Dilatant Compound 3179 + Graphine = Hypersensitive pressure detector

Dilatant Compound 3179 (previously), better known to kids young and old as Silly Putty, may finally have a proper scientific use (besides the other semi-proper uses). Add graphene to the polymer, you get a very sensitive electro-mechanical sensor that can measure breathing, pulse and even blood pressure when placed on a person's neck or chest, and even detect the footsteps of small spiders (via NPR; abstract, paywalled article on Science Mag: Sensitive electromechanical sensors using viscoelastic graphene-polymer nanocomposites).

"The Quake-Catching Network is a collaborative initiative for developing the world's largest, low-cost strong-motion seismic network by utilizing sensors in and attached to internet-connected computers." The Economist's writeup notes that, since network communications are (sometimes) faster than the speed of sound in the earth's crust, a distributed network's observations of a temblor might reach a warning network before the quake itself reaches a traditional seismometer.

Horny _and_ sensitive!

The narwhal, often termed "The Unicorn of the Sea," has a really odd tusk. It's long, spiraled, and there's only one of 'em per animal. Its purpose has been disputed for ages, but at long last, it seems that the answer has been found. And it's pretty damn cool.
