Jellyfish are spineless little devils. I do mean that in a good way. They are the most efficient swimmers on Earth, pulling their way forward rather than pushing. The "immortal jellyfish" rises phoenix-like from the dead. When it dies the decomposing body puts out stolon stalks which become babies. They are rapidly increasing in the world's oceans due mainly to Man. Most variations breed under man-made marine structures such as piers. The killing off of predatory fish for human food allows the transparent creatures to vastly increase in number. Cyaneidae have caused many problems over the years. Those going for a swim regularly get stung. In 2006 the seemingly invulnerable USS Ronald Reagan was put out of action by masses of jellyfish clogging the cooling system. Power plants and desalination facilities have also been stalled. Two million workers became unemployed when the comb jelly native to North America invaded the Black Sea in 1980 and destroyed anchovy...

Is coffee good or bad? People in many countries drink gallons of the stuff, particularly the United States, Italy and South American nations. It has always been said that a couple of cups a day is okay. However, people drink much more than this. Tea drinkers hide behind the myth that tea is harmless while coffee is not. The main "drug" in both tea and coffee is caffeine. It should be noted that professional athletes can now consume as much caffeine as they wish with no fear of getting banned from athletics. This decision was made largely because policing of it was costly and a burden for administrators, not because it does not stimulate the body to improved performance. Apparently drinking a maximum of five cups of coffee a day increases your lifespan - in Japan. Pity other countries failed to find any connection between the two factors. Japan has also claimed resistance against Alzheimer's, melanoma, diabetes and other ailments. Proof elsewhere is weak for this...

We are far too complacent about drug taking, assuming that we can just stop at any time. With alcohol use it is clear that this is not the case. Road breath tests frequently find no alcohol in a driver's system, but a drug test shows up positive. It seem that drugs can be substituted for alcohol. So it is wise not to take any drugs even as an experiment. Drug addiction is not rare for the number of drug takers out there. Many think they can stop. They cannot. Even taking drugs regularly in the short term means withdrawal with occur. Furthermore, there is no know real cure apart from complete abstinence. Not much is written about the health risks from drug taking. Many believe that smoking cannabis is completely safe. However, all the problems of smoking tobacco are possible.  All illicit drugs destroy the body.  Drugs are poison, just like alcohol.  Take them at your peril. Another real issue is permanent damage in brain functioning that can aff...

Millions of dollars is being spent in HIV research.  It is mainly spread by sexual contact. However, venereal diseases in general are being forgotten. Antibiotics are becoming ineffective in combating venereal diseases. Such infections have been around for thousands of years and there is still no cure. Antibiotics used to "knock it on the head" in the past. This luxury no longer exists. A serious resistant strain of gonorrhoea is extant in Australia and New Zealand. It has now arrived on our doorstep. A8806 is very similar to H041 which is absolutely untreatable. Different resistant strains have appeared in Japan, the US and Norway. Because people today are more promiscuous than ever "the clap" is spreading extremely fast. The disease affects the whole body invading mucous membranes such as the sexual organs, eyes and throat. Arthritis, heart infections and meningitis can result. Most people have serious symptoms. Pain when urinating, bl...

It never fails to amaze me how new things are discovered on our doorstep when the majority of people think everything is known about nature.  This is particularly true in Australia where a low number of people live on a vast continent.  Some places have not even been visited by humans for thousands of years. Dr Lisa-Ann Gershwin has identified two species of jellyfish that can carry Irukandji syndrome.  The new species are Keesingia gigas and Malo bella .  Doctor Gershwin works for CSIRO.  There are now 16 species that can cause Irukandji. Keesingia can grow to 50 cm in bell height.  This is by far the largest jellyfish.  Juvenile leatherjacket fish safely live in its subumbrellar cavity as with the more common medusas. The two newly documented species have been generally known for some time.  However, they have not been found in Australian waters before.  They could have been present for a long time or maybe they are new, moving h...

There isn't much doubt that there is discrimination against older members of society. This is confirmed by comments from young people that it is unfair that the elderly usually fully own their own homes.  If the young had their way property would be forcibly taken from seniors. It is forgotten however that the elderly took a lifetime to buy their homes. Another issue is the overreaction to car accidents involving senior drivers. A five year inquiry is going on at present to set a test for doctors to apply to the elderly who want to continue to drive. This is despite the fact that younger drivers have far more car accidents than older people. Young drivers are more dangerous on the following factors: 1) Poor Hazard Detection; 2) Low Risk Perception; 3) Higher Risk Taking; 4) Not Wearing Seat Belts; 5) Lack of Skill; 6) Taking Alcohol and Drugs; 7) More Crashes When Carrying Passengers; and 8) Accidents After 9:00 pm. Let's wish the Monash University inquiry good luck in it...

Western Australia reacted to attacks by dogs on children. A few years ago legislation was passed to not only muzzle but also sterilize American Pit Bulls, Mastiffs and Japaneses Tosas. Since then there has not been a major decline in the numbers of these breeds. The legislation has not worked out as intended. President of the RSPCA, Hugh Wirth, says breeding of "dangerous" dogs has gone underground. Dr Kersti Seksei of the Australian Veterinary Association (AVA) makes the point that dogs of any breed can and do bite people. It is usually the case that household pets bite members of the family. The AVA suggests testing of dog temperament when they are sold. This would be difficult to police because most cross breed puppies are sold privately. Dogs follow their owners' behavior. Dangerous dogs are created, not born. That is why police dogs are always muzzled in public: they are trained to be dangerous. http://www.adventure--australia.blogspot.com/ http://www.tysaus...

Be careful what you put on your skin - the skin absorbs chemicals on its surface. In other words your body consumes and ingests things like soap and toxins in engine oil, etc. Little research is done on this serious issue. In New Zealand a dangerous chemical which lowers IQ in children has been found in sunscreens. It is as damaging as lead paint. Even spraying the chemical into the air where is can be breathed in and ingested can lower IQ. Piperonyl butoxide is also present in insect spray. Cancer Society products even contain the substance. Low vitamin D has been blamed for many diseases when in fact it could be trace chemical in commonly used household goods. If vitamin D deficiency is causal then people in temperate countries would have higher cancer, Alzheimer's, heart disease, autism, depression and ADHD than those in tropical regions. This is only true for some of these illnesses. Too say 31 per cent of Australians in this hot country are deficient is ridiculous. h...

Why bother to be hygienic. We can feed cattle all sorts of filthy stuff, and when we eat it we still remain fit and healthy. This is the message being sent by the president of company Bioniche. In order to promote his new product the president is making dramatic claims. Cattle can all be vaccinated against e.coli, can eat anything and wander around in rubbish, apparently. Such is Mr Rick Culbert's faith in the success rate of his product. The e.coli "bug" lives in all of us both humans and animals. Only dangerous species make us sick. This vaccine will kill all e.coli in the body. Wait a minute! Don't antibiotics kill useful flora in the gut, so we must not take them regularly? What happens to a cow with no e.coli in its system is unknown. Eating such "clean" meat could be dangerous to our health. Outbreaks of food poisoning occur in every country. The fight for cleanliness in food handling must continue. If beef is guaranteed free of e.coli wo...

If you thought smoking cannabis had no health dangers and was safer than smoking cigarettes, you would be wrong. The smoke from both have similar harmful gaseous and particulate chemicals. Smoking cannabis is more dangerous than smoking cigarettes. This is due to the way people behave when inhaling. They try to keep the smoke in the lungs as long as possible in order to get the greatest euphoric effect. Indeed, inhaling smoke from cannabis causes changes in the lungs consistent with bronchitis. Cellular dysplasia indicates malignancy could be the end result. Users believe lung cancer is solely due to smoking tobacco, but a cough and morning sputum production show cannabis use can lead to cancer. Cannabis smoking is addictive and damages your health. Combining this pastime with cigarette smoking is doubly dangerous. http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspot.com/ http://www.feeds.feedburner.com/AdventureAustralia http://www.technorati.com/b...

Though widely accepted in law courts it is well known that witness evidence is suspect.  Even victims in many cases get it wrong.  A querk in humans beings is the ability to identify members of one's own race, for the most part, but the noticable inability to recognize people of other races.  The phrase "you all look alike" is relevant here. What people see can be distorted by a felon carrying a weapon.  Human perception is still based on how our ancestors saw danger.  An opponent carrying a weapon was more dangerous so was perceived as being big and strong. A current study shows that a witness describing someone with a gun said the gun carrier was larger and taller than he/she actually was.  This brings into question prevailing theories on memory.  Could a person be seen as being bigger if more aggression was shown without a weapon? http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspot.com/ http://www.feeds.feedburner.com...
