A new study led by researchers at MIT suggests that fasting and then refeeding stimulates cell regeneration in the intestines, reports Katharine Lang for Medical News Today. However, notes Lang, researchers also found that fasting “carries the risk of stimulating the formation of intestinal tumors.”
Prof. Ömer Yilmaz and his colleagues have discovered the potential health benefits and consequences of fasting, reports Max Kozlov for Nature. “There is so much emphasis on fasting and how long to be fasting that we’ve kind of overlooked this whole other side of the equation: what is going on in the refed state,” says Yilmaz.
MIT researchers have discovered how fasting impacts the regenerative abilities of intestinal stem cells, reports Ed Cara for Gizmodo. “The major finding of our current study is that refeeding after fasting is a distinct state from fasting itself,” explain Prof. Ömer Yilmaz and postdocs Shinya Imada and Saleh Khawaled. “Post-fasting refeeding augments the ability of intestinal stem cells to, for example, repair the intestine after injury.”
Falmouth’s Ben & Bill’s Chocolate Emporium has unveiled a new chocolate candy named Dr. Bob’s Dark Chocolate Maple Syrup Cream – inspired by Prof. Bob Langer’s love of maple, reports Jon Chesto in The Boston Globe. “To make the Dr. Bob’s candy, the staff takes the maple cream chocolates and then drizzles maple syrup over them as a topping,” writes Chesto.
Plonts, a plant-based cheese company co-founded by Nathaniel Chu PhD '19, uses microbes to develop “nutritious, inexpensive and sustainable” cheese alternatives, reports Christine Hall for TechCrunch. Chu says “microbes, whether mold, bacteria or yeast, are important to create that flavor. The microbes themselves are tiny sacs of hundreds of different enzymes with many different combinations,” writes Hall.
Research Scientist Christopher Mejia-Argueta is interviewed by Marina Mayer of Food Logistics about the food industry’s efforts to achieve a circular supply chain, which could help companies improve their sustainability. “Despite a growing trend to improve the food supply chains from farm to fork and back to farm, scalability is the biggest challenge,” he says.
Prof. Kripa Varanasi and Vishnu Jayaprakash SM '19, PhD '22 founded AgZen, a company aimed at reducing pesticide use by employing a feedback-optimized spraying system, reports Steven Savage for Forbes. Savage notes that for the researchers behind AgZen, “MIT turned out to be a good place to work on the specific imaging technology and on the AI needed to translate that into a practical solution for farmers.”
MIT researchers have developed “a robotic system that can rotate different types of fruit and vegetable using its fingers on one hand, while the other arm is made to peel,” reports Alex Wilkins for New Scientist. “These additional steps of doing rotation are something which is very straightforward to humans, we don’t even think about it,” Prof. Pulkit Agrawal. “But for a robot, this becomes challenging.”
Visiting Scientist Ariel Ekblaw speaks with Scientific American’s Andrew Chapman about a microgravity water cooker called the H0TP0T, part of a mock space habitat set to open in Boston in early August. For the project “Ekblaw and a colleague interviewed nearly two dozen astronauts—who often mentioned better cooking options and tastier food as important ways to improve their well-being,” Chapman explains.
Using multimodal sensing and a soft robotic manipulator, MIT scientists have developed an automated system, called RoboGrocery, that can pack groceries of different sizes and weights, reports Brian Heater for TechCrunch. Heater explains that as the soft robotic gripper touches an item, “pressure sensors in the fingers determine that they are, in fact, delicate and therefore should not go at the bottom of the bag — something many of us no doubt learned the hard way. Next, it notes that the soup can is a more rigid structure and sticks it in the bottom of the bag.”
Researchers from MIT have developed RoboGrocery, a soft robotic system that “can determine how to pack a grocery item based on its weight, size and shape without causing damage to the item,” reports Jennifer Kite-Powell for Forbes. “This is more than just automation—it's a paradigm shift that enhances precision, reduces waste and adapts seamlessly to the diverse needs of modern retail logistics,” says Prof. Daniela Rus, director of CSAIL.
Prof. Bob Langer and Prof. Giovanni Traverso have co-founded Syntis Bio, a biotech company that will use technology to “coat the stomach and potentially other organ surfaces, [change] the way that drugs are absorbed or, in the case of obesity, which hormones are triggered,” reports Allison DeAngelis for STAT.
Writing for The New York Times, Kenji López-Alt '02 slices into his research with Rui Viana '05 on the best method for cutting an onion. Using “computer models of the cross section of an onion,” López-Alt and Viana simulated “various cutting geometries and to calculate basic information, such as the number of pieces cut with each method, their average size and the standard deviation from the norm within that group" to see which method is a cut above the rest.
MIT have developed a new ingestible vibrating capsule that could potentially be used to aid weight loss, writes Newsweek’s Robyn White. Prof. Giovanni Traverso said the capsule “could facilitate a paradigm shift in potential therapeutic options for obesity and other diseases affected by late stomach fullness.”
Prof. Kripa Varanasi and Vishnu Jayaprakash SM '19, PhD '21 co-founded AgZen, an MIT spinoff that is developing new technologies to improve the performance and effectiveness of pesticide treatments, reports The Economist. The new technologies “could reduce the total amount of fungicides and insecticides sprayed over complete crops by some 90%, as well as cutting the amount of adjuvants required,” writes The Economist.
