Using machine learning techniques, MIT researchers have detected “X particles” produced by the Large Hadron Collider, reports Rahul Rao for Popular Science. “The results tell us more about an artifact from the very earliest ticks of history, writes Rao. “Quark-gluon plasma filled the universe in the first millionths of a second of its life, before what we recognize as matter—molecules, atoms, or even protons or neutrons—had formed.”
Prof. Mircea Dincǎ, Prof. Evelyn Ning-Yi Wang, Prof. Ian W. Hunter, Prof. Guoping Feng, and Senior Research Scientist David H. Shoemaker were elected as Fellows of AAAS for their efforts on behalf of the advancement of science and its applications to better serve society, reports Science.
Prof. Sara Seager speaks with Boston Globe reporter Matt Yan about how she plans to use the James Webb Space Telescope to compare when an exoplanet is in front of a star and when it is not. “By comparing those two measurements, they’re going to be a tiny bit different,” says Seager, adding that when the planet "in front of the start is blocking some of the starlight, in particular, the atmosphere blocks some of the starlight, and so we can tell what’s in the planet atmosphere.”
TESS, a NASA mission led and operated by MIT, has discovered over 5,000 planets candidates outside of our solar system, reports Ed Browne for Newsweek. “This time last year, TESS had found just over 2,400 TOIs (TESS Objects of Interest),” says postdoctoral associate Michelle Kunimoto. “Today, TESS has reached more than twice that number – a huge testament to the mission and all the teams scouring the data for new planets.”
Scientists have discovered “X-particles” in the aftermath of collisions produced in the Large Hadron Collider, which could shed light on the structure of these elusive particles, reports Becky Ferreira for Vice. “X particles can yield broader insights about the type of environment that existed in those searing and turbulent moments after the Big Bang,” writes Ferreira.
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."
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.
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.”
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.”
Science Friday host Ira Flatow spotlights how Prof. Scott Hughes has shifted the wavelengths of gravitational waves into the range of human hearing, creating an audible experience that allows listeners to experience the “ripples in space-time made by the tremendous mass of colliding black holes.”
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.
STAT reporter Megan Molteni writes that a new study by MIT researchers finds that senescent cells, which are linked to aging, may potentially be a cause of Down syndrome. “We hope it opens up new avenues for how we look at Down syndrome — that there seems to be this whole other element that plays on a different timeline that we really need to explore more.”
Renaldo Webb ’10 founded PetPlate, a fresh-cooked pet food company that delivers personalized meal plans directly to pet owners, reports Igor Bosilkcovski for Forbes. “Webb got the idea for the company when he worked with pet food companies as a consultant, and was able to realize that the low quality ingredients in the pet food had been the underlying reason for many health issues with pets, particularly obesity,” writes Bosilkcovski.
Popular Science reporter Nikita Amir writes that a new study co-authored by MIT researchers finds has identified a chemical pathway by which life could make a home for itself in Venus’ toxic clouds by producing ammonia. “Life on Venus, if it exists, is not like life on Earth,” says research affiliate Janusz Petkowski. “It’s life as we don’t know it. The only question is, to what degree it is different?”
