Populations of frogs, salamanders and other amphibians are declining at an average rate of 3.7 percent each year, according to a U.S. Geological Survey study released this week. Researchers say the study is the first to calculate how quickly amphibians are disappearing in the United States.

"If the rate observed is representative and remains unchanged, these species would disappear from half of the habitats they currently occupy in about 20 years," according to the USGS.

This is SCIENCE FRIDAY. I'm Flora Lichtman, filling in for Ira Flatow today. If you could count up all the bacteria in your house, how many different species do you think you'd find - 50, a couple hundred? How about thousands, with an S at the end? My next guest had volunteers swab surfaces in their home - pillowcase, the TV screen, the toilet seat - to see what might be living there. And in each of the 40 households, the same spots were swabbed.

FLORA LICHTMAN, HOST:
