Lego blocks could be the key to detecting nerve gases in the field

Lego blocks destroy the feet of groggy parents around the world, but as a new study from the University of Texas at Austin demonstrates, these mutable children’s toys can also be used for good—in this case, as a simple- and inexpensive-to-construct scientific apparatus.

In the aftermath of a nerve gas attack like the ones that have allegedly occurred in Syria, one of the biggest issues first responders face is figuring out what deadly nerve agent was used. If detection happens fast enough, it can save lives. But the conventional equipment that’s used to ID different nerve gases is expensive and hard to move around. However, as this new paper shows, it should be possible to do this analysis in the field using little more than a smartphone and some Lego blocks.
