Superweeds, not an issue?  You are obviously not a farmer.  They are a big deal.  They won't eat you in the middle of the night, but the expense of dealing with them will.  You might stick to neurology, something you know about.

I was hoping and expecting to see some follow-up on the shrimp SoF question.

The advert for a pantload of steaks is kind of ironic isn't it, being in the same episode as the warning about humans destroying the environment. 
Beef seems to have a massive negative impact on the environment.

Why not talk about how that particular sponsor compensates for their effects (if they do?) or advertise for someone like Memphis Meats instead? 

I'm no vegetarian, for the record, but try to remain cognizant of my beef consumption. 
Hope I'm not violating some protocol by poo pooing a sponsor - not my intent - I just found the contrast striking.

Far be it from me to speak for the man, but it seemed he was responding to specific claims that there's a risk of superweeds being resistant to "everything," like antibiotic-resistant bacteria.  Didn't seem to me like he was suggesting they're a complete non-issue in all cases.

But they're not superweeds. They're just developing immunity to the herbicide that you don't want farmers to be using anyway. The use of glyphosate does not make weeds any more resistant than they were before to all the other ways farmers have of killing them.

Me, too. I was wondering if maybe I'd missed an episode where they talked about it.

Weeds that become resistant to glyphosate are called 'suprerweeds'. Loss of the ability to control them with the cheaspest and safest chemicals is a big deal, especially for producers of certified seed.  Just because we don't generally use herbicides (or soluble fertliser) on our farm doesn't we don't want all farmers to use glyphosate.

I'm not sure what you are advocating. Pests become resistant to pesticides. Glyphosate is in that sense no different than any other pesticide. Before glyphosate (and other herbicides) farmers had to kill weeds by tilling. Once they become resistant, farmers will again have to kill weeds by tilling. Roundup-ready seeds allow farmers to use glyphosate. Once the weeds become resistant, glyphosate will no longer be useful and farmers can go back to using other kinds of seeds. And older methods of weed control.

Ja wohl!

Ypsilon is actually the word for Y in german. As in Ix, Ypsilon, Zett (X Y Z). But, yes, it does have a Y in it.  :evan:

It is rare, found in a lot of borrowed and very technical words, but here are a few more common everyday-use ones: physik (physics), gymnasium (high school), zyklon (cyclone), zylinder (cylinder), typisch (typical), systeme (systems), Bayern (Bavaria), Ägyptische (Egyptian).

In Soviet California, judicial system SLAPPs you!

On a more serious note, I take it that Science-Based Medicine is owned and operated by the Society for Science-Based Medicine (SfSBM), which is a 501(c)(3)?

A lot of the chemical effort in industrial agriculture today is suppressing last year's drop. For instance Iowa farmers rotate corn and soybeans, but when you go with soybeans this year, you have a problem with "volunteer corn," which is seed from last year's corn growing among your beans.

So you get in this viscious chemical cycle of needing to sustain the rotation. In the past, you would hire a kid to "walk the beans," pulling volunteer corn and hoeing out other weeds. But we are now industrial, with one guy in a high-tech tractor.

That one guy in that high-tech tractor will soon be replaced. That, and a weed killing bot will walk the beans without concern for a miserly stipend.

It's already happened. It's been a couple of decades since beet thinners were introduced and became widespread. Sugar beets have poor germination, so farmers have to plant the seeds thick, and then they used to hire migrant workers to walk the rows and thin the seedlings. Now there is a machine that they pull behind the tractor. It senses the seedlings and zaps the unwanted ones with an electrical spark that kills them, leaving the right number of seedlings in the row. People come up to North Dakota and Minnesota from Texas to work in the sugar beets, but there's much less work for them now, because they're no longer needed for thinning, and there are fewer weeds after the herbicides have done their work.

Not a walking robot. Just a machine pulled behind a tractor.
