In IT Blogwatch, it's time to learn something new.

What exactly is going on? Sophie Bushwick has the background:

It’s easy to dismiss Silly Putty as a kid’s toy. But...when you mix Silly Putty with graphene -- strong, conductive carbon sheets with unusual physical properties -- it becomes an incredibly sensitive strain detector that can track blood pressure, heart rate, and even a spider’s footsteps.

Graphene. Isn't that the super strong wonder material? Daniela Hernandez fills us in:
