Scientists in London Develop Pain-Free Filling That Allows Teeth to Repair Themselves Without Drilling or Injection


(The Guardian) A tooth-rebuilding technique developed at King's College London does away with fillings and instead encourages teeth to repair themselves.

Tooth decay is normally removed by drilling, after which the cavity is filled with a material such as amalgam or composite resin.

The new treatment, called Electrically Accelerated and Enhanced Remineralisation (EAER), accelerates the natural movement of calcium and phosphate minerals into the damaged tooth.

A two-step process first prepares the damaged area of enamel, then uses a tiny electric current to push minerals into the repair site. It could be available within three years.

Britain’s first ‘Bio-Bus’ powered entirely by human and food waste takes to the streets

(The Guardian) Britain’s first ‘poo bus’ will take to the road on Thursday, powered entirely by human and food waste.

The 40-seat “Bio-Bus” runs on biomethane gas, generated through the treatment of sewage and food waste. It can travel up to 186 miles on one tank of gas, which takes the annual waste of around five people to produce.

The bus is run by Bath Bus Company and will transport passengers between Bath and Bristol Airport.
