Overheated property markets in major cities have started to cool down after authorities took measures against speculative buying and a potential home market bubble. However, a long-term effort is needed to make the market stable and sustainable, analysts said.

    Last month, new home prices dropped in seven cities, compared with six in September, according to the National Bureau of Statistics, which monitors housing prices in 70 cities nationwide. In Shenzhen, where housing prices rocketed by more than 30 percent in the past several months, prices declined by 0.5 percent in October.

    “After first-tier cities and some key second-tier cities launched cooling measures, home prices have obviously become stable,”Liu Juanwei, NBS senior statistician, wrote in a note posted on the NBS website.

    Beijing, Tianjin, Shanghai, Xiamen and Zhengzhou began to see home prices switching from rising to dropping in the second half of October, with average prices down by between 0.1 percent and 0.4 percent compared with the first half of the month, he noted.

    Housing authorities in more than 20 cities have launched various measures against speculative buying to curb rapid home price growth, including setting stricter requirements for qualified buyers and limits on buying second and third homes.

    Yan Yuejin, an analyst with property research agency E-House China R&D Institute, said the residential property market is “digesting these policies and measures gradually, and it is likely for the market to have rational and stable prices in the near future.”

    Ma Junwei, an analyst with Deyi Realty in Shanghai, said it will require a long-term effort by regulators and local authorities to battle speculative buying while keeping supplies stable for buyers with solid demand, including those who plan to buy their first home or upgrade their housing.

    In Shanghai, real estate agents said that they have noticed that homebuyers have become more rational. “Buyers are starting to take their time and study their options. They will compare prices, designs and locations and bargain with sales representatives,”said Luo Dingjun, sales manager at Jinyu Property Marketing.“This was not the case two months ago, when they rushed to buy for fear that if they hesitated, prices would grow too fast and they would no longer be able to afford. ”

    Loud cheers and applause broke out at NASA's Jet Propulsion Lab on Monday, November 25, 2018, as the unmanned lander, called Insight, touched down on Mars, after nearly seven years from design to launch to landing.

    The great arrival of the spacecraft­designed to listen for quakes and shakes as a way to discover the Red Planet's inner secrets, how it formed billions of years ago and, how other planets like Earth took shape­marked the eighth successful landing on Mars in Nasa's history.

    Minutes after InSight landed on the surface of Mars, the first image was sent back, showing a wide flat area as seen through a dirty camera.

    The touchdown came after a nearly seven-month, 300 million-mile travel from Earth to Mars, during which the InSight spacecraft had to slow down from a speed of more than 12,000 mph. The spacecraft's heat shelter helped the lander survive temperatures as high as 2,700℉.

    Each step along the way was watched nervously at JPL, with updates delayed by the eight-minute light travel time between Earth and Mars. Mission controllers hugged each other with joy when the signals were received. "We are proud of everything that has gone on today," they told us reporters.

    The first picture of the surface of Mars was sent back to Earth by one of the MarCO nanosatellites (马可纳米卫星) that accompanied InSight during its travel to Mars. The dust from the landing made the view unclear. Pictures from it were expected to be clearer once the dust settled and the lens cover (镜头盖) was removed.

    Hours later, InSight's batteries were charging as expected. The InSight team also passed on another picture, taken by a different camera that's fixed on the lander's robotic arm. The view is clearer, showing the robotic arm and the seismometer, which is used to discover the actual movement of the ground.

    Large gatherings such as weddings and conferences can be socially stressful. Pressure to learn people's names only adds to the stress. A new facial-recognition app could come to the rescue, but privacy experts recommend going on with caution.

    The app, called SocialRecall, connects names with faces via smartphone cameras and facial recognition, potentially avoiding the need for formal introductions. "It breaks down these social barriers we all have when meeting somebody," says Barry Sandrew, who created the app and tested it at an event attended by about 1,000 people.

    After receiving an invitation to download SocialRecall from an event organizer, the user is asked to take two selfies and sign in via social media. At the event, the app is active within a previously defined geographical area. When a user points his or her phone camera at an attendee's face, the app identifies the individual displays the person's name, and links to his or her social media profile. To protect privacy, it recognizes only those who have agreed to participate. And the app's creators say it automatically deletes users' data after an event.

    Ann Cavoukian, a privacy expert who runs the Privacy by Design Center of Excellence praises the app's creators for these protective measures. She cautions, however, that when people choose to share their personal information with the app they should know that there may be unintended consequences down the road with that information being used in another context that might come back to bite you."

    The start-up has also developed a version of the app for individuals who suffer from prosopagnosia, or "face blindness", a condition that prevents people from recognizing individuals they have met. To use this app a person first acquires an image of someone's face, from either the smartphone's camera or a photograph, and then tags it with a name. When the camera spots that same face in real life, the previously entered information is displayed. The collected data are stored only on a user's phone, according to the team behind the app.

    There have been many problems with our schools today, the biggest of which is closely related to our culture. In general, our culture, as represented in the media, gets excited by famous stars, and constantly stresses that it's what you have, not what you are, that counts. Parents are encouraged to be away from even very small children for most of the day. Too many voters go for politicians who would rather cut school funding than to get rid of tax cuts for the wealthy. All contribute greatly to the problems of educating our children.

    Today's teachers have to deal with a culture that is vastly different than in the past. They report that there is, among more children than ever, a lack of motivation, no drive to succeed or even try. The role models that boys view in the media mostly consist of men in comedies and other shows who are rude and often extremely immature; self-centered overpaid athletes; men in movies, television dramas, video games, etc. who are preoccupied with violence and power. As Leonard Sax wrote in "Boys Adrift", "Teenage boys are looking for models of mature adulthood, but we no longer make any collective effort to provide such models." Girls are attacked not only with such annoying images of males, but also with women who are preoccupied with appearance and are extremely materialistic.

    In such a cultural environment, it is more important than ever to have responsible, loving and caring parents who have enough time and motivation to devote to their children and see to it as their duty to model for them and raise them with high standards of honesty and responsibility along with tending to their physical needs. They need to care enough to see that their children are not attacked with the garbage that comes from movie, television and computer screens. In today's culture, they are basically alone in this effort since, unfortunately, so much is working against them.

    Until we, as a culture, face the truth about ourselves — that we are not providing adequately for a great many of our children — the storm will continue to rage over our education system.

Most teens can't wait to become adults, free to make their own decisions. But with freedom comes responsibility, and this applies especially to your finances. The earlier you begin developing good financial habits, the more secure your future will be. {#blank#}1{#/blank#}

Educate Yourself

To take charge of your financial future, read a few basic books on personal finance. {#blank#}2{#/blank#} And you will find it easier to say "no" to a friend who encourages you to waste money or classmates who plan expensive trips that you can't afford.

Plan Your Spending

 {#blank#}3{#/blank#} First, never spend more money than you can get, and second, watch where your money goes. The best way to do this is by creating a personal spending plan to track the money coming in and going out. 

Postpone Satisfaction

 {#blank#}4{#/blank#} However, you'd better prevent yourself from doing so. With more money saved, you can buy something even better. So whether you received money from a part-time job or special occasions like Chinese New Year, it is wise to hang on to your money so that you can enjoy a greater satisfaction later on. 

Start an Emergency Fund

To get ready for independence, you'd better save money for emergencies. So why not stick to a wise spending plan and put some money into this fund every month? {#blank#}5{#/blank#} It will also give you a sense of safety and enable you to sleep better at night. 

Managing money is a skill that takes time to develop. If you can form the habits of self-educating, planning and saving, you'll be on your way to a solid financial future.

A. There are two golden rules for you to follow.

B. Waiting to get what you want is called postponed satisfaction.

C. The best way to monitor your spending is to open a bank account.

D. Here are some habits that can help set you up for financial success.

E. This simple action will help you get out of unexpected financial problems.

F. Many teens rush to buy their favorite items as soon as they get some money.

G. Once you have learned enough knowledge, you won't be easily misled by others.

Researchers say they've used cutting-edge gravitational wave research to cast new light on a mystery—a 2000-year-old computer,the Antikythera mechanism found in shipwreck. 

Well over a century after its discovery,researchers at the University of Glasgow say they've used statistical modeling techniques,originally designed to analyze gravitational waves —ripples in spacetime caused by major events in the universe such as two black holes combining —to suggest that the Antikythera mechanism was likely used to track the Greek lunar year. In short,it's a fascinating collision between modern-day science and the mysteries of an ancient artifact. 

In a 2021 paper,researchers found that previously discovered and regularly spaced holes in a "calendar ring"were marked to describe the "motions of the sun,moon,and all five planets known in ancient Greeks and how they were displayed at the front as an ancient Greek universe. "Now,in a new study published in the Official Journal of the British Horological Institute,University of Glasgow gravitational wave researcher Graham Woan and research associate Joseph Bayley suggest that the ring was likely perforated (打孔)with 354 holes, which happens to be the number of days in a lunar year. 

The team used statistical models derived from gravitational wave research,a large-scale physics experiment designed to measure ripples in spacetime millions of light-years from Earth and Bayesian analysis,a technique using probability to quantify uncertainty based on incomplete data,to calculate the likely number of holes in the mechanism using the positions of the surviving holes and the placement of the ring's surviving six fragments. 

Surprisingly,the inspiration for the study came from a YouTuber Chris Budiselic,who has been attempting to physically recreate the ancient mechanism and investigating ways to determine just how many holes it contained. 

"It's a neat symmetry that we've adapted techniques we use to study the universe today to understand more about a mechanism that helped people keep track of the heavens nearly two millennia ago,"Woan said. 

"We hope that our findings about the Antikythera mechanism,although less supernaturally spectacular than those made by Indiana Jones,will help deepen our understanding of how this remarkable device was made and used by the Greeks,"Woan sadded.
