Everything is a Brand

Reasserting U.S. leadership in microelectronics

January 19, 2022

The global semiconductor shortage has grabbed headlines and caused a cascade of production bottlenecks that have driven up prices on all sorts of consumer goods, from refrigerators to SUVs. The chip shortage has thrown into sharp relief the critical role semiconductors play in many aspects of everyday life. But years before the pandemic-induced shortage took hold, the United States was already facing a growing chip crisis. Its longstanding dominance in microelectronics innovation and manufacturing has been eroding over the...

A new way to perform “general inverse...

January 18, 2022

Researchers have discovered a novel way to perform “general inverse design” with reasonably high accuracy. This breakthrough paves the way for further development of a burgeoning and fast-moving field that could eventually enable the use of machine learning to accurately identify materials based on a desired set of user-defined properties. This could be revolutionary for materials science and have vast industrial benefits and use cases. The work was led by researchers from the Low Energy Electronic Systems (LEES) interdisciplinary...

“Hey, Alexa! Are you trustworthy?”

January 14, 2022

A family gathers around their kitchen island to unbox the digital assistant they just purchased. They will be more likely to trust this new voice-user interface, which might be a smart speaker like Amazon’s Alexa or a social robot like Jibo, if it exhibits some humanlike social behaviors, according to a new study by researchers in MIT’s Media Lab. The researchers found that family members tend to think a device is more competent and emotionally engaging if it can...

Clean room as classroom

January 14, 2022

MIT undergraduates are using labs at MIT.nano to tinker at the nanoscale, exploring spectrometry, nanomaterial synthesis, photovoltaics, sensor fabrication, and other topics. They’re also getting an experience not common at the undergraduate level — gowning up in a bunny suit and performing hands-on research inside a clean room. During the fall 2021 semester, these students were part of 6.S059 (Nanotechnology — Design From Atoms to Everything) and 6.A06 (First.nano! – Fabricate Your Own Solar Cell in MIT.nano Cleanroom), two...

Seeing the natural world through a mathematical...

January 13, 2022

Growing up in Wallingford, Connecticut, David Darrow loved spending time outside, hiking and camping with his Boy Scout troop. He was fascinated by the environment around him, constantly asking questions about the natural world. Now a senior at MIT majoring in math and minoring in German and physics, Darrow is still studying natural phenomena. With fluid dynamics and climate modeling as his primary fields of interest, he loves to use math as a way to explore the world around...

Pricing carbon, valuing people

January 12, 2022

In November, inflation hit a 39-year high in the United States. The consumer price index was up 6.8 percent from the previous year due to major increases in the cost of rent, food, motor vehicles, gasoline, and other common household expenses. While inflation impacts the entire country, its effects are not felt equally. At greatest risk are low- and middle-income Americans who may lack sufficient financial reserves to absorb such economic shocks. Meanwhile, scientists, economists, and activists across the...

Four with MIT ties honored with 2022...

January 12, 2022

Four mathematicians with MIT ties were recently honored by the American Mathematical Society (AMS). Professors Michel Goemans and Richard Stanley, along with Cornell University Professor David Williamson PhD ’93, are recipients of AMS’s Leroy P. Steele Prizes for 2022. Associate Professor Semyon Dyatlov received the inaugural 2022 Mikhail Gordin Prize, offered jointly by the AMS and the European Mathematical Society (EMS). All four will be recognized for their achievements at January’s 2022 Joint Mathematics Meetings in Seattle. They will be joined by two MIT...

Three with MIT ties win 2022 Churchill...

January 12, 2022

MIT seniors David Darrow and Tara Venkatadri have been selected as 2022 Churchill Scholars and will embark on a year of graduate studies in the U.K. starting next fall. James Diao, a graduate student in the Harvard-MIT Program in Health Sciences and Technology (HST), received the Kanders Churchill Scholarship in Science Policy. The Churchill Scholarship is a highly competitive fellowship that annually offers 16 American students the opportunity to pursue a funded graduate degree in science, mathematics or engineering...

Synthesis too slow? Let this robot do...

January 11, 2022

Researchers in the lab of Bradley Pentelute, MIT professor of chemistry, have invented a fully automated fast-flow instrument that can synthesize peptide-nucleic acids in a single shot. By automating the process of synthesizing CPP-conjugated peptide-nucleic acids (PPNAs) using the robot dubbed “Tiny Tides” by the research team, typical PPNA synthesis time was reduced from multiple days to just two hours. “This new efficient technology represents a potential major step forward to enable on-demand rapid production of candidate antisense oligonucleotides,...

Q&A: Dolapo Adedokun on computer technology, Ireland,...

January 11, 2022

Adedolapo Adedokun has a lot to look forward to in 2023. After completing his degree in electrical engineering and computer science next spring, he will travel to Ireland to undertake an MS in intelligent systems at Trinity College Dublin as MIT’s fourth student to receive the prestigious George J. Mitchell Scholarship. But there’s more to Adedokun, who goes by Dolapo, than just academic achievement. Besides being a talented computer scientist, the senior is an accomplished musician, an influential member of student...

A look at how countries go nuclear...

January 11, 2022

In 1993, South Africa announced to a largely surprised world that it had built nuclear weapons in the 1980s, before dismantling its arsenal. For the first time, a country outside of the elite world powers had obtained nuclear capabilities while keeping matters a secret from almost everyone else. To this day, South Africa remains the only country to have pulled off that exact trick. Other countries have gone nuclear in other ways. A half-dozen countries with more economic and...

In Down syndrome cells, genome-wide disruptions mimic...

January 10, 2022

In Down syndrome, the third copy of chromosome 21 causes a reorganization of the 3D configuration of the entire genome in a key cell type of the developing brain, a new study shows. The resulting disruption of gene transcription and cell function are so similar to those seen in cellular aging, or senescence, that the scientists leading the study found they could use anti-senescence drugs to correct them in cell cultures. The study published in Cell Stem Cell therefore...

Method for delivering immune system-stimulating drugs may...

January 10, 2022

Stimulating the body’s immune system to attack tumors is a promising way to treat cancer. Scientists are working on two complementary strategies to achieve that: taking off the brakes that tumors put on the immune system; and “stepping on the gas,” or delivering molecules that jumpstart immune cells. However, when jumpstarting the immune system, researchers have to be careful not to overstimulate it, which can cause severe and potentially fatal side effects. A team of MIT researchers has now...

A dirt cheap solution? Common clay materials...

January 10, 2022

Methane is a far more potent greenhouse gas than carbon dioxide, and it has a pronounced effect within first two decades of its presence in the atmosphere. In the recent international climate negotiations in Glasgow, abatement of methane emissions was identified as a major priority in attempts to curb global climate change quickly. Now, a team of researchers at MIT has come up with a promising approach to controlling methane emissions and removing it from the air, using an...

Richard Cohen: Pioneering biomedical research and education...

January 7, 2022

Richard J. Cohen, the Whitaker Professor in Biomedical Engineering in the MIT Institute for Medical Engineering and Science (IMES) and a faculty member in the Harvard-MIT Program in Health Sciences and Technology (HST), has seen a lot during his years at MIT. He is a rare “MIT lifer,” rising from student to senior faculty member and spending half a century at the Institute. Cohen joined HST as a first-year medical student in 1971 and then inaugurated the MD/PhD track...
