MIT scientists have found that silent synapses - a type of memory-forming synapse - are present in the adult brain, reports The Economist. The discovery of these silent synapses, explains Prof. Mark Harnett, “is a lever for us to get into understanding learning in adults and how potentially we can get access to make it not degrade over the course of aging or disease.”
Prof. Daron Acemoglu speaks with Politico reporter Derek Robertson about his new study examining the impacts of automation on the workforce and economy. “This discussion gets framed around ‘Will robots and AI destroy jobs, and lead to a jobless future,’ and I think that's the wrong framing,” says Acemoglu. “Industrial robots may have reduced U.S. employment by half a percent, which is not trivial, but nothing on that scale [of a “jobless future”] has happened — but if you look at the inequality implications, it's been massive.”
Research affiliate Ramin Hasani speaks with Kimberly Adams of Marketplace about how he and his CSAIL colleagues solved a differential equation dating back to the early 1900s, enabling researchers to create an AI algorithm that can learn on the spot and adapt to evolving patterns. The new algorithm “will enable larger-scale brain simulations,” Hasani explains.
Prof. Kieran Setiya’s book “Life is Hard: How Philosophy Can Help Us Find Our Way,” has been named one of The Economist’s best books of 2022. In the book, Setiya makes the case that “suffering need not dimmish or spoil a good life,” writes The Economist.
Prof. Robert Langer and his colleagues write for Physics Today about how physics could help contribute to predicting tissue behaviors and accelerate the regeneration of human tissues and organs. “The physics of tissue engineering in general and of bioprinting in particular is a relatively new field that could provide numerous opportunities for tissue and organ fabrication and regeneration,” they write.
An MIT research study suggests that those with the E4 variant of the APOE gene are more likely to develop Alzheimer’s symptoms, reports William A. Haseltine for Forbes. The variant “disrupts how fat molecules are processed in the brain,” writes Haseltine. “It appears that the disruption of these fat molecules could be the fundamental reason why those that contain the E4 variant are more likely to develop Alzheimer’s symptoms.”
The Verge reporter Justine Calma writes that a new study by MIT researchers finds that while wind energy has measurably improved air quality, only 32% of those benefits reached low-income communities. “The research shows that to squeeze out the greatest health benefits, wind farms need to intentionally replace coal and gas power plants,” writes Calma. “And to clean up the most polluted places — particularly those with more residents of color and low-income households — those communities need to be in focus when deploying new renewable energy projects.”
A new study by MIT researchers finds that increased usage of wind power is improving air quality in parts of the U.S., however only a third of the health benefits are being seen in disadvantaged communities, reports Alan Mozes for HealthDay. "Going forward," explains Prof. Noelle Selin, "more targeted policies are needed to reduce the disparities at the same time, for example by directly targeting [fossil fuel] sources that influence certain marginalized communities."
A new study by Prof. Daron Acemoglu, former postdoctoral fellow Nicolaj Mühlbach and London School of Economics Prof. Andrew Scott finds that while American jobs have become age-friendlier, “older workers haven’t been the biggest beneficiaries of this age-friendly job bonanza,” reports Andrew Van Dam for The Washington Post. The researchers found, “workers age 62 and older were significantly more willing to accept a smaller paycheck if a job involved moderate physical activity, more time sitting and the autonomy to choose how to do their job,” writes Van Dam.
Increased usage of wind energy has led to health benefits, but does not affect all communities equally, reports Saul Elbein for The Hill. The researchers found that in order to increase the benefits of wind energy, “the electricity industry would have to spin down the most polluting plants at times of high wind-supply — rather than their most expensive ones,” writes Elbein.
Physicists from MIT and elsewhere have created a small “wormhole” effect between two quantum systems on the same processor and were able to send a signal through it, reports Charlotte Hu for Popular Science. This new model is a “way to study the fundamental problems of the universe in a laboratory setting,” writes Hu.
Cognito Therapeutics, founded by Prof. Ed Boyden and Prof. Li-Huei Tsai, has secured a large-scale trial to test a new device aimed at treating Alzheimer’s disease, reports Sarah McBride for Bloomberg.
Researchers at MIT and elsewhere have created a holographic wormhole using Google’s Sycamore quantum computer, reports Sarah Wells for Vice. “The researchers created an entangled state (a quantum mechanical phenomena where distant particles can still communicate with each other) between two halves of a quantum computer and sent a message in between,” writes Wells. “This message was scrambled as it entered the system and, through entanglement, unscrambled on the other side.”
CNN’s Ashley Strickland highlights a study by MIT researchers finding that a mysterious flash of light was caused by a black hole jet pointing directly at Earth. The researchers determined that the flash of light was “100 times more powerful than the most powerful gamma-ray burst afterglow,” explains research scientist Dheeraj “DJ” Pasham.
A team of researchers, including scientists from MIT, “simulated a pair of black holes in a quantum computer and sent a message between them through a shortcut in space-time called a wormhole,” reports Dennis Overbye for The New York Times. The development is another “step in the effort to understand the relation between gravity, which shapes the universe, and quantum mechanics, which governs the subatomic realm of particles,” writes Overbye.
