Progress in life extension science and technology.

Gene Therapy Advances

Three interesting advances in gene therapy have recently been reported. The first reports gold nano particles to deliver gene therapy directly to skin cells, simply by including them in commercial moisturising cream. This particular therapy uses siRNA to specifically target … Continue reading

Quantum Time

The article “Freezing Time” published in The Scientist describes the development of extremely powerful enzyme inhibitors. Because of their vastly higher affinity for the enzyme, they can not only be used in much smaller doses for medical purposes, but persist for … Continue reading

Get A Brain

Life extension by using stem cells or cybernetics to fix or replace organs is all very well, but it doesn’t help us if our brain decays. Our memory of who we are and the processes that result in our consciousness … Continue reading

Life Extension Progress

Two recent advances have brought life extension closer to reality. First, on the cloning front, scientists have finally succeeded in generating viable human embryonic stem cells from cloned cells (nuclear transfer). There is a way to go yet as the … Continue reading

A Small World

Scientists have developed the technology to analyse gene expression in hundreds of individual cells in parallel. Technical details: it uses microfluidic devices to integrate single-cell processing and RT-PCR (reverse transcriptase-polymerase chain reaction). Dr. Hansen foresees the technology will have widespread applciations … Continue reading

Stem Cell Victory

Good news on the stem cell front, a US judge has finally ruled that federal funding for research with human embryonic stem cells (hESC) is legal. Two scientists, of all people, had sued on the grounds that funding the research … Continue reading

First Stem-Cell-Organ Transplant

Well, it’s just a tooth, but a tooth is actually a complex organ and it is an exciting first for scientists to have implanted a tooth made from stem cells into a mouse, where it integrated, survived and functioned pretty … Continue reading

Lifewatch: Gene Editing

One of the problems with curing genetic diseases by genetic engineering is that the easiest method is randomly inserting the correct gene. But then you not only don’t take advantage of the natural gene function regulators, but you run the … Continue reading

Smooth Joints

One of the many issues of growing old is the slow deterioration in cartilage. Cartilage provides a “non-stick” surface to lubricate your joints, and while it is a remarkable material (often lasts a lifetime of wear!), it has little if … Continue reading

Heart to Heart

A paper in Nature, summarised in The Scientist, reports success in making progenitor cells, that naturally exist in the outer layer of heart tissue, proliferate, migrate into heart muscle and transform into heart muscle cells (cardiomyocytes). The research in mice “suggests … Continue reading
