Scientists have shown how bacteria could be used as a future fuel. The research, published in the journal Bioinformatics, could have significant implications for the environment and the way we produce sustainable fuels in the future.

How Some Bacteria May Steal Iron From Their Human Hosts

While humans obtain iron primarily through the food they eat, bacteria have evolved complex and diverse mechanisms to allow them access to iron. Scientists have discovered that some bacteria are equipped with a gene that enables them to harvest iron from their environment or human host in a unique and energy efficient manner.This discovery could provide researchers with new ways to target such diseases as tuberculosis.

Though bacteria are everywhere -- from the air we breathe and the food we eat to our guts and skin -- the vast majority are innocuous or even beneficial, and only a handful pose any threat to us. What distinguishes a welcome microbial guest from an unwanted intruder?

(DOE/Sandia National Laboratories) Naturally occurring nanotubes may serve as tunnels that protect retroviruses and bacteria as they infect healthy cells. The unexpected shielding may explain why vaccines fare poorly against some invaders. Sandia researchers now have formed similar nanotubes that could be used to duplicate the phenomenon.

Bacteria-resistant Films Created: Microbe Adhesion Depends On Su...
