Researchers at MIT have created “a resin that turns into two different kinds of solids, depending on the type of light that shines on it,” a development that could “significantly speed up the 3D-printing process,” reports Andrew Corselli for Tech Briefs. Graduate student Nicholas Diaco explains that this new method “allows us in a single 3D print, to create structures that either dissolve or don't dissolve away. That lets us automate the most difficult and most expensive step of 3D printing, which is removing support materials after the printing is done.”

Writing for The New York Times, Prof. David Autor and Prof. Gordon Hanson of Harvard explore how China is “aggressively contesting the innovative sectors where the United States has long been the unquestioned leader." To avoid a second China Shock, they emphasize that the United States “must nourish industries that have high potential for innovation, funded by joint investments by the private and public sectors.” 

In his new book, “The Comedy of Computation: Or, How I Learned to Stop Worrying and Love Obsolescence,” Prof. Benjamin Mangrum explores how comedy can be a useful tool in a world “increasingly shaped by algorithms, automation, and artificial intelligence,” reports Ed Publica. “As we move deeper into an era of smart machines, digital identities, and algorithmic decision-making, Mangrum’s book reminds us that a well-placed joke might still be one of our most human responses,” they write.

In an opinion piece for Bloomberg, Gautam Mukunda PhD '10 highlights the importance of federally funded scientific research. “Today, the federal government’s best investment is scientific research,” writes Mukunda. “The Federal Reserve estimates that support for science has a 150% to 300% return. Few investors have a track record as good.” 

Prof. David Autor speaks with ABC News reporter Max Zahn about how AI will affect the job market. "We're not good at predicting what the new work will be; we're good at predicting how current work will change," says Autor.

MIT researchers have developed a bionic knee that “allows amputees to walk faster, climb stairs more easily, and adroitly avoid obstacles,” reports Dennis Thompson for HealthDay. “The new prothesis is directly integrated with the person’s muscle and bone tissue, enabling greater stability and providing more control over its movement,” Thompson explains. 

Researchers at MIT have developed a bionic knee that can “integrate with a patient’s bones and nervous system, allowing users to control the prosthesis with their mind,” reports Angela Mathew for The Boston Globe. “In conventional prosthesis, there’s an energy exchange, but there’s not much of an information exchange with the brain,” explains Prof. Hugh Herr. “Because the prosthesis is so intimately connected to the skeleton, if you just tap the toe in a really modest way, the person can feel it exquisitely.”  

Prof. Giovanni Traverso speaks with WCVB about his research developing an ingestible robotic capsule capable of delivering an injection directly within the stomach. “Fifty percent of the population don’t take medication as prescribed. That’s incredible,” says Traverso. “So, if we can make a little dent, or hopefully a bigger dent, I think we can help a lot of folks out there.”  

Researchers at MIT have designed an implantable device that can be used to administer a dose of glucagon to protect Type 1 diabetics from hypoglycemia, reports Amir Khollam. “The device, about the size of a quarter, sits under the skin and releases a dose of glucagon when blood sugar levels dip too low,” explains Khollam. “It can be activated manually or triggered wirelessly by a sensor.” 

Prof. Simon Johnson speaks with Planet Money host Robert Smith about the role institutions play in prosperity gaps in different countries. “I think democracy is absolutely essential for shared prosperity, because if power isn't widely shared across society, in any kind of authoritarian system, you're going to have a situation where, you might have a good ruler or a pro-growth ruler for a while,” says Johnson. “But then they're going to get cranky. They're going to die and pass it on to somebody else who's really not good for growth. So authoritarian rulers are highly unreliable in terms of sustained prosperity." 

Researchers at MIT have designed a new chip component that can “expand the reach of the Internet of Things into 5G,” reports Margo Anderson for IEEE Spectrum. “The discovery represents a broader push for 5G-based IoT tech—using the telecom standard’s low latency, energy efficiency, and capacity for massive device connectivity,” explains Anderson. “The new research also signals an important step toward applications that include smaller, low-power health monitors, smart cameras, and industrial sensors, for instance.” 

A study by MIT researchers has found “our behavior is often more predictable than we think,” reports Diane Hamilton for Forbes. “This research focused on how people pay attention in complex situations,” explains Hamilton. “The AI model learned what people remembered and what they ignored. It identified patterns in memory and focus.” 

Prof. Danielle Li speaks with New York Times reporter Noam Scheiber about the various impacts of AI in the workplace on employees. “That state of the world is not good for experienced workers,” says Li. “You’re being paid for the rarity of your skill, and what happens is that A.I. allows the skill to live outside of people.”

Forbes reporter Eric Wood spotlights various studies by MIT researchers exploring the impact of ChatGPT use on behavior and the brain. “As stated, the impact of AI assistants is likely dependent on the users, but since AI assistants are becoming normative, it’s time for counseling centers to assess for maladaptive uses of AI, while also promoting the possible benefits,” explains Wood.

A new research paper by Prof. David Autor and Principal Research Scientist Neil Thompson explores the forthcoming impact of AI on jobs, reports Tim Harford for Financial Times. “[W]hile there are few certainties, Autor and Thompson’s framework does suggest a clarifying question: does AI look like it is going to do the most highly skilled part of your job or the low-skill rump that you’ve not been able to get rid of?,” writes Harford. “The answer to that question may help to predict whether your job is about to get more fun or more annoying — and whether your salary is likely to rise, or fall as your expert work is devalued like the expert work of the Luddites.”
