Aussie Bird Flies a Long Way

An Australian bird has flown a long way. Scientists were studying birds on the shores of western Alaska in the Arctic. They saw a bartailed godwit and examined the bird believing it to be a local inhabitant. The tag on its leg, however, showed that it had flown a very long way. Australian scientists had banded the bird earlier in Victoria. The small creature had travelled more than 8,000 miles.

Studies had shown that bartailed godwits usually spend their life in the same local area where they were born, though many presumed that they flew to the Arctic to breed. This has now been substantiated by the discovery. It is known that banded dunlin and semipalmated sandpipers fly to the Arctic from Asia and South America.

With the Arctic thawing, damage could be done to future breeding populations of birds. The hotter Arctic summer could affect the survival of the young. Migratory shorebirds are decreasing in number. This is due, it is believed, to habitat loss and global warming. More research is required in order to identify specific causes.

The Way You Feel Affects Surgery Recovery Time

The way you feel about yourself and the social environment in general can affect the time taken to recover from surgery. Few tests have really proven this to be fact, however. Existing data were re-examined in an attempt to find a correlation. Relationships were indeed found

Depression, anger, anxiety, sadness, loneliness and intramarital tension certainly do not help recovery. Strong religious belief and optimism reduced pain improving healing time. Learning relaxation techniques also helped, as did interaction with a psychiatrist.

Though the data points to affects on recovery times, strong correlations were not found. This is rather perplexing. Common sense would indicate improved outcomes with positive outlooks. For the present, medical practitioners will have to accept that the way one feels affects healing without relying too heavily on the findings.

Dogs of Non-restricted Breeds Also Bite

Western Australia reacted to attacks by dogs on children. A few years ago legislation was passed to not only muzzle but also sterilize American Pit Bulls, Mastiffs and Japaneses Tosas.

Since then there has not been a major decline in the numbers of these breeds. The legislation has not worked out as intended. President of the RSPCA, Hugh Wirth, says breeding of "dangerous" dogs has gone underground.

Dr Kersti Seksei of the Australian Veterinary Association (AVA) makes the point that dogs of any breed can and do bite people. It is usually the case that household pets bite members of the family. The AVA suggests testing of dog temperament when they are sold. This would be difficult to police because most cross breed puppies are sold privately.

Dogs follow their owners' behavior. Dangerous dogs are created, not born. That is why police dogs are always muzzled in public: they are trained to be dangerous.

Less Atractive Males Make do With Plainer Females

An audience affects the behavior of mating male fish. If a male Atlantic Molly (Poecilia mexicana) is left alone he will try to mate with the healthiest looking female - the best female in his eyes. If there are other males in the vicinity he will not choose this female.

It may be thought that he is giving up. This is not the case. He is thinking strategically. By choosing a less desirable female he leads other males away from the intended target best female. The male hopes to mate with this female later when the other rival males have gone.

Some males are just too ordinary and have to mate with lesser females because other fitter males stop them getting close to "ideal" females. Mating with any female is better than not mating at all.

This behavior could be present in humans. When a group of young men meet with a group of young females the handsomest men can be expected to pair off with the prettiest young ladies. The less attractive have to make do with second best. This means that some of the good genes carried by the plainer individuals can be passed on despite mating between the healthier, fitter thus better looking people being the norm.

More Meat and Milk from Cloned Cows

The Pollard farm looks like an ordinary farm but there is something that makes it unique. Many cows there are identical. Indeed, 20 are clones. They are copies of the most productive animals around. It must be noted, however, that the clones real age is their actual age plus the age of the animal they were cloned from. This is the problem with cloning, but, in breeding animals that give more meat and milk there has been no major obstacles.

Less feed is required per pound of meat or liter of milk. Clones also reproduce quicker with reduced complications. This is good for the environment: less fertilizer and diesel is used.

There are issues with genetic tampering of animals and crops. Scientists are saying that despite decades of work no genetically modified crop has yet been adopted worldwide. Because only people from high-income countries eat meat, cloning of cows will not help world hunger.

The real challenge with cloning of cows is the high cost - $15,000 per animal. So meat from them will also be expensive. Genetically modified crops also have the same problem. Thus, cost is the main persisting barrier to acceptance of GM products.

Problems in the Cattle Yard

There are problems in the cattle yard due a non-caring board. Richard Ogilve was voted off the Herefords Australia Limited (HAL) board. This infuriated members of the society because they believe Mr Ogilvie is the only one who knows what they want.

Richard Ogilvie owns a 5,000 strong cow herd in Millicent, South Australia. He says 10,000 of HAL members will leave and form their own association. This is nearly half the total membership of HAL.

Present members are upset by the board arguing political differences and passing time by running cattle shows, not concentrating on improving the Hereford industry. The industry for Angus cattle is booming. Many feel the Hereford market is not being managed properly. Mr Ogilvie is seen as a strong leader who can improve matters for Hereford breeders.

This is another case of those at the top fighting each other and concentrating on irrelevant issues while not doing what they are paid to do.

The Tax Working Group Makes Predictable Recommendations

The Tax Working Group (TWG) has reached the conclusion that there should be a corporate tax cut. This finding was not surprising considering it was set up for this purpose. It is said that this will bring more investment money into Australia. Considering the Australia currency is already far too strong and is slowing down exports because they are too expensive on the world market, the last thing we need is more money flowing in.

This can be funded by reducing tax offsets for R&D development, it says. What a silly idea this is. Reduce R&D and we will have nothing new to sell. This is like robbing Peter to pay Paul. These are the same companies who will enjoy the corporate tax cut. By cutting back on gas, oil, agriculture and transport tax write offs, there will no overall benefit. Furthermore, ending tax deductions for multinationals will slow foreign investment not improve it.

These inquiries are often a waste of public money. They make recommendations that are usually only the "moving of furniture around the room". Nothing fresh and forward looking is ever suggested by them. The TWG even says the government will collect more revenue by these changes, so it can lower the general tax rate. Great, everyone pays less tax.

What a wonderful state of affairs this will be. Of course, we will pay the "same" tax to government, whether it is direct tax or indirect tax. The TWG are in dreamland.

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

It seems we can study what animals looked like even though they are extinct. Australian and New Zealand scientists are studying prehistoric feathers to find out what birds were like. DNA has been obtained from the extinct Moa bird of New Zealand from feathers 2,500 years old. Moa are thought to have been still alive 1200 years ago It was 8 feet tall and could not fly. Material has been gleaned from three types of Moa: the stout legged; the heavy footed; and the upland Moa.

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:

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.
