A while back I blogged about the Science of beauty products and I asked about the biology of grey hairs. And my fellow Indy Science Bloggers The Beauty Brains answered:

Why Do Gray Hairs Look And Feel Different?:

They explain about the two different types of melanin - eumelanin and pheomelanin - and how they are responsible for hair color. Apparently the the melanin producing cells - melanocytes - stop making melanin as we get older. Apparently no one knows how to make it stop either! And they just seem to feel more kinky and unruly - but are actually the same but just stand out more because they are a different color.

Another fellow Indy Science Bloggers - robot guy - was just interviewed by Kilimanjaro magazine! In the interview he talks about astronomy and rocketry and how he was influenced by science fiction. He also talks about how special of a place is the Earth is and how we need to “be stewards of our planet, for there is really no other planet close by suited to our needs”.
