Researchers at MIT’s Senseable City Lab have found that academics missed out on forming new connections during Covid-19 lockdowns, hindering academic collaboration, reports Tom Williams for Times Higher Education. “Colleagues associated more with previous collaborators, which could create closed loops of communication, rather than with new potential collaborators, which enables the critical exchange that stimulates research and innovation,” says postdoctoral researcher Daniel Carmody.

Researchers at MIT and other institutions have developed an artificial intelligence tool that can analyze changes in nighttime breathing to detect and track the progression of Parkinson’s disease, reports Casey Ross for STAT. “The AI was able to accurately flag Parkinson’s using one night of breathing data collected from a belt worn around the abdomen or from a passive monitoring system that tracks breathing using a low-power radio signal,” writes Ross.

Loh Down on Science host Sandra Tsing Loh spotlights Prof. Cathy Wu and graduate student Vindula Jayawardana and their work developing a new method for self-driving vehicles that would help minimize idling at red lights. “In their method, self-driving can be taught to minimize stops at red lights. To make this work, traffic lights and self-driving cars would have sensors. This would let them check in with each other on their surroundings,” says Loh.

MIT scientists have discovered a new method to maximize wind farm output, reports Gwen Egan for Boston.com. “While there are pros and cons to this strategy, it’s possible that it could allow for smaller wind farms that take up less land to produce more energy,” says Prof. Michael Howland. “It’s critically important we do this now, as we embark on building much more offshore wind. We need to ensure that our future wind farms maximize efficiency to increase the pace of decarbonization.”

Researchers from MIT, Harvard University, and the Georgia Institute of Technology have examined the impact of tech startups working in close proximity, reports Cheryl Winokur Munk for The Wall Street Journal. The researchers found that “'knowledge spillovers' were greatest between dissimilar startups that worked within 20 meters (22 yards) of each other,” writes Munk. “Working in such close range allowed for socialization, which in turn led to idea sharing about the types of technology the startups were using as part of their overall tech infrastructure.”

MIT scientists have found that changing the angle of turbine blades on wind farms could increase energy output, reports David Abel for The Boston Globe. “Given the scale of wind deployment needed to achieve state and federal climate goals, we need optimal wind farm performance to ensure efficient, rapid decarbonization,” says Prof. Michael Howland. “Our method resulted in significant energy gains over standard industry operations, and, importantly, it can be instituted with minimal cost.”

Prof. Jörn Dunkel and his colleagues have proposed the use of nematic liquid crystals as the potential future basic building blocks for computers, reports Karmela Padavic-Callaghan for New Scientist. According to Dunkel, “because the liquid crystal computer wouldn’t use only 0s and 1s, some of its computations would be analogous to how quantum computers work, as they can simultaneously process more information than conventional computers,” writes Padavic-Callaghan.

Sharing automated vehicle data with the public can fundamentally change the way regulators, police departments, insurance companies and other organization understand the risks of drive-assistance systems, report Cade Metz and Ella Koeze for The New York Times. “This can help separate crashes related to technology from crashes related to driver error,” says research engineer Bryan Reimer.

Postdoctoral fellow Joshua Schwartz and Texas A&M University Prof. Matthew Fuhrmann write for The Washington Post about their research to analyze whether armed drone operations reduce terrorism or make countries more vulnerable to it. “Armed drones may raise ethical concerns but appear to be an effective counterterrorism tool,” argue Schwartz and Fuhrmann. “However, the decision of when, how or even whether to employ armed drones remains a difficult one.”

Researcher Hojun Li and his team have developed a new Covid-19 at-home test that looks “specifically at the levels of neutralizing antibodies and either give a precise level or a ‘low,’ ‘medium,’ ‘high’ reading, providing more actionable information,” reports Karen Weintraub for USA Today.

Researchers at MIT believe they have found a new semiconductor that's better than silicon, which could open the doors to potentially faster and smaller computer chips in the future, reports Rachel Cheung for Vice. “Cubic boron arsenide has significantly higher mobility to both electronics and their positively charged counterparts than silicon, the ubiquitous semiconductor used in electronics and computers,” explains Cheung.

Professor Eric Alm speaks with Claire Ainsworth at New Scientist about studying wastewater to better understand the health, wealth and environment of various communities. “It’s not about going in and taking a measurement,” said Alm. “It’s about developing a platform that can help you reach insights about what’s going on.”

Researchers at MIT and other institutions proved “that cubic boron arsenide performs better than silicon at conducting heat and electricity,” reports Nicholas Gordon for Fortune. “The new material may help designers overcome the natural limits of current models to make better, faster, and smaller chips,” writes Gordon.

Prof. Mircea Dincă and Grama Sorin co-founded Transaera, a company dedicated to designing air conditioners that require significantly less energy, reports Scott Kirsner for The Boston Globe. “Grama and Dincă cofounded Transaera in 2018 and supported their early work with about $2 million in state and federal grants, from agencies that included the Massachusetts Clean Energy Center,” writes Kirsner.

Joseph Coughlin, Director of the MIT AgeLab, writes for Forbes about Serena William’s recent retirement announcement and the evolving concept of retirement. “Tennis star Serena Williams announced her ‘retirement’ from tennis this week while challenging the very idea of retirement,” writes Coughlin. “Williams is not alone. Many people, far older than her 41 years, are declaring retirement a dated term best left to past generations and another era.”
