1 . 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.

2 . Japanese automaker Toyota says it will team up with the country’s space agency to develop a vehicle called the Lunar Cruiser to explore the moon. The name comes from a popular Toyota vehicle called the Land Cruiser. The company said it plans to launch the vehicle in the late 2020s. After that, Toyota said the vehicle could assist people living on the moon by 2040 and could possibly be sent to Mars as well.
Takao Sato heads the company’s Lunar Cruiser project. He told The Associated Press the vehicle is based on the idea that people eat, work, sleep and communicate with others safely in cars. He hopes theLunar Cruiser can serve the same purpose in space. “We see space as an area for our once-in-a-century transformation, ” Sato said, “By going to space, we may be able to develop telecommunications and other technology that will prove valuable to human life. ”
Another company, Gitai Japan Inc., is partnering with Toyota to develop a robotic arm for the Lunar Cruiser. It will be designed to perform jobs such as carrying out inspections and maintaining the vehicle. The company said the arm will be built to work with different tools. These tools could be used to study the moon’s surface more closely.
Interest in space has been growing in Japan in recent years. Japanese space exploration company iSpace announced last April that it would transport an explorer belonging to the United Arab Emirates (UAE) to the moon in 2022. Japan’s iSpace will provide the lander to carry the UAE’s rover(探测器).
The company plans to launch the lander on a Falcon 9 rocket built by American company SpaceX. Japanese citizens followed the trip to space last year of billionaire Yusaku Maezawa. He spent 12 days aboard the International Space Station. Maezawa also plans in the future to orbit around the moon on a SpaceX’s Starship spacecraft.
Toyota engineer Shinichiro Noda said he thinks the lunar project can extend the company’s tradition of serving customers to a place beyond Earth. He said Toyota currently has vehicles almost everywhere. “But this is about taking our cars to somewhere we have never been, ” Noda said.

4 . It might seem like something from a science fiction movie, but scientists today are working on ways to combine certain kinds of bacteria with tiny robots. Scientists want to use these creations to improve the way we give medical treatment. They claim that drug therapy (疗法), disease diagnosis, and even surgery could be greatly aided by the use of nanobiotechnology. Nano-means “tiny”, and bio-means “life”. This tiny technology will use living organisms in combination with electronics.
Electronics makers already use tiny robots to build complex but very tiny circuits. Medical scientists want to use these robots to repair patients’ damaged organs or to direct medicines to affect specific cells. For example, tiny robots could be engineered to deliver chemotherapy (化疗) directly to cancer instead of to the entire body.
Existing electronics are the right size, but they lack practical use. Robots that can be built small enough to enter a person’s cells would be too tiny to move on their own. Therefore, scientists want to use tiny organisms such as bacteria to act as vehicles for the robots. The bacteria will be “driven” through the bloodstream by magnetic pulses (磁脉冲). Once the bacteria are in the correct locations, the robots will be able to do their jobs. In theory, these robots will cause less damage to the body than traditional methods of delivering medicines or performing surgeries.
Nanobiotechnology has yet to be put into practice, but many people already have concerns about its use. Some people worry about the ethic (道德标准) involved with controlling live organisms—and the possible side effects for their human hosts.

5 . When someone is homeless or trying to recover from a natural disaster, they are in need of a lot of the basic life necessities that many of us take for granted (认为……是理所当然的). While people are often encouraged to donate canned goods, not everyone is thinking about things like shoes.
Of course, you can’t go looking for a new job or a home, if you have no shoes to walk in. One woman in Hays, Kansas took this into consideration, and found a way to help hundreds of people.
Payless stores were going out of business, and shoes were selling for as little as $1 per pair, so a woman named Addy Tritt bought out all the remaining shoes at the Hays Payless store—more than 200 pairs—and donated them to flood victims (灾民) in Nebrsska.
Those shoes were then included in a flood relief shipment taken to farmers in Nebraska by Fort Hays State University. Tritt, who recently graduated from FHSU’s human resources program, wanted to “pay it forward”.
“I have been so lucky,” she said. “There have been so many great people in my life who have inspired me. I see so many terrible things in the news. So many people have helped me when I was down. They influenced me so much that I want to help if I can.”
Tritt has a history of charitable (慈善发) acts. She has donated more than 60 bags of school supplies to Hays students, and organized a baby clothes drive and two supply drives for the animal shelter.
“I really feel I have been directed and guided to help people,” she said. “If you can do something for someone else, you need to find a way even if it is a pair of shoes.”

6 . Record-breaking. Abnormal. Dangerous. That’s how the National Weather Service described the heat wave hitting much of North America.
The heat wave has already broken all-time high temperature records in places unaccustomed to such extreme heat. For example, Oregon’s capital city, Salem, recorded the highest temperature in its history on Sunday: 130F, breaking the old mark by 4 degrees. The temperature hit 104F in Seattle. It was an all-time record for the city better known for rain than heat and was the first time the area reached such a high temperature since records began being kept in 1894.
Weather forecasters said the heat wave was caused by an extended “heat dome”which allowed hot air from the Gulf of Mexico and the Atlantic to stream northward over much of North America.
This current heat wave was yet more evidence of the impact of human-caused climate change. “When it comes to record-breaking heat events, the study has been run for event after event in region after region in year after year. And the answer is almost always the same,” said Kristie Ebi, a professor at the University of Washington “The days-long heat wave is a taste of the future as climate change reshapes global weather patterns.”
“Another aspect that we see connected to climate change but that we don’t hear about as much is the fact that there is also a lot more water in the atmosphere now. As we warm the oceans and warm the air, there is more evaporation（蒸发）and that wetter air makes us feel hotter,” added weather forecaster, Jennifer Francis. “A combination of high temperature and moisture（湿度）in the air means dangerous conditions for the young, elderly or others who are not healthy. Please drink plenty of water; stay out of the sun and in air-conditioned rooms.”

7 . Algorithms (计算程序) are able to do a huge number of tasks, and the number of tasks that they are able to do is expanding practically every day. According to a new study, despite increasing concern over the effect of algorithms in daily life, more and more people nowadays are willing to trust a computer program, especially if a task becomes too challenging. From choosing the next song on your playlist to choosing the right size of pants, people are relying more on the advice of algorithms to help make everyday decisions.
During the study, researchers asked volunteers to count the number of people of a crowd in a photograph and supplied suggestions that were offered by a group of other people and suggestions offered by an algorithm. As the number of people in the photograph expanded, counting became more difficult and people were more likely to follow the suggestions offered by an algorithm rather than count themselves or follow the “wisdom of the crowd”.
One of the common problems with AI is when it is used for awarding credit. While that is a subjective decision, there are lots of numbers there, like income and credit scores. Therefore, people feel like this is a good job for an algorithm. But we know that dependence leads to unfair and incomplete practices in many cases because of social factors that aren’t considered.
Facial recognition and hiring algorithms have come under inspection in recent years because their use has shown cultural prejudice in the way they were built, which can cause inaccuracies when matching faces to identities or screening for qualified job candidates. The prejudice may not be present in a simple task like counting, but their presence in other trusted algorithms is a reason why it is important to understand how people rely on algorithms when making decisions.
“The eventual goal is to look at groups of humans and computers making decisions and find how we can get them to trust each other and how that changes their behaviors,” one of the researchers said. “Because there is very little research in that setting, we’re starting with the fundamentals.”

8 . Going to sleep at a certain time is associated with a lower risk of developing heart disease, according to researchers. A team led by the U.K. -based University of Exeter found that going to sleep between 10 and 11 p.m. was beneficial compared to earlier or later bedtimes.
The research included 88,000 participants in the U.K. Biobank who were recruited between 2006 and 2010. The average age of the group — ranging from 43 to 79 years old — was 61 and 58 percent were women. Participants filled out demographic (人口统计的), lifestyle, health and physical questionnaires, according to a European Society of Cardiology news release. The study looked at the association between objectively measured sleep onset timing and cardiovascular disease using wrist-worn accelerometers, collecting a week’s worth of data.
Using Cox proportional hazards models, an age- and sex-controlled base analysis found that sleep on set time of 10 to 10:59 p.m. was associated with the lowest incidence of cardiovascular (心血管的) disease. Another model that controlled for sleep duration, sleep irregularity and established cardiovascular risk factors like smoking status and body mass index did not reduce the impact of the association.
There was a 25 percent higher risk of cardiovascular disease with sleep onset at midnight or later, a 12 percent greater risk for 11 to 11:59 p.m. and a 24 percent raised risk for falling asleep before 10 p.m. compared to sleep onset from 10 to 10:59 p.m. More than 3,170 cases, or 3.6 percent, were reported during an average follow-up period of nearly six years. Sensitivity analyses revealed the association with increased risk of cardiovascular disease was stronger in women, with only sleep onset earlier than 10 p.m. significant for men.
“The body has a 24-hour internal clock, called circadian rhythm (昼夜节律), that helps regulate physical and mental functioning,” study author David Plans of the University of Exeter said in a statement. “While we cannot conclude causation from our study, the results suggest that early or late bedtimes may be more likely to disrupt the body clock, with adverse consequences for cardiovascular health.”

9 . What you should know when applying for a credit card online
Applying for a credit card online can be awful, as you may have heard all sorts of information and might not know what to believe. Consider these tips when applying for a credit card online.
Who can apply for a credit card online
Online credit card applications are open to US adult residents -in other words, people with a mailing address in the US who are over 18 and either have a Social Security Number (SSN) or Individual Tax Identification Number (ITIN). Applicants under the age of 21 will need a co-signer or proof of income as part of the application process. While nearly anyone can apply for a credit card, note that credit card issuers evaluate applications based on many different factors and criteria. They are interested in getting a full picture of your financial health. Therefore, besides collecting your basic contact information, they will use your SSN to pull your credit report.
How to apply for a credit card online
Do your research. There are hundreds of different credit cards available with a variety of offers, fee structures and rewards programs. Chart your spending behaviors so you know which categories you spend most heavily in, and then shop around for the card that matches your credit profile and best fits your needs.
Follow internet security best practices. When you’re ready to apply, make sure both your web browser and operating system are up to date. Consider filling out the application on a mobile data connection or a safe, private network to prevent the risks of someone stealing your personal information. And if you have any doubt about the safety of an email from a card issuer, go directly to the issuer’s website rather than clicking on any links in the email.
