The simple consumption of a product is part of an ecological footprint that we left in the planet. Our habits produce an impact and thanks to this indicator of sustainability we can measure it. A group of investigators of the UAB have created a methodology that allows to calculate the environmental impact of a specific activity: the...
A team of biophysicists at the UAB have discovered the molecular process involved in AIDS and present their results. In their laboratory they artificially recreated part of the viral process and their conclusions are interesting. Peptides, which enable the virus to fuse with our cells, have a...
The oral antibiotics are administered systematically before a colon surgery. But, is it really necessary this medication? Investigators of the Hospital Vall d'Hebron and UAB think that it is not.

Chromosomes are composed of a material named chromatin. Generally it is accepted that DNA is packaged in chromosomes during mitosis following a succession of chromatin fiber folds. According to a study carried out by UAB researchers, in addition to...
The Catalonian donkey is one of the most endangered donkey breeds in the world. In this study, the investigators J.P. Gutierrez, J. Marmi, F. Goyache i J. Jordana analysed the pedigree information of the Catalonian donkey herdbook to assess the genetic diversity and population structure of the breed. They found that the Catalonian donkey has...
Alcoholism and the hepatic alcoholic illness are heterogeneous clinical entity. We still don't known why people become alcoholic. We also don't known why only a part of them develop the hepatic alcoholic illness. Since the environmental factors do not explain everything, the research efforts are studying the genetic determinants of people. This...
In according with our temperament we run the risk of being an addict. Investigators of the Institute of Neurosciences suggest that people who search constantly new sensations are potentially addicts. This conclusion is the fruit of a study produced with morphine and snooper rats.
Sometimes and without a clock we are capable to tell what time it is or to wake up an hour in particular. Scientists suspect that this skill is mechanized in some place of our body. Investigators of the Service of Neurology have stimulated and inhibited parts of the brain supposedly implied. The results discard the role of the prefrontal lobe...
