The disorder Maedi-Visna that is detected in sheep affects on mammary gland. As it says in the source language, Icelander, it affects lungs and nervous system. The disorder is produced by the lentivirus Maedi-Visna, which belongs to the family of Aids. This virus infects sheep, and until now, there is no evidence of the transmission to humans. This virus, which is known since many years, causes a very slow evolution of the disorder. Therefore, shepherds often do not detect the infection, because sheep die before the disease develops.
In the consensus conference held last September, experts on immunology, diagnosis, prevision and epidemiology of Maedi-Visna disorder participated. Among them we would like to mention the participation as an expert of Beatriz Amorena from the Public University of Navarre, Basque Country. All of them gave the reasons for the need to set a control programme for this disorder. Evidences produced by this disorder were also presented: financial consequences derived from a lower production of cattle caused by the lentivirus and the need to reinforce the health of cattle.
In the meeting representatives of 18 countries participated. In fact, it has been the first strategic action of consensus in the European Union about animal disease and in which the criteria “medicine based on evidence” has been applied. However, these kinds of actions are common in case of human diseases.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
