Drastic oxygen losses in the world's oceans millions of years ago coincided with mass extinctions. Scientists see this as a warning about how climate change could affect oceans today.

Dairy farmers used to put sheep brains and chalk in skim milk to make it look frothier and whiter. Coffee, honey and wine have also been past targets of food fraudsters. Can the law ever keep up?
Our children all know the little clownfish Nemo, star of the Pixar film. But why does he have three stripes, rather than one or two? Developmental and evolutionary biology are revealing the answer.
Our new invention tackles one of the greatest impediments to fish migration in Australia: culverts, those tunnels or drains often found under roads.
Zebrafish are known for their black and gold stripes, but researchers are still figuring out how pigment cells interact to form these patterns.
When a dam comes down this fall, a team of scientists will be there to track the environmental changes.
When it comes to small-scale fisheries, there is no one route to sustainability. Finding success stories can help map those paths.
Harnessing the awe-inspiring living light and power of bioluminescent organisms could change the human world.
Sexual organs similar to what we see in sharks and rays today appeared many millions of years ago in much more primitive ancient fishes than was previously thought.
If we are truly invested in addressing the issue of marine plastic and offsetting the potential harms, we have to understand which fish eat plastic and which ones don't.
Australia's oceans are warming faster than the global average, and fish are moving south as a result.
How can marine preserves best protect sea creatures that move in and out of them? Two ocean scientists describe new thinking about designing marine protected areas.
Australia was thought to have some of the most sustainable fisheries in the world, but a recent count has found that fish numbers have plummeted by a third.
New study in mice shows that omega-3 in mother protects babies' gut health for life.
A 400 million year old fossilised fish skull gives us very early and previously unknown clues about how boney fishes evolved into the vertebrates we see today on Earth - including us humans.
Pregnant women should be reassured that eating fish is good for their baby and is very unlikely to cause autism.
New research suggests omega-3s from seafood to be more effective at reducing breast cancer risk than those from plant-based sources.
The noise from motor boats, sonar and other industrial activity interferes with the underwater chatter of fishes.
With coral reefs in crisis around the world, many organizations are working to restore them by growing and transplanting healthy corals. A new study spotlights techniques that help restored reefs thrive.
