Researchers unexpectedly discovered toxic airborne pollutants in Oklahoma. The image above depicts a field in Oklahoma. Credit: Shutterstock University of Colorado Boulder researchers made the first-ever airborne detection of Medium Chain Chlorinated Paraffins (MCCPs) in the Western Hemisphere. Sometimes, scientific research feels a lot like solving a mystery. Scientists head into the field with a clear goal and a solid hypothesis, but then the data reveals something surprising. That’s when the real detective work begins. This is exactly what happened to a team from the University of Colorado Boulder during a recent field study in rural Oklahoma. They were using a state-of-the-art instrument to track how tiny particles form and grow in the air. But instead of just collecting expected data, they uncovered something completely new: the first-ever airborne detection of Medium Chain Chlorinated Paraffins (MCCPs), a kind of toxic organic pollutant, in the Western Hemisphere. The teams findings were published in ACS Environmental Au. “It’s very exciting as a scientist to find something unexpected like this that we weren’t looking for,” said Daniel Katz, CU Boulder chemistry PhD student and lead author of the study. “We’re starting to learn more about this toxic, organic pollutant that we know is out there, and which we need to understand better.” MCCPs are currently under consideration for regulation by the Stockholm Convention, a global treaty to protect human health from long-standing and widespread chemicals. While the toxic pollutants have been measured in Antarctica and Asia, researchers haven’t been sure how to document them in the Western Hemisphere’s atmosphere until now. From Wastewater to Farmlands MCCPs are used in fluids for metal working and in the construction of PVC and textiles. They are often found in wastewater and as a result, can end up in biosolid fertilizer, also called sewage sludge, which is created when liquid is removed from wastewater in a treatment plant. In Oklahoma, researchers suspect the MCCPs they identified came from biosolid fertilizer in the fields near where they set up their instrument. “When sewage sludges are spread across the fields, those toxic compounds could be released into the air,” Katz said. “We can’t show directly that that’s happening, but we think it’s a reasonable way that they could be winding up in the air. Sewage sludge fertilizers have been shown to release similar compounds.” MCCPs little cousins, Short Chain Chlorinated Paraffins (SCCPs), are currently regulated by the Stockholm Convention, and since 2009, by the EPA here in the United States. Regulation came after studies found the toxic pollutants, which travel far and last a long time in the atmosphere, were harmful to human health. But researchers hypothesize that the regulation of SCCPs may have increased MCCPs in the environment. “We always have these unintended consequences of regulation, where you regulate something, and then there’s still a need for the products that those were in,” said Ellie Browne, CU Boulder chemistry professor, CIRES Fellow, and co-author of the study. “So they get replaced by something.” Measurement of aerosols led to a new and surprising discovery Using a nitrate chemical ionization mass spectrometer, which allows scientists to identify chemical compounds in the air, the team measured air at the agricultural site 24 hours a day for one month. As Katz cataloged the data, he documented the different isotopic patterns in the compounds. The compounds measured by the team had distinct patterns, and he noticed new patterns that he immediately identified as different from the known chemical compounds. With some additional research, he identified them as chlorinated paraffins found in MCCPs. Katz says the makeup of MCCPs are similar to PFAS, long-lasting toxic chemicals that break down slowly over time. Known as “forever chemicals,” their presence in soils recently led the Oklahoma Senate to ban biosolid fertilizer. Now that researchers know how to measure MCCPs, the next step might be to measure the pollutants at different times throughout the year to understand how levels change each season. Many unknowns surrounding MCCPs remain, and there’s much more to learn about their environmental impacts. “We identified them, but we still don’t know exactly what they do when they are in the atmosphere, and they need to be investigated further,” Katz said. “I think it’s important that we continue to have governmental agencies that are capable of evaluating the science and regulating these chemicals as necessary for public health and safety.” Reference: “Real-Time Measurements of Gas-Phase Medium-Chain Chlorinated Paraffins Reveal Daily Changes in Gas-Particle Partitioning Controlled by Ambient Temperature” by Daniel John Katz, Bri Dobson, Mitchell Alton, Harald Stark, Douglas R.

The 17th-century frescoes and antique mirrors should immediately tip visitors off: This showroom has something it needs to say. Palazzo Durini Caproni di Taliedo is a historic building in Milan, designed and built in the mid-1600s by Baroque architect Francesco Maria Richini. Among many other monumental works and churches, he also designed Milan’s Palazzo di Brera, which currently includes the Pinacoteca di Brera museum. The Palazzo Durini Caproni di Taliedo was commissioned by the heir to the Durinis, a wealthy merchant family.Today the palazzo is furniture showroom as palimpsest. Since 2021, Edra has exhibited collaborations with supremely contemporary designers, including the Campana brothers, Jacopo Foggini, and Francesco Binfaré, amid the restored Baroque grandeur.Courtesy Edra.Palazzo Durini in the 1920s, when the famed Italian aircraft designer and aeronautical engineer Giovanni Battista Caproni used it as an office.Walking through the rooms, one might imagine the visitors who could have lounged on an Edra “On the Rocks” sofa at one time or another in the history of this place: Giovanni Battista Caproni, the Italian count and aeronautical engineer who lived and worked in the building for more than 40 years? Soccer sensation Ronaldo, who caused a near riot when he visited the palazzo during its Inter Football Club era, when the sports association’s offices were located here?

Microsoft accidentally replaced Windows 11 startup sound with one from Vista Taras Buria Neowin @TarasBuria · Jun 14, 2025 14:46 EDT The recently released Windows 11 Dev and Beta builds introduced some welcome changes and improvements. However, those preview builds are not flawless and have a pretty long list of known issues. One of those issues, though, is a rather delightful one: Windows 11's default startup jingle has been accidentally replaced with one from 2006. After Windows Insiders discovered that Windows 11 now plays the Windows Vista startup sound and reported it to Microsoft, the company acknowledged it and added it to the list of known bugs in the latest Windows 11 Dev and Beta builds: This week’s flight comes with a delightful blast from the past and will play the Windows Vista boot sound instead of the Windows 11 boot sound. We’re working on a fix. Although Windows Vista is nearly two decades old, it was brought to everyone's attention this week after Apple introduced macOS 26 Tahoe with its controversial "Liquid Glass" redesign, which many consider a rather miserable remix of Windows Aero from Windows Vista and Windows 7. While it is definitely an interesting coincidence, Microsoft did not intentionally replace the startup sound in Windows 11 preview builds. Brandon LeBlanc from the Windows Insider team confirmed in his X that that is a bug after joking about everyone talking about Windows Vista once again in light of Apple's latest announcements: It is worth noting that if you miss the startup sound of Windows Vista, you can still use it in modern Windows versions. All it takes is the original WAV file and a few clicks in the Windows Registry and Sound settings. And for those who want a shot of nostalgia, here is the sound of Windows Vista startup: What startup jingle do you like more: Windows Vista or Windows 11? Share your thoughts in the comments.

In a nutshell: The OS updates coming to Apple devices later this year will institute the company's first major UI design shift in over a decade, but eagle-eyed observers noticed similarities with an old version of Windows – comparisons that haven't escaped Microsoft's notice. Thankfully, users concerned about Apple's upcoming interface will have options to change its visual presentation. Some of Microsoft's social media accounts recently poked fun at the upcoming "Liquid Glass" user interface design language Apple unveiled at WWDC this week. Although the Cupertino giant has hailed the update as a major innovation, many immediately began comparing it to Microsoft's nearly two-decade-old Windows Vista UI.         View this post on Instagram                       A post shared by Windows (@windows) Liquid Glass is Apple's name for the new visual style arriving in iOS 26, iPadOS 26, macOS 26 Tahoe, watchOS 26, and tvOS 26, which will launch this fall. Inspired by the Apple Vision Pro's visionOS, the design language favors rounded edges and transparent backgrounds for inputs and other UI functions. It is Apple's most significant design change since iOS 7 debuted almost 12 years ago, and the first to establish a unified language across all of the company's devices. On the left: nice Liquid Glass UI minimalistic look. On the right: Liquid Glass looking all kinds of wrong in the current beta. Apps, wallpapers, and other background content will be visible through app icons, notifications, and menu elements for a glass-like appearance. Apple claims that the effect will improve cohesion across the interface, but beta testers are concerned that text will become less readable. Others, including Microsoft, mocked the update's resemblance to Windows Vista's glass-like "Aero" aesthetic, which debuted in 2007. That OS also made UI elements partially transparent, but Microsoft eventually phased it out when it began moving toward its current design language. The official Windows Instagram account recently responded to Apple's presentation by posting a slideshow of Vista screenshots played over a nostalgic Windows boot tune. The Windows Twitter account also shared a picture recalling the Vista-era profile icons. Other social media users joined in on the fun. Some highlighted the unfortunate placement of the YouTube icon in Apple's Liquid Glass explainer video, which the company altered. Others compared the design language to the unique chassis for Apple's 2000 Power Mac G4 Cube and the main menu for Nintendo's 2012 Wii U game console. Fortunately, users can customize Liquid Glass by switching between transparent, light, and dark modes. They can also opt for a slightly more opaque presentation with a toggle located under Settings > Accessibility > Display & Text Size > Reduce Transparency.

Global sportswear leader Nike is reportedly preparing to release the Air Max 1000 Oatmeal, its first fully 3D printed sneaker, with a launch tentatively scheduled for Summer 2025. While Nike has yet to confirm an official release date, industry sources suggest the debut may occur sometime between June and August. The retail price is expected to be approximately $210. This model marks a step in Nike’s exploration of additive manufacturing (AM), enabled through a collaboration with Zellerfeld, a German startup known for its work in fully 3D printed footwear. Building Buzz Online The “Oatmeal” colorway—a neutral blend of soft beige tones—has already attracted attention on social platforms like TikTok, Instagram, and X. In April, content creator Janelle C. Shuttlesworth described the shoes as “light as air” in a video preview. Sneaker-focused accounts such as JustFreshKicks and TikTok user @shoehefner5 have also offered early walkthroughs. Among fans, the nickname “Foamy Oat” has started to catch on. Nike’s 3D printed Air Max 1000 Oatmeal. Photo via Janelle C. Shuttlesworth. Before generating buzz online, the sneaker made a public appearance at ComplexCon Las Vegas in November 2024. There, its laceless, sculptural silhouette and smooth, seamless texture stood out—merging futuristic design with signature Air Max elements, such as the visible heel air unit. Reimagining the Air Max Legacy Drawing inspiration from the original Air Max 1 (1987), the Air Max 1000 retains the iconic air cushion in the heel while reinventing the rest of the structure using 3D printing. The shoe’s upper and outsole are formed as a single, continuous piece, produced from ZellerFoam, a proprietary flexible material developed by Zellerfeld. Zellerfeld’s fused filament fabrication (FFF) process enables varied material densities throughout the shoe—resulting in a firm, supportive sole paired with a lightweight, breathable upper. The laceless, slip-on design prioritizes ease of wear while reinforcing a sleek, minimalist aesthetic. Nike’s Chief Innovation Officer, John Hoke, emphasized the broader impact of the design, noting that the Air Max 1000 “opens up new creative possibilities” and achieves levels of precision and contouring not possible with traditional footwear manufacturing. He also pointed to the sustainability benefits of AM, which produces minimal waste by fabricating only the necessary components. Expansion of 3D Printed Footwear Technology The Air Max 1000 joins a growing lineup of 3D printed footwear innovations from major brands. Gucci, the Italian luxury brand known for blending traditional craftsmanship with modern techniques, unveiled several Cub3d sneakers as part of its Spring Summer 2025 (SS25) collection. The brand developed Demetra, a material made from at least 70% plant-based ingredients, including viscose, wood pulp, and bio-based polyurethane. The bi-material sole combines an EVA-filled interior for cushioning and a TPU exterior, featuring an Interlocking G pattern that creates a 3D effect. Elsewhere, Syntilay, a footwear company combining artificial intelligence with 3D printing, launched a range of custom-fit slides. These slides are designed using AI-generated 3D models, starting with sketch-based concepts that are refined through AI platforms and then transformed into digital 3D designs. The company offers sizing adjustments based on smartphone foot scans, which are integrated into the manufacturing process.

html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "http://www.w3.org/TR/REC-html40/loose.dtd" Japanese architect Shigeru Ban has created the Blue Ocean Dome (BOD) for the Osaka-Kansai Expo 2025, addressing the urgent issue of marine plastic pollution and raising crucial awareness about it.Named Blue Ocean Dome, the pavilion stands out with its innovative design, comprising three distinct dome types: Dome A, Dome B, and Dome C. Each dome is specifically crafted to host captivating installations and dynamic exhibitions, promising an unforgettable experience for all visitors throughout the event. Image © Taiki FukaoThe project was commissioned by the Zero Emissions Research and Initiatives (ZERI), a global network of creative minds, seeking solutions to the ever increasing problems of the world.Rather than outright rejecting plastic, the pavilion inspires deep reflection on how we use and manage materials, highlighting our critical responsibility to make sustainable choices for the future.The BOD merges traditional and modern materials—like bamboo, paper, and carbon fiber reinforced plastic (CFRP)—to unlock new and innovative architectural possibilities.Dome A, serving as the striking entrance, is expertly crafted from laminated bamboo. This innovative design not only showcases the beauty of bamboo but also tackles the pressing issue of abandoned bamboo groves in Japan, which pose a risk to land stability due to their shallow root systems.Utilizing raw bamboo for structural purposes is often difficult; however, through advanced processing, it is transformed into thin, laminated boards that boast strength even greater than that of conventional wood. These boards have been skillfully fashioned into a remarkable 19-meter dome, drawing inspiration from traditional Japanese bamboo hats. This project brilliantly turns an environmental challenge into a sustainable architectural solution, highlighting the potential of bamboo as a valuable resource.Dome B stands as the central and largest structure of its kind, boasting a remarkable diameter of 42 meters. It is primarily constructed from Carbon Fiber Reinforced Polymer (CFRP), a cutting-edge material revered for its extraordinary strength-to-weight ratio—four times stronger than steel yet only one-fifth the weight. While CFRP is predominantly seen in industries such as aerospace and automotive due to its high cost, its application in architecture is pioneering.In this project, the choice of CFRP was not just advantageous; it was essential. The primary goal was to minimize the foundation weight on the reclaimed land of the Expo site, making sustainability a top priority. To mitigate the environmental consequences of deep foundation piles, the structure had to be lighter than the soil excavated for its foundation. CFRP not only met this stringent requirement but also ensured the dome's structural integrity, showcasing a perfect marriage of innovation and environmental responsibility.Dome C, with its impressive 19-meter diameter, is crafted entirely from paper tubes that are 100% recyclable after use. Its innovative design features a three-dimensional truss structure, connected by elegant wooden spheres, evoking the beauty of molecular structures.To champion sustainability and minimize waste following the six-month Expo, the entire BOD pavilion has been meticulously designed for effortless disassembly and relocation. It is anchored by a robust steel foundation system and boasts a modular design that allows it to be conveniently packed into standard shipping containers. After the Expo concludes, this remarkable pavilion will be transported to the Maldives, where it will be transformed into a stunning resort facility, breathing new life into its design and purpose.Recently, Shigeru Ban's Paper Log House was revealed at Philip Johnson's Glass House Venue. In addition, Ban installed his Paper Partition Shelters (PPS) for the victims of the Turkey-Syria earthquake in Mersin and Hatay provinces of Turkey.All images © Hiroyuki Hirai unless otherwise stated.> via Shigeru Ban Architects 

Researchers from the US-based University of Massachusetts Amherst (UMass), in collaboration with the Massachusetts Institute of Technology (MIT) Department of Mechanical Engineering, have applied cold spray to repair the deteriorating “Brown Bridge” in Great Barrington, built in 1949. The project marks the first known use of this method on bridge infrastructure and aims to evaluate its effectiveness as a faster, more cost-effective, and less disruptive alternative to conventional repair techniques. “Now that we’ve completed this proof-of-concept repair, we see a clear path to a solution that is much faster, less costly, easier, and less invasive,” said Simos Gerasimidis, associate professor of civil and environmental engineering at the University of Massachusetts Amherst. “To our knowledge, this is a first. Of course, there is some R&D that needs to be developed, but this is a huge milestone to that,” he added. The pilot project is also a collaboration with the Massachusetts Department of Transportation (MassDOT), the Massachusetts Technology Collaborative (MassTech), the U.S. Department of Transportation, and the Federal Highway Administration. It was supported by the Massachusetts Manufacturing Innovation Initiative, which provided essential equipment for the demonstration.

Tackling America’s Bridge Crisis with Cold Spray Technology Nearly half of the bridges across the United States are in “fair” condition, while 6.8% are classified as “poor,” according to the 2025 Report Card for America’s Infrastructure. In Massachusetts, about 9% of the state’s 5,295 bridges are considered structurally deficient. The costs of restoring this infrastructure are projected to exceed $190 billion—well beyond current funding levels.  The cold spray method consists of propelling metal powder particles at high velocity onto the beam’s surface. Successive applications build up additional layers, helping restore its thickness and structural integrity. This method has successfully been used to repair large structures such as submarines, airplanes, and ships, but this marks the first instance of its application to a bridge. One of cold spray’s key advantages is its ability to be deployed with minimal traffic disruption.  “Every time you do repairs on a bridge you have to block traffic, you have to make traffic controls for substantial amounts of time,” explained Gerasimidis. “This will allow us to [apply the technique] on this actual bridge while cars are going [across].” To enhance precision, the research team integrated 3D LiDAR scanning technology into the process. Unlike visual inspections, which can be subjective and time-consuming, LiDAR creates high-resolution digital models that pinpoint areas of corrosion. This allows teams to develop targeted repair plans and deposit materials only where needed—reducing waste and potentially extending a bridge’s lifespan. Next steps: Testing Cold-Sprayed Repairs The bridge is scheduled for demolition in the coming years. When that happens, researchers will retrieve the repaired sections for further analysis. They plan to assess the durability, corrosion resistance, and mechanical performance of the cold-sprayed steel in real-world conditions, comparing it to results from laboratory tests. “This is a tremendous collaboration where cutting-edge technology is brought to address a critical need for infrastructure in the commonwealth and across the United States,” said John Hart, Class of 1922 Professor in the Department of Mechanical Engineering at MIT. “I think we’re just at the beginning of a digital transformation of bridge inspection, repair and maintenance, among many other important use cases.” 3D Printing for Infrastructure Repairs Beyond cold spray techniques, other innovative 3D printing methods are emerging to address construction repair challenges. For example, researchers at University College London (UCL) have developed an asphalt 3D printer specifically designed to repair road cracks and potholes. “The material properties of 3D printed asphalt are tunable, and combined with the flexibility and efficiency of the printing platform, this technique offers a compelling new design approach to the maintenance of infrastructure,” the UCL team explained. Similarly, in 2018, Cintec, a Wales-based international structural engineering firm, contributed to restoring the historic Government building known as the Red House in the Republic of Trinidad and Tobago. This project, managed by Cintec’s North American branch, marked the first use of additive manufacturing within sacrificial structures. It also featured the installation of what are claimed to be the longest reinforcement anchors ever inserted into a structure—measuring an impressive 36.52 meters.
