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

AN HIV virus modified to infect monkeys could be a big step forward for HIV research.
The disclosure last month that an experimental vaccine against HIV may not be as effective as first thought highlighted a nagging problem with HIV-vaccine research: that there is no effective way of testing ... Read More
Bacteria possess an ingenious mechanism for preventing oxygen from harming the building blocks of the cell. This is the new finding of a team of biologists that includes Joris Messens of VIB, a life sciences research institute in Flanders, Belgium, connected to the Vrije Universiteit Brussel. Th...

Back in 1885, a German-Austrian pediatrician by the name of Theodor Escherich was investigating an unusually high incidence of infant mortality due to severe diarrhea. Using the newer, more powerful microscopes, he soon isolated a rod shaped bacteria derived from a residue best left unmentioned.... Read More
No matter how much yogurt we eat or kambucha we drink, no matter how much we hear about how bacteria can be beneficial to us, it still can seem creepy that there are up to 1,000 species of bacteria and fungi lounging around on our skin at any given time--1 trillion or so microscopic residents.

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
