Of more than 500 species of sharks in the world’s oceans, scientists have only sequenced a handful of genomes – most recently, white sharks.
Why do scientists spend so much time and money mapping the DNA of species like white sharks? Single studies may offer insights, but the real payoff comes in comparing many species to each other.

Some media have reported shark numbers at 'plague proportions' in Australian waters. But a new analysis suggests the opposite: species such as hammerheads and white sharks have plummeted in number.
Many of Australia’s beaches are now being monitored for shark safety by drones.
Drones are now being used to warn beachgoers about sharks – with groundbreaking accuracy.

The return of white sharks to Cape Cod, Massachusetts was a tourism success story – until a shark killed a swimmer. Can the Cape's residents and visitors learn to share the ocean with these apex predators?

Getting up close and personal can make you like sharks more, even if you already like them.
Sharks have a PR problem. But new research shows that shark ecotourism programs boost people's knowledge and attitudes towards shark conservation – even among those who are green-minded to begin with.

When humans have conflicts with wildlife, the first reaction is often to cull them. But there's little evidence to show that it works, and removing predators can even backfire and make things worse.
