Scientists from the Institute of Evolutionary Biology (CSIC-UPF) have obtained the DNA sequences of the 228 known butterfly species in the Iberian peninsula and compared it to available data for Europe. It compiles 3500 genetic sequences of all the species, with their geographical distribution, and will be useful for the conservation of butterfly biodiversity. The DNA sequences obtained suggest that up to 28% of species could be totally new to science.

A study by the CSIC, CIRCE, the University of Hohenheim, CREMA and CEGMA, has demonstrated that flame retardant pollutants, the classical ones, PBDEs, and the new substitutes, are able to cross the blood-brain barrier and penetrate the brain of cetaceans.
Discovery of new genes that may explain why insects are the most evolutionarily successful group of organisms
They are the Eglp genes, which encode channels that transport glycerol to the inside of the insect cells. The discovery might help to explain why insects are the most evolutionarily successful group of organisms in the history of life. Glycerol accumulation in organs and cells prevents insects from freezing or drying in extreme climates.
