Bone up Medical research
Printing your own bone may sound like science fiction, but researchers have managed to do just that with the aid of a printer originally designed to make 3-D metal objects. They fed bone-like ceramic powder into the printer, which was then programmed to produce a tiny scaffold the size of a pencil rubber. Lab tests on immature bone cells found that new bone started to grow over the scaffold within just a week. The researchers hope that one day these scaffolds could be used to treat orthopaedic and dental problems.
Remember licorice wood?
Chewing on a dried liquorice root may help in the fight against gum disease and tooth decay because it contains antibacterial compounds, say German researchers.
Red flag day
Your GP could soon be able to assess your risk of several different cancers with the aid of a tool embedded in their computer system. It enables doctors to spot ‘red flags’ (warning signals), alerting them to early signs of difficult-to-diagnose cancers, such as pancreatic, bowel, lung and ovarian cancer, faster.
