Researchers at MIT have discovered that pictures of food appear to stimulate strong reactions among specific sets of neurons in the human brain, a trait that could have evolved due to the importance of food for humans, reports Sascha Pare for The Guardian. “The researchers posit these neurons have gone undetected because they are spread across the other specialized cluster for faces, places, bodies and words, rather than concentrated in one region,” writes Pare.
Prof. Sara Seager and her team have organized three missions to Venus to search for signs of life in the clouds surrounding the planet, reports David Axe for the Daily Beast. Each mission “would fling a probe into the toxic planet’s acidic atmosphere and collect data on the presence, or absence, of something resembling life,” explains Axe.
Prof. Donald Sadoway and his colleagues have developed a battery that can charge to full capacity in less than one minute, store energy at similar densities to lithium-ion batteries and isn’t prone to catching on fire, reports Alex Wilkins for New Scientist. “Although the battery operates at the comparatively high temperature of 110°C (230°F),” writes Wilkins, “it is resistant to fire because it uses an inorganic salt that can’t burn as its electrolyte, the material that allows charge to flow inside a battery.” Sadoway explains that “this is a totally new battery chemistry."
Researchers at MIT have developed an artificial intelligence sensor that can track the progression of Parkinson’s disease in patients based on their breathing while they sleep, reports Conor Hale for Fierce Biotech. “The device emits radio waves and captures their reflection to read small changes in its immediate environment,” writes Hale. “It works like a radar, but in this case, the device senses the rise and fall of a person’s chest.”
MIT researchers have developed a new artificial intelligence system that uses a person’s breathing pattern to help detect Parkinson’s sisease, reports Susannah Sudborough for Boston.com. “The device emits radio signals, analyzes reflections off the surrounding environment, and monitors the person’s breathing patterns without any bodily contact,” writes Sudborough.
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.
