Scientists Find Fast Track to Rare Metal Recovery: Paves the Way for Eco-Friendly Future
A groundbreaking recycling method developed by researchers in China promises to revolutionize the way we handle waste from lithium-ion batteries, according to a report by the Independent. These batteries, which power everything from smartphones to electric vehicles, are made with rare metals like lithium, nickel, cobalt and manganese. Traditionally, mining these materials has caused significant environmental harm. The new study outlines a process that recovers nearly 100 percent of these valuable metals in just 15 minutes. Researchers from Central South University in Changsha, Guizhou Normal University, and the National Engineering Research Center of Advanced Energy Storage Materials have published their findings on this innovative technique. The process begins with using tiny batteries to break down the metals within spent batteries. Glycine, an environmentally friendly amino acid, is then used for extraction—offering a safer alternative to previous chemical methods. The results are impressive: 99.99 percent of lithium, 96.8 percent of nickel, 92.35 percent of cobalt, and 90.59 percent of manganese can be recovered. This advancement could significantly reduce the environmental impact associated with electric vehicles (EVs), which rely heavily on these rechargeable technologies. By utilizing recycled materials for battery production and ensuring they can be recycled again at the end of their life cycle, EVs could become more cost-effective and eco-friendly. The researchers believe this method will pave the way for new opportunities in clean energy technology. "This green and efficient strategy in neutral solution environment opens a new pathway to realise the large-scale pollution-free recycling of spent batteries," they stated in their study.g vehicles and enhancing climate protection efforts worldwide.

Weekend Warriors Rejoice: New Study Reveals Surprising Health Boost for Diabetics
Exercise is great for your health; that's no secret. But what if you can only squeeze in a workout on the weekend? A new study suggests that even so-called "weekend warriors" get significant benefits, especially those with diabetes. A team of researchers from the US, China, and Australia focused on people with diabetes, who can see particular benefits from exercise like reduced insulin resistance. They understand how tough it can be to fit regular workouts into a hectic schedule. "Many people struggle to engage in regular physical activity throughout the week due to time constraints," they note in their published findings. To explore this further, they looked at 51,650 adults with diabetes and divided them into four groups: those doing no moderate-to-vigorous physical activity (MVPA), those exercising less than 150 minutes per week, those hitting 150 minutes in three or more sessions weekly, and the weekend warriors achieving 150 minutes in just one or two sessions. The results were promising for all who exercised but particularly striking for weekend warriors. Those who spread their exercise across three or more sessions had a 17 percent lower risk of death during the study period and a 19 percent lower risk from cardiovascular issues. Weekend warriors saw even better outcomes with a 21 percent reduction in overall mortality risk and a whopping 33 percent drop in cardiovascular-related mortality risk. Even participants who didn't reach the full 150 minutes still experienced lower all-cause mortality compared to non-exercisers. The team emphasizes that any physical activity is beneficial for individuals with diabetes. While the study doesn't identify cause-and-effect relationships—it relies on self-reported data and focuses solely on people with diabetes—it aligns with previous research showing that any exercise is advantageous. Most past studies suggest that as long as you're meeting recommended targets, whether you cram it into weekends or spread it out across the week, you'll reap similar health benefits. This news is heartening for anyone struggling to find time for weekday gym visits. Researchers also highlight that previous studies involving general populations indicate similar mortality benefits for weekend warriors as for consistently active individuals. Still, these estimates may vary based on different population characteristics. This latest research provides yet another reason not to skip your weekend workout if that's when you can fit it in. The study appears in the Annals of Internal Medicine.

This Navy Veteran is Celebrating His 100th Birthday With A Unique Submarine Surprise
Roger Wood, a Royal Navy veteran and former radar mechanic during World War Two, marked his 100th birthday in a rather special location: aboard the historic submarine HMS Alliance. The vessel, now part of the Royal Navy Submarine Museum in Gosport, shares its own milestone this year as it turns 80. Wood’s visit was poignant and filled with nostalgia. As he stepped onto the deck of HMS Alliance, he quipped about the time passed since his last encounter with such a vessel: "It's been a few years since I was here." Standing alongside family and friends, he reflected on his wartime service. "It's always nice to look back on it and think, 'yes, I was part of that,'" Wood shared. Before his naval service, Wood worked as a radio transmitter engineer for the BBC. His technical skills transitioned seamlessly into his role as a radar mechanic in the Royal Navy, where he maintained submarine radars during the war. His contributions were integral during an era when technology played an increasingly crucial role in naval operations. HMS Alliance holds its own storied past. Launched towards the end of World War Two, it served through significant periods like the Cold War. However, after decades of service, it fell into disrepair. In 2014, extensive restoration efforts transformed it into a museum piece—a living testament to history and sacrifice. Today, HMS Alliance stands as Britain’s sole surviving World War Two-era submarine and serves as a memorial to the 5,300 British submariners who have lost their lives in service from 1904 to today. Visitors can explore its compartments and gain insight into what life was like aboard these vessels during tense times. The alliance between Roger Wood's personal history and that of HMS Alliance creates an evocative tableau of memory and legacy. For those at the celebration, Wood's centennial birthday became more than just a personal milestone; it was also a reminder of collective endurance and history preserved within the steel hulls beneath ocean waves. As Wood celebrated surrounded by loved ones and historical reverence alike, he likely found comfort in knowing that both he and HMS Alliance continue to share stories of resilience with future generations.

800 Ancient Treasures Unearthed in Yorkshire Find Permanent Home
In a North Yorkshire field, an exciting find has found its permanent home. The Melsonby Hoard, a stunning collection of more than 800 Iron Age artifacts, is now part of the Yorkshire Museum's extensive collection. This treasure trove is believed to be one of the UK's largest finds from that era, discovered by metal detectorist Peter Heads and excavated with assistance from Durham University. Dr. Andrew Woods, head of research and collections at York Museums Trust, can't hide his excitement about this remarkable addition. "The museum has been collecting for 200 years and we have nothing like this," he remarked. "To share that with people and tell new stories is one of the best days of my career." The discovery was first reported in December 2021, leading to an excavation supported by the British Museum and Historic England grants. Among the treasures unearthed were partial remains of more than seven wagons and chariots, along with horse harnesses and ceremonial spears. After preservation efforts at Durham University, the Yorkshire Museum launched a fundraising campaign earlier this year to secure the hoard for its collections. Dr. Woods was "blown away" by public support; £54,000 came from online donations alone. Additional funding included a significant £192,096 grant from the National Heritage Memorial Fund. Kathryn Blacker, chief executive of York Museums Trust, expressed her delight at securing such an important piece of Yorkshire’s history: "Thanks to generous donations from members of the public and the support from the National Heritage Memorial Fund, the hoard will remain here in Yorkshire for everyone to see and enjoy." Dr. Woods sees this acquisition as just the start for these artifacts: "Keeping the hoard close to where it was found means we can tell the story of the North." After further preservation efforts and research projects, these fascinating pieces will be on public display at the museum.

This Critically Endangered Bird Just Reproduced in South Korea for the First Time in Decades
In an exciting development for wildlife conservation, the crested ibis, a bird once considered extinct in South Korea, has successfully reproduced in the wild for the first time in decades. The event took place in South Gyeongsang province, where three chicks were born. This marks a significant moment since the species was declared extinct on the Korean peninsula back in the 1970s. According to Korea JoongAng Daily, these chicks are a promising sign that the ibises released into nature are beginning to establish themselves independently. A local official commented on this milestone: "The successful natural breeding of wild ibises means they are now beginning to settle independently in nature." There is continued commitment towards preserving their natural habitat and managing ecosystems to support these birds. The crested ibis had seen its numbers dwindle drastically across East Asia due to overhunting and habitat destruction. Efforts by Japanese scientists to create a captive breeding program initially failed, leading many to believe that the species might be lost forever. But hope was rekindled when seven resilient individuals were discovered in China’s Qinling Mountains. These birds became the foundation for reviving populations elsewhere. South Korea's current population descends from those Qinling survivors. In an act of goodwill and collaboration, China gifted two pairs of breeding ibises to South Korea in 2008 and 2013. Since then, around 400 birds have been reintroduced into the wild as part of efforts to stabilize their presence. Japan is also witnessing success with its crested ibis population. After losing its last wild ibis in 2003, Japan worked hard to reestablish them on Sado Island. Conservation initiatives have led to nearly 500 ibises thriving there today; they even contribute naturally by controlling pests in rice paddies. This revival story highlights how international cooperation can yield positive outcomes for conservation efforts, even between countries with complex historical ties. Reintroducing species like these requires patience and dedication but plays an essential role in restoring biodiversity. Communities throughout East Asia are actively participating by creating environments conducive for these birds' survival. Their efforts demonstrate how localized actions can make a significant difference globally. As nations continue working together on projects like this one, it becomes clear that shared goals can help preserve and protect our planet’s rich biodiversity.

Meet The Teen DJ Turning Rave Nights Into Eco-Friendly Celebrations
Fifteen-year-old DJ Sam Seven has found a way to mix beats with climate action, the BBC reports. His event, called Wasted, is all about raving without trashing the planet. The teenager bans plastic at his events, encourages carpooling, and makes his signage out of recycled materials. He is also looking at biodegradable glowsticks to replace the usual single-use plastic ones. “For me, as a 15-year-old, this is about my future,” he told the BBC. That future, he knows, could include worse wildfires, longer droughts, stronger hurricanes, and rising sea levels, all predicted by NASA unless action is taken. Sam admits that talking about the climate can “be a bit of a boring subject for some people,” so he uses music and dancing to get the message across. “When you bring people together, it’s easier to talk about it without sounding preachy,” he said. After two events at the Playbox Theatre, the response has been good, he says, and the idea is catching on. He is not alone in trying to make nightlife greener. In the Netherlands, a company called Energy Floors has built The Kinetic Dancefloor, a system that generates about 2 watts of power with every step. The British band Coldplay has used that technology on tour. In Scotland, the firm TownRock Energy has developed BODYHEAT, which captures the warmth of clubgoers and turns it into renewable energy. Other teenagers are doing their part in different ways. In Utah, two high school students have been collecting donated gowns so that promgoers can pick one for free. That cuts costs and reduces waste from the fashion industry, which the UN Environment Programme says produces 2 to 8 percent of global carbon emissions. Small changes like these aim to slow down the damage done by carbon emissions and plastic waste. They may not stop the crisis on their own, but for Sam, every beat counts.

Beloved Korean BBQ Spot Serves Up Free Meals, Community Spirit for 15,000 and Counting
In the sweltering July heat of Austin, Texas, a curious sight unfolds outside Korea House Restaurant every first Wednesday of the month. A line forms as people gather for a meal at this pioneering Korean BBQ spot. But these aren't just any patrons—they're there to enjoy a free meal, courtesy of the restaurant's owners and staff who are committed to serving their community. Since opening in 1988, Korea House has become an institution for both its culinary offerings and its charitable spirit. The eatery recently surpassed its 15,000th free meal milestone, a testament to the dedication of co-owners Vivian Newton and Pok-Cha Kim. Both have been digging into their savings to continue this tradition but remain undeterred in their mission. "We’re not rich, but when we share with others, always God provide us better things somehow," Newton shared. "If we have to close down, we’ll close down. But until then, we’re just going to keep on going." The concept is simple: come in and eat without worrying about the bill. Tips and donations are accepted but not expected; they are often pooled together to help Austin’s homeless population, many of whom rely on these meals. For people like Moses Yoo, an unhoused Korean American who visited recently, the experience was more than filling—it was nostalgic. "That first taste brought [me] back to Korea," Yoo told KUT News. "It was nice to have someone speak back Korean." Korea House's initiative also resonates with students from local universities who appreciate some financial respite. For some students who grew up visiting Korea House with their families, eating there now brings back fond memories. The driving force behind this generous effort is Newton and Kim’s Christian faith. From the decor to the music playing inside the restaurant, it is clear that they hope guests leave spiritually nourished as well as physically satisfied. As long as they can manage it financially, Korea House owners say they will continue feeding anyone who walks through its doors on those special Wednesdays each month, providing a warm meal and a sense of community in Austin.

Meta's New Bracelet Turns Hand Movements Into Digital Magic
Meta, Facebook’s parent company, just introduced a sci-fi-like invention that translates hand gestures into computer actions. Engineers at Meta's Reality Labs developed a bracelet that can interpret fine motor movements, such as dotting a lowercase "i," and transform handwriting into digital text with remarkable efficiency. This new device emerges from the same labs that once championed the Metaverse project. The bracelet stands out because it reads electrical signals from muscle movements at the wrist, translating them into computer commands without needing invasive procedures or personal calibration. It fits like any regular bracelet, offering ease of use. Patrick Kaifosh and Thomas Reardon led its development by employing deep learning to create universal decoding models. These models accurately interpret muscle movements across different users without requiring individual adjustments; the more people use it, the more precise it becomes. While personalization further boosts its accuracy and performance, the generic model already offers significant capabilities. Connected via Bluetooth, this device can translate human handwriting into text at around 20.9 words per minute—a bit slower than an average mobile phone user's speed but still impressive for early technology. Who might benefit most from this invention? Consider individuals with disabilities or paralysis and those below-the-elbow amputees who would find hands-free computing revolutionary. Additionally, professionals working with multiple computers could welcome such innovation for multitasking efficiently. The promise of this tech lies not only in its current applications but also in its potential to evolve and adapt through increased usage and feedback.

Rare (and Tiny) Gecko Rediscovered: A Surprising Return in the Galápagos
Scientists have confirmed a conservation success story in the Galápagos: a tiny gecko species once believed extinct has been rediscovered on Rábida Island. The Leaf-toed gecko (Phyllodactylus maresi) was previously known only from 5,000-year-old fossils. Live specimens, collected by the nonprofit Island Conservation, have now been documented and described in the journal PLOS ONE. The discovery comes more than a decade after a major rewilding effort removed invasive rodents from the island. “This rediscovery highlights nature’s incredible power to heal itself when given the chance,” said Paula Castaño, Island Conservation’s Impact Program Manager. “When you rebalance an ecosystem, it can bounce back quickly and dramatically.” In 2011, Island Conservation, working with the Galapagos National Park, the Charles Darwin Foundation and The Raptor Center, led the eradication of non-native rodents that had been devastating Rábida’s wildlife. Within a year, biologists surveying the restored landscape spotted the small nocturnal lizard—proof that it had survived in hiding all along. Follow-up research by Island Conservation, the QCAZ Museum of Zoology at Ecuador’s Pontifical Catholic University, Re:wild, and the Galápagos National Park Directorate confirmed that the population on Rábida is genetically distinct, making it an important conservation unit. DNA sequencing and morphological analysis showed the geckos are closely related to their counterparts on nearby islands but have evolved as a separate lineage. The rediscovery underscores the potential of island restoration projects to bring species back from the brink. Similar programs elsewhere in the world have shown how quickly ecosystems can rebound once invasive species are removed. “This archipelago still holds hidden surprises, waiting to be discovered,” said Omar Torres-Carvajal, Curator of Reptiles at the QCAZ Museum of Zoology. The find also adds to a string of positive Galápagos conservation stories in recent years, from the reintroduction of 500 giant tortoises to the confirmation that a giant tortoise found on Fernandina Island belongs to a species once thought extinct. For conservationists, the little gecko is a reminder that with bold intervention and patience, biodiversity can recover in ways no one expects.

How #PopScope Is Bringing the Cosmos to City Streets
Imagine heading out for ice cream and instead coming face to face with Saturn’s rings. That’s the kind of surprise thousands of people have experienced thanks to #PopScope, a grassroots astronomy project that just celebrated a major milestone: 500 pop-up telescope events. Now in its 11th year, the volunteer-run group has introduced 26,000 people to the night sky in cities across Canada, the United States, and as far away as Ireland, Malawi, and India. It all started in Ottawa in 2014 with a simple idea: set up a telescope in a public place, point it at the moon, Jupiter, or Saturn, and invite anyone walking by to take a look. The reactions are what keep the volunteers coming back. “Jaws drop, eyes widen, and whispers are uttered when they encounter our awesome universe,” co-founder Michael O’Shea told the Good News Network. “We’re motivated by the look of awe on a stranger’s face when they see Saturn’s rings for the first time, or hear cries of delight when someone views the Moon’s bumpy craters in vivid detail,” he said. What begins as a peek through a telescope often turns into a conversation—about the phases of the moon, neighborhood stories, or even the name of someone’s dog. Sometimes those conversations turn into friendships. Over the years, volunteers have collected plenty of memorable comments: “I am 55 years old and I’ve never seen anything like this before. Thank you for coming!” “Saturn rings! They look like an emoji! A Saturn emoji!” “You made my night…Best thing that happened to me all day.” “The Moon—It’s like cheese!” “I might be late for my train, but it was worth it to see the moon!” The project has been funded and equipped by donors like Celestron, the Awesome Foundation, and the Social Innovation Lab, allowing it to bring telescopes to communities that may not have easy access to science institutions. Chapters now operate in Montreal, Baltimore, New York City, Washington, D.C., Boston, Philadelphia, and Jacksonville, Florida. #PopScope doesn’t know if these encounters will lead kids to careers in space science. What they hope is simpler: that people, young and old, will keep looking up. For events, photos, or to volunteer, visit popscope.org.

Cracking the Egg Myth: New Study Shows Eggs Are Healthier Than You Think
Eggs have been a breakfast staple for generations, but their reputation has been scrambled over the years. Are they good for you or not? A new study suggests they might be better than we thought. Researchers from the University of South Australia have investigated how eggs impact cholesterol levels, focusing on their saturated fat and cholesterol content. Jonathan Buckley, an exercise scientist from the university, notes that "eggs have long been unfairly cracked by outdated dietary advice." The study aimed to separate the effects of cholesterol and saturated fat on low-density lipoprotein (LDL) cholesterol, often referred to as 'bad' cholesterol. The team recruited 61 adults with similar baseline LDL cholesterol levels and placed them on three different diets for five weeks each. Out of these, 48 participants completed all three diet phases. The first diet was high in cholesterol but low in saturated fat and included two eggs per day. The second diet was low in cholesterol but high in saturated fat without any eggs. The third combined high levels of both cholesterol and saturated fat, including one egg per week. The study's results were revealing. Diets high in saturated fat correlated with increased LDL cholesterol levels. In contrast, a diet rich in eggs but low in saturated fat actually reduced LDL cholesterol levels. This suggests that it's not the eggs themselves causing elevated bad cholesterol but rather the presence of saturated fats elsewhere in one's diet. "You could say we've delivered hard-boiled evidence in defense of the humble egg," says Buckley. He highlights that when it comes to a hearty breakfast, bacon or sausages are more likely to harm heart health than eggs. This research adds to growing evidence supporting the nutritional benefits of eggs when consumed as part of a balanced diet low in saturated fats. Eggs are packed with protein and other essential nutrients while having relatively low amounts of saturated fats compared to other animal-based foods. Still, this doesn't mean everyone should rush to eat more eggs without considering overall dietary habits and individual health needs. But for those who enjoy starting their day with an omelet or boiled egg, this study provides some reassurance about their health implications. Published in The American Journal of Clinical Nutrition, these findings encourage a reevaluation of how we view popular dietary choices like eggs within broader nutritional contexts.
