Science Says Jellyfish Do Not Grow a Backbone - Spineless

Jellyfish could be real-world monsters out to take over the planet. They readily breed in their millions. Many have taken up residence under buildings constructed by Man off the shoreline.

Mysterious Death

The odd case of a woman who police claim stabbed herself to death with an 8 inch long knife - you would have to be a Japanese officer in dire straits to do this! For some reason police have always stuck to their suicide finding. A doctor working in a funeral parlor thought it was odd that the woman had wounds on her hands as if she was defending herself. It took two years before police got back to him after he reported this.
Dr Karen Mahlo
Police said that the victim, Dr Karen Mahlo, had stabbed herself as she lay on her back in bed. John Michael Hehir, her boyfriend, was not a suspect, then: his claims of not being able to phone her and rushing to her house had been verified. He said lights were turned off downstairs. Why would you turn the lights off if you were going upstairs to kill yourself?

A very strange thing was that the knife had been plunged through her pyjamas. One would have pushed the pyjamas aside to get it over with. Her death was well planned: a note was on a running computer with a copy on the desk and another addressed to her children telling then they were left nothing. Cases of such vigorous preparation are rare.

John Hehir behaved in a peculiar manner. During the drive to Mahlo's home on the night of her death he phoned for an ambulance before he reached the house. Soon after he returned, then took a bike and a USB drive. Hehir had a will in his possession which left him her house but not her investment properties. The "real" will was located on the computer leaving everything to her children and parents. Unfortunately, the computer will is not valid.

Justice Philip McMurdo dismissed the family's claim. There has never been an inquest into the death. It shows how stupid police and judges are in cases like this. John Michael Hehir has never been charged.

Whale Culture in Japan

Japan plans to resume whaling in the Antarctic next year. It will modify its "scientific"research system to fit in to what the International Court of Justice (ICJ) wants, although the court stated that scientific whaling per se was illegal and would always be illegal.

Japan's Institute of Cetacean Research (ICR) says it will take the Sea Shepherd Conservation Society (SSCS) to the ICJ to stop it harassing Japanese whaling ships when they carry out future legal scientific whale hunting in the Antarctic, in short the resumption of killing of whales for food.

Just why Japan is so pig-headed about continuing to wastefully kill whales says something about Japanese culture - they are arrogant.  Japanese consumers want whaling despite not actually buying whale meat. This nation has tonnes of whale meat in storage because it doesn't sell, despite being highly subsidized.

I am about to get personal about this issue. Those readers easily offended should stop reading now..........

Cultures do not change suddenly. It takes centuries for societies to change. The way people think and what they believe in continue, even though rational circumstance prove that things cannot possibly be as people believe.

Because a war ended and countries apparently got back to normal didn't mean societies changed their ways. Japanese culture is the same today as it was in the 1930s. Arrogance prevails despite bowing to this, bowing to that. This bowing custom came about because Japanese were terrified of samurai - frightened of losing a head or half body.

The truth of the matter is that Japan will continue to hunt whales because of the silly custom of saving-face. They perceive a court order as a blemish on their character. People of other countries do not see it this way at all.

Ten End of the World Is Not Nigh!

Times have always been bad. Before this enlightened age a person could be "bludgeoned" to pieces at random by a man wielding a massively heavy and crude sword. Murder was seldom punished. The law was mainly aimed at theft, settling property disputes, heresy against the church or a challenge to the crown.

Even before Christ people were claiming that the end of the world was nigh. The fiasco about the Mayan calendar shows how such "precognition" can be totally wrong. Once again the recent "clash" of a meteor and asteroid with Earth has drawn the doomsayers out of the woodwork.

Wonders in the heavens have occurred since man came down from the trees. It is not something that stops, then starts again. The lightning strike at St. Peter's Basilica after the Pope announced he would step down was just coincidence. Lightning strikes happen regularly and despite the myth it does strike twice in the same place.

Rabbi Jonathan Cahn says he was inundated with communications asking if the world was coming to an end. Cahn himself is a supporter of the end of the world scenario declaring people are renouncing religion, and there is more sin and immorality.

Sex is not in itself sin. It is a normal human and animal function to beget offspring and continue the species. It is words from angry people that make is appear dirty and sinful. The Catholic Church in particular is responsible for this. Celibacy is unnatural, No other animal does it. It should be noted that homosexuality is practised by other animals: apes and dolphins are examples. Personally, I am not in favor of same sex marriage, but if the majority want it then I will accept it.

People tend to see only what they want to see. It is a fact that a Holy War is going on in the world at the moment. There are no stories in the press about this directly. The war in Alfghanistan and terrorism are mentioned. No one, even organized religion will tackle this issue. It is assumed that maybe it will go away. However, this war will go on for decades. The only real solution is for one religion to win. That, of course, will not happen. Perhaps a new prophet will arise who will dramatically change entrenched views and values. Hope does reign eternal - not much else does!

Albert Einstein's Genius Was Due to His Unusual Brain

Albert Einstein wasn't only a genius her was a very odd human being. His brain shows peculiar differences from the norm; it had many more folds than the average person. This gave the brain a greater surface area. It is like using a larger computer to do calculations.

Upon his father's death in 1955, Thomas Einstein gave the pathologist permission to preserve the brain of Albert Einstein. It was photographed then dissected into 2,000 ultra-thin slices. The slices and slides of them were later distributed to researchers.

The brain had more neurons and glia cells, well outside of the normal range; pariental lobes were unusual in the pattern of ridges and grooves. Einstein only had a brain of average size. The area controlling the tongue and face was larger, as was the region that involves attention and planning. Overall, Einstein's brain was complex. Many people think in words. He said his thinking was like a physical activity.

If selection based on "healthy" genes had been practised Einstein would never have been born. The same could be said for other great people. Sir Winston Churchill, for example, led an odd life. He would drink whisky in the evening right into the early hours and seldom got out of bed before midday.

Marine Animals Die With Unusual Warming off the Coast of Peru

Something is going on out there. Mysterious deaths of particular species of animals occur regularly. Recently dolphins died in their hundreds while thousands of pelicans died off the coast of Lima, Peru. This was followed by thousands of crustaceans dying.

The crustacean affected is red krill. It is known that some species of dolphin eat this food. Pelicans also surface feed for krill.  Why would a food source die after poisoning other animals?

These deaths are not being caused directly by humans with perhaps chemicals or pesticides. The reason is the ocean off the coast of Lima is warming up. Krill have been moving closer to the coast to avoid the heat. Environmentalists blame offshore oil exploration. The government says they died of natural causes, but the seemingly static La Niña with cool weather in the western Pacific (oddly currently warm in the east) is not natural.

Death Adders Are Causing Their Own Extinction

Australia's death adder is contributing to its own extinction. Moving around to hunt their prey is not their method. An adder tempts its victims by laying in ambush and wiggling its tail tip. By wiggling its tail, however, it is noticed by cane toads, frogs and lizards who eagerly gulp down the tasty meal.

After cane toads were introduced into Australia death adder numbers plummeted. Ironically as the cane toad attacks the snake it is bitten, so after its meal the cane toad dies - mutual suicide. Even if the snake eats the toad it will end up dead because cane toads are poisonous.

For millions of years death adders have survived by enticing their prey within easy reach. Now this behavior is leading to their demise. Man cannot intervene to prevent this. There is nothing that can be done.

Danger of Heart Attack After Losing a Spouse

It seems people don't live on after their partner passes away. There is a higher risk of survivors getting a heart attack in the months after losing a husband or wife. It is believed to be due to the increased heart rate from the loss. If the living partner can get through the danger period the risk dissipates.

This shows that people who lose partners need medical help and support from friends and relatives during the grieving process. Doctors should pay special attention to cardiac symptoms. Persistent stress and depression should also be monitored.

The research involved people aged from 33 to 91, so this tendency affects spouses of any age. Subjects wore 24 hour monitors. Heart rate was closely observed. Periods of rapid heart beat occurred during the grieving period. Overall heart rate was also higher compared to people who had not had a loss.

Depression was four time higher than the norm in subjects. This persisted for several years.
