Attending to New Technology Safety Issues Sunday, February 28th, 2010

“It’s important for Australia to take advantage of new technologies as they arise,” said an Australia government industry department spokesman. “… it’s very important that this isn’t done to the exclusion of health, safety and the environment.”

This is the philosopy behind the National Enabling Technologies Strategy released by Australia government on February, 22 this year. A Stakeholder Advisory Council with representatives from trade unions, and consumer and environment groups will be established under the strategy.

Technologies such as nanotechnology and biotechnology have given rise to numerous controversies and the government wants to listen to all the diverse views. There are differing views on the ethical, environmental, health and other implications of new developments in these technologies.

A danger of nanotechnology is the possibility of unregulated exposure of workers to nanomaterials that act like asbestos fibers and cause serious health problems. At nanosizes, materials often exhibit properties very different from normal state. Completely safe materials can become toxic when reduced to nanosizes.

Nanotechnology is not the only new technology that poses such dangers. For example, in biotechnology there is resistance against genetically modified food crops on the grounds of unproven safety and destruction of bio-diversity. Bio-diversity is critical for the long-term health of our planet and ourselves.

A union spokesman felt that “It’s a case where the technology is running way ahead of the regulation.”

The strategy has not fully satisfied all the groups.

Stem Cell Treatment for Lou Gehrig’s Disease Sunday, February 28th, 2010

Stem cell treatment includes taking a patient’s own cells from bone marrow and developing them into specialized cells such as nerve cells in the laboratory, for injecting back into the patient. Scientists hope to find cures for diseases like Alzheimer’s using this approach.

A report from Israel mentions about a clinical research agreement for Lou Gehrig’s Disease between Hadassah Medical Organization and biotechnology firm BrainStorm. Hadassah will make its top experts in neurology and stem cell research at the disposal of BrainStorm, which will invest NIS 5 million into the research effort.

Amyotrophic lateral sclerosis (ALS) leads to progressive degeneration of motor neurons, the nerve cells in the central nervous system that control voluntary muscle movements. It has come to be known in North America as Lou Gehrig’s disease. Gehrig was a New York Yankee’s baseball icon who died from the disease in 1941 at age 37.

The world-renowned sceintist Stephen Hawking is a victim of the disease, illustrating how a brilliant mind can reside in a wasted body and still continue to function with its full power. In certain cases, ALS can affect cognitive functions also.

The Israeli scientists hope to prove that the proposed treatment can slow down or even halt the progress of ALS in victims. Success can help BrainStorm to tap a billion dollar market.
