Watch This Scientist Climb a Wall in Gecko-Inspired Spider-Man Gloves

Gloves that let a person crawl up flat, sheer surfaces like Spider-Man does now exist. Skeptical? Watch Elliot Hawkes, a mechanical engineer at Stanford who led the team that pioneered this breakthrough, test them out.

“To work, the surface you’re climbing needs to be relatively smooth; like glass, varnished wood, polished stone, or metal,” Hawkes says, “but you can attach and detach with very little effort, and to make [the gloves] stick all you have to do is hang your weight.”

Over the past decade, scientists around the world have been trying to mimic the incredible stickiness of the gecko foot. But until now, engineering these materials to work at a human scale was a seemingly insurmountable challenge. It’s not that the materials weren’t sticky enough—it’s that no one was able to figure out how to delicately balance the strain of a climbing human hand across a big patch of adhesive. In a study published this week in the Journal of the Royal Society Interface, however, Hawkes and his colleagues describe how they engineered a solution.

Says Kellar Autumn, a biomechanical engineer at Lewis & Clark College who studies gecko adhesion was not involved in this project: “This is a really big deal. I’ve been dreaming about this for about 15 years, since we first discovered the mechanism that makes geckos stick to walls. And this is proof that we finally understood it well enough to make a person climb a building.”

Starvation Symptoms – The Effects Of Starvation On Behavior: Implications for Eating Disorders

{{Title link: https://web.archive.org/web/20050828195845/http://river-centre.org/StarvSympt.html }}

I thought I would go ahead and share this separately,  because it’s really interesting, based on the Minnesota Starvation Experiment.

Finding this stuff out has helped me understand and deal with some ongoing ED triggers. Just not getting enough to eat (or probably a good enough variety of nutrients)  for a while will predictably trigger the kinds of thoughts and behaviors associated with eating disorders. No convoluted psychological explanations required; just starving your brain will do this.

Recognizing the pattern has helped me keep things at the disturbing thoughts level, and take that as an indication that I need to get more to eat. Rather than get triggered into actual disordered eating behavior. :-| (In my case, I stay hungry a lot from diabetes, with higher energy requirements there—and then also have trouble with remembering to eat enough and just standing up to cook, for other disability-related reasons.)

I first ran across this in the context of crash and yo-yo dieting, but it would apply equally well if you are having trouble consistently eating enough or enough variety for disability-related reasons. That can really foul you up in a lot of ways. And I would also not be surprised to see higher rates of clinical eating disorders among people who do have these disability problems with staying adequately fed, just from the complicated physiological responses there.

Reblogging again because I was reminded of it, and this is important stuff.

Diversity References For Writers

{{Title link: https://diversitycrosscheck.tumblr.com/ }}

diversitycrosscheck:

This began as a response to the #WeNeedDiverseBooks campaign, where a commonly asked question was “Is it okay to write so-and-so characters if I’m not so-and-so?”

The answer is yes. BUT you have to be careful and respectful when doing so. A cool way to find out more about those cultures and identities would be to talk to people who are themselves a part of it. This is where this tumblr comes into the picture as part of the #DiversifyYourWriting initiative.

Basic premise: People willing to discuss aspects of their lives as marginalized people submit “profiles”. This blog utilizes a tagging system that enables writers to easily find suitable people to talk to about the very cultures they are trying to write about.

TO SUBMIT: Head on over to our submit page and follow the guidelines! Become a diversity reference!

This project will add on to our tag directory for identities as submissions come in. It’s constantly expanding! If you have any suggestions or ideas, send them our way!

Slepa Ulica: your shoestring is longer than my shoestring

slepaulica:

slepaulica:

i hate those websites that purport to teach you how to feed yourself on a shoestring budget and they’re all “meals for $10!” and they have people eating lots of stuff from entire categories of food that are closed off to me for economic reasons. if i want to eat a meal for $10, i’ll wait till…

Those websites are definitely for people who are middle class or higher and think they’re poor. $10 isn’t even close to shoestring level here unless you’re talking about a meal that’s supposed to feed a family of four or five people, and really not even then. My average meal costs about $2-3, and that’s taking into consideration that I eat a lot of convenience foods because I don’t really have the executive function to cook most of the time. Something for $10 that wasn’t from a restaurant would be a splurge, and a fairly major one at that. And I’m not desperately poor, either – maybe not even poor at all, depending on how you define it.

Yeah. Out of curiosity (because I am very bad at estimating, really), I did some back-of-the-envelope calculations on the cost of the food I’m putting up for the winter this year, and it comes to about $170 per month or $5.70 per day. And that’s for a menu that includes kielbasa, hot dogs, cheese, milk, ice cream, potato chips, and even a couple expensive heat-and-eat things that I particularly like. (The relative lack of veggies is mostly because they’re expensive here, though, more than because the point of the exercise is to avoid having to go to the store. A $0.50 meal here wouldn’t be veggies, it’d be plain rice or pasta or instant mashed potatoes.)

Dunno what you’re reading, but it sounds ridiculous because it actually is.

cool and thank you. i get popsicles sometimes, they’re about 50 cents, and i tell myself i can spend my daily food money however i want to, so when i have a little extra, i’ll get a popsicle. or i’ll make a half litre of pudding sometimes (~20 cents for pudding powder, 70 cents for a half litre of milk) because it’s really filling and yummy and warms me up in the winter. (i eat it hot). i also make potato chips. my friend gave me one of those slicer things that slices the vegetables really thin, so i slice the potato and lay it out so it doesn’t overlap and i sprinkle it with salt and spices and put it in the oven for 5-10 minutes and then i have potato chips for 2 cents instead of potato chips for $1.

it seems (from the internet) like in america there are a lot of cheap convenience foods, which is why the poor there rely on them as staples. here, healthy foods tend to be cheap and convenience foods are seen as luxuries and can cost as much as an average priced restaurant meal.

and it seems like neither way is the good way. for disability related reasons i would love to have something i could just put in the microwave  or take it out of its package and put it in the oven for 10 minutes (frozen pizza). but due to the price (and also due to figuring out that gluten was why my stomach hurt everytime i ate, which means there aren’t any frozen pizzas i could even theoretically eat) i have to make most things from scratch. and if i have a migraine and can’t really cook that day, there’s not much i can do about it. or if my brain isn’t working well and it’s too hard to hold onto all the steps involved in boiling water without sticking my hand in it…well that sucks. so it would be really nice to have access to cheap, tv dinner type things that don’t cost $5 each.

but poor people in america, they should be able to have fresh vegetables and fruit and milk. they shouldn’t have to buy a big tub of cheap ice cream because it’s the cheapest way to get their daily calorie needs satisfied. neither way is good.

i went and looked in my browser history.

here’s an example of “cheap food for $10/meal”:

http://www.ivillage.ca/food/recipes/cheap-eats-10-delicious-dinners-under-10

this one was the England one I mentioned that seemed relevant to actual poor people: http://agirlcalledjack.com/

http://busycooks.about.com/od/inexpensiverecipes/Inexpensive_Recipes_Meals_under_10_Cheap_and_Easy_Cooking.htm

http://www.seriouseats.com/2013/08/cheap-meals-recipes-for-under-ten-dollars.html

but the title of my post was inspired by http://glutenfreeonashoestring.com/ which doesn’t say “cheap meals for $10”, she doesn’t tally up the prices for each entry, but i guess it’s supposed to be cheaper than something. what i’m not sure. i follow the blog because maybe someday some of it will be useful for me, but most of it is way out of my financial league. for me, gluten free on a shoestring is corn flour ($1/kg) and otherwise just eating naturally gluten free stuff like potatoes and rice. i really do like that blog, with the pretty pictures of all the nice foods, but almost every post on there makes me jealous!

$10 for four servings (which those meals are) isn’t terribly expensive for dinner if (and only if) you’re including meat, but it’s far from shoestring. On the other hand, it’s only about as hard to wrap my brain around the idea of $2.50/meal being “shoestring” as it is the idea of ground beef costing $15/kilo. (I went and checked and the ground beef we just bought was $8.15/kilo.)

(We’re still clinging to middle class thus far, so I don’t have the prices of every food I eat regularly memorised, but from what I know the six or seven non-dinner foods* I eat a day are usually in the range of ~40 – 80c each. (Or, for some context, ~2.3 – 4.7 minutes of minimum wage work.))

*I’m much better with many smaller meals than few larger ones. They’re more like snacks.

I found a really really great sexuality test. Post your results. For shits and giggles.

ceilingtheo:

:(((( I reached the question where you had to choose between relationships that are “Intellectual. I’m much more interested in the mind.” or “Affectionate. I’m SUCH a cuddleslut!” and then I just stared blankly at the screen for a couple of minutes, BECAUSE I JUST WANT TO HAVE ABSTRACT DEBATES WHILE SNUGGLING. I like sex, but I would gladly give it up forever if I could have all of the intellectual discussion and cuddles.

(Results, for the record: You scored 76 Heterosexuality, 36 Homosexuality, and 29 Asexuality!)

bohemu:

You scored 51 Heterosexuality, 28 Homosexuality, and 75 Asexuality!

lulz, IF THERE WAS ANY DOUBT

youwereamazingtoday:

You scored 22 Heterosexuality, 83 Homosexuality, and 27 Asexuality!

FINALLY, CONFIRMATION!

citri:

You scored 80 Heterosexuality, 23 Homosexuality, and 0 Asexuality!

lol oop

7266:

You scored 69 Heterosexuality, 13 Homosexuality, and 61 Asexuality!

rofllll i blame it on the disgust that i had at the questions about cuddling

time to become an insufferable tumbly ace

airandangels:

I know, the words ‘cuddle’ and ‘snuggle’ just gross me out. Even if I do actually want to, like, lie around with arms round each other all cosy and quiet and affectionate, I’m not fucking calling that ‘cuddling’ or ‘snuggling.’

Edited to add my result:

You scored 76 Heterosexuality, 36 Homosexuality, and 35 Asexuality!

You are either straight or bisexual (with an interest in the opposite gender) with a moderate to high sex drive.The higher your score in heterosexuality, the more you are attracted to the opposite gender.

A higher asexuality score means that you place a bigger emphasis on the emotional aspects of a relationship and less on the physical.

justice-turtle:

13 Heterosexuality, 60 Homosexuality, and 71 Asexuality.

A bit skewed by various factors, I think, but better than a lot of online sexuality quizzes…

18 Heterosexuality, 21 Homosexuality, and 73 Asexuality.

Two problems come to mind:

1: What do “sexual fantasy” and “sexual activity” mean? Things that personally give me warm fuzzy feelings twinges of pain that I think were meant to be warm fuzzy feelings but the wires got crossed, or things that would normally be called sexual? Because there’s no overlap between those two categories at all.

2: Answering “No” to the question of “Would you ever willingly have sex with someone of the opposite gender?” requires you to claim you’re either gay or straight. There’s no plain “No”. It didn’t actually object when I skipped that question, though, despite not explicitly saying it wouldn’t (unlike the ideal relationship questions).

…why yes I am following you preemptively. (It’ll be weird, because I tend to think of Internet people as beings comprised purely of text and the occasional GIF. No matter what face they…

I tend to imagine Internet people’s appearances the same way I do with characters in books, dreams, or other things where I haven’t seen them otherwise. There’s a basic body shape, possibly skin and hair colour*, and if they’re very lucky they’ll get some defined clothes as well. It doesn’t seem as weird as it sounds when I put it that way. I hear some of it’s a prosopagnosic thing.
