ERK! Got antibody to work.

Using Sigma's ascites-grown monoclonal antibody against diphospho-ERK, I now see the expected signal in a subset of micromere cells - the ones closest to the organizer cell 3D - in whole untreated ...

Results are in

Snail chow made with 'Monterey' Btk has no effect on reproduction or any other part of the snails' life, either during a ten-day feeding regimen, or for a week thereafter. Here is a table showing e...

Numerous tiny pink blobs

I wasn't expecting to report anything only 48 hours into the trial, but I've seen something maybe never seen before, and I can't keep it to myself. Egg production does seem already to be depressed ...

Starting new trial: Btk vs Bg (M)

Doing things differently in some ways this time. Only two groups per treatment, not four. Groups consist of ten snails each as before, but they get a much bigger volume of artificial pondwater - 15...

Sublethal effects of low-dose Bt: potential for population control

In a four-week trial, snails were fed on alternating days with chow ('snail gel') made with (1, 10, 100, or 1000 ppm) or without Dipel Dust.They were good snails and always ate all their chow.Bt ha...

Correction: the dose was about 0.3 micrograms per snail per day - not 30 micrograms. Darn powers of ten - if I were better at figuring them in my head I might be a millionaire instead of a thousandaire. Well, so the poison is a hundred times more potent than I thought - and might sterilize snails at a dose that doesn't actually hurt insects. Wow. Need to repeat this experiment. Extraordinary claims require extraordinary evidence.

Dipel Dust is a commercial formulation of Bt kurstaki, a strain known to especially target larvae of lepidoptera (moth and butterfly). The label says it contains 0.064% Bt fermentation solids - all the rest is filler. ~~~ How much 'Bt fermentation solids' did each snail eat per day on average? 1.56 gdd/1000 mLsg * 0.064 gBt/100 gdd * 6.25 mLsg/chunk * 1 chunk/2 days * 1/10 snails = 3.1 x 10^-7 gBt/snail day ... So with the '1ppm' treatment, each snail ate, on average, about 30 micrograms Bt per day. ((( gdd = grams of dipel dust mLsg = milliliters of snail gel food gBt = grams of Bt fermentation solids ~~~~ Now if such a dose reduces reproductive output by more than 50%, then just how nasty a reproductive poison are we looking at? ... Estimating the snail's body weight (not counting the shell) at about half a gram, then that 1ppm dose is about 60 mg poison per kg body weight (mg/kg). ... The worst class of poison for humans, according to the US Code of Federal Regulations, is defined as 50% lethal at a dose below 50 mg/kg. ~~~~ How potent is the sterilizing effect on snails compared to the killing effect on insects? Actually not too much different. I am reading about a median lethal concentration in caterpillar food (LC50) of about 22 ppm.

The caterpillars all died - they needed an experienced caretaker. That's OK - they were only there as a positive control, in case the Bt had no effect on snails. It turns out the Bt works on snails!

Cool, I want to see them growing! Also, what about trophoblast organoids? Isn't this the kind of cell that the virus has to get through to infect the embryo/fetus?
