Nanowires fashioned into billions of transistors on a microchip could someday drive tiny, ultra-fast computers.
If we need to microchip dangerous dogs, so be it.
The tiny microchip , thinner than a human hair, will initially be used in patients suffering from eye diseases, potentially saving the sight of thousands of people.
But now, scientists have developed a way to make the materials for genes on a microchip in mass quantities, for a fraction of the current cost.
It is a simple procedure whereby a tiny microchip , about the size of a grain of rice, is inserted under the skin of your pet's shoulder blades by a vet.
These days we microchip our pets so that they can be tracked and brought swiftly to justice.
It is inserted in a microchip on which the research engineers have also integrated most of the evaluation electronics.
Permanently identify your dog - although the law states a dog must wear a collar and tag, these can get lost or taken off and it is advisable to microchip your pet.
A licence is only £5 a year and then to tag or microchip your dog doesn't cost much either.
The next issue I wish to talk about is the proposal to microchip dogs.
