Bacteria have had some pretty great PR, recently. Thanks to a lot of new research about their importance to our bodies, they aren't really seen as soulless microscopic murderers any more. They're colourful, misunderstood beings living together outside the spotlight, freeloading in our guts in exchange for favours. In other words, they're artists.

The bacterial world is rife with unusual talents, among them a knack for producing electricity. In the wild, "electrogenic" bacteria generate current as part of their metabolism, and now researchers at the University of California, Santa Barbara (UCSB), have found a way to give that ability to non-electrogenic bacteria.

This researchers say this discovery could be used in sustainable electricity generation and wastewater treatment.

Researchers at Ghent University have hit on a method of harvesting energy from raw sewage that treats the wastewater without using external electricity. It's all thanks to starving bacteria. Although this method is still in its lab testing stage, industry leaders are already interested in utilising it.

British red squirrels are being afflicted by a medieval strain of leprosy that was thought to have disappeared from Europe over 700 years ago, according to a new DNA analysis. Researchers say the chances of the dreaded disease spreading to humans is low, but the discovery suggests this strain of leprosy has been lingering for quite some time.

Using the CRISPR gene-editing tool, scientists from Harvard University have developed a technique that permanently records data into living cells. Incredibly, the information imprinted onto these microorganisms can be passed down to the next generation.
