Being impulsive makes us speak or act without reflecting, moved by the first thing we feel at that moment. This disinhibited and impulsive behavior already has its own genetic basis. A team of researchers from the University of Lleida and the Lleida Biomedical Research Institute (Spain) has identified the variant of a gene related to this personality trait: the impulsivity gene.

It is well established that women have a more developed sense of smell than men, but until now it was not known why.

The Ebola virus has been on a lethal journey since an outbreak in West Africa in March 2014, infecting more than 10,000 people in different countries and claiming some 5,000 victims so far.

Why are most violent crimes, such as assault or murder, committed by a minority of people who are also repeat offenders?

Researchers at the University of Cambridge (United Kingdom) have studied the genome of the Siberian Eskimos and Inuit of northern Canada.

This computational method, a pioneer in its field, has been baptized as SMUFIN (Somatic Mutations Finder) and has been developed by the computational genomics group of the Barcelona Supercomputing Center - Centro Nacional de Supercomputación (BSC-CNS) in collaboration with other research groups Europeans. The study has been published in the journal Nature Biotechnology.

A team of scientists from the Max Planck Institute for Evolutionary Anthropology in Leipzig (Germany) has succeeded in completing the sequencing of the genome of “Ust-Ishim Man”, an anatomically modern male, who lived in Siberia 45,000 years ago, which makes it the oldest known modern human (the former was the genome of the Mal'ta boy from 24,000 years ago). The work has been published in the journal Nature.
