NASA's Crew-12 undocks from ISS, set to splash down off California after nearly eight months in space
NASA's SpaceX Crew-12 has undocked from the International Space Station and is on its way home. The mission included significant scientific investigations aimed at future Moon and Mars missions. Crew members participated in critical spacewalks, with Jessica Meir and Sophie Adenot completing important tasks outside the station. NASA is targeting a splashdown in the Pacific Ocean off the California coast on Thursday.
San Andreas and San Jacinto faults reach extreme stress as California’s ‘earthquake gate’ hits a 1,000-year high point
Recent research indicates elevated stress levels at Cajon Pass, affecting interactions between the San Andreas and San Jacinto faults. The stress is reportedly at its highest point in the last 1,000 years of observations. While this research does not predict a specific earthquake, it sheds light on how future ruptures may behave. Understanding the relationship between the fault segments could be vital for seismic hazard assessments.
In 2000, San Diego sank the 366-foot HMCS Yukon off Mission Beach; from 2015 to 2020, nine divers recorded 237 observations across 58 marine species
The HMCS Yukon, a Canadian warship, was intentionally sunk near Mission Beach to foster a new artificial reef. Initial research from 2004 indicated potential for marine life attraction, later enhanced by Ocean Sanctuaries' study utilizing advanced photography and AI for species identification. Results show the Yukon indeed nurtures a vibrant reef community, bolstering local biodiversity.
A massive jellyfish swarm clogged cooling-water filters at France’s Gravelines nuclear plant, forcing three reactors offline and cutting output at a fourth
A French nuclear facility faced major shutdowns as massive jellyfish invaded its cooling systems, resembling an incident from last year. This recurring issue points towards a concerning trend influenced by warmer ocean temperatures and overfishing, which are driving jellyfish numbers up globally. Power stations along coasts are increasingly vulnerable to these marine phenomena, and the evolving climate challenges nuclear energy requirements to adapt to shifting oceanic conditions.
2026 Super El Niño Forecast: What happens this winter could shock California, here's why
California anticipates a dangerous winter with record coastal sea levels. A rapidly strengthening El Niño threatens increased flooding and erosion along the shoreline. Higher seas could combine with large waves and winter storms for greater pressure. Beaches may lose their sand buffer, exposing infrastructure to powerful surf. Warmer Pacific waters also risk marine heatwaves and harmful algal blooms.
Built to hunt enemy submarines during World War II, this device later transformed our understanding of the seafloor
World War II fluxgate magnetometer: A World War II device found new scientific purpose after the war. Oceanographers refitted the fluxgate magnetometer for seafloor magnetic anomaly measurements. These measurements revealed symmetrical patterns on either side of mid-ocean ridges. The "magic profile" provided strong evidence for seafloor spreading and plate tectonics.

In 2023, San Diego researchers released bright pink dye into an estuary plume to study how runoff moves through breaking surf
Researchers dyed ocean water pink to track storm runoff at Torrey Pines. This experiment, called PiNC, used non-toxic dye released into Los Peñasquitos Lagoon. Drones and sensors helped scientists monitor the pink plume's movement and dispersal. The study aimed to understand how small waterways impact coastal water quality. This research highlights the unseen journey of pollutants after rainfall.
July 9 is the shortest day ever in history? Scientists call it 'unprecedented, big deal'
Earth is expected to spin faster in the coming weeks, leading to unusually short days. On July 9, 2025, Earth will experience one of the shortest days ever recorded, with similar events anticipated on July 22 and August 5, 2025. The Moon's position will influence Earth's rotation, shortening each day by 1.3 to 1.51 milliseconds.
You’re the centerpiece in a phenomenon not seen in 30 million years
Earth's atmosphere has surpassed 430 ppm of carbon dioxide in May 2025, a record high in millions of years, primarily due to human activities like burning fossil fuels. This alarming milestone drives extreme weather events and temperature increases. Scientists emphasize the urgent need to curb emissions to mitigate severe climate impacts and limit global warming as per the Paris Agreement.
Underwater volcano near US coast could blow this year, warn scientists after spotting massive swelling
An undersea volcano named Axial Seamount near Cannon Beach, Oregon, is expected to erupt in 2025. Scientists have detected significant ground inflation, indicating magma movement. The volcano has a history of eruptions in 1998, 2011, and 2015. Continuous monitoring with advanced technologies has led to this prediction, marking a breakthrough in volcanic science.
Legendary doom fish returns to California, believed to signal disaster; here's what's in store
In a recent development it has been known that the rare oarfish which is also known as the legendary doom fish and is hugely believed as a signal of disaster washed up on the beaches of California and the citizens are a bit scared.
Subglacial meltwater flowing beneath Antarctic glaciers could accelerate retreat, study finds
Researchers have found that subglacial discharge, or meltwater flowing out to sea from beneath Antarctic glaciers, could be causing glaciers to lose ice at a faster rate. This discharge raises the glaciers' contribution to sea-level rise by 15.7% by the year 2300. Current models do not take into account this mechanism, which suggests that current projections underestimate global sea-level rise. The study highlights the importance of reducing greenhouse gas emissions in order to mitigate the effects of climate change.
Sounds from missing Titanic submarine prove to be elusive as time runs out for search efforts
The Coast Guard reported that search teams discerned intermittent banging noises, occurring at 30-minute intervals. Nonetheless, Art Trembanis, a distinguished marine scientist from the University of Delaware, cautioned against prematurely ascribing these banging sounds to signs of life. He indicated that even such a pattern could conceivably emanate from an underwater instrument generating repetitive noise.
