More Evidence Shows Nanoparticles In Sunscreen Do No Harm

More research shows that nanoparticles in cosmetics, including sunscreen, do not penetrate the skin's surface. This study, announced today, again contradicts the unscientific claim long espoused by anti-nanotech activists --- and repeated often by an unquestioning media -- that nanoparticles in sunscreen penetrate the top layers of skin and could cause harm. As I wrote in my Sept. 14 NanoBot post --- "Nanotech In Sunscreen: What's The Harm?"  --- this assertion has been repeated so...

NanoPants 2.0

After a decade, we finally have what looks like the successor to stain resistant "NanoPants." The boys and girls in the nanotech lab have come up with a nanoparticle additive in detergent that actually causes your clothes to create a kind of bubble of clean air around you as you walk. Researchers at the University of Sheffield and the London College of Fashion (yes, you read that correctly, fashion and science going hand-in-hand), have come...

Doctor Who: For The Love Of Nanobots

For all the "Doctor Who" fans out there (and my 8-year-old son and I watch it religiously), you might have noticed that nanobots played an important role in the Season 7 premiere "Asylum of the Daleks," which aired Sept. 1. In this episode, the little buggers convert anything --- living or dead --- to evil Daleks by removing all the love until only hate remains, which in the Whovian world is the very definition of...

Nanotech In Sunscreen: What’s The Harm?

Summer is over, but I still have sunscreen on my mind. This summer I've been enjoying more of my Lake Michigan coastline and taking my children for frequent dips. Like any parent, I make sure they're coated nose to toes with sunscreen. But if I were to listen to the anti-nanotech alarmists, I'd have to check to see if there were any nanosized ingredients in the product. For more than a decade now, anti-technology organizations...

Welcome To NanoBot

So, first a nanosecond about me: I've been writing about nanotechnology for more than a decade now, attempting to make this stuff understandable to a general audience. I am not a scientist. I am a journalist. So, in my obsession and fascination with nanotech, I try to make myself understand it by talking to a lot of really smart people and then translating what they tell me into words that I can understand and,...
