Humans are not the animal world's only fashion followers. Tits (山雀) can be one of them, too. A study by Sonja Wild and Lucy Aplin shows that, given the chance, they make their nests (巢穴) with this season's must-have color.

Dr. Wild and Dr. Aplin followed up on a study which noted that the blue tits preferred to put the same plants into their nests. This also suggested fashion-following—and it led Dr. Wild and Dr. Aplin to imagine that birds were studying the nests of others and copying them. 

The birds they followed carried instruments on them. That allowed researchers to follow a large number of tits by their arrival at food dispensers (自动取物装置) throughout the woods. 

One day in March 2021, Dr. Wild and Dr. Aplin used five dispensers with wool rather than food. Each contained two colors—either orange and pink or blue and purple—but all were rigged to give only one of these. This remained so until at least one local nest was seen to include wool from a dispenser. At that moment, the other color was discovered, too. As a comparison, Dr. Wild and Dr. Aplin set up four wool dispensers in a separate area, each providing two colors from the beginning. 

Of 68 tits' nests, 26 included wool from a dispenser. Of these, 18 were built after both colors had been gotten from all dispensers. Even so, 10 of that 18 included only the color of wool first chosen by a nest makers. By contrast (相比之下), all 8 nests with wool have mixed colors, which showed a clear difference in the record.

Tits, then, do seem to be "in fashion" when it comes to nest-building materials. Tits like those of the leaders of human fashions and it is worth more deep research.

The characteristic (特征) of shyness is to feel frightened and nervous in new social situations or when being the center of attention. Whether shyness is part of your children's personality or just something they feel when they are in front of a group of strangers, it is a common experience, according to a study.

To look at shyness, researchers brought 152 children aged 7-8 into a lab and told them they would give a speech, which would be filmed and shown to other children. The study showed that about 10% of the children showed a level of stress over time when giving the speech. About 25% of the children were not reported to be shy in the eyes of their parents, but in fact showed a level of social stress from giving the speech. This finding provides the fact that shyness may be a part of these children's temperament (性情).

For children at this age, shyness may be a quite common and normal experience when they face a speech task. For a smaller group of shy children, however, being the center of attention may be stressful at different times and environments. 

A shy temperament isn't always valued by society like an outgoing personality, but that doesn't mean there is something wrong. Everyone can feel shy at times depending on the environment. And those who are particularly shy often have happy social lives—they just aren't likely to be the liveliest people in a crowded room.

Although shyness itself may not necessarily be a problem, parents should pay attention to signs of worry, particularly in their shy children. Importantly, however, we know that not all shy children are the same, and that many shy children grow up to be well-balanced adults.

The world will become a better place when we realize that everyone can have bad days and that we care enough and take actions. A Kansas fourth-grade teacher Rachel Harder recognized this, and she found an amazing way to help out both her students and their families. 

A few years ago, Rachel attended a trauma (精神创伤) conference. She learned that some police stations partnered with schools. They could let teachers know when their students need help, patience or extra care. 

A year after the conference, Rachel had a student with autism who frequently had difficult days. To support the student, Rachel told the student's mom to simply text her "Handle with Care" to let her know when the student was experiencing difficult time. "When she would text me, I knew that her daughter needed some extra time and a quiet place to get help, not going to the playground for morning announcements (通告), so that the rest of her daughter's day went well," Rachel said.

The simple method was such a success that Rachel decided to send all of her students home with a note for their parents. It explained what the "Handle with Care" system was and how they could make use of it. In no time, the parents began to show their appreciation for Rachel's unbelievable act of kindness.

But Rachel's kindness didn't end with her class. News spread of the amazing system, and teachers across the country began giving it a shot in their own class. Printed materials could be found on the school website, and the feedback (反馈) has been extremely positive!

A British sleep expert, professor Chris Idzikowski, did a research showing that there was some connection between the way people sleep and their personality.

The fetal position

The fetal position gets its name from the shape of a baby in the mother's stomach. It is the most common position in the world. People who sleep in the fetal position tend towards worry and anxiety. They are often shy and sensitive. In the fetal position, a sleeper's body is like a ball as he lies on one side with legs and arms bent. Adults usually sleep in this position. 

The starfish position

When sleeping like a starfish, you lie on your back with arms up near the pillow. Sleep scientist Idzikowski says starfish sleepers value friendship. People who sleep in this position are good listeners and quick to help others. If you have a starfish sleeper as a best friend, you're in luck. Starfish sleepers are great listeners and a source of comfort to others.

The freefall position

In the freefall position, sleepers have their hands on or around their pillows, with their heads turned to one side. Freefall sleepers are social but sensitive and can become upset by extreme situations. They like to be in control of everything around their life. It's all part of their long periods of indecision, but once they make a choice, they stick to it. This position can aid in digestion (消化).

The log position

For those who suffer from back pain, the log position could be helpful for you. Log sleepers have both their arms and legs extended, so their bodies are straight like a log. Log sleepers are very trusting, but are usually social and easy-going individuals. Idzikowski claims that preferring a log position suggests that a person is sociable and can communicate with others easily.

When we think about vitamin C, all guess that we're talking about oranges, right? Well, that's not (complete) the full story about this awesome vitamin. Cancer prevention, heart health and immune (免疫) function boosting are a few roles vitamin C (play) in keeping us healthy. Apart vitamin pills and powders, fruits and vegetables are our best sources (need) for this super vitamin. Cabbage, as an example, is great source of vitamin C. But do you know that red bell peppers have almost 50% (many) vitamin C than oranges?

Many kinds of fruits like strawberries also carry rich vitamin C and are quite not difficult  (eat) when we know they can help us fight off that common cold everyone will catch around seasonal changes. Just a few (fact) bounce around our head about some of the foods high in vitamin C that can boost our immune system, help our heart  fight off those terrible cancer cells. 

However we phrase it, it is hard to find a reason not to boost our vitamin C intake after seeing all the  (amaze) benefits it can give to us.
