A made-in-Singapore solution to the world's plastic waste problem

These scientists from the National University of Singapore and the Singapore Institute of Manufacturing Technology have converted polyethylene terephthalate (PET) bottles into a highly insulating and absorbent material called aerogel.

Aerogels, the lightest and most porous materials known to man, have existed since the 1930s – and were used to insulate the Mars Pathfinder rover in the 1990s.


And with an estimated eight million tonnes of plastic waste entering the world’s oceans each year, there is no shortage of material that could be recycled into aerogel products instead.

Their possible real-life applications include:
  • As a lining for fire-retardant coats and carbon dioxide absorption masks that could be used during a fire; 
  • better heat and sound insulation in buildings; and 
  • cleaning oil spills.

Scientists discover prostates can be shrunk with direct injections of alcohol


Injecting alcohol directly into the prostate gland could shrink it and avoid the need for men to get up in the night to urinate, a study has claimed.

Ethanol jabs through the rectum shrink the prostate by more than a third and relieve pressure on the bladder and penis.

Doctors said the development is 'excellent news' and believe it could be as effective as treatments already used by the NHS.

The common mistakes we ALL make when it comes to brushing our teeth


Dr Mark Hughes, a Harley Street dentist and ambassador for FOREO explained how to improve your daily brushing routine.
  • Never rinse after brushing - give time for toothpaste ingredients (like fluoride) to be absorbed
  • Ditch the mouthwash - alcohol from mouthwash will dry the inside of your mouth, causing bacterial growth
  • Clean your tongue too
  • Avoid tooth care fads - like charcoal toothpaste which is extremely abrasive to your teeth
  • Avoid certain food like coffee and white wine, which will stain your teeth.

Are you at risk of 'selfie wrist'?

Taking too many selfies could leave you with a painful nerve condition, a California doctor is warning.

The digital age's latest hazard has been dubbed 'selfie wrist', a numbing and tingling sensation experienced in the wrist and fingers.

Dr Levi Harrison, an orthopedic surgeon based in San Francisco, told KABC News he is seeing a rise in patients with the condition, which he describes as a form of carpal tunnel syndrome.
