The Florida Scrub-jay study reveals that genetic diversity is vital to the species' survival, relying on immigrants from smaller satellite populations for genetic material in mating. The loss of these small populations has led to increased inbreeding and a decline in offspring survival rates.
A study published in JAMA Dermatology found that adults who frequently tanned indoors were more likely to practice poor outdoor sun protection and have multiple sunburns. The results highlight the importance of emphasizing avoidance of indoor tanning and reiterating the need for sun protection and skin cancer screening.
