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/
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.
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.
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.
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

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
Advantages of bras:
Look nice (if you’re into that look, which many people are)
Keep your nipples from chafing
Support/containment for larger boobs
Keep prudish people from being mad at your nipples
Can be worn without a shirt for sports if they cover enough real estate
When breastfeeding, help catch/absorb leaks
Disadvantages of bras:
I would say I wear bras about 30-50% of the time and it’s usually for either support/chafing prevention or looks. The rest of the time I can’t be bothered. I’m also lucky to not have super large breasts. I know women who do may find a good fitted bra to be more comfortable than no bra.
When I was breastfeeding I wore them all the time though because it is super awkward to leak through your shirt in public.
Edited to add bullet points bc I suck at lemmy formatting
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.
Cisgender woman here, I just wanted to add that if my husband were to come out as trans, that would not be a tragedy or something I wished he’d gotten figured out sooner for my sake. In this hypothetical scenario, if it somehow managed to make us incompatible as married partners we’d deal with it but people have gotten divorced for much worse reasons before. The worst part for me would be worrying if he’d been miserable during our marriage, because I love him and would hate for that to be his experience of our time together.
It’s really hard to imagine because AFAIK we’re both cis but personally I’d probably prefer to stay married to my spouse even if he changed his gender identity. I mean he’s still the same person I married and we still love the same things and have a wonderful life and child together. I dunno, maybe it wouldn’t work out in the end but I sure as hell wouldn’t be mad at him for something he couldn’t change.
Anyways, my point is you don’t have to assume that your relationships with cis people will all get blown up if you do happen to be trans. I appreciate the urge to have your ducks all in a row before embarking on significant life events but the truth is that marriage and adulthood is super messy anyways. If you marry someone and have a kid with them the odds are good you will have all sorts of chaotic events to deal with- physical illnesses, mental illnesses, kid stress or illness, weight gain or loss, money trouble, job changes, changes in personality with age, the list goes on and on. The trick to being happily married is rolling with the changes, working hard at your partnership, and being committed to your partner, not having it all perfectly lined up at the start.
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!
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.
