MIT researchers have successfully figured out how to trap tiny electrons in a three-dimensional crystal prison, reports Jess Thomson for Newsweek. The researchers hope that “the flat band properties of the electrons in these crystals will help them to explore new quantum states in three-dimensional materials,” Thomson explains, “and therefore develop technology like superconductors, supercomputing quantum bits, and ultraefficient power lines.”
Cognito Therapeutics, founded by Prof. Ed Boyden and Prof. Li Huei Tsai, has developed a “specialized headset that delivers 40Hz auditory and visual stimulation” to the brain, which could potentially slow down the cognitive decline and neurodegeneration in Alzheimer’s disease, reports William A. Haseltine for Forbes. Prof. Li-Huei Tsai “and her team speculated that if gamma wave activity is reduced in Alzheimer’s disease, perhaps, artificially stimulating the brain may enhance synchronized firing and restore cognition,” writes Haseltine.
Principal Research Scientist Andrew McAfee writes for Fast Company about the makings of a successful corporate culture. “I’ve come to believe that the most fundamental reason Silicon Valley companies are disrupting so many industries is that they’ve iterated and experimented their way into a corporate culture that supports high levels of agility, innovation, and execution simultaneously,” writes McAfee. “I call this culture the geek way. It’s based on four norms expected by those around you (and not just the bosses).”
Prof. Pierre Azoulay speaks with Wall Street Journal reporter Bob Fernandez about new research that highlights how immigrant workers, “account for nearly one-in-five of the top 1% wage earners in the U.S.” Azoulay notes that: “One reason that immigrants do better is that they locate in places that are growing fast and the earnings potential are high. They do not randomly locate around the United States.”
Writing for the Financial Times, Prof. Carlo Ratti explores the concept of the “15-minute city,” which is aimed at creating walkable neighborhoods. “The 15-minute city must be paired with investment in transport between neighborhoods,” writes Ratti, noting that investment is especially needed in public transportation to ensure that 15-minute cities do not contribute to greater segregation.
A study co-authored by research scientist Evan Fricke found that “extinctions and declines in habitat [of migratory birds] have dramatically reduced the long-distance dispersal of seeds,” reports Liam Drew for The Atlantic. “There have been really strong declines in long-distance seed dispersal as a result of the massive loss of big animals from the ecosystems,” says Fricke.
Prof. Kerry Emanuel speaks with Living on Earth host Jenni Doering about the future of extreme weather forecasting. “We have to do a much better job projecting long term risk, and how that's changing as the climate changes so that people can make intelligent decisions about where they're going to live, what they're going to build, and so on,” says Emanuel. “We need better models, we need better computers, so that we can resolve the atmosphere better, we need to make better measurements of the ocean below the surface, that's really tough to do.”
In a cartoon for The Boston Globe, Sage Stossel spotlights how during the Cambridge Science Festival researchers from the MIT AgeLab spoke about their work during a special presentation at the Cambridge Senior Center. As part of an effort to spur innovations aimed at improving the quality of life for people in their later years, AgeLab researchers have “pursued an array of projects, from researching safer, more automated driving systems to collaborating on ‘smart home’ innovations for facilitating aging in place to the development of interactive robo-pets.”
A new study co-authored by Prof. Roberto Fernandez examines the obstacles facing women seeking to advance their careers in tech, reports Sarah Shemkus for The Boston Globe. The researchers found “recruiters were more likely to reach out to men and had longer conversations with male candidates,” writes Shemkus. “And women needed more impressive resumes to make the cut for recruiter outreach.”
Los Angeles Times reporter Brian Merchant spotlights Joy Buolamwini PhD '22 and her new book, “Unmasking AI: My Mission to Protect What is Human in a World of Machines.” “Buolamwini’s book recounts her journey to become one of the nation’s preeminent scholars and critics of artificial intelligence — she recently advised President Biden before the release of his executive order on AI — and offers readers a compelling, digestible guide to some of the most pressing issues in the field,” writes Merchant.
Joy Buolamwini PhD '22 speaks with Brian Bergstein of The Boston Globe’s “Say More” podcast about her academic and professional career studying bias in AI. “As I learned more and also became familiar with the negative impacts of things like facial recognition technologies, it wasn’t just the call to say let’s make systems more accurate but a call to say let’s reexamine the ways in which we create AI in the first place and let’s reexamine our measures of progress because so far they have been misleading,” says Buolamwini
A study co-authored by Prof. Anna Stansbury finds that “as the share of graduates in the UK workforce has expanded over the past 25 years, the wage premium they command relative to non-graduates has fallen,” reports John Burn-Murdoch for Financial Times. “We can thus infer that in the aggregate, Britain’s supply of skilled workers is outstripping demand in the form of skilled jobs,” writes Burn-Murdoch.
Prof. Fiona Murray and her colleagues have found that female STEM PhD students are less likely than their male counterparts to receive mentorship from top inventor advisors, reports Women We Admire. The researchers “emphasize the importance of early intervention and encouragement for female PhD students aspiring to become inventors. Programs that actively support female professors in their patenting endeavors can indirectly lead to a surge in female inventor PhDs, thereby plugging the leaky pipeline.”
Science News reporter James Riordon writes that by employing a new technology called frequency-dependent squeezing, LIGO detectors should now be able to identify about 60 more mergers between massive objects like black holes and neutron stars than before the upgrade. Senior research scientist Lisa Barsotti, who oversaw the development of this new technology, notes that even next-generation gravitational wave detectors will be able to benefit from quantum squeezing. “The beauty is you can do both. You can push the limit of what is possible from the technology of laser power and mirror [design],” Barsotti explains, “and then do squeezing on top of that.”
MIT researchers have developed a new programmable, shape-changing smart fiber called FibeRobo that can change its structure in response to hot or cold temperatures, reports Andrew Paul for Popular Science. “FibeRobo is flexible and strong enough to use within traditional manufacturing methods like embroidery, weaving looms, and knitting machines,” writes Paul. “With an additional ability to combine with electrically conductive threads, a wearer could directly control their FibeRobo clothing or medical wearables like compression garments via wireless inputs from a controller or smartphone.”
