It seems we can study what animals looked like even though they are extinct. Australian and New Zealand scientists are studying prehistoric feathers to find out what birds were like. DNA has been obtained from the extinct Moa bird of New Zealand from feathers 2,500 years old. Moa are thought to have been still alive 1200 years ago It was 8 feet tall and could not fly. Material has been gleaned from three types of Moa: the stout legged; the heavy footed; and the upland Moa. Somehow they have worked out that wing feathers had speckled white tips. This was to camouflage the bird from predators. The very large Haast eagle once existed that preyed on them. It is claimed that because the plumage of other flightless NZ birds is dull with speckled tips this idea is valid. The scientists plan to get feathers from the end of the quill and further down the quill to compare coloration. It is hoped the findings will enable researchers to correctly reconstruct life-like models of extinct birds. h

The medical community has just noticed a fact that many have known for years - Waiting a long time for an operation can lead to opioid addiction. It is easy to get opiates from GPs just by telling them that you are in excruciating pain and an operation is a long way off. Shane Jackson president of the Tasmanian Pharmaceutical Society says money should be spent on more pain management specialist. This is a waste considering they only tell patients to take paracetamol that does not stop strong pain. Setting up a data base will only lead to patients being denied opiates so they experience more pain and suffering. Blame the patients has always been easy to do. A data base will stop people getting morphine derivatives from all GPs. This creates an added problem. The solution is more medical staff and facilities to do more operations. Reducing the risk of opiate addiction can be solved by denying patients access to such drugs, Though they may turn up in the hospital emergency departme

Treatment for heart disease is advancing at a rapid pace. Soon, a tiny piece of artery will be removed from a patient and a new heart conduit will be formed. This is for minor problems in the heart, less that 5mm wide. Conduits are also being made from synthetic materials. Toleration of foreign substances is not a problems because it degrades quickly. They are used to go over the outside of a graft to stop bleeding. The synthetic conduits are made of a fine poly-(glycerol sebacate) net coated with polycaprolactone and the anticoagulant heparin. Mesh holes are too small for blood to pass through. Nothing of the implant remains after three months. A new structure of endogenous cells with M2 macrophages (which reduces inflammation) remains. Though tests have only been done on rats, use in humans will probably be just as successful. Large grafts using the material will be done to see if this is feasible. This will be a welcome advance in medicine. A graft made of the body's

Sheep are not entirely "group" animals. They can be selfish. Each sheep seeks to get to the middle of the pack. The center of the flock is safest from predators. Individual sheep do not care about those on the outside being taken by wolves, for example. Flock behavior has been analysed. The group moves forward as individuals move away from the sheepdog to the center of the group. Flocks are not homogeneous. Sheep continue to struggle to get to the center as the flock as a whole moves. It is now believed that many wild group animals behave in this way. Wildebeests moving away from lions probably act in a similar manner. Pigeons, crabs and seals have been observed acting selfishly. Now the theory is proved. GPS tracking devices were attached to 46 sheep. Then an Australian Kelpie sheep dog took control of the flock. By monitoring sheep movement every second, the belief became solid fact. Sheep either move in a line from the sheep dog to the center of the flock, sca

We are obsessed with the oil crisis. So much so that we fail to see other problems that face us in the near future. For example, what about fresh drinking water. If nothing is done soon, the world will be in crisis. Even countries with cold climates, in Europe, are facing a shortage of potable water because of the high population density. As people become Westernized they consume more water. They change from bathing when they can, to having showers every day. Production oil also impacts on the availability of water. it takes 2.5 liters of water to produce every liter of oil. Even growing bio fuels puts pressure on water, with a thousand liters of water needed to make a liter of bio fuel. The modern way of life is water "heavy": Wealthy people use 3,000 liters of water each day to live their lives. More drought in the world is putting prices of everything up. When water gets short it does so locally. Moving water from one place to another in bulk is problematical. In the shor

There is little sympathy for sole mothers from others in society or government. Social security payments have been tightened up by the federal Government. If sole mothers do not work they must go back to school, probably learning something that is useless for their future. Not many full-time workers have brought up children as well without paying someone else to care for their babies and toddlers. Older children are consistently being left alone as mothers do some sort of part-time work. This is reality. Part-time jobs do not pay well enough to provide money for carers. When Single mothers come home they not only look after their children, they must do all the household chores as well as do repair work to the home. The government's new harsher policy comes into force next January. Welfare payments will fall. Even those working part-time will lose some of the part-payment they get from social security. Children will be the real losers as food and heating/cooling are reduce

Google Gmail offers a new Internet phone service if you have a Gmail Account. There is one thing about running such a service on the Internet; that is it costs nothing for the company providing the service to run. Users pay a local telephone company for access to the Internet from their homes and on their mobile phones. The connection goes through each country via local telephone companies servicing the internet and phone lines. There is no charge for US Gmail users and a charge per call for those living in other countries. Though it is a small amount it is discriminatory. The Internet goes all around the world like a net. Access to this net is open to anyone. No country charges its population to access the net to other countries . The European furniture company Ikea has already been accused of cross-subsidization for charging different prices for the same products in different countries. The production and even distribution costs are much the same. Google's discriminatio

The common view on climate change (CC) has shifted. This is due to the shocking weather in the US over the last few years. A survey of respondents at Yale University shows those who believe that global warming is happening has increased from 57 per cent in 2010 to 66 per cent currently. People with common views have been identified: Alarmed - 13% Concerned - 26% Cautious - 29% Dismissive - 10% Disengaged - 6% Doubtful - 15% These figures were obtained in 2011, a year before the Yale study which noted the changes as follows: Alarmed - 13% Concerned - 26% Cautious - 34% Dismissive - 10% Disengaged - 2% Doubtful - 15% Other important opinions in each group include: Alarmed - 57% = Extremely sure CC is happening Dismissive - 94% = Strongly dstrust Pres. Obama ........ " .... - 70% = Strongly distrust climate scientists All Respondents - 58% = US could afford to act

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

A man had severe pains in his chest and began coughing up blood. Doctor Vladimir Kamashev x-rayed the man's chest and had a big shock. He had to call his assistant for a second opinion. The assistant confirmed the doctor's diagnosis. The man had a fir tree growing inside him. Fungus can grow inside a human body but it was not believed that plants could take root and grow there. Surgeons removed a young five-centimeter fir tree from the man's chest. Needles from the plant dug into the capillaries and caused bleeding. The man consequently coughed up blood. Obviously a small "cutting" from a fir tree was inhaled. It found sustenance inside body tissue. What is surprising is that a biopsy of the plant showed the fir needles to be green, so the tree somehow got enough sunlight to survive. Parts of the plant have been preserved for further study. http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspot.com/ http://www.feeds.feedburner.com/Adventure

The northern part of Australia is getting hotter, but it is no drier. A comparison of data from the 1950s and the present shows the borders between rain forest and eucalyptus forest remained the same. However, the density of rain forest increased by 732 ha. Neither drainage, geology, topography, aspect or elevation are responsible. The climate has definitely changed. Despite a series o f El Nino dry spells since the 1950s, the country is becoming wetter. This rain forest expansion has slowed over the last 2000 years, with 25 per cent being tall open forest. Eucalyptus forests are spread out in irregular shaped pockets which are very stable. Higher CO 2 is responsible for the increasing density of rain forest. The humidity keeps damage from fires low. Overall, this is good news for the world generally. Brazilian rain forest stores 250-300 C ha –1 (carbon per hectare) . Though Australian rain forest stores less, it is still significant. There is a possibility that local f

THE END OF THE ROAD FOR EASY WEB DESIGN Windows 8 means more problems for web page designers. What Internet Explorer reproduces in Windows 8 on a personal computer is not what comes out on a tablet. Internet Explorer 10 is the worst culprit. Having IE10 built into Windows 8 with no possibility of going back to IE9 is definitely a nuisance. Text goes right off the background square. On a PC, fonts are either extended too long and go over the background square at the bottom, or there is a line gap under the full stop because text is too short. Nearly all the other browsers reproduce correctly, except FireFox with the last word on some fonts extending to the next line. This is rare though. Obviously, the problem lies in the operating system itself which is designed specifically for tablets. Personal computers are only of secondary consideration. There is a "war" going on in the US at the moment over how images will be shown on tablets and even mobile phones. The powers

Tasmanian devils have a unique form of cancer. It is the only type that is contagious. Just how it is transmitted is the unknown factor. Scientists studying the disease now believe it should be reclassified as a parasite. Though at first glance it seems to be a cancer it has many characteristics of a parasite. The parasitic cancer stays in a host until the sufferer is irretrievably damaged then it will move on to a new host. It uses the Tasmanian devils predilection for violence to spread itself. It remains alive by sticking to the teeth. When devils fight they snap at each others' mouths causing blood to flow. It is really a new category of disease. Though a cancer it not in other animals. A parasite will exist in many animals. The disease originated in one female devil during the 1990s. Just how it originated is not known. It is such a difficult disease to treat. The Tasmanian devil could reach its demise in less than 15 years. http://www.adventure--australia.blog

Alien predators are the main danger to the survival of Australia's native wildlife. Foxes and cats are clearing many areas of native animals. Indeed, Australian fauna has been the hardest hit in the world. Bettongs (rat-kangaroo) and wombats for example are oblivious to the danger when a cat or fox is present. Australian prey have developed camouflage to defend themselves from native predators, but alien predators can see through this. Thousands of years of isolation have made native fauna vulnerable. Other continents have long had the cat, goat, grey squirrel, mouse, pig, rabbit, red deer, red fox and ship rat, so their native animals have learned to survive and avoid extinction.  Responsibility lies clearly with early European immigrants.  The damage was done a few hundred years ago. http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspot.com/ http://www.feeds.feedburner.com/AdventureAustralia http://www.technorati.com/blogs/ http://adventure--aust

The state of the weather is a problem on Earth with predictions not always being correct. In space, however, there is a more serious weather problem. Solar storms can kill. Detectors at the South Pole measure neutrons. When the level reaches a certain point astronauts on the International Space Station shelter in a shielded capsule. Advances have been made in predicting solar storms which can destroy satellites. Unfortunately, little can be done to protect them, but the safety of astronauts is paramount. Storms move at different speeds. The faster the speed the more energy in particles, which makes them more intense and dangerous. Ironically, because there are more low-energy particles in a solar storm they do most overall damage. The early arrival of these low-energy particles does forewarn the onslaught of the high-energy neutrons. The number of solar flares gives an indication of future activity, though this is only a possibility at best. Neutron sensors at th

A new cancer drug has been announced by Cancer Therapeutics CRC in Melbourne. CTx-294886 is to be used in conjunction with another medication, Avastin. Furthermore, a new type of scanning has been developed by the same company. It will identify protein homeostasis, a new pathway in cancer treatment. CTx-0294886 stops tumour growth by inhibiting Focal Adhesion Kinase (FAK) and Vascular Endothelial Growth Factor Receptor 3 (VEGFR3). This with Avastin reduces angiogenesis, slowing tumor growth in breast cancer. Examination of effects in head, neck and cervical cancers is ongoing. The company has already developed a primary anti-cancer medication, CTx-294945). Both drugs can now be used to prolong life when dancer is detected. Research was done with the assistance of Australian and international institutions. http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspot.com/ http://www.feeds.feedburner.com/AdventureAustralia http://www.technorati.com/blogs/ htt

Bare circles of earth ringed with tall grass are found all over Africa. They have been a mystery with all kinds of stories told about them. Now a partial explanation has been found. Walter Tschinkel has been studying the phenomenon since 2005. At first he thought they were caused by termites which poisoned and killed off the grass. He realized his mistake when he analyzed satellite images - the circles were alive! The circles would disappear then appear somewhere else. However, for the most part circles remain in one place for up to 75 years. The average life was 41 years. Rain tends to be the main factor leading to formation of a new circle. Tschinkel has not discovered the real cause. If fertile earth is put inside a circle grass still will not grow. Something is going on in a chemical or "living" sense. Locals do not want the mystery solved. They make a living out of them. For a fee tourists "adopt" a circle, then keep up-to-date by viewing it on Go

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
