2 . Are you looking for some informative magazines? The following ones can surely meet your needs.

Mental Foss is a magazine full of bite-sized（small bits） trivia（琐事）and mostly short articles with really interesting facts that you'll want to share with others. The writing is fun and friendly, so it’s easy to understand the answers to the more difficult questions, like: What does outer space smell like? Why isn't cat food mouse-flavored? While the print edition of the magazine stopped publishing in 2016, you can still read Mental Floss online.

Reader's Digest is not actually about books reading. Instead, it is about people. Inside you'll find anecdotes—short, personal articles about things that have happened to people. There are stories in simple writing about everything from funny celebrity moments and inspiring personal store to funny jokes and articles.

Cricket and Cicada are easy-to-read literary magazines aimed at teenagers. Each issue is full of wonderful short stories and poems, and beautiful illustrations. Even though these are technically children's magazines, they are perfect for learning English because they have high quality writing.

Time is one of the most well-known magazines in the world. Inside you'll find news, beautiful photographs and everything you need to get a" deeper understanding of the world in which we live. "Since Time is very high quality and provides deep insight on many serious topics, it can also be difficult for English learners to read. If you have trouble understanding Time, try Time For Kids, which has similarly great content but is written in a simpler way.

3 . Are you relatively skinny but growing a “beer belly”?

Then don’t be surprised at your next checkup if the nurse measures your waistline to determine your healthy weight. That’s because research is showing that a protruding (鼓出的) belly may be a sign of VAT — a dangerous form of fat around organs deep inside your body. “Studies confirm that visceral (内脏的) fat is a clear health risk,” said Dr. Tiffany Wiley, a senior expert at the National Institutes of Health in Bethesda, Maryland. Unlike the fat just under your skin, visceral fat raises your risk for heart disease. Experts think that’s because visceral fat raises blood pressure and inflames (使发炎) tissues and organs.

However, you can’t assume you’re safe from visceral fat if your overall weight is healthy, experts stress. That’s because you can have dangerous visceral fat even if you’re not considered overweight — and not have any visceral fat even if you are overweight.

How do you know if your stomach is protruding into dangerous size? Do a check. Non-pregnant women with a waist size greater than 88 cm and men with a waist larger than 102 cm, are at higher risk according to the US Centers for Disease Control and Prevention. If you’re Asian, it drops to 80 cm for women and 90 cm for men. But it is only a rough measure. “The only sure way to know is to check your visceral fat levels on a CT scan or MRI,” say experts.

According to the AHA committee, the most salutary physical activity to “shrink” belly is aerobic exercise. Aerobic means “with oxygen”, so aerobic exercise increases your breathing rate and promotes the circulation of oxygen through the blood. This type of exercise makes the heart work more effectively and improves its ability to move oxygen-carrying blood with every beat. Speed walking, jogging, stair climbing, cycling and swimming are all examples of aerobic exercise.

“However, more studies are needed to determine the best physical activity, food and other lifestyle changes to reduce heart disease risk,” Dr. Tiffany Wiley added.

4 . The SNAG stands for stereotyped nature-inspired aerial grasper and it’s a 3D-printed bird robot with claws. It can fly, stay on various surfaces catch and carry objects, just like the mighty falcon（隼）that was used as the source of inspiration in its development.

Each leg of the SNAG has two motors, one for helping it move back and forth, and the other one for grasping. Twenty printing attempts were necessary for the robot to finally reach its current structure, but it was worth it. Now, according to researchers, the flying machine has an impressively strong and high-speed clutch（离合器），being able to land and wrap its claws around a branch in about 20 milliseconds. SNAG has ankles lock, and there’s an accelerometer （加速计）on its right foot that reports that it’s landed while triggering（触发）a balancing process to stabilize it.

Scientists have already conducted several tests with the robot in rural areas and on different surfaces. In all the situations, the SNAG was able to catch objects thrown by hand, such as bean bags, a tennis ball, and more.

As for the applications of the bird-like robot, the SNAG can get attached to drones（无人机）and be used for search and rescue missions, wildfire monitoring, to offer just a few examples. Another great application is environmental research, with the SNAG also featuring a temperature and humidity（湿度）sensor. By using a robot that can act like a bird, you can unlock new ways of studying the environment, as explained by William Roderick, mechanical engineer and one of the researchers involved in the project. Now scientists are moving on to improving the robot’s situational awareness and flight control.

This isn’t the first time that nature has inspired groundbreaking technologies. We also wrote a piece recently about the F-SAM micro drone, which was inspired by the flight of samara（翼果）seeds, also known as “twisters” which have a special way of spinning down to the ground.
