Researchers at the Canadian Institute for Advanced Research show how the interaction (交互) between remembering and forgetting in the brain 1. (allow) us to make more intelligent decisions 2. (base) on memory. They published a new review paper in the journal Neuron.
Forgetting makes us smart by working with memorizing 3. the following ways, the researchers say. First, letting go of outdated information lets us adapt to new situations. By forgetting the old and potentially misleading information, we can adapt to new environments 4. (easy). Second, forgetting also makes decision- making simple. We just remember the important information which makes it easy for us 5. (make) wise decisions.
What and how much we remember can 6. (decide) by our environments, For example, a lawyer or a designer with a set of clients will likely remember 7. (they) names for a longer period of time, A cashier who has a changing sea of 8. (customer) every day will only remember names for a short amount of time.
The researchers point out that the motto is true: If you don’t use it, you lose it. But as 9. review paper shows, it can be a good thing. Clearing out the information you don’t need can help make room for the important things, 10. can make you become more intelligent.

A new study focuses on K2-18b, an exoplanet (系外行星) like the earth discovered in 2015, orbiting a red dwarf star (矮星) close enough to receive about the same amount of radiation from its star as the earth does from the sun.
Recently, scientists have discovered gas giants that have water in their atmospheres, but this is the least massive planet ever to have water detected in its atmosphere. ''The water detection was quite clear to us relatively early on, lead author Bjorn Benneke, a professor at the Institute for Research on Exoplanets at the Universite de Montreal, '' told Space.com in an interview.
Studies have suggested that planets with hydrogen-rich atmospheres could host certain forms of life, Benneke said. However, a news release reads: ''K2-18b's large atmosphere is extremely thick and creates high-pressure conditions, which likely prevents life as we know it from existing on the planet’s surface. '' While these researchers found evidence for liquid water clouds on K2-18b because of its lack of surface, rain wouldn't pour on the planet. Without a real surface, so to speak, landing on the planet would also be nearly impossible, especially because the gas is so thick and has such an incredibly high pressure that any earthr-created space-craft sent there would be devastated.
Benneke suggests that, possibly, this planet is formed by rock absorbing large amounts of gas, like a vacuum (真空) cleaner. This absorbed gas would have more than doubled the planet and increased its volume eightfold.
To come to these conclusions, the research team analyzed the data from Hubble Space Telescope observations that they made between 2016 and 2017 of the K2-18b planet passing in front of its star eight times. It allows scientists to detect distinct characters of water in a planet's atmosphere. This team plans to expand this research even further by studying K2-18b with NASA's James Webb Space Telescope, which is set to launch in 2021. This type of research, Benneke said, is leading toward a final goal of ''being able to study the earth-like planets. '' ''We are not quite there yet. '' he said, ''but this is really exciting. ''

The type of soap with the name African black soap or simply black soap is the one that has its origin in Africa or West Africa to be precise.
The soap is often made by women and is fair-traded, though not always, Black soap is traditionally made in West Africa, typically Ghana, from secret recipes. Different tribes have adopted their own secret making techniques, which can be seen in different colors among black soap. Varieties of black soaps actually made in Africa tend to be pure.
The first step of making traditional African black soap is selecting the plant—usually cocoa pods or palm tree leaves, sometimes shea tree bark (酪脂树皮), which then are sun-dried and burned to ashes which are often used to heal cuts. To guarantee the natural color and light smell, it's important to keep a constant temperature of burning. Then the water is added into the ashes along with the shea butter, palm oil, and coconut oil. That mixture is cooked until it becomes stable. It needs to be hand stirred for at least 24 hours. After that, they scooped it out and let it ''cure'' for two weeks. Those soaps that are made in Africa contain no artificial ingredients (材料).
African black soap is being used for many generations and many causes. African black soap has many benefits over commercially produced soaps. One of the most common usage is to cure skin conditions and problems. After using this soap, the skin looks healthy. Another usage of the black soap is for removing the makeup and dead skin. It also gives an excellent UV (紫外线) protection because of the high level of shea butter in it.

It was hot and yet, such a beautiful day. My parents and I picked up my grandmother from the nursing home. We used to go there regularly but the last time I visited my grandmother, she seemed to forget where she was and how to breathe on the massage (按摩) table—it scared me so I thought perhaps it was better to transfer her to a clinic that day.
She had been getting weaker and having aches from sitting in a wheel chair all day, so I called Wang Tao who runs a Chinese massage clinic with his wife and daughter out of their home and told him my concerns wasn't even sure whether my grandmother would be strong enough to get up the stairs or get onto the table.
''We can help her make it'', Wang Tao said. And, we did. Sure there were struggles and funny moments. For example, my grandmother wondered who was the man working on her back, Wang Tao had massaged her over the years at least 20 times. They used to laugh and talk together in Chinese but my grandmother didn't remember. Wang Tao was shocked that my grandmother seemed to have forgotten he is a Chinese man, but he still patiently tried to refresh her memory.
My grandmother was born in California, but her parents who were born in China only spoke Chinese, so Chinese was her first language but English is spoken all around her. Still, our family all felt grateful and happy to hear my grandmother start talking to Wang Tao in Chinese again. It was like the dust just needed clearing. We all laughed a happy laugh. When the session was over, my grandmother took Wang Tao's hand and thanked him for helping her. We ended our day with a Chinese dinner of course-one that ended with my grandmother saying to the massager: please come here and I have to shake your hand. ''Thank you for what you have done. '' she said joyfully as she held this stranger's hand. And then she turned to me, ''Thank you, my grandson. ''
