Researchers in Japan have developed a novel plastic that dissolves in seawater within hours, potentially mitigating microplastic pollution. Created from sodium hexametaphosphate and guanidinium ions, this durable, non-flammable plastic can be customized for various applications. Its rapid disintegration in saltwater and the recyclability of its components offer a promising solution to the global plastic crisis.
International Space Station astronauts celebrated with 'space sushi'. Jonny Kim shared the crew's creative meal on social media. They used rice, spam, fish, gochujang, and wasabi. Limited supplies didn't stop them. Astronauts taped surfaces to keep food from floating. The meal boosted morale and fostered connection. Social media users admired their resourcefulness and ingenuity.
Marine megafauna, including whales and sharks, face increasing threats from human activities, impacting ocean ecosystems. A recent study by WHOI and ANU tracked these species to identify critical areas for conservation. The research emphasizes the need for expanded marine protected areas and mitigation strategies to alleviate human pressure and ensure the survival of these vital ocean giants.
A recent study of 514-million-year-old archaeocyathid reefs in Nevada reveals that early reefs didn't consistently boost biodiversity like modern coral reefs. Researchers found inconsistent patterns of marine life around these ancient reefs, largely dependent on localized conditions. This discovery challenges assumptions about reef ecosystems and offers insights into the evolution of marine systems.
Birds undertake remarkable migrations, utilizing a complex navigation system that combines familiar senses with extraordinary abilities. They rely on landmarks, the sun, stars, and even the Earth's magnetic fields to find their way. Researchers are unraveling these mechanisms, potentially aiding conservation efforts by understanding the genetic basis of migratory routes.
Astronomers have observed thick, mineral-rich clouds, potentially containing iron, enveloping the young exoplanet YSES-1b, leading to the possibility of iron rain. The YSES-1 system, only a million years old, features two gas giants, offering a unique opportunity to study planet formation. Researchers are intrigued by the persistent dust disk around YSES-1b, challenging existing planet formation theories.
A 60-meter asteroid, 2024 YR4, has a 4.3% chance of hitting the Moon on December 22, 2032. NASA warns the impact could eject lunar debris towards Earth, endangering satellites and future lunar missions. Scientists estimate a significant portion of this debris could damage or disable satellites, potentially causing widespread communication and GPS failures.
Researchers discovered a hidden island near Rio Grande. The island has abundant rare earth elements. This finding could revolutionize green technology. Scientists believe the island was once part of a large tropical landmass. The site may hold evidence of past human habitation. Further research will explore the island's history and composition. This discovery could transform natural resource acquisition.
Nasa's Lunar Reconnaissance Orbiter has captured images of the crash site of ispace's lunar lander, Resilience, which impacted Mare Frigoris on the moon's far north. The images reveal a dark smudge and a faint halo of lunar dirt, marking the second failed landing attempt for the Tokyo-based company in two years.
A recent study reveals that fish, including rainbow trout, experience intense pain for several minutes when killed using common methods like air asphyxiation. This suffering extends beyond slaughter, with pre-slaughter stressors also contributing to their distress. Researchers suggest improved stunning methods and worker training to reduce fish suffering and promote more humane practices in fish farming.
