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...

New findings on Alzheimer's have been released in Australia. The build up of beta-amyloid plaque is thought to be the main cause of Alzheimer's and it is also responsible for cognitive decline over the long term. The presence of plaque in the brain enables diagnosis of Alzheimer's even in people who show no immediate symptoms. This was announced by Dr Christopher Rowe, professor of nuclear medicine at Melbourme's Austin Hospital. A patient can now know years in advance that he/she will develop Alzheimer's. Whether this is a good thing is debatable, though it does give time for a person to get their things in order. Depression could be the result of making such an emotive discovery. Eighteen million people suffer from Alzheimer's worldwide. With the large segment of the population moving into the elderly group this is expected to reach 34 million by 2025. A new drug to fight plaque has been approved in the US. Hopefully, a medication can be found that ...

The culture of Greece is at risk and this is where democracy was born, Surely, funding can be found from other countries. National cuts have reduced the archaelogical workforce to a dangerous low level. Up to 50 per cent of workers in total will be dismissed, Just maintaining ancient structures is expensive. Of more immediate threat are museum pieces, not fixed ancient buildings though illegal diggings are threatening these. museum security guards have been laid off. Armed robberies are increasing. Offical research projects funded from other countries are continuing. but all local digs have ceased as the money is stopped. Work on ancient walls built in the time of Pericles located under the metro rail line, no longer takes place. The dig is important to understand how the access way from Athens to the sea affected the way the fleet of ships was used during the Peloponnesian War. There will be a real loss of experienced specialists as they take early retirement. Those left spend...

It seems that with climate change we will lose some species but gain new ones - or have new "changed" species. Some species living at high altitudes have been changing as mountain tops become warmer with climate change. It was believed that accelerated evolution only occurs in cold regions, but it has been discovered that it also happens in the tropics. While it has been accepted for a long time that plants and marine protists evolve faster, the process has only recently been recognized in mammals. What is unusual is that mammals are not directly affected by a warming climate because they naturally maintain a steady body heat. It is now believed that evolution in the tropics is even faster that in temperate regions. There is a greater diversity of species in the tropics. This faster evolution and more species means that adaptation to changing conditions is rapid. The faster evolution actually makes for many more types of animals. There must be something else, however, t...

The era of academic journals being closed off from the general public by financial barriers is coming to an end. Publishers are terrified by this. It means they will have to get funding from other sources rather than annual subscriptions. There will be a time limit placed on articles, so after a short period they will have to be released so everyone can read them. This move is being put forward by the UK government. It is pushing for open access from the very beginning of publication. Unfortunately, the government intends to make authors pay publishers. This is unrealistic. Admittedly, university lecturers are in a secure financial position. However, scientists find it difficult to get funding and allocating part of income on publication is another financial burden. Universities are saying that the government is looking after publishers, protecting their income while passing the cost onto educational institutions. Martin Hall says we must move forward to get full funding in ...
