Virus for biological pacemaker in heart
Researchers have done this by injecting genetically a modified virus carrying the Tbx18 gene into guinea pigs.
Tbx18 is the gene responsible for the pacemaker cell development during the embryonic stage.
This causes ordinary heart cells to transform in the SAN (sinoatrial node) cells.
When they become infected the heart cells become smaller and thinner, essential having the same characteristics of the pacemaker cells.

Bacteria run battery
Researchers have found a bacteriophage, a common harmless virus to humans that attacks bacteria, can be bio engineered so that it is piezoelectric.
This means that it becomes a generator.
The bacteria-based generator successfully converted the force of a finger tapping into an electrical charge. That means it has the potential to charge a phone or a laptop.

Optimized Bacteria to clean Oil Spills
Oil spills were recently a big issue due to the BP spill a couple years ago.
The fact that certain bacteria can metabolize oil is not a new discovery it was discover in 1989.
But it was not useful knowledge back then, but now that researchers have the complete genome of the bacteria, they can optimize and alter conditions for the bacteria to be effective for cleaning up the oil.
