Well, for vertebrates it is more complex than that. Those lipids that line your cells? The ones that have just the right viscosity at the pressure you live at? How do they behave at depth?
How do lipids that are fluid enough to function within a single-celled organism at depth (>15,000 psi) behave when they are brought up to our measly ~14psi?
Interesting link. The rule for divers is usually to stay below 1.4 atm partial pressure of oxygen (and above 0.1)
And yet, there are only 2 medical conditions I know of where providing oxygen to the patient is not recommended.
1) In long-term bed-bound hospital patients with very weak respiration, providing supplemental oxygen can reduce the blood CO2 concentration (raising blood pH), which can block the respiration reflex, causing the patient to *stop* breathing. Outside of long-term hospital care of the elderly, this is unlikely to be a concern.
and 2), The patient is actively on fire. In this case, extinguish the fire, then administer oxygen.
The Even Larger Array?
From the article, there are no more dishes than before, and they aren't any bigger, they are just more sensetive. The "Just as Large Array"?
So are the raptors looking for UV, or glow caused by UV?
Because most people can see the visible glow when certain materials are illuminated by UV.
Don't forget underwater - it turns out that corals, cnidarians, lobsters, crabs, shrimp etc. flouresce, while most fish don't. Ongoing research suggests that some fish actually alter UV patterns to communicate.
I am going to pretend that all these nerds on
Where are the calculations that go with a calculated risk?
