Researchers developed a 'Digger Finger' robot that digs through granular material, like sand and gravel, and senses the shapes of buried objects. The technology could aid in disarming buried bombs or inspecting underground cables.

Inspired by insects that suck nutrients directly from plant veins, physicists have studied whether valuable chemical substances can be harvested directly from the cells of plants. Using a harvester measuring only a few microns, they have now achieved a technological breakthrough.

New approaches to battle cancer have already unearthed a treasure trove of useful data -- and they're now being made available for free.
