DailyDirt: Bringing Back The Undead
from the urls-we-dig-up dept
Nature has a few examples of animals coming back to life after appearing to be dead — and not just pretending to be dead, but actually surviving a state of very low metabolism. There are even a few bizarre news reports about people coming back to life. (Ahem, and we’re not referring to a certain someone who is well-known for Easter.) Here are just a few examples of seemingly-extreme resuscitation.
- North American wood frogs can freeze solid and appear dead, until they thaw in the spring and get down to business. The trick is to thaw in the right way. If a frog’s brain thawed before its heart did, the frog would have some problems. [url]
- Hibernating black bears stay dormant for 5-7 months without eating, drinking or doing much of anything. However, a hibernating bear’s body temperature doesn’t drop much — about 10 °F — even though the bear’s metabolism is at about 25% of its normal rate. [url]
- There are a few companies working on cryonics — freezing people who believe they can be revived when medical technology is much more advanced. Maybe these people are hoping to meet Erin Gray someday…. [url]
