Travel

Cambodia and Vietnam

 

 

 In April 2010 we travelled to the previous French territories of Cambodia and Vietnam: ‘French Indochina’, as they had been called when I started school; until 1954. Since then many things have changed.  But of course, this has been a region of change for tens of thousands of years. Our trip ‘filled in’ areas of the map between our previous trips to India and China and did not disappoint.  There is certainly a sense in which Indochina is a blend of China and India; with differences tangential to both. Both have recovered from recent conflicts of which there is still evidence everywhere, like the smell of gunpowder after fireworks.

More on Technology and Evolution

 

 

 

 

Regular readers will know that I have an artificial heart valve.  Indeed many people have implanted prosthesis, from metal joints or tooth fillings to heart pacemakers and implanted cochlear hearing aides, or just eye glasses or dentures.   Some are kept alive by drugs.  All of these are ways in which our individual survival has become progressively more dependent on technology.  So that should it fail many would suffer.  Indeed some today feel bereft without their mobile phone that now substitutes for skills, like simple mathematics, that people once had to have themselves.  But while we may be increasingly transformed by tools and implants, the underlying genes, conferred by reproduction, remain human.

The possibility of accelerated genetic evolution through technology was brought nearer last week when, on 28 November 2018, a young scientist, He Jiankui, announced, at the Second International Summit on Human Genome Editing in Hong Kong, that he had successfully used the powerful gene-editing tool CRISPR to edit a gene in several children.

The Fukushima Nuclear Crisis

 

 

Japan has 55 nuclear reactors at 19 sites.  Two more are under construction and another twelve are in the advanced planning stage.  Net Generating capacity is around 50 GW providing around 30% of the country's electricity (more here).  

As a result of Japan’s largest earthquake in history on March 11 and subsequent tsunami all reactors shut down automatically as they were designed to do but cooling systems associated with two sites had been damaged. 

Three reactor sites are adjacent to the earthquake epicentre and two were in the direct path of the tsunami.  The Fukushima-Daiichi plant belonging to Tokyo Electric Power Company was particularly hard hit.  It lost all grid connections, providing electricity, and its backup power plant was seriously damaged.
