A new study, carried out by The American Automobile Association of America (AAA), has found that driver assistance systems fail to perform some actions in real-world test situations.
The experiments aimed to recreate common driving situations to measure the1 of the assistance systems. All of the four test models had systems designed to provide emergency stopping assistance.2 , they were built to help keep vehicles within a lane and to back up speed control systems. AAA said the test vehicles repeatedly3 on public roads when dealing with some real-world situations.
Separate tests were carried out in a4 environment off public roads. In those tests, all vehicles were able to5 stay in a lane and to recognize the presence of another vehicle entering into traffic. However, three out of four vehicles6 a test in which a lead vehicle changed lanes, causing a stopped vehicle to suddenly appear. AAA said in this test, each of the three cases required a driver to be involved to7 an immediate crash.
Automakers usually warn that the ability to8 a stopped vehicle after a lead vehicle changes lanes is a design limitation for driver assistance systems. But AAA's director of automotive engineering, Greg Brannon said vehicles had been expected to notice the stopped cars and react in time. Brannon said one reason for the9 could be that several manufacturers use the word pilot in the names of their systems. "Confusing vocabulary may lead someone to10 a system's capability, unintentionally placing the driver and others on the road at risk." He added.
Traditional Chinese medicine (TCM) is an ancient form of healthcare that dates back over 2,500 years, which aims to prevent or cure disease by maintaining or restoring yinyang balance. Fundamentally, TCM seeks to restore a dynamic balance between two complementary forces, yin (passive) and yang (active). According to the yinyang theory, a person is healthy when harmony exists between these two forces; illness, on the other hand, results from a breakdown in the balance.
TCM practitioners (从业者)look to treat the root cause of disease and take a holistic approach to helping people experience complete recovery without the use of conventional drugs. TCM is "holistic”' because it takes into account all aspects of a patient's life, rather than just several obvious symptoms. TCM practitioners view the body as a complex system, rather than separate organs. They use smell, hearing, touch, and pulse diagnosis (诊断)to discover the source of an unbalanced health condition. In addition, the practitioner typically makes use of what is known as five phases (wuxing). Using the five-phase theory, the practitioner can create a plan for treatment that might contain such components as herbs, lifestyle changes, and foods for recovery.
Over the past several decades, TCM has been going global. It is now practiced in 183 countries and regions with 86 of them signing agreements with China to promote it. More and more medical schools are now recognizing the importance of training students and staff in "mind-body" practices that emphasize disease prevention and holistic treatments. A study of 3,200 physicians, conducted by Health Products Research, indicates that more than 50 percent of physicians in the U.S. planned to begin or increase use of TCM.
Do you continue to be healthy in social isolation? NASA is looking for people to spend 8 months locked in a Russian lab for a new experiment.
When humans go to the moon and travel to Mars, they will need to be prepared for long-term space travel and even longer stays on these far-off destinations. Currently, NASA's Artemis program aims to land humans on the moon for the first time since NASA's Apollo 17 mission landed in 1972.
While the moon is the main goal of NASA's Artemis program, the agency's larger goal is to send people to Mars. But long-term space travel and habitation won't be easy. Such missions will present both physical and mental challenges as astronauts work to not only survive, but perform important scientific research in uniquely difficult environments.
In the upcoming NASA-Russia experiment, a group of people will live in a closed facility at Russia's Institute for Biomedical Problems, which is in Moscow. This habitat facility was used in2011 for notable series of Russian mock (模拟的) Mars missions known as Mars 500. During these missions, groups of people spent 520 and 105 days on two separate missions in the facility.
The facility, according to the statement, will have "environmental factors similar to those astronauts are expected to experience on future missions to Mars". The group of people will spend 8 months living together in isolation and working on scientific research.
By living and working in this Mars-like environment, participants in this study will help NASA researchers better understand the psychological and physiological (心理和生理的) effects of isolation. These missions help researchers not only perform relevant science experiments but also see how people might get on under strange conditions for long periods of time.
So, if you're finding that living in social isolation works for you, you might be particularly well-suited for living in a Mars-like environment and this could be for you. But first, you have to qualify. NASA is looking for "highly motivated" Americans between the ages of 30-55, who must speak both Russian and English fluently and have a Master of Science, Doctor of Philosophy, Doctor of Medicine, or military officer training. Applicants with other related experience may also be considered. Those who are chosen to be a part of this group will be paid for their work.

China has become the first country to land a spacecraft on the far side of the moon. The unmanned Chang’e-4 probe (探测器) - the name was inspired by an ancient Chinese moon goddess 61 (touch) down last week in the South Pole-Aitken basin. Landing on the moon’s far side is 62 (extreme) challenging. Because the moon’s body blocks direct radio communication with a probe, China first had to put a satellite in orbit above the moon in a spot 63 it could send signals to the spacecraft and to Earth. The far side of the moon is of particular 64 (interesting) to scientists because it has a lot of deep craters (环形山)， more so 65 the familiar near side. Chinese researchers hope to use the instruments onboard Chang’e-4 66 (find) and study areas of the South Pole-Aitken basin. ＂This really excites scientists,＂ Carle Pieters, a scientist at Brown University, says, ＂because it 67 (mean) we have the chance to obtain information about how the moon 68 (construct)＂ Data about the moon’s composition, such as how 69 ice and other treasures it contains, could help China decide whether 70 (it) plans for a future lunar (月球的) base are practical.

No woman can be too rich or too thin. This saying often attributed to the late Duchess (公爵夫人) of Windsor embodies much of the odd spirit of our times. Being thin is deemed as such a virtue.
The problem with such a view is that some people actually attempt to live by it. I myself have fantasies of slipping into narrow designer clothes. Consequently, I have been on a diet for the better -- or worse -- part of my life. Being rich wouldn't be bad either, but that won’t happen unless an unknown relative dies suddenly in some distant land, leaving me millions of dollars.
Where did we go off the track? When did eating butter become a sin, and a little bit of extra flesh unappealing, if not repellent? All religions have certain days when people refrain from eating and excessive eating is one of Christianity's seven deadly sins. However, until quite recently, most people had a problem getting enough to eat. In some religious groups, wealth was a symbol of probable salvation and high morals, and fatness a sign of wealth and well-being.
Today the opposite is true. We have shifted lo thinness as our new mark of virtue. The result is that being fat -- or even only somewhat overweight -- is bad because it implies a lack of moral strength.
Our obsession with thinness is also fueled by health concerns. It is true that in this country we have more overweight people than ever before, and that in many cases, being overweight correlates with an increased risk of heart and blood vessel disease. These diseases, however, may have as much to do with our way of life and our high-fat diets as with excess weight. And the associated risk of cancer in the digestive system may be more of a dietary problem -- too much fat and a lack of fiber -- than a weight problem.
The real concern, then, is not that we weigh too much, but that we neither exercise enough nor eat well. Exercise is necessary for strong bones and both heart and lung health. A balanced diet without a lot of fat can also help the body avoid many diseases. We should surely stop paying so much attention to weight. Simply being thin is not enough. It is actually hazardous if those who get (or already are) thin think they are automatically healthy and thus free from paying attention to their overall life-style. Thinness can be pure vain glory.

Although millions of us love our fitness trackers,the popular devices may not help as much,with weight loss as we think._61_article on the Mayo Clinic News Network says that one in five_62_(American) wears a tracker,but most aren't seeing the hoped-for（期盼的）results.
"Having an activity tracker doesn't_63_(necessary) translate into 'I'm a more fit person,'"says Kathleen Zeratsky, clinicial dietician（营养师）at Mayo,"or it's going to lead to automatic weight loss.An activity tracker is just a_64_ (help) tool."
In the report,Zeratsky says that the trackers do help_65_(keep) people be more aware of the need to be active, but that isn't enough.You need to burn more calories than you're taking in,and for most of_66_(we),that means a change in eating habits.
"If you're trying to lose weight,you want to have a calorie decrease from your activity,"she says."You don't want to destroy that by,say,_67_(reward) yourself with more calories with a rich meal."_68_other words,don't slow your progress by eating too much.
Zeratsky acknowledges that exercise can lead to hunger.But,she says,"if your body says 'I'm hungry' while you _69_(have) more activity,well,then just choose to eat in a smart way_70_won't damage your weight-loss efforts."
