The large factories that have historically manufactured all of the world’s hydrogen peroxide have new, microscopic competitors: altered protein molecules called enzymes. Certain enzymes, which quicken the pace of chemical reactions, have long been known to work with hydrogen peroxide in various biological systems. But translating that knowledge into a biological-based way to create hydrogen […] More
Cities have wealth disparities: Picture fancy downtown condos and trendy shopping areas in contrast to, say, streets with rundown housing and boarded-up shops. Cities also have health disparities: People who live in well-off parts of metro areas are less exposed to many of the pollutants, risks, and stresses that lead to long-term health problems. The […] More
MIT biologists have discovered an unexpected effect of a ketogenic, or fat-rich, diet: They showed that high levels of ketone bodies, molecules produced by the breakdown of fat, help the intestine to maintain a large pool of adult stem cells, which are crucial for keeping the intestinal lining healthy. The researchers also found that intestinal […] More
To investigate the vastly unexplored oceans covering most our planet, researchers aim to build a submerged network of interconnected sensors that send data to the surface — an underwater “internet of things.” But how to supply constant power to scores of sensors designed to stay for long durations in the ocean’s deep? MIT researchers have […] More
At the 2019 MIT Commencement address, Michael Bloomberg highlighted the climate crisis as “the challenge of our time.” Climate change is expected to worsen drought and cause Boston, Massachusetts, sea level to rise by 1.5 feet by 2050. While numerous MIT students and researchers are working to ensure access to clean and sustainable sources of […] More
Marcus “Marc” G. Karel PhD ’60, professor emeritus of chemical engineering, died on July 25 at age 91. A member of the MIT community since 1951, Karel inspired a generation of food scientists and engineers through his work in food technology and controlled release of active ingredients in food and pharmaceuticals. Karel was born in […] More
The Abdul Latif Jameel Water and Food Systems Lab (J-WAFS) has announced the selection of their third cohort of graduate fellows. Two students will each receive one-semester graduate fellowships as part of J-WAFS’ Rasikbhai L. Meswani Fellowship for Water Solutions and J-WAFS Graduate Student Fellowship Programs. An additional student was awarded “honorable mention.” J-WAFS will also support […] More
When a raindrop falls through a thundercloud, it is subject to strong electric fields that pull and tug on the droplet, like a soap bubble in the wind. If the electric field is strong enough, it can cause the droplet to burst apart, creating a fine, electrified mist. Scientists began taking notice of how droplets […] More
