Innovation

Owl-Inspired Aerogel

Modern life is full of noise—from honking traffic to roaring machinery—but nature may already hold the answer: owls. Known for their silent flight, owls owe their stealth to feather structures and soft skin that absorb both high- and low-frequency sounds. Inspired by this, researchers at China’s Tiangong University created a two-layer aerogel that mimics owl anatomy. The material absorbed 58% of incoming sound waves, outperforming many conventional noise control technologies. “This study paves the way for high-performance, lightweight, and durable sound-absorbing materials that can significantly alleviate noise pollution from industrial equipment and traffic,” the researchers said in a press release.

The innovation goes beyond previous owl-inspired designs, which mostly influenced the shape of airfoils in planes, cars, drones, and turbines. This new aerogel replicates the structure of owl feathers and skin. Its two layers serve distinct purposes: a porous base layer, built using a honeycomb structure formed by freeze-reconstructed hexane droplets, mimics owl skin and absorbs low-frequency rumbles. On top, a feather-like layer of silicon nanofibers blocks higher-frequency noise—solving a major limitation of standard soundproofing materials, which typically address only one part of the frequency spectrum and require stacking for full coverage.

Lightweight yet durable, the owl-inspired aerogel held up through 100 compression cycles with minimal wear and successfully reduced engine noise from 87.5 decibels to 78.6 decibels. That’s better than many of today’s top-tier noise-dampening products. With potential applications in cars, factories, and other industrial settings, the material offers a smart alternative where eliminating noise at the source isn’t feasible. And with noise pollution linked to serious health risks—like permanent hearing loss, cardiovascular disease, and even type 2 diabetes—this kind of innovation could make a meaningful impact.

Loft Find Nets $625K

A rare collection of scientific papers by WWII codebreaker and computing pioneer Alan Turing has sold for over half a million dollars—after nearly being shredded in a London attic. The archive, which included personal letters and academic works, was discovered in a home once owned by Turing’s close friend, mathematician Norman Routledge. “There were lots of personal papers which one sister carted away and stored in her loft,” recalled one of Routledge’s nieces. The papers sat untouched for nearly a decade, until a family member recognized their importance during a house clean-out. “Her daughters came across the papers and considered shredding everything… One of the cousins felt the Turing papers might be of interest to collectors.”

The auction’s centerpiece was Turing’s signed copy of his 1938 PhD dissertation, Systems of Logic Based on Ordinals, which sold for $150,000. Even more sought-after was his 1936 paper On Computable Numbers—known as “Turing’s Proof”—which introduced the concept of a universal computing machine. It sold for $280,000, nearly five times the estimate. Auctioneer Charles Hanson described the items as “some of the most important” he’s ever handled. “To think these precious papers could’ve been lost to the shredder—and now they will go on to educate and inspire generations,” Hanson said. “Turing was a man ahead of his time, and through these pages, he lives on.”

Printed in small academic runs and gifted by Turing’s mother to Routledge, the documents—called “offprints”—are considered extremely rare. Their rediscovery is a poignant reminder of Turing’s brilliance and complex legacy. Despite helping win the war by cracking the Nazi Enigma code, Turing was prosecuted in 1952 for being gay and died two years later at age 41. He was posthumously pardoned in 2011, and his story gained renewed attention with The Imitation Game in 2014. “Alan Turing changed the world through his ideas,” said Hanson. “It’s a once-in-a-lifetime discovery—not just for collectors, but for the sake of preserving the story of one of the greatest minds in history.”

History

Vintage Photo Manipulation

A pioneer who helped elevate photography to an art form is finally receiving renewed recognition—170 years after opening his first studio. Henry Peach Robinson, born in 1830 in Ludlow, Shropshire, began his career studying painting and drawing while working in a Leamington Spa bookshop. He opened his portrait studio there in 1855 and quickly became known for his innovative technique of combination printing, where multiple negatives were merged to create a single, detailed image. "He really showed photographers at that time that photography could be art," said photographic historian Dr. Michael Pritchard.

By 1857, Robinson was already winning medals for his art photography—a career that continued to flourish through the 1890s. His most famous image, Fading Away, used five negatives to depict a dying girl surrounded by her family. The emotionally charged work, now held at the Metropolitan Museum of Art in New York, even caught the attention of Prince Albert. “It’s something we do today in Photoshop relatively easily,” said Pritchard, “but in the late 1850s and mid-19th Century it was a pretty groundbreaking technique.” Robinson's influence extended beyond the darkroom—he was a founding member of the Birmingham Photographic Society and authored several books.

Now, Leamington Spa is honoring Robinson’s legacy. The local photographic society is highlighting his contributions, with a local history group featuring him in a new book. To mark the anniversary, the society hosted an event with celebrity photographer Rankin, drawing more than 150 attendees. “That link about the world's top portrait photographer of the 1800s living and working in Leamington Spa and we got the world's top portrait photographer of current times actually coming to the town—that binds the whole story together,” said outgoing vice chair Mark Godfrey. As Pritchard noted, “He was entrepreneurial, he was commercial, but at the same time he was artistic and he was promoting photography as an art form.”
