Designer Genes Getting CRISPR and CRISPR

Heads up! A new technology is transforming gene editing. It gets my vote for top science news of last year. It will affect us all more than we can imagine. And the most surprising news may be its inventor. Many things can change the code of DNA. Chemicals, X-rays, ultraviolet, cosmic rays, and mistakes during […]

Let’s Feed Our Genes

New science is using genetic analysis to discover more of who we are. We now know most of our cells are bacteria. Until recently we knew little about what they do. Mostly we get rid of them as best we can. This turns out to be a major oops. In a previous post I reviewed […]

Billion Dollar Bugs

How about a multi-billion-dollar good-news story? Science may have found a way to grow more food. It’s a source of nitrogen: bacteria that live in leaves. It may be worth a mint in new ecosystem services, which is a name for what Earth does for us by being there. Here’s the scene you need to […]

Be Careful What You Wish For

Each shapes its environment (you) by talking to co-conspirators. Cells do this instinctively. Their ancestors survived by doing it for millions […]
