How Ocean Acidification Could Cause Dental Problems For Sharks
Sharks are the most feared predators in the sea, and their survival hinges on fearsome teeth that regrow throughout their lives. But changes in the ocean's chemistry could put those weapons at risk.

Researchers Develop Wetsuits That Protect Against Shark Bites And Stings
Australian researchers have tested new bite-resistant wetsuits that minimize injuries from shark bites. The materials, made with chain mail, Kevlar, and nanofibers, help reduce bleeding and improve safety for surfers and divers. The innovation marks a step forward in shark bite protection without limiting flexibility underwater.

NASA’s Curiosity Rover Spots Ancient Coral-Like Rock on Mars
On July 24, 2025, NASA’s Curiosity Mars rover captured an image of a small, coral-shaped rock in Gale Crater using its ChemCam Remote Micro Imager. The light-colored, 1-inch (2.5 cm) formation likely formed billions of years ago when mineral-rich water seeped into tiny fractures in the rock, leaving behind hardened mineral veins after evaporation...

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...

Australia's Great Barrier Reef Records Largest Annual Coral Loss In 4 Decades
The Great Barrier Reef has experienced its greatest annual loss of live coral across most of its expanse in four decades of record-keeping, Australian authorities say.

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...

Earth’s Oceans Enter Danger Zone Due to Rising Acidification, New Study Warns
A new 2025 study published in Global Change Biology shows Earth’s oceans may have entered a dangerous acidification zone in 2020. As CO₂ emissions increase, marine ecosystems are degrading, threatening biodiversity, food security, and coastal economies. Scientists call it a ticking time bomb for the environment and society.

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...
