Aboriginals Got to Australia Along Two Routes in Southeast Asia

There is a mystery about how Aboriginals first came to Australia. No evidence has come to light that shows there travel from Africa to the Southeast Asia. Artifacts in Australia date to 65,000 years ago but evidence in SEA only dates to 45,000 years ago and they are different people. Two likely paths to Australia are the northern route and the southern route.

Cause of Sudden Death in Young People is Genetic

Sudden death in young people has a genetic cause - Long QT syndrome.
There is a predilection for some young adults to suddenly die. In a way it is similar to cot death: until now the cause was unknown. The "disease" has been identified and is called Long QT syndrome. A third of sudden "unexplained" deaths in people up to their mid thirties die of heart rhythm complications due to the inherited illness. The heart problem is not always evident in autopsies.
Long QT syndrome
Parents can also die of the condition in later life. The faulty gene runs in families and is generally passed on to some offspring. A gene testing study of children having symptoms of heart disease is showing that many carry the gene. 

Ongoing monitoring of youngsters is saving lives.  However, there is no official program that tests all children.  Some, of course are not diagnosed early and it is these who are at risk of sudden death.  It is heart breaking for a family to lose a child in this way,Ea

Physics Not for Females - Women Say!

More women are moving into academia every year. This is the overall picture. Some areas are still sparsely populated by women. Physics is such a sector of learning. Name a woman physicist - any woman! Few recognise that maths is easier for men, but this is true. There is something about the male hormone that creates this state. Just like women are better at using words.

Notably female physics students at the University of Melbourne have admitted that most women do not have the capacity to master physics. There will always be a few exceptions. However, the reality is that generally, women find study in this specialty difficult. Many female students who try physics ultimately end up in chemistry. They do feel more comfortable there.

The survey of first year females showed more than 50 per cent had a negative outlook of their chances of succeeding. This makes one wonder why they are in the course. However, some were studying physics as a requirement of other degrees.  Oddly, some said they enjoyed studying physics.

As a positive, fourteen students were studying advanced physics at the University of Melbourne and were ambitious to achieve their goal. They are definitely thin on the ground with all the males. Another issue is that women do not see physics as a career path. You cannot get work in finance or banking with a physics degree, for example. Research and teaching are just about the only sectors for employment.

High school is where all this begins. A good start in maths in essential. Giving students the choice to do only standard maths must be changed. All student need to do some higher maths, particularly in this computer age. It is human nature to choose an easier option. There is something wrong with the Australian education system: women dominate Italian advanced maths departments.

Toll Roads Do Not Pay!

Toll roads just do not pay. At least in Australia they don't. Councils and states have praised projects before they begin construction, boasting of the benefits of new toll roads. At best such schemes can only expect to break even.

Drivers use it for a while with low introductory tolls. When the tolls are raised people change back to the old route. A toll is a dinner for a truck driver. Ordinary people just do not calculate the extra cost of petrol to avoid a toll road.

AECOM Technology did a feasibility study for a toll road. It grossly overestimated traffic flow. In short, it knew the numbers were inflated and knew the report was full of lies.  The company said if the court challenge to them is upheld it will bankrupt the business. The claimants are seeking three times the whole yearly earnings of the company which is based in the U.S. This is gross earnings, before depreciation, tax and amortization.

This amount is based on the bankruptcy of the RiverCity Motorway groups that built a toll road based on the AECOM report. AECOM is in trouble because several large banks financed the project and when it comes to legal cases they have bottomless pockets.

The initial report was superficial and done quickly at a low price of A$2.5 million. Banks say they have lost more than A$1.68 billion. When RiverCity failed the toll road was bought at the bargain basement cost of only A$618 million from the receiver, KordaMentha .

Other toll roads are now preparing their own court challenges to inaccurate reports that go back many years. Feasibility studies are notoriously incorrect. It is about time things were put right and governments took on the full responsibility of building new road. They take a large slice of tax from road users and spend it on other things.

Men Choose Degrees That Provide Good Incomes

There is a reason more women are not in high income occupations. Let's face it the truth is the truth - most women do not have a mathematical mind. It is based on evolution where women developed social skills to collect berries and tubers. Men on the other hand had to hunt dangerous large animals and this needed calculating brains.

Even today the sexes express their differences. More men choose university degrees in maths, engineering, technology and science. This where big money is earned. Humanities degrees especially the common or garden Bachelor of Arts will leave you in the unemployment line.

Australians generally persist in studying for a BA despite all the statistics showing how weak this honor is. They know it is easy to get, but the easy way is not the best and more rational way.

Just choosing a non-humanities degree is not that easy for females. A few have extremely good mathematical skills. They are at least equal to men. Most do not have the mental precondition to do well in maths at school.

As an example, a quarter of men choose engineering degrees. Only 3.7 per cent of females choose this course of study. The only "maths" area of science studied by more women than men is veterinary science.

Study Shows Optimistic Cancer Sufferers Live Longer - Or Does It?

Treating the effect as the cause is wasting valuable time in finding a cure for cancer. A Study found that depressed people lived shorter lives when they had cancer. Depression per se and lack of hope, optimism and anxiety were tested. Those suffering from these "attributes" didn't live as long as "optimists" who were also cancer sufferers.

A great leap of faith was made to claim that mood sufferers did not seek second opinions on cancer. Note that this was not proven it was just surmised. Overall findings were that optimism did not lead to better survival in people with cancer. Well this is game. set and match. You can't have it both ways. Either being optimistic improves survival or it doesn't.

There is no doubt that psychological treatment improves the well being of cancer patients, but let's not get ahead of ourselves and say optimistic cancer sufferers live longer. A great deal of money is set aside for medical research. We have to be careful to ensure this money is well spent.

New Lizard Found Near Perth

Despite the idea that everything is known about everything, the area of discovery is still wide open. Just outside of Perth in the sand dunes a new species of lizard has been found. It has been given the name Ctenotus ora.

There are concerns that it will not be around for much longer. New housing is encroaching upon the coastal plains skink's land. The lizard was identified during an Australian National University study into biological diversity in the Perth region.

Just how many of the lizards are out there is not yet known, so their prospects of survival is still an open question. The area of sand dunes where they live is getting smaller. Unless the state government steps in to stop it, urbanization will see most of the dunes concreted over.

The southwest of the state has not been explored in great depth. Other new species are probably waiting to be brought to light. Though people have been there a long time, concerns about work and shelter have been the priority not biological research.

Consuming More Tea and Coffee Prevents Diabetes - Doubtfu

Claims about consuming certain things to improve health are way off beam. Every now and then supposed new research shows that if you eat this or don't eat that your health will improve. Years late we discover that the "experts' were totally wrong and your health was actually damaged. This happened with margarine, milk, eggs and so on.

What is the latest? Well, apparently drinking up to three cups of coffee or tea each day reduces the risk of getting diabetes. Look around. Do you see people who drink these beverages regularly with diabetes? You sure do. There are thousands of them.

The University of Sydney says “If such beneficial effects were observed in interventional trials to be real, the implications for the millions of individuals who have diabetes mellitus, or who are at future risk of developing it, would be substantial.”

Their trials must be wrong. Surely millions of regular drinkers who have diabetes are thinking, "Why me? Why have I got the disease". Eight percent of people in the US have diabetes and many of them drink coffee every day. In fact tea and coffee are two of the most consumed commodities on earth.

When you read the text of research papers two important factors are played down: exercise and weight loss. Another issue is the finding that consumption of decaffeinated coffee reduced risk even more, so caffeine did not "cause" this reduction. Decaffeinated coffee is identical to ordinary coffee in every way except the caffeine level.  Could it be that heavy tea and coffee drinkers consume less sweet soda?

Search for Smart Genes

It seems the level of intelligence is determined by a few genes.  This must surely be too simplistic, particularly because specialists cannot agree on what intelligence is.  How do you compare memorizing general knowledge to the skill of knitting a fine jumper?  There are people who know just about everything about Australian rugby league, but this is their only area of expertise.

Finding will be made easier, apparently, by questioning the crowd rather that by brain scans, etc.  It is believed that the sought after genes affect brain size.  Considering that Neanderthals had larger brains than modern man, this seems to be the wrong hypothesis to start with.

While "the team" is sure they will find the genes they do admit that culture, education, health and upbringing can affect intelligence.  How are they going to filter these things out?  Obviously they can't.  Twenty one thousand subjects were catalogued and brain imaging was used.  Strangely, when the team was reaching its conclusions they discovered that another group was doing the same research with more people.  Now that is clever.

Financial Encouragement Is Needed in Computing and Maths

Despite the widespread use of computers, Australia is not producing enough qualified computer specialists. Although the computer related economy is equal to mining, and the extractive industry is what is driving the Australian economy and keeping the dollar strong, too few young people are willing to study for employment in the digital industry.

This is probably because everyone is a little computer "savvy" and most believe that there is not much more to learn. Of course this is a mistake. You may have a website and know a trick or two, but there is a barrier that you cannot jump over if you are to truly understand the whole area, unless you are a born computer geek where you soak up all the knowledge like a sponge.

What academics fail to understand though is that computer study is very much like learning mathematics. Students are avoiding maths like the "plague" because there are much easier subjects to do. For example, English and History teachers are a dime a dozen. This has been caused by governments wrongly allocating funds in the past. Universities and colleges are also to blame as they try to maximize student numbers irrespective of subject area.

Financial encouragement needs to be in place to tempt students into the "difficult" kinds of study. Some people have a gift for maths. Ironically, today many of these are girls. In the past boys believed maths was a boys' thing and they took pride in studying it. Cutting tertiary fees in the maths and computers areas is absolutely necessary to bring numbers up to the nation's requirements.

Australian and US Institutions Work Together on Biofuels

Despite claims that growing crops for fuel is pushing up food prices the University of Queensland and Carolina's Clemsen University have signed an agreement to develop biofuels. The work will revolve around transforming sugar cane residue into fuel using algae. A pilot plant is to be built in Queensland. More research on cellulosic monomer conversion will be done.

Clemsen University has concentrated on converting sorghum and switchgrass into ethanol. A new base called loblolly pine is also being examined.

This combined project will benefit both institutions. Pooling funding and resources will speed up projects. Despite possible drawbacks of biofuel it is intended to seek further funding and press on with research.

Eat Pork and Lose Weight

For many years it was believed that pork was fatty and if eaten regularly would lead to weight gain. A new study has shown the opposite to be true. Overweight people were split into two groups. One group was given 1050g of lean pork each week. The other group was provided with 750g a week. Even with this little difference in pork intake, after six months there was a noticeable change in the high-intake group.

Those eating more pork actually lost fat from their abdomens. Waists were narrower. Body composition improved over the whole body. So weight can be lost without dieting if you eat more pork. A further benefit from eating more pork is the high thiamine level. Many overweight people have type 2 diabetes which can lead to thiamine deficiency.

Tests are now being done with chicken and beef to compare with pork. It could be that the high-protein diet due to eating the pork was beneficial. Maybe similar results in regard to weight loss will eventuate from eating more chicken and beef. Findings will be released in January 2012.

Dark Energy Exists

Dark energy is no longer theory it is fact. Evidence from 200,000 galaxies confirms the hypothesis that dark energy is pulling the universe apart. It is a constant in that it pushes uniformally causing steady expansion of the universe.

Einstein was correct after all. He said there was a force pushing out stopping the universe from collapsing. This was known as "Einstein's biggest blunder'. He had to enter something into an equation which stopped the universe from collapsing. Though he didn't use the term "dark energy", this was the force he was talking about. He was wrong about the universe being static but he quickly revised his ideas when Edwin Hubble found that the universe was expanding. Gravity is no longer accepted as the force driving the universe apart. Gravity cannot push and pull at the same time.

Calculations show that dark energy makes up 74 per cent of the universe. Dark energy is not he same as dark matter. There is 22 per cent of dark matter out there. This leaves 4 per cent for all the atoms making up physical things.
