Ariel Aberg-Riger is the author of America Redux: Visual Stories from Our Dynamic History.

The reason you are reading this letter from me today is that I was bored 30 years ago. I was bored and curious about the world and so I wound up spending a lot of time in the university computer lab, screwing around on Usenet and the early World Wide Web, looking for interesting things...

It all began with a simple origami model. As an undergrad at Harvard, Danna Freedman went to a professor's office hours for her general chemistry class and came across an elegant paper model that depicted the fullerene molecule. The intricately folded representation of chemical bonds and atomic arrangements sparked her interest, igniting a profound curiosity...

After decades of working as a biologist at a Southern school with a Division1 football team, coming to MIT was a bit of a culture shock-in the best possible way. I've heard from MIT alumni all about late-night psetting, when to catch MITHenge, and the best way to celebrate Pi Day (with pie, of course)....

Tiny flying robots could perform such useful tasks as pollinating crops inside multilevel warehouses, boosting yields while mitigating some of agriculture's harmful impacts on the environment. The latest robo-bug from an MIT lab, inspired by the anatomy of the bee, comes closer to matching nature's performance than ever before. Led by Kevin Chen, an associate...

Scientists have known for decades that certain neurons in the hippocampus are dedicated to remembering specific locations where an animal has been. More useful, though, is remembering where places are relative to each other, and it hasn't been clear how those mental maps are formed. A study by MIT neuroscientist Matthew Wilson and colleagues sheds...

In 2018 astronomers at MIT and elsewhere observed previously unseen behavior from a black hole known as 1ES 1927+654, which is about as massive as a million suns and sits in a galaxy 270 million light-years away. Its corona-a cloud of whirling, white-hot plasma-suddenly disappeared before reassembling months later. Now members of the team have...

One costly and time-consuming step in constructing a concrete building is creating the formwork," the wooden mold into which the concrete is poured. Now MIT researchers have developed a way to replace the wood with lightly treated mud. What we've demonstrated is that we can essentially take the ground we're standing on, or waste soil...

Soon after MIT's 18th president, Sally Kornbluth, was inaugurated in May 2023, she made it a priority to expand her early on-campus listening tour to alumni living and working around the world. She wanted to learn more about their priorities and their connections with MIT, while also engaging them in her expansive vision for its...

A new type of glue developed by researchers from MIT and Germany combines sticky polymers inspired by the mussel with the germ-fighting properties of another natural material: mucus. To stick to a rock or a ship, mussels secrete a fluid full of proteins connected by chemical cross-links. As it happens, similar cross-linking features are found...

Artificial Intelligence (AI) is emerging in everyday use cases, thanks to advances in foundational models, more powerful chip technology, and abundant data. To become truly embedded and seamless, AI computation must now be distributed-and much of it will take place on device and at the edge. To support this evolution, computation for running AI workloads...

My mind is still sharp and my hands work just fine, so I have no interest in getting help from AI to draw or write stories," says Lee Hyun-se, a legendary South Korean cartoonist best known for his seminal series A Daunting Team, a 1983 manhwa about the coming-of-age of heroic underdog baseball players. Still,...

Architecture often assumes a binary between built projects and theoretical ones. What physics allows in actual buildings, after all, is vastly different from what architects can imagine and design (often referred to as paper architecture"). That imagination has long been supported and enabled by design technology, but the latest advancements in artificial intelligence have prompted...

In satellite images, the 20-odd coral atolls of the Maldives look something like skeletal remains or chalk lines at a crime scene. But these landforms, which circle the peaks of a mountain range that has vanished under the Indian Ocean, are far from inert. They're the products of living processes-places where coral has grown toward...

This year has been rough for climate technology: Companies have canceled, downsized, or shut down at least 16 large-scale projects worth $8 billion in total in the first quarter of 2025, according to a new report.

When cofounder Jason Goodman opened Bathhouse's first location in Williamsburg...

Americans don't agree on much these days. Yet even at a time when consensus reality seems to be on the verge of collapse, there remains at least one quintessentially modern value we can all still get behind: creativity. We teach it, measure it, envy it, cultivate it, and endlessly worry about its death. And why...

The quest for long, healthy life-and even immortality-is probably almost as old as humans are, but it's never been hotter than it is right now. Today my newsfeed is full of claims about diets, exercise routines, and supplements that will help me live longer. A lot of it is marketing fluff, of course. It should...
