Multiple sclerosis (MS), a disease where the immune system attacks the brain and spinal cord, affects nearly 1 in 700 people in the United States. Patients with multiple sclerosis have a variety of neurolog... Read More
Scientists in the US have discovered a new class of biological antifreeze molecules - the first that do not contain proteins. The antifreeze, extracted from an Alaskan beetle capable of surviving at -60°C, consists of linked mannopyranose and xylopyranose sugars, termed xylomannan, associated wi... Read More

Here's what you can get out of about a liter of LB agar. They have a very low concentration of Tetracycline in them to allow for a more permissive growth pattern. All in a night's work! Read More
My narration in this video might have been a little more accurate, so I'll clarify here:
Essentially we are trying to make a protein in B. megaterium fluoresce with GFP, green fluorescent protein. We are doing so by transforming it with a plasmid that gives resistance to Tetracycline, an ant... Read More
