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.

The chances of your genetic data being recorded by the state depend on who you are.
Nanotechnology isn't science fiction – you can find it in the latest TV screens, solar cells and tennis rackets.
Reading over the consent form.
You should be aware of the amount of genetic information you might disclose in a research study – and what the benefits and risks will be.
Some animals seem to have missing genes – but the reality is a lot more intriguing.
Massive online DNA databases can be used as a resource to discover viruses -- even if the data had not been explicitly collected for that purpose.
What can a single person’s flu infection tell you about how the virus changes around the world?
Xue and Bloom
New genetic technologies are letting us look at flu evolution right where it starts: within individual people, while they're sick.
An artist’s impression of an ancient, 100% African sea cow.
Sea cows (Sirenia) descended from four legged mammals that roamed Africa when this continent was isolated. They belong to the Afrotheria, the 'African beasts'.
Genetic techniques can help make pollen useful for cracking criminal cases.
Karen L. Bell
Pollen is all around us, is extremely durable and can provide clues about where someone's been. A new genetic technique will make it easier to use pollen evidence in criminal investigations.
Surface oil slick from the Deepwater Horizon oil spill.
Andreas Teske, University of North Carolina Chapel Hill.
Genetic analysis shows that marine bacteria broke down much of the oil from the 2010 Deepwater Horizon spill. These findings could lead to more effective cleanups after future spills.
Scientists today are inundated with data.
Big Data produces mountains of information, but it's useless for science unless we're asking the right questions.
It’s a lot for a person to puzzle out… call in the computers!
Modern biological research relies on big data analytics. Vast reservoirs of memory and powerful computing ability mean machines find patterns and make meta-analyses and even predictions for scientists.
Genetic techniques are helping scientists work out how to stop invasive species before they rack up huge environmental and financial costs.
Hydrothermal vents on the seafloor hold the key to understanding the evolution of cellular life.

DNA profiling is a powerful tool, but being faced with identical DNA from identical genes has been a problem - until now.
Finding the mutations.
Genomics is increasingly hailed by many as the turning point in modern medicine. Advances in technology now mean we’re able to make out the full DNA sequence of an organism and decipher its entire hereditary…
Mum’s gone to Iceland.
The traditional picture of Vikings is one of boatloads of hairy men pillaging their way along the coasts of Europe. Though true to some degree, this stereotype has more recently been tempered with the…
Behold the femur.

When a human bone was found on a gravelly riverbank by a bone-carver who was searching for mammoth ivory, little did he know it would provide the oldest modern-human genome yet sequenced. The anatomically…
Knowing your DNA will is not a panacea.
Walter Gilbert won the Nobel Prize in 1980 in Chemistry for his contribution to sequence DNA, or “determination of base sequences in a nucleic acid”. Mohit Kumar Jolly, researcher at Rice University and…
