day, Jack went to the neighborhood park and began filming while walking on the track.“Hi, guys! How about we shake things up a little? I’m to work out in the park today!” he said excitedly, looking into the camera lens (镜头).
“Let’s look for a good spot to warm up,” he said as he walked towards a bench(长椅), on which sat an elderly lady. Jack thought the bench was the perfect place to film his video because of the light.
He put his tripod stand (三脚架) on the bench and set the camera, but he felt like he needed the full bench. He wanted to place his camera where the lady sat, so he gestured to her to move, but the woman didn’t seem to understand.
“Get out of my way!” he yelled.“Can’t you see I’m filming a video? You old fool!” Looking him up and down in surprise, the old lady didn’t argue over his disrespectful attitude and quietly walked towards another bench.
Jack set his camera up, pressed the record button and waved at his followers, ready to demonstrate exercises. Suddenly, he tripped on a loose stone, lost balance and fell down, his head striking the bench and bleeding heavily.
Crying in pain, Jack tried to get up, but he didn’t have the strength to rise. He collapsed on the ground, screaming desperately for help.

7 . The honeybee waggle dance has been celebrated as a most complex animal communication system. A study uncovered its new property that bees must partially learn the dance from watching experienced dancers, a discovery that torpedoes the general perception that the dance is wholly inborn. A dancer bee relays information to follower bees about the target location by adjusting herself while shaking her stomach, allowing for impressive flexibility in the angle, duration and her enthusiasm. Her body’s angle corresponds to the sun’s position relative to the nest entrance.
The distance information is conveyed by the dance duration. And the more energetic and passionate the dance, the better the food. She’ll waggle in a straight line for seconds before circling back to repeat the dance, creating the figure eight pattern.
This bee waggle dance system was long assumed to be natural behavior, but researchers made a breakthrough through an experiment. They created territories of newborn bees completely separated from mature ones. When the newborn started visiting flowers and producing their first waggle dances, they consistently made more errors in the way they reported the angle and distance to the food source than bees raised in mixed-aged territories and thus exposed to the waggle dance since they were born. They also generated looser figure eight patterns, making it harder for the follower bees to get the message. Even when placed back into a territory with mature bees, they never seemed to learn how to communicate information correctly.
These results suggest every honeybee is born with a waggle dance model that gives them a basic understanding of how to dance. By watching their elders, they’ll acquire new rules on how to generate the dance unique to their territory.
This is the first known example of such complex social learning of communication in insects and is a form of animal culture, strikingly similar to the way human language generates new languages to shape itself around the local conditions. While the waggle dance is second to human language in terms of the ability to communicate diverse information through random symbols, the newly-discovered property makes it even more language-like and just that much more mind-blowing.

8 . A school science project by a group of students in Canada has led to an important discovery: EpiPens might cease to function normally in space.
EpiPens, the auto-injectors (注射器) that deliver life-saving medicine called epinephrine, help with severe allergic(过敏) reactions. The epinephrine opens up airways, maintains heat function and blood pressure and calms the allergic reaction so the person can breathe.
The students working on Program for Gifted Learners (PGL), were curious about how radiation in space would affect the molecular (分子) structure of epinephrine. As part of a NASA initiative called “Cubes in Space,” which launches science experiments students come up with, they sent two cubes with samples of both pure epinephrine and EpiPen solution into space, one on a rocket and the other on a balloon. With the cubes too small to hold an entire EpiPen the students had consulted with Paul Mayer, a chemist at University of Ottawa and eventually figured out a way to get the EpiPen solution into a specially-made bottle.
The samples were analyzed in a lab before and after returning to Earth. The team found the pure epinephrine samples only returned 87 percent pure — the other 13 percent had turned into poisonous chemicals. And no epinephrine was found in the EpiPen solution samples.
Mayer was skeptical at first that the samples would show any signs of decomposition, but he was blown away by the “dramatic” results. “It’s brilliant,” he tells Global News. “The first part of doing science is asking the right questions, and they asked a fantastic question.”
The students’ findings could have real-world implications for space travel and astronauts’ safety. Excited to have made such a groundbreaking discovery, the students plan to do the experiment again to check their results. They’re also working on designing a capsule to protect the EpiPen solution in space.
“You feel like you’re making a real change,” says student Benjamin Sum, who wants to build rockets when he grows up. “It feels like it’s just adults. But kids can actually be involved.”

9 . “I know when to go out, and when to stay in.”, English rock star David Bowie once confidently sang in his hit single. When it comes to consuming food, the decisiveness claimed by the singer-songwriter is hard to achieve. I disagree with the statement and argue it’s better to eat out than to order home delivery.
To begin with, when setting foot in a restaurant, we’re immediately greeted not only by a server ready to seat us, but by a flood of physical feelings—the eyes take in the internal decoration of the place, the nose breathes in the pleasant smell of expertly plated food and the ears pick up on competing sounds of customer chatter and attractive in-store music. To eat out is to experience an atmosphere unique to each restaurant. Something as special as that simply can’t be reproduced by ordering home delivery. Eating out is, without doubt, the more exciting and thus better choice.
Eating out becomes even more appealing when staying home proves too painful. Whether it is because we need a temporary fight from our family or that we simply want to spend some quality time outside with loved ones, going out for a meal can be a break from the hard labour of domestic living.
We could take it as an opportunity for self-care—to treat ourselves by dressing up, arriving in style at a fancy restaurant and ordering a slightly more luxurious meal to refresh our weary soul. Ordering home delivery would only contribute to feelings of being penned in while; eating out is an escape for the trapped individual. Food delivery app users reason it’s a trouble and less convenient to dress up and eat out.
However, it’s worth noting we may not always get our food in the most satisfactory condition when opting for home delivery. There’s a risk of receiving food orders with missing items or even entirely wrong orders that can’t be sent back. What we sacrifice for convenience might just wind up being inconvenient. Consequently, it makes more sense to eat out rather than risk disappointment by ordering home delivery.
