Chang’e-6 soil reveals metallic iron in lunar samples; it may preserve clues to Moon’s lost magnetic field
Recent analysis of lunar soil samples returned by China's Chang’e-6 mission revealed a unique form of iron. This iron, γ-Fe, exhibits exceptional magnetic properties, which could provide insights into the Moon's ancient magnetic field. Researchers suggest that extreme impacts on the lunar surface caused the formation and preservation of this unusual iron. The findings could enhance our understanding of the Moon's geological history and its evolution over time.
New dating rewrites history of Oklahoma meteor crater
Researchers from the University of Texas at Austin have traced the Ames meteor impact to approximately 370 million years ago, presenting a significant revision to the previously accepted estimate of 467 million years. This research connects the impact with the Frasnian-Famennian mass extinction event, employing zircon crystals to establish a more precise timeline, thus providing deeper insights into pivotal moments in Earth's geological history.
In 1987, ancient glass sponge reefs were found alive off Canada's Pacific coast after 40 million years
In 1987, Canadian scientists discovered ancient glass sponge reefs alive in British Columbia’s Hecate Strait, overturning the belief that these reef-building animals had vanished 40 million years ago. More than 9,000 years old, the reefs survive today in Hecate Strait, Queen Charlotte Sound and Howe Sound, creating a rare underwater ecosystem often called the “Sea of Glass.”
Astronomers find ‘phoenix planet’ born from ashes of a dying star
A team of astronomers has discovered a second-generation planet orbiting a white dwarf named HS 0209+0832. This planet formed from the material that the white dwarf expelled during its death. The atmosphere of the white dwarf contains heavy elements such as zinc, copper, and niobium. This discovery could change the way astronomers search for similar planets around dead stars.
Two sisters turned their childhood love of the ocean into a 65-foot research yacht
Angela Rosenberg and her sister took a significant step by establishing the ANGARI Foundation to fill the void in marine science education. Collaborating with Florida International University, they facilitate student participation in real-world expeditions aboard the research vessel R/V ANGARI. These experiences, including shark tagging and plankton exploration, aim to ignite students' passion for marine science, fostering a connection between youth and the ocean.
Scientists found a new magnetic mineral in Chang’e-6 Moon samples, preserved inside impact-glass particles
A groundbreaking discovery by researchers has unveiled a new magnetic mineral, γ-Fe, found in lunar samples from the Chang'e-6 mission. This remarkable find sheds light on the ancient magnetic environment of the Moon, now long lost. Detailed analysis of tiny iron particles within lunar impact glasses reveals that γ-Fe can maintain stable magnetic signals, potentially serving as a record of the Moon's magnetic history.
Burmese pythons and invasive plants reshape Everglades as native mammals decline by about 90%
The Everglades is grappling with the impacts of non-native species that are wreaking havoc on its native ecosystems. Invasive plants such as Melaleuca and Brazilian pepper are changing fire patterns and overshadowing indigenous flora. Moreover, the Burmese python is contributing to alarming drops in native mammal numbers. Ongoing management strategies are being implemented to combat these invaders, highlighting the urgent need for effective ecological restoration to safeguard this unique environment.
Montana student compares banana and plantain starch to make stronger bioplastic
Rye Lynn Rost, a seventh grader from Montana, created bioplastics using starch from plantains and bananas. She discovered that plantains have more starch and higher tensile strength than bananas. Rye performed tests by comparing both bioplastics against plastic parafilm to evaluate their strength. Her project focuses on making sustainable bioplastics that are durable in environmental conditions over time.
13 insects in 99-million-year-old amber reveal new species with mouthpart nearly twice its body length
A remarkable new insect species, Cretodorus noonoo, has been unearthed from 99 million-year-old amber found in Myanmar. This intriguing species is linked to the Neazoniidae family, renowned for its extraordinary mouthparts. These long and flexible adaptations reveal specialized feeding behaviors on tree sap. This discovery sheds light on the ecological interactions within Cretaceous forests, illustrating the diverse evolutionary strategies that shaped ancient ecosystems.
Ageing mice study finds why 'zombie cells' evade immune clearance and fuel inflammation
Researchers studying ageing in mice have found that a decline in chaperone-mediated autophagy (CMA), a cellular recycling process, helps “zombie cells” accumulate by weakening the immune system’s ability to clear them. Restoring CMA reduced senescent-cell buildup, inflammation and fibrosis in mice, pointing to a possible new approach to age-related diseases.
40 oyster reefs placed along Gandy's Beach in New Jersey to support live oysters and cut storm-wave
A New Jersey project that began installing 40 constructed oyster reefs along about 800 metres of Gandy’s Beach in 2015 recorded more than 800 live oysters per square metre during early monitoring. Researchers also found the reefs reduced storm-wave height by up to 51% under certain conditions, though seven years of monitoring showed continued elevation and vegetation loss at the site.
Meet Sartaj Singh Gandhi, the student who built a sensor to detect spoiled meat
Sartaj Singh Gandhi, a brilliant seventh grader, has innovatively developed a device that monitors the freshness of various meats by tracking ammonia gas released during decay. His research revealed that peak ammonia levels were detected on day six of testing turkey, chicken, pork, and beef. With plans to broaden the device's capabilities to other food types, Sartaj dreams of a future in cardiothoracic surgery.
