The deepwater sculpin is not an attractive fish by any conventional standard. You won't find it hanging on a plaque or landing a feature role in a Disney movie. What you might say about the bottom-dweller is that it's a survivor, having managed to eke out an existence at the bottom of Canada's deepest and coldest lakes since the last ice age. Researchers are now sequencing its entire genome to see how this seemingly unremarkable fish has been able to adapt to such extreme environments.

Camelina, an oilseed plant grown in modern-day Ukraine, may have been a more important and widespread crop than previously thought. New findings could inform breeding programs to improve this crop for biofuels applications.

Robotic ammonites, evaluated in a university pool, allow researchers to explore questions about how shell shapes affected swimming ability. They found trade-offs between stability in the water and maneuverability, suggesting that the evolution of ammonite shells explored different designs for different advantages, rather than converged toward a single best design.

According to a new study, the first louse to take up residence on a mammalian host likely started out as a parasite of birds. That host-jumping event tens of millions of years ago began the long association between mammals and lice, setting the stage for their coevolution and offering more opportunities for the lice to spread to other mammals.

The recent Fagradalsfjall eruption in the southwest of Iceland has enthralled the whole world, including nature lovers and scientists alike. The eruption was especially important as it provided geologists with a unique opportunity to study magmas that were accumulated in a deep crustal magma reservoir but ultimately derived from the Earth's mantle (below 20 km).
