Graduate student Kartik Chandra writes for Inside Higher Education about how many of this year’s college graduates are feeling anxiety about new AI technologies. “We scientists are still debating the details of how AI is and is not humanlike in its use of language,” writes Chandra. “But let’s not forget the big picture: unlike AI, you speak because you have something to say.”
Researchers from MIT have found that, as a result of the Covid-19 pandemic, people are less likely to explore economically different parts of their home cities, reports Immanual John Milton for Bloomberg. “Fewer people are visiting attractions like museums, restaurants or parks that are outside their immediate mobility radius, and they’re spending less time among residents at different socioeconomic levels,” writes Milton.
Using the James Webb Space Telescope (JWST), postdoc Rohan Naidu and his colleagues will be using a giant cluster of galaxies to “gravitationally magnify the light of some smaller objects up to 750 million years after the big bang,” reports Jonathan O’Callaghan for Scientific American. “The goal is to look for clumps of primordial gas, which could contain clusters of Population III stars—the first stellar generation thought to have lit up the universe,” writes O’Callaghan.
Commonwealth Fusion Systems, MIT’s Plasma Science and Fusion Center and others are working to build SPARC, a prototype device that aims to extract net energy from plasma and generate fusion power, reports Philip Ball for Scientific American. “SPARC will be a midsize tokamak in which the plasma is tightly confined by very intense magnetic fields produced by new high-temperature superconducting magnets developed at MIT and unveiled in 2021.”
A study conducted by graduate student Aspen Hopkins and colleagues trained a version of a GPT neural network on the board game Othello “by feeding in long sequences of move in text form”, reports George Musser for Scientific American. “Their model became a nearly perfect player,” writes Musser.
Wired reporter Caitlin Harrington writes that a study by researchers from MIT and Stanford highlights the impact of generative AI tools on workers and raises a “provocative new question: Should the top workers whose chats trained the bot be compensated?”
Researchers at MIT are developing a new way to use electric thrusters, reports Freethink. “Electric propulsion actually has the benefit of maximizing the amount of room that you have on a spacecraft so you can use it for this useful payload as opposed to just propellant,” says Prof. Paulo Lozano.
Boston Globe reporter Robert Weisman spotlights Integrated Biosciences, a startup co-founded by MIT researchers that is using artificial intelligence to identify anti-aging drug candidates. “We’re trying to go after aging and aging-associated disorders,” says postdoc Felix Wong. “We all know loved ones who have suffered from some of these conditions.”
Researchers from MIT and elsewhere have tested the impact of generative AI among 5,000 customer service agents within a Fortune 500 software company, reports Jo Constantz for Bloomberg. “The company’s lowest-skilled workers became 35% faster with the tool,” explains Constantz. “The researchers think this was because the AI essentially transferred top performers’ knowledge to less-experienced colleagues through the automatically-generated recommended responses.”
Prof. Danielle Li, graduate student Lindsey Raymond and Stanford University Prof. Erik Brynjolfsson released an “empirical study of the real-world economic effects of new AI systems,” reports Greg Rosalsky for NPR. The researchers found “AI caused a group of workers to become much more productive.” Rosalsky adds that the study also “shines a spotlight on just how powerful AI is, how disruptive it might be, and suggests that this new, astonishing technology could have economic effects that change the shape of income inequality going forward.”
Boston Globe reporter Yvonne Abraham spotlights Postdoctoral Fellow Lydia Harrington and Boston University Postdoctoral Associate Chloe Bordewich and their work examining the history of Boston’s former Little Syria neighborhood. “It’s important that Bostonians think about this as part of their history,” says Bordewich. “But we also wanted to contribute something so that recent Syrian arrivals can engage and see part of their history, too.”
Quanta Magazine reporter Jordana Cepelewicz spotlights graduate students Ashwin Sah and Mehtaab Sawhney for their work proving the existence of special objects called “subspace designs.” Sah and Sawhney have “proved the existence of objects whose existence is not at all obvious,” said Prof. David Conlon of the California Institute of Technology. “They’re producing high-quality research at a rate where I can’t even blink.”
WCVB spotlights postdoctoral associate Matt McDonald and his efforts to prepare for the 2023 Boston Marathon. McDonald, who finished fourth in the American pack at last year’s marathon and first among New Englanders, says “the crowds are unbelievable. And knowing that you’ve done it at that point, makes it just incredibly emotional.”
Wired reporter Will Knight spotlights a new working paper by graduate students Shakked Noy and Whitney Zhang examining the impact of providing office workers access to ChatGPT for use in a series of office tasks. The researchers found “people with access to the chatbot were able to complete the assigned tasks in 17 minutes, compared to an average 27 minutes for those without the bot, and that the quality of their work improved significantly,” writes Knight.
Bloomberg reporters Alex Tanzi and Mackenzie Hawkins spotlight a paper by graduate student Evan J. Soltas and his colleague Gopi Shah Goda discussing Covid-19’s impact on the labor market. The researchers “found that workers who miss a full week because of COVID are about 7 percentage points less likely to be employed a year later,” writes Tanzi and Hawkins.
