Questions about the afterlife

April 19th 2010 11:38
life after death

A remarkable story has unfolded today about the near-death experience of a three-year-old boy in Germany.

The story has three extraordinary levels. The first is that Paul Eicke, of Berlin, revived three hours and 18 minutes after drowning. The child fell into a pond at his grandfather's house and is thought to have been in it for at least several minutes before he was noticed and pulled from the water.


Efforts to resuscitate him failed. The boy's father gave him heart massage and mouth-to-mouth for 10 minutes until a medical helicopter arrived. The paramedics on board continued resuscitation procedures during a 10-minute flight to hospital, where doctors then took over and tried for "hours" to save the child. Just after they gave up, however, Paul Eicke's heart decided to start beating again.

The second remarkable fact is that it appears Paul will make a full recovery, suffering no brain damage because of the coldness of the water he fell into. His core temperature after being pulled from the pond was measured at 28 degrees, compared to a normal human body level of 37 degrees. It is known that cold temperatures slow the metabolism and allow the body to survive longer without oxygen, but Paul's case is still exceptional. "When children have been underwater for a few minutes they mostly don't make it," said Professor Lothar Schweigerer, director of the clinic to which Paul was taken. "This is a most extraordinary case." That view is supported by an American study which showed that, of children who survive drownings, 92 per cent are found within two minutes of submersion.


The third remarkable aspect of the story surfaced after Paul was well enough to speak — when he was able to tell those around his hospital bed what he had seen and done during the three hours and 18 minutes he was thought to be dead.

Remember, this is the story of a three-year-old, someone unlikely to have woken and recognised the reality TV and sensationalist magazine possibilities.

Paul Eicke told his family, friends and assembled staff that he had been to heaven. And there, he said, he had seen his dead grandmother. "There was a lot of light and I was floating," Paul said. "I came to a gate and saw Grandma Emmi on the other side. She said, 'You go back to your mummy. I'll wait for you here'.''

He added, "Heaven looked nice, but I am glad I am back with mummy and daddy now." Mummy and daddy, no doubt, agree.

Near-death experiences like that described by Paul Eicke are not new. Popular interest in what are commonly termed NDEs was sparked by the book Life After Life, written by Raymond Moody and published in 1975, but NDEs have been studied for many years by people in a variety of fields, including psychology, psychiatry, parapsychology and hospital medicine.

All this leads to an Agence France Presse news story of two weeks ago which said NDEs are reported by between 11 and 23 per cent of survivors of heart attacks. The report used that fact to introduce what could be the fourth extraordinary level of this story. Or, perhaps, it proves that there was nothing extraordinary about the Paul Eicke story, nor about any other NDE.

AFP reported the findings of a study in Slovenia, published in the respected Belgian peer-review journal Critical Care, which investigated 52 heart attack cases, 11 of which reported NDEs. The researchers found no common link in terms of age, gender, education, religion, fear of death, time of recovery or drugs used to resuscitate the patients.

They did find one common link however — high levels of carbon dioxide, and to a lesser degree potassium, in the blood.

Can these things create hallucinatory experiences? Medical science isn't sure. The researchers say further work is needed. But it could be the beginning of the end for notions of premature visits to the afterlife.

Should we abolish daylight saving?

April 4th 2010 20:28
daylight saving

VYOOS EDITORIAL
The debate about daylight saving seems to reappear every six months. Go figure.

In the past week or two, as northern hemisphere citizens go through the annual vexation of losing an hour's sleep, and southern hemisphere citizens enjoy the annual luxury of an extra hour's slumber, an American scientist has called for the abolition of daylight saving because, he claims, it does not achieve what it is supposed to achieve.

Dr Hendrick Wolff headed a team of University of California scientists which studied the effect of daylight saving on energy consumption.

They took advantage of an unusual situation in Indiana where, until 2006, only 15 of its 92 counties swapped to daylight saving. If you wanted to know the time in Indiana, you needed GPS.

From 2006, however, State authorities decided to present a unified clock, all 92 counties switching to daylight saving. This created an opportunity, by comparing energy consumption patterns before and after, to see if daylight saving saved energy.

It didn't. In fact, the study showed power use increased in the counties adopting summer time for the first time in 2006, adding about US$8 million to household electricity bills.

"Daylight saving does not save energy,'' Dr Wolff said. "If society wants to keep daylight saving time we need to have better arguments, as the old energy story doesn't work anymore.''

The old energy story? Dr Wolff's assumption that daylight saving is an energy issue is arguable. It's a lifestyle issue. It's about having an extra hour of daylight in summer to play with the kids in the backyard. Or do some gardening. Or drink beer. It's about the community's deep sense of satisfaction, once a year, when we get an extra hour in bed.

An Australian scientist, Professor Michael Polonsky, of Deakin University, was also perplexed by the Wolff study, suggesting energy conservation was never the aim. It was important to remember, Polonsky said, that air-conditioners were not in widespread use when daylight saving became popular in the 1970s.

It was a social initiative, Prof Polonksy says, and from that perspective, daylight saving had too many benefits to abolish it. "The social phenomenon has been valuable and I think, to get rid of it, would be a hard change,'' he said.

Women as bread winners

March 18th 2010 07:19
vervet monkeys, female dominant

So much for males being the bread winners. According to new research based on monkey responses we may, at a basic and instinctive level, see women as the bread winners.

A team led by biologist Erica van de Waal, from the University of Neuchatel in Switzerland, conducted research amongst wild vervet monkeys in South Africa. The team trained dominant male and female monkeys to teach other monkeys a simple box-opening task. The researchers made a comparative study of the responses to the teachings of the dominant males versus the dominant females.

The monkeys, they found, were far more likely to try, and to succeed in, opening the box if their demonstrator had been a female.

"Females are core group members with higher social status than males, and more knowledge about food resources," van de Waal in the research report, just published in a British Royal Society journal. Male monkeys have a tendency to wander off looking for mates in other groups — the old greener grass over there syndrome — whereas females tend to return to the home group.

The research, van de Waal concluded, revealed valuable insights into "the evolution of traditions and culture in species living in stable groups, including humans".

large hadron collider
The Large Hadron Collider
A woman in Europe has failed to save the world after a court in Germany yesterday dismissed her claim that Earth is likely to be sucked into a black hole if scientists resume testing at the Large Hadron Collider, the world’s largest atom smasher.

The woman, who has not been named, was convinced a resumption of scientific work at the collider, which has had a checkered and controversial history, posed a serious threat to the planet. She was so worried, she took her case to the German Constitutional Court in Karlsruhe

tardigrade water bear

There are creatures indigenous to this planet called tardigrades and they are in the news because it has just been discovered that they can live in space. Outer space. Vacuum territory. The place where, it has previously been believed, the only things that can survive are some of the hardier forms of cosmic dust.
