Researchers at MIT have developed a new physical model that can help “improve predictions of proton mobility across a wide range of metal oxides,” reports Ameya Paleja for Interesting Engineering. “This can help develop new materials and technologies powered by protons as charge carriers, rather than relying on lithium, which is widely used now,” explains Paleja.
MIT researchers have developed “GelSight,” a system that provides robots with a sense of touch, reports Ben Guarino for Scientific American. “GelSight can identify by touch the tiny letters spelling out LEGO on the stud of a toy brick,” explains Guarino.
MIT researchers have developed a deep-learning model “capable of predicting the precise movements, divisions, and restructuring of thousands of cells during the embryo’s transition from a simple cluster to a complex organism,” reports Mrigakshi Dixit for Interesting Engineering. “This model currently provides a sneak peek into the fruit fly’s earliest developmental stage,” explains Dixit. “In the future, it could be used to predict how more complex tissues, organs, and organisms develop.”
Sherwin Greenblatt '62, SM '64 reflects on his two-decade tenure as director of MIT’s Venture Mentoring Service (VMS), a program that provides support for entrepreneurs in the MIT community, reports Jon Chesto for The Boston Globe. “VMS differs from many mentoring programs in that entrepreneurs are connected to not just one mentor, but several subject matter experts, depending on their needs,” explains Chesto. “These are also considered long-term commitments, not just several months of counsel and brainstorming.”
While studying a 2,000-year-old construction site in Pompeii, MIT researchers uncovered new insights into the Roman building process, including the key ingredients needed to develop long-standing durable Roman concrete, reports Luis Prada for Vice. “Ancient Roman builders were ‘hot-mixing,’ which means that they dumped volcanic ash and powdered quicklime together dry, then added water later, triggering a chemical reaction that cooked the mixture from the inside,” writes Prada.
A new paper by Prof. Admir Masic and his colleagues details their new findings on the specific ingredients used by ancient Romans to develop durable concrete, reports Sarah Kuta for Smithsonian Magazine. “Looking ahead, the findings could help improve modern construction techniques, informing the development of next-generation durable, low-carbon concrete,” writes Kuta.
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.
Prof. James Collins and his colleagues are using AI to develop new compounds to combat the growing problem of antibiotic resistant bacteria, reports Lisa M. Krieger for the San Francisco Chronicle. Thus 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. 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. 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.”
A new report co-authored by Prof. Dava Newman and Lindy Elkins-Tanton '87, SM '87, PhD '02 explores the highest-priority science objectives for the first human missions to Mars, reports Eric Berger for Ars Technica. “We’re searching for life on Mars. The answer to the question ‘are we alone’ is always going to be ‘maybe,’ unless it becomes yes,” explains Newman.
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.”
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.”
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,”
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.”
