Researchers have made a significant advance in spectral geometry by proving a special case of Pólya’s conjecture related to the eigenvalues of a disk. Their work, blending theoretical elegance with potential practical applications, highlights the universal value and artistic beauty of mathematical research.

Credit: Inventiones mathematicae (2023). DOI: 10.1007/s00222-023-01198-1 Is it possible to deduce the shape of a drum from the sounds it makes? This is the kind of question that Iosif Polterovich, a professor in the Department of Mathematics and Statistics at Université de Montréal, likes to ask. Polterovich uses spectral geometry, a branch of mathematics, to understand physical phenomena involving wave propagation.…

As well as everything else, this wonderfully sweet and funny film will contribute to the debate about whether repressive regimes are the nursery of artistic greatness. The Iranian government has prevented the film’s two directors, Maryam Moghaddam and Behtash Sanaeeha, from travelling to Berlin to attend their own premiere; six months ago, their production offices were raided and computers and hard drives confiscated. But, fortunately, the police couldn’t find the film itself, whose gentle humanity is a compelling rebuke…

The most thorough study yet of a mysterious creature that lived 300 million years ago has ruled that it had no bones after all.Since its discovery nearly 70 years ago, the true nature of Tullimonstrum gregarium – AKA the Tully monster – has confounded scientists. Studies have variously found it was a vertebrate, or an invertebrate, with a back-and-forth that has gone on for years."We believe that the mystery of it being an invertebrate or vertebrate has been solved," says paleontologist Tomoyuki Mikami, at the University…

An illustration depicts a study by SLAC and Stanford, including cryo-EM imaging (left), that discovered how a cellular machine called TRiC (right) directs the folding of tubulin (yellow tangle at the center of TRiC). Tubulin is the protein building block of microtubules that serve as the scaffolding and transport system in human cells.

After 70 years of ownership, the DiPietro family is stepping away from Edgewater Inn. And the owners of Local 46 are stepping in. Niya and Grant Gingerich are under contract to purchase the longtime pizza parlor and bar from Carolyn DiPietro and her daughter Haley, who have run it since 2012. Carolyn’s parents, Josephine and Ben DiPietro founded “the Edge” in 1953 at 5302 W. 25th Ave. in Edgewater. “We couldn’t think of a better way to serve the community again than taking over this long-standing, beloved place and being…

Image via Warner Bros. Pictures The audiences of HBO Max have turned their backs on the only live-action DC Comics superhero film to be released this year, Matt Reeves’ The Batman. Instead, they have turned their attention to a heartwarming comedy from 2015. The film is The Intern, which was written and directed by Nancy Meyers, who also wrote The Holiday, Father of the Bride, and The Parent Trap. Starring Anne Hathaway and Robert De Niro, the film follows Ben (De Niro), a retired business executive who takes…

In 2015, South Korea’s Samsung Electronics Co. jolted the technology world with news that its chips were on par with the world’s most advanced. This summer, the Chinese company Semiconductor Manufacturing International Corp. is drawing buzz in the same circles after word emerged that it, too, has made a big jump. One man links the two events, an engineer legendary in chip-industry circles and barely known outside them: Liang Mong Song.…
