A bacterium on its own can’t reach very far. And when stacked on the sea floor in a large colony, it may have access to either oxygen (top of the pile) or food (bottom of the pile).

So for the entire colony to thrive, the bottom and top layers must be choreographed in chemical reactions occurring across great expanses, allowing electrons from food consumption in the basement to react to oxygen from the rooftop.

A new study just published in Nature set to isolate the way bacteria pull of this stunt. The first guess, molecular diffusion, was found to be too slow for as dynamically as these colonies reacted in various testing. Now? It’s believed the bacteria use interconnected nanowires, sharing electrons across expanses 20,000 times their individual size—though to be fair, there’s no direct evidence proving the existence of said wires.

It seems like we’re constantly hearing about promising battery technologies that could ultimately lead to longer battery life, more power, and smaller units, but as of yet, that big breakthrough hasn’t occurred. Maybe nanotechnology, which is the current hot topic in the battery innovations field, will prove to be different.

Right at this moment, a ton of research is being put into carbon nanotubes (CNTs) for a bunch of uses, including electronics and batteries. Researchers are drawn to CNTs because, according to them, carbon nanotubes are near perfect. That has paved the way for a professor and a UC San Diego graduate student to discover a breakthrough that involves introducing purposeful defects into CNT structures. By doing so, the ‘defective’ CNTs actually work better for the development of super capacitors, DailyTech reports.

"While batteries have large storage capacity, they take a long time to charge; while electrostatic capacitors can charge quickly but typically have limited capacity. However, super capacitors electrochemical capacitors incorporate the advantages of both," Professor Prabhakar Bandaru said.

The duo also discovered that other methods, such as bombarding CNTs with argon or hydrogen, could also increase or decrease the charge capacity. In the end, the two researchers believe that their discovery could ultimately lead to electronics that charge faster and last longer than what’s available today.
