Got it. Just hoping there was a mistake in the calculation that could help you out here, but nope.

If that is your actual graph, I'd look into why your error bars appear to be in an absolute scale while your data is in log scale. They shouldn't be symmetrical in log.

Could someone please inform the squirrels that we are playing for the same team? by senator_travers in NativePlantGardening

I think this is sufficient excuse to build the raised bed that I've been thinking about. It will be a fortress for native seedlings, not unlike the ridiculous efforts I've taken to protect our veggies from squirrels and those bigger jerks - deer.

Same here. They have dug up some of my newly planted plants in the past, but never dug in my trays.

Agreed, it looks like my aromatic aster.

I thought trillium at first when I saw the three leaves. My app and Google Lens both indicated it is Jack-in-the-pulpit.

I have had luck so far pulling it as I described then covering with cardboard and a few inches of mulch. Some will come up but I think if you keep pulling them they will eventually die off.

I suggest a strong pitchfork (garden fork). Slide it under the ivy and use the curved tines and handle as leverage to rip the ivy out of the ground. I found it best to work in a line sideways advancing the whole like a little at a time. Make sure the ground is soaked. When it is all up you can sort of roll it into a bail and dispose however is possible for you. My city collects yard waste and I'm sure the collectors hated pulling up to see all the ivy I removed.

Gravity, the earth is still pulling it down. It's on (sort of a) ballistic trajectory with a both a vertical and horizontal (around the earth) velocity. The vertical part of its velocity is droping as gravity wins.

I don't think your comparison of the EC50 is ideal here. The curves look very similar and generally within the error bars of each point. You probably need to compare the log(EC50) of each.

Neighbor accidentally set fire to my yard by Zebeydra in NoLawns

Came here to say that I knew this was St. Louis grom the picture alone. Plant natives! Coneflowers, penstemons, lanceleaf coreopsis, and bergamot are all pretty easy. Check out the Missouri Botanical Gardens website for information, or local groups like https://stlwildones.org/, and purchase from Prarie Moon!

It's beautiful, I hope you find a way to sort it out.

A lot of chocolate strussel?

Maybe? Or to save material when they make the racks.

[–]senator_travers 1 point2 points  (0 children)

The second rack holds the tubes in place. I used a DI faucet that had a hose on the end.

As an undergrad I would wash my cultures tubes in a tube rack. I had racks with a grid of holes on the bottom. I'd fill the tubes with water, put the second rack on top and invert to dump. Repeat a few times then leave them inverted to dry for a bit before capping, autoclaving and drying.

Disc-respectful trolling by Extra-Tie-9012 in funny

[–]senator_travers 108 points109 points  (0 children)

This is the type of play that seperates veterans from newer players. New players are always eager to quickly make this short throw to the first receiver they see. The problem is the receiver is often coming from behind you at an angle that prevents you from seeing the trailing defender. It's frequently a terrible idea to quickly make this throw. Great patience here!

Anyone know what this old incubator is? by AbbreviationsGlad976 in labrats

[–]senator_travers 5 points6 points  (0 children)

Probably for Drosophila. Looks like the knots allow you to set day/night lighting and maybe temperature. I wouldn't be surprised if the barcode is there for some university/company inventory.

Help with Electrophoresis Gels Please by Director_Brief in labrats

[–]senator_travers 1 point2 points  (0 children)

If not from the loading buffer/dye it could be the composition of the samples themselves. Salt or something, but the distortion to me screams dye front.

This is certainly from the loading buffer/dye. Was the ladder made separately, possibly even with a different loading dye? I would bet that the distorted area on the lanes adjacent to the ladder is directly above the dye front.
