According to new research humans purposefully set out to reach Australia. It seems scientists can read minds now - what a great leap forward! Seriously though, knowing what individuals are thinking is an impossible thing to do, largely because people perceive settings differently. No two people are exactly alike not even twins. Perception is a function of consciousness as perceived through the senses which differs for everyone. Sea levels were lower in 65,000 BP, so islands off the coast of northern Australia could be seen from high points on islands off Indonesia. There is a problem here, however, in that there are major racial differences between Australian Aboriginals and Indonesians. Surely, some dark skinned inhabitants of the South East Asian archipelago would have remained and interbred with "typical" Asians we see today. Note, Papua New Guineans are different than Australian "natives". To say that an assembly of about 100 boats were organized...

Why does your skin shrivel up when you stay in the bath too long? you would think that science would have solved this mystery long ago, but this is not the case. There has been a breakthrough though. German scientists have found the mechanism that makes skin go all crinkly then return to its normal state. This could have an impact on materials used by Mankind in the future. Our wonderful Internet world means that every new discovery is advanced by someone or some institution. Now let's get back to wrinkly skin. The outer layer of skin is composed of keratin protein filaments. This quickly absorbs water when you get into the bath. It is created in a matrix system of interlaced fibers. Thus producing counteracting pressure that pushes the water out when you get out of the water..  There we have it - simple wasn't it? It is amazing how science and discovery go parallel with each other. The reason for wrinkly skin was discovered when elastic woven fiber made b...

Australians are so obsessed about staying out of the sun to prevent skin cancer that the number of people getting osteoporosis is increasing. This is a sad consequence of a positive behavior change. Osteoporosis would not be a problem if more people took calcium tablets with vitamin D each day. Unfortunately, many would rather spend their money on other things. The disease affects young people as well as the elderly. The Nepean Consensus Statement meeting has been praised for making the disease more widely known. However, money spent on such activities is wasted, considering you can treat yourself without actually being diagnosed with the disease. Developing "fancy" management practises is unnecessary. Giving calcium and vitamin D to the elderly who already suffer with osteoporosis is a waste of time, because once you have the disease it cannot be cured. A person need not adopt a calcium rich diet: calcium and vitamin D in tablet form are easily absorbed by the body. Eve...

Long-necked dinosaurs had hollow bones in their skin according to fossils in Madagascar. The animal in question is the giant Rapetosaurus. Hollow bones are found in the skin of reptiles and a few mammals. These skin bones are called osteoderm. Dinosaurs with hollow skin bones are Titanosaura, a Sauropod, Rapetosaurus, Stegosaurus and Ankylosaurus. It is believed that the bones stored mineral for hard times. Rapetosaurus, for example, had only a few bones spread throughout their skin, so the bones were not used for defence or to moderate temperature. The fossils in Madagascar were of Rapetosaurus. What applies for Rapetosaurus can be used to evaluate the hollow bones of other dinosaurs. It cannot be ruled out that Titanosaura used the bones partially for defence but the main function of hollow bones was to store minerals. http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspot.com/ http://www.feeds.feedburner.com/AdventureAustralia http://www.technorati.com/...

Australian green tree frogs live in the dry desert without dehydrating. This has been a mystery - until now. They move from a cool night into warm burrows. Then they "mist-up". They sit in the cold air for hours until they can hardly move. There is a good reason for this. It has been discovered that their skin "takes-on" water. Inside the burrows water is in the air due to the warmth. Droplets form on their cold skin by condensation. A group of tree frogs frequented a hollow tree in the dry outback. Researchers caught some frogs, cooled them in the cold night air, lowered them into the log in a cage for a quarter of an hour, Then tested them. The frogs gained 0.4 grams in weight, their bodies glistening with water droplets. It is now believed that lizards and spiders also use this technique to get water. Earlier work in the laboratory indicates this. Just a little water is enough to survive. http://www.adventure--australia.blogspot.com/ http://www.ty...

Scientists are looking to moles to enable Mankind to live longer. No, these are not the animal kind of moles. They are the moles one has on one's body - beauty moles. Rather than saying "Yuk, cover that up", we should be saying "You lucky thing." It seems people with moles have benefits that others do not have. The bones in these lucky ones are, apparently, stronger than usual. It is also claimed that they have less wrinkles making them look up to a decade younger than "non-molers". The Heart, eyes and muscles are stronger as well. The downside is the increased risk of skin cancer. Just live like Count Dracula, stay out of the light, and you should be laughing. Researchers are working on a way to turn moles off so they become less visible. This is good if you have the genes for moles, but what about the rest of us? There is no way we can get the benefits from moles which make the telomeres of white blood cells longer, thus slowing bone deterioration an...
