MassLive reporter Scott Kirsner spotlights Claire Beskin MBA '22, CEO and founder of Empallo, a virtual clinic for heart care aimed at preventing cardiac issues before they happen. “It handles everything from scheduling to prescriptions to billing,” writes Kirsner. “Empallo’s approach, Beskin said, is ‘virtual first,’ meaning it tries to give patients an online consult with a doctor when possible, and send them into the office when necessary.”
A study by MIT researchers examining the carbon emissions of self-driving cars found that “the power required to run one billion driverless vehicles driving for one hour per day could consume as much energy as all existing data centers in the world,” reports Claire Brown for The New York Times. Graduate student Soumya Sudhakar explains that another big unknown is how autonomous vehicles could change the way people travel, adding to the uncertainty over the overall long-term emissions outlook for self-driving cars.
Two new research papers by scientists from MIT and other institutions find that AI chatbots are successful at shifting the political beliefs of voters, and that the “most persuasive chatbots are those that share lots of facts, although the most information-dense bots also dole out the most inaccurate claims,” reports Sarah Kuta for Smithsonian Magazine. “If you need a million facts, you eventually are going to run out of good ones and so, to fill your fact quota, you’re going to have to put in some not-so-good ones,” says Visiting Prof. David Rand.
Prof. James Collins speaks with Financial Times reporter Patrick Temple-West about his work using AI to design new antibiotic compounds to combat drug-resistant bacteria. “At present, the [AI] models are doing quite well at designing compounds that can attack in a Petri dish,” says Collins.
Prof. James Collins and his colleagues are using AI to develop new antibiotic compounds to treat infections and combat antibiotic resistance concerns, reports Lisa M. Krieger for the San Fransico Chronicle. “Looking at the structure of a compound — bond by bond, substructure by substructure — it (AI) can make a calculation of the probability that it could be antibacterial,” explains Collins. So far, “Collins and his colleagues have synthesized several compounds that combat hard-to-treat infections of gonorrhea and MRSA,” writes Krieger. “These techniques are also being harnessed to fight diseases, like cancer, lupus and arthritis.”
Prof. Desirée Plata, director of MIT’s Methane Network, spoke with Boston Globe reporter Kate Selig about how regional supermarkets are addressing their methane footprints. Plata notes that “grocers could make an impact through improving their waste management practices. And beyond operational changes, she said supermarkets can help shape the public’s understanding of climate issues,” Selig writes. “Most people go to the grocery store,” says Plata. “They have this great opportunity to educate people.”
Prof. Jesse Thaler shares the physics moonshot experiment he would like to undertake if imagination was the only constraint on scientific ambition. “I am an enthusiast for an audacious idea to explore the unknown: a muon collider,” Thaler shares. “The muon is a brilliant candidate for a discovery machine. Muons are 200 times heavier than electrons, which makes them more efficient to accelerate. And unlike the protons used at the LHC, muons are elementary particles, so colliding them together would probe sharper, higher energies, potentially allowing us to discover more massive particles beyond the Higgs boson or even the nature of dark matter.”
MIT is “taking a quantum leap with the launch of the new MIT Quantum Initiative (QMIT), reports State House News reporter Katie Castellani. “There isn't a more important technological field right now than quantum with its enormous potential for impact on both fundamental research and practical problems,” said President Sally Kornbluth during the launch event. “QMIT will help us to ask the right questions, identify the most critical problems and create a roadmap for developing quantum solutions that are both transformative and accessible.”
While visiting a house that was under renovation when Mount Vesuvius erupted, MIT researchers were able to confirm the tools and ingredients used by ancient Romans to create long-lasting concrete, reports Humberto Basilio for Scientific American. “The hot mixing method creates fragmented, highly porous lime clasts within the mortar that allow calcium to easily travel through the material and recrystallize to fill cracks,” Basilio explains. “Understanding and mastering this “self-healing” technology will allow engineers to use the technique in modern construction.”
Prof. Admir Masic and his colleagues have confirmed that ancient Romans utilized “hot-mixing,” a technique that combines quicklime with volcanic rock, volcanic ash, and water, to create concrete that has lasted for thousands of years, reports Margherita Bassi for Gizmodo. “The team also discovered weights and measurement tools, which they propose may have been used to maintain concrete pouring ratios and build straight, even walls,” writes Bassi. “In short, the site revealed the clearest evidence yet of the ancient Roman use of hot-mixing in concrete.”
By studying a workshop that was buried in Pompeii almost 2,000 years ago, Prof. Admir Masic and his colleagues have uncovered how the ancient Romans created self-healing and long-lasting concrete, reports James Woodford for New Scientist. Masic and his team were stunned at how “exceptionally well preserved” the site was and that it offered an opportunity to understand Roman concreting methods in a way that “no laboratory reconstruction could ever replicate”. He adds: “The materials were exactly as they were at the moment the eruption froze the city in time,”
A new paper by Prof. Admir Masic and his colleagues reinforces his theory that the ancient Romans used a technique called “hot-mixing” to create concrete, reports Andrew Paul for Popular Science. “The evidence resides at an ancient Roman construction site preserved in great detail by the Mount Vesuvius eruption,” explains Paul. “Isotopic analysis confirmed that the workers in Pompeii relied on hot-mixing when making their concrete.”
Visiting Scientist Judah Cohen speaks with USA Today reporter Doyle Rice about how the polar vortex could send a blast over cold air to areas of the central and eastern United States. “I believe that the entire cycle of a weak or disrupted polar vortex that began at the end of November is coming to its conclusion by the end of next week,” explains Cohen. “Clearly, the polar vortex is strengthening and some period of milder weather in the central and eastern U.S. looks inevitable to me.”
President Sally Kornbluth is honored by The Boston Globe as one of the Bostonians of the Year, a list that spotlights individuals across the region who, in choosing the difficult path, “showed us what strength looks like.” Kornbluth was recognized for her work being of the “most prominent voices rallying to protect academic freedom.”
While analyzing samples from a newly-discovered construction site in Pompeii, researchers at MIT confirmed the ingredients and methods behind the ancient Romans’ durable and self-healing concrete, reports Will Dunham for Reuters. "Modern concretes generally lack intrinsic self-healing capability, which is increasingly important as we seek longer-lasting, lower-maintenance infrastructure," explains Prof. Admir Masic. "While the ancient process itself is not a direct replacement for modern standards, the principles revealed can inform the design of next-generation durable, low-carbon concretes."
