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.
Writing for Forbes, Prof. Daniela Rus, director of CSAIL, makes the case that liquid neural networks “offer an elegant and efficient computational framework for training and inference in machine learning. With their compactness, adaptability, and streamlined computation, these networks have the potential to reshape the landscape of artificial intelligence and drive further breakthroughs in the field.”
Sublime Systems, a startup founded by Prof. Yet-Ming Chiang and former MIT postdoc Leah Ellis, is working to decarbonize cement making – a process which currently accounts for eight percent of global carbon emissions. “The world has a huge appetite for cement, and Sublime is working to scale its production to meet it,” writes Casey Crownhart for The Spark, MIT Technology Review’s weekly climate newsletter.
MIT researchers have discovered an RNA-guided DNA-cutting enzyme in eukaryotes, reports Science. “The researchers speculate that eukaryotic cells may have gained the newly identified editing genes from transposable elements—so-called jumping genes—they received from bacteria,” writes Science.
Prof. Richard Young and his colleagues have discovered that many transcription factors can bind RNA, reports Christie Wilcox for Science. "The team decided to investigate after scattered reports suggested that at least some transcription factors are capable of binding RNA even though they lack traditional RNA binding domains,” writes Wilcox.
A new study co-authored by MIT scientists finds that the Department of Justice’s China Initiative may have caused researchers of Chinese descent to leave the U.S. for China, reports Ryan Quinn for Inside Higher Ed. The study authors found that researchers of Chinese descent had “general feelings of fear and anxiety that lead them to consider leaving the United States and/or stop applying for federal grants. If the situation is not corrected, American science will likely suffer the loss of scientific talent to China and other countries.”
Professor Roberto Rigobon, Research Scientist Florian Berg and Research Affiliate Julian Kölbel write for the Financial Times about the pressing need for tougher scrutiny, regulation and reform of ESG rating agencies. “The solution is greater transparency about what a rating seeks to measure, and the methodology behind it,” they write. “Users should be able to scrutinize the way the data is collected and aggregated, and whether that is consistent with the rating’s objective.”
MIT researchers have identified a new biological editing system that could “potentially be even more precise than CRISPR gene editing,” reports Laura Baisas for Popular Science. The new system, based on a protein called Fanzor, is “the first programmable RNA-guided system discovered in eukaryotes,” Baisas notes.
Researchers from MIT and elsewhere have found that new building codes put in place to combat climate change could impact home affordability in the greater Boston area, reports Paula Ebben for CBS Boston, “If widely adopted, [the codes] could add up to $23,000 to the cost of an average home, leaving an additional 33,000 Massachusetts residents priced out of the market,” writes Ebben.
Researchers from MIT and Duke have discovered that introducing weaker bonds into a material can produce stronger polymers, reports Norbert Sparrow for Plastics Today. “Side-chain cross-linked polymers are probably the most widely used type of polymer network,” says postdoc Shu Wang. “The concept [outlined] in our paper should work for all polymer networks that are side-chain cross linked.”
A study from MIT and elsewhere has found that a new building code in Massachusetts designed to promote “net zero” development, “would increase construction costs and potentially worsen the state’s housing crisis,” reports Greg Ryan for NBC Boston.
Researchers at MIT have developed an extra-absorbent hydrogel that can draw water from the air, reports Ross Cristantiello for Boston.com. The new hydrogel “could potentially help communities ravaged by drought and make air conditioners more energy-efficient,” writes Cristantiello.
Prof. Yet-Ming Chiang co-founded Sublime Systems, a company that has developed a new method for producing cement that is powered by electrochemistry instead of fossil fuel-powered heat, reports Catherine Clifford for CNBC. “I believe climate change has pushed all of us into an extremely fertile, creative period that will be looked back on as a true renaissance,” says Chiang. “After all, we're trying to re-invent the technological tools of the industrial revolution. There's no shortage of great problems to work on! And time is short.”
Prof. Marzyeh Ghassemi speaks with Yahoo News reporter Rebecca Corey about the benefits and risks posed by the use of AI tools in health care. “I think the problem is when you try to naively replace humans with AI in health care settings, you get really poor results,” says Ghassemi. “You should be looking at it as an augmentation tool, not as a replacement tool.”
Postdoc Josh Borrow and his colleagues used simulations to explore how early-universe galaxies born inside alternative dark matter halos start out, and what happens as they grow, reports Lyndie Chiou for Scientific American. “The simulations also revealed a new discovery: a connection between alternative dark matter types and starbursts, periods of extremely rapid star formation inside a galaxy.”
