hydrothermal vents

Yellowstone's dynamic underground hydrothermal system remains a scientific enigma. Recent studies reveal a complex network of fluid pathways, but many processes are still not fully understood. Unpredictable geyser behavior is linked to shifting ground fractures, water availability, and pressure. New technologies are offering deeper insights into this constantly evolving geological marvel.

Ancient rocks in Quebec, dating back 3.77 billion years, may hold the oldest evidence of life. Microscopic tube-like structures and filaments, resembling modern microbes, were found alongside chemical signatures of biological activity. This suggests life emerged rapidly on early Earth, potentially thriving in hydrothermal vents, offering insights into life's origins and possibilities on other planets.

The ocean, though partially explored, defies expectations with phenomena like kilometer-long 'ghost tracks' on the seabed and sound waves trapped in SOFAR channels. Methane plumes erupt like underwater explosions, while hydrothermal vents 'breathe' mineral-rich fluids. Unexplained light displays and massive submarine landslides further challenge our understanding of this vast, mysterious realm.

Mount Uturuncu, a Bolivian volcano, is not on the brink of a massive eruption as previously feared. New research reveals its 'zombie' behaviour stems from migrating hydrothermal fluids and gases, not an imminent magma buildup. While still active and hot, this discovery reduces immediate eruption concerns, suggesting the volcano is expelling steam rather than preparing to explode.

Associate Professor Youhei Yamashita and grad student Yutaro Mori at Hokkaido University, along with Professor Hiroshi Ogawa at AORI, The University of Tokyo, have revealed conclusive evidence that hydrothermal vents are a previously unknown source of dissolved black carbon in the deep ocean. Their discoveries were published in the journal Science Advances.

Analysis of samples from the asteroid Ryugu has revealed all five nucleobases essential to DNA and RNA, strengthening evidence that life’s chemical building blocks are widespread in space. While not proof of extraterrestrial life, the finding suggests asteroids could have delivered key ingredients to early Earth, offering new insight into how life’s fundamental chemistry may emerge across the universe.

Life finds its way, even in total darkness at the deepest spot on Earth, scientists say after finding fields of bone-white clams clustering at hydrothermal vents in the western Pacific Ocean which lie as deep as 5,860 meters below the surface.

A massive hydrothermal field, Kunlun, has been discovered in the Pacific Ocean, exceeding the size of the Lost City. This unique ecosystem, teeming with life forms that thrive on chemosynthesis, offers a rare glimpse into conditions resembling early Earth. Researchers believe Kunlun's hydrogen-rich vents could hold vital clues to understanding the origins of life.

Scientists have discovered animal life thriving beneath the seafloor at a depth of 2,500 metres, challenging previous beliefs that only microorganisms could survive such environments. The study, near hydrothermal vents, revealed species like tubeworms and mussels. This finding suggests that complex lifeforms may exist deeper within Earth's crust, prompting further exploration and enhancing our understanding of marine biodiversity.

The article examines the origins of ocean salinity through processes like weathering, erosion, volcanic activity, and hydrothermal vents. It describes how minerals from rocks are transported to the sea via rivers and seafloor vents. The article also highlights the contribution of salt domes and marine life in maintaining ocean salinity levels over time.

Astrobiologist Laurie Barge and her team at NASA’s Jet Propulsion Laboratory in Pasadena, California, are working to recognize life on other planets by studying the origins of life on Earth. Their research focuses on how the building blocks of life form in hydrothermal vents on the ocean floor.

A Chinese submersible vessel has conducted its first deep dive in the Indian Ocean in search of rare metals.

A remarkable yellow worm, Paralvinella hessleri, thrives near boiling, toxic hydrothermal vents in the Pacific. This deep-sea dweller ingeniously converts deadly arsenic and sulphide into a golden mineral called orpiment, forming a natural shield. This unique adaptation allows the worm to flourish in an otherwise uninhabitable environment, showcasing nature's extraordinary chemical resilience.

Whale carcasses transform the deep sea into a vibrant ecosystem, offering a massive, decades-long feast for bizarre creatures. From hagfish and sharks stripping flesh to bone-eating worms and sulphur-loving microbes, these "whale falls" demonstrate nature's remarkable ability to create life from death, acting as crucial stepping stones for deep-sea species.

Europa, Jupiter's moon, offers tantalizing prospects for alien life with its subsurface ocean and active geological features. Recent discoveries include water plumes and potential hydrothermal vents, hinting at a habitat conducive to microbial life. The upcoming Europa Clipper mission aims to delve deeper, analyzing surface and atmospheric conditions to assess habitability. While definitive proof remains elusive, Europa continues to intrigue scientists and stoke humanity's quest for extraterrestrial life.

A newborn girl was rescued in a critical condition from the toilet of the female medicine ward of Bhima Bhoi Medical College and Hospital, Balangir, on Saturday morning. The baby was admitted to the Special Newborn Care Unit (SNCU) in the Mother and Child Hospital on the campus.

Patna University (PU) on Tuesday notified the revised payscales of teachers and non-teaching staff.

NCPOR scientists in Goa are exploring the Indian Ocean depths for rare minerals using advanced technology. The mission aims to discover valuable mineral deposits for commercial and strategic purposes.

India has begun an exploration for mineral deposits and precious metals like gold and silver in the Southern Indian Ocean.

Patna and some other districts in the state received moderate rainfall on Friday. The Indian Meteorological Department (IMD) has issued forecast for fairly widespread rainfall on Saturday as well.
