If you'll be taking vacation time in the coming year and plan on flying, here are some useful tips for buying a cheap ticket.

When to buy

If you're going to buy tickets for domestic (国内的) flights, check prices on Tuesday afternoons. This is an old tip but still useful because most U. S. carriers continue to release sales on Tuesday morning, and competitors quickly drop their fares to match the better deals.

When to fly

Weekdays continue to be generally cheaper times to fly than weekends for most flights. In the U. S. , the cheapest days are typically Tuesday, Wednesday and Saturday. A good itinerary (旅行计划) for the expensive U. S. spring break travel period is scheduled from Tuesday to Saturday; it will save you money (in most cases).

Where to fly

We continue to see good deals to Boston and Denver and more and more nice prices to Chicago, Seattle and Washington, D. C. . As for Europe, there have been surprising deals throughout the fall and those will continue into the winter.

Direct flights vs connecting flights

Compare the price of direct flights with that of connecting flights. Sometimes adding a stop to your route will save you money, and it might be enough to endure the extra long flying day. An example: San Francisco to Raleigh: $553 for a direct flight, $362 with one stop.

You'd better think twice about the direct flight for San Francisco to Raleigh.

Compare, compare, compare

Stifle the impulseto go to your favorite airline site to purchase tickets without doing any comparison. Example: Let's say you want to fly from New York to London and figure your favorite U. S. legacy carrier will get you there for the best price—$554 for a round trip.

However, the comparison site also shows a cheaper flight from the same legacy carrier ($521). See what you're missing when you fail to do comparison?

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 light­blocking 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, clinical spokesman for the American Academy of Ophthalmology, 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 lights. 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 light­blocking glasses are probably of little use.

Thanks to a program called Hunger: Not Impossible (HNI), hungry people could have access to fresh, healthy food in their neighborhood by texting one simple word: Hungry. On one hand. people in charge of the program learn that each year 42 million Americans go hungry including 15. 9 million children. On the other hand, grocery stores, restaurants, and food providers throw out 60 million tons of unused food. HNI had a solution—connectivity.

HNI started fundraising and developing partnerships. Then they make plans with organizations and charities to help locate people who suffer from food insecurity. And they reached out to technical experts at Salesforce who developed an easy-to-use text-driven platform using a chat box. With all the elements in place, a simple text started the goodwill rolling.

When a needy person types in "Hungry" and sends the text message to HNI. they receive a message, back showing the closest locations that are offering free food. They also get a text displaying different menu options. They simply select a restaurant, choose the meal, then heads to the takeout counter where they pick up their free meal alongside paying customers. No questions are asked and dignity is preserved. The pilot project began in Venice Beach, California, providing over 250 meals to more than 50 youth in three weeks. HNI then grew to Bentonville. Arkansas, Klamath Falls Oregon? and St; Louis. Missouri.

"Providing food is the first step in transforming lives for the best." Michelle DiBattiste, operations and volunteer manager at Safe Place for Youth said in the press release, "By satisfying that initial survived instinct of finding food. Hunger: Not Impossible provides necessary space for personal growth, self-realization and finding stability. If there were less hungry people in the world, the crime rate would be reduced? there would be fewer homeless people, and the cost of healthcare would cut down. "

Most of the wind available on land is too gentle to push commercial wind turbine(涡轮机), but now researchers in China have designed a kind of "tiny wind turbine^,, that can use wind energy from breezes as little as those created by a quick walk. The new device is not technically a turbine. It is a nanogenerator made of two plastic strips in a tube that clap together when there is airflow. Like rubbing a balloon to your hair, the two plastics become electrically charged after being separated from contact, a phenomenon called the triboelectric effect. But instead of making your hair stand up like Einstein's, the electricity generated by the two plastic strips is captured and stored.

"Our intention isn't to replace existing wind power generation technology. "Our goal is to solve the issues that the traditional wind turbines can't solve?" says Ya Yang, a researcher from Beijing Institute of Nanoenergy and Nanosystems. "Unlike wind turbines that use coils and magnets (磁石) where the costs are fixed, we can pick and choose low-cost materials for our device. Our device can also be safely applied to nature reserves or cities because it doesn't have the rotating (旋转) structures.

Yang says he has a small vision and a big vision for the project's next steps. In the past, Yang and his colleagues have designed a nanogenerator as small as a coin, but he wants to make it even tinier and more compact with higher efficiency. Yang is also looking to make the device bigger and more powerful. "I'm hoping to scale up the device to produce 1,000 watts. We can place these devices where traditional wind turbines can't reach. We can put it in the mountains or on the top of buildings for sustainable energy.

Sam and I had been paired up through a mentoring (辅导) program when he was a first grader. As a former teacher, I missed making an impact on young people, so as soon as I heard of this program for at-risk school kids, I signed up.

At first, if didn't seem as if the two of us were a good match. Sam hardly looked at me; he barely spoke or smiled. I tried everything to engage him. Nothing worked. Week after week. I'd drive 30 minutes to the school. only to sit with a little boy who didn't seem to care whether I was there or not. I was so frustrated.

One day. I noticed Sam wearing an Iron Man shirt. The next week, I brought a board game (棋盘游戏) featuring Iron Man characters. When I opened the box, his eyes lit up. He dove right in and played the game with me. As I was leaving that day, he looked up at me and said, "See you next week."

He and I built our relationship from there. I would spend his Friday lunch period with him. talking, playing games and just being a friend. Little by little, he opened up to me about his home life. His dad wasn't around. His mother supported the family by working nights at a local factory, so Sam's older sibling took care of him most of the time.

Right then and there, I wished to make sure the two of us always kept in touch—even after the program ended. Now it would be our last Friday lunch together. How could I make sure we had a great meal and he would still remember me?

So I looked for some inspiration for the perfect gift for him. A gift Sam would enjoy holding on to. On Wednesday, I was watching TV and a fast-food restaurant commercial came on, advertising the toy that came in the kids' meals—a small Iron Man toy.

Suddenly it hit me: Here was the idea I'd looked for!

At the school, I sat down with Sam and handed him the bag.
