The research may point to more effective therapeutic targets for deadly diseases by prions Scientists at the Scripps Research Institute have determined for the first time that prions, infectious protein fragments devoid of DNA or RNA that can cause fatal neurodegenerative diseases, are capable of Darwinian evolution. The study of Scripps Florida in Jupiter, USA, shows that prions may develop a large number of mutations at the level of protein and, through natural selection, these mutations can produce evolutionary adaptations such as resistance to drugs, a phenomenon that was known before only in bacteria and viruses. These findings also indicate that the normal prion protein, which occurs naturally in human cells, can become a focus of treatment more effective than their abnormal toxic relationship.

This information is critical to maintain genetic diversity, and will properly develop conservation plans for the water rat (Arvicola sapidus). Researchers at the Biological Station of Doñana (CSIC) and the UGR have jointly addressed the population genetic and phylogeographic study of the species throughout its range (France and the Iberian Peninsula)
This work has been produced by Alejandro Centeno Cuadros,

Scientists from the Biological Station of Doñana (CSIC) and the University of Granada have characterized the genetic diversity of populations of animal species (in this case, a mouse) throughout its range, a fundamental input to properly develop conservation plans for this species.
A team of researchers from the Veterinary Faculty of the Complutense University of Madrid (UCM) has developed a simple and rapid method to distinguish the flesh of quail, pheasant, dove and other game birds through DNA analysis. Verification of the authenticity of such meat prevents fraudulent marketing under names that do not correspond with the real identity of the product
“Now we can differentiate the meat of these species of other birds in everyday use, such as chicken (Gallus gallus), Turkey (Meleagris gallopavo), The Muscovy duck (Carina moschata) Or goose (Anser anser), “Stated Maria Rojas, an author of the study.

According to the German “Bild” reported that on the 24th, Mexico, recently announced an incredible television news: May 2007, a farm in the country, the people in an animal trap discovered still alive, “alien baby” . Now, scientists have of this investigation.
Three times before trying to drown it? Mexican TV star host, but also a UFO expert Shigemori, in its program, pointing has been turned into a specimen of “alien baby” photos, excitedly said: “I am sure these photos are real!” alleged that the farm staff at that time due to fear, this “alien baby” drowned alive. It is constantly struggling with death, wriggling the body, but also cry. Farm workers have tried three times, allowed to stay in the water for several hours to finally kill it. It was like people, like lizards?
