Environmental DNA provides a wealth of information for conservationists, archaeologists and forensic scientists. But the unintentional pickup of human genetic information raises ethical questions.

El Niño can trigger intense and widespread periods of extreme ocean warming known as marine heat waves. They can devastate marine life.
The discovery of the deepest fish in a Japanese trench raises the question, what else is out there? But before the mind leaps to all things dark and spooky, take a fresh look at life in the deep sea.
The ocean twilight zone could store vast amounts of carbon captured from the atmosphere, but first we need a 4D monitoring system to ensure ramping up carbon storage does no harm.
Considered too deep for most reef biologists, and too shallow for deep-sea researchers, most deep reefs are unprotected.
Rats are disrupting the flow of nutrients towards the sea on many tropical islands – this has consequences for fish behaviour and the wider ecosystem.
A new study shows that a time stamp can be put on mercury that accumulates in fish eyes, offering a window into their lifetime exposure.
A recent study offers evidence that marine biology’s biggest stage is broken, and suggests ways to fix it.
Black corals provide critical habitat for many creatures that live in the dark, often barren, deep sea, and researchers are learning more about these rare corals with every dive.
A mass die-off of crustaceans occurred on England’s north-east coast last autumn – the government’s explanation of the cause is unlikely to be true.
Scientists don’t know what prompts turtle hatchlings to emerge from their nests and head for the water, but vibrations appear to play a role.
Our ocean forests of seaweed are enormous. But these quick-growing, life-supporting forests are already vanishing.
Sharks are much more severely threatened by humans than vice versa. A marine biologist explains how people can help protect sharks and why some strategies are more effective than others.
Using urine and signature whistles from other dolphins, a team of scientists has shown that dolphins use signature whistles like names and hold mental representations of other dolphins in their minds.
The Soviet Union was a latecomer to industrial whaling, but it slaughtered whales by the thousands once it started and radically under-reported its take to international monitors.
Rising concern about possible environmental damage from the active ingredients in sunscreens could have ripple effects on public health if it causes people to use less of them.
A terrifying sight in ancient waters, the megalodon shark was once the most feared creature in the sea.
Frilled sharks haven’t changed for about 80 million years! And while they may look a bit like snakes from a distance, they are actually much more similar to other sharks close up.
The ocean is often considered a silent universe. But many recent studies highlight the importance of the soundscape for many marine species, both large and small.
With nine brains, blue blood and a talent for camouflage, the octopus is one of the most fascinating creatures in the sea.
