听力简介:
As a bitter winter storm rages on the east coast, it’s hard to knock being warm-blooded. But what about the metabolic cost of maintaining a high body temperature? Well, a new study finds that we and many other mammals keep up such a ____1____ temp because it’s a Goldilocks situation—98.6 is just right.
Albert Einstein College of Medicine researchers previously showed that every one degree Celsius rise in body temperature ____2____ about 6 percent more fungal species. So tens of thousands of fungi can infect reptiles and amphibians, but we can only be invaded by a few hundred fungi.
In the new work, the researchers created a mathematical model that ____3____ the fungal protection benefits versus the metabolic cost of high body temperature. And the optimal temperature was 98.1, ____4____. The research was published in the open-access journal mBio.
Too low a temperature and we’re ____5____ fungal infections. Too high a temperature and we’d spend all our time taking in fuel to burn. So 98.6, like that middle bowl of porridge, is just right.
