The Sum Of Its Parts

Two years ago I bought a new car, not a second hand vehicle as is the norm in New Zealand, but a genuinely new European car.  It came with its usual Teutonic pedigree and a guarantee that it would perform without problem.

Two days ago, the small plastic grab handle for the driver's seat adjustment gave into the strain with a loud crack, propelling me backwards and leaving me with a handful of plastic shards.

Why was this so mortifying? Firstly the factor of the unexpected release which propelled me backwards into my seat. Secondly was the growing realisation that the part in question was grossly inadequate for the purpose to which it was put.

A thickness of two or three millimetres of plastic was never going to last the distance and so it proved.  What to do?

Fortunately a new car comes with a warranty and in the case of our model this was for three years.   So I dutifully made a temporary repair with a bandage of used rubber bands and called the dealer.

It is here that I must give kudos to the Service Manager of my local franchise.  Often the term "service" in a title means anything but.  In this case he couldn't have been more obliging, agreeing that the offending plastic was inadequately designed for the job, and giving me a replacement free of charge.

To be frank I would much prefer to travel by public transport as I did in Singapore.  Yes, there has been the occasional and frustrating MRT failure in recent times but at least there is an MRT to fail!

Now come the news that Singapore and KL are going to be linked by a high speed train.  The planned service includes stops in Johor, Malacca and Negeri Sembilan.  Pity there is no stop mooted for Ipoh; giving passengers the chance to stock up on some of their famous kueh kueh.

Do I Smell A Plastic Rat?

Coming up for air?
I am not quite sure how I should react to the news that Caltech and Harvard University scientists in the US have bioengineered a "jellyfish" that can swim.

The 'creature' is made up of silicone polymers and rat heart cells.  That's a plastic ratus ratus to you and me. But unlike the often maligned Gunther Von Hagens variety, these plasticised animals actually have a life, but to paraphrase Star Trek, "Not as we know it".



The Medusoid, for that is its name, is designed to be a biological pump and to assist with heart surgery. 

The process according to my local newspaper, was to use a sheet of cultured rat heart muscle which contracts when electrically stimulated in a liquid environment.  It is the perfect raw material to create the jellyfish according to the researchers..

A silicone polymer was then used to fashion the sheet into a thin membrane that resembles a small jellyfish, with eight arm-like appendages.

Medusoid was then placed in container of salt water and shocked into swimming with synchronised muscle contractions that mimic those of real jellyfish

Kevin Kit Parker who was the project's bio-engineer has quipped that "The world needs less rats and more jellyfish, so I thought it would be cool to do a one-for-one swap".

Now he has his sights set on a different and larger animal to mimic using these processes -  perhaps a politician with a plastic brain or a banker with a plastic heart?  

Come to think of it, my banker already has one.
