Ultrasound during pregnancy I sure hope so - I wouldn't go as far as distrusting an actual doctor who claimed this, since it's a Physics detail that shouldn't taint the diagnosis, but still I'd be very careful with someone who claims false facts instead of simply admitting to not knowing for sure... |

Ultrasound during pregnancy Radiation?! Ultrasound is sound is a pressure wave, while radiation means actual particles (including, but not limited to, light consisting of photons. I know you didn't write that yourself, but still this requires emphasis - ultrasound is not radiation |

Why do plants have green leaves and not red? @David only if the absorbed energy weren't used efficiently, which would, as you suggest, be a reason for leaves to be not black. You could also have green but inefficient and therefore hot leaves, but evolution would have gotten rid of these already |

Why do plants have green leaves and not red? good point. Maybe in most cases absorbing green was just the first thing that happened (by evolution) and it was sufficient, but I'm just speculating... |

Why do plants have green leaves and not red? nice links, though I doubt black plants are likely to happen anywhere since that would most likely need too many different pigments |
