MIT researchers have created “Dribblebot,” a four-legged robot capable of playing soccer across varying terrain, reports Brian Heater for TechCrunch.

Researchers at MIT have created a four-legged robot capable of dribbling a soccer ball and running across a variety of terrains, reports Ross Cristantiello for Boston.com. “Researchers hope that they will be able to teach the robot how to lift a ball over a step in the future,” writes Cristantiello. “They will also explore how the technology behind DribbleBot can be applied to other robots, allowing machines to quickly transport a range of objects around outside using legs and arms.”

Prof. Marzyeh Ghassemi speaks with Scientific American reporter Sara Reardon about the impact of AI chatbots on medical care. “Ghassemi is particularly concerned that chatbots will perpetuate the racism, sexism and other types of prejudice that persist in medicine—and across the Internet,” writes Reardon. “Scrubbing racism from the Internet is impossible, but Ghassemi says developers may be able to do preemptive audits to see where a chatbot gives biased answers and tell it to stop or to identify common biases that pop up in its conversations with users.”

Principal Research Scientist Leo Anthony Celi co-authored a study that found “a lack of racial and gender diversity could be hindering the efforts of researchers working to improve the fairness of artificial intelligence (AI) tools in health care,” reports Carissa Wong for Nature.

Thousands of scientists and tech leaders have signed an open letter published by the Future of Life Institute, co-founded by Prof. Max Tegmark, “calling for a six-month ‘pause’ in further development of AI systems such as OpenAI’s ChatGPT and its more advanced version, GPT-4,” reports Hiawatha Bray for The Boston Globe. “We’re trying to pause development…to ensure we can get the upside from AI without unnecessary downside,” says Tegmark.

Prof. Carlo Ratti speaks with CNN reporter Sarah Engel about smart cities and the future of AI infrastructure. Ratti says the key to avoiding pitfalls is to keep citizens engaged: “They should be the ones to decide what kind of city they want to live in tomorrow.”

Researchers at the McGovern and Broad Institutes have developed a bacterial "nanosyringe" that can inject large proteins into specific cells in the body, which could lead to safer and more effective treatments for a variety of conditions, including cancer, reports Michael Le Page for New Scientist. “The fact that this can load a diversity of different payloads of different sizes makes it unique amongst protein delivery devices,” says graduate student Joseph Kreitz.

Ingrid Wickelgren at Scientific American highlights a new study from researchers at the McGovern and Broad Institutes, in which they used a bacterial ‘nanosyringe’ to inject large proteins into human cells. “The syringe technology also holds promise for treating cancer because it can be engineered to attach to receptors on certain cancer cells,” writes Wickelgren.     

Al Jazeera reporter Somesh Jha highlights the work of research associate Georgios Petropoulos, who is examining the ways in which artificial intelligence can impact jobs. “His work has shown that in past industrial revolutions too, the displacement of jobs might have dominated in the short run,” writes Jha, “but in the long term, when the markets adapt to the automation shock, increased productivity actually sets the stage for more employment opportunities.”

Prof. Aleksander Mądry’s testimony before a House subcommittee was highlighted by Politico fellow Mohar Chatterjee in a recent newsletter exploring how large tech companies are dominating how generative AI technologies are developed and utilized. During his testimony, Mądry emphasized that “very few players will be able to compete, given the highly specialized skills and enormous capital investments the building of such systems requires.”

Researchers at MIT have quantified the shift toward the artificial intelligence industry and how it has impacted academia, reports Madhumita Murgia for Financial Times. “The MIT research found that almost 70 percent of AI PhDs went to work for companies in 2020, compared to 21 per cent in 2004,” writes Murgia.

Using an artificial intelligence system, researchers at MIT and elsewhere have developed a new Covid-19 vaccine that could be effective against current and future strains, reports Gwen Egan for Boston.com. “The vaccine differs from others currently on the market due to the portion of the virus being targeted,” writes Egan.  

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.

Boston Globe reporter Hiawatha Bray writes that MIT researchers have used an AI system to identify a potential new Covid-19 vaccine that may be effective against both current and future variants of the virus. “The new vaccine targets a portion of the COVID virus that is much less prone to evolve,” writes Bray. “That could potentially make it effective against many different versions of the virus, eliminating the need for routine booster shots.”

MIT researchers have developed a new approach to vaccines that uses “a machine learning twist [that] could put an end to boosters and seasonal variant shots,” reports Devin Coldewey for TechCrunch.
