"I am going to try and experiment within an experiment today. I cloned a couple genes from yeast and have been spending months now trying to get them into several vectors for my combinatorial overexpression project. However, as it goes with wet messy biology, this seemingly simple process has been fighting me tooth and nail. I have retrieved one good clone out of 56 minipreps (plasmid construct isolation) and tried several ligations. So I have tripled down this week. In the picture here, I have 32 tubes, each with 5 individual E. coli colonies. That is a grand total of 160 isolates. 1.5 mL of cells have been transferred from overnight cultures and I am about to spin, lyse, and retrieve."

A new eco-friendly coating is made by binding a water-loving molecule to a Teflon-like molecule that repels oil. This pairing makes for a surface that prevents oil from sticking to it, while also allowing it to be wet by water.

ScienceDaily (June 9, 2011) - Air and water meet over most of Earth's surface, but exactly where one ends and the other begins turns out to be a surprisingly subtle question.
