55-million-year-old fossil bird shows how trogons evolved their unusual feet
A fossil of Daniatrogon kochi, discovered in Denmark, provides insights into the evolution of trogon feet. Researchers found that the trogons' unique foot morphology developed gradually over time. The fossil also shows changes in the shape of their beaks, which were narrower than those of modern species. Additionally, early trogoniforms displayed more varied beak and foot shapes, indicating a diverse ecology.
Rice husk ash could make asphalt more resistant to high-temperature damage
Rice husk ash from rice mills has been shown to improve the properties of asphalt mixtures. The incorporation of varying ash amounts led to increased stiffness and higher resistance to permanent deformation. Higher ash content resulted in better performance at elevated temperatures but raised concerns about workability and low-temperature brittleness. Research indicates a trade-off between performance benefits and risks associated with increased ash amounts.
She found a baby raccoon on her ship; 7 years later, her Mississippi rescue has 76 orphaned kits
In Pass Christian, Mississippi, a wildlife center dedicates its efforts to training orphaned raccoon kits for their return to the wild. Through engaging, hands-on methods, staff members equip these young raccoons with essential survival techniques, such as foraging, swimming, and evading dangers. After around six months of training, the young raccoons are released back into their natural forest environments, significantly improving their chances of thriving in the wild.
MIT’s artificial reef helped a shrinking Maldives beach grow 90 feet and double in size
In a bold move against beach erosion, a Marriott resort in the Maldives is pioneering the use of artificial reefs. This project involves the careful placement of concrete blocks to enhance sand accumulation while simultaneously fostering local marine ecosystems. Via advanced satellite and ocean current data, Coastal Assembly identifies optimal reef locations, illustrating a transformative trend in sustainable coastal management practices worldwide.
Illinois is starting a roughly $15 million restoration of 794 acres at Dutch Gap Forest Preserve
In a groundbreaking move, Illinois officials are launching a robust ecological restoration project at Dutch Gap Forest Preserve with a budget of $15 million. The plan encompasses the rejuvenation of approximately 800 acres of land, focusing on eliminating agricultural drainage systems while revitalizing wetlands, streams, and prairies. Local support will enhance the federally funded project, with future plans to develop public trails following habitat stabilization.
Giant’s Causeway removes 20kg of lucky coins as the tradition threatens its fragile rocks
Visitors at Northern Ireland's Giant's Causeway have been causing harm by placing coins in its rock formations. The National Trust recently removed over 20 kilos of coins due to the damage they caused. Experts highlighted that oxidization of the coins led to the disintegration of the ancient basalt columns. New measures have been implemented, including signs and donation boxes for visitors.
Western snowy plovers return to California beach after 40 years as 212 birds are released since 2016
Western snowy plovers have returned to nesting at California’s Coal Oil Point Reserve after about 40 years. A conservation programme involving the Santa Barbara Zoo, UC Santa Barbara and the US Fish and Wildlife Service has released 212 birds since 2016. This year, 11 released plovers were fitted with radio and Bluetooth tracking devices to monitor their movements and survival.
Two bizarre new sea spiders found in Salish Sea, with hairy legs and debris-covered bodies
Scientists have identified two new sea spider species in the Salish Sea, nearly 100 years after the last new species was formally described there. One has hairy legs and red eyes and can groom itself with comb-like appendages. The other often carries debris and tiny parasites on its body. Researchers say more species may remain undocumented.
Two mountain marmots found in California cities were released in the wild near Lake Tahoe
Two yellow-bellied marmots were separately found far from their mountain habitat in San Francisco and Antioch in September. Wildlife rescuers believe the animals may have travelled inside vehicles from the Sierra Nevada or Lake Tahoe. After 18 days, both were released nearly 7,800 feet up near Lake Tahoe, while the cases highlighted the risk of marmots entering vehicles.
Archaeologists risked their lives to save 30,000 treasures from ISIS terrorists
In a remarkable feat illustrating tenacity and dedication, Syrian archaeologists embarked on a dangerous mission in 2014-2015 to salvage around 30,000 artifacts from the Deir ez-Zor Museum amidst the intense conflict with ISIS. Led by Professor Maamoun Abdulkarim, the operation faced significant challenges yet underscored the urgency of preserving Syria's cultural heritage and collective memory, reinforcing the crucial role historical artifacts play during times of crisis.
Scented Cleaners Create Nanoparticles: Purdue study flags hidden indoor risk; trillions of particles form during routine cleaning
A study conducted at Purdue University reveals that scented cleaning products release compounds that react with indoor ozone, leading to the quick formation of ultrafine particles that may diminish air quality. During cleaning in confined areas, these particles can accumulate significantly. While maintaining cleanliness is essential, it is wise to minimize exposure to chemical byproducts through methods like opting for fragrance-free alternatives and ensuring adequate ventilation.
Vivien He developed a device that detects earthquake signals and sends warnings through alarms
Vivien He has created an innovative IoT device called Qube, retailing for under $100. This device specializes in detecting earthquakes and alerts users through alarms or text messages. After a nine-month trial, it successfully identified quakes greater than M 3.0 in the Los Angeles region. The data collected indicated a reliable correlation between ground movements and quake magnitudes, underscoring the viability of affordable earthquake warning solutions in cities.
In 1993, a project set out to reconnect wildlife habitat from Yellowstone to Canada's Yukon
The Yellowstone to Yukon Conservation Initiative is proudly nominated for Prince William's Earthshot Prize in 2026. This groundbreaking effort aims to reinstate a vital 3,400-kilometre wildlife corridor through the majestic Rocky Mountains. Achieving over 200 wildlife crossings and safeguarding around 24 million hectares, Indigenous involvement is key to strengthening conservation practices here. Looking forward, the initiative hopes to secure an extra 20 million hectares by 2030.
