Everything is a Brand

It’s a weird, weird quantum world

March 10, 2023

In 1994, as Professor Peter Shor PhD ’85 tells it, internal seminars at AT&T Bell Labs were lively affairs. The audience of physicists was an active and inquisitive bunch, often pelting speakers with questions throughout their talks. Shor, who worked at Bell Labs at the time, remembers several occasions when a speaker couldn’t get past their third slide, as they attempted to address a rapid line of questioning before their time was up. That year, when Shor took his...

Engaging enterprises with the climate crisis

March 10, 2023

Almost every large corporation is committed to achieving net zero carbon emissions by 2050 but lacks a roadmap to get there, says John Sterman, professor of management at MIT’s Sloan School of Management, co-director of the MIT Sloan Sustainability Initiative, and leader of its Climate Pathways Project. Sterman and colleagues offer a suite of well-honed strategies to smooth this journey, including a free global climate policy simulator called En-ROADS deployed in workshops that have educated more than 230,000 people,...

Shrinky Dinks, nail polish, and smelly bacteria

March 10, 2023

In a lab on the fourth floor of MIT’s Building 56, a group of Massachusetts high school students gathered around a device that measures conductivity. Vincent Nguyen, 15, from Saugus, thought of the times the material on their sample electrode flaked off the moment they took it out of the oven. Or how the electrode would fold weirdly onto itself. The big fails were kind of funny, but discouraging. The students had worked for a month, experimenting with different...

Celebrating a decade of a more sustainable...

March 10, 2023

When MIT’s Office of Sustainability (MITOS) first launched in 2013, it was charged with integrating sustainability across all levels of campus by engaging the collective brainpower of students, staff, faculty, alumni, and partners. At the eighth annual Sustainability Connect, MITOS’s signature event, held nearly a decade later, the room was filled with MIT community members representing 67 different departments, labs, and centers — demonstrating the breadth of engagement across MIT. Held on Feb. 14 and hosting more than 100...

How to assemble a complete jaw

March 10, 2023

The skeleton, tendons, and glands of a functional jaw all derive from the same population of stem cells, which arise from a cell population known as neural crest. To discover how these neural crest-derived cells know to make the right type of cell in the right location, researchers focused on a particular gene, Nr5a2, that was active in a region of the face that makes tendons and glands, but not skeleton. To understand the role of Nr5a2, the scientists...

Jewel beetles evolve to see new colors...

March 10, 2023

Jewel beetles are striking insects, easily recognized by their vivid colors and metallic sheen. New research investigated the complex evolutionary history of jewel beetles’ vision.

MIT professor to Congress: “We are at...

March 10, 2023

Government should not “abdicate” its responsibilities and leave the future path of artificial intelligence solely to Big Tech, Aleksander Mądry, the Cadence Design Systems Professor of Computing at MIT and director of the MIT Center for Deployable Machine Learning, told a Congressional panel on Wednesday. Rather, Mądry said, government should be asking questions about the purpose and explainability of the algorithms corporations are using, as a precursor to regulation, which he described as “an important tool” in ensuring that...

2023 MacVicar Faculty Fellows named

March 10, 2023

The Office of the Vice Chancellor and the Registrar’s Office have announced this year’s Margaret MacVicar Faculty Fellows: professor of brain and cognitive sciences John Gabrieli, associate professor of literature Marah Gubar, professor of biology Adam C. Martin, and associate professor of architecture Lawrence “Larry” Sass. For more than 30 years, the MacVicar Faculty Fellows Program has recognized exemplary and sustained contributions to undergraduate education at MIT. The program is named in honor of Margaret MacVicar, the first dean...

Matthew Kearney: Bringing AI and philosophy into...

March 10, 2023

Matthew Kearney was drawn to MIT by the culture of its cross-country team. Growing up in Austin, Texas, he loved spending time outdoors and playing soccer, but by high school running had become his primary sport. While looking at colleges, he wanted to find a place with both strong academics and a strong team community. After an official visit with the cross-country team, he knew MIT was the place for him. “It’s been truly a defining part of my...

Standard model of electroporation refuted

March 9, 2023

Strong electric fields can be used to create pores in biomembranes. The method is known as electroporation. Inducing such defects in membranes in a targeted manner is an important technique in medicine and biotechnology, but also in the treatment of foodstuffs.

Pilot, engineer, neuroscientist, bridge-builder

March 9, 2023

At first glance, aerospace engineering and brain and cognitive sciences may seem like an unlikely match for a double-major. But for Elissa Gibson ’22, the common thread connecting the two inherently different disciplines is clear: the human factor, by way of aviation. A lifelong love of airplanes helped Gibson discover the MIT Introduction to Technology, Engineering, and Science, or MITES (formerly known as the Office of Engineering Outreach Programs), which helped carve a direct pathway to MIT. There, the...

Titanic robots make farming more sustainable

March 9, 2023

There’s a lot riding on farmers’ ability to fight weeds, which can strangle crops and destroy yields. To protect crops, farmers have two options: They can spray herbicides that pollute the environment and harm human health, or they can hire more workers. Unfortunately, both choices are becoming less tenable. Herbicide resistance is a growing problem in crops around the world, while widespread labor shortages have hit the agricultural sector particularly hard. Now the startup FarmWise, co-founded by Sebastien Boyer...

Creating a versatile vaccine to take on...

March 9, 2023

One of the 12 labors of Hercules, according to ancient lore, was to destroy a nine-headed monster called the Hydra. The challenge was that when Hercules used his sword to chop off one of the monster’s heads, two would grow back in its place. He therefore needed an additional weapon, a torch, to vanquish his foe. There are parallels between this legend and our three-years-and-counting battle with SARS-Cov-2, the virus that causes Covid-19. Every time scientists have thought they’d...

New biosensor reveals activity of elusive metal...

March 9, 2023

A new biosensor offers scientists the first dynamic glimpses of manganese, an elusive metal ion that is essential for life.

What 'Chornobyl dogs' can tell us about...

March 9, 2023

In the first step toward understanding how dogs — and perhaps humans — might adapt to intense environmental pressures such as exposure to radiation, heavy metals, or toxic chemicals, researchers found that two groups of dogs living within the Chernobyl Exclusion Zone showed significant genetic differences between them. The results indicate that these are two distinct populations that rarely interbreed. While earlier studies focused on the effects of the Chernobyl Nuclear Power Plant disaster on various species of wildlife,...
