technology Despite the advances in artificial intelligence, useful robots are a long way off. Humans can do limitless things, whereas robots can only do one thing well. They cannot have the broad perspective. So don't hope to have a "Maisy who washes the dishes and cleans the house anytime soon. Businesses want to profit from new technology. However, adapting quickly to advances in artificial intelligence is difficult. The business that shows the way will be the winner. Those who follow will have to pick up the scraps. The leading business will have moved on to something else. The time is approaching when the first damaging, even fatal, decision is made by a computer. It could be a major disaster. Artificial intelligence is not sentient: it does not feel any harm it does. Machines can now learn both good and bad. To a computer everything is equal. Give a robot a conscience - that will be a great leap forward! ◆ Technology by Ty Buchanan   ◆ Adventure Austral

Australian scientists are still working feverishly toward producing a quantum computer. Two kinds of qubits, the building clocks of a quantum computer, have been made. Silicon is the base material which is the normal chip mineral. Below the silicon base, atoms are the working parts. They are the storage medium. More data can be manipulated than in traditional computers. The error rate for quantum computers has been dramatically reduced. Because two teams have made different chips and working computers, it means major production is imminent. Silicon is plentiful and relatively cheap so cost is not a major problem.  There will be a rush to make a working computer and mass produce it. The two systems are different. One uses an embedded phosphorus atom, the other an artificial atom. The Dzurak chip can be made in existing factories as it imitates normal transistors. Both chips can hold memory for 30 seconds which is sufficient to do complex work. Obviously one sys

One of the most difficult things to do is to develop a computer brain that operates like a human brain. Intelligence that evolved by nature is very complex. A computer "thinks" linearly with one activity followed by another. The human brain works outward from a central point, spreading out to different areas depending on the particular task. To say that Australia should concentrate on making the world's first bionic brain is a leap too far. Saying that $250m over ten years will get the job done is way off the mark. There are many scientists already working with much more money than that and they haven't achieved much. Pioneering the bionic ear and eye is kid stuff compared to replicating the brain. Using nerve activity to make artificial limbs move is also far from understanding human intelligence. Even after all these years measuring intelligence is beyond us. The IQ test only gives a score for rating cultural knowledge. It is misused by so many peo

Artificial insemination is common these days particularly to produce better animals for meat in the market. Cattle, sheep and even horse insemination could be said to a be the norm. Higher quality animals is the goal. Should artificial insemination be used to improve animals kept as a hobby? Breeding show budgies is taken very seriously by many people, so much so that widespread "cheating" takes place. Clipping of cheek patches is not allowed but it is still sneakily done. High quality show winners are usually produced by putting fertile eggs from good birds under "sitters", common budgies with a better breeding instinct. Michael Pace went to extremes to breed his prizewinner in the opaline class at the Australian National Budgerigar Championships. He practiced artificial insemination in his own way. A capillary tube was used to extract sperm from the male which was then inserted into the female within six hours. A lot of hit-and-miss took place. It took

The MRI was the most advanced way of diagnosing what patients were suffering from. It was cutting edge technology that gave very detailed images of the human body. Technology moves forward and advances are made. Macquarie University with CSIC and the Institute of Photonic Sciences (ICFO) have found a way of producing images even clearer than MRI. It is done by using artificial atoms and nitrogen doped diamond nanoparticles. Extremely weak magnetic fields in the human body can now be detected. MRI resolution is millimetric. The new system "sees" down to a millionth of a millimeter. This technique is not invasive. It will provide an understanding of intracellular processes. The problem with the new diagnostic system is that very temperatures are required to make it work. Artificial atoms are encapsulated in a diamond crystal. They can be manipulated by lasers, dragging atoms above the surface for medical diagnosis. http://www.adventure--australia.blogspot.com/ http:

For a century now people have been assuming that robots will arrive and become commonplace in the home.  Manufacturing has its industrial robots but helping robots in the home have not become reality.  The problem is not so much being able to construct the physical aspects of a robot, it is the intelligence, the "brain", that is the big issue. By doing 25,000 runs on a computer to build up experience, it was found that biological intelligence was structure into a network of modules.  This is a breakthrough finding for artificial intelligence.  Modules means alternatives can be chosen to meet a problem.  This is what makes humans and animals so difficult to understand. Apparently, all things evolve via modules.  Such networks have not solely appeared out of intellectual necessity.  Modules can be joined together with shorter network connections, using less to make more.  Evolution is not wasteful.  In the computer simulation, once a cost for network connections was added mo

Superman or indeed cyberman could soon be with us. Artificial muscles that can hold thousands of times their own weight have been invented. The breakthrough has been made by a team from four nations: Australia, Canada, the US and Korea. Carbon nanotubes were first wound into yarn in Australia. This super strong material far exceeds the flexibility of other artificial muscles. This is not strictly new. It was done several years ago but now work is under way to apply the technology. The yarn is does not yet have enough mass to be used for arm or leg muscles. Ideally, better heart valves, pumps, and positioners could be developed. The yarn has an interesting property: it can be made into a helical structure that will rotate right or left. Applying an electric charge causes it to spin. This makes it easy to propel a tiny object along in the bloodstream for example. This new discovery could revolutionize medicine. http://www.adventure--australia.blogspot.com/ http://www.tysaustral

There has been a weird finding in research done on IVF children - they are taller than average. Work done in New Zealand has found that by six years of age children conceived by IVF are taller. This occurred when fresh embryos were used, but not with frozen embryos. The higher quality of fresh embryos was the apparent reason for this. No benefits nor disadvantages were seen in children born using frozen embryos than children conceived normally. The real issue is - Are fresh embryos really of higher quality? Donors giving frozen embryos are just as selective. About one in thirty children are now conceived with IVF. It is girls who are notably taller. Another "weird" outcome is that mainly boys will be conceived if the embryos are left out in a dish for five days before implantation into the uterus. http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspot.com/ http://www.feeds.feedburner.com/AdventureAustralia http://www.technorati.com/blogs/http://adventu
