Study shows why your dreams are so weird WASHINGTON, Oct 13: A study involving people with amnesia, a popular computer game and sleep experts may help explain why dreams are so weird and so important, experts have said. They said people with amnesia who played the popular computer game Tetris dreamed about the images it invoked, but could not remember actually playing the game. And, unlike people with normal memories, they never really got any better at the game. This shows that when the brain is filing away the memories it needs to keep, it has to go through a series of steps, and dreaming is a manifestation of one crucial step, Dr Robert Stickgold, a psychiatrist at Harvard Medical School in Boston, who led the study, said yesterday. Dreams are just the bodys way of clearing out the mental "in-box", Stickgold said. "The trick is to move it to the file cabinet and to file it in the right place," Stickgold said in a telephone interview. "A lot of REM (Rapid Eye-Movement) dreams, those really quirky, strange, bizarre dreams that we have late at night, is the brain looking for ways to cross-index. It is looking for cross references - does this fit with this. Sometimes it does and sometimes it doesnt," he said. When it doesnt fit, the dream seems weird, he said. When the cross-reference is a good one, the brain can reinforce the memory. One way to test this is to look at people who are missing one of those vital memory steps people with amnesia. Stickgold had noticed that when he skied, he had vivid dreams about it. "When you go downhill skiing, when you go to sleep, you can feel the turns," he said. This would make a good test, he said, but added he knew he would never get the okay to take first-timers downhill skiing for a scientific experiment. And then someone mentioned Tetris, a computer game that uses vivid images of falling and rotating shapes that have to be manipulated by the player. It, too, evokes dreams, Stickgold said. "I play Tetris, that is all I see going to sleep," he said. Writing in todays issue of the journal science, Stickgold and colleagues said nearly two-thirds of the 27 volunteers they asked to play Tetris had dreams about it. Their group included five people with amnesia, caused by disease, stroke and other accidents. Experts at the game and first-time players were also tested. Strange images follow bouts with computer game people in both groups reported that, as they fell asleep, they dreamed about images of blocks falling and rotating, as they do on the computer screen when the game is in progress. They did not actually dream about the game itself. The amnesia patients did not remember playing the game and they did not ever improve, unlike the volunteers with normal memory. Three of them did report the strange dreams, however. "What these results, especially from the amnesics, tells us is that when the brain puts dreams together, it does it without knowledge of and access to memories of actual events in our life," Stickgold said. "We have two different memory systems. The hippocampal codes information on events from our lives. So when I ask you what did you have for breakfast, you go to the hippocampus for the answer," he added. "A second system is the neocortical," he said, referring to another area of the brain. "So when I ask you when we go out for breakfast what do you like for breakfast?, that is a different type of question. When you go for that general information you go to neocortex. An amnesic can tell you what they like for breakfast. They cant tell you what they had for breakfast." This is because their hippocampus is damaged. The findings suggest that the brain does not go to the hippocampus to get images for dreams, but to the long-term, neocortical system, the researchers said. (REUTERS) |
Children of male nuke workers not at risk: Study LONDON, Oct 13: Babies fathered by men who are monitored for radiation exposure at work are no more likely than other children to die during pregnancy or suffer birth defects, British scientists said today. "Our overall findings are reassuring," Pat Doyle, one of the scientists, said in a statement. "The main message from this work is that men exposed to radiation at work in the UK nuclear industry do not father pregnancies with increased levels of adverse outcome." The genetic effects of exposure to low levels of radiation have been a source of concern in the past because scientists believed it may generate abnormalities in sperm which could have adverse effects on children. "The theory has always been that male nuclear workers may be at risk of fathering children that may be deformed, have cancer or suffer from a congenital disease in childhood," said Andrew Traherne of Britains Leukaemia Research Fund. Doyle, Moreen Maconochie and colleagues from the London School of Hygiene and Tropical Medicine, as well as Eve Roman of the Leukaemia Research Fund, analysed pregnancies reported by British nuclear industry workers. The study in the lancet medical journal concentrated on male workers because they far outnumbered female workers. A small number of female nuclear industry workers were included in the study and analysis seemed to indicate a slightly higher risk of foetal deaths or defects. "Although the statistics showed a slightly higher risk among monitored mothers, with numbers as small as these it would be hard not to rule this out as a chance finding or due to other factors not addressed in this study," Maconochie said. A previous study revealed that children born to nuclear industry workers were not at increased risk of developing childhood cancer. The researchers analysed employees at the Atomic Energy Authority, atomic weapons establishment and British nuclear fuels. About 11,700 men and 1,900 women reported one or more pregnancies conceived after employment in the nuclear industry. Men reported 23,676 pregnancies and women 3,585. (REUTERS) |
PLA military develops counter measures BEIJING, Oct 13: The Chinese Peoples Liberation Army (PLA), the worlds largest standing Army, is capable of winning a possible "future high-tech war" by developing weapons to counter stealth planes, cruise missiles and armoured helicopters, the state media claimed today. "The PLA started this morning the largest ever show of military training achievements since its 1964 largescale contest of military skills at its major site at the foot of Beijings Yanshan mountain," Xinhua news agency reported. Quoting authoritative sources, Xinhua said the two-day show, witnessed by Chinese President Jiang Zemin will focus on new "three striking" items and new "three defending" items. The new striking items include striking at stealth planes, cruise missiles and armoured helicopters while the defending items were defending against precise striking, electronic interference and detecting surveillance. The old striking items and defending items of the riking at tanks, planes, airborne troops and defending against atomic, chemical and biological wars. The show includes field training, on-line contest and theoretical exchanges, the report said, adding it also has three sub-sites in inner Mongolia autonomous region, northeast China and waters of the Bohai sea. Over 10,000 PLA men are participating in the training show involving fast-responding troops, amphibian armoured forces, digital artillery forces, special armed forces, marine corps and other PLA units.

China attacks Nobel prize for Chinese writer BEIJING, Oct 13: China dismissed as mere politics today the award of the Nobel literature prize to blacklisted Chinese novelist and playwright Gao Xingjian. The Foreign Ministry said in a statement that giving the 2000 prize to Gao "shows again the Nobel literature prize has been used for ulterior political motives, and it is not worth commenting on". Gao, who lives in france and has French citizenship, became the first Chinese to win the Nobel prize for literature in awards announced yesterday. The Foreign Ministry statement, the first official reaction from China, suggested the Nobel committee had ignored far worthier Chinese writers to make a political point. "As we all know, China has a long history and brilliant culture," it said. "No matter in history or in modern China there are many world-famous outstanding works of literature and literary giants." Gao, 60, whose work has been banned from Chinese theatres and official publications since 1986, left China the following year and settled in France as a political refugee. "It is a great happiness, a great luck. I have not had time to realise what this will mean for my life," Gao told Reuters television at his home in a Paris working-class district. "I am an artist. I live among my paintings. Writing is a luxury for me," Gao said in the fluent French of his adopted country. Mai Ping Chen, a friend of Gao, told Reuters in Stockholm: "It will be very good support for the exiled Chinese writers. He cannot go back to China. His name is on the blacklist." The academy refused to comment on the politics of awarding the worlds most prestigious literary prize to a writer who is persona non grata in his homeland. "We have no geographical or political concerns. It is only the quality of the writing that counts," Horace Engdahl, the academys permanent secretary, told a news conference. "He is a great writer of novel and drama and a renewer of both genres in the Chinese context but also a writer that has a universal knowledge to offer readers all over the world," Engdahl said. Gao won the prize, worth about 900,000 dollars, for work "of universal validity, bitter insights and linguistic ingenuity, which has opened new paths for the Chinese novel and drama", the academy said in its citation.

Cosmonauts happier than astronauts SAN FRANCISCO, Oct 13: Russian cosmonauts who served aboard the Mir space station were generally happier and more satisfied than their American counterparts, according to the first-ever mental health study of crews and controllers in manned space missions. The study, conducted by University of California-San Francisco researchers, concluded that lopsided crew composition of two Russians and one American on each mission left US astronauts feeling both frustrated and lonely. "In multicultural crews, especially small crews, one has to pay a lot of attention to the culture and language background of the people involved," Nick Kanas, a UCSF Professor of psychiatry, said yesterday. "A single person who is different from the other two can feel isolated." Kanas study, which was conducted under contract to NASA and in conjunction with Russias institute for biomedical problems, surveyed 13 crew members and 58 mission control personnel during NASA missions to Russias Mir space station between 1995 and 1998. It found unequivocally that the American participants were less satisfied with their group interaction and work environment than were the Russians, reporting less support and direction from superiors, more work pressure, less personal opportunity and less physical comfort. Kanas said a major reason for the difference was likely the fact that on each mission, a solitary US astronaut was teamed with two Russian crewmates. "This creates a potential imbalance," Kanas said. "The commander was always a Russian the language used was always Russian and the operational control of the Mir space station was in Russian hands." Kanas, who is also associate chief of mental health services at the San Francisco Veterans Affairs Medical Centre, said that the results of the study should prove useful to NASA as it plans future, lengthy missions - from the international space station to potential missions to Mars. "Any problems that exist are highlighted when you are confined and further highlighted when you are confined for months," Kanas said in an interview. "One of the things were recommending in the future is that crews be alerted to this before they fly ... That there are mechanisms for crew members to look at how they are relating in space." Three-person crews are likely to remain standard for some time, chiefly because the planned space stations soyuz escape pod can hold only three people. Kanas report stressed that care should be taken on future missions to avoid setting up an automatic "odd-man out" situation, which could exacerbate tension among the crew. "Three person crews are tough because the number three, even when everybody is demographically similar, is a very unstable number," Kanas said. "And it always gets more difficult when you go into it with an automatic minority, either by language or culture or sex." Until crews can be expanded, Kanas suggested that officials set up a system whereby the leadership role can be rotated among the three crew members - preventing the formation of onboard power blocs. Kanas said the study also indicated that NASA should strengthen psychological training for astronauts, noting that while most US space missions thus far have been relatively brief, future trips could send astronauts into space for months or even years with no outside support. "On a trip to Mars, for example, there is going to be a time delay in communication, and any sort of medical problem that takes place is going to have to be taken care of by the crew itself," Kanas said. "It is important that at least one of the members, and maybe more, have some therapeutic and psychological counselling training." (REUTERS) |
Arms-type treaty needed to halt tobacco smuggling LONDON, Oct 13: An international treaty to regulate the tobacco trade, similar to controls on the arms business, is the only way to stop cigarette smuggling, experts said in the British Medical Journal today. "We are talking about a substance that kills hundreds of thousands every year, yet in many countries, including Britain, tobacco import and export controls are alarmingly lax," Martin Raw, an honorary senior lecturer at Guys, Kings and St Thomass School of Medicine, London, said in a statement. "That is why we are recommending that tobacco transit should be controlled by mechanisms similar to those used in arms control." Raw and Luk Joossens, a consultant at the International Union against cancer in Brussels, said that around one third of global tobacco exports disappear into the contraband market. They rejected tobacco industry assertions that smuggling occurred because of price differences between countries. Most smuggling was "container fraud" whereby cigarettes were exported duty-free to a country where no real market existed before being smuggled back into their country of origin, or to a third country, avoiding duty, Raw said. "The main smuggling market is containers of cigarettes legally exported from, for example, england to Andorra and then smuggled back into England thus avoiding duty," Raw told Reuters. "The key here is not cross border price differences it is the illegal evasion of duty." In September British media said that tax officials would quiz British tobacco firms about why they exported billions of cigarettes to countries where their brands were rarely smoked. "One of the problems has been that the manufacturers are technically within the law, arguing that what dealers do with their (legally bought and sold) cigarettes is not their business," Raw and Joossens said in the BMJ. Bootlegging, where cigarettes are bought cheaply and then smuggled to countries where they are more expensive, was a minor portion of the global smuggling market, Raw said. Lowering taxes would not halt smuggling. Thus the researchers rejected the idea that lowering taxes, as advocated by the tobacco industry, would prevent smuggling. The tobacco industry holds that lowering taxes in countries where cigarettes were expensive would reduce inequalities in price thus reducing bootleg smuggling. But Raw said Canada had reduced taxes only to find that cigarette consumption increased and tax revenue decreased. Lowering taxes would not have a great effect on container smuggling because profits from tax evasion would still be attractive, Albeit reduced, he added. One example of successful International Cigarette Control was cooperation between authorities in Spain, France, Britain, Ireland and Andorra in 1997 which reduced the illegal cigarette market in Spain from 15 per cent in 1995 to five per cent in 1999. The BMJ report comes as the worlds top cigarette makers and the World Health Organisation face off in Geneva to debate an anti-tobacco pact which is seeking a global ban on tobacco ads, higher taxes and tighter controls on underage smoking. The hearings pit tobacco companies, farmers and smoking groups against medical associations and health campaigners. The WHOs chief Gro Harlem Brundtland has made the fight against smoking a policy priority and aims to establish the worlds first anti-tobacco pact by 2003. (REUTERS) |
South Korean President wins Nobel Peace Prize OSLO, Oct 13: South Korean President Kim Dae-Jung won the Nobel Peace Prize today for his work toward peace and reconciliation with North Korea that led to a groundbreaking summit with his North Korean counterpart. "In the course of South Koreas decades of authoritarian rule, despite repeated threats on his life and long periods in exile , Kim Dae-Jung gradually emerged as his countrys leading spokesman for democracy," according to the citation. South and North Korea, foes on the battlefield a half-century ago, have warmed to each other more in the last few months than in more than a generation. Their armies remain locked in a standoff across a sealed border, but the mood on the peninsula is considerably lighter. After patiently pursuing contacts with North Korea during the first two years of his presidency, Kim traveled to Pyongyang in June to meet with North Korean leader Kim Jong Il. The two countries then stopped propaganda broadcasts, held a reunion of separated families, opened border liaison offices and agreed to reconnect a cross-border railway. "His visit to North Korea gave impetus to a process which has reduced tension between the two countries," the Norwegian Nobe Institute said. "There may now be hope that the cold war will also come to an end in Korea." The announcement was a cliffhanger to the last minute as the speculation was more muted than usual. Last years winner, the Humanitarian Group Doctors Without Borders, figured heavily in guesses ahead of the announcement. The five-member committee and its non-voting secretary Geir Lundestad stake their pride in keeping the secret. (AP) |
