Popular Science reporter Laura Baisas showcases an ingestible, berry-size thermometer developed by MIT researchers that could offer continuous monitoring for sick patients. The sensor “could make it easier to determine whether a patient is sick and if they’re at risk of developing a dangerously high fever. It can also help for people tracking their fertility or those under anesthesia," writes Baisas. "The team is now working on combining the temperature sensor with different sensors that could measure other vital signs such as heart rate." 

Scientific American reporter Clara Moskowitz spotlights a new study by Prof. Seth Lloyd that explores the feasibility of black holes sending information back in time. In the study, Lloyd and his colleagues calculate how much information can be sent backward via closed timelike curves, intensely bending, rotating space found around spinning black holes. “Spacetime can curve around so much that you can be innocently going forward in time and then you meet yourself in the past,” says Lloyd. 

Inside Precision Medicine spotlights Prof. Giovanni Traverso and his team’s work developing an oral drug formulation containing hydrogel that allows for the delivery of small molecules and antibodies via the esophageal mucosal lining. “We were interested in delivering anti-TNFs as a model drug, but also to help people who suffer from conditions like Crohn’s disease to have options that could be delivered to the site,” says Traverso. “If we have the possibility of site-directed delivery, we may be able to mitigate systemic side effects from these immunosuppressing agents.”

Associated Press reporter Rodrique Ngowi visits MIT to learn about how researchers in Prof. Xuanhe Zhao’s lab developed an ultrasound wristband that gathers data on human hand motions as part of an effort to help train humanoid robots to undertake complex tasks, from housework to surgery. “Imagine people doing housework,” says Zhao. “We can use the data obtained by our system to train a robot to do exactly (that) housework with this dexterous hand motion.” 

Using an ordinary fridge magnet to control a microrobot might sound like fiction, but a team of MIT researchers engineered a technique to 3D-print magnetically activated robots and other materials that could be used in medicine and more. MIT graduate students Andrew Chen and Rachel Sun joined Edgar B. Herwick III of GBH’s Curiosity Desk to discuss their work and inspiration. Sun explains that ultimately, they’re “trying to develop these materials for everyday uses that push the frontiers of what’s possible and how we can help people in society.” 

Manufacturing Dive reporter Cole Rosengren notes that a year after its launch, the MIT Initiative for New Manufacturing (INM) is “gaining traction toward its goal of helping modernize U.S. industrial systems.” Speaking at a Boston Tech Week event, Prof. John Hart, co-director of the INM, shared that at MIT, “we believe that there are important things we can do to help grow domestic manufacturing productivity, impart more sustainability in supply chains and industries, and also contribute to the creation of high-quality manufacturing jobs.”

The Economist reports on the growing popularity of ingestible sensors, including work at MIT where researchers are using the devices to “sense internal conditions and act on what they find.”  The MIT team “received $66m from ARPA-H, a federal grant system that pushes high-risk, transformative health-care technology, to develop ingestible devices for the oral delivery of mRNA treatments.” 

During a live interview in the GBH studios with Curiosity Desk host Edgar B. Herwick III, Research Scientist AJ Perez shares his work developing a new method to reuse recycled plastic to 3D print construction-grade materials for home building, which could help reduce home construction costs. “This all started with the idea of trying to build the roughly one billion homes the world needs,” says Perez. 

In an effort to defend medical devices against quantum attacks, MIT researchers have engineered an ultra-efficient microchip that can protect wireless biomedical devices, such as insulin pumps and pacemakers, reports Katie Hunt for CNN. The microchip, which is around the size of an extremely fine needle tip, “includes built-in protection needed for post-quantum cybersecurity. The device achieved between 20 and 60 times higher energy efficiency than other post-quantum security techniques.”

New York Times reporter Melissa Kirsch spotlights a study by MIT scientists that explores how the “sound of rain causes some seeds to germinate faster.”

A new tool developed by MIT researchers could help violin designers test how an instrument might sound when certain dimensions or properties are changed without even pulling out a bow, reports Jennifer Ouellette for Ars Technica. The researchers crafted a virtual violin, “a computer simulation tool that can capture the precise physics of the instrument and even reproduce a realistic sound of a plucked string,” Ouellette explains. 

Cambridge Day reporter Zoe Beketova, a student in MIT’s Graduate Program in Science Writing, visits Prof. Xuanhe Zhao’s lab to get a hands-on look at the group’s ultrasound wristband that can map movements of the human body using sound waves, part of the group’s work aimed at changing “how we gather information from inside the body.” Says Zhao: “The mission of my lab is really merging humans with machines and AI. We believe there’s a huge opportunity [with] this interface.”

Forbes contributor Michael T. Nietzel spotlights the 120 new members and 25 international members elected by the National Academy of Sciences for 2026. Several MIT faculty members – including Professors Michale Fee, Gareth McKinley, Keith Nelson, Bengt Holmstrom and Catherine Wolfram – were selected. 

Prof. Xuanhe Zhao speaks with Tech Briefs reporter Andrew Corselli about his team’s work developing an ultrasound wristband that precisely tracks a wearer’s hand movements in real time and can communicate device these motions to a robot or a virtual environment. “For the future of human society, humanized robots will do lots of different work for us. For that work, we need a dexterous robotic hand,” explains Zhao. “We believe this ultrasound wristband, based on variable imaging, could be the future of really knowing the human hand motions.”

Prof. Anette “Peko” Hosoi and Andy Harland of Loughborough University lace up their shoes to chat about how runners can optimize their marathon performance with Edgar B. Herwick III of GBH’s Curiosity Desk.  The Boston Marathon “is an iconic race and it is challenging for a lot of different reasons,” Hosoi notes. “Boston starts on a downhill, so you feel great…but if you are not managing your energy by the time you get to Heartbreak Hill at mile 20 you are going to be suffering.”
