The FDA is the common name for the Food and Drug Administration. It is a government agency that makes consumer goods safe. It regulates food and the food supply. It also controls diet supplement. The FDA also makes sure that drugs and medical devices are safe and effective.
For drugs and medical machines to be accepted, they must go through a lengthy process. There are many strict tests. First, anything that humans use must be tested on animals. This may take up to 6 years. Then, it must be tested with a few people. Testing on 15 to 20 people can last up to a year and a half. Third, a mid-sized group (100 to 500 people) is used. This often takes two years. Then a large group is tested over 3 years. Of 5,000 drugs discovered, only 5 enter trials. Of that, only one passes on to the market.
Food supplements like ginseng (人参) follow a different path. The FDA does not pre-test them as they do for drugs. The agency only controls these products if they are unsafe but are already being sold. Two exceptions are baby and medical food. Because those that use them are not strong, the FDA is more careful with these products.
Labeling(标签) is a major focus. A label must show what a product is for. For drugs, labels should say the name of the drug and what it is used for. It should also detail who should take it and list any side effects. It needs to detail directions for pregnant women, children, or old people. It also needs to detail safety information.
The FDA protects the public from harm. It achieves this through controls and labeling. It has standards for effectiveness in medical products. It also has standards for how information is shared.

On an average day most of us check our smartphones 47 times, and this habit clouds our judgment on what information to select and store, which might explain why it’s time we should do things about the information we take in to form memories.
As simple as it sounds, the repetition of tasks-reading, or saying words over and over — continues to be the best method for transforming short-term memories into long-term ones. To do that, we have to retrain our minds to focus on one task at a time. Sadly, most turn a blind eye to this formula because we believe we’re productive. New connections are made in your brain when you learn, so to remember what you learn, do what you probably did in your youth: Repeat words, thoughts and ideas over and over until you get them right.
Also, spaced repetition might be the best way. Quickly pushing facts into our brains leads us to forget them in the long term. When you review knowledge and practice it often, it sticks, a research has shown. So if you can include what you’re trying to remember into daily life, ideally over time, your chances of keeping it significantly improve. But once you stop reviewing that knowledge, the retention (保留) drops greatly. To get past it, space out your repetition over a few days and test the effect yourself. But be careful: find a healthy interval that works. This is a good way to effectively start tackling a new language.
Sometimes, memory and focus usually go hand-in-hand. Dr. Cowan suggests rearranging our office setup as one way to improve focus. “The rebirth of the open workplace cannot be helping stay on task, ” Dr. Cowan said. Referring to work spaces without desks, physical barriers and privacy, but with a lot of playthings.
Multiple studies have found that procrastination (拖延) leads to stress and completely kills focus. Stop engaging in useless tasks like surfing the web and just handle whatever it is you need to work on. Then watch your focus increase quickly and your memory improve.
Memory is very cue (提示) dependent, “Mr. Schacter, a psychologist, said, referring to”. Something he calls absent-minded memory failure. “Most say it could never happen to me, but it’s a very long list of responsible people that it has happened to. When you don’t have that cue, you can forget almost everything.”
A simple way around that is to set reminders. Even better, combine a few of these techniques: Write your reminder on a post-it and put it on your desk so you’re forced to repeatedly look at it over a long period, including the practice of spaced repetition.

I’d done it before, and so I had no reason to believe that this time would be any different. I was sure that when I returned home from my mission trip. As always, I’d bring back nothing more some mud on my boots. A hole or two in my jeans and, of course, a lot of great memories.
The summer before my high school graduation, I went to West Virginia with others as volunteers to repair the homes of those in need. Arriving at our destination, my group was assigned the task of rebuilding sections of a home that had been damaged by fire. No sooner had we parked on the home’s dirt driveway than we saw an excited little girl, no more than six years old, standing in the doorway of the family’s temporary home. Shoeless and wearing dirty clothes and the biggest smile I’d ever seen, she yelled, “Ma, Ma, they really came!” I didn’t know it then, but her name was Dakota, and four more days would pass before she’d say another word near me.
Behind Dakota was a woman in a wheelchair — her grandmother, we’d soon learn. I also discovered that my job that week would be to help change a fire-damaged dining room into a bedroom for this little girl. Grabbing our tools, we went to work. Over the following days, I noticed Dakota peeking at us every now and then as we worked. A few times, I tried talking with her, but she remained shy and distant, always flying around us like a tiny butterfly but keeping to herself.
By our fifth and final day, however, this was about to change.
Before I went to work on her home on that last morning, I spoke for a moment or two with the grandmother. I was especially pleased when she told me how much Dakota loved her new room — so much, in fact, that she’d begged to sleep in it the previous night, even though it wasn’t quite ready. As we talked, I noticed something I hadn’t seen before — Dakota was hiding behind her grandmother.
Cautiously, she stepped into view, and I could see that just like her clothes, her face was still dirty. But no amount of soil could hide those bright blue eyes and big smile. She was simply adorable. I wanted so much to hug her, but respecting her shyness, I kept my distance.
Slowly, she began walking toward me. It wasn’t until she was just inches away that I noticed the folded piece of paper in her tiny hand. Silently, she reached up and handed it to me. Once unfolded, I looked at the drawing she’d made with her broken crayons on the back of an old coloring book cover. It was of two girls — one much taller than the other — and they were holding hands. She told me it was supposed to be me and her, and on the bottom of the paper were three little words that instantly broke my heart. Now almost in tears, I couldn’t control myself anymore — I bent down and hugged her. She hugged me, too. And for the longest time, neither of us could let go.
By early afternoon, we finished Dakota’s bedroom, and so I gladly used the rare free time to get to know my newest friend. Sitting under a tree away from the others, we shared a few apples while she told me about her life. As I listened to her stories about the struggles she and her family went through daily, I began to realize how boring various aspects of my own life were.
I left for home early the next morning. I was returning with muddy boots and holes in my Jeans. But because of Dakota, I brought back something else, too—a greater appreciation for all or the blessings of my life. I’ll never forget that barefoot little butterfly with the big smile and dirty face. I pray that she’ll never forget me either.

People think of cats as cute. But research published in a psychology journal calls them neurotic (神经质的) and unstable. Researchers from the University of Edinburgh in Scotland and the Bronx Zoo in New York compared the personalities of domestic house cats with those of four different types of wildcats.
To better understand their personalities, the researchers rated a number of animals behaviors on what psychologists call the Big Five human personality traits (特征).
Domestic house cats have similar personality structures to African lions. “It’s what cats do pretty much on a daily basis, things like being anxious, being timid, being excitable, being aggressive toward humans, being aggressive toward each other, ”said Max Wachtel, a Denver psychologist who didn’t participate in the study. “All of those are characteristics you see in those cute little house cats, and you also see them in lions.”
If you ever thought your cat was anxious, insecure, tense, suspicious or aggressive toward you, you aren’t making it up, he said. If they were bigger, they probably would consider killing you.
But the news isn’t all bad: Just like lions, house cats are also playful, excitable and impulsively funny. They just aren’t very predictable. One moment cats will be enjoying bell scratches, and the next they will be biting you to make you stop.
“It is good to understand the personality characteristics of our pets,” Wachtel said “Different cats have different personalities, but as a species, there are a lot of commonalities.”
The researchers also studied personality traits of Scottish wildcats and some other animals “Across the five species we assessed, personality structure was strikingly similar and also seemed to be related to other studies’ findings, such as in tigers,” the researchers wrote in their study in the November 2014 issue of the Journal of Comparative Psychology. But house cats were most like lions, potentially because they live in semi-social surroundings and lions are the most social of cats.
“They’re cute and furry, but we need to remember when we have cats as pets, we are inviting little predators into our house,” Wachtel said. “Cats can be fantastic, sweet companions—until they turn on you.”
