Recently, a cartoon created by studentsfrom China Central Academy of Fine Arts put this group of people under the spotlight. In the short film, phubbers with various social identities bury themselves in their phones. A doctor plays with his cell phone while letting his patient die, a pretty woman takes selfie in front of a car accident site, and a father loses his child without knowing about it while using his mobilephone. A chain of similar events eventually leads to the destruction of theworld.

    Although the ending sounds overstated the damage phubbing can bring is real.

    Your health is the first to bear the effect and result of it. “Constantly bending your head to check your cellphone could damage your neck,” Guangming Daily quoted doctors as saying. “the neck is like a rope that breaks after long-term stretching.” Also, staring at cellphones for long periods of time will damage your eyesight gradually, accordingto the report.

    But that's not all. Being a phubber could also damage your social skills and drive you away from your friends and family. At reunions with family or friends, many people tend to stick to their cellphones while others are chatting happily with each other and this creates a strange atmosphere, Qilu Evening News reported.

    It can also cost you your life. There have been lots of reports on phubbers who fell to their death, suffered accidents, and were robbed of their cell phones in broad daylight.

    Stop wasting your time thinking of reasons for your failures and shortcomings.  Instead, realize that the seeds of success were planted within you when you were born. Only you have the power to make those seeds grow.

    The seeds, and the power to grow them, are contained in the most awesome machine ever created: the human mind. Success is a choice and not a chance. You were born a winner. You were born rich. You can be a success if only you make the right choice.

    You cannot be successful without first developing your self-esteem (自信心). Your level of self-esteem is always based on the degree of control that you are able to exercise over yourself, and thus over your life. People with low self-esteem are people who do not believe that they have any power，or responsibility for their lives. They are always victims. They are leaves tossed (摇摆) by the winds of chance blown about with any sudden change in the weather.

    You can exercise control over your life only to the degree that you believe you are responsible for everything that happens in your life.  Failures think that everything happens by accident and chance. Successful people realize that they are responsible.

    Everything happens as a result of something.  If we can identify the cause，we can control the effect. We are responsible for what we choose to think and believe. One generally rises to the level that one expects. We are responsible for setting our expectations. Our success is dependent upon our level of confidence.

    If you associate with positive-thinking people，you are definitely going to achieve success. On the contrary，the opposite happens. We are responsible for finding，planting，and nurturing (培育) the seeds that contain future victory, born from setbacks (挫折).

    In short, in all areas of your life，whether they are financial, physical, emotional, or spiritual, you are responsible. Once you recognize this, accept it, and firmly believe it. You are on the road to success.

    Since the 1970s, scientists have been searching for ways to link the brain with computers. Brain-computer interface (界面) (BCI) technology could help people with disabilities send commands to machines.

    Recently, two researchers, Jose Milan and Michele Tavella from the Federal Polytechnic schooling Lausanne, Switzerland, demonstrated(展示)a small robotic wheelchair directed by a person's thoughts.

    In the laboratory, Tavella operated the wheelchair just by thinking about moving his left or right hand. He could even talk as he watched the vehicle and guided it with his thoughts.

    "Our brain has billions of nerve cells. These send signals through the spinal cord(脊髓)to the muscles to give us the ability to move. But spinal cord injuries or other conditions can prevent these weak electrical signals from reaching the muscles," Tavella says.  "Our system allows disabled people to communicate with external world and also to control devices."

The researchers designed a special cap for the user. This head cover picks up the signals from the scalp(头皮) and sends them to a computer. The computer interprets the signals and commands the motorized wheelchair. The wheelchair also has two cameras that identify objects in its path. They help the computer react to commands from the brain.

    Prof. Milan, the team leader, says scientists keep improving the computer software that interprets brain signals and turns them into simple commands. "The practical possibilities that BCI technology offers to disabled people can be grouped in two categories: communication, and controlling devices. One example is this wheelchair."

    He says his team has set two goals. One is testing with real patients, so as to prove that this is a technology they can benefit from. And the other is to guarantee that they can use the technology over long periods of time.

    Global warming threatens to hold back human progress, and make unachievable all UN targets to reduce poverty, according to some of the world's leading international and development groups.

    In a report published today, Oxfam, Greenpeace and other groups say rich governments must immediately address climate change to avoid even “unbearable levels” of worldwide poverty.

     “Food production, water supplies, public health and people's livelihoods are already being damaged and weakened,” the report says. “There is no approach possible. The world must meet its commitments to achieve poverty reduction and also deal with climate change, which are closely linked.”

    The report, which draws on UN predictions of the effects of climate change in poor countries over the next 50 years, says poor countries will experience more flooding, declining food production, more disease and the extinction of entire eco-systems on which many of the world's poorest people depend.

     “Climate change needs to be addressed now. The poor will bear the great consequence of it. The frontline experience of many of us working in international development indicates that communities are having to fight more extreme weather conditions.”

    Climate change will cause great damage to agriculture and water supplies and will increase diseases. “By 2025 the number of the world's population living in countries of significant water stress will almost double, to 6 billion people. Tropical (热带的) and sub-tropical areas will be hardest hit — those countries already suffering from food shortage”.

    Poor countries mostly do not need hi-tech solutions, but would most benefit from education, research and being shown how to farm better. The report says unchecked global warming, more than wars or political upheaval (政变), will displace millions of people and unsettle many countries.

    Camping -Yellowstone National Park

    Camping rules

    Camping or parking in picnic areas, picnic grounds，or any place other than a designated (指定的) campground is not permitted. However, camping is often allowed in neighboring communities and forests outside the park.

    Camping is limited to 14 days between June 15 and September 15 and to 30 days the rest of the year. Check - out time for all campgrounds is 10:00 am.

    Quiet hours

    Camping in Yellowstone is a special experience. Each visitor deserves the opportunity to hear the birds, wildlife, and streams in this beautiful environment. Respect the rights of other campers and obey the law by keeping quiet from 8:00 pm to 8:00 am. No noises will be allowed during this time.

    Golden Age/ Golden Access discounts

    Holders of Golden Age and Golden Access permits will be given about 50% discounts on camping fees.

    Croup camping

    Group camping are permitted at Madison, Grant and Bridge Bay campgrounds from late May till the closing date for large organized groups with a designated leader such as youth groups or educational groups. The fees change per night, depending on the size of the group. Advance reservations (预定) are required and can be made by calling (866) 439 -7375.

    Are you a morning person? You might not like the findings in this new research.

    From a lack of air and drinking water to solar radiation, theoretical Mars pioneers face any number of potential obstacles to settling on the red planet. Now, scientists have found something else to add to the list: seriously messed-up biological clocks.

    One day on Mars - which scientists refer to as the solar day, or “sol”- is 37 minutes longer than a day on Earth. A team of European scientists recently demonstrated why that could be a problem.

    Circadian rhythms are the body's natural cycles of rest and waking, which tend to follow roughly 24-hour light-dark cycles. These natural rhythms - which play a role in biological functions including brain wave activity and hormone production - can be interrupted by things like jet lag（时差）and night shift work.

    For the study, the researchers compared mice with healthy, 24-hour circadian clocks to mice with a genetic change that caused them to have shorter, 20-hour circadian clocks. The mice with healthy biological clocks were more likely to survive and reproduce, while the mice with shorter biological clocks were more likely to die off.

    What does this all have to do with space travel? Since the Martian sol is longer than a day on Earth, people with shorter circadian clocks could suffer from health problems as they try to adapt to the rotational speed of the red planet.

    Unfortunately, the body is unlikely to adapt to the new conditions or “learn” to develop a longer clock. As Loudon explained,“ Learning is not a likely option.”

    In other words: Sorry, super-early risers - NASA might not want you for the next Mars mission.
