New Scientist’s Jacklin Kwan highlights Prof. Christoph Kehle’s work demonstrating that extremal black holes, a variety of black hole that has zero temperature, could exist. “Extremal black holes were thought of as an idealised, unattainable limit: something you could write down as a solution, but which could never be reached [through any real physical] process, but we proved that wrong,” says Kehle.
Prof. Joshua Tenenbaum discusses whether AI systems will perform better if they have increased awareness of the world around them with New Scientist’s Daniel Cossins. “One of the big misconceptions is that intelligence is a single thing, that there is a single world model in the brain,” says Tenenbaum. “What we actually have is the ability to run many different models depending on the context, task and goal.”
Bob Mumgaard PhD ‘15, co-founder and CEO of MIT spinout Commonwealth Fusion Systems, speaks to Fast Company’s Adele Peters about building his company’s first power plant, set to come online in the 2030s in Virginia. “To make fusion into more than just the first plants, it has to be an industry and there’s multiple parts of that,” says Mumgaard.
Prof. Jackson Lu speaks to Fast Company’s Sarah Bregel about metacognitive techniques, tuning into one’s thinking and learning process, to use AI more creatively. “Even the most powerful AI won’t boost creativity if employees don’t know how to use it effectively,” says Lu. “Organizations should pair AI deployment with metacognition training to maximize the creative benefits.”
Prof. Richard Binzel discusses Apophis, an asteroid roughly 340-meters in diameter, set to pass within 32,000 kilometers of Earth on April 13, 2029 with Scientific American’s Andrew Jones. Apophis’s close approach in 2029 will offer “a once-per-millennium natural experiment,” says Binzel.
President Sally Kornbluth joins Jim Braude and Margery Eagan, hosts of GBH’s Boston Public Radio, for a live conversation about the unique value of university research, the impacts of immigration policy on international students and the nation’s talent pipeline, and MIT’s commitment to ensuring the nation remains a leader in science and innovation. “You're not going to see an effect immediately. What's going to happen is five years, 10 years, 20 years down the line, you're going to see a pipeline that's not full anymore—a pipeline of talent, a pipeline of basic discoveries,” says Kornbluth.
MIT researchers have designed a recyclable elastic yarn, made from polyethylene, that mimics the stretchiness of spandex-polyester and spandex-nylon blends, the Anthropocene team writes. “[T]he researchers spun a spool of yarn, melted it, and re-spun it into new yarn several times. Even after 10 cycles, the yarn was as strong and flexible as conventional blended fibers,” explains Anthropocene.
MIT researchers have developed a new, breathable hydrogel material that is “packed with microscopic air tunnels inspired by the way human lungs move oxygen” and allows heat and sweat to escape, reports Luis Prada for VICE. “The material proved to be about 10 times more breathable than conventional hydrogels and retained about 95 percent of its airflow even after being stretched 10,000 times,” explains Prada.
MIT researchers have developed a low temperature process to extract battery-grade lithium from spodumene, the most common type of mineral containing lithium, using a reusable liquid reagent, writes Electronic Design’s Lee Goldberg. “The new process uses a liquid reagent to dissolve the rock into the useful forms of its constituent parts — not just battery-ready lithium salts, but also smelter-grade alumina and cement-ready silica,” writes Goldberg. “After the minerals are extracted, the solvent and reagent can be recovered and used again so that waste levels approach zero.”
Smithsonian Magazine reporter Margherita Bassi highlights a new robot developed by Prof. Raphael Zufferey that mimics aquatic birds’ ability to fly and swim underwater. “Our dream vision is for oceanographers, marine biologists and members of coastal communities to launch this robot from a boat or from shore, and it would fly close to the area of interest, such as an iceberg or a port facility or over a pod of whales,” Zufferey says. “It would dive into the water to take a measurement or collect a sample and fly back to deliver the data at a fraction of the cost of traditional methods.”
In a new study by MIT FutureTech, 272 researchers ranked the top 24 AI risks, write Axios reporters Jim VandeHei and Mike Allen. The researchers “assessed a 12% chance that AI's dangerous capabilities produce a catastrophic outcome by 2030, and another 12% chance of AI-enabled weapons and mass-harm capabilities [with mitigation efforts to reduce risk],” VandeHei and Allen explain.
Researchers from MIT and Toyota Research Institute developed SceneSmith, a system that allows robots to practice everyday tasks and action plans in over 1,300 AI generated environments before entering a real home or workplace, writes Fox News’ Kurt Knutsson. “SceneSmith's ability to combine realistic design with usable physics gives the project its strongest advantage,” notes Knutsson.
Prof. Daniela Rus, director of CSAIL, joins Hakeem Oluseyi, host of GBH’s “Particles of Thought,” to discuss the lab’s work utilizing AI to enhance robots’ ability to move, reason, and act like humans. “The objective is to bring AI’s ability to understand text, images, and other online information to make physical machines intelligent, and if we achieve this then AI will not just reside in our computers—it will drive, it will walk it will fly, it will interact with us in the physical world.”
Graduate student Peter Zhi Xuan Li speaks to Tech Briefs’ Andrew Corselli about his team’s work developing a new chip that allows small, autonomous robots and other battery-limited devices to construct detailed 3D maps of their environments using a fraction of the power required by other systems. “Today, a robot uses separate, incompatible internal representations for different jobs: one for mapping, another for tracking its own motion, another for rendering what it sees, and every conversion adds memory footprint and energy,” says Li. “Our goal is a single shared representation.”
By studying ‘smears’ in fast radio bursts, fleeting flashes of radiation, MIT researchers discovered diffuse clouds of baryonic gas may contain the missing ordinary matter in the universe, writes Gizmodo’s Gayoung Lee. “These diffuse clouds may be flung outside galaxies through black hole jets,” Lee explains.
