The World’s biggest Mars rock could sell for $4 million at auction
A massive Martian meteorite, known as NWA 16788, is making headlines as it heads to auction at Sotheby’s in New York. Weighing in at a hefty 24.5 kilograms, this space rock is the largest known piece of Mars on Earth and could fetch up to $4 million. Unlike most Martian meteorites that are typically small, NWA 16788 stands out due to its size and distinct red hue. The meteorite was discovered in November 2023 in Niger's remote Agadez region. According to Sotheby’s statement released Tuesday, it's about 70 percent larger than any other Martian meteorite found on Earth so far. Only around 400 such meteorites have been discovered globally, making this find exceptionally rare. Cassandra Hatton from Sotheby’s describes NWA 16788 as a "discovery of extraordinary significance." She highlights its "immense size and unmistakable red color" as factors that make it a remarkable specimen from Mars that offers a tangible link to our neighboring planet. Scientists' analysis suggests the meteorite was likely blasted off Mars by an asteroid impact powerful enough to turn parts of it into glass. As it entered Earth's atmosphere, it developed a glassy crust—a testament to its tumultuous journey through space. However, the forthcoming auction has sparked concerns among some experts who believe the meteorite should be preserved for scientific study rather than private ownership. Steve Brusatte from Scotland’s University of Edinburgh expressed worry about the potential for the rock to end up hidden away from public view. “It belongs in a museum, where it can be studied and enjoyed by children and families,” he told CNN. On the other hand, Julia Cartwright from England's University of Leicester offers a different perspective. She argues that the market for collecting and selling meteorites actually benefits scientific research by providing more specimens for study. She points out that collectors often contribute significantly to the availability of samples for scientific examination. Cartwright also notes that while public display would be ideal for NWA 16788, a reference sample has been saved at China's Purple Mountain Observatory. This means researchers will still have access to study part of this extraordinary find, no matter who wins the auction. This isn't the first time Martian rocks have captured attention at auctions; back in February 2021, another Martian meteorite sold at Christie’s for $200,000—far surpassing initial estimates. The fate of NWA 16788 will likely continue to stir interest until its new owner is revealed after July 16th, when Sotheby’s holds its auction.

How Elephant Conservation Efforts Are Turning the Tide: Inspiring Success Stories
In Bangladesh, Uganda, Nepal and India, new strategies are helping people and elephants coexist. It's a critical step in protecting the endangered giants. Bangladesh has around 270 resident Indian elephants, plus several herds that used to migrate from India’s Meghalaya state. But in 2019, a new border fence cut off their route. Trapped in Bangladesh’s northeast, the elephants began raiding farms and orchards, sparking dangerous conflict. After Mongabay reported on the situation in March, the Bangladeshi government announced plans for a new protected area. Zoology professor Mohammed Mostafa Feeroz called it “a good initiative” but warned that the only long-term fix is reopening the elephant corridor. Elsewhere, communities are experimenting with ways to keep elephants away from crops without harming them. In Uganda, nearly 23 kilometers of solar-powered electric fencing, reinforced with “porcupine” wire to foil tusk-wielding fence breakers, has dramatically reduced crop raids near Queen Elizabeth National Park. A survey found nearly 90 percent of locals reported the raids had stopped. Along Nepal’s eastern border with India, farmers shifted from maize to crops elephants dislike, such as tea, bay leaves, and lemons. Conservation groups also worked to ensure more residents receive government compensation for damage, reducing risky confrontations with elephants. In southern India’s tea-growing regions, authorities are testing a “virtual fence”: solar-powered sensors that trigger flashing lights and alarms when large animals approach. Residents say it makes them feel safer, though some elephants still push past or knock over the posts. From physical barriers to smarter farming, these projects show that when communities adapt, both people and elephants stand a better chance of thriving.

Meet GEAIR: The AI Robot Revolutionizing Crop Breeding with Precision and Speed
Chinese scientists have developed the world’s first robot capable of carrying out the entire hybrid crop breeding process, combining artificial intelligence with biotechnology to boost agricultural precision. The robot, called GEAIR, was created by the Institute of Genetics and Developmental Biology at the Chinese Academy of Sciences. In tests inside a greenhouse, it used AI-powered visual recognition to locate flowers, extend its robotic arms, and gently complete hybrid pollination — moving efficiently among plants to repeat the process. “AI and robots offer vast opportunities in shifting hybrid breeding toward precision agriculture to enhance crop yields, reduce costs and promote sustainable practices,” said Xu Cao, a researcher at the institute. Hybrid breeding, which focuses on producing superior crop varieties, is traditionally slow, repetitive, and labor-intensive. Compared with methods used for well-known hybrids like rice, GEAIR can integrate newer approaches such as speed breeding, enabling rapid, customized development of high-performing crops. The system’s visual recognition and precise positioning allow it to navigate crops and perform pollination more efficiently, potentially transforming breeding from an experience-driven craft into a data-driven science. Xu called the work a “successful pioneering effort” in creating a closed-loop system for intelligent, robotized hybrid breeding, a step that could help China advance food security, improve crop quality and meet sustainability goals.

How AI Could Revolutionize Cancer Detection With Just Your Voice
Artificial intelligence might soon help detect a deadly form of cancer just by listening to a patient's voice, according to scientists. Researchers are optimistic that advanced machine learning technology could identify early signs of voice box cancer within a few years. In 2021, there were an estimated 1.1 million cases of this type of cancer worldwide, with around 100,000 resulting in death. Common risk factors for laryngeal cancer include smoking, heavy alcohol use, and human papillomavirus infection. Catching the disease early significantly improves survival rates, which can range from 35 percent to 78 percent over five years when treated based on the tumor's stage and location. Currently, doctors rely on video nasal endoscopy and biopsies to diagnose these cancers. These procedures are invasive and cumbersome. However, researchers have found that abnormalities in the vocal cords can be detected through voice analysis. Vocal fold lesions can be benign or indicate early stages of cancer. An American research team recently published their findings in Frontiers in Digital Health, showing AI's potential to recognize early signs of laryngeal cancer using voice recordings. Dr. Phillip Jenkins from Oregon Health & Science University explained that they used vocal biomarkers to differentiate between voices with and without vocal fold lesions. The researchers are part of the Bridge2AI-Voice project under the US National Institute of Health’s ‘Bridge to Artificial Intelligence’ initiative aimed at tackling complex biomedical issues with AI. The study analyzed changes in tone, pitch, volume, and clarity using the first version of the public Bridge2AI-Voice dataset, which includes 12,523 recordings from 306 participants across North America. The dataset included voices from individuals with known laryngeal cancer as well as other conditions like spasmodic dysphonia and unilateral vocal fold paralysis. By focusing on acoustic features such as pitch variability and harmonic-to-noise ratio (a measure comparing harmonic sounds to noise), they identified significant differences among men without any disorder, those with benign lesions, and those with laryngeal cancer. Interestingly, no informative acoustic features were found among women in this study. Researchers suggest that a larger dataset may reveal such differences in the future. They concluded that variations in the harmonic-to-noise ratio could be useful for monitoring vocal fold lesions' progression and detecting early-stage laryngeal cancer in men. Dr. Jenkins stated: "Our results suggest that ethically sourced, large datasets like Bridge2AI‑Voice could soon help make our voice a practical biomarker for cancer risk." The next step involves training AI models on more extensive datasets labeled by professionals and testing their effectiveness across genders. He added, “To move from this study to an AI tool that recognizes vocal fold lesions, we would train models using an even larger dataset of voice recordings.” Voice-based health tools are already being tested; with further data collection and clinical validation efforts underway, similar detection tools might enter pilot testing within a couple of years.

China Unveils Revolutionary Plant That Turns Trash Into Treasure Without Sorting
A new facility in Jieyang, in China’s Guangdong province, is taking on one of the toughest challenges in the fight against plastic pollution: recycling lower-grade plastics without sorting them first. The plant, which can process 200,000 tons of plastic annually, uses a “one-step” deep catalytic cracking process to turn mixed scrap plastics directly into high-value chemical raw materials. That means complex or contaminated plastics that typically can’t be recycled through traditional methods can now be broken down and reused. “Through deep catalytic cracking, low-value mixed scrap plastics are directly converted into high value-added chemical raw materials… which will effectively solve the problem of plastic pollution and achieve high-value recycling and utilization,” Wang Shaole, deputy Party secretary of Jieyang, told China Daily. The government has pledged full support for the project, with future phases aiming to recycle more than three million tons of scrap plastic each year. Officials say the plant will also help reduce China’s dependence on imported crude oil by creating a domestic source of chemical feedstocks. The breakthrough could be significant in a world where traditional recycling leaves much plastic behind. In the United States, for example, only about 21 percent of household plastics are recycled, with the rest going to landfills. Sorting is expensive and time-consuming, and many plastics, especially multi-layer packaging and certain consumer goods, are nearly impossible to recycle with current technology. Plastic pollution is more than just a waste problem. Microplastics have been found in oceans, soil, food, and drinking water, and have been linked to health issues including reproductive problems, dementia, and cancer. Wang said the project represents “Guangdong’s wisdom and Chinese solutions” for building a global green circular economy. While large-scale recycling is key, experts stress that reducing everyday plastic use remains just as important, from switching to reusable containers to choosing plastic-free packaging. If the Jieyang plant’s model proves successful, it could provide a template for tackling the 44 million metric tons of plastic waste generated annually by the U.S., and the far larger total produced worldwide.

A Stranger's Heroic Act Sparked a Viral Hunt: Family Reunites with 'Angel' Who Saved Their Son
In late July, a family vacation to Kalaloch Beach in Olympic National Park turned into a dramatic rescue operation for the Borngrebe family from Nebraska. Ethan Borngrebe, 18, was climbing a rock face when he fell more than two meters and became trapped under a 68-kilogram piece of boulder. Ethan's parents, Kristina and Kurt Borngrebe, faced the harrowing sight of their son injured on the rocks. They had no cell service to call for help. "My first thought was, I'd rather have a paralyzed son who is alive than a dead one," Kurt told NBC affiliate KING. As panic loomed, Jacob, a stranger with perfect timing, appeared on the scene. According to Kristina's Facebook post, Jacob advised them not to move Ethan and provided ice for his finger while they waited for emergency responders. He stayed with them for two hours until help arrived. Photos from that day show Ethan strapped onto a stretcher with his head stabilized before being airlifted by helicopter to Seattle, more than 320 kilometers away. "I just reached out with tears in my eyes and said, 'Thank you,'" Kurt recalled saying to Jacob as they parted ways. Kristina later shared updates on social media about Ethan's recovery. Remarkably, he suffered no internal injuries despite the severity of the accident. While he underwent reconstructive surgery on his hand due to broken fingers and received stitches for a thigh laceration, doctors expect him to make a full recovery. The Borngrebes wanted to thank Jacob personally but only knew his first name and that he was from the Czech Republic. Kristina posted an appeal on Facebook seeking information about him. "My family and I can't decide if you are an angel or not," she wrote in gratitude for his assistance. After their story went viral online, Kristina announced they successfully found Jacob through social media connections and spoke with him over the phone; she described feeling "so blessed" by this resolution.

Hubble Captures Breathtaking Image of Cosmic 'Spider' Weaving Stars 160,000 Light-Years Away
The Hubble Space Telescope has released a vivid new image of the Tarantula Nebula, the largest and brightest stellar nursery in the Large Magellanic Cloud — a dwarf galaxy orbiting the Milky Way. Located about 160,000 light-years away in the constellations Dorado and Mensa, the nebula is home to some of the most massive known stars, with some tipping the scales at up to 200 times the mass of our Sun. Hubble’s latest snapshot focuses on the nebula’s fringes, near the super star cluster R136. This region hosts rare Wolf–Rayet stars — massive, hot stars that have blown away their hydrogen envelopes and are blasting their surroundings with intense stellar winds, reshaping the dusty clouds around them. Astronomers are studying these processes using an observing program called Scylla, named after the monster from Greek mythology. Scylla examines how dust and gas behave around these stars, and works in tandem with ULLYSES, another Hubble project building a vast ultraviolet library of young stars in both the Large and Small Magellanic Clouds.

Australian Parrots Wow Scientists with 30 Dance Moves, Including 17 Never Seen Before
When a catchy tune hits, most of us can't help but start moving. Interestingly, it's not just humans who feel the beat. Parrots, particularly cockatoos, have been seen getting their groove on too. A recent study has shown that these birds have an impressive repertoire of dance moves. Zoologist Natasha Lubke and colleagues at Charles Sturt University found that cockatoos can perform up to 30 distinct dance moves. These include head banging, sidestepping, body rolls, half-turns, and a move called 'fluff.' What’s surprising is that 17 of these moves were previously unknown to science. Researchers came across these moves by analyzing 45 social media videos featuring cockatoos dancing to music. They also observed six cockatoos at the Wagga Wagga Zoo in Australia. Regardless of whether they were played music or just ambient sounds like podcasts, these birds kept dancing. "We conclude that dance behavior in cockatoos is composed of a wide range of different movements," says Lubke. The team notes that further research could help determine if music might be used as a form of environmental enrichment for captive birds. One standout bird in the study had a particularly unique style with 17 solo moves not seen in other birds. The rest expressed themselves through various combinations of the identified 30 moves. Why do cockatoos dance? The researchers suggest it might be linked to courtship rituals adapted for entertainment purposes. Ethologist Rafael Freire from Charles Sturt University adds, "The similarities with human dancing make it hard to argue against well-developed cognitive and emotional processes in parrots." Freire believes playing music for parrots might improve their welfare as it seems to engage them cognitively and emotionally. The findings highlight how complex and fascinating animal behaviors can be, showcasing parallels between human and avian expressions through dance. This research was published in PLOS One.

Your Hair Could Be the Secret to Healthier Teeth, Thanks to a Surprising Scientific Breakthrough
Could your next trip to the dentist involve a product made from your own hair? It might sound like science fiction, but researchers at King's College London have developed a novel toothpaste using keratin—yes, the same protein found in hair and skin—that could revolutionize dental care. The study published in Advanced Healthcare Materials explores how keratin can repair tooth enamel and prevent early decay. When keratin interacts with minerals in saliva, it creates a protective coating that mimics natural enamel. This innovative approach offers a more sustainable alternative to traditional dental treatments. Sara Gamea, PhD researcher at KCL and first author of the study, explained, "Keratin offers a transformative alternative to current dental treatments." She highlighted its eco-friendly nature since it's derived from biological waste materials like hair and skin. This eliminates the need for traditional plastic resins often used in dentistry, which are less durable and potentially toxic. In their research, scientists extracted keratin from wool. When applied to teeth, keratin forms an organized scaffold that attracts calcium and phosphate ions over time. This leads to the formation of an enamel-like layer around the tooth. Such advancements could address common issues like enamel erosion caused by acidic foods, drinks, poor oral hygiene, and aging—all contributors to tooth sensitivity and decay. Dr. Sherif Elsharkawy, senior author of the study and consultant in prosthodontics at KCL, pointed out a significant problem: "Unlike bones and hair, enamel does not regenerate; once it is lost, it's gone forever." He emphasized how biotechnology now allows us to restore biological function using materials already present in our bodies. The implications of this research are promising. If further developed with industry partnerships, this keratin-based technology could lead to stronger teeth simply by utilizing something as commonplace as human hair.
