Agriculture Disrupts the Ecosystem
Human impact on native flora and fauna is real. There seems to be no way the detrimental affects can be ameliorated. Aboriginals have been in Australia for 40,000 years. apart from the unanswered question about extinction of mega fauna Aboriginals did not alter the external environment at all.
Sedentary agriculture is the major contributing factor to habitat damage. Planting mono-crops seriously changes land features. In Western Australia, for example, water points are located at 50 sq km on average. In its pre-European natural state water holes could be found 2.5 sq km apart. This is serious change with species of native birds declining.
Unless we set areas aside as pristine, protected sectors only introduced pest species will remain. Even without the pest birds, the proportion of native birds is altered. Some die out while others increase in number. The ecosystem is no longer in balance.

Donkeys and Mules Are Celebrated
Donkeys and mules are not forgotten. There are people out there who care a lot for these animals. They have established the Donkey All Breeds Society of Australia National Donkey and Mule Show. They deserve a medal for creating such a long title for the celebratory weekend.
Entrants were brought in from all over Australia. The tiny Mediterean Miniature donkey was the cutest in the show. Very large animals were represented like the 16 hands high American Mammoth donkey.
Many animals performed for the spectators. It is a myth about the independent, angry mule. Indeed, they like to be trained. Donkeys really put on show in the trail, driven, sulky, halter and snigging classes. Trainers were as young as five years old. Some donkey entrants were elderly, in their mid-twenties. The show was such a success that it will continue. It is affectionately called the long ears show.

Imaging More Advanced Than MRI
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.

Models Show Lasers Can Produce Energy Using Hydrogen-Boron as Fuel
Energy created by lasers could be the way of the future. Researchers have used models and they show that lasers can produce "cold" energy by nuclear fusion. A new generation of fast, powerful lasers makes this possible. To achieve fusion a short, carefully controlled pulse is required. The pulse target is hydrogen and boron. Creating neutrons is not the objective because they cause radioactivity.
The Australian research is duplicating what is going on at the National Ignition Facility at the Lawrence Livermore National Laboratory in the United States, but they are using deuterium-tritium fuel.
A single laser pulse can generate 500 times more electricity than all the power stations in the US. At first the research team did not believe hydrogen-boron fuel would work. However, models indicated that it was only ten times more difficult than deuterium-tritium. For it to work the laser pulse must be clean, that is, lasting only a million, millionth of a second. Optical energy is then converted to mechanical energy.
It is not commonly known but coal power stations actually emit radioactivity - it is a problem in Germany where they are considering burying polluted material. Producing energy by laser pulsing hydrogen-boron creates less radioactivity than using deuterium-tritium. Coal generation is very dirty compared to hydrogen-boron. The waste product is helium gas. Hydrogen-boron is also plentiful. Team leader Professor Hora say it could be some time before the research becomes reality.

Return on Savings to Fall
Banks are to significantly cut the return on money invested. This is not surprising considering the Reserve Bank of Australia (RBA) is cutting interest rates. As the banks follow the RBA down, which they are not obliged to do, they must cut outgoings on term deposits for example.
Considering banks make 60 per cent of their funds from various savings products, it is no wonder cutting what they pay out is on the horizon. If rates fall much lower people will be drawing out their savings and hiding their "loot" under the bed.
Customers are borrowing less because the bar for loans has been pushed too high. Well, perhaps that is a good thing. Australians were condemned for not saving enough; now they are criticized for not borrowing enough.
With an election date already set the government will push for full RBA flow-ons in the popular media. This does not look good for retirees who rely on money put aside in investments for their retirement. Money is getting cheaper in the wholesale market so fewer deposit options will be offered by the banks.

"If someone doesn't adopt me soon, I'm going to break out." Spicy Food Stimulates the Same Endorphin Centers as Alcohol
It is well known that alcohol increases one's desire for spicy snacks. The personal drive not to eat is also weakened. This is why it is widely acceptable to head for the local curry shop after a drinking session.
It is believed that the two drives support each other. Those who like spicy food when they are sober tend to be heavy drinkers of alcohol. Both spicy food and alcohol stimulate the same centers in the brain. There is hope: spice lovers respond better to medication that reduces alcohol dependency.
It is all to do with the feel-good chemicals put out by the brain when stimulated. More endorphins are released by both substances. Because many people do not experience raised endorphins when consuming alcohol, drugs that lessens this affect do not work to stop alcohol consumption in them.
It was found that making "alcohol endorphin high" mice eat spicy food before offering them alcohol stopped them drinking as they were already getting the spicy high.
Apparently, there are two forms of alcohol dependency. One that is driven by endorphin highs and another in genetically 'low endorphin' people who crave alcohol for an unknown reason.

New Zealand Wants Drivers to Wear Gloves
Calls from New Zealand to cover up one's hand by wearing gloves when driving a car is silly to say the least. This may be something to think about if one is a delivery van or a truck driver but ordinary people don't drive enough to warrant it. They say the belief that glass provides protection from ultraviolet radiation is a myth.
Sunscreen maker "Oasis Beauty" has suggested putting sunscreen on hands before driving. This is sound advice, coming from a producer of sunscreen. The International Agency for Research on Cancer says drivers should wear gloves, long sleeved shirts and sun glasses. Unless one is a professional driver this is a bit much.
Car producers state that laminated windscreens do block UV radiation: 80 percent of UV-a. It is side windows that are dangerous, though 37 percent of UV-a and 97 percent of UV-b are blocked. From these data obviously the New Zealand Cancer Society and Oasis Beauty are wrong and car glass does offer protection. Furthermore, most countries do allow side windows to be tinted which helps.
