A new project out of Harvard and the University of Nottingham has created a lot of buzz all over the internet in the last couple of days, and rightly so. It seems that Adam Celiz, a therapeutic biomaterials researcher from University of Nottingham, and his fellow researchers, have developed a new kind of filling made from synthetic biomaterial which stimulates the growth of stem cells in the pulp of the tooth. Just like a regular filling, the biomaterial is injected into the tooth and hardened with UV light. This essentially means that damaged teeth would heal themselves. Every year, dentists...

If you travel in the US you’ve likely passed through a whole-body millimeter wave and/or x-ray scanner. Although the government claims these devices are safe, that the health effects of such devices have been thoroughly investigated, the EU & UK have banned such technologies. So, what’s the difference and what’s the potential problem? Millimeter wave scanners use non-ionizing electromagnetic radiation similar to that used by wireless data transmitters, in the Extremely High Frequency (EHF) radio band (which is a lower frequency than visible light). The health risks posed by these machines are still being studied, and the evidence is...
