Dr. Jay Last ’56, the founder of Fairchild Semiconductor Corp, died on Nov. 11, reports James R. Hagerty for The Wall Street Journal. Dr. Last figured out “ways to manufacture integrated circuits in bulk, helping to put the silicon into Silicon Valley and make the region a synonym for digital technology,” writes Hagerty.
A team of astronomers, including MIT researchers, has discovered an ultrahot Jupiter that orbits its star in just 16 hours, reports Robert Lea for Newsweek. “Ultrahot Jupiters such as TOI-2109b constitute the most extreme subclass of exoplanet,” explains former MIT postdoc Ian Wong. “We have only just started to understand some of the unique physical and chemical processes that occur in their atmospheres – processes that have no analogs in our own solar system.”
Wired reporter Adam Rogers spotlights Prof. Nancy Kanwisher’s research on the fusiform face area, which becomes active when a person sees a face, and what would happen if the area were intentionally activated. Kanwisher’s experiment “certainly suggested the possibility, the power, of jacking directly into the brain,” writes Rogers.
Andy Rivkin ’91 speaks with Boston Globe reporter Andrew Brinker about his work on NASA’s DART mission, which is aimed at testing whether a rocket could be used to help steer an asteroid away from Earth. “I’ve always been interested in stars and space and planets since I was a kid,” said Rivkin. “At MIT, I was in the earth, atmospheric, and planetary sciences department, and that’s when I started looking at asteroids. And then as a graduate student, I studied asteroids. And then I ended up doing my dissertation on them. It sort of all started [at MIT].”
Scientists from MIT have observed a quantum effect that blocks ultracold atoms from scattering light, reports Emily Conover for Science News. To observe the effect, the researchers “beamed light through a cloud of lithium atoms, measuring the amount of light it scattered,” writes Conover. “Then, the team decreased the temperature to make the atoms fill up the lowest energy states, suppressing the scattering of light.”
Prof. Ernest Moniz speaks with On Point host Meghna Chakrabarti about President Biden’s recent infrastructure bill and the future of nuclear power in the United States. “Climate change is the problem of our time,” says Moniz. “And we need every tool at our disposal to address that. It’s about the emissions, not about one’s favorite or disfavorite technology and I think that’s the way we have to look at this. It’s all about getting to low carbon.”
A new study by MIT scientists has uncovered evidence of Pauli blocking, confirming that as atoms are chilled and squeezed to extremes their ability to scatter light is suppressed, reports Leah Crane for New Scientist. “This is a very basic phenomenon, but it’s sort of a devil to see,” explains former MIT postdoc Yair Margalit. “You need these extreme conditions to be able to see it – high densities and ultra-low temperatures – and it is difficult to get both of these at once.”
Prof. Emerita Nancy Hopkins, who has made “significant strides in molecular biology and a tireless advocate for gender equity in science,” has been named the recipient of STAT’s 2021 Biomedical Innovation Award, reports Isabella Cueto for STAT. “It’s very easy to forget how much progress there has been because we haven’t arrived where we’d like to be,” said Hopkins at the 2021 STAT Summit, where she was honored. “So we see the problems that still lie ahead. But you periodically have to pause and say, ‘Oh, my gosh, look how far we came.’”
HuffPost reporter Mary Papenfuss writes that a team of archeologists and scientists, including Research Scientist Jahandar Ramezani, have uncovered evidence of social behaviors in dinosaurs. “The bones were segregated by age, with eggs in a common nesting ground,” writes Papenfuss. “Juveniles likely were left in ‘schools’ while adults foraged.”
Scientific American reporter Dana G. Smith spotlights how Prof. Rebecca Saxe and her colleagues have found evidence that regions of the visual infant cortex show preferences for faces, bodies and scenes. “The big surprise of these results is that specialized area for seeing faces that some people speculated took years to develop: we see it in these babies who are, on average, five or six months old,” Saxe tells Smith.
Research scientist Jahandar Ramezani speaks with Scientific American reporter Christopher Intagliata about his new study that provides evidence early dinosaurs exhibited herding behavior. “This is a critical time in the evolution of dinosaurs. This is pretty early on,” says Ramezani. “So the idea is: this type of behavior, this social behavior, may have actually contributed to the evolutionary success of dinosaurs.”
Writing for the NIH Director’s Blog, Dr. Francis Collins highlights how Prof. Tyler Jacks and research scientist Megan Burger’s work exploring T cell exhaustion led to the creation of a “strategy for developing cancer vaccines that can ‘awaken’ T cells and reinvigorate the body’s natural cancer-fighting abilities.” Collins writes that “the researchers hope to learn if this approach to cancer vaccines might work even better when used in combination with immunotherapy drugs, which unleash the immune system against cancer in other ways.”
Writing for The Guardian, Prof. Daniel Rothman examines the history of Earth’s mass extinctions and how Earth seems to experience “a cascade of disruptions when stressed beyond a tipping point." Rothman writes that: “If we do not significantly cut back CO2 emissions, then we risk passing the threshold before the end of the present century.” He adds, “let us not contribute to the risk of a sixth extinction. Efforts to limit CO2 emissions now may pay dividends further into the future than we can imagine.”
The Naked Scientist podcaster Verner Viisainen spotlights how MIT researchers studied vector-based navigation in humans. “What we discovered is actually that we don’t follow the shortest path but actually follow a different kind of optimization criteria which is based on angular deviation,” says Prof. Carlo Ratti.
Popular Science reporter Charlotte Hu writes that MIT researchers have simulated an environment in which socially-aware robots are able to choose whether they want to help or hinder one another, as part of an effort to help improve human-robot interactions. “If you look at the vast majority of what someone says during their day, it has to do with what other [people] want, what they think, getting what that person wants out of another [person],” explains research scientist Andrei Barbu. “And if you want to get to the point where you have a robot inside someone’s home, understanding social interactions is incredibly important.”
