Biodegradable Smart Textile

A groundbreaking study led by the University of Southampton and UWE Bristol in the UK has demonstrated that wearable electronic textiles can now be both sustainable and biodegradable. The research introduced a new approach for fully inkjet-printed, eco-friendly e-textiles, known as SWEET—Smart, Wearable, and Eco-friendly Electronic Textiles. These e-textiles, which integrate electrical components like sensors, batteries, and lights, are used in fashion, sportswear, and medical devices. However, traditional e-textiles often contain non-biodegradable metals, making recycling difficult. This new method utilizes sustainable materials and manufacturing processes to ensure the fabric decomposes at the end of its lifecycle.

The SWEET design features three layers: a sensing layer, an interface layer, and a base fabric made from biodegradable Tencel, a renewable wood-based textile. The active electronics are inkjet-printed using graphene and PEDOT:PSS, conductive materials applied precisely to reduce waste. Tests showed that the fabric could reliably monitor heart rate and temperature to industry standards. Volunteers using gloves embedded with the material confirmed its effectiveness for continuous health monitoring, proving that sustainability does not have to come at the expense of functionality, particularly in critical areas like healthcare.

The biodegradable properties of the material were tested by burying it in soil, where after four months, it lost 48% of its weight and 98% of its strength, indicating effective decomposition. A life cycle assessment revealed that the graphene-based electrodes had 40 times less environmental impact than traditional alternatives. Additionally, the inkjet printing process minimized waste and reduced water and energy consumption compared to conventional screen printing. These advancements make SWEET a promising solution for sustainable e-textiles, with potential applications in early heart disease detection and prevention, aligning functionality with environmental responsibility.

1,200-Year-old Grave

A Viking-age graveyard in southwest Norway, uncovered near the coastal town of Fitjar, has provided fascinating evidence of wealth, continental connections, and the prominent role of women in Viking society. Discovered initially by metal detector enthusiasts, the site at Skumsnes has yielded numerous artifacts, including jewelry, coins, and textile tools, which suggest that the graves belonged to high-status women. Among the finds were a glass bead necklace, a Danish coin from one of the earliest mints in Denmark, and a brooch made from a metal book clasp, possibly originating from a Bible in England or Ireland. These items hint at both raids and trade routes, with brooches and coins from mainland Europe highlighting connections to regions such as the Carolingian Empire.

Despite the rich collection of artifacts, no human remains were found, leading archaeologists to reconsider the site’s original interpretation. While initially thought to be burial graves where remains had disintegrated, the site now seems to serve as a memorial or cenotaph. The discovery that items like the glass bead necklace were stored in leather pouches rather than placed on bodies strengthens this theory. Archaeologist Søren Diinhoff of the University Museum of Bergen suggests that some of the objects might have been obtained through Viking raids, while others likely came from trade routes, underscoring the extensive reach of Viking interactions.

The Skumsnes farm, once a significant manor near the water, likely served as a rest stop for sailors and travelers, providing strategic shelter for passing ships and generating income for its owners. Archaeological tools related to weaving, such as a weaving sword, spindle whorl, and wool shears, suggest the site’s connection to this prestigious trade. In addition, the memorial's boat-shaped stone arrangement, a common motif in Viking ship burials, is completed by a stone at the center resembling female genitalia, thought to honor the women associated with the site. While the team was unable to fully excavate a third grave, metal detector surveys suggest there are many more similar sites nearby, adding to the growing body of Viking-age discoveries across the region.

An Emotional Surprise

On December 28th, at Hawkstone Hall, Elliot Gwilliam was moved to tears when he heard a surprise message from his 3-year-old daughter, Evie, just before marrying her mother, Emma Beddow. The heartfelt message, played over the public address system, had Elliot overcome with emotion: “Hello daddy, it’s me, Evie. I’m walking down the aisle... We love you so so much, to the moon and back.” His reaction was pure and raw, and the moment left many in the audience teary-eyed.

The surprise was coordinated by wedding videographer Owen Bloor, who worked with Emma and Evie to set up the emotional message. "The acoustics of the hall amplified the moment," Bloor explained. "Elliot’s reaction was so genuine." The video has since gone viral, touching millions and becoming a heartwarming testament to love and family.
