Prof. Jesús del Alamo speaks with Ira Flatow of NPR’s Science Friday about the importance of the CHIPS Act and the pressing need to invest in semiconductor manufacturing in the U.S. “There is a deep connection between leading-edge manufacturing and innovation,” says del Alamo. “Whoever gets the most advanced technology first in the marketplace is going to rip off the greatest profits, and as a result is going to be able to invest into innovation at a greater level and therefore be able to move faster than their competitors.”

Prof. Jesús del Alamo speaks with Ann Fisher of WOSU’s All Sides with Ann Fisher about the importance of supporting domestic chip manufacturing in the U.S., and the need to help encourage students to pursue careers in the semiconductor industry. “Universities and colleges train over 50% of the semiconductor workforce,” says del Alamo, “and so investing in education, investing in the infrastructure, both human but also physical infrastructure that supports education and research, is really critical in the long run.” 

MIT researchers have created a thin, lightweight and flexible loudspeaker that is as thin as a few sheets of paper and can stick to most surfaces while producing high quality sound, reports Kendra Redmond for Science News Explores. “Because the design is so flexible and durable, companies could potentially integrate speakers into T-shirts or other personal items,” writes Redmond. “Or users could make their own.”

Ross Trethewey, co-host of This Old House, visits Prof. Vladimir Bulović, director of MIT.nano, to learn more about the future of solar technology, including an electricity-generating film that can be applied to windows and other materials. “Dramatic advancements are on the horizon,” says Bulović. “We can make solar cells that don’t weigh very much at all so deployment of them on top of your roof could be as simple as unrolling a carpet and stapling it to the roof with a plug. Maybe your windows will be turned into solar cells.” 

TechCrunch reporter Brian Heater spotlights multiple MIT research projects, including MIT Space Exploration Initiative’s TESSERAE, CSAIL’s Robocraft and the recent development of miniature flying robotic drones.

MIT engineers have created insect-sized robots that can emit light when they fly and could eventually be used to aid search-and-rescue missions, reports WHDH. “Our idea is, if we can send in hundreds or thousands of those tiny flying robots then once they find that survivor, they will shine out light and pass information back and signal people on the outside saying ‘we found someone who’s trapped,'” explains Prof. Kevin Chen.

MIT engineers have developed tiny flying robots that can light up, reports Colleen Hagerty for Popular Science. “If you think of large-scale robots, they can communicate using a lot of different tools—Bluetooth, wireless, all those sorts of things,” says Prof. Kevin Chen. “But for a tiny, power-constrained robot, we are forced to think about new modes of communication.”

MIT researchers have developed a flexible and paper-thin speaker that can turn any surface into an audio source, reports New Scientist. “The lightweight loudspeaker uses only a fraction of the energy of a regular speaker and can generate sound regardless of the surface it is attached to,” writes New Scientist.

A time capsule buried in 1957 by former MIT President James R. Killian and Prof. Harold Edgerton will be unveiled in 2957 a full millennium after its burial, writes Michele Debczak for Salon.

Researchers at MIT have built a highly efficient thermophotovoltaic cell that converts incoming photons to electricity, reports Kevin Hurler for Gizmodo. “We developed this technology—thermal batteries—because storing energy as heat rather than storing it electrochemically is 10 to 100 times cheaper," explains Prof. Asegun Henry. 

MIT researchers have developed a new ultrathin material that can turn any rigid surface into a speaker, reports Haje Jan Kamps for TechCrunch. “The loudspeaker could be used in active noise cancellation, for example — combine the speaker tech with some electronics and microphones, and it could cancel out sound,” writes Kamps. “The inventors also envision immersive sound experiences, and other low-energy use cases such as smart devices, etc.”

Daily Beast reporter Tony Ho Tran writes that MIT researchers have created a new loudspeaker that is as thin as paper and produces high-quality sound. The paper-thin device “weighs roughly the same as a dime, and can be used to cover surfaces like walls and ceilings,” writes Tran. “The loudspeaker also uses a fraction of the energy a typical speaker requires, while producing comparable sound quality.”

MIT researchers have developed an ultrathin speaker that can be applied to surfaces like wallpaper, reports Andrew Liszewski for Gizmodo. “The applications for the thin-film speaker material are endless,” writes Liszewski. “In addition to being applied to interiors like office walls or even the inside of an airplane to cancel out unwanted noises, an entire car could be wrapped in a speaker, making it easier to alert pedestrians that an otherwise silent electric vehicle was approaching.”

Researchers at MIT have created a 3D-printable Oreometer that uses twisting force to determine if it is possible to evenly split an Oreo cookie, reports Juandre for Popular Mechanics. “While studying the twisting motion, the engineers also discovered the torque required to successfully open an Oreo is about the same as what’s needed to turn a doorknob—a tenth of the torque required to open a bottle cap,” writes Juandre.

A group of MIT scientists led by PhD candidate Crystal Owens has developed an Oreometer, a device used to determine if it is possible to evenly split an Oreo cookie every time, reports Maria Jimenez Moya for USA Today. “One day, just doing experiments, and, all of a sudden we realized that this machine would be perfect for opening Oreos because it already has … the fluid in the center, and then these two discs are like the same geometry as an Oreo,” says Owens.
