MIT researchers have developed a biosensor “the size of a stick of gum that can be implanted under the skin and deliver naloxone if vital signs indicate an overdose,” reports David Ovalle and Elana Gordon for The Washington Post. 

MIT researchers have developed a new filtration material, created from natural substances, that could be used to remove “forever chemicals” like PFAS and heavy metals from drinking water, reports Matt Fortin for NBC Boston. "That's a huge advantage of our system, which is that we are using fully renewable, biodegradable and compatible material to resolve this long-lasting problem," explains postdoc Yilin Zhang. 

MIT researchers have developed a new filtration material capable of removing PFAS and heavy metals from water while possessing “antimicrobial properties that prevent the filters from becoming fouled over time,” reports Sujita Sinha for Interesting Engineering. “By combining silk and cellulose and using a method that aligns the silk molecules into nanofibrils, [the researchers] created a hybrid material with unique properties perfect for water filtration,” explains Sinha. 

New Yorker reporter Dhruv Khullar spotlights how researchers from across MIT are using AI to advance drug development. Khullar highlights the MIT Jameel Clinic, the Broad Institute and various faculty members for their efforts in bridging the gap between AI and drug research. “With AI, we’re getting that much more efficient at finding molecules—and in some cases creating them,” says Prof. James Collins. “The cost of the search is going down. Now we really don’t have an excuse.”

A new paper by MIT researchers has found that “aviation safety is improving by the decade,” reports Monica Pitrelli for CNBC. The paper “states that the risk of dying on a commercial flight globally was 1 per 13.7 million passenger boardings from 2018 to 2022 — a significant improvement from the decade before, and far cry from the one death for every 350,000 boardings that occurred between 1968-1977,” explains Pitrelli. 

Researchers at MIT and elsewhere have developed a new device “designed to detect the signs of an overdose and automatically deliver a dose of naloxone in as little as 10 seconds,” reports Tom Hawking for Popular Science. “The device [which has an associated smartphone app] also has a built-in alert system with auditory and tactile signals to wake the user, providing an alternative for those without smartphones or with uncharged devices,” says Prof. Giovanni Traverso. 

Interesting Engineering reporter Shubhangi Dua describes a new implantable device developed by MIT researchers that can detect and automatically treat an opioid overdose. “Having an automated robotic system that can sense and reverse opiate overdose could be transformational,” says Prof. Giovanni Traverso, “particularly for high-risk populations.” 

MIT scientists have developed an implantable sensor that could “detect the signs of an overdose and automatically deliver a dose of naloxone in as little as 10 seconds,” reports Tom Hawking for Popular Science. "The long-term benefits of preventing fatal overdoses and reducing healthcare costs related to overdose treatment are significant factors that support the value of this technology,” explains Prof. Giovanni Traverso. 

A new study by MIT researchers finds that commercial air travel continues to get safer, with the risk of a fatality 1 per every 13.7 million passenger boardings globally in the 2018 to 2022 period, reports Brittany Anas for Forbes. “Researchers explain that this trend in safer flights can be understood through ‘Moore’s Law,’ which is the observation that innovators find ways to double computing power of chips every roughly 18 months,” Anas writes. “However, in this case, the MIT team points out, commercial travel has become almost twice as safe in each decade since the late 1960s.” 

A new study by MIT researchers finds that air travel has never been safer, with the fatality rate falling to 1 per every 13.7 million passenger boardings globally in the 2018-2022 period, reports Agence France-Presse. Prof. Arnold Barnett compared aviation safety increases to "'Moore's Law,’ the famous prediction by Intel founder Gordon Moore that the computing power of chips doubles roughly every 18 months. From 1978-1987 the risk of dying was 1 per 750,000 boarding passengers; from 1988-1997 it was 1 per 1.3 million; and in 1998-2007, 1 per 2.7 million.”  

Forbes reporter Katie Jennings spotlights Phillip (Terry) Ragon '72, and his philanthropic efforts focused on curing HIV. “Ragon’s approach has been to bring together scientists who don’t typically collaborate, including doctors, engineers, physicists, mathematicians and virologists,” writes Jennings.

MIT scientists have shown a simple paper-strip test can detect the flu and identify the specific strain, which could prove useful in improving outbreak response and infection care, writes Dennis Thompson for HealthDay. Jon Arizti-Sanz PhD ’24 says “being able to tease apart what strain or subtype of influenza is infecting a patient has repercussions both for treating them and public health interventions.” 

Researchers from MIT and elsewhere have developed a new technique that removes lead from water using repurposed beer yeast, reports Boston 25 News. The researchers “developed a hydrogel capsule to hold the yeast after it is cleaned, freeze-dried, and ground into a powder,” explains Boston 25. “Researchers said the yeast capsules could be modified to remove other dangerous contaminants from water, including PFAS and microplastics.” 

Researchers at MIT and elsewhere have developed a filter from used brewery yeast capable of removing lead and other metals from water, reports Rich Johnson for NewsNation. “Through a process called biosorption, the yeast can bind to lead, as well as the metals commonly used in electronic components,” explains Johnson. “That, say the researchers, could be a game-changer when recycling those metals. But the more valuable impact may be the ability to filter drinking water, starting with home faucets, and eventually scaling up to serve municipal water systems.” 

Writing for STAT, Prof. Kevin Esvelt explores how, “the immense potential benefits of biotechnology are profoundly vulnerable to misuse. A pandemic caused by a virus made from synthetic DNA — or even a lesser instance of synthetic bioterrorism — would not only generate a public health crisis but also trigger crippling restrictions on research.” Esvelt adds: “The world has too much to gain from the life sciences to continue letting just anyone obtain DNA sufficient to cause a pandemic.”
