1 . If you want to do your kids a favor, consider having them walk to school. Walking to school provides many benefits – improving academic performance, reducing anxiety, boosting spirits, better sleep, a sense of independence, having an opportunity to familiarize oneself with a neighborhood, to notice small details, to feel a sense of wonder at the surroundings. The list goes on.
Parental fears still exist, however. Parents are terrified of cars, of injury, of harsh weather, of encounters with strangers and wild animals. These fears prevent parents from letting their kids do something that's actually enormously beneficial to them, despite the fact that removing an opportunity to be active contributes to an increase in childhood obesity, which can have a greater negative impact on a child's life than the risk of being injured due to being active.
How do we go from being a society that does not encourage its children to walk independently to being one that does? Parents must face their own discomfort with letting go. Brussoni, an expert who researches children's outdoor and risky play, said "We want to move parents from focusing solely on protecting their child to building trust in their child’s abilities and strategies to support their child’s skills in navigating the streetscape."
Schools can play a role by encouraging children to walk to school. Brussoni offers additional suggestions: "They should promote a culture that walking to school is the norm, help educate parents on why this is important, and consider closing the streets around the school to cars before and after school."
Parents might do well to put themselves in their children's shoes. As adults, we know how good a morning walk feels to start off a day or to end one. Walking energizes us and cheers us up, and it can do the same for children. As we go through this pandemic that has shaken up all of our lives, it's a good time to practice new routines and establish new habits. Walking to school is a great place to start.

2 . I was on vacation with my husband, my brother, his wife and daughter. We were not familiar with the area and jumped onto a bus, thinking it would be a nice way to see the downtown’s old town area. Well, until visiting with the bus driver, we found out we were on the neighborhood route which picks up school children and delivers to various neighborhood places, with a route of well over about 2 hours. That was a surprise and a concern because we had parked our vehicle in a timed parking area and it was going to end.
We shared this with the bus driver only to let her know we were not from the area and apologized for getting on her bus in error. Then she surprised us further saying, “I get off shift after a few more blocks, and if you don't mind a tight squeeze in my company car, I'd be happy to take you back to your vehicle before the time is over.” The bus driver received permission from her manager, so we gratefully said yes to her offer.
She went out of her way to take us back to our vehicle after her shift was over and it wasn't on her route to home either. We were touched and grateful for her kindness and thoughtfulness. In return because she had shared some of her concerns about the school-age children she sometimes had on the bus route, I shared with her a little tip on how to quiet the children with an energetic technique that would make the ride safer for them as well as for her. She was so grateful. It was a wonderful exchange of kindness!

3 . The Japanese government, citizens and groups are debating what to do with radioactive water from the disabled nuclear power plant near Fukushinma. An earthquake on March 11, 2011 caused severe damage to three of the six nuclear reactors at the Fukushinma Daiichi Nuclear Power Plant. Since then, Japanese officials have been trying to contain and clear up the damage.
The Associated Press recently observed the decontamination (净化) process taking place there. Officials are trying to decide what to do with 1.2 million tons of radioactive water being stored at Fukushinma. The nuclear center is operated by the Tokyo Electric Power Co. , or TEPCO. The company says it needs to free up space as work on the damaged reactors reaches an important point. Many people expect TEPCO to slowly release the water into the ocean near the nuclear center. The government has already approved the plan.
However, it is not clear when the company will carry out the plan. Local people oppose it because that could hurt the fishing industry. Sales of fish caught off the coast near Fukushinma are half what they were before the nuclear disaster. Fish caught in the area have been approved for sale after radioactivity testing by health officials.
TEPCO Chief Decommissioning Officer Akira Ono said the water must be removed. He says crews need the space currently occupied by the water tanks. In their place, workers will set up structures to hold melted reactor wreckage(反应堆残骸).
People wear protective clothing and head coverings to work in the most radioactive areas around the nuclear center. But underground conditions remain dangerous and radioactive water is leaking from the melted reactors and mixing with groundwater. This water is being pumped into containers to keep it from flowing into the sea. The polluted water from underground is processed and filtered to remove dangerous radioactive elements. Tritium(氚) is the only radioactive material that remains. Japan's industry ministry and nuclear officials say tritium is not harmful in small amounts. However, although officials try to ease public fear, there are worries that fish might be affected if the water is released into the sea.

4 . You know that squeak(吱吱声)you hear from your pet mouse or the pest mouse? It turns out that it is 'not really a squeak, but a sweet song by male mice to attract females. This is the conclusion reached by biologist Dustin Penn and his team at the Veterinary University of Vienna.
The scientists who have been conducting a series of studies on house mice for a number of years, began by recording the high-pitched(声调高的)sounds male mice made the moment they sensed a female mouse around. What they discovered when they played them back to females was that the ladies could tell between those made by their brothers and the ones made by unrelated males. Just like human, they tended to ignore the ones made by their brothers.
The researchers then took the experiment one step further and analyzed the squeaks. To their surprise they discovered that while the squeaks sounded similar, they each had a different "tune". The biggest surprise of all was that the mice could even learn tunes from each other.
However, not all scientists agree with this finding. Some like Kurt Hammer, a scientist at the German Primate Center believe that the test sample was too small to make such a conclusion.
The researcher's next plan to test if the females care about the quality of the “song”. In some bird species, males that can sing the most complex tunes seem to get the most attention.
So why do we care whether mice can sing or not? Clearly, since they are being used as laboratory testers, it will help us make advances in human speech disorders like the ones found in people suffering from autism(自闭症).

5 . Anyone who commutes(通勤)by car knows that traffic jams are an unavoidable part of life. But humans are not alone in facing potential backups.
Ants also commute—between their nest and sources of food. The survival of their habitats depends on doing this efficiently.
When humans commute, there’s a point at which cars become dense(稠密) enough to slow down the flow of traffic, causing jam. Researchers wanted to know if ants on the move could also get stuck. So they regulated traffic density by constructing bridges of various widths between a colony of Argentine ants and a source of food. Then they waited and watched, trying to find out at what point they are going to have a traffic jam.
But it appears that that never happened. They always managed to avoid traffic jam. The flow of ants did increase at the beginning as ants started to fill the bridge and then levelled off at high densities. But it never slowed down or stopped, even when the bridge was nearly filled with ants.
The researchers then took a closer look at how the behaviour of individual ants impacted traffic as a whole. And they found that when ants sense overcrowding, they adjust their speeds and avoid entering high-density areas, which prevents jams. These behaviors may be promoted by pheromones, chemicals that tell other ants where a trail is. The ants also manage to avoid colliding(碰撞) with each other at high densities, which could really slow them down.
Can ants help us solve our own traffic problems? Not likely. That’s because when it comes to getting from point A to point B as fast as possible, human drivers put their own goals first. Individual ants have to be more cooperative in order to feed the colony. But the research could be useful in improving traffic flow for self-driving cars, which can be designed to be less like selfish humans—and more like ants.
