Whales And Dolphins Frequently Hang Out With Each Other: Study
As the annual humpback whale migration is underway with thousands of whales passing by the Australian coast, there are reports of dolphins joining the mass movement.

Greenland's Melting Glaciers Feed Ocean Life, Study Finds
A new NASA-led study reveals that Greenland’s melting glaciers are fueling life in the Arctic Ocean. Each summer, massive freshwater plumes from glaciers like Jakobshavn drag deep-sea nutrients upward, boosting phytoplankton growth by up to 40%. These microscopic organisms form the base of the marine food web and play a key role in carbon absorpt...

5 Arms, No Eyes, No Heart: DNA Revealed Weird Deep-Sea Brittle Star Journey
You may have read that the deep sea is a very different environment from the land and shallow water. There is no light, it is very cold, and the pressure of all the water above is immense.

AI Designs Ocean Gliders Inspired by Sea Creatures to Boost Underwater Research Efficiency
Researchers at MIT and the University of Wisconsin have developed AI-designed underwater gliders inspired by marine animals. The new shapes, generated using machine learning, move more efficiently underwater than traditional torpedo designs. This innovation could greatly improve climate and ocean monitoring by enabling better performance, energy sa...

Hundreds Of New Giant Viruses Discovered In Global Waters: Study
The study identified 230 new giant viruses and 530 novel functional proteins, shedding light on their interactions with marine microbes and potential biotechnological applications.

Scientists Discover Clicking Sounds in Rig Sharks for the First Time
Sharks were long thought to be silent, but a surprising new study reveals that rig sharks can make clicking sounds when handled. Evolutionary biologist Carolin Nieder first discovered the clicks by accident during lab tests. These sounds—likely produced by snapping their flat teeth—occurred most often during initial handling, suggesting a stres...

Faces You Hear? Dolphin 'Signature Whistles' Might Be What Facial Expressions Are To Us
Bottlenose dolphins live in complex societies where each animal has a small number of closely connected individuals and a larger number of looser associates (not dissimilar to our own social networks).

New Analysis Weakens Claims of Life on Distant Exoplanet K2-18b
A new study led by University of Chicago researchers has reanalyzed James Webb Space Telescope data and found weaker evidence for potential biosignatures on exoplanet K2-18b. Earlier reports had suggested the presence of dimethyl sulfide (DMS), a chemical associated with marine life on Earth. However, the latest analysis reveals that the signals ar...

Strange New Worm Found Off Spain’s Coast Can Shrinks to One-Fifth Its Size
Scientists have discovered Pararosa vigarae, a new genus and species of ribbon worm, off the Northwest coast of Spain. Nicknamed the accordion worm for its ability to shrink to one-fifth its normal size, it was found 30 meters deep in RÃa de Arosa. Traditional taxonomy methods failed to classify the species due to limited external features, so res...

Cuttlefish May Communicate Using Tentacle Waves, Study Finds
Cuttlefish are known to use more than color-changing and posture to communicate — new research suggests they wave their tentacles to send signals. Scientists at École Normale Supérieure observed four distinct wave patterns and found cuttlefish respond both visually and through water vibrations. With plans to use AI and robotics to decode these ...

Study Finds Grey Seals Can Track Blood Oxygen to Prevent Drowning
A study has revealed that grey seals can monitor their blood oxygen levels to determine when they need to surface for air. Researchers tested seals in controlled environments, exposing them to different oxygen and carbon dioxide levels. The findings confirmed that higher oxygen led to longer dives, while reduced oxygen shortened them. Surprisingly,...

Antarctic Ice Melt Weakens Strongest Ocean Current, Disrupting Global Circulation
The Antarctic Circumpolar Current, the planet’s most powerful ocean circulation system, could slow by 20 percent by 2050 due to melting Antarctic ice. Researchers suggest that the influx of fresh, cold water is disrupting convection, altering global ocean density. A weaker current may allow warm water to reach Antarctica, accelerating ice loss an...

Fossil Evidence Shows Plants Survived the End-Permian Mass Extinction in China
Fossils discovered in China indicate that the End-Permian mass extinction, which wiped out 80% of life on Earth, may not have been as devastating for plants as previously thought. Researchers found evidence of gymnosperm forests and ferns in rock layers from this period, suggesting that some ecosystems remained intact. This discovery challenges ass...

World’s Largest Iceberg A23a Grounds Near South Georgia, Raising Wildlife and Environmental Concerns
The world’s largest iceberg, A23a, has run aground near South Georgia, a key wildlife haven. Scientists are monitoring its impact on marine life, particularly on penguins and seals, as it could disrupt feeding routes. Some experts suggest the iceberg may also enhance ocean productivity by releasing nutrients. If it fragments, it may pose risks to...

3 Billion-Year-Old Beach Buried On Mars Discovered By Scientists
Data from Zhurong provide an unprecedented look into rocks buried near a proposed shoreline billions of years old. The researchers claim to have found beach deposits from an ancient Martian ocean.
