Who would have thought that nanotechnology started at such an early stage in the history of our human race? What's more is that, who knew that artistry and scientific discovery could go hand in hind? As it turns out, in European churches dating back to the medieval era, stained glass windows were already acting as modern-day air purifiers. Holy stained glass windows, Batman!

The Dutch town of Hengelo has an interesting solution for cleaning up the air, as it is currently testing a new type of air-purifying concrete. This special concrete was developed by University of Twente and promises to soak up nitrogen oxide particles emitted by car exhausts. Learn more after the jump!

When we're hungry, food tends to look better to us than when we're not hungry. Blame it on a stomach "hunger hormone" by the name of ghrelin. A Montreal Neurological Institute study has been scrutinizing this in order to understand how to treat obesity. More food for thought follows in the full article, right after the jump.

How would you like to go around smelling things you normally don't get to smell everyday? If the prospect of doing so sounds interesting to you, here's good news: the University of Sunderland has opened the world's first Impossible Smells Exhibition to the public.

Smells like something interesting to us. For more olfactory news, turn to the full article after the jump.

It would seem that the old maxim "Everything in moderation" still rings true today - too much of a good thing can actually be a bad thing. This may be especially true as far as technology is concerned. The reason: too many silver nanoparticles in today's consumer products may be killing off beneficial bacteria. More bacteriocidal news follows after the jump.

Remember all those sci-fi movies where astronauts hibernate in cryogenic stasis during long space flights? Researchers are now looking into a way to make space hibernation a possibility - without the cryogenics though. They plan to make them breathe in swamp gas instead. Wait... Swamp gas? You'll have to read the full article to find out why.

Ever wondered about atoms? Well, you're not alone. IBM scientists have taken their thoughts on atoms to whole new level. In fact, they were able to measure the force needed to push a single atom through the use of a tuning fork. Find out more in the full article.

As consoles get more powerful, they break the boundaries of what they were originally designed for. While they were only limited to games before, they are now lending their power for use in the sciences, from medicine to computing the physics of two black holes colliding. Read more on the role of consoles in the fields of science by going to the full article.

A small study is trying to prove that normal products such as cosmetics and lotions are carrying dangerous chemicals that may prove to be the cause of reproductive problems to humans. But U.S. FDA has yet to be convinced that these chemicals are indeed problematic.

The study was spearheaded by pediatrician from the University of Washington and is being backed up by several concerned non-government organizations. More on this after the jump!

Animal lovers, rejoice! Professor Jonathan Dordik has been able to find an alternative to animal testing. A small, rectangular glass chip was designed to mimic human reactions to potentially toxic chemical substance. It seems that our furry little friends won't have to be locked up in cages and endure experiments any longer. Details of his new-found alternative in the full article.
