Parents and Children Hit by New WA Drug Laws
Western Australia is about to fill up its jails and children's care homes in the war on drugs. New legislation will jail parents and take away children for the cultivation of one cannabis plant. The jail terms are mandatory for the manufacture of small amounts of other drugs.
The conservative government has certainly lived up to its ideals of trying to turn back the clock a century or so. Transportation to a far off land could be next for "criminals". An earlier Labor government had decriminalized minor marijuana use. Just why the WA government would want to change a situation that seemed to be working is the real question. The premier must know that tough regulation like in the US has failed, totally. If legislation worked, such action would be justified
Even in the UK, people found with a small amount of drugs on their person are given a warning the first time it happens. Only serial offenders are jailed. This is the best idea. Target the dealers not individuals who in many cases are experimenting. We let people damage their health by smoking tobacco. Allowing them to cultivate a small amount of marijuana for their own use is akin to that.

Rift Valley Created by Tectonic Event - Findings of Early Man Fortuitous
The birthplace of Mankind is believed to be the Rift Valley in East Africa. It was thought that the valley formed over a long period of time. James Cook University scientists in Australia have found that a tectonic event changed the flow of the Congo, Nile and other rivers thus creating the Ethiopian-Kenyan eastern segment, and the Ugandan-Malawi western branch.
Formerly the assumption was that this didn't happen at the same time. The eastern section developed up to 25 million years before the western segment. This was the prevailing theory.
The Australian evidence indicates that the tectonic event created the eastern and western branches at much the same time. Climate change models will now have to be reviewed.
Because the region is rich in fossils ongoing investigation occurs there. It is the only late Oligocene terrestrial fossil deposit in Africa below the equator. Though fossils of early Man have been found there, it may not be the actual birthplace of Mankind. If could just be fortuitous that evidence has been found there.

Elephants and Mammoths Have Much the Same DNA
Elephants aren't so different from woolly mammoths. DNA samples taken from mammoth hair shows they are much alike. Furthermore, there are indications that the mammoth population was so low toward the end that inbreeding took place.
If the unique mammoth genome can be isolated it can be inserted into elephant DNA to produce a woolly mammoth. It has also been found that differentiation between mammoth was only minor, so that a disease could have easily wiped them out.
Mammoth are more closely related to elephants than chimpanzees are to humans, which is about 99 percent. Evidence shows that there were two groups of mammoth. One group died out 45,000 years ago, the other 10,000 years ago.

Evidence of alien landings?Aboriginals Did Not Wipe Out Megafauna
The argument continues over whether humans were responsible for the extinction of megafauna. Giant emus, large kangaroos, marsupial lions and diprodons were destroyed by Aboriginals in Australia according to new research. This claim is based on fungi in dung of herbivores. For 130,00 years, despite dry periods, charcoal and pollen levels in dung remained the same until Aboriginals arrived. This means that climate change was not responsible for the extinction of megafauna 40,000 years ago.
There is a problem with this. When Captain Cook arrived in Australia the Aboriginal population was extremely low. Forty thousand years ago there would have been only a few hundred thousand of them. How could this low number possibly destroy all of the large animals? Some megafauna would have survived in regions where Aboriginals did not go. Australia is a very large continent.
It is claimed that when the megafauna died out the vegetation changed with more fires, and eucalyptus forests spread out killing off rainforests. Spores in dung is flimsy evidence to support a claim that human arrival led to the demise of megafauna. Rainforests being taken over by eucalyptus sounds very much like climate change. Furthermore. prevailing evidence shows no human remains among megafauna fossils.
Saying that the dung research proves humans destroyed giant animals is still not proven beyond doubt. Gavin Prideaux's announcement that the study "supported mounting evidence that climate change was not to blame" is premature.

Eggs of Mussels Attract Compatible Sperm by Releasing Chemicals
Mussel sperm have to find the right egg. This is not as easy as it seems. When the eggs are released they can be scattered through ocean water or river. While mussels are attached to rocks, eggs and sperm are at the mercy of the elements. The eggs have to let sperm know that the eggs are available, so they send out a chemical message to attract suitable sperm.
Many species release chemical signals. The message sent has to be differentiated to prevent fertilization by siblings. A test was done forcing sperm to fertilize chosen eggs. Only compatible matches gave healthy offspring. In a later test mussel sperm were observed to choose compatible eggs to produce health young.
This is the first time chemical attraction has been observed in mussels. It shows how important compatibility is in many species. This brings into question the theory of gene pools where there is deemed to be no barrier to gene pairing. The idea that any male and female can have offspring no longer stands. Even human eggs send out chemical signals to attract compatible sperm. Some human couples cannot have children even when tests show they are perfectly healthy. Fertilization can occur with a different partner.

Global Warming But Floods in Australia!
There is something strange going on with the weather. Despite reports telling us that Australia is becoming drier we are getting more rain than ever. They say that global warming will make it rain more but water will evaporate faster.
In Britain they may have to set water restrictions because it is raining less. Holding water in dams in Australia at the moment is a silly idea. With La Nina seemingly fixed off Australia's coast more and more rain is predicted. Some east coast towns, many inland, have had three house-destroying floods in three years.
The poles are melting. We know this. Yet long-term predictions about future weather for different countries is like water divining. It seems to be right, though the truth will be known only by what actually eventuates.
If the sea does rise and Australia still gets flooding rains people will abandon low, flood-prone regions permanently. There are only so many times you can repair a house. Australia will become what it has been in the past - hundreds of small islands. With new ports planned in this country to export more coal to the world this possibility becomes a probability.

There Is Soil on Mars
NASA scientists are now saying that "soil" on Mars could support vegetable life. Without an atmosphere, though, it seems no life is possible. Scientists are specific enough to say that asparagus and turnips will grow in Mars' soil but strawberries will not. Are they joking? Or are they for real?
The Phoenix Mars Lander found soil that is very much like that in many Earth backyards. Scientists are shocked that they have found soil. It is alkaline - thus, the claim that it is not good for strawberries. Apparently, the soil is rich in trace minerals.
My, how scientists can be wrong. It was thought that Mars "soil" would be salty - with no atmosphere and the sun would bleach it. But they were wrong. At least we know that there is soil and water in the form of ice just beneath the surface. There is evidence that in the past water flowed on the surface because erosion is evident. Rivers, lakes and oceans existed there once. Water reservoirs such as these indicate that the planet did once have an atmosphere.
If life did survive for a time on Mars future exploration will surely find it.

High Rents Put Pressure on Low-Income Earners and the Poor
A fall in house prices is a good thing for first home buyers, but it puts a squeeze on the rental market. With lower property values investors invest in other things, the bank or the share market. You would think that rents would move up and down with the price of housing, believing that monthly rents are tied to monthly mortgage repayments. This is a generality that is not always true.
The reality is that as house prices fall, rents go up as investment to built more rental properties declines. In Canberra rents increased by 2.2 per cent last year. Perth continues to experience a drain of money to mining areas from Perth city itself. Consequently, new rental properties have not been built and rents have also increased.
Those on low incomes who do not earn enough to get a mortgage are at the mercy of the rental market. As rents rise they have to pay more. Furthermore, students from poor families cannot afford to pay high rents.
Despite the mining boom in Australia, many are doing it tough. Unemployment in the non-mining sectors is starting to rise. A high Aussie dollars makes it difficult for manufacturing to compete. The big question is: Should Government support non-mining industries?" Economic rationalist would say no. The market should determine who should survive and who should go under. Nonetheless, pensioners have rents subsidized. Should this support be taken away?

"What a poor example of a dog."Scout Bees Have "Curious" Brains Like Humans
It was thought that bees were like robots who went about their work on instinct alone, but some bees have "curious" genes. The scouts who find sources of food are actually mischievous seekers. Their genes give them a brain structure similar to humans.
Scout bees are independent creatures who don't go along with the mob. They find new food sources by intuition and pure skill. Being female, they go back to the hive do a wiggle dance to pass on directions, then go out again to find a new source.
Tests were done on a hive of bees. The hive was put into an enclosure and food was put out in different colored jars. Bees that located the jars were collected and marked with a dot of paint. Later the brains of these scout bees were removed and compared with the brains of normal hive bees. Brain activity in the genes of the two types of bees differed by 16 per cent. The brains of scouts could change the levels of neurotransmitters dopamine and glutamate. Another test was done with the scouts being fed sugar water laced with a neurotransmitter "booster", The scouts became more active in their search.
This proves that dopamine and glutamate are responsible for curiosity in humans. The common ancestor of bees and Man was a marine flatworm. These basic animals would not have had scouts, so the "curious" genes developed in both lines, bees and Man, separately. It is also probable that the gene variant can become active in any animal: it is latent in the gene toolkit.

Development Is Tied to the Availability of Water
Karl Marx said that Mankind developed through political and economic stages. Scientists have proved that he may have been partially correct, but the key to human progress is water.
Professor Terje Tvedt of Norway says "that water has played a unique and fundamental role in shaping societies throughout human history." Scientists have made a mistake by ignoring the presence and impact of natural resources on human development. All societies need water. A society cannot operate without it. You can try to control it. Yet water appears and disappears as it pleases according to the flow of nature.
Why did the industrial revolution happen in Britain and not in China or India? The reason it occurred was the capacity to move goods via canals. Furthermore, production of grains and cotton products by the power of water mills created a need for bulk transport of goods. British rivers were clear. Boats could move quickly through them. Unlike rivers elsewhere which were silted up.
There-in lies the problem of economic development. Not all countries today have developed transportation and water supply systems. A concept called the "water footprint" is being examined. The footprint is the amount of water required to make the goods and services in an area plus water polluted and evaporated per unit of time. Under this system Australia becomes the world's largest exporter of virtual water, with Europe being the greatest importer.

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.

Japanese Fast Food Chain Storms Australia
Just what Australia wants - another fast food chain. The Japanese are invading Australia with a burger chain, MOS Burger, which is a copy of McDonalds. The fourth store has opened in Booval, Brisbane. For some reason the chain is targeting Queensland for its new outlets.
The company claims, of course, that their offering is different than McDonalds. Project manager Vincent Cheng says they offer better service. This is difficult to justify considering service at McDonalds is second to none. When was the last time you waited for more than five minutes to order and another five minutes to get your food?
What potential customers really want to hear is lower prices not better service. The market place shows that when customers have a choice between paying extra for service or a lower price for the product they overwhelmingly choose the cheaper price. With another 10 stores opening in Queensland this year and further developments in Sydney and Melbourne time will tell if their massive investment is worth it.
If they sell food which is basically Asian they will be doomed to failure. Aussies don't like change.

Bacillus subtilis a Useful Bacterium
New work on old bacterium shows promise. Bacillus subtilis has been used as a base organism to make vitamins and enzymes for washing powder. Nine countries including Australia have taken an in-depth look at Bacillus subtilis and the way it can survive in different environments.
Evolution has made B. subtilis thrive and have a strong metabolism. The findings will enable the creation of metabolites for chemical and pharmaceutical industries. There is greater understanding of how bacteria survive when infection changes the environment. This bacterium is now much more useful in producing enzymes.
In the study 512 new genes were identified in B. subtilis. These were added to the 4,200 previously known genes. It was believed that only a few genes needed to be modified to makes changes, but it was found that up to half of the genes needed to be targeted. Despite this it has been a great leap forward in science.

Dogs Eats Car in Australia
Keep an eye on your car - there are wild dogs about! Clayton Dwyer's girlfriend called him and told him to look at his car. The front bumper had been torn from the car and gnawed into bits. Dogs had even bitten into steel front panels.
Mr Dwyer found it hard to believe that wild dogs would do such a thing. He had seen the pack wandering around the neighborhood.
His girlfriend admitted to him that the dogs had attacked her car some months before. At first it was thought that someone had done the damage with a hammer. But panel beaters could make out teeth marks on torn parts of her car.

Tranferring Human Minds to Robots Is a Pipe Dream
Some people assume too much. This applies to the scientific sphere where people can "get ahead of themselves" and make claims about achievements that are only in the "possible" stage. Science is advancing very fast, but some things are still out of reach. People in positions of power due to wealth or public office can make the wrong decision.
A group of 100 scientists have been put together by Dmitry Itskov a Russian entrepreneur to download, or upload depending how you look at it, human minds into robots. This is fairy tale stuff. They expect to complete this within 10 years. This is probably at least 30 years away.
These human/robot "things" Itskov has called Avatars. He claims it will mean immortality for humans who agree to have their minds "implanted" into robots. This is a silly point of view. Unless consciousness is transferred as well there is no immortality. Claims that consciousness will be transferred with the mind are nonsense. Neither scientists nor theologians know what consciousness is anyway.
The idea has of course been taken from the movie Avatar. Why Itskov should depart from the script and presume consciousness can be moved with the mind but the body must die is not clear. In the movie humans return to their bodies after cohabiting alien bodies on a colonized planet.
