【推荐2】Jennifer Udler was in the middle of a 50-minute session with a patient when it started to rain. Walking and talking about anxiety and stress, she and her teenage patient got wet. But when they made it back indoors, Jennifer said, “Hey, look at us! We’re wet, but we got through it! Now you can use that next time you have anxiety before and during an event.” This kind of insight is key to her practice.

Jennifer, a social worker whose practice focuses on adolescents, has been a therapist(治疗师)for 20 years. For most of that time, she practiced in a traditional office, but she noticed how easy it was for her running partners to open up about their problems. After doing some research, in 2013, Jennifer founded Positive Strides Therapy, where she conducts sessions while walking outdoors. She conducts all of her sessions outdoors and in all kinds of weather.

“When somebody asks me if I specialize in walking therapy, I say, ‘No, that’s how I practice,’” Udler said. “I specialize in family systems theory. Walking in the park is just where I practice.”

Despite the lack of formal research, Jennifer believes strongly in the benefits, saying that it can be helpful. “We’ll be talking about ‘moving forward’ as we are actually moving forward on the path, building muscle memory of how they can move forward and leave the anxiety behind.”

And outdoor walking therapy doesn’t just benefit teens. Jennifer says the adults in her practice welcome the humanizing effect of taking therapy outdoors.

But it seems that these memories are not lost. They are still filed away in the brain somewhere; they just can’t be easily accessed.

Now, researchers at MIT have developed a means of getting back memories in mice suffering from Alzheimer’s. The method relies on a technique that uses light to control genetically modified neurons (转基因神经元). Currently it is too early to be used in human trials as it involves inserting light emitting (发光) equipment into the subjects’ brains, but the same principles still apply, the researchers said.

“The important point is that this is evidence of concept. That is, even if a memory seems to be gone, it is still there. It’s a matter of how to get it back,” said senior researcher Susumu Tonegawa.

The team took two groups of mice, one genetically engineered to develop Alzheimer’s and one healthy. They then placed them into a room and gave them a mild electric shock. All of the mice showed fear when put back in an hour later. When placed in the room a third time several days later, the Alzheimer’s mice acted normally. They had forgotten the shock.

The researchers were then able to bring back the memory of the shock by activating (激活) the cells in which the memories were stored. Even when the mice were put into an unfamiliar room, they showed fear when the cells associated with the shock were activated.

“Short-term memory seems to be normal, on the order of hours. But for long-term memory, these early-Alzheimer’s mice seem to be damaged,” said lead researcher Dheeraj Roy. “Directly activating the cells that we believe are holding the memory helps them get it back. This suggests that it is indeed an access problem to the information, not that they’re unable to learn or store this memory.”

Half of women is a lot of women, and yet, advertisers continue to behave as though they don’t exist. “The majority of marketing talks to adult women like they are all moms or want to be mothers,” Adrianna Bevilaqua, chief creative officer at M Booth, a public relations company, told The New York Times.

Industry experts explained to The Times that the absence of childless women in marketing materials is likely the result of inertia (惯性). Advertisers have long targeted moms because they buy their goods. In 2015, American moms were in charge of $3.4 trillion worth of spending decisions, which makes them the largest consumer group in the United States.

While they might not have the collective spending power of moms — many of whom, I suspect, would be very happy to give up some   power of choosing laundry detergent (洗衣粉) in exchange for power of choosing something else with equal pay — childless women also have the potential to improve a business’ bottom line. One report has found that they spend twice as much on beauty products as women with children, and spend 60 percent more time abroad. The Times also notes that they spend 35 percent more on groceries than moms.

Of course, advertising has had a long time to adapt to the ongoing change in gender (性别) roles, and still, brands has made sexist ads that many find degrading (降低品格的). And even when brands do try to get with the times, as is the case with Dove and Pantene, many women still think them unpleasant. These critics are angry about the way such campaigns overstate female empowerment when, in reality, such empowerment is far from being fully realized.

Earlier this year, ad agency Saatchi & Saatchi researched moms’ understanding of their representation in advertising and found that they weren’t happy either. They surveyed nearly 8,000 women from around the world, the majority of whom responded with feelings of frustration (挫败) at the outdated mom images, including the busy mom and the saintly (神圣的) and perfectionist mom we so often see. Above all, they resented the view of motherhood as a job. “Motherhood is about being, not doing,” said Mary Mills, worldwide director of strategic intelligence from Saatchi & Saatchi, when describing the findings.

So as it turns out, both childless women and moms are motivated by the same desire. They want advertisers to let go of motherhood as an all-consuming identity for women and instead present them as the varied and unique beings they’ve long known themselves to be.

【推荐1】For generations, depression has been seen as an illness, disorder or even weakness. Such an idea makes sense because depression causes suffering and even death. But what if we’ve got it all wrong?

The common wisdom is that depression starts in the mind with abnormal thinking. That leads to symptoms like headaches, stomachaches, or tiredness. Now, models like the Polyvagal Theory suggest that we’ve got it backward. It’s the body that detects danger and initiates a defense strategy meant to help us survive. That biological strategy is called immobilization, and it demonstrates in the mind and the body with a set of symptoms we call depression.

When we think of depression as unnecessary suffering, we are telling people with depression that they are not part of the group, they are not right and they don’ t belong. That robs them of hope. But when we begin to understand that depression, at least initially, happens for a good reason we lift the shame. Instead, people with depression are courageous survivors, not damaged sick people.

The autonomic nervous system (ANS) is constantly scanning our internal and external environment for signs of danger. If our ANS detects a threat or even a simple lack of safety, its next strategy is the fight or flight response, which we often feel as anxiety. Sometimes the threat is so bad or goes on for so long, that the nervous system decides there is no way to fight or to flee. At that point, there is only one option left: immobilization.

The immobilization response is the original biological defense in higher animals. It dulls pain and makes us feel disconnected. Think of some reptiles (爬行动物), which shut down their bodies to avoid cold temperatures and the lack of food and water. In humans, people often describe feeling “out of their bodies" during extremely unpleasant events, which has a defensive effect of reducing the emotional shock. This is important because some things are so terrible, we don’t want people to be fully present when they happen. What incredible capacity of our biology to find a way in hard times!

What moved Gaylord Nelson to action was the1969massive oil spill（溢出）in California,the largest oil spill in the United States at that time.The spill proved to be an environmental nightmare as it had a strong impact on marine life,killing an estimated3,500sea birds,as well as marine animals such as dolphins,elephant seals and sea lions.Inspired by the student antiwar movement at that period of time,Nelson found it was a right time to channel the energy of the students towards a fight for environmental protection.He decided that it was time to educate the Americans on the need to protect the environment.Thus,Earth Day was born in1970,and public environmental consciousness took centre stage.

On 22nd April 1970,millions of Americans took to the streets to demonstrate for a healthy,sustainable environment and thousands of students marched in protest of the terrible situation of the environment.Businesses were forced to follow environmental standards if they wanted to continue their operations.The year1990 saw Earth Day reach out to many more countries around the world.It helped pave the way for the 1992 United Nations Earth Summit in Rio de Janeiro,bringing together many nations,for a joint effort towards protecting the environment.In 2009,the United Nations decided to officially set April 22 as Earth Day.

For his role as founder of Earth Day,Gaylord Nelson was awarded the Presidential Medal of Freedom（1995）,the highest honour given to civilians in the United States.We honor the man,as the fight for a cleaner environment continues.
