It’s Just Another Toxic Tuesday

As the days grow increasingly darker, having just turned back the clock, so too the U.S. EPA is working to turn back the clock. Here are a couple of choice selections from this month’s science-realm news; as usual, two downers followed by at least one positive so if you just “can’t stand it” anymore, skip […]

Winter is Coming: the end of antibiotics?

Ok, so this is nothing new. We’ve been hearing about returning to the “pre-antibiotic” era for years now. So when I first heard the news news out of China, about resistance to polymyxin antibiotics (a resistance found in both food animals treated with the stuff, and patients hospitalized with infections) I wondered why all the fuss over […]

Rounding up Resistance

The other day a friend asked if it was true that the herbicide Roundup (or glyphosate) caused celiac disease. My knee-jerk response was that these days Roundup is blamed for everything from celiac to cancer.  Adding that, as the top selling herbicide in part thanks to genetically modified crops (it was pretty lucrative before GMOs as well), it’s […]

And though I have plenty of posts on other stuff, I have shied away from cancer, even though one of the biggest problems with treating cancer is resistance. Yet it is difficult to […]

Life Changing Chemicals

Reposted from Whole Terrain with permission; and from Island Press Field Notes We are a chemically-addicted society.

Of the nearly 37 million pounds of antibiotics used in the United States each year, some 7 million pounds are ingested […]

Evolution is just warming up

There are many ways we influence evolution in contemporary time, or in our lifetime. While I have been focused on how we influence the process by way of the chemicals we use, life evolves in response to fishing, hunting, driving, and now there is evidence that life is evolving in response to climate change. No […]

Rapid evolution, not all that bad?

In case you missed it, there’s some positive news on the rapid evolution front. We all know that HIV the virus that causes AIDS is a master of evolution. Rapidly evolving in response to both drugs and the human immune response. Yet after battling it out over several decades at the cost of too many human lives, […]
