My high school life has been filled with many ups and downs, whether it was social or academic. Even though my current high school was not my first choice, I never regretted attending Southside High School. “Since you have chosen it, then it is the best for you,” said my parents.

    Up until the junior year I did not realize my capabilities (能力) as a student. Being in the IB Program, I was told that my junior year would be the toughest in all the years of high school. With this “little” piece of information, I walked into my junior year, scared of my grades. As weeks went by, I started to believe that the junior year was not as hard as everyone had said, but I was wrong. My grades were rapidly declining(下降) and by the end of the first term I had five Cs in seven of my classes! I could not believe it — I did not want to believe it. I tried my best to get my grades up myself without any help from anyone, but my pride just made my grades worse. And I had to miss out on one of the most important speech and debate competitions all year: States. I was heartbroken. I realized that I could not survive my junior year on my own, so I had to get help fast.

    Once I got a tutor, my grades went from Cs, Ds, and even some Fs, to nothing but As and Bs. I slowly started to gain my confidence back in all of my classes and even myself. By the time the third and fourth quarter came around, I had been on the honor roll twice, and I was receiving awards from speeches and debates, tennis and school.

    Southside has taught me to always keep my head up and never give up on myself no matter what life throws at me. I am proud to be a Southside Tiger.

    Most people agree that eating healthy food is important. But sometimes making good food choices can be difficult. Now, there are apps that can help people learn about the food they eat to improve their health and their dining out experience.

    Happy Cow app

    Vegetarians do not eat animal meat. Vegans do not eat any animal products. The HappyCow app is made for both groups. Users can search for vegetarian-vegan restaurants and stores around the world.

    Open Table app

    Open Table app helps people choose restaurants when they want to go out to eat. It is a free service that shows users restaurant available based on where and when they want to dine. It gives users points when they make reservations(保留，预定), which can add up to discounts on restaurant visits.

    Local Eats app

    Restaurant chains, like McDonalds, can be found almost anywhere a person might travel. But sometimes travelers want to eat like locals. The Local Eats app is designed for that. It can help you find local restaurants in major cities in the US and in other countries. It costs about a dollar.

Where Chefs Eat app

    "Where Chefs Eat" is a 975-page book. Most people would not want to carry that around. But there is a much lighter app version of the same name for just $15. Six hundred chefs provide information on 3,000 restaurants around the world on the Where Chefs Eat app.

    Do you still use a power button(开机键)to open your smart phones or computers? You are out of fashion! Now most smart phones are using facial-recognition system(面部识别系统), and we already have machines that can know you from your fingers and your voice too. But some companies are still willing to invent other systems to "break" these systems, for example, the eye-recognition system. As is reported, you'll just have to look at the computers and machines, and this system will be able to tell you who you are by looking at your eyes, even when you are wearing glasses.

    Do you wonder if this system will work well? The answer is YES. All you need is just look at your machines. The eye scanner(扫描仪)is put in the cameras of your machines. The eye-recognition system is safer and easier than other systems. This is because everyone's eyes are different. Since the system works easily, you won't have to remember a group of code when you want to open your computer or take money out of a bank in the future. Eye-recognition system is better than other kinds of systems because your eyes don't change as you get older, and don't get dirty like hands or fingers. Even twins' eyes are not the same. So the eye-recognition system can be up to 94 percent correct, but it depends on how good the technology is. Some systems may only 51% right. In Britain, it was found that 91 percent of the people who had tried it said that they liked the idea of eye-recognition. So scientists think it will become more popular than other systems.

    The eye-recognition system has already been tested in shops in the USA, Britain, Spain, Italy and Turkey Soon it will become a popular way among public. In the future, your computer will be opened by looking at your eyes.

When I first heard about the improv(即兴表演) classes, I was torn. As an introvert, I feared getting on stage and improvising in front of strangers. However, I knew I wanted to work as a science communicator after finishing my Ph.D. , so it seemed like the perfect opportunity to improve my speaking ability and gain confidence thinking on my feet.

During our first class, we learned a core concept of improv: "yes, and." It means that, as improvisers, we accept what fellow performers say. If someone says that rhinos(犀牛) are librarians, for example, then rhinos are librarians. We do not question the logic; we say "yes" and continue with the scene as if no him is wrong.

I got a taste of how difficult that was when acting out my first scene. My classmate turned to me and said, "Mom is going to be so mad." Mad about what? My mind spun out ideas, and my inner critic shot them all down. We broke the car? No, that's too easy. We failed a test? No, you don't want your classmates thinking you're stupid on the first day. I finally landed on an answer: "Yes, we're going to be late for dinner." The scene proceeded from there, and we eventually finished as two sisters who lost their way on a hiking trail.

The first few scenes were hard, but as weeks turned into months, I became more comfortable thinking on my feet and even started to enjoy our classes. I never silenced my inner critic entirely, but over time, I didn't police my words with quite so much effort. I also became better at listening, relating to my conversation partners, and communicating clearly in the moment.

That training proved useful 6 months ago, when my experiments generated unreasonable data. Early on in graduate school, I would get stuck when this happened; my inner critic would assume I had made a mistake. But then, after embracing the "yes, and" concept, instead of getting discouraged, I kept exploring the data and ended up identifying a new type of cell—one that wasn't behaving as expected. If I hadn't accepted the possibility that the results were real, I would have missed out on the most exciting finding of my Ph.D. so far.

All scientists can benefit from this lesson. If the data say rhinos are librarians, then it's worth investigating whether rhinos are, in fact, librarians. Our job as scientists isn't to generate data that support a preconceived(预想的) story. Our job is to say "yes, and."
