"Mosses Make Two Different Plants From the Same Genome..."

"... and a Single Gene Can Make the Difference."
[W]hat if, immediately after sex, meiosis was postponed, and a multicellular diploid organism grew as it does in animals. But then, instead of making haploid eggs and sperm that must fuse to form another diploid organism, the diploid creature made a haploid reproductive cell called a spore that simply grows asexually into a multicellular haploid organism? When mature, this haploid multicellular organism would then make eggs and sperm by mitosis (instead of meiosis, as in our ovaries and testes), and voila! The circle of life is complete.

Genetically engineering trees so they will glow in the dark and replace street lights.

Research by "a small group of hobbyist scientists," funded through Kickstarter.

What a dilemma for environmentalists! All the fossil-fuel burning that could be averted, and yet.... Frankenstein!
Two environmental organizations, Friends of the Earth and the ETC Group, have written to Kickstarter and to the Agriculture Department, which regulates genetically modified crops, in an effort to shut down the glowing plant effort.

The project “will likely result in widespread, random and uncontrolled release of bioengineered seeds and plants produced through the controversial and risky techniques of synthetic biology,” the two groups said in their letter demanding that Kickstarter remove the project from its Web site....

"The pollen piece looks like a yellow painting... but it’s much, much more."

"It’s not a yellow pigment, which is very important for me. It’s the potential beginning of millions of plants. It’s the semen for the plants. And this I was interested in. It has an appearance, maybe, like a painting, but the sun is not a round ball. It’s much, much more. The sky is not a blue painting. For me, these things were somehow very important. I would have stayed as a doctor, if art was only about this color or that color."
