The genetics of human eye color is much more complex than previously thought. according to a new study published recently.

An international team of researchers led by King's College London and Erasmus University Medical Center Rotterdam have identified 50 new genes for eye color in the largest genetic study of its kind to date. The study, published in Science Advances, involved the genetic analysis of almost 195,000 people across Europe and Asia.

These findings will help to improve the understanding of eye diseases such as pigmentary glaucoma and ocular albinism, where eye pigment (色素) levels play a role. In addition, the team found that eye color in Asians with different shades of brown is genetically similar to eye color in Europeans ranging from dark brown to light blue.

This study builds on previous research in which scientists had identified a dozen genes linked to eye color, believing there to be many more. Previously, scientists thought that variation in eye color was controlled by one or two genes only, with brown eyes dominant (显性的) over blue eyes.

Co-senior author Dr Pirro Hysi, King's College London, said: "The findings are exciting because they bring us to a step closer to understanding the genes that cause one of the most striking features of the human faces, which has mystified (使困感) generations throughout our history. This will improve our understanding of many diseases that we know are associated with specific pigmentation levels."

Co-senior author Dr Manfred Kayser, Erasmus University Medical Center Rotterdam, said: "This study delivers the genetic knowledge needed to improve eye colour prediction from DNA as already applied in anthropological (人类学的) and forensic (法医的) studies, but with limited accuracy for the non-brown and non-blue eye colours."

    The morning had been a disaster. My tooth was aching, and I'd been in an argument with a friend. Her words still hurt: “The trouble with you is that you won't put yourself in my place. Can't you see things from my point of view?” I shook my head stubbornly—and felt the ache in my tooth. I'd thought I could hold out till my dentist came back from holiday, but the pain was really unbearable. I started calling the dentists in the phone book, but no one could see me immediately. Finally, at about lunchtime, I got lucky.

    “If you come by right now,” the receptionist said, “the dentist will fit you in.”

    I took my purse and keys and rushed to my car. But suddenly I began to doubt about the dentist. What kind of dentist would be so eager to treat someone at such short time? Why wasn't he as busy as the others?

    In the dentist's office, I sat down and looked around. I saw nothing but the bare walls and I became even more worried. The assistant noticed my nervousness and placed her warm hand over my ice-cold one.

    When I told her my fears, she laughed and said, “Don't worry. The dentist is very good.”

    “How long do I have to wait for him?” I asked impatiently.

    “Come on, he is coming. Just lie down and relax. And enjoy the artwork,” the assistant said.

    “The artwork?” I was puzzled.

    The chair went back, suddenly I smiled. There was a beautiful picture, right where I could enjoy it: on the ceiling. How considerate the dentist was! At that moment, I began to understand what my friend meant by her words.

    What a relief!

    From self-driving cars to carebots (care+robots) for elderly people, rapid development in technology has long represented a possible threat to many jobs normally performed by people. But experts now believe that almost 50 percent of occupations existing today will be completely unnecessary by 2025 as artificial intelligence continues to change businesses.

    “The next fifteen years will see a revolution in how we work, and a revolution will necessarily take place in how we plan and think about workplaces,” said Peter Andrew, Director of Workplace Strategy for CBRE Asia Pacific.

    A growing number of jobs in the future will require creative intelligence, social skills and the ability to use artificial intelligence.

    The report is based on interviews with 200 experts, business leaders and young people from Asia Pacific, Europe and North America. It shows that in the US technology already destroys more jobs than it creates.

    But the report states: “Losing occupations does not necessarily mean losing jobs — just changing what people do.” Growth in new jobs could occur as much, according to the research.

    “The growth of 20 to 40 person companies that have the speed and technological know-how will directly challenge big companies,” it states.

    A 2014 report by Pew Research found 52 percent of experts in artificial intelligence and robotics were optimistic about the future and believed there would still be enough jobs in the next few years. The optimists pictured “a future in which robots do not take the place of more jobs than they create,” according to Aaron Smith, the report's co-author.

    “Technology will continue to affect jobs, but more jobs seem likely to be created. Although there have always been unemployed people, when we reached a few billion people there were billions of jobs. There is no shortage of things that need to be done and that will not change,” Microsoft's Jonathan Grudin told researchers.

    College graduation eventually means taking much of your attention in your first job search. This process can be challenging, especially for those students who had second thoughts about their chosen major and intended career path — or those who majored in a field not directly connected to a specific career. If you are in one of these groups, fear not! Although your major, coursework, and academic performance are relevant to landing a job, they are not the only deciding factors on where you can work. So, just how important is your major to your job search?

    Some majors are tied directly to specific career fields. For example, if you wish to become a teacher, you will likely have needed to complete an education program and eventually sit for a licensing exam. Successfully completing a specific major is very important to landing a job in the matching field.

    Other majors, however, are closely related to career paths but don't necessarily require a degree in the area. For example, students who majored in finance or math, may also have the necessary skills to be hired as an accountant.

    Lastly, there are many industries, such as professional sales, education (non-teaching positions), insurance, and customer service management, which hire new graduates from several more majors, looking for more generalized (笼统的) requirements. They may simply want to know the student has completed his or her bachelor's degree, which proves students' college-level math and writing, critical thinking, and problem-solving skills.

    Hopefully, as a college student, you were able to do more than just attend classes. Your non-academic experiences can be very influential on your future career as well. If you worked or volunteered during college and if you enjoyed these activities, seek out related careers. You may qualify for a position regardless of your major.

    Although it often seems like your college major alone determines your career fate, this just isn't the case. It may influence it, but there are other factors that influence your career options as well. If you don't know what career choices you have, talk to your faculty or academic adviser. You may be surprised at what opportunities await!

    Driving a car is not just handling controls and judging speed and distance. It requires you to predict what other road users will do and get ready to react to something unexpected. When alcohol is consumed, it enters your bloodstream and acts as a depressant (抑制药),damaging eyesight, judgment and co­ordination(协调),slowing down reaction time and greatly increasing the risk of accidents. Even below the drink driving limit, driving will be affected.

    Alcohol may take a few minutes to be absorbed into the bloodstream and start action on the brain. Absorption rate is increased when drinking on an empty stomach or when consuming drinks mixed with fruit juice. To get rid of alcohol from the body is a very slow process and it is not possible to speed it up with any measures like taking a shower or having a cup of tea or coffee.

    The present Road Traffic Ordinance states clearly that the limit of alcohol concentration is: 50 milligrams of alcohol per 100 ml of blood; or 22 micrograms of alcohol per 100 ml of breath; or 67 milligrams of alcohol per 100 ml of urine (尿液).

    Drivers who cause traffic accidents, or who commit a moving traffic offence or are being suspected of drink driving will be tested.

    Any driver found drinking beyond the limit will be charged. The driver declared guilty may be fined a maximum of HK $ 25000 and be sentenced to up to 3 years in prison and punished for 10 driving­offence points; or temporarily banned from driving.

    The same punishment applies to failing to provide specimens (样本)for breath, blood or urine tests without good excuse.

    Drink driving is a criminal offence. Be a responsible driver, think before you drink. For the safety of yourself and other road users, never drive after consuming alcohol.

    Your next car could have two seats, three wheels—two in front and one in the back and a top speed of more than 100 miles per hour. Elio Motors plans to make such a tiny car named the Elio. Its two seats sit front and back instead of side by side. The driver is positioned in the center with the passenger directly behind.

    The starting price for the car is just $6,800. It has only one door, on the left side, which cuts a few hundred dollars off the manufacturing costs. Having three wheels also makes it cheaper. It has air conditioning, power windows and door locks and an AM/FM radio. More features can be ordered through Elio's long list of suppliers. Elio will also sell the cars directly through its own stores and not through franchised dealers (特约经销商).

    Paul Elio dreamed as a kid that he would one day own a car company called Elio Motors. In 2008, tired of high gas prices, he started working on a car that burns gas in a more effective way. Equally important to him was creating US manufacturing jobs and making the car inexpensive enough to attract buyers who might otherwise be stuck in their old, unreliable cars. "Whatever matters to you, this can move the needle on it, he said.

    Already, more than 27,000 people have reserved one. Paul hopes to make 250,000 cars a year by 2020. So far, reservation holders are those who will use the Elio as a second or third car for work. Paul Elio believes the car will interest college students as well as used-car drivers who want something newer and more reliable, though.
