He and colleagues have determined what gives cholera bacteria their curved
shape and whether it matters (a polymer protein, and it does matter; the curve makes it
easier for cholera to cause disease), how different wavelengths of light affect
movement of photosynthetic bacteria (red and green wavelengths encourage
movement; blue light stops the microbes in their tracks), how bacteria coordinate cell division machinery and how photosynthetic bacteria's growth changes in light and dark.
They do — I mean I see a lot of men who are stressed out but because their hormones aren't fluctuating as much and because fertility is a little bit
easier for a man, because the main goal of fertility is just having good sperm that — that have good
shape and a good amount and good
movement.
