A new study by MIT researchers provides evidence that babies and toddlers understand people have a close relationship if they are willing to share saliva via sharing food or kissing, reports Nell Greenfieldboyce for NPR. "From a really young age, without much experience at all with these things, infants are able to understand not only who is connected but how they are connected," says postdoc Ashley Thomas. "They are able to distinguish between different kinds of cooperative relationships."
Boston Globe reporter Pranshu Verma spotlights MIT startup Biobot Analytics, co-founded by Mariana Matus ’18 and Newsha Ghaeli ’17, for their work studying sewage data to better predict the spread of Covid-19 in communities. “For health officials, it [the data] confirms whether Covid spikes in the community are real, and not due to increased testing or other factors,” writes Verma. “Moreover, Covid levels in waste water are a leading indicator for new clinical cases, giving health officials a few days’ notice if they’ll see more sick patients showing symptoms.”
MIT scientists have discovered that infants use saliva sharing as a cue in distinguishing close relationships, reports Andrew Joseph for STAT. “Saliva-sharing interactions provide externally observable cues of thick relationships, and young humans can use these cues to make predictions about subsequent social interactions,” the researchers explain.
Science reporter Bridget Alex spotlights a new study by MIT researchers that finds children as young as 8-months-old can infer the social significance in swapping saliva with those they are closely bonded with. This is a “big step in this new science of what preverbal infants already know about human sociality,” explains Prof. Alan Fiske of the University of California, Los Angeles.
The Haystack Observatory will be hosting a virtual climate change forum on Jan. 27, featuring Haystack’s director Colin Lonsdale and research scientist Pedro Elosegui, reports John Laidler for The Boston Globe. “Lonsdale will provide general information about the work of Haystack and climate science,” writes Laidler. “Elosegui will discuss Haystack’s polar research, which includes studies of global climate and sea-level change.”
A new study by MIT researchers finds people are more likely to interact with a smart device if it demonstrates more humanlike attributes, reports Brian Heater for TechCrunch. The researchers found “users are more likely to engage with both the device — and each other — more when it exhibits some form of social cues,” writes Heater. “That can mean something as simple as the face/screen of the device rotating to meet the speaker’s gaze.”
STAT reporters Katie Palmer and Casey Ross spotlight how Prof. Regina Barzilay has developed an AI tool called Mirai that can identify early signs of breast cancer from mammograms. “Mirai’s predictions were rolled into a screening tool called Tempo, which resulted in earlier detection compared to a standard annual screening,” writes Palmer and Ross.
Popular Science reporter Rahul Rao writes that researchers from MIT and Harvard have whipped up quantum tornadoes, “the latest demonstration of quantum mechanics—the strange code of laws that governs the universe at its finest, subatomic scales.”
Fast Company reporter Clint Rainey writes that a new study co-authored by MIT economists finds that the bulk of the loan money handed out through the Paycheck Protection Program (PPP) helped business owners and shareholders. The researchers estimate that “somewhere between 23% and 34% of PPP dollars went to workers who would’ve otherwise lost their jobs,” writes Rainey. “The rest of the loan money—a full two-thirds to three-fourths—landed in the pockets of either the company’s owners or shareholders.”
Salon reporter Elizabeth Landau spotlights the work of researchers from MIT and the Massachusetts Eye and Ear Infirmary in uncovering how Covid-19 can affect the ear. Viruses such as Covid-19, “all have these tentacles that seem to touch the ear, but nobody’s been able to study them because the ear is so inaccessible,” says Prof. Lee Gehrke. “So that’s the part that I think I get most excited about. Now we have a way to look at these things in a way that we were not able to do before.”
USA Today reporter Karen Weintraub spotlights Prof. Li-Huei Tsai’s work studying a potential new approach to treating Alzheimer's disease and “whether certain tones of sound and frequencies of light can help regulate brain waves and help clear our cellular trash, including toxic proteins.” Tsai explains that: “The major difference between this approach and all other approaches is that this approach doesn’t just target one molecule or one pathway or one cell type. This is a holistic approach to take care of the whole system.”
CNBC reporter Jennifer Liu spotlights a new study by researchers from the Sloan School of Management who found that the biggest factor that leads people to quit their jobs is a toxic work culture. Senior lecturer Donald Sull says, “what’s significant is that toxic workplace factors lead to a ‘stronger reaction’ – quitting – more so than other bad work issues,” writes Liu.
A series of recently tested hypersonic missiles in North Korea brings forth concerns about vulnerability for U.S. troops and their allies in Asia, reports Josh Smith for Reuters. Research affiliate David Wright warns that “South Korea and the roughly 28,500 U.S. troops based there are so close that incoming missiles could fly on even lower trajectories, with a much shorter flight time, making defense more difficult,” writes Smith.
Researchers from MIT and Harvard have directly observed a quantum tornado, reports Elizabeth Gamillo for Smithsonian. “Scientists observed the tornado-like behavior after trapping and spinning a cloud of one million sodium atoms using lasers and electromagnets at 100 rotations per second,” writes Gamillo.
MIT researchers have developed a new technique for producing low-voltage, power-dense actuators that can propel flying microrobots, reports Danica D'Souza for Mashable. “The new technique lets them make soft actuators that can carry 80 percent more payload,” D’Souza reports.
