Nature reporter Rachel Fieldhouse spotlights graduate student Lauren 'Ren' Ramlan’s work integrating the video game Doom into her research. Ramlan used “Escherichia coli bacteria to display a few frames of Doom,” explains Fieldhouse. “She attached a fluorescent protein to the bacterial cells that could be turned on or off, making them act like black and white pixels on a screen. She then translated and compressed the first few frames of Doom into black-and-white versions that matched the plate growing the cells. Ramlan says the project shows what living things can be engineered to do, and that bacteria are probably not suitable for computing or displaying images.” 

Graduate student Verena Bellscheidt has been awarded the Zonta Club of Wuaboag Valley Women in STEM award, reports The Republican. Bellscheidt is “dedicated to advancing the field [of theoretical physics] at the intersection of cosmology and particle physics while mentoring the next generation of female scientists.” 

Postdoctoral Fellow Florian Galleri speaks with Associated Press reporter Sylvie Corbet about France’s move to align “its nuclear deterrent strategy more closely with European allies while keeping full control over any strike decision.” Galleri says “the strategic backing intended to integrate French nuclear deterrence into a collective European defense framework necessarily requires a degree of coordination and joint planning.” 

Prof. Anna-Christina Eilers and postdoctoral associate Rohan Naidu speak with Scientific American reporter Rebecca Boyle about the discovery and study of Little Red Dots, mysterious, red spots that showed up in images from the James Webb Space Telescope.  The dots, which astronomers dated to 600 million years after the big bang, “are in every single image the telescope takes,” says Naidu. “We have to find out about them if we want to tell a complete story about the early universe." 

Graduate student Clarke Cyrus and his colleagues have developed “the Anemoia Device,” a physical machine that “uses a generative AI model to analyze an archival photograph, describe it in a short sentence, and, following the user’s own inputs, convert that description into a unique fragrance,” reports Grace Snelling for Fast Company. “Generative AI usually starts with a blank prompt,” says Clarke. “The dials replace that with a physical, easy-to-understand grammar. You’re not trying to ‘say the right thing’ to an algorithm, it’s more akin to tuning an instrument." 

Researchers at MIT have “developed a new technique that enables large language models to learn new skills and knowledge without forgetting their past capabilities,” reports Ben Dickson for Venture Beat. “Their technique, called self-distillation fine-tuning (SDFT), allows models to learn directly from demonstrations and their own experiments by leveraging the inherent in-context learning abilities of modern LLMs,” explains Dickson. “Experiments show that SDFT consistently outperforms traditional supervised fine-tuning (SFT) while addressing the limitations of reinforcement learning algorithms.” 

Using the James Webb Telescope, postdoctoral associate Rohan Naidu and his colleagues have captured a glimpse of Galaxy MoM-z14, which existed 280 million years after the Big Bang, and could provide clues as to what the universe was like during its infancy and how it has evolved over time, reports Passant Rabbie for Gizmodo. “We can take a page from archeology and look at these ancient stars in our own galaxy like fossils from the early universe,” says Naidu. “Except in astronomy we are lucky enough to have Webb seeing so far that we also have direct information about galaxies during that time.” 

Postdoctoral Associate Fatima Husain speaks with National Geographic reporter Theo Nicitopoulos about the various theories used to explain how living creatures survived the Cryogenian era. “These surface settings could have enabled a diverse assemblage of life to persist and continue to evolve throughout the glaciations,” says Husain. “We keep learning more about how extreme the Cryogenian was… and that makes life persisting and diversifying dramatically after that, all the more amazing.” 

Writing for The Boston Globe, graduate student Jonah Prousky highlights the benefits and drawbacks of social media bans, and ways to protect kids from online harms. “We likewise need a cultural reckoning on screen time for kids, since heavy use is associated with anxiety, depression, attention fragmentation, and sleep deprivation,” writes Prousky. “Australia demonstrated that a law can be used to get the ball rolling.” 

Graduate student Stephen Casper speaks with Wired reporter Matt Burgess about the rise of “deepfake video abuse and its role in nonconsensual intimate imagery generation.” “This ecosystem is built on the back of open-source models,” says Casper. “Oftentimes it’s just an open-source model that has been used to develop an app that then a user uses.” 

A new analysis conducted by postdoctoral associate Rohan Naidu and his colleagues has found evidence that suggests “little red dot” galaxies may contain baby black holes, reports Alex Wilkins for New Scientist. “In ordinary black holes, what you actually see with your eyes is the tip of the iceberg of the total energy that is coming out of the system, but the little red dots we now understand should really be thought of as these puffed-up black hole stars,” says Naidu. “It seems that most of their energy is coming out at these wavelengths that we see with our eyes, so what you see is what you get.” 

Alumnus Jerry Lu and his colleagues have developed OOFSkate, an AI-powered app that can analyze a figure skater’s “jump height, rotation speed, airtime and even landing quality,” reports Dave Skretta for the Associated Press. “Our vision for the system is to automate the technical calling of the sport,” says Lu. “This manifests itself in a combination of using AI-assisted computer vision, but also the knowledge of figure skating, essentially taking out the stuff that should be judged without subjectivity.”

New York Times reporter Catherine Porter spotlights Roofscapes, an MIT startup founded by Olivier Faber MArch '23, Tim Cousin MArch '23 and Eytan Levi MArch/MSRED '21 that aims to transform the zinc-roofed buildings in Paris into accessible green spaces as part of an effort to decrease building temperatures while improving quality of life. “We have an opportunity with all these untouched surfaces to do something that is virtually impossible anywhere else in a city like Paris,” explains Levi. “There’s a new way you can live.”

After observing the collision between a supernova and a black hole, researchers at MIT and elsewhere are rethinking our understanding of the life and death of stars, reports Jeanine Santucci for USA Today. "One of the only reasons that we were able to make this discovery and understand how scientifically interesting it was was through the combination of researchers in machine learning and in astrophysics," says postdoctoral scholar Alex Gagliano. 

With the help of a newly designed machine learning algorithm, researchers at MIT and elsewhere have spotted a “never-before-seen type of supernova that involves a nearby black hole,” reports Andrew Paul for Popular Science. “We’re now entering an era where we can automatically catch these rare events as they happen, not just after the fact,” said postdoctoral scholar Alex Gagliano. “That means we can finally start connecting the dots between how a star lives and how it dies, and that’s incredibly exciting.”
