Lung Disease Healed by Stem Cells

Stem cells are magical in the things they can do. Just about every ailment they are aimed at succumbs to them. It could be that in the future it will be the most-used method of treatment.  There is a case for fast-tracking treatment to help those with chronic illnesses.
chronic obstructive pulmonary disease copd
Two patients with chronic obstructive pulmonary disease were injected with adult stem cells. After only a month they improved. A study of nine people also having the condition were given stem cells taken from bone marrow. Inflammation was reduced significantly.

There has not been any method of treatment for COPD until the use of stem cells came to the fore. It is estimated that nearly 15 per cent of Australians over 40 have the disease.  This is incredibly high and hard to believe.

The major symptom is difficulty breathing. A reduction in inflammation improves lung function. Dr Moodley who announced the research findings said the treatment could save governments millions of dollars. It seems odd that a physician's main priority is economic rather than patient welfare!

Forcing STEM Graduates to the Bush Will Not Work

The number of school students doing maths and science is woefully inadequate in city areas. Numbers in rural areas are even worse! A new plan is in progress to improve the situation. Unfortunately, it will prove to be a total failure and waste of money.

Culture has inertia. It takes about half a century to alter established beliefs. Rural children believe that maths and science are too difficult for them so they do not even attempt them. They stay with the social subjects. The new "curative" program to solve the matter will ignore city students and concentrate on rural regions.
Students in a rural bush outback school teacher teaching
There is a noticeably low number of rural students doing education, engineering and science degrees.  Note that 74 per cent of teachers in city areas have STEM experience, while only 17 per cent of rural teachers have done STEM work.  The intention is to send high quality STEM (Science, Technology, Engineering and Math) teachers to the bush - they will love that! It is like sending the trainer of the winner of the Melbourne Cup to train horse riders in the sticks, an absolute waste of resources.

Advanced teachers are not the answer. Those who can teach the basics are needed because going with the horse analogy, getting over the first jump is the most difficult problem. If students get this achievement they will at least choose base maths. Australia has the silliest curriculum with up to five levels of maths. When I was young we all did the same compulsory arithmetic then maths. Arithmetic has been forgotten. Bureaucrats do not see that this subject is the foundation for all math.

State schemes such as "go to" the bush for an annual $10,000 check have not worked. Teach For Australia is going to forcibly place graduates in rural schools. The experience will be part of their career training. We will see what teachers unions have to say about this. They will not accept it lying down.

To willingly draw skilled young teachers to rural schools will take money and lots of it. The federal government is cutting back payments to states. And states are running deficits. Forcing movement to the bush where even basic services are not available like a decent water supply and courier deliveries, by making rules to achieve it, will not work. City born, city live is the motto of young people.

Zebrafish Stem Cell Discovery

A lot of work is going into stem cells research. Anything we can learn about them is important for future human transplants. There have been some claims that have been proved wrong. However, we are moving forward in understanding how organs can be created from them.

A significant breakthrough has been made in Australia while investigating zebrafish. Scientists have found out how hematopoietic stem cells (HSC) important in bone marrow and blood are made. The stem cells replenish immune cells in the blood.

At present hematopoietic stem cells are used to treat leukemia and myeloma. It will probably be possible to treat other cancers in blood vessels, muscle and bone. Furthermore, diabetes, spinal problems and degenerative disorders cold also be treated.

The discovery is important. "Buddy" cells were observed while the hematopoietic stem cell were being created. Ironically, the scientists were investigating muscle development when they noticed the "helper" cell. Other scientist will take this further.
