MIT scientists have “observed and captured images of a rare ‘edge state’ in ultracold atoms,” reports Rupendra Brahambhatt for Interesting Engineering. “Using these findings, they can learn to achieve and harness the edge states of electrons in different materials,” notes Brahambhatt. “This breakthrough in the field of quantum physics could lead to the discovery of practically infinite energy sources.”
Researchers at MIT have created a noise-blocking sheet of silkworm silk that could “greatly streamline the pursuit of silence,” reports Andrew Chapman for Scientific American. “The silk sheet, which is enhanced with a special fiber, expands on a technology also found in noise-canceling headphones,” explains Chapman. “These devices create silence by sampling the ambient noise and then emitting sound waves that are out of phase with those in the environment. When the ambient and emitted waves overlap, they cancel each other out.”
Researchers at MIT have developed a fiber capable of suppressing sound that is made up of “silk, canvas and other common materials,” reports Charlie McKenna for MassLive. “The silk is barely thicker than human hair and is made by heating the materials and drawing them into a fiber,” explains McKenna. “Since each material flows at the same temperature, they can be pulled into a fiber while maintaining their structure.”
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.
MIT researchers have developed “an ultra-thin silk fabric embedded with a special piezoelectric fiber that can vibrate to cancel out noise in a room,” reports Bob McDonald for CBC. “The researchers want to further study how changing elements of the fabric — such as the number of piezoelectric fibers and the voltage they apply to it, the direction they're sewn into the fabric, and the size of the pores in the fabric — can improve on their findings,” writes McDonald.
Interesting Engineering reporter Sujita Sinha spotlights how MIT researchers crafted a special silk fabric capable of blocking sound. “Inside this special material is a fiber that springs to life when an electrical charge is applied,” explains Sinha. “The fabric starts shaking when it hears sound, which helps stop noise in two different ways.”
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.”
President Biden has awarded Prof. Emeritus Subra Suresh ScD '81, the former dean of the MIT School of Engineering, the National Medal of Science for his “pioneering research across engineering, physical sciences, and life sciences,” reports Alexa Gagosz for The Boston Globe. Prof. James Fujimoto '79, SM '81, PhD '84, research affiliate Eric Swanson SM '84, and David Huang '85, SM '89, PhD '93 were awarded the National Medal of Technology and Innovation, “the nation’s highest award for technical achievement.”
STAT reporter Annalisa Merelli writes that the 2023 Lasker Award has been given to Prof. James Fujimoto, research affiliate Eric Swanson SM ’84 and David Huang PhD ’93 for their work advancing the diagnosis of eye disease. Fujimoto, Swanson and Huang developed “optical coherence tomography (OCT) — the first noninvasive technology allowing doctors to see high-resolution images of the retina.”
Prof. James Fujimoto, research affiliate Eric Swanson SM ’84 and David Huang PhD ’93 have won a Lasker Award for their work inventing optical coherence tomography, which can “detect conditions like macular degeneration and diabetic retinopathy earlier than previous methods, preventing blindness,” reports Noah Weiland and Cade Metz for The New York Times. “O.C.T. now is commonly used in ophthalmology offices, where the patient simply rests a chin and forehead against an instrument for a brief scan,” write Weiland and Metz. “The method, invented in 1991, offers a staggering amount of detail about the retina.”
Prof. James Fujimoto, research affiliate Eric Swanson SM ’84 and David Huang PhD ’93 have been honored with the Lasker Award for their work for their work inventing “imaging technology that revolutionized how ophthalmologists diagnose diseases of the eye," reports Jonathan Saltzman for The Boston Globe. The scientists were recognized for developing “optical coherence tomography, or OCT, the first technology that enabled doctors to see a two- and three-dimensional cross-sectional image of the retina,” Saltzman explains. “This painless scan takes less than 10 minutes, and is now the standard of care for diagnosing retina diseases.”
Researchers at MIT have developed a soft robot that can be controlled by a weak magnetic field and travel through tiny spaces within the human body, reports Andrew Paul for Popular Science. “Because of their soft materials and relatively simple manipulation, researchers believe such mechanisms could be used in biomedical situations, such as inching through human blood vessels to deliver a drug at a precise location,” explains Paul.
Prof. Jongyoon Han and research scientist Junghyo Yoon have developed a new portable desalination device that can deliver safe drinking water at the push of a button, reports Meghan Gunn and Kerri Anne Renzulli for Newsweek. The device “requires less power than a cell phone charger to run and produces clean drinking water that exceeds World Health Organization standards,” writes Gunn and Renzulli.
MIT engineers have developed a new technique that enables bug-sized aerial robots to handle a sizeable amount of damage and still fly, reports Andrew Paul for Popular Science. “The new repair techniques could come in handy when using flying robots for search-and-rescue missions in difficult environments like dense forests or collapsed buildings,” writes Paul.
Researchers at MIT have predicted that without improvements in hardware efficiency, energy consumption and emissions from autonomous vehicles could be “comparable to that of data centers today,” reports Sarah Wells for Popular Mechanics. “In order to reduce the future carbon footprint of AVs, scientists will need to make the computing systems of AVs, including smart sensors, far more efficient,” writes Wells.
