Cystic fibrosis is a fatal condition that claims patients at an early age, so why does it persist? Soaring seed prices are hitting farmers hard. What explains the exorbitant price increases? The European Union says mutagenic plants aren't 'GMOs.' Why does Europe oppose more precise genetic engineering techniques while accepting crops produced through less controlled methods?

* Cystic fibrosis chronicle: Why has the often-deadly CF gene not passed out of the human genome? And what new treatments are being developed?

Cystic fibrosis (CF) affects some 10 million people, claiming many of their lives at an early age. It's one of the most common genetic disorders in the US and very difficult to treat; so far, no effective therapies have emerged. But that raises an important question: why does the defective gene behind the disease persist in the human genome? Some evidence suggests that the carriers may have enhanced resistance to other conditions, which could extend their lives under the right circumstances. The good news is that scientists are developing a treatment based on phage therapy, deploying viruses that literally eat harmful bacteria. The therapy targets one of the main causes of serious complications in CF, recurrent infection of the lungs. Will this treatment survive clinical trials and begin saving lives?

* Soaring seed prices: What role do patents and regulation play?

$130 million over 13 years. That's what it can cost to develop and commercialize a new crop variety. In order to recoup that investment, patent protection ensures that only the developer can sell the new crop variety for two decades. That makes some economic sense, but it also means that farmers have to pay higher prices for seed. When you factor in the added expense of regulation, seed prices can reach stratospheric levels—sometimes increasing by 700 percent. This can cause downstream effects, including tight margins for growers and higher consumer food prices. Can anything be done to reform the regulatory environment to cut seed prices?
