    In 2006，Paul Letourneau of Worcester，Mass，lost his parents，his home and his pet dog.And that August，his life­long mild depression took a turn for the worse as he became suicidal(有自杀倾向的)．

    “I said I didn't want to be alive anymore，”Letourneau,67，recalled telling his best friend.

    He and his friend had gone for a walk when Letourneau stopped and asked his friend about ways to die painlessly.His friend advised him to admit himself to a hospital.

    “When I went back home，physically，I was shaking so much－and emotionally，I couldn't stop，”Letourneau said，“I knew I had to get help.”

    For many men，it takes a lot more than feeling down to recognize that they are depressed and then step through the doors  of a hospital，or a friend's or relative's home to ask for help.Men who are depressed usually refuse to get appropriate treatment，depression experts and patients say.

    “When men get depressed，the depression can be quite severe，”said Dr.lan Cook，professor of psychiatry at the Geffen School of Medicine at UCLA.“The challenge is getting men to acknowledge that they're depressed.”

    Depression affects about 15 million people in the United States，according to the National Institutes of Mental Health，and men get depressed about half as often as women.

    “It's unclear how much of this is a reporting bias，”Cook  said.“The stigma(耻辱)issues are somewhat different for men than they are for women.”

    “Men intend to consider that asking for help is a sign of  weakness，but when they can't complete the task of bringing themselves to the Promised Land，they become at risk.” said  Steven Lappen，who was once a depression patient.

    Science textbooks around the world have become suddenly out of date. Four new chemical elements(元素)have been added to the periodic table. A big decision now lies ahead-elements 113,115,117 and 118 need to be given their official names and symbols.

    New elements can be named after a mythical(神话的) concept, a mineral, a place or country, a property(性质) or a scientist. The names have to be unique and maintain “historical and chemical consistency”. This means a lot of “-iums”.

    “They're Latinising the name,” explains chemist Andrea Sella. “The most recent tradition is to name them after places or people.” The places chosen tend to be where the element was discovered or first produced.

    No one has yet named an element after themselves but many elements are named in honour of important scientists. Albert Einstein was given einsteinium. This can also be a way of righting the wrongs of the past. “Lise Meitner was really the chemist who spotted nuclear fission(核裂变)but she was never really recognised for it because she was Jewish and a woman, ” says Sella. “Giving an element a name that reminds us of her is greatly important. ”

    The naming process isn't quick. The scientists who discovered them will start things off by suggesting a name. But it will be down to the International Union of Pure and Applied Chemistry (IUPAC) to approve it. A special division of the US-based group has to accept the suggestion. Then there is a public review period of five months before the IUPAC gets the final approval. Once it's ready, the name is announced in the scientific journal Pure and Applied Chemistry.

    Naming an element is not just about functionality. Names are always important.

    Are you content with the shape of your nose? If not, the climate may be to blame, not your parents.

This is according to a recent study carried out by scientists from Pennsylvania State University, US. They found that climate played a key role in shaping our noses. The findings were based on an examination of the size and shape of noses of 476 people from four regions—West Africa, East Asia, South Asia and Northern Europe, using 3-D facial imaging technology.

     “People have thought for a long time the difference in nose shape among humans across the world may have arisen as a result of natural selection because of climate,” Arslan Zaidi, one of the lead authors of the study, told The Guardian. But while previous studies were based on measurements from human skulls, Zaidi and his team looked at nose shape itself.

    The result showed that wider noses are more common in warm and humid climates, while narrower noses are more common in cold and dry climates. That, Zaidi said, could be because narrower nasal passages help to increase the moisture (潮湿) content of air and warm it，which is easier on our lungs. This, in turn, led to a gradual decrease in nose width in populations living far away from the equator.

    More study is still needed to test the link between climate and nose shape, but Zaidi believes the current findings are valuable in understanding potential health issue. “As we become more of a global community, we are going to come across climates that we are not adapt to,” he told the Guardian. This means moving to a very different climate might increase the risk of breathing problems.

    However, he added, “This may not be necessarily true for various reasons such as of modern medicine and the fact that our current climate is very different from what it used to be.”

    If you're planning on travelling, there are a few simple rules about how to make life easier both before and after your journey.

    First of all, always check and double­check departure (起程) time. It is amazing how few people really do this carefully. Once I arrived at the airport a few minutes after ten. My secretary had got the ticket for me and I thought she had said that the plane left at 10：50. When I arrived at the airport, the clerk at the departure desk told me that my flight was closed. Therefore, I had to wait three hours for the next one and missed an important meeting.

    The second rule is to remember that even in this age of credit cards, it is still important to have at least a little of the local currency (货币) with you when you arrive in a country. This can be necessary if you are flying to a place few tourists normally visit. Once I arrived at a place at midnight and the bank at the airport was closed. The only way to get to my hotel was by taxi and because I had no dollars, I offered to pay in pounds instead. "Listen! I only take real money!" the driver said angrily. Luckily I was able to borrow a few dollars from a clerk at the hotel, but it was embarrassing.

    The third and last rule is to find out as much as you can about the weather at your destination before you leave. I feel sorry for some of my workmates who travel in heavy suits and raincoats in May, when it is still fairly cool in London or Manchester, to places like Athens, Rome or Madrid, where it is already beginning to get quite warm during the day.

Cuyahoga Valley National Park Volunteer Program

Building a Community of Park Stewards

    Position Title: Wildlife Volunteer — Butterfly Monitors (2 positions)

    Dates: Mid May to September, 2020

    Hours: 8-16 hours/ week

    Location: Cuyahoga Valley National Park

    Duties: Park staff will train volunteers in butterfly identification and data recording for one week before volunteers work in team of two to help track butterfly monitoring areas. The three butterfly monitoring areas in the park are I to 2 miles in length and are walked one time per week. Butterflies are identified by using binoculars (望远镜) or by netting and releasing. Data is recorded on data sheets.

    Skills required: Applicants must have self motivation and desire to work with others. Volunteers will work during days when temperature is 70 degrees or more, between 10:30 am and 5 pm. Ability to walk a long distance in hot and humid conditions is needed. Skills with basic butterfly identification are not a must but helpful.

    Requirements: Applicants must be current Kent Stale University (KSU) students and a National Park Service Agreement must be completed. U. S citizenship is also required.

    How to Apply: Please request an application from Mike Johnson at gkovach@ kent.edu and send it back to Mike Johnson at gkovach@ kent.edu, by February 15, 2020. If offered an interview, please come to Cuyahoga Valley National Park with your personal resume introducing your education and previous work experience.
