I think it’s more like sunlight energy + adhesion energy - cohesion energy, because the capillary action is also helping to lift the water but generally yes the energy is coming from a combination of the chemical forces in the water and the pressure gradient from the sunlight/heat.
Generally, yes, but in the case of trees there is also negative pressure (vacuum) exerted from transpiration when water leaves the top of the tree and “pulls” other water up behind it.
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.
Agreed. We have kept wearing masks in specific places (public transit, crowded events, airplanes) and it really does make a difference. I never get sick from airplane trips any more, which used to be a fairly regular occurrence.
I will say, I was never able to figure out how to stop a properly fitted mask from giving me a terrible headache after 8 hours of use so I’m glad I work from home and don’t need to make the choice of mask vs comfort at work.
I have a white Prius named Shadowfax so if I need to go somewhere fast I can yell “run Shadowfax, show us the meaning of haste!”
Local takeout ftw. I haven’t eaten at a pizza chain in years and don’t miss it at all!
Now the real question in New England is Italian-style vs Greek-style pizza
Another vote for mindustry! That game is a blast.
Highly recommend IGNEA if you like melodic metal. A few faves:

But gosh their stuff is just all awesome.
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.
Jaws doesn’t quite fit the prompt but although it’s a good movie, the book is essentially a sub-par beach read. And there was no USS Indianapolis monologue in the book.
I pay $15 a month for a plan with 5gb data. But even their unlimited plan is $30 a month. So yes, mint is cheaper assuming you are talking about just one phone.
Letting kids (and kids at heart) go wild with their imagination and dress up.
Meeting/seeing neighbors.
Eating candy.
I feel really sad for all the folks on lemmy having a bad/frustrating Halloween. I think it doesn’t have to be that way, but it does definitely take neighborhood-level effort. We’re really lucky to live in a big Halloween neighborhood in a walkable area. We saw all our favorite neighbors and met some new ones, and enjoyed all the creative decorations and costumes we saw while we were out.
But the best part of the night is always getting to see people light up when you recognize their costume. Every time I see a kid dressed as Batman and go “whoa there’s Batman!” or compliment a princess on their beautiful dress, you can just see them stand up straighter or strike a pose and it’s awesome to see everyone dressing up and enjoying themselves. I probably saw a dozen Marios tonight from age 2 to age 20 and every single one of them was over the moon when I complimented their costume.
