Since the daffodils are out in full force here in the upper left-hand corner of the U.S., I decided to revisit this post from 2013 and revise it a bit. Hope you enjoy it (again?)…. Doesn’t the Scientific Study of Flower Development Ruin the Aesthetic Beauty of Flowers? Here’s the…
News “Roundup®” This has not been a good month for the herbicide Roundup®. (You can read a brief introduction to Roundup® here.) Both the New York Times and Science magazine featured news articles about this widely-used herbicide (see References below), and the news isn’t good. Briefly, the NY Times article…

And where on Earth did it occur? These are some of the most hotly-debated questions among botanists today, partly because some of the fossil-based…

Moving Genes Around A recent report that a species of aphid can make carotene thanks to a gene it apparently acquired from a fungus got me to thinking about whether genes can flow between different plant species. When an organism incorporates genetic material from another organism without being the offspring…
