【推荐1】Nowadays hair loss is a common concern for many young people in China, and it can be caused by a variety of factors.     1    

One common cause of hair loss in young people is genetics. Male and female pattern baldness,is a hereditary (遗传的) condition that can lead to hair thinning and loss.     2     And it also features overall thinning of the hair in women.

In addition to genetics, certain medical conditions and treatments can also contribute to hair loss in young people. Conditions such as thyroid (甲状腺 )disorders, different diseases, and hormonal imbalances can all lead to hair thinning. Additionally, undergoing treatments such as chemotherapy or radiation therapy can result in temporary hair loss.

    3     Poor nutrition, too busy work, and certain hairstyling practices can contribute to hair thinning. For example, a diet lacking in essential nutrients, such as protein, iron, and vitamins,can impact the health of the hair and scalp (头皮).

    4     This includes tight hairstyles, frequent use of heat styling tools, and harsh chemical treatments. Additionally, emotional stress and mental health conditions can contribute to hair loss in some individuals.

To address hair loss in young people, it is important to identify the underlying cause. Consulting with a healthcare professional, such as a dermatologist (皮肤病医生) or trichologist.     5    

Treatment options may include topical medications, and hair restoration procedures.

In conclusion, hair loss among young people can be attributed to a variety of factors, including genetics, medical conditions, and lifestyle choices.

【推荐2】Maybe you recently lost your job. Maybe you broke up with your girlfriend.Or maybe a driver hit the back of your car and destroyed it.We all probably faced these situations at one time or another. Whether it’s one of the above or something else that got you down and made it difficult to get back up again, there is one quick and easy way to help you feel better. It’s called relativity.

Relativity is a psychological tool that helps people judge their situations from different viewpoints and minimize(最小化)feelings of self-pity. No matter what the negative situation is, it works really well to help someone recover from a hard time.

For example, you find yourself trapped in work assignments, hardly having time to come up for air. Your workload is eating into your personal life and even weekends. You’re unhappy, underpaid, and not getting time to rest. But how does this situation compare to someone that doesn’t have a job, or is homeless or can’t afford his family? All of a sudden, your crazy busy work life doesn’t seem all that bad. All of a sudden, you’re able to feel thankful that you have a job and have money coming in and that you have a roof over your head.

The point of using relativity is to show you that no matter how difficult your current situation is,there’s always someone who has a much worse situation. Relativity helps us understand that the grass isn’t always greener on the other side.

The best way to recover from a difficult situation is to use relativity to measure the situation. You’ll often find it’s never as bad as you had thought. This will immediately make you feel better and truly thankful for all that you have. After that, it’s time to outline the steps you need to take to get back on the horse. But wherever you find yourself right now, use relativity to make you feel better and help you walk down the path to your final goal.

【推荐3】Do you get your best ideas when you are bored, or when you are out doing new things? What should we look for when we want to be more creative? Boredom and stimulus (刺激物) may be opposites, but studies into creativity suggest that actually we might need both.

Writing for BBC Culture, Clair Thorp looks at the role that boredom plays in the creative process. Many writers and artists credit being bored with helping them have their best ideas —JK Rowling came up with Harry Potter while on a long train journey. Thorp tells us how some researchers believe that boredom drives our brains to find something to do—leading to creative ideas. So, maybe we should take the advice of the musician Questlove and learn to ignore the distractions that we can find on our phones.

However, before we all start planning how to bore ourselves into creativity, Sandi Mann, an academic and author, warns that too much boredom can take away the energy we need for creativity. Many experts talk about the importance of finding new experiences in order to be more creative. Actor and writer Kayode Ewumi recommends getting on a random bus and seeing where you end up or learning a new musical instrument as ways to avoid writer’s block. Professor Gerard Puccio, a professor of creativity studies, believes that having to look at new things, or old things in a different light, can force us to make unusual connections and come up with innovative solutions.

So, perhaps what we need is a balance—enough stimulus to make us look at things in different ways, and enough boredom to give us the breathing space to work through these thoughts.

【推荐1】Eating healthier may be as simple as not going to the grocery store, one study revealed. Participants who ordered their groceries online spent less money on junk food compared to when they shopped in person, according to the study. Researchers tracked the spending patterns of 137 shoppers over the course of 44 weeks. People who shopped online spent on average about $2.50 less on unhealthy food purchases like candy and frozen desserts compared to when they did their shopping inside stores, said study author Laura Zatz.

The study did not examine why shoppers spent less money on unhealthy food when they shopped online, there are some likely reasons, such as a reduction in opportunities for impulse (冲动) purchases. “Online shopping allows shoppers to keep away from lots of in-store marketing and attractive food stimuli (刺激), which encourages us to add items to our basket that we didn’t plan to purchase,” Zatz said. “Those towers of junk food at the end of grocery store aisles don’t exist online.” Besides, many people have presaved grocery lists, or their food options are based on their dietary needs, she added. Who we shop with may also play a role in our purchase, said Stephanie Rogus, professor of human nutrition at New Mexico State University. When shopping in person, adults often bring along their children or other family members, who may ask for unhealthy food.

Online grocery shopping is still relatively new, and Zatz said that marketing will evolve and influence shoppers to purchase unhealthy food online. Grocery stores may begin to advertise foods that aren’t selling as well in the form of pop-up ads or personalized recommendations to overcome reduced spending on certain items. If unhealthy foods are underselling, shoppers might start seeing ads for them.

Shoppers spent 44% more per transaction (交易) and purchased more items online versus in stores, researchers also found. Transaction fees could have influenced this trend, Rogus said. Many online grocery services have a transaction fee, so combining shopping trips to have fewer transactions could have saved the participants some money. At some stores, spending a certain amount could mean the fee is free. Most of the shoppers in this study were higher-income and could potentially afford to spend more money to avoid transaction fees or hit a required minimum payment for online orders.

The majority of food shopping was still done in person during the study’s time period, with participants shopping online just under 29% of the time. There is potential for online grocery shopping to reduce unhealthy food purchases, Rogus said, but the high percentage of times participants choosing to shop at a physical store means the full impact is unclear.

Online shopping can reduce the amount of money spent on unhealthy foods, but “people still need to make a wise decision to plan ahead and purchase a healthful and varied mix of foods consistent with a healthy diet,” Zatz stressed.

【推荐2】Migratory (迁移的) birds are specially adapted to find their way over extreme distances. Now, the new research of Kaspar Delhey and other researchers has discovered an unexpected way that migratory birds keep their cool during such backbreaking journeys: lighter-colored feathers (羽毛).

“We found across nearly all species of birds, migratory species tend to be lighter colored than non-migratory species,” said Delhey. “We think that lighter feather coloration is selected in migratory species because it reduces the risk of overheating when exposed to sunshine. Lighter surfaces absorb less heat than darker ones, as anybody wearing dark clothes on a sunny day can demonstrate! This would be particularly important for long-distance migrants that undertake extensive flights during which they cannot stop to rest in the shade.”

Delhey and his coworkers had been studying the effects of climate on bird coloration. Their earlier studies showed that, in general, lighter colored birds are found where temperatures are high and there is little shade. That’s in part because the birds’ lighter feathers help to keep them cooler in the hot sun. Then the researchers came across studies by others showing that some birds fly higher during the day compared to at night.

“Because flying higher is likely costly, these changes require an explanation,” Delhey says. “One possibility was that flying higher, where it is colder, would offset the heat absorbed by the feathers when the sun was shining.”

If so, they realized, another way to reduce the risk of overheating would be to absorb less solar radiation in the first place. It raised a question: have migratory species evolved (进化)   lighter feathers?

To find out, they did much research. Their findings show bird species get increasingly lighter as they migrate more. So, resident birds tend to be darker than short-distance migrants. Short-distance migrants are darker than bird species that travel farther. Delhey said the effect suited different types of birds. The same held true in waterbirds and ground-living birds, too.

The findings are another reminder of the important role of temperature and climate factors more broadly in the evolution of shaping the coloration of animals. They also help better understand the impacts of global warming and underlying adaptive evolutionary responses.
