If you're driving down the road someday and you come across a camper with a 50-foot periscope sticking up into the sky, you just might have crossed paths with Ira Leifer. His quirky vehicle is on a serious mission. It's sniffing the air for methane, a gas that contributes to global warming.
Leifer is an atmospheric scientist at the University of California, Santa Barbara. But you'll more often find him off campus, in a garage, next to a string of auto body shops near the airport.
From NPR News, this is ALL THINGS CONSIDERED. I'm Audie Cornish.
MELISSA BLOCK, HOST:
And I'm Melissa Block. Yesterday, President Obama sent out a tweet drawing attention to a study about climate change. The study found that scientists who say climate change is largely caused by human activities vastly outnumber the skeptics. NPR's Richard Harris has more on the study that caught the White House's attention.
Generations of physicists have claimed that time is an illusion. But not all agree. In his book Time Reborn: From the Crisis in Physics to the Future of the Universe, theoretical physicist Lee Smolin argues that time exists--and he says time is key to understanding the evolution of the universe.
This is SCIENCE FRIDAY, I'm Ira Flatow. This week, scientists at the Oregon Health and Science University, OHSU, announced a breakthrough in cloning of a human embryo. They took adult cells, put the cells into specially prepared human eggs and created genetically identical embryos. It's something lots of stem cell researchers have been trying to do for years without success.
What's on your plate? What do you like to eat? What are you eating for lunch, dinner at this point? As with many things, the answer to that might have a lot to do with what you're accustomed to do and, you know, what part of the world you live in. In some parts of the world, insects can be a delicious part of the diet. Well here not so much.
In Brilliant Blunders: From Darwin to Einstein, astrophysicist Mario Livio explores the colossal errors committed by scientific greats, from chemist Linus Pauling's botched model of DNA, to Charles Darwin's failure to understand genetics--the very mechanism of natural selection.

Ah, if only all summers could be like June, July and August 1740 â when three young guys (and a 6-year-old and a 3-year-old) did a science experiment that startled the world. In those days, you could do biology without a fancy diploma. More people could play.
