Space travel is definitely bad for astronauts’ bones, reducing their bone density(密度) after only a month of weightlessness, according to French research published on Friday. Laurence Vico and his fellow workers at St Etienne University called for more research into the effects of microgravity, after their study of 15 astronauts from the Russian MIR station showed bone loss continued throughout space flights.

“Bone loss was especially striking in four astronauts, ” the scientists reported in the Lancet Medical Journal. They measured the bone mineral density (BMD) of bones in the forearm and lower leg of the astronauts who had spent one to six months in space. The BMD loss was significant in the tibia(胫骨) of the lower leg, a weight-bearing bone, but barely changed in the radius(桡骨) of the forearm. “Our results indicate the need to investigate not only on different bones, but also in different areas of the same bone since not all sites of the skeleton are similarly affected by space conditions, ” they added. Without gravity the body isn’t bearing any weight so there is no need for calcium (钙) which makes bones strong, and it becomes empty into the bloodstream. The research team suggested in future scientists should try to determine if the loss of bone density was only on weight-bearing bones on longer flights, also the possible recovery after returning to Earth.

You've got a problem. You're going to go to university in a different town and you need somewhere to live. Or perhaps you just don't get on with your parents. What can you do? Have you ever thought of sharing a flat?

　　 I know all about it because I've been sharing flats for the past four years, since I moved to Edinburgh to study. I must admit my first experience was a bit of a disaster. I saw an advertisement in the newspaper from a girl who had a flat and was looking for a flat mate. When I met her, she seemed really nice, and I noticed that she had lots of great CDs I wanted to hear and a big TV. However, I changed my mind about her a few days after I moved in. I came home from college one day and threw my books and jacket onto the living room sofa. My flat mate looked at them, looked at me and shouted: "I hope you're not going to leave those there!" It was then I found out that she was absolutely obsessive(着魔似的) about being tidy. It was obvious that we were incompatible(合不来), as I'm definitely not the world's tidiest person. I moved out after the first month.

　　 I then decided to try sharing a house with several people. I rented a room in a big old house, which I shared with four other girls (two Brazilians，a Russian, and an Italian). It was great because the house was always full of young people from all over the world and we had lots of parties. However, there were three problems. Firstly, it was almost impossible to do any work because the house was so noisy. Secondly, there was only one bathroom, and there was always someone in it, especially first thing in the morning when I was already late for class. But the biggest arguments we had were always the day the phone bill arrived!

　 　After a year the foreign girls went home, and I decided to look for a new, preferably quieter flat! This time I decided to share with a friend, somebody I already knew well. We’ve been living here now for nearly a year and we get on really well -- except for her irritating habits of eating my yogurts(milk) and finishing the coffee! But it's great having someone else to help pay the rent, to share their dinner with you when you're too exhausted to cook, and who, unlike your parents or your partner, doesn't mind what time you get up or if you've left your bedroom in a mess. And best of all, when you've had a bad day or you've broken up with your boyfriend you know there's always someone to talk to.
