Finally, Is This Really “The Last Roundup®”? It’s been a pretty horrible year or so for herbicides. Last month there was a lot of bad news regarding the commonly-used herbicide Roundup® (glyphosate). A jury ordered Monsanto to pay $289 million to a cancer patient in a Roundup® lawsuit. (This led…
“Strawberry Fields Forever”. Thanks to this 1967 Beatles song (see below), strawberries may sometimes be associated with psychedelia, especially to people of a certain age (i.e., old farts like me). This comes to mind because psychedelic drugs have been in the news recently thanks to the publication of a popular…
From Flowers That Smell Like Stressed Bees To Corn That Smells Like “Help Me!” October 2016 seemed to feature an unusual number of quirky plant news stories. For example, we previously saw an orchid that smelled like body odor, presumably to attract mosquitos. Now here’s another weird flower smell… “A…
The “Inside” Story? An article in Science magazine (see Ref. 1 below) reports evidence supporting the hypothesis that leaf-dwelling, nitrogen-fixing bacteria may provide host plants with significant amounts of nitrogen. In the past, we briefly explored the microbial phyllosphere, that is, the microbes – including nitrogen-fixing cyanobacteria – that dwell…
Signature Scents of Death & Decay In a previous post, we explored the discovery that plants emit a wide array of volatile organic compounds (VOCs) and that, because of this, sometimes plants stink. But I think few would argue that the prize for the “stinkiest” plants would have to go…
New Meanings For “Medicinal Plants”? Plants have been used by humans for thousands of years as a source of medicines, some effective, many not so much (except perhaps as placebos). The first botanists were likely shaman herbalists who possessed the knowledge of which plants would kill and which plants would…
I’m Melting!! Remember the melting witch in The Wizard of Oz? What if corn stalks, for instance, could be induced to “melt” – that is, to go from tough biomass into a sugary puddle? In biochemical terms, it would be the equivalent to the conversion of cellulosic biomass into a…
“Hot Plants?” In the previous post, the topic was how plants survive the cold. Although some perennial plants can withstand winter temperatures well below zero (F), plants certainly don’t generate body heat like mammals do in order to warm themselves. Or do they? There are a few plants in nature,…
Roundup® Kills All Plants (Mostly) The herbicide that most Americans are likely familiar with is Roundup®. Unlike the auxin-based herbicides I discussed in the previous post, Roundup® is not a selective herbicide. That is, it usually kills all green plants (except if the plant is Roundup Ready® or if the…
