Ocean life may have bounced back after the ‘Great Dying’
Marine ecosystems may have been back in action just a million years after the most severe extinction event known.

Sea life may suffer as plastic bits alter metals in water
This interplay between plastics and metals could affect how each affects the environment — and suggests opportunities for controlling their risks.

An ancient ichthyosaur graveyard may have been a breeding ground
Some 230 million years ago, huge dolphin-like reptiles appear to have gathered to breed in safe waters, just as many whales do today.
- Environment
Microplastic pollution aids viruses and prolongs their infectivity
The tiny plastic bits give these germs safe havens. That protection seems to increase as the plastic ages and breaks into ever smaller pieces.

Greenland’s inland ice is melting far faster than anyone thought
Inland melting of the Northeast Greenland Ice Stream is accelerating — and may contribute far more to sea level rise than earlier estimates suggested.

One 2022 tsunami may have been as tall as the Statue of Liberty
A massive volcanic eruption in the South Pacific, earlier this year, appears to have triggered one tsunami that was initially 90 meters (nearly 300 feet) tall.
- Animals
Whale sharks may be the world’s largest omnivores
Chemical clues in the sharks’ skin show that the animals eat and digest algae.

Night lights make even the seas bright
Light from coastal cities and offshore development may shine deep enough to disrupt tiny critters living dozens of meters (yards) below the surface.

Analyze This: Corals stash microplastics in their skeletons
Scientists have wondered where the ocean’s microplastic pollution ends up. Corals may trap about 1 percent of particles in tropical waters each year.

Orcas can take down the largest animal on the planet
For the first time, scientists observed that orcas can kill blue whales by using the same hunting techniques that have worked on other large whales.

Scientists Say: Pollution
Pollution is any substance or form of energy released into the environment that is harmful to people or other living creatures.

Analyze This: Nutrients from sewage may harm coastal ecosystems
A new model suggests that 58 percent of coral reefs and 88 percent of seagrass beds are exposed to excess nitrogen from wastewater.
