Many vertebrates are able to synthesize a sunscreen compound de novo and the pathway involved can be used for heterologous production of the compound in yeast.
Cellular hallmarks of thermal limits are evolutionarily conserved in nematodes, and changes in surface to volume ratio reflect restricted aerobic metabolism at these limits.
