This is SCIENCE FRIDAY. I'm Ira Flatow. Yesterday, the Supreme Court ruled that human genes cannot be patented. The case involves a dispute over patents held on the BRCA1 and the BRCA2 genes, the so-called breast cancer genes; and tests a company, Myriad Genetics, used to look for mutations to those genes.
Anyone who has taken some time on Earth Day to contemplate the planet has my next guest to thank. Danis Hayes was the first national coordinator for Earth Day back in 1970, and if I might insert a personal note, Earth Day back in 1970 was also the anniversary of my first science story I ever did. So this is very interesting, and I'm very happy to have as my guest today Denis Hayes, who is, and as I say, he's head of the Solar Energy Research Institute under President Jimmy Carter.
Think for a minute about the victims of climate change. You might envision the polar bear, right? You see a lot of that in the news, atop a block of melting ice or - where there's no ice to grab onto, or the great ice sheet covering Greenland drip, drip, dripping away, or the tiny island of Tuvalu whose people and beaches might soon be swallowed by rising seas.

As the climate changes, coastal cities like Seattle are challenged by rising sea levels.
This is SCIENCE FRIDAY. I'm Ira Flatow. Your brain has nearly 100 billion neurons, and one of my next guests compares that complexity to the Amazon rainforest. In fact, he says there about as many trees in the Amazon as there are neurons in your brain. Think about what the Amazon looks like for a second.
