A research team at the University of Navarre has detected the presence of the prion protein in the digestive tract of three animal species: the autochthonous Pyrennean cow, in a primate and in rats. This study is the first to describe the exact location of the “healthy” form of the prion (PrPc), a protein necessary for the development of prionic diseases in these three species.
The results obtained by the Navarre researchers provide new data on the propagation of the prion and on the development of encephalopathies through the ingestion of contaminated food. It is important to underline that these discoveries could be extrapolated to other species, including the human.
As is known, the majority of cases of bovine spongiform encephalopathy (BSE) detected in Navarre province in the 2001-2004 period correspond to the Pyrennean cow breed. The pathogen prion, PrPsc, is the cause of the mad cow disease. The research into prions is still scant, although it intensified as a result of the mad cow problem.

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
Breakthrough provides a new concept of the design of molecular motors, sensors and electricity generators at nanoscale

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters
Quantum computer parts are sensitive and need to be cooled to very low temperatures. Their tiny size makes them particularly susceptible to a temperature...
