In a remarkable study, researchers observed a male common octopus (_Octopus vulgaris_) off the coast of Ibiza, Spain, which had survived a predator attack that resulted in the loss of three arms. During the regrowth process, one arm bifurcated, giving the octopus a total of nine limbs. Over several months, scientists documented the octopus's behavior, categorizing its arm usage into "safe" and "risky" behaviors. They found that the most utilized limbs were L1 and the bifurcated R1a, while more severely injured arms were less likely to be used in risky situations, suggesting the octopus may possess a form of pain memory linked to past injuries. The study highlights the adaptability of octopuses and their ability to repurpose regrown limbs, shedding light on their complex behavior and survival strategies. The findings are detailed in the journal *Animals*. 
Published: Jun 04 2025, 7 ameznews.inAs the BA.5 subvariant of COVID-19 surges globally, scientists are noting a potential new symptom: night sweats. This variant, a sibling of Omicron, now accounts for approximately 65% of cases in the US and is similarly prevalent in the UK. Professor Luke O’Neill from Trinity College Dublin highlighted that night sweats may arise from genetic changes in the virus and the immune system's response, suggesting a shift in symptomatology. While BA.5 appears to cause less severe illness than earlier variants like Delta, its ability to reinfect individuals raises concerns. Current data from the ZOE COVID Study app indicates that common symptoms among vaccinated individuals now include runny nose, headache, and sore throat, while traditional symptoms such as loss of smell and fever have become less frequent. O’Neill emphasized the importance of vaccination to mitigate severe outcomes from the infection.
Published: Jun 05 2025, 11 pmeznews.inA submarine volcano off the West Coast of the US, the Axial Seamount, is showing signs of an impending eruption, with geologists predicting a potential event between July 2024 and the end of 2025. Located approximately 480 kilometers from Oregon, the seamount last erupted in 2015, releasing lava and debris across a vast area. The Ocean Observatory Initiative has been monitoring the site since 2016, providing livestream footage of its unique marine life, including hot spring deposits and various organisms. While the volcano is building pressure, it poses no threat to human life, as it is unlikely to trigger tsunamis or earthquakes. However, when it does erupt, it could significantly alter local ecosystems, covering the seafloor with fresh lava and impacting marine habitats. Livestreams of the seamount will be available for viewers at specific times throughout the day.
Published: Jun 05 2025, 9 pmeznews.inFor the first time, solar astronomers have captured unprecedented images of striations on the Sun's surface, revealing intricate "magnetic curtains" at a resolution of just 20 kilometers (12.4 miles) using the Daniel K. Inouye Solar Telescope in Hawai’i. These stripe-like features, which form at the edges of solar granules, are influenced by surrounding magnetic fields, causing variations in brightness and color. Lead author Dr. David Kuridze from the National Solar Observatory described these striations as "fingerprints" of fine-scale magnetic field variations. The Sun's magnetic field can be thousands of times stronger than Earth's, and these findings enhance our understanding of magnetism in astrophysical contexts. The Inouye telescope's capabilities have led to significant advancements in solar research, underscoring its role in studying the small-scale physics that drive space weather events affecting technology on Earth. The study is published in The Astrophysical Journal Letters.
Published: Jun 06 2025, 5 ameznews.inBill Gates has warned that the world is unprepared for the next potential pandemic, which could mirror the devastating 1918 influenza outbreak, potentially killing 30 million people within six months. Speaking at a discussion on epidemics, Gates emphasized that the next disease might not even be a flu but a novel pathogen, urging global leaders to approach pandemic preparedness with the same urgency as military threats. He highlighted the increasing likelihood of new diseases emerging due to population growth and environmental encroachment, as well as the risk of bioweapons being developed by non-state actors. While acknowledging advancements in antiviral treatments and the pursuit of a universal flu vaccine, Gates stressed the need for improved rapid diagnosis and better coordination between governments and the private sector to effectively combat emerging health threats. He remains optimistic that with concerted effort, humanity can enhance its pandemic response capabilities.
Published: Jun 04 2025, 2 pmeznews.inA remarkable image captured during NASA's LADEE spacecraft launch on September 7, 2013, features an unexpected photobomber: a frog. The photo, taken by a sound-activated camera at Virginia's Wallops Flight Facility, shows the amphibian soaring through the air as the rocket ascends, although the frog's fate remains uncertain. The LADEE mission aimed to study the lunar atmosphere and the effects of lunar dust, marking a significant step in space exploration. Wallops, the oldest continuous rocket launch site in the U.S., has been operational since 1945 and coexists with local wildlife, highlighting a unique relationship between advanced space technology and nature. For instance, NASA's Kennedy Space Center in Florida borders the Merritt Island National Wildlife Refuge, home to diverse species. This unusual coexistence underscores the potential for protected habitats amidst the noise of rocket launches, proving that even in the realm of space exploration, life finds a way.
Published: Jun 06 2025, 6 ameznews.inIn 2001, French snowboarder Marco Siffredi made history by becoming the first person to snowboard down Mount Everest after summiting the peak at 8,848 meters. Initially planning to descend via the Hornbein Couloir, he switched to the Norton Couloir due to insufficient snow. Siffredi's record was later challenged by Stefan Gatt, who reached the summit first but had to complete part of his descent on foot due to adverse conditions. In 2002, Siffredi returned to attempt the Hornbein Couloir, known for its steep slopes of 45 to 55 degrees. Despite warnings from his team of sherpas about deteriorating weather, he began his descent late in the day with one oxygen tank. He was never seen again, and while avalanches and sheer drops posed significant risks, his body has never been recovered. Over 310 climbers have died on Everest, making it the mountain with the highest absolute death count, though its fatality rate is lower than some other peaks.
Published: Jun 06 2025, 12 ameznews.inGreat white sharks (_Carcharodon carcharias_), renowned apex predators, are rarely seen in aquariums due to significant challenges in captivity. Despite their size not being the sole issue—since orcas are kept in captivity—great whites have a history of failing to thrive in artificial environments. Notable attempts include a 2016 effort at Japan's Okinawa Churaumi Aquarium, where a shark died after just three days, and earlier attempts at Marineland and SeaWorld, which also ended in failure. The Monterey Bay Aquarium managed to keep one alive for several months in 2004, but this remains an exception. Key factors contributing to their poor performance in captivity include their specific dietary needs, the necessity to swim continuously for oxygen, and the overwhelming stimuli of a tank environment. Additionally, changing public perceptions about marine life in captivity, influenced by documentaries like _Blackfish_, suggest that a live great white exhibition would no longer attract the same interest as in the past.
Published: Jun 03 2025, 4 pmeznews.inResearchers have uncovered a groundbreaking link between maternal iron levels and sex determination in embryos, revealing that low iron concentrations in pregnant female mice can lead to male embryos developing ovaries, regardless of their genetic makeup. Traditionally, sex in mammals is believed to be determined by genetics at fertilization, with the SRY gene on the Y chromosome guiding male development. However, this study, published in *Nature*, challenges that notion by demonstrating that iron deficiency can inactivate the SRY gene, resulting in atypical sexual development. In experiments, four out of 72 XY embryos from iron-deficient mothers developed two ovaries, while others exhibited mixed reproductive structures. This research suggests that environmental factors, such as iron levels, play a significant role in sexual differentiation, potentially reshaping our understanding of sex determination in mammals, although further studies are needed to explore implications for humans.
Published: Jun 05 2025, 8 pmeznews.inIn a surprising turn of events, the Asian small-clawed otter (_Aonyx cinereus_), previously thought to be extinct in Nepal since its last sighting in 1839, has been rediscovered. A young otter was spotted in November 2024 at the confluence of the Rangun and Puntara rivers in Dadeldhura District, prompting wildlife researchers to confirm its identity after forest officers provided photographs and videos. This sighting marks the first official documentation of the species in 185 years, ending long-held concerns about its extinction in the region. However, experts warn that the otter faces numerous threats, including river pollution, unsustainable fishing, and habitat degradation. As Nepal develops a national otter conservation plan, officials stress the importance of incorporating the small-clawed otter into conservation policies to ensure its survival. The findings were published in the IUCN/SSC Otter Specialist Group Bulletin, highlighting the need for urgent conservation efforts.
Published: Jun 03 2025, 9 pmeznews.inScientists have confirmed a remarkable phenomenon involving the nematode worm _Caenorhabditis elegans_, which forms coordinated towers in nature, functioning as a superorganism. This discovery, made by researchers at the Max Planck Institute of Animal Behavior, marks the first documentation of such behavior occurring in the wild, as previous observations were limited to artificial settings. The towers, composed exclusively of worms in the dauer larval stage, can respond to touch and attach to passing objects, enabling them to bridge gaps that individual worms cannot cross. Senior author Dr. Serena Ding expressed amazement at the coherent structure and collective behavior of the worms. The team successfully recreated these towers in the lab, revealing their ability to stick together and perform complex tasks. Future research will explore the evolutionary and ecological implications of this behavior, leveraging the genetic tools available for _C. elegans_ to investigate the underlying mechanisms.
