The number of television sets has dwarfed the number of people in US households in the past two years, according to Nielsen Media Research.
"There are today 2.73 television sets versus 2.55 people in typical US households," said Gary Holmes, spokesman for Nielsen. "Somewhere between 2001 and 2004, the number of TVs outgrew the number of people."
He attributed that trend to the fact that television sets have become more affordable and to increasing diversity in programming.
"With the proliferation of television channels and programs, there is more desire for everyone in the house to have their own TV set," Holmes said.
He said half of US homes have three or more sets today, and a mere 19 per cent have one set. That is compared to 1975 when 57 per cent of households had one TV set and 11 per cent had three or more.
The increase in the number of television sets coincides with an increase in television viewing, which now stands at eight hours and 14 minutes a day per average household, a record high and a three-minute increase from the 2004-05 season.
The average amount of television watched by an individual viewer increased three minutes per day to four hours and 35 minutes, also a record, Nielsen said.
Holmes said another surprising finding was an increase in the amount of time teenagers, particularly girls, spent watching television.

64 Foot Wave
Monster breaks off Tassie
September 22, 2006
SMH
Gale force winds have produced a massive 19.5-metre wave off the coast of Tasmania, according to surf forecasters.
The rogue wave was recorded about 9am (AEST) yesterday and is believed to be one of the largest ever measured in Australia, forecasters say.
Swellnet website forecaster Ben Matson said a waverider buoy located 10 kilometres from Cape Sorell, on Tasmania's west coast, recorded a wave peaking at a height of 19.5 metres (64 foot) as westerly winds crossed the coastline.
"It was probably a combination of several waves that all combined at the one time to produce this single enormous wave," he said.
"Large swells are common in the Southern Ocean at this time of year but wave heights of this magnitude are extremely rare."
Mr Matson said waves of that size had the potential to cause significant damage to ships and had been known to "send oil tankers to the bottom of the ocean" in other parts of the world.
Forecasters were currently examining old data but Mr Matson said the wave could be the largest ever measured in the country.

First penis transplant comes unstuck
Ian Sample in London
September 19, 2006
A CHINESE man who had the world's first penis transplant had the organ removed two weeks later because he and his wife had a "severe psychological problem" with his new penis.
The man's penis was damaged beyond repair in an accident this year, leaving him with a one centimetre-long stump with which he was unable to urinate or have sexual intercourse.
"His quality of life was affected severely," said Dr Weilie Hu, a surgeon at Guangzhou General Hospital.
Doctors spent 15 hours attaching a 10-centimetre penis to the 44-year-old man after the parents of a brain-dead man half his age agreed to donate their son's organ.
The procedure, described in a case study due to appear in the journal European Urology next month, represents a big leap forward in transplant surgery.
After 10 days, tests revealed the organ had a rich blood supply and the man was able to urinate normally. Although the operation was a surgical success, surgeons said they had to remove the penis two weeks later.
"Because of a severe psychological problem of the recipient and his wife, the transplanted penis regretfully had to be cut off," Dr Hu said.
An examination of the organ showed no signs of it being rejected by the body, he said.
Jean-Michel Dubernard, the French surgeon who this year performed the world's first face transplant on a woman who had been attacked by a dog, said psychological factors were a serious issue for many patients receiving certain "allografts", or organs from donors.
"Psychological consequences of hand and face allografts show that it is not so easy to use and see permanently a dead person's hands, nor is it easy to look in a mirror to see a dead person's face," Dr Dubernard wrote in European Urology.
"Clearly, in the Chinese case the failure at a very early stage was first psychological. It involved the recipient's wife and raised many questions."
In 2001, surgeons were forced to amputate the world's first transplanted hand from Clint Hallam, a 50-year-old New Zealander, who said he wanted the "hideous and withered" hand removed because he had become "mentally detached" from it.
Andrew George, a transplant expert at Imperial College London, said: "Doing a penis transplant should be no more complex than anything else. But it takes time for nerve sensations to kick in and it's not clear whether the patient would ever be able to have sex with it."

Energy Polariser
ANDREW DENTON: I will move on to what was the low point in your career, which was the Energy Polarizer, which you brought out in the...
PETER BROCK: Yeah, that was an interesting thing, actually, because...
ANDREW DENTON: Can I just explain to those that don't know what it was, it was just a, it was a box...with magnets and crystals, which you said would turn even a dog of a car into a sweet-running one. And basically, the press turned on you as some kind of New-Age crank.
PETER BROCK: They did, but I must tell you that the only portion of crystal in that was a sliver of crystal, not unlike what you have in a wristwatch. So I wasn't exactly, you know, sleeping under pyramids and stuff like that.
ANDREW DENTON: Why did they turn on you?
PETER BROCK: I didn't have the ability to give them a suitable explanation as to why it worked.
ANDREW DENTON: And why not?
PETER BROCK: Too difficult, really. I mean, it was gonna cost me 750,000 dollars to get a scientific validation of it. And I didn't have it. I said, "Look, can you just trust the fact that it does work?" And most of the journalists said, "Yeah, this works good."

Fish aren't thick: scientist
David Braithwaite
September 12, 2006 SMH
Fish can be trained en masse and then used to train other fish
Watch this space ... "It's completely ridiculous that an animal could survive without a memory," says Dr Brown.
Having a memory like a goldfish could actually be a good thing, says a Sydney scientist who has spent 10 years proving fish are not as dumb as we think.
Fish are not the bowl-circling dimwits we imagine and could be as socially able as monkeys and elephants, Dr Culum Brown of Macquarie University says.
The biology lecturer has spent the past decade putting fish through learning and memory tests, which he says shows they are much deeper thinkers than they look.
For a start, Dr Brown says the three-second memory of goldfish is a myth: "It's completely ridiculous that an animal could survive without a memory."
Fish are so clever, Dr Brown says, that those schooled in survival skills can even teach their captivity-raised peers how to get by in the sea.
To help prove his theories, Dr Brown put rainbow fish into a tank with a mock trawler net with a single hole and watched how long it took them to find an escape route.
"Without any prior experience the fish learned where the hole was in about five runs," he says.
A year later, the same fish managed to find the hole on their first try, which Dr Brown says shows they easily recalled the skills they had learned.
In another study, Dr Brown scared intertidal gobies from a rock pool and as they dived for safety found they plopped precisely in surrounding pools.
"This suggests that fish are able to form mental maps similar to those people use when planning a route to a familiar destination," he says.
Dr Brown also studies "social learning" among fish, where fish trained to recognise predators and wild food teach captivity-bred fish how to survive.
"Fish can be trained en masse and then used to train other fish," he says.
"What we've found is the latter groups of fish learn more rapidly when ... placed with trained fish."
The research could prove useful to the aquaculture industry, Dr Brown says.

Poor twice as likely to commit suicide
Julie Robotham Medical Editor
September 11, 2006
SMH
YOUNG adults from disadvantaged backgrounds are almost twice as likely to commit suicide as their more affluent peers, new research has found.
Despite overall reductions in suicides, the proportion of people from low socio-economic groups who took their lives between 1999 and 2003 rose more steeply than at any other period in the previous three decades, analysis by Richard Taylor, professor of population health at the University of Queensland, found.
"These aren't individual phenomena, these are group phenomena," Professor Taylor said.
"We've got to get beyond the psychiatric model … depression is not an answer. Depression is a question. We have got to look harder at what are the social and economic underpinnings of risk."
Suicide rates peaked in the late 1990s, when the wider use of anti-depressants and the introduction of a National Suicide Prevention Strategy began to turn around an increase that had persisted since the 1970s.
But Professor Taylor said these measures had been insufficient to save the lives of people lower down the income and education scales, who were increasingly priced out of the housing market and denied secure employment.
It was also possible that poorer people had less access to specialist mental health services and medications for their mood disorder and that mental health campaigns might be bypassing the most vulnerable people because their messages were "made by the middle class for the middle class".
Professor Taylor found suicides among 20- to 34-year-old men in the most disadvantaged one-fifth of the population had risen by 8 per cent in the five years from 1999 to 2003, compared with the preceding period, to 48.6 suicide deaths for every 100,000 people. That was nearly double the 27 per 100,000 of young men from the most affluent one-fifth of backgrounds, whose suicide rate fell by 15 per cent over the same period.
The analysis, published this week in the journal Social Psychiatry and Psychiatric Epidemiology, applied Australian Bureau of Statistics rankings of the relative socioeconomic status of small geographic areas to the addresses of people who had died by suicide.

Generation Y's crime of their lives
Matthew Moore
September 11, 2006
SMH
ONE IN seven men born in NSW in 1984 had a criminal record by the time they turned 21, the first study of the proportion of generation Y members charged with a crime has found.
The study of all 81,784 people born in the state that year shows that 9.9 per cent of them were brought before a court before they turned 21, and virtually all of that 9.9 per cent were convicted of at least one offence.
About a third of these convictions were for drink-driving and other motor vehicle offences, 13 per cent were for theft and 10 per cent were for "acts intended to cause injury".
The study by NSW Bureau of Crime Statistics reveals that one in 200 people born in 1984 was sentenced to jail before their 21st birthday.
The director of the bureau, Don Weatherburn, said he was surprised such a big proportion of people had criminal records.
"It gives the lie to the proposition that criminals represent some tiny fraction of the community," he said.
As this study was the first of its type, Dr Weatherburn said he could not say whether the proportion of people with criminal records was likely to be different for people born in other years.
One brush with the law was enough for most, as 61 per cent of those who had records had only one appearance before the courts.
Seventy-two per cent of people who appeared before the courts did so after they turned 18.
A small number of people were responsible for a large number of court appearances: 9 per cent of the 9.9 per cent brought before a court appeared in court five times or more before they turned 21 and 2.3 per cent appeared in court 10 times or more.
As most people only offended once, Dr Weatherburn said, it was pointless "coming down hard" on them. He said resources should be allocated to the small group who committed most of the offences, because there were "enormous potential savings".

WHO concerned by drug resistant strain of TB
The World Today - Thursday, 7 September , 2006
Reporter: Zoe Daniel
ELEANOR HALL: The World Health Organisation has released alarming findings about new strains of the disease tuberculosis, which it says are almost untreatable.In most Western countries TB is virtually non-existent but it's still highly prevalent in the third world. These virulent new strains have already infected people in the United States and Eastern Europe.And experts are meeting in South Africa to deal with a serious outbreak in the province of Kwa Zulu Natal, as Africa Correspondent Zoe Daniel reports.
ZOE DANIEL: It's feared that the Extreme Drug Resistant strain of TB was created by inappropriate use of TB medications. It's believed that TB resistance can be created by the use of drugs at the wrong dosage or for the wrong period of time.
Dr Paul Nunn from the World Health Organisation says the increasing prevalence of the drug resistant strain is a huge concern to health authorities.
PAUL NUNN: Well, the World Health Organisation is concerned because it's virtually or definitely untreatable. By definition this extreme drug resistance or XDR, as it's increasingly be called, is resistant to at least three of the six groups of second line drugs that are available. And by definition they're already resistant to the first line drugs. And so this means that any patient with XDR TB cannot get optimal treatment because we recommend that a patient with tuberculosis be treated with at least four drugs.
ZOE DANIEL: In South Africa an outbreak of drug resistant TB in Kwa Zulu Natal illustrates the extent of the problem. South Africa has the highest rate of HIV in the world, and tuberculosis is notorious for attacking the weakened immune systems of those who are HIV positive.However there was no treatment available when the drug resistant strain took hold, and the result for most was death.
PAUL NUNN: We carried out a survey that was published earlier this year showing the problem exists in about two per cent of cases globally. But what's most worrying is an outbreak recently reported from Kwa Zulu Natal showing that the XDR is there. That of the 53 patients that they looked at, 52 died within 210 days. So this is an extraordinarily high mortality rate. And clearly this is linked to the fact that all those tested were HIV infected as well. And this is the problem that we're really worried about. It's the spectre of extreme drug resistance fuelled by HIV in countries that don't really have the resources to address it right now.
ZOE DANIEL: At the moment TB causes about 1.7 million deaths per year around the world. But that's with the cocktail of drugs commonly used to treat it. Now resistance is showing up to the usual front line drugs and many of the so-called second line drugs that are used when the frontline drugs don't work.Dr Paul Nunn says part of the problem is that new drugs aren't coming onto the market because TB isn't present in most Western countries.
PAUL NUNN: During the 1980s and 1990s research into new anti-TB agents virtually disappeared in pharmaceutical companies because the TB problem was felt to be solved in the north and people did not realise the scale of the TB problem in developing countries at that time. And only in the last six or seven years has research really ramped up for new anti TB agents.The global alliance for anti TB drug development leading the fray, if you like, in New York funded largely by the Bill and Melinda Gates foundation. But clearly more investment in that area is required.
ZOE DANIEL: It's not yet clear how easily the drug resistant strain of TB is transmitted.

Yin and Yang
From Wikipedia
Taijitu, the traditional symbol representing the forces of Yin and Yang
The concepts of yin and yang originate in ancient Chinese philosophy and metaphysics, which describes two primal opposing but complementary forces found in all things in the universe.
Yin, is sad, the darker element, is passive, dark, feminine, downward-seeking, and corresponds to the night;
Yang, is happy, the brighter element, is active, light, masculine, upward-seeking and corresponds to the day;
Yin is often symbolized by water, while Yang is symbolized by fire.
The pair probably goes back to ancient agrarian religion; it exists in Confucianism, and it is prominent in Taoism.
Though the words yin and yang only appear once in theTeo Te Ching, the book is laden with examples and clarifications of the concept of mutual arising.
The concept is a fundamental principle of Traditional Chinese Medicine.
Yin and yang are descriptions of complementary opposites rather than absolutes.
Any yin/yang dichotomy can be seen as its opposite when viewed from another perspective.

"Crikey" - Steve Irwin killed by stingray
Crocodile man reported dead
September 4, 2006
Television personality and environmentalist Steve Irwin has died in a marine accident in north Queensland, state government sources say.
The 44-year-old is believed to have been killed by a stingray barb that went through his chest, the sources said.
He was filming an underwater documentary off Port Douglas when the accident occurred.
Mr Irwin's body was being flown to Cairns by helicopter.
Australian emergency officials could not immediately confirm the reports.
Irwin won a global following for his daredevil antics but also triggered outrage in 2004 by holding his then one-month-old baby while feeding a snapping crocodile at his Australian zoo.
It is believed his American-born wife Terri is trekking on Cradle Mountain in Tasmania.
Mr Irwin - known worldwide as the Crocodile Hunter - is famous for his enthusiasm for wildlife and his catchcry "Crikey!''.
The father of two's Crocodile Hunter program was first broadcast in 1992 and has been shown around the world on cable network Discovery.

Left or Right Pawed ???
Richard Macey
September 1, 2006
SMH
YOUR dog is inquisitive and loves exploring the neighbourhood. Or he is timid, nervous, and prefers sticking nearer to home.
His behaviour could be linked to his being left- or right-pawed.
And before you punt your wages on the next race at Randwick, it might be handy to know whether the horse, thanks to being left- or right-hoofed, prefers galloping clockwise, as they do in NSW, or anti-clockwise, as in Victoria.
There is growing evidence, says Paul McGreevy, a senior lecturer in the University of Sydney's Faculty of Veterinary Science, that behavioural traits in many animals, including dogs and horses, are linked to their handedness, or "laterality".
That animals have a preferred side has been accepted for almost 20 years. Now Dr McGreevy is conducting a three-year study, funded by the Australian Research Council, to explore "pawedness" in dogs.
His students have tested 270, giving them food cylinders and watching which paw they use to hold them steady. Repeating the experiment 100 times on each dog, they found about 15 per cent are left-pawed, 15 per cent right-pawed, and the rest are neither.
"Dogs that lack any bias are more likely to have noise phobias," Dr McGreevy said. "They get upset by thunderstorms and fireworks. If we can show laterality is a predictor of a dog's motivation or reluctance to explore, we can help guide dog and sniffer dog trainers select the right animals."
Knowing which side of a dog's brain is dominant could change pet training.
"There is a convention to train dogs on the left of the trainer. It's a human convention we have imposed, and it's unlikely to suit all dogs equally."
There appeared to be no differences in pawedness between breeds, but "males are more likely to be left than right, and females more likely to be right than left".
He has also confirmed "hoofedness" in racing horses. After watching 186 grazing in paddocks, observing whether they put their left or right hoofs forward as they ate, he found 40 per cent had a left preference, while 10 per cent had a right bias. The rest had none.
A horse might develop more powerful muscles on, for example, its right side, as a result of its hoofedness. It might thus excel on right curving tracks, but be disadvantaged going anti-clockwise.
That animals share the human trait of being left- or right-handed should not be surprising.
"It's evidence we all came from a common ancestor."

YOUR dog is inquisitive and loves exploring the neighbourhood. Or he is timid, nervous, and prefers sticking nearer to home.
His behaviour could be linked to his being left- or right-pawed.
