A GPS for inside your body

Novel wireless system suggests future where doctors could implant sensors to track tumors or even dispense drugs.

Weaponizing oxygen to kill infections and disease

A paper battery powered by bacteria

Researchers made a paper battery by printing thin layers of metals and other materials onto a paper surface. Then, they placed freeze-dried 'exoelectrogens' on the paper.

A valley so low: Electrons congregate in ways that could be useful to 'valleytronics'

A new study has revealed an emergent electronic behavior on the surface of bismuth crystals that could lead to insights on the growing area of technology known as 'valleytronics'.
