The concrete and cement sector has been trying to reduce its environmental impact for years through sustainable concrete mixtures or efficient designs.

Now, a research team at the University of Pennsylvania has combined both novel materials and a material-saving design, without compromising on strength and durability.

The project, called Diamanti, takes inspiration from nature and uses a robotic 3D printer to create complex, lattice-like patterns with a sustainable concrete mixture.

While most regular concrete absorbs carbon dioxide (up to 30% of its production emissions over its entire life cycle, according to some research), Diamanti’s enhanced concrete mixture absorbs 142% more carbon dioxide than conventional concrete mixes.

Its first design, a pedestrian bridge, uses 60% less material while retaining mechanical strength, says Masoud Akbarzadeh, an associate professor of architecture at the University of Pennsylvania and director of the lab that spearheaded the project.

    True, but that is isn’t one most people think about from the originals. I think Aliens is the most remembered. To the point I think people forget the original is creeping horror and not action

        People around here shocked by the mention of pubes, uh? (even though I’m commenting on a scene of the movie they were talking about)
        How can I know if it was a community or instance mod, though? I want to be sure which to block so I don’t make the mistake of commenting on a puritan forum again.

      I was never a huge fan of the franchise, as I hate horror, but when you’re young, you want to fit in, so you hear “oh, it’s not at all like the first one” and think “well, worth a shot.” Also, I have a thing for chicks with extremely short hair, so there may be some confirmation bias in my memory.

        Do you always talk about women like this? Chicks? Definitely a way to show that you don’t respect them…

          I don’t know … I picked up using the term from my ex-wife. That’s what she referred to women as.

            Idc, in certain contexts said by certain people maybe it’s ok. But as a usual way to talk about women as “chicks” or also the widely used “females” is demeaning and is rooted in misogyny. I’d think language can be powerful and we should reflect upon why we use certain words and what that tells us about our underlying worldview.

              I’m sorry, but if your starting point is “idc,” you’ve given up any interest in a productive conversation. Don’t expect that of me if you’re not available. You get to choose one. Either victim or feminist warrior, but you can’t be both.

              But your literal starting point is “I don’t care.” If you don’t care, you don’t post. Simple as that. You’re lying in one way or the other, and it’s really not something I care about. I’ll take you seriously when you can express consistent thoughts, but I’m still going to be irritated that you caused an entire mod conversation because – and I know you won’t care – you give no shits about anyone on here. You just wanted to whine and destroyed years of goodwill as the lines were drawn because of your actions.

              Great to not care. You get to sleep as though nothing happened. You fucked up a consistent baseline. I hope that makes you happy.

                No, you misunderstood what I was saying. I don’t care where you picked it up from or in what context your wife uses it. It doesn’t matter because what we were in fact discussing where you talking about women by using the word “chicks”.

                Even if 30 years ago you and your friends used words like the n-word or slurs for all kinds of minorities (various very widespread examples for disabled, trans, gay or Jewish people come to mind), the world is changing.

                I simply don’t care about your feelings of having to adapt by not using discriminatory or demeaning speech. It’s really not that hard to do, if you actually wanted to…

                What I do care about a lot is that we should be working on making this a safe environment for all everyone. What worries me, is that you are a beehaw user as well.

                  You’re really going with this being as bad as the N-word? I mean, I get you don’t like the term, but that’s false equivalence. I’ve gotten an earful on this from other mods and admins, so, point taken.

                  But get off your high horse. There was nothing demeaning or discriminatory about that usage. If you choose to believe there was, that’s on you. Communication requires a sender and a receiver, and in this case, you were looking for outrage in an innocuous setting, found it, and turned a one-off into a federal case. “Short-haired women” sounds idiomatically wrong, and I just searched my own history for use of the word “chick.” I’ve been using it on Beehaw for two years, and you’re the first person to have had a problem with it.

                  You’re making a number of assumptions about both me and my idiolect. This being a safe space doesn’t mean hypercorrecting so that you feel safe and others feel attacked. Just look at how far off the rails we are from the actual topic so you can go off on a holier-than-thou excursion. I hope you’re happy that you caused hours of argument because you somehow felt personally attacked by a movie reference.

                    I feel like you similarly project a lot onto me right now. I didn’t say using the word “chick” is as bad as the n-word. And I’m also not super mad about you using it. In fact, I tried to just casually point out that it’s not the coolest word to use. The problem is, and here I brought in a similar discussion led when talking about slurs, that it is often very tedious to discuss with privileged people who cling to those words because they don’t want to give up the freedom to use those terms. These kinds of discussions tend to be less constructive and more heated. It seems you are very defensive about this yourself, otherwise, why would you write multiple long responses about it?

                    In short, sorry, if I came off super aggressive. I really just meant it to be a friendly reminder, that we should from time to time check our language and that in my eyes “chick” is a very demeaning term. Do what you want with it, I would feel safer in this community, if you’d stop using “chick” to talk about women.

            Actually, given more time to think about it, I picked it up from the chick who took me to my first rave in 1997. So I actually have nearly 30 years (my 45-year-old ex still uses the term) of evidence that this is an acceptable term for women.

            Maybe go clutch a different pearl if you’re here just to find outrage. It’s slang and neither vulgar nor demeaning. Wrong C-word to challenge for referring to women.

              A whole lot of women and femmes dislike that word because it is condescending and dehumanizing. Just because 2 people in your life don’t think so doesn’t mean a majority of people don’t.

                Also worth noting: In 1997, “girls” was demeaning, but 18-year-olds didn’t feel like “women,” and as such, “chicks” came into play. It was never demeaning, just the sort of ahead-of-time thing that finally got us to singular “they.”

                I mean, if you want you view it as dehumanizing and condescending, that is of course your right. And as we’ve generally gotten along well, I don’t like that we have to disagree here.

                I was providing bookends, not two data points. Among the circles I’ve run in since that start in college, no one has found it offensive. This is manufactured outrage, to my mind.

                Like, this sort of tone policing is how people who are otherwise reasonable start to feel alienated. I can’t use a word from my decadeslong lexicon because you view it differently? Fuck off with that. Those marginally offended and not directly addressed have the choice to not engage in the conversation. “Oh, this guy’s, a misogynist prick; no point in talking” is a perfectly reasonable response.

                But don’t tell me this is a universally hated term that’s a tell for viewing women as inferior, because you don’t have the receipts. It’s like claiming “dude” is demeaning because it implies I work on a ranch.

                It’s slang. You want to co-opt that to show the oppression of the patriarchy? Fine. I feel no guilt using a term women around me have for decades. I’m going to call snowflake shit on the left just as much as on the right. You’re literally trying to claim my intent without context or, you know, being in my own brain, and that’s not particularly nice.

                  The information is pretty easy to find, but since you asked for receipts, here is a article from JSTOR that calls out “chick” as a dehumanizing term for women and cites a study from the 90s that calls it out (among several other dehumanizing words for women).

                  https://daily.jstor.org/the-language-of-nasty-women-and-other-gendered-insults/

                  I think you misinterpret the point of me calling out the word. I don’t think you have an intention to condescend or dehumanize women, but other people that use “chicks” to refer to women often do. If it were me, I would not want to associate myself with them.

                  In the end, intent matters less than impact. For example, if you use a slur that you did not know was a slur, wouldn’t you rather be told so you can stop using it?

                    I of course would if told that’s a problem. The failure, as I see it, is that “chicks” only came into my lexicon via women. If they’re using the term, how am I being offensive?

                    This feels like manufactured grievance. I present an excerpt from an email I received from the woman who got me into the rave scene many moons ago:

                    damn [Powderhorn]! you’re braver than i shall ever be. remember to follow the sunset- not the sunrise. it can only blind you and lead you where only the teachers and preachers want you to be. always take that shadowed path… that is where you will find happiness. not many find it there, but you are one of those few - i know. whether it be early in the morning, downtown in a strange place with some bizzare chick … good traveling. this is your life. i am so jealous that you are taking it upon yourself to be your own life. someday i will be that brave… i wish you all the luck in the world… your friend forever

                    Now, we can play this game that I hate women, but it’s not going to have a lot of legs.
