Smashing a 3D-Printed Ghost Gun Won't Stop Forensic Data Recovery – Here's Why

The Hidden Risks of 3D Printing and the Rise of Ghost Guns

The rapid advancement of 3D printing technology has revolutionized manufacturing, offering new ways to create tools, spare parts, and even artistic designs. However, this innovation also brings with it a growing concern: the emergence of “ghost guns.” These are firearms produced outside traditional regulatory systems, making them difficult to trace and increasingly linked to violent crimes. One such incident involved the 2024 killing of UnitedHealthcare CEO Brian Thompson, which highlighted the urgent need for better tracking mechanisms.

Embedding Forensic Data in 3D-Printed Objects

In response to these challenges, researchers have developed a system that could change how forensic investigations approach 3D-printed items. Known as Secure Information Embedding and Extraction (SIDE), this framework aims to make it harder for illicit objects—like ghost guns—to go undetected. The system allows for the embedding of unique data into printed objects, including timestamps, geolocation information, and printer identification details.

Unlike previous methods, SIDE is designed to withstand attempts to destroy or tamper with an object. Even if a 3D-printed item is broken into pieces, investigators may still be able to recover critical forensic information. This breakthrough was inspired by earlier work presented at the IEEE International Symposium on Information Theory in 2024, which explored encoding techniques that can reconstruct data from partial remains.

How SIDE Works and Its Implications

The SIDE system uses mathematical methods to ensure that fragments of a 3D-printed object retain enough encoded detail for forensic analysis. This means that even if a weapon is deliberately shattered, key information might still be recoverable. The system also includes security mechanisms that could require 3D printers to automatically embed these fingerprints during the printing process.

While this development offers significant benefits for law enforcement, it also raises important questions about privacy and surveillance. For instance, a beginner’s 3D printer used for simple home projects might soon face the same regulatory requirements as industrial machines if such systems become mandatory. This could lead to broader concerns about control over personal manufacturing and the balance between public safety and individual freedom.

Beyond Weapon Tracing: Wider Applications of SIDE

Although the primary focus of SIDE is on tracking ghost guns, its potential applications extend far beyond that. Any item produced using a 3D printer could theoretically carry an invisible signature, allowing investigators to trace its origin. When combined with AI tools for pattern recognition and data recovery, this technology could help reconstruct timelines and identify individuals based on fragments of plastic or resin.

Netanel Raviv, assistant professor of computer science & engineering at Washington University in St. Louis, emphasized the significance of this work. He stated that SIDE opens up new ways to protect the public from the harmful aspects of 3D printing through a combination of mathematical contributions and advanced security mechanisms. While the system may not be foolproof against highly skilled adversaries, it raises the bar for those attempting to evade detection.

Balancing Innovation and Regulation

As 3D printing continues to evolve, so too must the measures in place to address its risks. The development of systems like SIDE represents a crucial step toward ensuring that this powerful technology is used responsibly. However, the debate surrounding regulation will likely involve complex discussions about the boundaries of surveillance, the rights of individuals, and the role of government in overseeing technological advancements.

Ultimately, the future of 3D printing will depend on finding a balance between fostering innovation and safeguarding public safety. With continued research and collaboration between scientists, policymakers, and industry leaders, it may be possible to harness the full potential of 3D printing while minimizing its risks.

9 to 5 Is 'Outdated,' Says HR Expert: Employees Want Freedom

The Shift in Workplace Norms

With the increasing prevalence of remote work, many employees no longer require a physical presence in an office for eight hours a day. This shift calls for companies to reevaluate and adapt their workplace norms, according to Anessa Fike, founder and CEO of fractional HR consulting firm Fike+ Co and author of The Revolution of Work. Fike argues that the traditional 9-to-5 schedule is outdated and fails to align with modern life demands.

Fike highlights that the standard work model poses challenges for employees trying to balance other responsibilities. For instance, the 9-to-5 schedule often conflicts with school hours, making it difficult for parents to manage child care. She emphasizes that this rigid structure contributes to burnout and disengagement among workers.

The Impact of the Pandemic on Work Culture

The COVID-19 pandemic served as a catalyst for change in the workplace. Many employees experienced the benefits of remote or hybrid work during the pandemic and are now resisting strict schedules and return-to-office mandates. Fike notes that people are increasingly tired of being directed on what to do, emphasizing that the current working environment is unsustainable.

Companies may be hesitant to relax their hours and location requirements for several reasons. One significant factor is the desire to recoup costs associated with office space. Fike suggests that real estate owners have a vested interest in maintaining office spaces, which drives the push for return-to-office policies.

Additionally, RTO mandates can serve as a control mechanism for managers who struggle to effectively manage teams without in-person interactions. Fike believes that some leaders prefer to avoid the effort required to adapt to new management styles, stating that they often use excuses like "it's hard" or "that wouldn't work for us."

The Need for Flexibility

Lack of flexibility in work arrangements has led many employees to seek alternative employment opportunities, such as freelance or contract work. Fike points out that employees are frustrated by the lack of autonomy in deciding where and when they work, including meal times. She asserts that adults should not be subjected to such restrictions.

Embracing a Flexible Future

The future of work lies in flexibility. Fike emphasizes the importance of understanding and meeting the needs of individual employees. While some Gen Z employees value in-office time for learning from peers, others prefer to avoid offices altogether. Fike acknowledges that productivity varies among individuals and that a one-size-fits-all approach is ineffective.

She shares her own experience of discovering her peak productivity hours after leaving a corporate setting. Fike believes that helping individuals identify their optimal working times early in their careers could significantly enhance productivity.

One effective strategy she has observed is the implementation of "core hours," allowing employees to create their own schedules while ensuring availability during specific time frames. Fike encourages businesses to engage with employees, experiment with different work models, and find solutions that suit their needs.

Why Mending Clothes Is Trendy Again

The Rise of Mending as a Fashion Trend

In today’s world, where fashion trends often revolve around new purchases and fast fashion, one of the most exciting developments this summer is not an item but an activity: mending. Repairing your own clothes has become more than just a practical choice—it's a statement of values, a creative expression, and a way to connect with your wardrobe on a deeper level.

Mending is increasingly seen as a smart decision, both financially and environmentally. It combines the satisfaction of craftsmanship with the benefits of saving money and reducing waste. As more people embrace this idea, it’s no surprise that a growing number of stylish individuals—men and women alike—are taking their clothing care into their own hands.

While many of us can sew on a button or fix a loose hem, tackling more complex repairs can feel daunting. However, the landscape is changing. Workshops are becoming more common, and online platforms like YouTube and TikTok offer countless tutorials. What’s more, expectations around what a repair should look like have evolved. Perfection is no longer the goal.

Invisible mending, which requires advanced skill, is still essential for preserving high-end or delicate garments. But visible mending is gaining popularity as a bold and creative approach. Using colorful stitches to cover moth holes or rips in beloved jeans turns flaws into unique features. These imperfections become part of a garment’s story, transforming it into a wearable piece of art.

Skye Pennant, founder of the Slow Stitch Club, has been offering workshops in visible mending since 2020. She emphasizes the empowering nature of these techniques, noting that investing time and care into repairing something makes it feel more valuable. “I always say, think about your clothes as a wearable scrapbook of your memories,” she explains. For her, each rip in a mended jacket tells a story, reminding her of the moments that shaped it.

Andrea Cheong, author of Why Don’t I Have Anything To Wear?, has long advocated for learning to sew as a way to connect with clothing and shop more mindfully. When her own repair content gained traction, she began hosting mending classes for her followers. She believes visible mending satisfies a desire for personalization in an era dominated by mass-produced fashion. “We’re always trying to express who we are through our clothes,” she says. “What better way to say, ‘this is who I am’ than by mending something yourself?”

The emotional benefits of mending are also evident. Emily Zak, a consultant and journalist, used to be a shopping addict. In 2024, she took a break from buying new items and focused on repairing her existing wardrobe. Many of her pieces needed professional help, but she also learned to sew at her local dry cleaners. “The biggest surprise was how I felt about it,” she recalls. “I thought it would be difficult, but instead, it was incredibly rewarding.”

Six months later, she continues to shop less while still enjoying fashion. Her experience shows that mending can provide the same dopamine rush as buying something new—without the environmental cost.

Getting Started with Mending

If you're interested in trying mending, there are several steps you can take to begin:

• Practice on old items: Start with a tea towel or a holey sock to get comfortable with the techniques.
• Choose the right tools: A regular needle works, but a tapestry darning needle is ideal for knits, while a sashiko needle suits denim and cotton.
• Use affordable materials: Look for embroidery thread in charity shops, where there’s usually a good selection.
• Experiment with thread: Embroidery thread consists of six strands. Depending on the fabric, you can separate them to make the thread last longer.

Mending is more than just fixing something—it’s a way to reconnect with your clothes, express your individuality, and contribute to a more sustainable future. Whether you're a seasoned sewer or a complete beginner, there’s never been a better time to pick up a needle and thread. After all, those moths might just be helping us rediscover the beauty of repair.

Nike's New Running Top Keeps You Cool With Smart Design

A New Era of Running Gear Innovation

When it comes to innovation in running gear, the spotlight is often on shoes, especially with the rise of carbon plate technology that has revolutionized performance. However, the advancements in running apparel are just as impressive and are beginning to capture attention.

Nike, a leader in athletic wear, has recently introduced a new piece of running gear that's making waves: the Radical AirFlow garment. This t-shirt is designed to keep runners cool and comfortable during long-distance runs, particularly on trails. The top has already proven its effectiveness through rigorous testing by Nike athletes, including Caleb Olson, who wore it while winning the Western States 100-mile race in June.

A Shirt Full of Holes

The Radical AirFlow top uses a unique material called Radical AirFlow, which features numerous holes to enhance airflow and speed up sweat evaporation. This design is inspired by the Bernoulli Principle of fluid dynamics, specifically the Venturi Effect. Every element of the shirt has been carefully considered to promote optimal airflow to the skin.

Jahan Behbahany, Senior Director of Nike Apparel Innovation, explained the development process: “We tried all kinds of airduct configurations, sizes, and zonal placements throughout the testing and development. We found that a funnel-shaped construction of larger to smaller gradient holes, uniformly placed, would best ‘funnel’ and accelerate air to the skin.”

In addition to the smaller holes covering the entire top, there are larger cutouts under the arms and at the elbows, which provide extra ventilation and comfort. These features help reduce the risk of chafing in sensitive areas. The cropped design also improves airflow to the abdomen, making it easier for athletes to access their waist belt during ultramarathons.

The materials used in the top are designed to dry quickly and absorb less sweat and water than traditional tops, further enhancing comfort during long runs.

The Future of Trail Running

While the Radical AirFlow top may not be the most conventional choice for everyday runners, its benefits could make it an appealing option for those looking to improve performance. However, it will not be available to the general public until 2026. In 2025, only Nike elite athletes will have access to the top as it continues to be refined for its retail launch next year.

Alongside the innovative top, Nike has also launched the ACG Ultrafly, a trail-running shoe that builds upon the success of the previous model. This new version is lighter and more flexible, thanks to a redesigned carbon plate that allows for greater flexibility on uneven terrain. The upper has also been updated to be more breathable and to drain water faster.

The midsole remains composed of Nike’s springy ZoomX foam, and the sockliner is made from the same material. A Vibram Litebase outsole ensures grip on various surfaces, making the ACG Ultrafly suitable for a wide range of trail conditions.

Like the Radical AirFlow top, the ACG Ultrafly will not be available for purchase until 2026. The price has yet to be announced, but it is expected to be similar to the $270 / £230 price tag of the previous model.

As Nike continues to push the boundaries of running gear, both in terms of footwear and apparel, it's clear that the future of running is being redefined. Whether it's through groundbreaking shoe technology or innovative clothing designs, the brand is setting new standards for performance and comfort.

Shattering a 3D-Printed Ghost Gun Won't Stop Forensic Data Recovery – Here's Why

The Rise of 3D Printing and the Challenge of Ghost Guns

The rapid advancement of 3D printing technology has transformed the way people create objects, from simple household items to complex mechanical parts. While this innovation has opened up new possibilities in manufacturing, it has also introduced challenges, particularly in the form of “ghost guns.” These are firearms produced without traditional regulatory oversight, making them difficult to trace and increasingly linked to violent crimes. One such incident involved the 2024 murder of UnitedHealthcare CEO Brian Thompson, which highlighted the dangers associated with untraceable weapons.

To address these concerns, researchers have developed a groundbreaking system that could help forensic investigators recover critical data even if a 3D-printed object is destroyed. This innovation, known as Secure Information Embedding and Extraction (SIDE), represents a significant step forward in combating the misuse of 3D printing technology.

Fingerprinting in 3D Printing: A New Approach

Fingerprinting in 3D printing is not a new concept. Over the years, various methods have been explored to embed unique identifiers into printed objects. These identifiers can include details such as timestamps, printer identification, and geolocation data. However, a major challenge has always been ensuring that this information remains intact even if the object is damaged or tampered with.

A team led by Netanel Raviv at Washington University in St. Louis has tackled this issue with the development of the SIDE system. This framework uses advanced mathematical techniques to ensure that even if a 3D-printed object is broken into pieces, enough encoded data remains to allow for forensic recovery. The system builds upon earlier research presented at the IEEE International Symposium on Information Theory in 2024, which focused on encoding methods that can reconstruct data from partial remains.

Enhancing Security and Data Recovery

One of the key features of the SIDE system is its ability to embed information in a way that is resistant to tampering. Unlike traditional marking methods, SIDE employs loss-tolerant embedding techniques. This means that even if an object is deliberately destroyed, investigators may still be able to extract valuable forensic data during analysis.

This development could significantly impact the detection and tracking of illicit 3D-printed items, including ghost guns. By making it harder for such weapons to go undetected, the system could help reduce their circulation and potential for harm. However, it also raises important questions about surveillance, personal manufacturing, and the balance between security and privacy.

Broader Applications Beyond Weapon Tracing

While the initial focus of SIDE has been on tracing 3D-printed weapons, the technology has the potential for much wider applications. Any object produced using a 3D printer could theoretically carry an invisible signature, making it possible to track and identify items through forensic analysis.

When combined with AI tools for pattern recognition and data recovery, this could enable investigators to reconstruct timelines and identify individuals based on fragments of plastic or resin. This could prove invaluable in a variety of forensic contexts, from criminal investigations to product recalls.

Balancing Innovation and Regulation

Despite its promise, the SIDE system is not without limitations. It may not be fully effective against highly skilled adversaries who have expertise in 3D printing. However, it does raise the bar for those attempting to evade detection, requiring a higher level of sophistication and knowledge to remain undetected.

As the technology continues to evolve, the debate over its regulation will likely intensify. A basic 3D printer used for harmless home projects might soon face the same requirements as industrial machines if regulators choose to implement such systems. This could lead to broader implications for personal manufacturing and the use of 3D printing in everyday life.

The Future of 3D Printing and Forensic Technology

The work behind the SIDE system highlights the potential for combining mathematical innovations with new security mechanisms to protect the public from the harmful aspects of 3D printing. As the technology becomes more widespread, the need for robust forensic tools will only grow.

Researchers like Netanel Raviv continue to explore ways to enhance the security and traceability of 3D-printed objects. Their efforts underscore the importance of balancing innovation with responsibility, ensuring that the benefits of 3D printing are realized without compromising public safety.
