Korean researchers aim to trap marine trash at its source

Though efforts to clean up plastic waste from our oceans are well underway, it’s also vital to stem the tide at a major source of pollution: rivers. Researchers in South Korea are looking to doing just that at a “living lab” facility in Gongju.Continue… Continue reading Korean researchers aim to trap marine trash at its source

“Heaving oscillators” use wave power to extend shipping range

Ships can become mobile wave energy converters, say Chinese researchers, using “heaving oscillators” that draw power from heaving, rolling and pitching movements as they move through the sea, while also acting as motion dampers to improve safety.Contin… Continue reading “Heaving oscillators” use wave power to extend shipping range

This sea worm’s butt detaches from its body to swim off in search of love

In one of the strangest paths to reproduction, this tiny Japanese sea worm actually grows a ‘mini-me’ at its rear end, which it then deploys so it can swim off on its own in search of similar autonomous tail of the opposite sex to spawn with. The worm,… Continue reading This sea worm’s butt detaches from its body to swim off in search of love

We see what was on the trilobite menu nearly half a billion years ago

Some 465 million years since this marine scavenger was caught unawares by an approaching deadly mud current that would bury it alive, it had spent its last hours enjoying a large, varied seafood menu that has, until now, not been pictured in such detai… Continue reading We see what was on the trilobite menu nearly half a billion years ago

Colossal new species may be largest animal that ever existed

An artist's impression of Perucetus colossus, a newly discovered ancient whale species that may now be the largest animal that ever existed

The blue whale has long been considered the largest animal to have ever existed, even dwarfing the biggest known dinosaurs. But now a new species threatens to steal the crown, and upends what we thought we knew about whale evolution.

Megalodon was warm-blooded – and that might have been its downfall

Fossilized teeth are most of the remains we have today of the megalodon, which makes it hard to figure out what it looked like or how it lived. But now, scientists have used those teeth to estimate the ancient shark’s body temperature, and found it was… Continue reading Megalodon was warm-blooded – and that might have been its downfall

DARPA launches program in quest for “Red October” silent submarine drive

Taking a plot point from the 1990 Sean Connery thriller The Hunt for Red October, DARPA is working on a super-silent submarine drive that has no moving parts and provides propulsion through the water using magnets and electricity.Continue ReadingCatego… Continue reading DARPA launches program in quest for “Red October” silent submarine drive

Keeping the Noise Down Under the Sea

A pinwheel sits in an aquarium to simulate an offshore wind turbine. Bubbles come up from the "seabed" to encircle it to demonstrate a bubble curtain with an image of a sound waveform overlaid with the video to show the sound confined to the area within the bubble curtain.

Since sound is the primary sense used by most ocean life, disruptions to the natural noise levels in the ocean from human activities can be particularly problematic for marine life. …read more Continue reading Keeping the Noise Down Under the Sea

Soggy professor breaks underwater-living record in sea habitat

A professor from the University of South Florida has broken the world record for living in an underwater habitat. Associate Professor Joseph Dituri resided inside Jules’ Undersea Lodge in Key Largo for more than 75 days since March 1, 2023 and intends … Continue reading Soggy professor breaks underwater-living record in sea habitat
