Researchers from MIT and elsewhere have developed a new AI technique for teaching robots to pack items into a limited space while adhering to a range of constraints, reports Nick Hilden for Scientific American. “We want to have a learning-based method to solve constraints quickly because learning-based [AI] will solve faster, compared to traditional methods,” says graduate student Zhutian “Skye” Yang.
Researchers from MIT and elsewhere have developed a new 3D printing process that “allows users to create more elastic materials along with rigid ones using slow-curing polymers,” reports Tony Ho Tran for the Daily Beast. The researchers used the system to create a, “3D printed hand complete with bones, ligaments, and tendons. The new process also utilizes a laser sensor array developed by researchers at MIT that allows the printer to actually ‘see’ what it’s creating as it creates it.”
Writing for the Financial Times, Prof. Carlo Ratti explores the concept of the “15-minute city,” which is aimed at creating walkable neighborhoods. “The 15-minute city must be paired with investment in transport between neighborhoods,” writes Ratti, noting that investment is especially needed in public transportation to ensure that 15-minute cities do not contribute to greater segregation.
Science News reporter James Riordon writes that by employing a new technology called frequency-dependent squeezing, LIGO detectors should now be able to identify about 60 more mergers between massive objects like black holes and neutron stars than before the upgrade. Senior research scientist Lisa Barsotti, who oversaw the development of this new technology, notes that even next-generation gravitational wave detectors will be able to benefit from quantum squeezing. “The beauty is you can do both. You can push the limit of what is possible from the technology of laser power and mirror [design],” Barsotti explains, “and then do squeezing on top of that.”
Researchers from MIT and Harvard have found that an adult’s ability to “parse the early attempts of children to talk may also help the children learn how to speak properly faster,” reports Jess Thomson for Newsweek. “These adult listening abilities might help children communicate very early and highlight that speech is a good way to share information with others," says postdoctoral associate Stephan Meylan. "That said, there is a lot of diversity in how adults and children interact across the world, both within and across different social and cultural contexts. This means that there are very likely many pathways to understanding language."
MIT researchers Lisa Barsotti, Deep Chatterjee and Victoria Xu speak with Curiosity Stream about how developments in gravitational wave detection are enabling a better understanding of the universe. Barsotti notes that in the future, gravitational wave science should help enable us to, “learn more about dark matter about primordial black holds to try to solve some of the biggest mysteries in our universe.” Xu notes, “the detection of gravitational waves is a completely new window that has opened into our universe.”
The Center for UltraCold Atoms, located at MIT, is one of four university physics programs that will share $76 million in funding from the National Science Foundation as part of the organization’s Physics Frontiers Centers program, which aims to “foster major breakthroughs at the intellectual frontiers of physics,” writes Michael T. Nietzel for Forbes. “[T]he Center for UltraCold Atoms is a joint effort with Harvard University that will explore how to achieve greater control and programmability of complex quantum systems,” he explains.
Popular Science reporter Andrew Paul writes that MIT researchers have developed a new long-range, low-power underwater communication system. Installing underwater communication networks “could help continuously measure a variety of oceanic datasets such as pressure, CO2, and temperature to refine climate change modeling,” writes Paul, “as well as analyze the efficacy of certain carbon capture technologies.”
Prof. Scott Stern co-leads the Place-Based Innovation Policy Study Group – “a group of academics, practitioners and NSF staff that aims to deploy ‘timely insight for the NSF Regional Innovation Engines program,’” reports Nature. Stern and his colleagues are “providing an assessment of the ‘state of knowledge’ of place-based innovation ecosystems and their relationship to geographical and socio-economic inclusion,” writes Nature.
MIT scientists have developed a new brain “atlas” and computer model that sheds insight into the brain-body connections in C. elegans worms, reports Lauren Leffer for Scientific American. “Through establishing those brain-behavior links in a humble roundworm,” writes Leffer, “neuroscientists are one step closer to understanding how all sorts of animal brains, even potentially human ones, encode action.”
MIT researchers have developed a new tool called “PhotoGuard” that can help protect images from AI manipulation, reports Ross Cristantiello for Boston.com. The tool “is designed to make real images resistant to advanced models that can generate new images, such as DALL-E and Midjourney,” writes Cristantiello.
Researchers at MIT have developed “PhotoGuard,” a tool that can be used to protect images from AI manipulation, reports Catherine Thorbecke for CNN. The tool “puts an invisible ‘immunization’ over images that stops AI models from being able to manipulate the picture,” writes Thorbecke.
MIT researchers at MIT have developed a microfluidic chip-based model of liver tissue that “allows researchers to understand the biological mechanisms underlying liver tissue regeneration and points to several molecules that may promote the process,” reports William A. Haseltine for Forbes. "These results mark significant progress in our understanding of the human body’s regenerative properties," writes Haseltine.
Researchers at MIT have developed a wearable patch that can allow drugs to pass through the skin using ultrasonic sound waves, reports Sandra Tsing for NPR. “The researchers say their lightweight design allows for reliable use on the go,” says Tsing. “This could treat skin conditions, both medical or cosmetic.”
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.”
