This level of labeling accuracy is high enough to allow researchers to build a subsequent system to accurately determine the behavior of a bee from its sequence of motions, Balch explained. For example, one sequence of motions bees commonly perform are waggle dances con...American Society for Microbiology publication provides guidance for shipping biological agents

...To test their theory, they used sophisticated cell labeling techniques to track the decedents of the stem cells during normal hair growth and isolate them in adult mice. They transplanted a slurry of these cells into the skin of a different set of adult mice with no immune systems. (The absence of an immune s...Bay area to get unique x-ray microscopy resource
