There's One Surviving Copy of This Tale of King Arthur's Knights. A Researcher Just Unlocked Its Secrets.

An MIT professor discovered that the Pearl Manuscript from the 1300s has more to it than just four unconnected medieval poems.
Professor Arthur Bahr found that along with the tale 'Sir Gawain and the Green Knight,' the poetry-filled book features plenty of additional aspects far beyond merely words on a page.
Bahr has a new book covering the unique aspects of Sir Gawain and the other three poems in the Pearl Manuscript.
When MIT literature professor Arthur Bahr spent some time with the manuscript officially dubbed 'British Library MS Cotton Nero A X/2,' it opened his eyes to the mysteries surrounding the legendary tale 'Sir Gawain and the Green Knight.'
The single-bound volume—know more commonly as the Pearl Manuscript—is easily best known for being the only written source of the most famous story of one of King Arthur's most famous Knights of the Round Table. It dates to the 1300s and, alongside the story of Sir Gawain, includes the only surviving copies of three other medieval poems—'Pearl,' 'Cleanness,' and 'Patience.'
Many medieval bound volumes were simply different documents bound together—something that has long been fascinated Bahr. But, according to his recent analysis, the Pearl Manuscript is much more than just words on paper.
'My argument is that this physical object adds up to more than the sum of its parts, through its creative interplay of text, image, and materials,' Bahr said in a statement. 'It is a coherent volume that evokes the concerns of the poems themselves. Most manuscripts are constructed in utilitarian ways, but not this one.'
Bahr undertook a complete re-examination of the tome, complete with spectroscopic analysis and mathematical investigation, to try and understand this historic text more entirely. In the process, Bahr discovered some of its secrets, which he put together in his own book, 'Chasing the Pearl-Manuscript: Speculation, Shapes, Delight.'
'The more you look,' he said, 'the more you find.'
And there was plenty to find. To start, through the spectroscopic analysis—an examination technique in which different wavelengths of light are used to investigate an object—Bahr was able to show that the volume originally featured simple line drawings that were later filled in with colored ink. Additional study of the physical manuscript (rather than the digital images) allowed him to see that the parchment on which these drawings were created was animal skin.
Animal hide was not an uncommon material for books to be crafted from at the time—in fact, that's what 'parchment' is. What is uncommon, however, is the particular way in which the parchment was used in the 'Patience' poem. The piece is a reworking of the biblical story of Jonah (the man who survived being swallowed by a whale), and perhaps to provide a more visceral experience for the reader, the parchment was reversed so that the 'hair' side of the material faced the reader rather than the 'flesh' side (as is the case with the other three poems).
'When you're reading about Jonah being swallowed by the whale, you feel the hair follicles when you wouldn't expect to,' Bahr said. 'At precisely the moment when the poem is thematizing an unnatural reversal of inside and outside, you are feeling the other side of another animal
As for the the tale of Sir Gawain—who was not only a member of King Arthur's legendary Round Table, but the king's nephew—it comes alive thanks to a combination of the parchment's textures, poems' construction, and intricate illustrations.
'It's a very MIT kind of poem in the sense that not only is the author, or authors, obsessed with math and geometry and numbers and proportion, they are also obsessed with artifact construction, with architectural details, and physical craft,' Bahr said. 'There's a very 'mens et manus' [mind and hand] quality to the poems that's reflected in the manuscript.'
While the authorship of each of the poems is unknown, most experts believe every piece contained within the Pearl Manuscript was written by the same person. Sequentially, the manuscript starts with 'Pearl,' followed by 'Cleanness,' 'Patience,' and ending with 'Sir Gawain and the Green Knight,' which Bahr described as an eerie, surreal tale of courage and chivalry.
Bahr said that not only are the four texts thematically linked, but when looked at together the 'manuscript starts to cohere into a wrought, imperfect, temporally layered whole.'
The tome is also, it turns out, surprisingly mathematical. For instance, both 'Pearl' and 'Sir Gawain' are written to be exactly 101 stanzas long, which Bahr believes is an intentional imperfection, as a 'perfect' poem would have 100 stanzas even. 'Pearl' is based around the number 12, with all but one of its stanzas featuring 12 lines—another proposed intentional imperfection. There are also 36 lines per page throughout the entirety of the manuscript (notable in a time when books were written by hand and could have as many or as few lines on a page as the writer wished), and both 'Pearl' and 'Sir Gawain' possess numerically consistent structures.
Daniel Wakelin of Oxford University said in a statement that Bahr's take presents 'a bold model for studying material texts and literary works together.'
Bahr believes that the medieval reading experience was determined by how the reader interacted with the book itself. 'Materiality matters,' he said. Taken as a whole, Bahr said that from a knight at the round table to 'Pearl,' this bound volume from the 1300s is a more complex piece of visual and textural art than anyone had ever seen before.

I co-wrote the anonymous HHS report on pediatric gender medicine

Alex Byrne is a professor of philosophy at MIT. In May, the Department of Health and Human Services published a comprehensive review of treatments for gender dysphoria in minors that was swiftly criticized, in part because the names of its authors were withheld. I am one of the authors. As Health and Human Services said upon publication, the review is going through the peer review process, for which anonymity is preferred. My co-authors and I discussed additional reasons for anonymity, including that disclosure might distract attention from the review's content or lead to personal attacks or professional penalties. Those who have raised concerns about the field of pediatric gender medicine are well aware of the risks to reputations or careers.

ChatGPT could be silently rewiring your brain as experts urge caution for long-term use

Using ChatGPT on a long-term basis could have negative effects on brain function. That's according to a study led by the Massachusetts Institute of Technology (MIT), which found that using a large language model (LLM) to write multiple essays over a four-month period could hamper cognitive abilities. In the study, 54 participants were divided into three groups. Woman Says Chatgpt Saved Her Life By Helping Detect Cancer, Which Doctors Missed One group used ChatGPT, an LLM product made by OpenAI, to write an essay. The second group used only a search engine, and the third group used only their own brains, according to a press release from MIT. Read On The Fox News App The participants underwent three sessions where they completed the same assignment. Then, in the fourth session, the LLM group was asked to write an essay without any tools, and the "brain-only" group was asked to use an LLM for assistance. During each session, the researchers recorded the participants' brain activity using an EEG monitor to assess their "cognitive engagement and cognitive load" and to determine their neural activity, the release stated.

Human teachers and an artificial intelligence agent scored the assessments. "EEG analysis presented robust evidence that LLM, search engine and brain-only groups had significantly different neural connectivity patterns, reflecting divergent cognitive strategies," the researchers wrote. Participants showed less brain connectivity when they used the tools to help write their essays, the study found. "The brain‑only group exhibited the strongest, widest‑ranging networks; the search engine group showed intermediate engagement; and LLM assistance elicited the weakest overall coupling," the researchers wrote. In the fourth session, the participants who switched from LLM to brain-only showed "weaker neural connectivity" and less cognitive engagement. The LLM group also had less ability to recall information from the essays they had just written. Those who switched from brain-only to LLM had "higher memory recall" and greater cognitive engagement. Based on these findings, the researchers said there could be a "possible decrease in learning skills" among LLM users. "The use of LLM had a measurable impact on our participants, and while the benefits were initially apparent, as we demonstrated over the course of four sessions … the LLM group's participants performed worse than their counterparts in the brain-only group at all levels: neural, linguistic [and] scoring," they wrote. The findings have been uploaded to Arxiv, a preprint service, but have not yet been peer-reviewed, as the researchers noted that "all conclusions are to be treated with caution and as preliminary." There were also a limited number of participants who were all from the same geographical area. Ai Tool Scans Faces To Predict Biological Age And Cancer Survival "For future work, it will be important to include a larger number of participants coming from diverse backgrounds, like professionals in different areas and age groups, as well as ensure that the study is more gender-balanced," the researchers noted. Only ChatGPT was used in the study; future research could incorporate other LLMs. The EEG technology used to analyze brain connectivity could also have some limitations, as the researchers shared plans to use fMRI (functional magnetic resonance imaging) in future studies. "Our findings are context-dependent and are focused on writing an essay in an educational setting and may not generalize across tasks," they also stated. "Future studies should also consider exploring longitudinal impacts of tool usage on memory retention, creativity and writing fluency." Dr. Harvey Castro, an ER physician and "AI futurist" based in Texas, said he sees this study as a "neuro-wake-up call," especially for younger brains. "ChatGPT can make you 60% faster, but that speed comes at the price of neuro-engagement," Castro, who was not involved in the study, told Fox News Digital. "Brain connectivity collapses from 79 neural links to just 42, and 83% of users can't quote their own essays minutes later. Neuroplasticity research tells us developing brains will feel this hit hardest." In emergency medicine, Castro said, doctors call this "failure to encode." "The brain isn't processing and storing information," he said. "When neural connectivity drops by nearly half, we're looking at what researchers call 'cognitive debt.'" For medical students, an inability to encode and recall information under pressure could have serious implications for clinical decision-making, Castro noted.

Using LLMs for extended periods can be convenient, but could cause cognitive muscles to "atrophy" over time, the expert cautioned. There was one encouraging finding, however. "When people with strong foundational skills later used ChatGPT, they showed enhanced connectivity," Castro said. "The key isn't avoiding AI — it's building cognitive strength first." In education, he emphasized the need for periods of "AI-free cognitive development."

Medscape 2050: Robert Langer

Medscape 2050: The Future of Medicine Smart cells, artificial hearts, microneedles, a brain on a chip: These are just a few of the advances in biomedical engineering that Robert Langer, ScD, director of the Langer Laboratory at the Massachusetts Institute of Technology (MIT), envisions in the future. Langer's work blends biotechnology and materials science, and he is known for developing pioneering tech in the areas of drug delivery, tissue engineering, and regenerative medicine. Langer finds inspiration in the natural world, from geckos' feet to porcupine quills, as well as what he calls just 'basic research,' pursuing the burning question of 'how things work' with a mind open to discovery. Dream big, Langer says. 'If you could make a kidney from scratch, you wouldn't have to do a kidney transplant.' Or a heart, for that matter. But there are other fascinating avenues of study that can impact disease. By 2050, smart materials might sense blood sugar levels in a diabetes patient. Smart cells might seek out cancer cells and destroy them. Pills could shoot out tiny needles to deliver drugs to the stomach or intestine. 'The value of AI,' Langer predicts, 'will be pervasive' in making these leaps forward, analyzing chemical structures and histology or collecting data from inside the body. But the goal is collaboration across a range of disciplines. Take 'artificial intelligence, nanotechnology, immunology, materials science and put them together,' Langer recommends. This is how we change patients' lives.
