What you are describing is not osmosis, it is capillary action. Capillary action is caused by the forces between the water molecules and the molecules of the tube overcoming the force of gravity. You can read more here: https://chem.libretexts.org/Bookshelves/Physical_and_Theoretical_Chemistry_Textbook_Maps/Supplemental_Modules_(Physical_and_Theoretical_Chemistry)/Physical_Properties_of_Matter/States_of_Matter/Properties_of_Liquids/Capillary_Action

Briefly, the water molecules are attracted to the molecules of the tube by adhesive force. The liquid molecules are also attracted to each other by cohesive force. The interplay of these forces causes capillary action.

However, it seems that tree sap moves by more than just capillary action. If you scroll down part way in this book they talk about it a bit: https://pressbooks.online.ucf.edu/phy2053bc/chapter/cohesion-and-adhesion-in-liquids-surface-tension-and-capillary-action/

Kids love this shit as long as you keep it at the ELI5 level and stop when they are done and lose interest. My kid will throw around words like "microorganism" and "bioaccumulation" because I actually explain biology concepts when he asks. The other day he had a question about atmospheric composition and he was absorbed for about 5-10 minutes, complete with looking at molecular diagrams, and then he was done and went off to make his Lego people fight each other with flamethrowers.

If you have knowledge, share it with kids and let them see you enjoying science. They absorb more than you might think.

Acetaminophen (Tylenol) if I can't get it under control without meds but I agree with the other posters about trying to figure out the root cause! For me, the main causes of headaches used to be hormones from the pill until I switched to a different form of birth control (IUD). Nowadays my headaches are mostly dry eye or allergy related so I keep eye drops on hand and take allergy meds and I'm down to headaches once every week or two. Staying hydrated and taking fish oil supplements has also helped my dry eyes.

Not OP, but we have a bidet and a basket of cut up t-shirt cloths next to the toilet that are single-use and then go in the wash every week. I wouldn't personally reuse washcloths for wiping out of fear of UTIs, but I'm extra paranoid.

Highly recommend IGNEA if you like melodic metal. A few faves:

But gosh their stuff is just all awesome.

They help significantly to combat the heat island effect in cities and provide shade and cooler microclimates for people to shelter in when it's hot.

Just try going to a shady tree-lined path vs. a paved treeless path on a sunny day and you'll be pretty clear on the meaning of this meme.

So yes we can't stop global warming with trees alone but we can mitigate the local effects of it all while providing habitat for birds and shade for people and lots of other benefits besides.

This article has a pretty good review if you want to take a look at some of the benefits! https://www.mdpi.com/1660-4601/17/12/4371

And here's a more plain-language website about urban trees: https://www.climatecentral.org/climate-matters/the-power-of-urban-trees-2023

Cucumbers need a lot of direct sun and a lot of space, either vertical (trellised) or horizontal (along the ground). Put them in a wide open sunny part of your yard. They're also fairly susceptible to powdery mildew so keep an eye on them if the weather is rainy.

You mentioned you're in Maine, which means you have a relatively short growing season. You might want to start your cucumber seeds inside to get a jump start on the season in the spring. Otherwise just make sure you get them started right away once it's okay to plant outdoors so that you don't run out of room at the end of the season.

Good luck and let us know how it goes! Cucumbers are a very rewarding plant, right up there with tomatoes for me as far as bang for your buck. Homegrown cucumbers have a crunch that totally knocks store bought ones out of the park.

Other vegetables I like growing that grow well in my corner of New England: Basil (grow enough to make several batches of pesto and freeze it) Tomatoes Sugar snap peas Leafy greens, especially collards and Swiss Chard Potatoes in 5-gallon buckets Hot peppers

My mother in law lets her cucumbers grow along the ground and they do great. Not sure if she buys a specific variety that's not for climbing but it's definitely possible to grow cukes without a trellis. Same as you would squash.

That said, a trellis saves a lot of space.

Thank you for reminding me this plant is edible. I've always wanted to try it as a tea and I've got a very healthy patch of it this year!

You would need a pretty big solar array to power a construction site with it. But you're headed in the right direction. Not only is it an option to use renewables to power battery-powered vehicles, but also pretty much any form of electricity generation increases in efficiency and decreases in emissions (per kilowatt generated) as it scales up. Even if you are burning the same fuel at the power plant, the emissions are going to be lower overall than the equivalent number of individual internal combustion engines because the efficiency of the power plant is much higher than an ICE. Vehicle engines are ridiculously inefficient overall and when you use a more efficient fuel like natural gas it is even more drastic of a difference.

It's also much easier to put stack controls on a power plant to capture or reduce emissions than it is to put emissions controls on all construction equipment individually. This has implications for carbon capture, which could happen right at the stack. However, there's a non-climate change benefit here as well which is that the local air quality would be greatly increased around construction sites. Currently most construction equipment does not have much in the way of emissions controls for other things like sulfur and nitrogen oxides or particulate emissions. Power plants have to meet emissions standards for all of these.

I recently got an ebike, and I'm shocked at how much it has improved my ability to get exercise over just having a normal bike.

On days when I'd skip biking to work or the store because it's too hot, I can go on the bike and get a moderate workout. It's got a huge cargo basket so I'll take it on shopping trips instead of the car. My son can ride on the back so sometimes it's the school drop-off vehicle. Being able to go faster with the e-assist means I don't worry about being late as much. I bike SO much more often and even though it's less of a workout than with a regular bike I think on the whole I'm getting more regular exercise so it's a win.

I also have a folding exercise bike at home, and try to hop on it if I have a long conference call where I'm going to be on mute the whole time. It doesn't happen often but it's enough that it adds a little bonus exercise.

I would have had a local barbecue joint cater the wedding instead of getting a fancy caterer. The food was the most stressful part of our wedding and it wasn't even that good for the price and trouble.

Would keep the strawberry shortcake instead of wedding cake though, that was bomb.

Other than the food I wouldn't change a thing. I married the right guy and he's just gotten more awesome with time. And we had a (relatively) low-key wedding to start with so there's not much I have in the way of regrets.

 

Hey all, I'm curious if anyone has experience planting shallots in the fall to overwinter in New England or a similar climate (6a-6b). I'm in the Boston area so we get cold winters but they're not brutal and I have some friends who grow garlic over winter with great success. I've read that shallots are less hardy than garlic but I don't really have any experience with root vegetables over winter so I have personally no clue!

I'm planning to try growing them in a raised bed and could potentially put row cover on them if that changes things.
