Prof. Desiree Plata speaks with AccuWeather senior on-air meteorologist Geoff Cornish about her research in using zeolite clay to control and remove methane emissions from the air.  “So, the really interesting thing about zeolite is it has these cool pore spaces so when you drop copper into those pore spaces it can grab onto a methane molecule and attach an oxygen atom to it and that helps convert that methane into carbon dioxide which is a much less potent greenhouse gas and so the net benefit to the climate can be quite dramatic,” explains Plata.

Katie Spies ’14, founder and CEO of Maev (a company that produces human-grade, raw dog food brand), speaks with Fortune editor Rachel King about what inspired her to start Maev, the company’s development process, and where Spies sees the company expanding in the future. “Among other exciting expansion initiatives, we’re really looking forward to expanding our product portfolio; our goal is to be a trust brand for dog essentials, especially product categories that are currently lacking in healthy, well-made options,” says Spies.

Prof. Lydia Bourouiba speaks with BBC CrowdSource presenter Marnie Chesterton about her work in understanding how bodily fluids such as snot and spittle spread after leaving the body using high speed cameras.  “What is very clear is that we emit… droplets of a continuum of sizes but they are not coming out alone,” explains Bourouiba. “They are coming out with an air that is in our lungs, that is hot and moist and turbulent, which changes the physical dynamics of the emission and how the drops will evolve.”

TechCrunch reporter Christine Hall spotlights Anwar Ghauche MS ’10, CEO of Constrafor - a construction procurement platform that streamlines information, payment, and documentation between general contractors and subcontractors. “Subcontractors get hired on the project, and when they finish their first month of work, submit an invoice and then wait an average of 45 to 60 days — even up to 80 days — to get paid,” says Ghauche.  “Meanwhile, they are buying equipment and borrowing money to be able to do all of this work. You’re not borrowing at a cheap rate, either, because most banks barely touch them.”

TechCrunch reporters Kyle Wiggers and Devin Coldewey spotlight how MIT researchers developed a new technique for simulating an overall system of independent agents: self-driving cars. “The idea is that if you have a good amount of cars on the road, you can have them work together not just to avoid collisions but to prevent idling and unnecessary stops at lights,” write Wiggers and Coldewey.

MIT researchers have found that zeolite, a material used to soak up odors in kitty litter, can be used to grab methane out of the air, reports Angely Mercado for Gizmodo.  “Zeolite has tiny pores that act like sponge, and the clay is pretty multifunctional: It can help improve water retention in soil, and it’s found in natural kitty litter,” explains Mercado.

Prof. Markus Buehler and his lab have been studying the sonification of molecules by capturing their vibrations and using a computer program to turn the mini vibrations into audible sounds, reports Sofia Quaglia for Smithsonian Magazine. “Buehler believes that since creativity has led to such complex varieties of music over the years—from classical to techno—maybe this creativity could be translated from an immaterial, pleasant experience, to scientific knowledge to make something physical,” writes Quaglia.

Wall Street Journal reporter Ryan Dezember visited Prof. Desiree Plata’s lab to learn more about her group’s work developing a new tool to help address climate change. Plata and her colleagues “soaked an odor-eating clay used in cat boxes in a copper solution to create a compound that they say snatches methane from passing air and turns it into carbon dioxide, a much less harmful greenhouse gas.” The new technique has the “potential to greatly reduce the amount of methane in the atmosphere and slow warming temperatures on the planet.”

MIT announced five projects "targeting the world's toughest climate riddles" that were selected following a rigorous two-year competition, reports Benjamin Kail for Boston Business Journal. “Climate Grand Challenges represents a whole-of-MIT drive to develop game-changing advances to confront the escalating climate crisis, in time to make a difference,” says President L. Rafael Reif.

According to Prof. Yossi Sheffi, increasing customer demand is the driving force behind the supply chain bottlenecks impacting the global delivery network. “The smoking gun for consumer demand as the main culprit is that bottlenecks didn’t emerge as a significant hurdle until spring of 2021, says Sheffi…That was after the federal government has juiced spending by sending three rounds of stimulus checks to most households,” writes Paul Davidson for USA Today.

With the announcement of the new MIT Morningside Academy for Design, MIT is looking to create “a hub of resources for the next generation of designers, integrating areas of study such as engineering and architecture in the process,” reports Dana Gerber for The Boston Globe. “This is really going to give us a platform to connect with the world around problems that communities are facing,” explained Prof. John Ochsendorf, who will serve as the academy’s founding director.

MIT has announced the creation of a new multidisciplinary center, called Morningside Academy for Design, which is intended to serve as a “focal point for design research, education, and entrepreneurship,” reports Michael T. Nietzel for Forbes. 

MIT has announced the establishment of the MIT Morningside Academy for Design, reports Susan H. Greenberg for Inside Higher Ed. The new center “aims to foster collaboration and innovation across academic disciplines – including engineering, science, management, computing, architecture, urban planning and the arts – to address such pressing global issues as climate change, public health, transportation, and civic engagement,” writes Greenberg.

Provost Cynthia Barnhart PhD ’88 reflects on her time as chancellor and her new role at MIT with Jennifer Ai of The Tech. “I really do want to help members of our community thrive here at MIT, because if they thrive, MIT thrives,” says Barnhart. “That very much motivates how I think things must be.”

Wired reporter Gregory Barber spotlights Prof. Desirée Plata’s work developing a new process for removing methane emissions using zeolite. Plata’s team is currently working on converting their system to a filter that air can be pushed through. “Plata wants to install the filters in places where methane is concentrated, but there’s not enough of it to burn,” Barber explains.
