1. If I can quantize the atom using this hyperbolic spiral and classical physics, could nature do the same?

If we map as a continuous motion an ionising electron (beginning its journey at n=1) in an H atom, a specific hyperbolic spiral appears (see animation). When we solve this spiral formula, we find...

Can I use CCCP instead of H₂O₂ as a positive control for ROS measurement through flow cytometry?

I am giving starvation stress to the soil amoeba (Dictyostelium discoideum) cells in my study groups and using NAC as a negative control. I am using DHE for ROS measurement.
