Dry heat and steam baths had advocates in ancient Rome and pre-Columbian Americans used sweat lodges.The earliest saunas were probably underground

20、caves heated by a fire that naturally filled with smoke as chimney making was unknown at that time. a fire kept in a fire-pit would heat the rock walls of the cave.

30、iseasesA study by scientists in Finland has found that mobile phone radiation can cause changes in human cells that might affect the brain, the leader of the research team said.But Darius Leszczynski, who headed the 2-year study and will present findings next week at a conference in Quebec(魁北克), sai

31、d more research was needed to determine the seriousness of the changes and their impact on the brain or the body.The study at Finlands Radiation and Nuclear Safety Authority found that exposure to radiation from mobile phones can cause increased activity in hundreds of proteins in human cells grown

32、in a laboratory, he said.“We know that there is some biological response. We can detect it with our very sensitive approaches, but we do not know whether it can have any physiological effects on the human brain or human body, “ Leszczynski said.Nonetheless the study, the initial findings of which we

33、re published last month in the scientific journal Differentiation, raises new questions about whether mobile phone radiation can weaken the brains protective shield against harmful substances.The study focused on changes in ceils that line blood vessels and on whether such changes could weaken the f

34、unctioning of the blood-brain barrier, which prevents potentially harmful substances from entering the brain from the bloodstream, Leszczynski said.The study found that a protein called hsp27 linked to the functioning of the blood-brain barrier showed increased activity due to irradiation and pointe

35、d to a possibility that such activity could make the shield more permeable(能透过的), he said.“Increased protein activity might cause cells to shrinknot the blood vessels but the cells themselvesand then tiny gaps could appear between those cells through which some molecules could pass. “ he said.Leszcz

36、ynski declined to speculate on what kind of health risks that could pose, but said a French study indicated that headache, fatigue and sleep disorders could result.“These are not life-threatening problems but can cause a lot of discomfort, “ he said, adding that a Swedish group had also suggested a

37、possible link with Alzheimers disease.“Where the truth is do not know, “ he said.Leszczynski said that he, his wife and children use mobile phones, and he said that he did not think his study suggested any need for new restrictions on mobile phone use.（分数：15.00）(1).According to Leszczynski, how does

43、)Problems of InternetThe proportion of works cut for the cinema in Britain dropped from 40 per cent when I joined the BBFC in 1975 to less than 4 per cent when I left. But I dont think that 20 years from now it will be possible to regulate any medium as closely as I regulated film.The Internet is, o

44、f course, the greatest problem for this century. The world will have to find a means, through some sort of international treaty of United Nations initiative, to control the material thats now going totally unregulated into peoples homes. That said, it will only take one little country like Paraguay

45、to refuse to sign a treaty for transmission to be unstoppable. Parental control is never going to be sufficient.Im still very worried about the impact of violent video games, even though researchers say their impact is moderated by the fact that players dont so much experience the game as enjoy the

46、technical manoeuvres (策略)that enable you to win. But in respect of violence in mainstream films, Im more optimistic. Quite suddenly, tastes have changed, and its no longer Stallone or Schwarzenegger who are the top stars, but Leonardo DiCapriothat has taken everybody by surprise.Go through the most

47、successful films in Europe and America now and you will find virtually none that we are violent. Quentin Tarantino didnt usher in a new, violent generation, and films are becoming much more prosocial than one would have expected.Cinemagoing will undoubtedly survive. The new multiplexes are a gloriou

48、s experience, offering perfect sound and picture and very comfortable seats, thins which had died out in the 1980s. I cant believe weve achieved that only to throw it away in favor of huddling around a 14-inch computer monitor to watch digitally-delivered movies at home.It will become increasingly c

49、heap to make films, with cameras becoming smaller and lighter but remaining very precise. That means greater chances for new talent to emerge, as it will be much easier for people to learn how to be better film-makers. Peoples working lives will be shorter in the future, and once retired they will spend a lot of time learning to do things that amuse themlike making videos. Fifty years on we could well be m
