Researchers at MIT have found a new “iteration of a foundational quantum experiment,” reports Gayoung Lee for Gizmodo. They “successfully replicated the double-slit experiment on the atomic scale, allowing for an unprecedented level of empirical precision,” writes Lee. “By using supercold atoms as ‘slits’ for light to pass through, the team confirmed that the wave-particle duality of light—with all its paradoxical properties—holds up even on the most fundamental quantum scales.”
Physicists at MIT have provided new insights into the world of quantum mechanics after successfully performing the double-slit experiment with “incredible atomic precision,” reports Mrigakshi Dixit for Interesting Engineering. The researchers “discovered a clear relationship: the more precisely they determined a photon’s path (confirming its particle-like behavior), the more the wave-like interference pattern faded,” explains Dixit. “The researchers observed that the wave interference pattern weakened any time an atom was nudged by a photon passing by. This confirmed that getting information about the photon’s route automatically erased its wave-like properties.”
The US Air Force has renewed a longstanding contract for the continued operation of MIT Lincoln Laboratory, reports Don Seiffert for Boston Business Journal. Lincoln Laboratory’s research is “essential to a robust defense sector and to addressing the rapidly evolving nature of world conflict,” says Ian Waitz, MIT’s vice president for research. “Its rapid prototyping has saved the lives of U.S. service members and supported responses to domestic crises.” He adds that research at Lincoln also “goes to the private sector, enhancing both the nation’s technological advantage and its manufacturing prowess.”
Researchers at CSAIL have created three “libraries of abstraction” – a collection of abstractions within natural language that highlight the importance of everyday words in providing context and better reasoning for large language models, reports Darren Orf for Popular Mechanics. “The researchers focused on household tasks and command-based video games, and developed a language model that proposes abstractions from a dataset,” explains Orf. “When implemented with existing LLM platforms, such as GPT-4, AI actions like ‘placing chilled wine in a cabinet' or ‘craft a bed’ (in the Minecraft sense) saw a big increase in task accuracy at 59 to 89 percent, respectively.”
MIT physicists have “successfully placed two dysprosium atoms only 50 nanometers apart—10 times closer than previous studies—using ‘optical tweezers,’” reports Darren Orf for Popular Mechanics. Utilizing this technique can allow scientists to “better understand quantum phenomena such as superconductivity and superradiance,” explains Orf.
A more than $40 million investment to add advanced nano-fabrication equipment and capabilities to MIT.nano will significantly expand the center’s nanofabrication capabilities, reports Jon Chesto for The Boston Globe. The new equipment, which will also be available to scientists outside MIT, will allow “startups and students access to wafer-making equipment used by larger companies. These tools will allow its researchers to make prototypes of an array of microelectronic devices.”
Popular Mechanics reporter Jill Waldbieser spotlights Prof. Hugh Herr and his work developing prosthetic limbs that integrate with their human hosts using a surgical technique that preserves the sensation in artificial limbs. “In the future, on the order of five years or so, we’ll be so good at this, we’ll completely restore the signals from the prosthetic to the brain and from the brain to the prosthetic, like the limb was never amputated,” says Herr.
Wall Street Journal reporter John Anderson spotlights “Augmented” a new PBS documentary featuring Prof. Hugh Herr and his work in robotic limbs and surgery.
A new documentary titled “Augmented” spotlights Prof. Hugh Herr and his work developing bionic limbs at the MIT Media Lab, reports Dana Gerber for The Boston Globe. “The long-term hope for the procedure is that people with Ewing amputations will be able to further adapt to the bionic limbs shown in the film, which Herr’s team is developing at MIT,” writes Gerber.
A new amputation technique being developed by MIT researchers provides patients with more sensory feedback from prosthetic limbs, writes Anjana Ahuja for the Financial Times. “The technique could transform the way that amputation has long been viewed,” writes Ahuja, “not as a last-resort method that subtracts from the body but an act of rejuvenation with the potential to restore a sense of completeness.”
Here & Now’s Scott Tong speaks with Gideon Gil of STAT about a new technique for amputation surgery developed by researchers from MIT and Brigham and Women’s Hospital that recreates muscle connections and restore the brain’s ability to sense where and how one’s limbs are moving.
Researchers from MIT have developed a new kind of surgery that could offer amputees better control of their muscles and prosthetic limbs after surgery, reports Cara Murez for U.S. News & World Report. “In this new type of surgery — called agonist-antagonist myoneural interface, or AMI — surgeons reconnect those muscle pairs so they retain the push-pull relationship they've always had and improve sensory feedback,” writes Murez.
Mashable spotlights how MIT researchers have developed a new type of amputation surgery that could “help amputees better control their residual muscles and sense where their ‘phantom limb’ is in space.”
Postdoc Shriya Srinivasan has devised a new way to perform amputation surgery that would reconnect dangling nerves to the skin and help restore a patient’s sense of touch, reports Anissa Gardizy for The Boston Globe. “I would hope that in the next 10 years, people are offered the ability to have these advanced techniques incorporated into their initial surgery,” she said.
Research published in Science Translational Medicine suggests that inflammation caused by tumor removal surgery may actually encourage the emergence of new tumors. Daniel Uria for UPI reports that the study, led by Prof. Robert Weinberg, identified “perioperative anti-inflammatory treatment” as a way to substantially reduce the likelihood of “early metastatic recurrence in breast cancer patients.”
