Living among trees, plants and flowers can fill your life with beauty. And if you are a woman, it can also help you live longer. Researchers found that women who live in homes surrounded by plants appear to have lower death rates than women who live in areas with fewer plants.

    Researchers at Harvard University's T.H. Chan School of Public Health reported the finding. They looked at the information from one of the largest and oldest investigations of the women's health: the Nurse's Health Study. It began 40 years ago. It now has information on nearly 200,000 women.

    For the new study, the team looked at the death rates of more than 100,000 women between the years 2000 and 2008. Then the researchers compared the death rates of these women to the plants around their homes. The researchers also considered other things, such as the age of the women, money they earn and race. They also looked at whether or not the women smoked.

    The study found that the death rate among women who lived in the greenest spaces was 12% lower than those from the least green areas. The researchers were surprised to find such a strong connection between high vegetation levels and low death rates.

    The study suggested that living among trees, flowers and other plants lowered levels of depression. Researchers said women in greener areas spent more time with other people and exercised more. It is common knowledge that plants can help the environment in many ways. The new finding also suggested ways to the government and the city planners to grow even healthier living areas.

    Asking for salary history provides an easy way to sort applicants into an employer's desired price range and helps the employer calculate the lowest offer that will still attract a candidate. But an increasing number of U.S. states and cities agree there ought to be a law against it. Massachusetts, Philadelphia, New York City and Puerto Rico have banned salary history questions on applications and in interviews.

    Why? Because when it comes to a candidate's suitability for a job, salary history is a subjective (主观的) and often misleading indicator — and it may most affect ＂the people who have already been illegally treated,＂ says Katie Donovan, a salary negotiation coach and one of the authors of the Massachusetts law.

    Candidates who start their careers underpaid because of the gender (性别) or race wage gap, a bad economy or a cheap boss finds that this lowball (虚报低价) figure continues to weigh them down throughout their career. At the same time, senior victims of layoffs have difficulty being hired because employers assume they're not interested in senior victims.

    In an interview, you can avoid talking about salary history questions by turning the discussion to what you're looking to make.

    Donovan recommends a method similar to what you're already doing: Enter $0.00, or some other number that is clearly intended not to cheat, but to oppose.

    Of course, there's always a risk doing so because it will cost you opportunities. But Ronda Wakefield, owner of NW MT HR Solutions, says that when she receives an application with an obviously false salary history, she'll still follow up if the candidate interests her. ＂I personally don't want to miss out on a great candidate because they didn't want to answer the question directly,＂ she says.

    Gesture is the use of such movements to express thought, emotion, etc. A gesture can be many things. Slamming a book shut shows anger and frustration. Opening a door lor someone shows kindness. Gestures go much beyond small actions.

    My friend once told me a story in high school. One day he met a girl who was on the girls' basketball team. He said hello, gave her a hard handshake and wished her good luck as she had a game later. He came to find out he saved that girl's life. She had planned on committing suicide and by shaking her hand and saying good luck, he made her realize someone really cared about her. I'm not saying all actions are going to change someone else's life that much, but it may make their day better.

    Gestures can be negative too. In my senior year of high school, a guy on my football team was late and was walking down the field to practice. Everyone on the team knows our coach hates it when people are late and walk on the field. He was walking in as if he owned the place and had no care of what his teammates were thinking. His body language had never been good. The other players on the team had never liked him because of his body language.

    Gestures can often say more than a person wants. One day I was mad at my parents for some pointless reason. All day I stayed downstairs. When one of them walked by, I would just stare at the TV or my phone and hope they wouldn't try to start a conversation. When they tried to talk to me, I would give one-word answers. Sitting on the couch and watching TV by myself all day was not my intent but that was what my gestures told my parents.

    One simple gesture can change a person's thoughts, day or maybe even save their lives. If everyone made a nice gesture to someone else every day, our school, town, and world would become a better place. One single act of random kindness at a time or a kind gesture can change the world.

    People love cellphones, which is why nine in ten Americans own one. But does heavy use of cellphones pose a risk of cancer? This question has caused controversy for many years. A new study in rats now augments those concerns. Its data linked long-term, intense exposure to radiation from cellphones with an increased risk of cancer in the heart or brain. The results have yet to be confirmed, the authors note.

    Indeed, although the rat study found a link between cellphone radiation and cancer, it offers no clues to why such a link might exist, notes Jonathan Samet. He teaches preventative medicine and directs the Institute for Global Health at the University of Southern California in Los Angeles. Still, he calls the new study's findings “significant”.They could lead to studies researching how cellphone radiation might cause cancer, he says.

    Phone signals are relayed between cell towers and cellphones via radio waves. This radio frequency—or RF—radiation is a type known as non-ionizing (非电离的).Unlike X-rays, non-ionizing radiation does not deposit enough energy into cells to release electrons from atoms or molecules, producing ions. So it tends to be far less harmful than ionizing radiation, such as X-rays. But that does not mean radio waves might not cause harm.

    In very large doses (量) this radiation will heat the body and cause tissue damage. But it's not yet known what much lower RF levels might do, such as those from cellphone use. Five years ago, the World Health Organization's International Agency for Research on Cancer, or IARC, concluded that cellphone use “is possibly carcinogenic (致癌的)”.

    Its conclusion was based on what little research data was available at that time. But notice that IARC was not certain. It said only that phone use might “possibly” cause cancer. So scientists at the National Toxicology Program, or NTP, investigated further.

    Petrol and diesel cars may still dominate our roads, but their days are numbered. A recent university study found that current electric cars could be used for 87 per cent of daily car journeys in the US. That figure could rise to 98 per cent by 2020.

One hurdle to the widespread adoption of electric cars has been ‘range anxiety'— drivers' concerns about running out of juice on a journey. While petrol stations are conveniently located across national road systems, the necessary network of electric charging stations is still being developed. That said, charging points are becoming increasingly common throughout the USA.

    Attitudes towards electric vehicles have changed quite considerably over the last few years. Not that long ago, electric cars were met with distrust, and their large price tags drove customers away. Thanks to improvements in battery capacity, recharging times, performance and price, the current generation of electric cars are starting to persuade critics. Plug-in cars will soon give internal combustion engine models a run for their money.

    As well as advancements on the road, electric vehicles are taking to the seas and skies. Electric boats are among the oldest methods of electric travel, having enjoyed several decades of popularity from the late 19th to the early 20th century before petrol-powered outboard motors took over. Now, the global drive for renewable energy sources is bringing electric boats back. Steps towards electric air travel are also being made, with Airbus and NASA among the organizations developing and testing battery powered planes. The experiments could soon make commercial electric flight a reality.

    Electric vehicles do not produce any emissions. Were the US to act on the study's findings and replace 87 per cent of its cars with electric vehicles, it would reduce the national demand for petrol by 61 per cent. However, because of the production processes and the generation of electricity required to charge these vehicles, they cannot claim to be completely emission-free. That said, as many countries continue to increase their use of renewable energy sources, electric vehicles will become even cleaner.
