A comprehensive mapping of biofluorescence across 459 fish species reveals its ancient origins in eels and subsequent independent evolution over 100 times. Coral reefs significantly accelerate this trait's development, with reef-dwelling species acquiring it ten times faster. The research highlights the potential of biofluorescence as a species-specific signaling system and a valuable tool for taxonomic research.
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 new COVID-19 variant, NB.1.8.1 or "Nimbus," is spreading globally, causing painful sore throats, dubbed "razor blade throat." Primarily affecting the eastern Mediterranean, Southeast Asia, and western Pacific regions, it's been detected in the US. While some Western Pacific countries report increased cases and hospitalizations, current vaccines remain effective, and the WHO considers the public health risk low.
Group Captain Subhanshu Shukla will carry a mission badge designed by Manish Tripathi on the Axiom-4 mission, symbolizing India's space ambitions and cultural heritage. The emblem, a fusion of tradition and technology, features elements like the Gaganyaan icon, Aryabhata satellite, Jantar Mantar observatory, and India's map, representing the nation's journey in space exploration.
SpaceX successfully launched 26 more Starlink satellites into low Earth orbit from California, expanding its global broadband network. The Falcon 9 rocket, on its third flight, deployed the satellites as part of the Group 15-9 mission. The booster landed successfully on a droneship, ensuring its reuse for future launches, supporting SpaceX's goal of cost-effective space access.
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.
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 new study reveals that ancient Homo sapiens possessed a unique adaptability, thriving in diverse and challenging environments across Africa before their major dispersal around 50,000 years ago. This "ecological flexibility," as termed by researcher Emily Hallett, enabled them to inhabit rainforests, deserts, and more.
Asteroid 2024 YR4, though not an Earth threat, now poses a collision risk to the Moon. Scientists estimate a 4.3% chance of impact, potentially ejecting 100 million kilograms of lunar debris into space. This debris could endanger satellites in low Earth orbit, crucial for communication, GPS, and climate monitoring, necessitating international attention and preparedness.
