MIT researchers have developed an “Oreometer” to test the optimal way to split an Oreo cookie, an exercise in rheology, or the study of how matter flows, reports Isaac Shultz for Gizmodo. "Our favorite twist was rotating while pulling Oreos apart from one side, as a kind of peel-and-twist, which was the most reliable for getting a very clean break,” explains graduate student Crystal Owens.
CNN reporter Madeline Holcombe spotlights a new study by MIT researchers exploring why the cream on Oreo cookies always sticks to one side when twisted open. Graduate student Crystal Owens explains that she hopes the research will inspire people "to investigate other puzzles in the kitchen in scientific ways. The best scientific research, even at MIT, is driven by curiosity to understand the world around us, when someone sees something weird or unknown and takes the time to think 'I wonder why that happens like that?'"
Graduate student Crystal Owens speaks with Popular Science reporter Philip Kiefer about her work exploring why the cream filling of an Oreo cookie always sticks to one side. “It turns out there’s not really a trick to it,” Owens says. “Everything you try to do will get mostly a clean break.”
Graduate student Crystal Owens and her colleagues tested the possibility of separating the two wafers of an Oreo in a way that evenly splits the cream filling using a rheometer, an instrument that measures torque and viscosity of various substances, reports Becky Ferreira for Vice. “After twisting Oreos apart with the instruments, the team visually inspected the ratio of creme on each wafer and logged the findings. A number of variations on the experiment were also introduced, such as dipping the cookies in milk, changing the rotation rate of the rheometer, and testing different Oreo flavors and filling quantities,” writes Ferreira.
A team of researchers from MIT and the National Renewable Energy Laboratory successfully reached a 30% jump in thermophotovoltaic (TPV) efficiency, reports Robert F. Service for Science. “[TPV] is a semiconductor structure that concerts photons emitted from a heat source to electricity, just as a solar cell transforms sunlight into power,” explains Service.
Using cellulose nanocrystals found in trees, MIT researchers have developed a new material that is both tough and strong, reports Kathryn Hulick for Science News for Students. Abhinav Rao PhD ’18 explains that he was inspired to create the material “by looking at what nature has to teach us.”
Researchers from MIT have developed a new fabric that can hear and interpret what’s happening on and inside our bodies, reports Elana Spivack for Inverse. Beyond applications for physical health the researchers envision that the fabric could eventually be integrated with “spacecraft skin to listen to [accumulating] space dust, or embedded into buildings to detect cracks or strains,” explains Wei Yan, who helped develop the fabric as an MIT postdoc. “It can even be woven into a smart net to monitor fish in the ocean. It can also facilitate the communications between people who are hard of [hearing].”
Daily Beast reporter Miriam Fauzia writes that MIT researchers have developed a new way to create carbon fibers that are stronger and lighter than steel, using leftover waste from crude oil processing. “The new findings could usher in an age of heavy-duty cars that consume less fuel thanks to their decreased weight,” writes Fauzia.
Hill reporters Saul Elbein and Sharon Udasin spotlight how MIT researchers have developed a way to make lightweight fibers for possible use in the bodies of cars out of the waste material from the refining of petroleum. “The ‘heavy, gloppy’ leftovers from the petroleum refining process could become a key ingredient in making electric vehicles lighter, less expensive and more efficient,” they write.
Prof. Yoel Fink speaks with WHDH about his team’s work developing an acoustic fabric that can listen to and record sound, a development inspired by the human ear. "The fabric can be inserted into clothes to monitor heart rate and respiration. It can even help with monitoring unborn babies during pregnancy."
Bloomberg News spotlights how MIT researchers have developed a new material that works like a microphone, converting sounds into vibrations and then electrical signals. “The development means the possibility of clothes that act as hearing aids, clothes that answer phone calls, and garments that track heart and breathing rates,” writes Bloomberg News.
Researchers from MIT and the Rhode Island School of Design have developed a wearable fabric microphone that can detect and transmit soundwaves and convert them into electrical signals, reports Shi En Kim for Popular Science. “Computers are going to really become fabrics," says Prof. Yoel Fink. "We’re getting very close.”
MIT researchers have created a flexible fiber that can generate electrical impulses that are conveyed to the brain as sound, reports Miriam Fauzia for The Daily Beast. “The researchers see endless possibilities for their smart fabric,” writes Fauzia. “The obvious application is in improving hearing aids, which Fink said have trouble discerning the direction of sound, particularly in noisy environments. But the fabric could also help engineers design wearable fabrics that can measure vital signs, monitor space dust in new kinds of spacecraft, and listen for signs of deterioration in buildings like emerging cracks and strains.”
Prof. Yet-Ming Chiang and his colleagues are developing a new, inexpensive iron-air battery technology that could provide multi-day storage for renewable energy by 2024 through their startup Form Energy, reports Anuradha Varanasi for Popular Science. Chiang explains that “the battery can deliver clean electricity for 100 hours at a price of only $20 kilowatts per hour – a bargain compared to lithium-ion batteries, which cost up to $200/kWh,” writes Varanasi.
WBUR reporters Bruce Gellerman and David Greene spotlight Form Energy, a startup co-founded by MIT scientists with the mission to find a low-cost way to transform the global electric system. The startup “had a eureka moment when they thought about harnessing the rusting process to power batteries,” write Gellerman and Greene.
