Teenagers are damaging their health by not getting enough sleep because they are distracted (分散) by electronic products in their bedrooms,according to a survey.
UK advice body The Sleep Council said “junk sleep” could rival (比得上) the consumption of unhealthy junk food as a major lifestyle issue for parents of teenage children. It brings no less harm than junk food to one’s health. Its survey of 1,000 teenagers aged 12 to 16 found that 30 percent managed just 4 to 7 hours of sleep as opposed to (形成对照) the recommended 8 or 9 hours by the experts. Almost a quarter said they fell asleep more than once a week while watching TV, listening to music or using other electronic products.
“This is an extremely worrying situation,” said Dr. Chris Idzikowski of the Edinburgh Sleep Centre. “What we are seeing is the appearance of junk sleep — that is sleep which is of neither the length nor quality that it should be in order to feed the brain with the rest it needs to perform properly at school.”
Nearly all the teenagers had a phone, music system or TV in their bedroom, with around twothirds possessing all three. Almost one in five of the teenage boys said the quality of their sleep had been impacted by leaving their TVs or computers on. The survey also found that 40 percent of teenagers felt tired each day, with girls aged 15 to 16 doing the worst. However, just 11 percent said they were bothered by the lack or bad quality of sleep.
“I’m surprised that so few teenagers make the link between getting enough good quality sleep and how they feel during the day,” Idzikowski said. “Teenagers need to wake up to the fact to feel well, perform well and look well; they need to do something about their sleep.”

Science is increasingly central to our lives — from its role in creating day-to-day objects such as the smartphones in our pockets, to the big challenges of tackling disease, addressing climate change and focusing on biodiversity loss.
Many of the changes that the discipline brings are hugely beneficial, but they often come with potential downsides that demand public debate. Will artificial intelligence take people’s jobs or destroy elections with false news? How fast can we practically achieve a net zero economy?
For the crucial public debate that is needed on all this to take place, we must have a scientifically literate population. But there is a divide between the scientifically minded and those who choose not to engage with science.
It saddens me that our culture now views science as difficult, which discourages many from taking an interest in it. A British Science Association (BSA) survey recently suggested that only around a third of 14- to 18-year-olds find scientists inspirational or consider the subject to be relevant to their lives.
In fact, science is interlinked with every aspect of our existence and people from all walks of life and of all ages should be able to access it easily. The invention of the printing press was crucial to the Enlightenment because it democratised (普及) knowledge. So, in this increasingly science-centred world, the same attention should be given to popular science writing as is given to other forms of literature.
The Royal Society Science Book Prize is the only one in the world to promote popular science writing. Stephen Hawking’s A Brief History of Time, which was shortlisted (把……列入入围名单) for the prize in 1989, was written for readers who had no prior knowledge of physics and has since become a universally recognised text on the universe.
Democratising science has never been more important. There are so many scientific stories to be told that can help us better understand ourselves. A society equipped with a solid understanding of the issues of the day is a society more able to respond to them in a better way.

It used to be that one followed in the footsteps of their father or grandfather or took over the family’s business when it came to making a career choice. These days, a career path can start anywhere and then veer off into something totally different.
Career choices must be realistic and well thought out. It is not uncommon for persons to start a career path and realize they have made a terrible mistake, feeling as if it may be too late to turn around. Not only does a career choice concern your strongest skills and interest, it is also something that you will be doing continuously to bring in income. This is why a career choice can be such a personal decision. Formerly it used to be unusual for someone to change occupations or careers more than once or twice in a lifetime; it is now even more unusual to keep the same career during someone’s working life.
There are a great many measures in helping one choose the right profession. A number of websites offering tools such as career tests and information, educational resources, resume services and the kind can be found. It is important for one to research one’s career in this changing economy situation, and choose the best from several related career choices.
