Australia's Pipistrelle Bat Will Be Extict Within a Year
Australia is about to lose the Christmas Island pipistrelle bat forever. Wildlife experts say the government is not doing enough. Only 20 of the small bats remain on an island in the Indian Ocean off the coast of Western Australia. The small group are staying together under the bark of a tree.
Watchers say the only answer is to collect all of them and try to breed them in captivity. Otherwise, they will be lost. The government has offered to set up a breeding program for a related small bat, but this will not save the pipistrelle. A zoologist, Mr Penney, says the species will not exist this time next year.
Scientists are planning to collect the bats and set up a breeding program themselves, ignoring the government. The government is not paying attention to the scientists, so that is what will happen.

Triathletes Need to Consume Carbohydrates
This subject is topical at the moment with the Olympic Games in full swing. The triathlon is a popular sport where spectators admire the determination of athletes to push through the pain barrier and keep on going to the finish. Little work has been done on understanding how much damages is done to the body.
The half triathlon also called the intermediate or Standard distance run at the Olympics has become popular with many who just want to keep fit. Tests show significant reduction in knee extensor and flexure muscle strength at the end of an event. The ability to jump up off the ground is also reduced.
Considering dehydration and stores of carbohydrates which have been lost it is no surprise that weakness continues for some time after competing. However, dehydration was only minor in tested athletes. It seems the fat and muscle loss is the main cause. Participants in triathlons should concentrate on ingesting carbohydrates as well as fluid. Keeping blood glucose high has been found to maintain muscle force. Male athletes improved their race times by consuming carbohydrates. This was not the case for females. The reason for this is not clearly understood. Female metabolism must preserve carbohydrate stores even during strenuous exercise, but carbohydrate intake is recommended for women during an event.

Geckos Cannot "Stick" to Wet Surfaces
Geckos are being studied to find out how they can climb across ceilings without falling off. Their toe pads can support weight equivalent to two people.
Like many animals with the capacity to "stick" to things, the main reason they can hold on is the many tiny hairs on their suckers. A hair is further divided into hundreds of gripping setae. The attraction between molecules in the surface and the millions of setae add up to significant sticking power.
Water is their enemy. If a surface is wet they fall off. Even on a dry surface, when gecko's feet are soaked in water they cannot hold on. Water tends to stop the superhydrophobic attracted between molecules. This is why geckos lose their wonderful climbing ability. In the wild they would be open to attack from predators in wet conditions. Furthermore, the hope of creating a new adhesive based on geckos is dashed.

Dangerous Chemicals in Household Products
Be careful what you put on your skin - the skin absorbs chemicals on its surface. In other words your body consumes and ingests things like soap and toxins in engine oil, etc. Little research is done on this serious issue. In New Zealand a dangerous chemical which lowers IQ in children has been found in sunscreens. It is as damaging as lead paint.
Even spraying the chemical into the air where is can be breathed in and ingested can lower IQ. Piperonyl butoxide is also present in insect spray. Cancer Society products even contain the substance.
Low vitamin D has been blamed for many diseases when in fact it could be trace chemical in commonly used household goods. If vitamin D deficiency is causal then people in temperate countries would have higher cancer, Alzheimer's, heart disease, autism, depression and ADHD than those in tropical regions. This is only true for some of these illnesses. Too say 31 per cent of Australians in this hot country are deficient is ridiculous.

The Energy Crisis Has Been Solved
The energy crisis has been solved - no more pollution or high fuel prices! Just get a "slave" to pedal away all day while you enjoy the electricity generated. A joke? No this is no joke. Scientists are using mice with special nanowire jackets to create power while running around in their exercise wheels.
But this is just the beginning. The jackets will be made "human" size. So you can generate electricity to run your iPod for example. Jackets will even be made to put on your dog. Taking a dog for a walk will no longer be a waste of human time.
The nanowire generators can be put on anything that moves or vibrates. They can be put on bicycles, cars, air conditioners, heaters and so on. It will take some time, however, to make them smaller and cheaper. Research on this is being done.

The Aim Is to Eradicate Polio
Smallpox was a serious problem in the 20th century. The World Health Organization declared in 1979 that smallpox was no longer a danger to the world's population. The aim has been to "silence" other diseases. It was hoped that polio could also be eradicated, but a stubborn region for this has remained in Pakistan. More cases were identified in Pakistan than in any other country in 2011.
The Edhi Foundation, a major charity, and the Pakistan government are working with the Global Polio Eradication Initiative to target the disease. Cases have fallen so that now Nigeria is the main trouble spot. There are fears that the progress could be short lived and figures could rise again.
Polio spreads far more easily than smallpox. The smallpox vaccine lasts for five years and is very effective. For the war on polio to be won, just about every person must be vaccinated. As the disease can only spread from person to person this goal must be achieved.

Those in Developing Countries Suffer More Depression
Only Western people get depressed due to their fast way of living - right? Unfortunately, this is not the case. Those in developing countries are also stressed as they struggle to survive. While Westerners do not have to worry too much about securing food, getting adequate sustenance for themselves and families is in many cases the main priority for the Third World population.
An examination of depression in developing countries by the University of Queensland on 480,000 subjects highlights this disturbing finding. People in Third World nations just do not go to doctors for treatment. The survey in 91 countries shows that stress is common across the board.
There is a fine line between depression and stress. Many would say they are the same thing. Anxiety was found to be higher in the USA with depression there being the lowest. Examining depression specifically, developing countries had more than twice the rate of the US - 9 per cent.
Political and military conflict was the main factor in causing depression. Getting correct data was the issue for researchers. Many surveyed didn't differentiate between anxiety and depression. They said they experienced mental suffering. If we in the West have difficulty in clearly defining stress and depression, it must be really challenging for those in developing countries.

Scientists Are Studying New Zealand's Extinct Moa Bird
Somehow they have worked out that wing feathers had speckled white tips. This was to camouflage the bird from predators. The very large Haast eagle once existed that preyed on them. It is claimed that because the plumage of other flightless NZ birds is dull with speckled tips this idea is valid.
The scientists plan to get feathers from the end of the quill and further down the quill to compare coloration. It is hoped the findings will enable researchers to correctly reconstruct life-like models of extinct birds.

Opioid Addiction Caused by Long Wait for Operation
The medical community has just noticed a fact that many have known for years - Waiting a long time for an operation can lead to opioid addiction. It is easy to get opiates from GPs just by telling them that you are in excruciating pain and an operation is a long way off. Shane Jackson president of the Tasmanian Pharmaceutical Society says money should be spent on more pain management specialist. This is a waste considering they only tell patients to take paracetamol that does not stop strong pain.
Setting up a data base will only lead to patients being denied opiates so they experience more pain and suffering. Blame the patients has always been easy to do. A data base will stop people getting morphine derivatives from all GPs. This creates an added problem. The solution is more medical staff and facilities to do more operations.
Reducing the risk of opiate addiction can be solved by denying patients access to such drugs, Though they may turn up in the hospital emergency department for an overdoes of paracetamol. When people are in serious pain rationality goes out the window. When the cause of a problem is obvious why do researchers take the shortest path to "sooth" the situation?

Synthetic Heart Repair Conduit
Treatment for heart disease is advancing at a rapid pace. Soon, a tiny piece of artery will be removed from a patient and a new heart conduit will be formed. This is for minor problems in the heart, less that 5mm wide.
Conduits are also being made from synthetic materials. Toleration of foreign substances is not a problems because it degrades quickly. They are used to go over the outside of a graft to stop bleeding. The synthetic conduits are made of a fine poly-(glycerol sebacate) net coated with polycaprolactone and the anticoagulant heparin. Mesh holes are too small for blood to pass through. Nothing of the implant remains after three months. A new structure of endogenous cells with M2 macrophages (which reduces inflammation) remains.
Though tests have only been done on rats, use in humans will probably be just as successful. Large grafts using the material will be done to see if this is feasible. This will be a welcome advance in medicine. A graft made of the body's own tissue will last much longer and patients will not need to be treated again for obstruction in the new graft.

Water is the Problem not Oil
We are obsessed with the oil crisis. So much so that we fail to see other problems that face us in the near future. For example, what about fresh drinking water. If nothing is done soon, the world will be in crisis. Even countries with cold climates, in Europe, are facing a shortage of potable water because of the high population density. As people become Westernized they consume more water. They change from bathing when they can, to having showers every day.
Production oil also impacts on the availability of water. it takes 2.5 liters of water to produce every liter of oil. Even growing bio fuels puts pressure on water, with a thousand liters of water needed to make a liter of bio fuel. The modern way of life is water "heavy":
Wealthy people use 3,000 liters of water each day to live their lives. More drought in the world is putting prices of everything up. When water gets short it does so locally. Moving water from one place to another in bulk is problematical. In the short term it is possible, but in the longer term it is not. Food production will fall behind what is needed over the next two decades if nothing is done.
The oil crisis and carbon pollution are problems but a shortage of water will hurt most of all.

Times Get Tougher for Sole Mothers
There is little sympathy for sole mothers from others in society or government. Social security payments have been tightened up by the federal Government. If sole mothers do not work they must go back to school, probably learning something that is useless for their future.
Not many full-time workers have brought up children as well without paying someone else to care for their babies and toddlers. Older children are consistently being left alone as mothers do some sort of part-time work. This is reality. Part-time jobs do not pay well enough to provide money for carers. When Single mothers come home they not only look after their children, they must do all the household chores as well as do repair work to the home.
The government's new harsher policy comes into force next January. Welfare payments will fall. Even those working part-time will lose some of the part-payment they get from social security. Children will be the real losers as food and heating/cooling are reduced. As the number of sole parents below the poverty line increases from 10 per cent to 20 per cent, things will be tough. The loss of $40 a week from next year for those fully reliant on welfare payments is a massive amount. Two thousand dollars a year is a significant fall in income.

Views on Climate Change Has Altered in the US
The common view on climate change (CC) has shifted. This is due to the shocking weather in the US over the last few years. A survey of respondents at Yale University shows those who believe that global warming is happening has increased from 57 per cent in 2010 to 66 per cent currently.
People with common views have been identified:
People with common views have been identified:
- Alarmed - 13%
- Concerned - 26%
- Cautious - 29%
- Dismissive - 10%
- Disengaged - 6%
- Doubtful - 15%
These figures were obtained in 2011, a year before the Yale study which noted the changes as follows:
- Alarmed - 13%
- Concerned - 26%
- Cautious - 34%
- Dismissive - 10%
- Disengaged - 2%
- Doubtful - 15%
Other important opinions in each group include:
- Alarmed - 57% = Extremely sure CC is happening
- Dismissive - 94% = Strongly dstrust Pres. Obama
- ........"....- 70% = Strongly distrust climate scientists
- All Respondents - 58% = US could afford to act on CC
- ........"..........- 79% = Solar & wind power are answers
People have to directly "live" dramatic change in weather for their view to alter. This is the experience in the US and it is probably the same elsewhere. As bad weather occurrences become permanent the global common opinion will be that damage has been done to the world's climate by human activity.

Vaccinate All Cattle to Stop Food Poisoning?
Why bother to be hygienic. We can feed cattle all sorts of filthy stuff, and when we eat it we still remain fit and healthy. This is the message being sent by the president of company Bioniche. In order to promote his new product the president is making dramatic claims. Cattle can all be vaccinated against e.coli, can eat anything and wander around in rubbish, apparently. Such is Mr Rick Culbert's faith in the success rate of his product.
The e.coli "bug" lives in all of us both humans and animals. Only dangerous species make us sick. This vaccine will kill all e.coli in the body. Wait a minute! Don't antibiotics kill useful flora in the gut, so we must not take them regularly? What happens to a cow with no e.coli in its system is unknown. Eating such "clean" meat could be dangerous to our health.
Outbreaks of food poisoning occur in every country. The fight for cleanliness in food handling must continue. If beef is guaranteed free of e.coli wouldn't butchers have less pressure to work in a sterile environment? Radiating ingredients in manufactured goods is widespread now. There is a cost. Buy a frozen pizza from a supermarket. Take it home and put it in the oven. It looks great. The tomato is a nice bright red color, the cheese looks appetizing, but everything tastes the same. It tastes just like cardboard.

Tree Grows Inside a Man
A man had severe pains in his chest and began coughing up blood. Doctor Vladimir Kamashev x-rayed the man's chest and had a big shock. He had to call his assistant for a second opinion. The assistant confirmed the doctor's diagnosis. The man had a fir tree growing inside him.
Fungus can grow inside a human body but it was not believed that plants could take root and grow there. Surgeons removed a young five-centimeter fir tree from the man's chest. Needles from the plant dug into the capillaries and caused bleeding. The man consequently coughed up blood.
Obviously a small "cutting" from a fir tree was inhaled. It found sustenance inside body tissue. What is surprising is that a biopsy of the plant showed the fir needles to be green, so the tree somehow got enough sunlight to survive. Parts of the plant have been preserved for further study.

Rain Forest in Northern Australia Doing Well
The northern part of Australia is getting hotter, but it is no drier. A comparison of data from the 1950s and the present shows the borders between rain forest and eucalyptus forest remained the same. However, the density of rain forest increased by 732 ha. Neither drainage, geology, topography, aspect or elevation are responsible. The climate has definitely changed. Despite a series of El Nino dry spells since the 1950s, the country is becoming wetter.
This rain forest expansion has slowed over the last 2000 years, with 25 per cent being tall open forest. Eucalyptus forests are spread out in irregular shaped pockets which are very stable. Higher CO2 is responsible for the increasing density of rain forest. The humidity keeps damage from fires low.
Overall, this is good news for the world generally. Brazilian rain forest stores 250-300 C ha–1 (carbon per hectare). Though Australian rain forest stores less, it is still significant. There is a possibility that local factors in Australia are having this effect. Yet indicators do point to global warming.

Windows 8 Crashes
THE END OF THE ROAD FOR EASY WEB DESIGN
Windows 8 means more problems for web page designers. What Internet Explorer reproduces in Windows 8 on a personal computer is not what comes out on a tablet. Internet Explorer 10 is the worst culprit. Having IE10 built into Windows 8 with no possibility of going back to IE9 is a nuisance. Text goes right off the background square. On a PC, fonts are either extended too long and go over the background square at the bottom, or there is a line gap under the full stop because text is too short.
Nearly all the other browsers reproduce correctly, except FireFox with the last word on some fonts extending to the next line. This is rare though. Obviously, the problem lies in the operating system itself which is designed specifically for tablets. Personal computers are only of secondary consideration.
There is a "war" going on in the US at the moment over how images will be shown on tablets and even mobile phones. The powers that be are in a battle with professional code writers over what system will be used. This wonderful image system is called Picture Fill. The font problem with Windows 8 will make the fight more complex.
Designers will now have to put images onto a web page knowing that in some circumstances fonts may write over the image or go behind it. Windows 8 is being released far too early. It is not yet known whether the new coding will be in HTML5 or left for HTML6. Whichever way it goes Windows 8 will be obsolete.
The new code for Picture Fill put forward by designers has four images being uploaded to the server at four different pixel densities. This is for each image on the web page. The lowest size and pixel strength will be downloaded by small devices. High definition sites on personal computers will download the highest definition image version. This will definitely make download times longer for all systems, and take up more memory on servers.
Your $40 will be wasted on upgrading to Windows 8. The problems are countless. You cannot set up a network in your home because security turns off and prevents access to Windows Firewall. This blocks all attempts at accessing other devices. Many older versions of software keep shutting down despite compatibility settings. You have to give Microsoft your email address and your correct password as you are logged on at startup. They are surely going to look at your email
Stay with Windows 7. It is the last Windows system written exclusively for PCs.

Scientists studying the disease now believe it should be reclassified as a parasite. Though at first glance it seems to be a cancer it has many characteristics of a parasite.
The parasitic cancer stays in a host until the sufferer is irretrievably damaged then it will move on to a new host. It uses the Tasmanian devils predilection for violence to spread itself. It remains alive by sticking to the teeth. When devils fight they snap at each others' mouths causing blood to flow.
It is really a new category of disease. Though a cancer it not in other animals. A parasite will exist in many animals. The disease originated in one female devil during the 1990s. Just how it originated is not known. It is such a difficult disease to treat. The Tasmanian devil could reach its demise in less than 15 years.

Science
Alien predators are the main danger to the survival of Australia's native wildlife. Foxes and cats are clearing many areas of native animals. Indeed, Australian fauna has been the hardest hit in the world. Bettongs (rat-kangaroo) and wombats for example are oblivious to the danger when a cat or fox is present.
Australian prey have developed camouflage to defend themselves from native predators, but alien predators can see through this.
Thousands of years of isolation have made native fauna vulnerable. Other continents have long had the cat, goat, grey squirrel, mouse, pig, rabbit, red deer, red fox and ship rat, so their native animals have learned to survive and avoid extinction. Responsibility lies clearly with early European immigrants. The damage was done a few hundred years ago.

Astonuats Take Cover from Solar Storms - Better Predictions
The state of the weather is a problem on Earth with predictions not always being correct. In space, however, there is a more serious weather problem. Solar storms can kill. Detectors at the South Pole measure neutrons. When the level reaches a certain point astronauts on the International Space Station shelter in a shielded capsule.
Advances have been made in predicting solar storms which can destroy satellites. Unfortunately, little can be done to protect them, but the safety of astronauts is paramount.
Storms move at different speeds. The faster the speed the more energy in particles, which makes them more intense and dangerous. Ironically, because there are more low-energy particles in a solar storm they do most overall damage. The early arrival of these low-energy particles does forewarn the onslaught of the high-energy neutrons.
The number of solar flares gives an indication of future activity, though this is only a possibility at best. Neutron sensors at the South Pole measure neutrons emitted when particles slam into atomic nuclei of gases in the Earth"s upper atmosphere.

New Cancer Drug Announced in Melbourne
A new cancer drug has been announced by Cancer Therapeutics CRC in Melbourne. CTx-294886 is to be used in conjunction with another medication, Avastin. Furthermore, a new type of scanning has been developed by the same company. It will identify protein homeostasis, a new pathway in cancer treatment.
CTx-0294886 stops tumour growth by inhibiting Focal Adhesion Kinase (FAK) and Vascular Endothelial Growth Factor Receptor 3 (VEGFR3). This with Avastin reduces angiogenesis, slowing tumor growth in breast cancer. Examination of effects in head, neck and cervical cancers is ongoing.
The company has already developed a primary anti-cancer medication, CTx-294945). Both drugs can now be used to prolong life when dancer is detected. Research was done with the assistance of Australian and international institutions.

Mysterious Circles in Africa
Bare circles of earth ringed with tall grass are found all over Africa. They have been a mystery with all kinds of stories told about them. Now a partial explanation has been found. Walter Tschinkel has been studying the phenomenon since 2005. At first he thought they were caused by termites which poisoned and killed off the grass. He realized his mistake when he analyzed satellite images - the circles were alive!
The circles would disappear then appear somewhere else. However, for the most part circles remain in one place for up to 75 years. The average life was 41 years. Rain tends to be the main factor leading to formation of a new circle. Tschinkel has not discovered the real cause. If fertile earth is put inside a circle grass still will not grow. Something is going on in a chemical or "living" sense.
Locals do not want the mystery solved. They make a living out of them. For a fee tourists "adopt" a circle, then keep up-to-date by viewing it on Google Earth. There is a real fascination for them. Like the crop circles elsewhere in the world human intervention cannot be ruled out, but the mystery continues as Walter Tschinkel works hard on his chosen project.

Staying Out of the Sun Prevents Skin Cancer but Not Osteoporosis
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. Even exercise is questionable, as this could cause bone fractures in susceptible people. Bone density tests just show that someone already has the disease.
