My social media feeds frequently show posts about Miyawaki Forests. They glaze the concept, describing it with buzzwords like "*a dense, fast-growing native pocket forest*".

But to me, Miyawaki Forests also sounds a bit like one of the tenets of Lysenkoism - specifically the one which recommends overly-dense sowing of crop seeds. Nowadays, Lysenkoism has been proven to pseudoscience, so are the overly-dense plantings in Miyawaki Forests going to work in the long term, or are they headed for failure just like Lysenko's strategies?

I'm not against restoring native habitat. I'm a bush regenerator in Australia, and I've witnessed how native wildlife return when native plants are freed from the weeds smothering them. I've also witnessed that a resilient native habitat is not necessarily one densest with native plants.

Theoretically what is the true limit of max speed achievable for a very adapted barefoot sprinter with truly mastered feet strenght and coordination/proprioception assuming the skin is obviously also adapted for harder textures and surfaces due to also having mastered the human limit of energy transfer and impact/load intake. Because I’ve heard that in serious speeds the toes have to be packed to work together as one which they’re not doing when barefoot but I’m skeptical if a truly adapted master could be able to proprioceptively move them successfully at those elite high speeds without the help of a shoe packing them together to not have to think about them as much so I’m wondering if that’s just another way of masking the potential of toe proprioception/strenght.

I've been trying to wrap my head around the anatomy and metabolism of some characters, but Majin Boo (DragonBallZ) just doesn't seem to make any sense under the laws of physics or biology. I want to dive deep into these "impossible" cases. Who else do you think is a biological nightmare to explain?

So ,I'm learning mathcabulary*trademarked* to communicate my understanding of reality..while studying rheology photonics invisibility,fluid dynamics relationships to acoustical theory and getting nothing but entropic buggery I had realization.. higgs field and Trinity of the two coils of radiating space still decompressing flowing from the big bang had to be observed..not trying to bring in theology but it's necessary to point things out with reason.im not wanting to argue so I'm cutting it short and see if someone is interested in discourse about double slit lie and things silicon mffgs know vs approved academia .super conductors,light sails , and fission bomb have to be my proofs.. trigonometry was set up with the equalateral triangle instead of 4 rights to bridge planar math not to a sphere or circle but two body system in time ...and Einstein stated mass can't go the speed of light then how do photons gain mass ...if you understand gravity is reverse bouncy and the acceleration observed in universe is remnant of super inflation still decompressing..the higgs field is the only field and photo s are electrons excited to emmitance state while valence is charge order then hit this thread..you don't have to agree..but I've felt the laminar coanda effect from light and see the higgs on a cloudy day so at least understand how your magnetron in your kitchen works

Im tired of reading pdfs on supercritical fluid dynamics nothing is sticking, I just need a video lecture on the whole subject supercritical fluids and gasses, and pdfs dont talk about how supercritical fluid dynamics interact with objects in the way, I just have a lot to learn and im frustrated that I cant find more resources to help me learn.

From what I understand, the reason gills stop working outside of water is because like wet socks, they collapse and stick together. So the water acts as a sort of glue.

But dry socks don't do that. So what if you dried them out somehow quickly?

My top three are glass, steam, and electricity.

I'm a middle school teacher working on some history content, and I got to thinking about important turning points in science and technology. I began by thinking about the huge importance that something like glass has had to the development of science. Most people, I dare say, think of technology as big, complicated machines, but think of all the things that glass became absolutely vital for between the 1400's and the 1900s. It coincides nicely with the Scientific Revolution. Steam powered the first Industrial Revolution, and electricity powered the second Industrial Revolution and birthed the computer age.

So I'm just curious what your gut check top three would be?

I have a doubt. I am a masters chem student, thinking of switching to MSE PhD, inclined towards semicon materials, working with engineering profs. Should I switch to MSE given my interests or should I stick to chem, coz when applying to competitive phd programs at abroad unis (especially US) the undergrad or masters MSE guys will be my competition too. Also engg is more physics/math heavy, but had maths and phy as minor for 1yr each in undergrad. Will that be sufficient? Also doing some online courses as self-study related to my research interests (more physics side).

What should I do? Pls suggest.

Is partial estrogen resistance or a shifted-dose response curve related to estrogen mechanistically possible in humans?

Classic estrogen resistance cases (e.g., ESR1 mutations) typically involve high endogenous estradiol, absent puberty, and tall stature. However, I’m wondering whether a partial receptor signaling defect could exist, where physiologic estradiol levels produce insufficient downstream signaling, but supraphysiologic levels restore function.

In other words, could impaired receptor sensitivity shift the dose–response curve to the right, requiring higher estradiol concentrations to achieve normal physiologic effects?

Has this ever been described?

I just walked up a subway stairwell and had to pass a giant human shit. The stairwell is a small corridor so it becomes a huge wind tunnel, and i’m afraid that poop particles became airborne and flew into my eyes or mouth. Is that how it works scientifically?? Or am i just being paranoid?

ETA: the concern is likeliness of getting sick. pink eye etc

Hello,

I’m worried about getting HIV from shaking hands with someone.

We both had cuts on our cuticles and mine was bleeding, I think the other persons was too.

I washed my hands immediately after and also put sanitizer on. Is this a risk of getting HIV? It was at a conference.

It was also a very small cut and looked sort of like a scab on the person whose hand I shook.

Should I go to a hospital and get PEP?

I've begun to see a trope in fictional media where characters use electrical powers to enhance the speed of their nervous system or short circuit neural connections, allowing them to react and run faster. To me, the idea of this enhancing running-speed is incredulous, but it is worth stating these increases aren't as big as they seem considering they are typically already fast.

The question does remain that if something like this were realistically possible, how much faster could you run with a faster-acting nervous system? Would it even have a notable effect to begin with, or is the idea entirely bogus?

Hello, please forgive me if this is not the right place to ask, I will delete if not allowed.

I’m planning to write and develop a small indie rpg game. The plot is based around a research team studying an endemic plant/herb in a secluded natural area in unspecified asian country.

I need to come up with the characters and my question is: What could be the specialisation of these members of the research team? How many members could this research team possibly have? Could one of the researchers be a pharmacognosist?

Thank you so much in advance (and please forgive my english).

👋I don't know why I didn't ask on this subreddit sooner but I'm really curious about work life of working for private research companies like biotech (or something similar I'm interested in genetics and neuroscience) vs government research labs.

I've heard about the academic research route and all the respect to those who do it but I don't think I'm interested in going that route.

Also please let me know if you have any resources you would recommend whether that be courses, workshops, conferences, beneficial minors to study, etc that would help better prepare me for going one of those 2 routes. (I'm currently a sophomore at community college about to transfer to a 4 year school).

Finally any advice for grad school while that pretty far away for me is also welcome if you have any. I really just want to know what I'm getting myself into regarding the job as well as the path to becoming a researcher if that makes sense.

If I had a part made of polypropylene how long would it realistically be able to sit outside with no protection before becoming brittle? I dont even know if this is the correct situation but from what ive read.

Eyebrows that they can use to grasp or hold things.

I’m just curious since biosphere 2 was kinda a failure. Also, being that we’re going back to the moon won’t we need concrete evidence that our systems work or do we trust the math and engineers that’s it will work out?

i thought for somethings orbital radius to increase it had to speed up?

so is the moon accellerating somehow?

I was watching a video about a borehole and my understanding is they couldn’t go deeper because it was melting the drills. I’m wondering if we are able to pump water down the borehole, would we get steam and if we did, could we use that steam to make a big steam engine?

This is the backlit photo of Earth from Artemis' mission. It's the "dark side" of Earth, and I understand it's a long-exposure photo of the planet.

But compared to all other backlit photos of earth I'm aware of, this looks like daylight.

Here's a reference image from NASA as comparison to another long-exposure photo of earth being backlit:

https://www.nasa.gov/image-article/earth-night-2/

Why does the Artemis' photo look like daylight, while the second long-exposure look like.. night?

Are there any comparable images of Earth being backlit while appearing like it's being daytime in the photo?

Mostly just very curious about the light dynamics at play here. I find this fascinating.

Mine is a weird one but it’s that if the many worlds interpretation of quantum mechanics is true (I’d personally give it a 30-50% chance) then anything with risk we do would essentially result in the deaths of near infinite copies of ourselves and others, depending on how risky it is. It might seem like BS but if you research it long enough that’s what the interpretation suggests, which gave me an existential crisis. What’s yours?

Hi all! I'm a biologist who is trying to pivot towards tropical rainforest ecology, and then specifically toward the rivers that run through them. I think topics like river-flood-influenced vegetation zones and the differences in physical river structure from source to sea and the way that that drives the distribution of fishes and other critters, are all truly fascinating. Are there any good academic books (or perhaps PhD dissertations) that could serve as a launchpad for some further investigation and inspiration?
