2 . On Saturday, Jacob Kohut finally had breaktime during his 12⁃hour standing guard outside the U.S. Capitol. He could have spent his break resting. Instead, he sat in the back of a Humvee, teaching students via his laptop how to play Beethoven’s “Ode to Joy”, which meant he was on double duty, as an active member of the National Guard and as a devoted school band teacher.
“I’m a soldier for the National Guard, but I’m as much a solider for music education,” he says.
When on duty, Kohut’s days began in the morning with teaching his elementary class remotely from the drill floor of DC Armory, finishing the lesson minutes before his Guard shift started at 10 a.m. Later in the day, during his break, he would go online to teach his middle school students from the back of a Humvee.
Music has always been a driving force in Kohut’s life. He was a saxophone player throughout high school, and finally earned his Doctor degree in music composition at George Mason University.
“What I really wanted was to teach,” says Kohut, who is married and has a three⁃year⁃old son. “My mom, who is a single mother, was a music teacher. That’s why I do what I do. She is such a good role model.”
Kohut’s double duty has caught the attention of parents at Canterbury Woods Elementary School.
“I just wanted to share how impressed I am with Dr. Kohut this week,” Susi Britain said. “This morning he taught the band online from DC Armory, in his tiredness — which just seems so beyond the expectations of a teacher in these circumstances.”
But during the long and sometimes stressful hours of standing guard, Kohut said his teaching time offered comfort. As the 11 instruments were played by his virtual students, the familiar melody of “Ode to Joy” rang through the Humvee. In that moment, Kohut realized there wasn’t a timelier tune to teach his students
“It’s a symbol of unity and peace,” he says. “And that’s what the world needs right now.”

4 . Close to the North Pole, the remote and rocky plateau mountain in the Norwegian archipelago of Svalbard seems an unlikely spot for any global effort to safeguard agriculture. In this cold and deserted environment, there are no grains, no gardens and no trees. But at the end of a 130⁃meter⁃long tunnel is a room filled with humanity’s most precious treasure, the largest and most diverse seed collection — more than a half⁃billion seeds.
A quiet rescue mission is underway. With growing evidence that unchecked climate change will seriously affect food production and threaten the diversity of crops around the world, the Svalbard Global Seed Vault represents a major step towards ensuring the preservation of hundreds of thousands of crop varieties. This is a seed collection, but more importantly, it is a collection of the traits (特点) found within the seeds: the genes that give one variety resistance to a particular pest and another variety tolerance for hot, dry weather.
Few people will ever see or come into contact with the contents of this vault. In sealed (密封的) boxes, behind many locked doors, monitored by electronic security systems, enveloped in below⁃zero temperatures, and surrounded by tons of rocks, hundreds of millions of seeds are protected in their mountain fortress (堡垒). Frozen in such conditions inside the mountain, seeds of most major crops will remain viable for hundreds of years, or longer. Seeds of some are capable of keeping their ability to grow for thousands of years.
Everyone can look back now and say that the Seed Vault has been a good and obvious idea, and that of course the Norwegian government should have approved and funded it. But back in 2004, when the Seed Vault was first proposed, it was viewed as a crazy, impractical, and expensive idea.
We knew that nothing would provide a definite guarantee. But we were tired and frankly scared of the steady, greater losses of crop diversity. The Seed Vault was built by optimists who wanted to do something to preserve options so that humanity and the crops might be better prepared for change.
The Seed Vault is about hope and commitment — about what can be done if countries come together and work cooperatively to accomplish something significant, long⁃lasting, and worthy of who we are and wish to be.

5 . Researchers at the University of Texas Southwestern Medical Center mapped brain changes after a year of aerobic workouts and uncovered a potentially significant process: Aerobic exercise increases blood flow into two key areas of the brain associated with memory.
The study, published in the Journal of Alzheimer’s Disease, showed this blood flow can help even older people with memory problems improve cognition, a finding that could guide future Alzheimer’s disease research, according to UT Southwestern Medical Center.
In the study, researchers followed 30 participants who were 60 or older and had memory problems. Half experienced a year of aerobic exercise while the other half did stretches. “We’ve shown that even when your memory starts to fade, you can still do something about it by adding aerobic exercise to your lifestyle,” said Binu Thomas, a senior research scientist of UT Southwestern Medical Center who led the study. “The aerobic exercise group showed a 47% improvement in some memory scores after a year; the other group showed slight change. Brain imaging of the aerobic exercise group, taken while at rest at the beginning and end of the study, showed increased blood flows into the specific brain areas that play important roles in memory function.”
Many teams across the world are trying to determine if aerobic exercise might fight memory loss. Evidence is growing that it could at least play a small role in delaying or reducing the risk of Alzheimer’s disease. For example, a 2018 study showed that people with lower fitness levels experience faster retrogression of vital nerve fibers in the brain called white matter related to memory.
“Blood flow in the brain connected with memory improvement is still a part of the puzzle, and we need to continue piecing it together,” Thomas says. “But we’ve seen enough data to know that starting a fitness program can have lifelong benefits for our brains as well as our hearts.”

In 1989, fresh from high school, I had the difficult task of choosing a career path before college started in three months. In those days in Pakistan, there were limited choices: becoming a doctor or an engineer, or entering the financial world after getting a business degree. I wasn’t interested in engineering, so that I was left with medicine or business. I couldn’t decide.
My uncle suggested that I do a work placement (实习工作) to experience it for a month in an international company followed by a month in a hospital. After that, I could make a decision. It seemed like a good idea.
I was accepted by a foreign bank in Karachi for a one⁃month placement. I got the feel of how the world of finance functioned, made new friends, and generally enjoyed the mostly easy⁃going work surroundings.
The month passed rapidly, and soon I began working at a leading hospital in Karachi. The experience couldn’t have been more different. The hospital had a stressful environment. The days started early (at 7 am, compared to 9 am at the bank), and were filled with endless duties. And the night calls! This was crazy, working all day, through the night, and again the next day.
I began thinking about my two experiences. The bank had offered a more relaxing atmosphere, better working hours and less stress. The hospital was full of excitement, but the studying and training were difficult. It seemed that the business choice was going to win out.
Near the end of my month at the hospital, I was driving home after an especially busy night. In front of me was a public bus, with college students sitting on the top. As the driver weaved through (穿梭) traffic, I could see the boys shaking from side to side.

9 . If you could change your children’s DNA in the future to protect them against diseases, would you? It could be possible because of technology known as CRISPR/Cas, or just CRISPR.
CRISPR involves a piece of RNA, a chemical messenger, designed to work on one part of DNA; it also uses an enzyme that can take unwanted genes out and put new ones in, according to The Economist. There are other ways of editing DNA, but CRISPR will do it very simply, quickly, and exactly.
The use of CRISPR could mean that cures are developed for everything from Alzheimer’s disease to cancer to AIDS. By allowing doctors to put just the right cancer⁃killing genes into a patient’s immune system, the technology could help greatly.
In April scientists in China said they had tried using CRISPR to edit the genomes (基因组) of human embryos. Though the embryos would never turn into humans, this was the first time anyone had ever tried to edit DNA from human beings. With this in mind, the US National Academy of Sciences plans to discuss questions about CRISPR’s ethics (伦理标准). For example, CRISPR doesn’t work properly yet. As well as cutting the DNA it is looking for, it often cuts other DNA, too. In addition, we currently seem to have too little understanding of what DNA gives people what qualities.
There are also moral questions. Of course, medicine already stops natural things from happening—for example, it saves people from infections. The opportunities to treat diseases make it hard to say we shouldn’t keep going.
A harder question is whether it is ever right to edit human cells and make changes that are passed on to children. This is banned in 40 countries and restricted in many others. However, CRISPR means that if genes can be edited out, they can also be edited back in. It may be up to us as a society to decide when and where editing the genome is wrong.
Also, according to The Economist, gene editing may mean that parents make choices that are not obviously in the best interests of their children: “Deaf parents may prefer their children to be deaf too; parents might want to make their children more intelligent at all costs.”
In the end, more research is still needed to see what we can and can’t do with CRISPR. “It’s still a huge mystery how we work,” Craig Mello, a UMass Chan Medical School biologist and Nobel Prize winner, told The Boston Globe. “We’re just trying to figure out this amazingly complicated thing we call life.”
