"Contributing to more than 11,000 deaths a year, the methicillin-resistant staphylococcus aureus (MRSA) is going on a trip to the International Space Station. With the aim of getting the superbug to mutate faster in the gravity-less environment so that we can see how it will evolve over a shorter period of time than on Earth, and will give us a chance to counter the pathogen." - IFLScience

Today, we did a Gram-Staining practical, where we used Escherichia Coli as our Gram-negative bacteria and Micrococcus luteus as our Gram-positive bacteria. We used Lugol's iodine and crystal violet solutions for Gram stain, and safranin (pink coloured) as counter-stain. Although the results were not as clear as expected, due to the long, messy and complicated process that we had to undergo, increasing the chance of human error throughout the practical.
