Researchers in the Department of Mechanical Engineering used fossil evidence to engineer a soft robotic replica of pleurocystitids, a marine organism that existed nearly 450 million years ago and is believed to be one of the first echinoderms capable of movement using a muscular stem.

Eco-friendly conductive ink promises to revolutionize the production of soft stretchable electronic circuits

Researchers at the Faculty of Science and Technology of Universidade de Coimbra (FCTUC) and Carnegie Mellon University have developed a water-based conductive ink tailored for producing flexible electronic circuits. The technique, developed with Carnegie Mellon Portugal Program's (CMU Portugal) support, sidesteps the necessity of employing conventional organic solvents, renowned for their detrimental environmental impact due to pollution and toxicity. The results have been published in the journal Advanced Science. By being water-based, this ink is more sustainable and ecological and significantly reduces the environmental impact of existing solutions. On-skin bio stickers to monitor patients' health or recyclable smart packages with integrated sensors for monitoring the safe storage of perishable foods are among the possible uses. Manuel Reis Carneiro, a doctoral student from the CMU Portugal, is part of the team led by Mahmoud Tavakoli, which already has extensive experience developing stretchable electronic circuits efficiently, quickly, and cheaply.

cmu puzzle hunt spring 2024 is a wrap :) i had a lot of fun with it as well! the team i hunted with got 8th place which is higher than any team i've been on before

i contributed the bookshelf of tchotchkes that is featured in the wrapup which i won't paste here because it's full of hunt spoilers

if you're thinking of solving it, the tiling room round is quite a nice round that shouldn't be too hard (except maybe the cryptics :/). and the diy room round was a proper doozy

now maybe i should actually get some work done

Does it count as conflict of interest if the HR Person in charge of my hiring also gets a bonus if I’m hired? Carnegie Mellon has some weird policies

#legal #legal advice #university #carnegie mellon university #Human Resources #im steamed bc i got lied to and THEN realized that there was in fact motive #law help #university help #edit: so I was told the wrong location for my job by this hr person #which lasted until a week before my hire #no I don’t have written evidence #I’m not tryna pin them on miscommunication #im curious if conflict of interest applies when their decision making stands to benefit them financially #or if this is totally legit

📝 Editorial: Some Cool Details About Llama 3

I had an editorial prepared for this week’s newsletter, but then Meta AI released Llama 3! Such are the times we live in. Generative AI is evolving on a weekly basis, and Llama 3 is one of the most anticipated releases of the past few months.

Since the debut of the original version, Llama has become one of the foundational blocks of the open source generative AI space. I prefer to use the term “open models,” given that these releases are not completely open source, but that’s just my preference.

The release of Llama 3 builds on incredible momentum within the open model ecosystem and brings its own innovations. The 8B and 70B versions of Llama 3 are available, with a 400B version currently being trained.

The Llama 3 architecture is based on a decoder-only model and includes a new, highly optimized 128k tokenizer. This is quite notable, given that, with few exceptions, most large language models simply reuse the same tokenizers. The new tokenizer leads to major performance gains. Another area of improvement in the architecture is the grouped query attention, which was already used in Llama 2 but has been enhanced for the larger models. Grouped query attention helps improve inference performance by caching key parameters. Additionally, the context window has also increased.

Training is one area in which Llama 3 drastically improves over its predecessors. The model was trained on 15 trillion tokens, making the corpus quite large for an 8B parameter model, which speaks to the level of optimization Meta achieved in this release. It’s interesting to note that only 5% of the training corpus consisted of non-English tokens. The training infrastructure utilized 16,000 GPUs, achieving a throughput of 400 TFLOPs, which is nothing short of monumental.

Llama 3 is a very welcome addition to the open model generative AI stack. The initial benchmark results are quite impressive, and the 400B version could rival GPT-4. Distribution is one area where Meta excelled in this release, making Llama 3 available on all major machine learning platforms. It’s been just a few hours, and we are already seeing open source innovations using Llama 3. The momentum in the generative AI open models space definitely continues, even if it forced me to rewrite the entire editorial. 😊

From 2D to 3D: MXene's path to revolutionizing energy storage and more

With a slew of impressive properties, transition metal carbides, generally referred to as MXenes, are exciting nanomaterials being explored in the energy storage sector. MXenes are two-dimensional materials that consist of flakes as thin as a few nanometers. Their outstanding mechanical strength, ultrahigh surface-to-volume ratio, and superior electrochemical stability make them promising candidates as supercapacitors—that is, as long as they can be arranged in 3D architectures where there is a sufficient volume of nanomaterials and their large surfaces are available for reactions. During processing, MXenes tend to restack, compromising accessibility and impeding the performance of individual flakes, thereby diminishing some of their significant advantages. To circumvent this obstacle, Rahul Panat and Burak Ozdoganlar, along with Ph.D. candidate Mert Arslanoglu, from the Mechanical Engineering Department at Carnegie Mellon University, have developed an entirely new material system that arranges 2D MXene nanosheets into a 3D structure.

The Weight of the Inside of the Body

Saskia Hamilton, 1967–2023

Last week was Pongo Poetry Project's annual gala/fundraiser, Speaking Volumes, and during the event the guest poets—Arianne True, Shin Yu Pai, and Quenton Baker—were asked to name someone who was influential to their writing and their interest in poetry.

As the poets talked, I thought about Saskia Hamilton, who died this past summer at only 56. What a terrible loss.

It's both a blessing and a curse to be less extremely online than I once was.* On the one hand, social media can be corrosive; on the other hand, social media can help one stay on top of the news. I only heard about Saskia's death a few weeks ago, when I logged into Instagram for the first time in ages (somehow I'd missed the Times obit). I was, to put it mildly, super bummed.

Saskia was the first writing teacher I really looked up to—I took a workshop with her when she was at Kenyon between 2000–2001—and though we fell out of regular touch, I eagerly read her books as soon they were published.

In addition to being a talented poet and editor, Saskia was, more importantly when I was 20/21 years old, cool: she invited our workshop to her apartment in Mt. Vernon one night, and I drank a Grolsch; she grew up with Guy Picciotto of Fugazi (my favorite band!!!) & so knew the band well & we drove from Gambier to Carnegie Mellon to see them play one Saturday morning (something I've written about previously); when she taught at Kenyon she tended to wear lots of black, effortlessly; and when I was applying to grad school, she told me to stay in NYC and not decamp for Minnesota, advice I ignored. Maybe I shouldn't have?

The older I get, the more of my heroes I say goodbye to. The good news, amen, I suppose, is that their work remains, and with it some small part of them. Here's her poem "Zwijgen," from Corridor:

I slept before a wall of books and they calmed everything in the room, even their contents, even me, woken by the cold and thrill, and still they said, like the Dutch verb for falling silent that English has no accommodation for in the attics and rafters of its intimacies.

...

*Thanks to Musk & Zuckerberg—erstwhile combatants—for driving me from their respective websites.

Title taken from Saskia's poem of the same name, which opens her collection Divide These.
