Looking at her worn-out sneakers (运动鞋), Sarah felt embarrassed (尴尬的)going to school wearing them.
“What’s the matter, Sarah? Is there something wrong with the food?” her mother asked.
Sarah, in a high voice, shouted, “I am sick of these shoes! I am no longer wearing these to my school! Do you know how embarrassing it is?”
Meghan, (Sarah’s mother) was a single mother working in a nearby town cafe. She explained, “Right now, we’re on a tight budget(预算很紧). I’ll make sure to get you a new pair next month.”
Sarah picked up her schoolbag and walked to school, giving her mother a dissatisfied look.
The school was going to organize a sports competition and Sarah was filled out the form for a 100-meter race.
When one of her friends saw this, she asked Sarah if she was certain about running the race. Sarah didn’t understand what her friend meant.
”Dear, if you have a new pair of shoes, then it’s fine. But if you choose to wear the ones you are wearing now, I’m afraid you will lose the race!“ the friend said, pointing at Sarah’s shoes. Sarah simply nodded and returned to her classroom without saying anything.
Later that day, on her way home, Sarah realized she hadn’t eaten her lunch, so she stopped at a bus stop to finish it.
When she began eating, she noticed that a child was standing next to her in poor clothes. Sarah knew the kid needed that sandwich that she was eating since the kid stared at her and then at her food.
Sarah handed the sandwich to the child, who ran up to her, excitedly got the sandwich from Sarah’s hand and began eating it. After finishing the sandwich, the child thanked Sarah, saying, ”I haven’t had such a tasty sandwich in a long time. My father is a cleaner in a house down the street and my mother is a patient at a hospital. Oh, and my name is Sam.”

2 . Restricting meals to early in the day did not affect weight among overweight adults with prediabetes or diabetes(糖尿病), according to a research presented at the American Heart Association's Scientific Sessions 2020.
“We have wondered for a long time if when one eats during the day affects the way the body uses and stores energy,” said study author Nisa M. Maruthur, associate professor of medicine in Johns Hopkins University in Baltimore. “Most previous studies have not controlled the number of calories, so it wasn't clear if people who ate earlier just ate fewer calories. In this study, the only thing we changed was the time of eating in the day.”
Maruthur and colleagues followed 41 overweight adults in a 12-week study. Most participants(参与者)（90%）were African American women with prediabetes or diabetes, and average age of 59 years. Twenty-one of the adults followed a time-restricted eating pattern, limiting eating to specific hours of the day and ate 80% of their calories before 1 pm. The remaining 20 participants ate at usual times during a 12-hour window, consuming half of their daily calories after 5 pm for the entire 12 weeks. All participants consumed the same pre-prepared, healthy meals provided for the study. Weight and blood pressure were measured at the beginning of the study；then at 4 weeks, 8 weeks and 12 weeks.
The analysis found that people in both groups lost weight and had decreased blood pressure no matter when they ate. "We thought that the time-restricted group would lose more weight,” Maruthur said. “Yet that didn't happen. We did not see any difference in weight loss for those who ate most of their calories earlier versus later in the day. We did not see any effects on blood pressure either.”
The researchers are now collecting more detailed information on blood pressure recorded over 24 hours, and they will bring this information together with the results of a study on the effects of time-restricted feeding on blood sugar, insulin(胰岛素)and other hormones and making analyses on the data. "Together, these findings will help us to more fully understand the effects of time-restricted eating on cardiometabolic(心血管代谢)health," Maruthur said.

4 . At most universities, core (核心) curriculum or general education is required, whether that is two or more courses in core academic subjects. These core academics consist of mathematics, science, history and English, which are used to provide students with a broad range of academic knowledge and aid in their individual development.
However, are these courses more beneficial or harmful to students? Based on studies from across the district there is a gap between the necessities and burdens of general education courses. According to an article by Best Value Schools, students sometimes discover a hidden passion for a field of study while taking general education courses. Although this may be true, many students consider the program as “a collection of courses without connection, consistency or meaning”. The negative concept of these courses could possibly be connected to the fact that many students don’t actually obtain these skills.
Many schools have been working to improve their core curriculum program by developing the adoption of mission, goal and outcome statements. Some University of North Carolina at Greensboro (UNCG) professors have recently been requiring students to take self-assessments and complete assignments based on how to develop critical thinking, communication and cooperation skills, as well as apply them within and outside of the classroom. It is through these channels of self discovery that students can often find their passions, which can possibly lead to choosing a major.
Typically, one-third of first-time college students change their major within the first three years. Major changes can be for a variety of reasons. It can be associated with a dissatisfaction in coursework. It can also be due to the discovery of a major which simply fits a student better. General education classes can play an important role in helping to make this discovery. Though students’ opinions vary on the importance of core curriculum, the basis of the program should be taken into consideration. At the same time, institutions should continue to work towards developing more authentic ways to provide a sense of importance and pride in the program to aid in student learning and the development of real-world skills.

5 . A simple blood test that can tell how well a person is likely to age is on the horizon after scientists uncovered blood signature patterns which predict ill health. The breakthrough means doctors will soon be able to check the likelihood of dementia(痴呆), cardiovascular disease and a range of other conditions many years before patients show any symptoms.
Researchers at Boston University learned to recognize combinations of specific biomarkers (生物标志物), or chemicals found in the blood, of 5,000 people in a study. They then matched these with the participants’ health outcomes over a period of eight years. They found specific patterns associated with disease and disability-free aging, as well as patterns associated with the threat of several diseases.
While various techniques already exist for predicting specific conditions, such as heart disease, the new approach will, for the most part, enable doctors to paint a comprehensive picture of their patient’s overall future health. It also promises to give people the chance to change their lifestyles or begin preventative treatment to circumvent diseases considered as a risk by their blood composition.
“These signatures show differences in how people age, and they show promise in predicting healthy ageing, changes in cognitive(认知的) and physical function, survival and age-related diseases like stroke, type 2 diabetes and cancer,” the research team said. “We can now measure thousands of biomarkers from a small amount of blood with the idea of eventually being able to predict who is at risk of a wide range of diseases long before any clinical signs become apparent.”

8 . An experimental cleanup device called RemoveDebris has successfully cast a net around adummy (仿造的) satellite, simulating (模拟) a technique that could one day collect spaceborne garbage.
The test, which was carried out this week, is widely believed to be the first successful demonstration of space cleanup technology, experts told CNN. And it signals an early step toward dealing with what is already a key problem: rubbish in space.
Millions of pieces of junk are turning around in orbit, the result of 50 years of space travel and few regulations to keep space clean. At orbital speeds, even a small bit of paint crashing with a satellite can cause serious damage.
Various companies have plans to send thousands of new satellites into low-Earth orbit, already the most crowded area.
The RemoveDebris experiment is run by a company and researchers led by the UK’s Surrey Space Centre and includes Airbus, Airbus-owned Surrey Satellite Technology Ltd. and France’s Ariane Group.
Guglielmo Aglietti, the director of Surrey Space Centre, said that an operational version of the RemoveDebris technology would cast out a net that remains fastened to the main satellite so the debris can be dragged out of orbit. It could target large pieces of junk, including dead satellites up to 10meters long.
The RemoveDebris satellite will conduct a few more experiments in the coming months, including testing navigation systems that could help guide the satellite to a specific piece of debris. Jonathan McDowell, an astrophysicist at the Harvard Smithsonian Centre for Astrophysics, said the success of this week’s experiment was exciting, but he cautioned against “over-publicizing” it. There are still big barriers to clear before operational cleanup tasks will be underway, he said, and the biggest challenge is figuring out how to fund such projects.
Aglietti, the Surrey professor who helped lead the RemoveDebris project, said “the challenge will be to convince the relevant authorities to sponsor these tasks”. Aglietti said he hopes RemoveDebris will conduct a few cleanup tasks per year, targeting the largest pieces of rubbish in the most crowded orbits. Aglietti is hopeful.

10 . Some people are early risers while others can’t seem to get to bed until well after midnight. Why is this? A research team has a new finding that shows how a “switch” in the biological clocks of early risers leads them to operate on a daily cycle of about 20 hours instead of a full 24-hour cycle.
This finding from Carrie Partch and her colleagues builds on decades of research into biological clocks, which control sleeping and waking, rest and activity, body temperature, heart rate and so on.
Partch and her colleagues focus on two main clock components: an enzyme (酶) known as casein kinase 1 (CK1) and a protein (蛋白质) called PERIOD. It turns out that the timing of biological clocks is strongly influenced by the rise and fall of the PERIOD protein, and this daily change normally takes place over 24 hours. But CK1 adjusts PERIOD levels by chemically modifying the protein, thereby adjusting its stability.
What they’ve discovered is that a part of CK1 acts as a switch. When this switch functions normally, it generates a near- perfect 24-hour cycle by keeping PERIOD’s stability right. In this case, people easily and correctly match their biological clocks with the daily coming and going of daylight.
If the switch favors a faster breakdown of the protein, the daily cycle grows shorter and less tightly bound to daylight. For these early risers, it’s a constant struggle to adjust to life in a 24-hour world. On the contrary, a switch that favors a slower breakdown will lengthen the clock, causing some people to be night owls (夜猫子).
Partch’s discoveries are sure to offer a new view on how the biological clocks make us tick. She hopes they’ll result in new ways to adjust the clocks in people with sleep disorders and even the means to reset the clocks in people who regularly travel overseas or work the night shift.
