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.
Yeah. ADHD mom here. Had a good cry tonight about my kid and all his challenges.
I try to keep on the happy face when he’s around but parenting a kid with severe ADHD is really hard sometimes.
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.
Yep I get mad about this as well. Esp since my title isn’t Mrs. it’s Dr.
We always joke they should have addressed it Dr and Mr [my first name last name] but of course the real answer is they should just call people by their actual names and titles and not guess.
Lolol what kind of fantasy world do you live in? Salaried worker here and although my job isn’t 9-5 strictly if I don’t work at least 40 hours a week my pay will be docked. So I get to choose between 8-5 or 9-6 or I can work while I eat and get that cushy 9-5 life. Or if I miss work I can make up those hours by working at night. It’s a real luxury to be able to do that compared to shift work, but the hours are still being counted.
Also stop being so entitled. Most of your life necessities come from industries (groceries, power plants, gas stations, hospitals, etc) where people work on a timecard/shift basis so don’t you come out here and pretend timecard or shift work isn’t a “real” profession.
This 100%. We and many of our peers with a kid are one and done in the current system. But if we could afford college educations for multiple kids, get adequate parental leave, access to early childcare that doesn’t cost an entire paycheck? That would change the decision quite a bit.
But also I’m happy to have fewer kids and let more immigrant and/or refugee families with young kids move here too. Solves the labor shortage and provides a much needed influx of fresh ideas and culture, not to mention getting some folks out of dangerous situations. Somehow all of the people who want to “save the children” are extremely silent on that front when it’s children moving to another country for a better life.
“Michelle Bond and her co-conspirator romantic partner attempted to fund her campaign for the U.S. House of Representatives by illegally using hundreds of thousands of dollars from corporate coffers, among other sources, and then lying to Congress and others to cover it all up,” U.S. Attorney Damian Williams said.
The pair met in June 2021, according to prosecutors, and they have a young child together."
Holy fuck that child is going to have a fucked up childhood. I am so sorry, kid.
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.
Thank you for letting me know this was a thing!! Total game-changer.
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.
I didn’t know I needed Andy Serkis singing the songs in the Hobbit until I heard it, but it turns out I did. Dude has an amazing singing voice.
Highly recommend IGNEA if you like melodic metal. A few faves:

But gosh their stuff is just all awesome.
Aw damn thanks for fixing that! Yes I wrote it as a list and yes I forgot the double space. Still haven’t figured out bullet points in lemmy
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.
