8. Beware the plausible, __especially__ if it works.
[|Diamonds Are a Sperm's Best Friend] Although strong swimmers in their "natural habitat," sperm don't do so well in a dish. But a new study suggests that common polystyrene Petri dishes may be partly to blame; their surfaces soften into a toxic sludge when they get wet, which may harm sperm cells. Diamond-coated quartz Petris don't suffer from the same problem, and it seems that a much higher percentage of swimmers can survive in their neutral environment. This is great news for in vitro fertilization, as the switch to diamond dishes could help fix the common problem of "poor sperm performance" and help boost success rates.
