Chasing a Dream
I will never forget that November day. It was hotter than normal — too hot. My throat felt like a field of cotton, cracked with the summer heat, as I waited for the gun to fire. This was the day we had waited so long for. I looked out at the crowd; dozens of familiar faces flashed across my view. They had come for me. They were counting on me. I saw my dad set his watch, with worry and excitement on his face. Adrenaline (肾上腺素) pumped through my body, and the race began.
For the first two and a half miles, I felt great. I had never before been so ready for something. The weeks leading up to the race were filled with strictly controlled practices and a strict diet. My friends hadn’t seen me in weeks, but they understood the sacrifice required to make my dream a reality.
My dad and I had been working towards this race for three years. It was everything to me, and it was everything to my dad. He was a runner and was excited by my success in running. He made it to every race, even flying home early from business trips to see me run. I always listened for his voice — telling me to relax my arms, calling out my time. He pushed me. He cheered for me. He believed in me. We spent countless hours on the sandy canals. Breathing in the dust of the desert, the blossoms (花簇) of the orange trees, we made our way across the city. We pounded miles and miles into our running shoes, marking with every step the path to greatness.
But without warning, when I was 200 yards away from the finish line, my legs stopped working. My lungs fought to take in enough air, and my feet transformed into cement (水泥) bricks. I still don’t know what happened in those last few moments. Nothing I could do would make them hold my weight. They were as weak as jelly.

People tend to cut corners and allow trusted workmates to do their work when working as a team. Now researchers have found that the same thing happens when humans work with robots.
Dietlind Cymek at the Technical University of Berlin in Germany and her colleagues designed an experiment to test whether humans would put in less effort when they think that their personal contribution to a task won’t be noticed.
In the experiment, the researchers asked a group of 42 people to examine images of circuit boards (电路板) for errors using a computer that tracked their work. Half of them looked at boards that had already been checked by a robot, and half were told that they were the only ones responsible for quality control.
People working in partnership with the robot caught fewer errors, after they had already seen that the robot had successfully flagged lots of errors.
The researchers say such teamwork could lead to a drop in motivation if individual effort isn’t visible and warn that there could be safety risks if teams of people and robots work on safety-related tasks in the same way.
Kathleen Richardson at De Montfort University in Leicester, UK, says it is fine to use robots as long as they are effective, but that they should be considered tools rather than workmates or team members. “It just strikes me that workers think when a tool can do something, they let it,” says Richardson.
This is probably down to poor management style, in which individual work isn’t recognised. “I bet you if there was an motivation behind it, and if the humans could get extra pay for spotting errors in the circuit boards, then they’d put a bit more effort into it,” she adds.

9 . Most glitter(小发光物品), which is made up of tiny pieces of plastic, is a huge danger to the environment. “Everyone talks about the mountain of plastic floating in the ocean. You can grab empty bottles from the water, but with tiny pieces, it’s impossible,” says Victor Alvarez, a chemical engineer who sells an eco-friendly alternative to glitter.
In the early 2,000s, Alvarez worked for Mercedes-Benz in Germany, where he became fond of any technology that protected the environment. A few years after leaving Mercedes-Benz, he founded Blue Sun International in Miami, which makes specialty ingredients for the skin and hair care industries.
Glitter is a popular ingredient in cosmetics, such as eye shadows and lipsticks. So Alvarez began researching an alternative that didn’t contain plastic to make his products safer for the environment. That’s when he came across Ronald Britton Ltd., a company which had developed a plastic-free, biodegradable product called Bioglitter. It is made from regenerative cellulose(纤维素) sourced from hardwoods, primarily eucalyptus(桉树). Alvarez worked with the company to become the first retailer to sell Bioglitter in America. In 2018, he formed Today Glitter in order to sell the biodegradable glitter directly to consumers through its website.
Today Glitter sells two kinds of biodegradable glitter Bioglitter Sparkle and Bioglitter Pure. Both are almost plastic-free and can biodegrade in a short time. Meanwhile, they are as shiny as regular glitter. All these products are third-party tested by TÜV, an international organization that provides testing and certification for compostable (可降解的) and biodegradable products.
Despite its benefits, the hardwoods needed to make biodegradable glitter cause it to cost about twice as much as conventional glitter. A small glass container that contains just 6 grams of Bioglitter costs $10, while the same amount of regular glitter could cost at least half that amount. Alvarez expects the price will come down over time. He also expects the company’s sales to cross $1 million next year. But more importantly, Alvarez says, his main goal is to effect a meaningful change.

10 . Birds rely on their keen sense of hearing to detect prey (猎物) and identify other birds on the basis of their songs. In fact, birds have better hearing than humans, so they hear with much more detail. So how do birds hear?
Birds and humans both have an inner ear and a middle ear. However, birds differ from humans in that they lack an external ear structure. Where humans have an outer ear organ, birds have a funnel-shaped opening that functions as their outer ear, located on each side of their head. These openings are usually positioned behind and slightly below a bird’s eyes and are protected by soft feathers.
The position of a bird’s head also plays a role in its hearing abilities. Scientists have determined that noises register at different frequencies on each side of the bird’s head. Depending on the angle from which the noise originates, it registers with a certain frequency in the left eardrum but with a different frequency in the right eardrum. This allows the bird to locate a sound’s origin.
For example, owls are known for their extremely accurate hearing, which helps them locate prey at night. This hearing ability is due in part to the unbalanced arrangement of the ear openings, with one opening being lower than the other. Sounds register in these openings at slightly different times. Owls can use this time difference, which is only 30 millionths of a second, to determine whether the sounds are coming from their left or their right. Other birds of prey have flaps in front of their ears that help them determine whether sounds are coming from above them or below them. Some owls do appear to have ears on the top of their head, but those are actually feathers controlled by small muscles under the skin that do not affect their hearing at all.
