Resetting The Clock: New Enzyme Found To Repair Telomeres

Posted by in categories: biotech/medical, life extension

Resetting Your Biological Clock: New Enzyme Found To Repair Telomeres.

The telomere caps on the end of your chromosomes unravel bit by bit with every cell division, and if they’re not repaired division eventually stops altogether. Cells like stem cells express special enzymes to lengthen these caps, and we’ve now found another one that does the job.

A key player in aging?

Uncovering the secret of turning back time

Posted by in categories: biotech/medical, engineering, genetics, life extension

I had read about Singapore in genetic engineering way back in the 90’s. I think they were 1st or 2nd in making immortal skin cells at the time.


Singapore scientists have unravelled a mystery that could pave the way for turning back the clock on ageing.

A recent study led by Dr Ng Shyh Chang of the Genome Institute of Singapore at the Agency for Science, Technology and Research (A*Star) has found a gene in human egg cells that suppresses an enzyme causing cells to age.

Genome Editing with CRISPR-Cas9

Posted by in categories: biotech/medical, genetics, neuroscience

This animation depicts the CRISPR-Cas9 method for genome editing – a powerful new technology with many applications in biomedical research, including the potential to treat human genetic disease. Feng Zhang, a leader in the development of this technology, is a faculty member at MIT, an investigator at the McGovern Institute for Brain Research, and a core member of the Broad Institute. Further information can be found on Prof. Zhang’s website at http://zlab.mit.edu.

Using Ultrasound To Pierce The Blood-Brain Barrier

Posted by in categories: biotech/medical, neuroscience

Treating the brain often requires invasive surgery, but a new technique involving ultrasound and air bubbles has now shown promise at delivering drugs through the blood-brain barrier.

One of the biggest challenges of medicating brain tumours is actually getting drugs into the organ. Your brain is well protected from invasion by untoward substances or life forms, and this protection limits what will enter from the bloodstream. There have been previous efforts to open up the barrier, but they often involve a surgical approach that is far from ideal.

Legalization of Drugs Should Be Part of a Transhumanist Agenda

New article for Vice Motherboard on why society should support legalization of all drugs–and a short video of the Immortality Bus in Arkansas talking to marijuana supporters (a state where it’s totally illegal):

Undoing Sugar Damage: First Synthesis Of Culprit Glucosepane

Posted by in category: biotech/medical

Sugars may taste divine, but they’re also highly reactive molecules that progressively stiffen your body in a process called glycation. Scientists have now synthesised the primary molecule formed in glycation for the first time, leading to hope that drugs can be designed to break them apart.

What is glycation?

In our bodies sugars continuously react with proteins in an unregulated manner in a process known as glycation. This leads to the formation of abnormal chemical modifications of the protein which may impair its normal function. These sugar-modifications are collectively known as advanced glycation end products (AGEs) and can be subdivided in two main categories. First are the modifications that affect a single amino acid. The second category consists of modifications that link two amino acids together in a structure called a crosslink.

Scientists have found a way to 3D-print embryonic stem cell ‘building blocks’

Posted by in categories: 3D printing, biotech/medical

Pluripotent cells are great, but they can be difficult to steer into growing the way you want. Now scientists have found a new way to create 3D-printed ‘building blocks’ of embryonic stem cells (ESCs), which could be used for growing micro-organs, performing tissue regeneration experiments, testing medication and other biology research purposes.

While bioprinting with ESCs is not entirely new, until recently researchers have only managed to produce two-dimensional sheets of cells. Now a team of scientists from Tsingua University in China and Drexel University in Philadelphia have published a study in Biofabrication, introducing a novel technique for printing a grid-like 3D structure laden with stem cells.

In normal biological conditions ESCs naturally tend to cluster together into spherical ‘embryoid bodies’ – clumps of pluripotent cells which can go on to develop into any type of cell or tissue in the human body.
