2 . As reported in the journal Nature, one system can directly remove carbon dioxide from sources ranging from flue gas (烟道气) to the atmosphere by using electricity to induce a water-and-oxygen-based electrochemical reaction. This technological achievement could turn direct air capture (捕获) from edge industry into a promising front for climate change relief.
Most carbon-capture systems involve a two-step process: First, high-pH liquids are used to separate the carbon dioxide, which is acidic, from mixed-gas streams such as flue gas. Next, the carbon dioxide is regenerated from the solution through heating or by injecting a low-pH liquid.
“Once the carbon dioxide is trapped in these solvents (溶剂), you have to regenerate it,” says Haotian Wang, assistant professor at Rice University. “There are literally no chemicals produced or consumed with our process. We also don’t need to heat up or pressurize our device, we just need to put it into a power outlet and it will work.”
Another drawback of current carbon-capture technologies is their reliance on large-scale, centralized infrastructure. By contrast, the system developed in the Wang lab is an extensible, modular, point-of-use concept that can adapt to a variety of scenarios. “The technology can be scaled up to industrial settings-power plants, chemical plants-but the great thing about it is that it allows for small-scale use as well: I can even use it in my office.” Wang says.
Also the reactor can continuously remove carbon dioxide from a simulated (模拟的) flue gas with efficiency above 98% using a relatively low electricity input. Wang notes that the process has “no carbon footprint or a very limited footprint” if powered by electricity from renewable sources such as solar or wind. “This is great news considering that renewablel electricity is becoming more and more cost-effective,” Wang says.

3 . Around 3,500 Americans ingest (摄入) batteries every year. It’s apparently such a repeating issue that even a specific hotline was built in the event of such an emergency.
And while it’s unlikely your wristwatch’s power source will ever be safe to eat, that doesn’t mean all batteries will remain uneatable-in fact, some are being designed with digestion specifically in mind.
A team of researchers at the Italian Institute of Technology recently revealed what isl being called as the world’s first fully rechargeable, eatable battery. As detailed in a paper published with Advanced Materials, the new device has made good use of some eatable materials.
“Eatable electronic devices will have major implications for gastrointestinal tract (胃肠道) monitoring, treatment, as well as rapid food quality monitoring,” reads the paper’s abstract, adding that although recent research proved the feasibility of eatable sensors and circuits, “fully eatable electronic devices and eatable power sources are still required, of which there have been very few examples.”
According to the team’s findings, their proof-of-concept battery was capable of producing 0.65 volts, which is safely low enough for the human body to handle. The ingestible could provide 48 μA of current for 12 minutes, or alternatively, a few microamps (微安) for over an hour. Such a power supply could provide enough energy for small electronics alike to eatable pill-shaped modules and other gastrointestinal procedure alternatives.
In a statement, researcher coordinator Mario Caironi explained that such a product could help power monitors for both human health conditions and food storage. Additionally, given their safety, products with stronger power could be used within children’s toys, where ingestion risk is higher.
In the team’s statement, co-author Ivan Ilic also explained that despite the battery’s relatively low power, its digestibility provides a promising example of a battery that doesn’t use any harmful materials.

My dance school has a float in our town’s parade (游行) every year. I was so exciting when I got been selected to be part of the special dance. The rehearsals (排练) did conflict to a few of my soccer games. However, their teacher said it’d be okay as soon as I practised the steps at home. Well, I should have practised hardly! We were right in middle of the routine, and I turned right while the rest of the class went left. My mess-up caused a whole row of dancer to knock over. I heard the whole town went silent as they watched!

7 . Back in the day when I wasn’t sure what I wanted to do with my life, I liked to help others, so I was studying to become a firefighter. My parents always encouraged me at that time. As a firefighter, you’re constantly thinking of other people and trying to help them. It’s the mindset. which is the most difficult part in this job!
One night I was heading home and decided to stop off at a burrito (玉米饼) place. I was approached by a homeless man. He was very dirty and obviously hungry. He asked me for some change to buy a little food. As I was pulling some change out, I had an idea.
I decided to see if he wanted to eat a real dinner, so I asked him to follow me back into the Burrito Joint to order. When he followed me in, the people behind the counter refused to let him in. After some arguing, so I had to encourage him to order whatever and however much he wanted. He ended up ordering enough to fill his stomach at least 3 times over!
For someone who has been on the edges of society it seemed like he was very surprised at my kind behaviour. But to me, it was what any “human being” should do or at least offer. I know we see these people every day asking for money but you had to be there to see the look in his face. To me, it reminded me when I was young and my mum brought out a big birthday cake for me on my birthday, with all the candy, getting to experience a big meal. And I think he felt special, like he was getting attention. Again something that I could see he hadn’t experienced in a long time.
I often think about this story, because to me it’s not just about helping someone out by feeding them, but giving him the respect of being a human being and allowing him to feel good about himself was very rewarding.

8 . We humans love to stare into our smart devices. We gaze for hours—about 10 hours and 39 minutes a day—at our computers, smartphones, tablets and televisions. Is all this staring bad for us? It might be, mainly because as we stare at our devices we are exposing ourselves to blue light.
Blue light is a type of electromagnetic radiation with a very short wavelength that produces a high amount of energy. While it’s true that light can damage our eyes under certain circumstances, there’s no scientific evidence suggesting that blue light is harmful to our eyes. But many people still think it is, which is why blue-light-blocking glasses are so popular. So, do the glasses work?
“Everyone is very concerned that blue light may be causing damage to the eye, but there’s no evidence that it may be causing serious damage, ” Dr. Rahul Khurana, a clinical spokesman, told Business Insider.
Blue light exposure is nothing new. In fact, the sun is the largest source of blue light. Moreover, blue light is also present in LED light. But if blue light isn’t harmful, then why are we constantly rubbing our eyes when we’re looking at our screens? The answer is eyestrain (眼疲劳). More than 60 percent of people experience eye problems associated with digital eyestrain. And blue light, it seems isn’t the cause. Instead, our eyes are so strained because most of us blink less when we stare at our digital devices. So, if eyestrain is the real issue, blue-light-blocking glasses are probably of little use.

9 . It was a rainy day. I had no desire to drive up the winding mountain road to my daughter Carolyn's house. But she had insisted that I come to see something at the top of the mountain.
So here I was, although unwilling to make the two-hour journey through fog and rain. After lunch, my daughter requested me to drive her to Barage. After a ten-minute drive, we parked the car and got out. We walked along a path that was thick with old pine needles. Huge black green evergreens towered over us. Gradually the peace and silence of the place began to fill my mind. Then we turned a comer and stopped--and I gasped in amazement.
From the top of the mountain to the slopes and valleys, were rivers of daffodils(水仙) in full bloom. A sea of amazing colors, like a carpet before us. It looked as though the sun had tipped over and spilled gold down the mountainside. At the center hung a waterfall of purple hyacinths. Here and there were breathtaking tulips(郁金香).
A lot of questions filled my mind. Who created such beauty? Why? How?
As we approached the home that stood in the center of the property, we saw a sign that read, "Answers to the Questions I Know You Are Asking". The first answer was:"One Woman--Two Hands, Two Feet, and Very Little Brain." The second was: "One at a Time." The third: "Started in 1958."
I was so moved by what we had seen. "She changed the world," I said, not getting over the shock, "one bulb (球茎) at a time. She started almost 40 years ago, probably just the beginning of an idea, but she kept at it."
"Imagine," I added, "if I had a vision and worked at it, just a little bit every day, what might I have accomplished?"
Carolyn looked sideways at me, smiling. "Start tomorrow," she said. "Better yet, start today."
