Scientists have discovered a soil microbe with a gene that kills the corn rootworm, an insect that farmers spend $1 billion each year trying to control.
NPR's Robert Siegel interviews Manu Prakash, a physical biologist and inventor at Stanford University, about being awarded a MacArthur fellowship this year. He talks about his work using bioengineering, not just for basic research, but to invent ultra low cost scientific tools, such as microscopes kids can use anywhere in the world.
A scientist in Sweden has started experiments on healthy human embryos in which DNA is altered. The aim is to determine the causes of infertility. It's the first known use of so-called "gene-editing" tools on healthy human embryos, and critics say it could potentially lead society down a very dangerous path.
A Swedish biologist wants to change the genes of healthy human embryos to find ways to treat infertility and perhaps other diseases. The experiments intensify ethical questions genetic engineering.
When Frances Moore Lappe wrote the best-selling Diet For A Small Planet back in 1971, she helped start a conversation about the social and environmental impacts of the foods we choose.

Engineering professor Rebecca Richards-Kortum wins a MacArthur Fellowship for inspiring her students to invent medical devices for the developing world.
The annual MacArthur Fellowships, also known as the MacArthur genius grants have been unveiled. One of the 23 winners is a ground breaking global health engineer.
Research collaborations often involve scientists from all over the world. A new study looks at plane ticket prices, and how they relate to the direction of science.
All that holiday grubbing does indeed pack on the pounds. How much? Researchers tracked the weights of 3,000 people in Germany, Japan and the U.S. and found a weight spike after every major holiday.
Scientists are finally beginning to understand proprioception, a sense that tells us where our body is in space. Much of what they've learned comes from two girls with a rare genetic disorder.
Archaeologists have found the glassy remains of burnt cheese in an ancient pot. It seems trial and error is a timeless method to the madness of creating good food.
Blobs in space emitting eerie, unexplained light have been puzzling astronomers for more than 15 years. Now, they think they are on to the cause of the mysterious glow.
