When talking about the extraordinary landscapes of the Canary Islands, many still do not think the sky and that these islands are a unique astronomical viewpoint in the world. With the aim of training professionals to help interpret the cultural and natural heritage of the sky canary, Institut d’Astrophysique de Canarias (IAC) was launched successfully in late March during the first accreditation of Starlight guides.
Before the summer, the islands will have these new guidelines trained with the rigor necessary to introduce visitors to the science of tourism routes from the stars. The 15 students who are already enjoying the course, of the 60 people who sued, starting this week its second part, which ends next weekend with the practices in the National Park Caldera in La Palma. Final exams are May 26, after the third and final installment.
Popular science, environmental education and the stellar observation articulate this course with theoretical and practical courses on various topics, from the telescopes and instruments, and the great astronomical events, the security protocols in the mountains, weather, space protected, astronomical photography, the key legislative tourism law or communication techniques for managing groups, among many other issues.

The fishing industry is Often discard the livers of fish, But a team of Researchers from the University of Almeria has Confirmed That They Are A rich source of polyunsaturated fatty acids, Substance beneficial to health. The liver of anchovy is One That contains the Highest amount.
So far the livers of the fish Hardly used, with exceptions Such as cod, Which Occurs in the well-known medicinal oil. In general, the Fishermen Often Entrails throw Into the sea and If They Reach the factory is one of the first parts of fish Are discarded.
However, These compounds hidden teddies Health Benefits, According To a new study confirms That scientists from the University of Almería published in the Journal of Food Composition and Analysis.
“Edible fish livers Are a rich source of polyunsaturated fatty acids of long chain (LCPUFA, for short), Especially the family of omega 3 s, such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)” SYNC José Luis Guil-Guerrero, principal investigator of the work.

Technical Energy City Foundation (City, based in Ponferrada, Leon-) have just completed the installation of a microterremotos detection network in the area where the plant will be located Technological Development of Geologic Storage of CO2 in the around the town of Burgos Hontomin. This task has been carried out for several months until the installation of 30 high-precision microseismic stations for data collection and registration can detect microterremotos taking place underground.
The earthquake detection network consists of stations that are solar powered and consist of sensors buried two meters capable of measuring three-dimensional movements and send signals to the detectors, which entails taking measures magnitudes of movements that occur in the subsoil, explains the city, as recorded DiCYT.
In the initial phase are taking measurements of natural vibrations of the ground or “seismic noise” that will then be used for investigations of CO2 injection. In addition, this network is able to detect earthquakes worldwide produced a certain extent as occurred in Japan last month and its continuing aftershocks. Also, technicians Ciuden other detectors have been installed to record ground other variables, such as naturally occurring CO2 in the air, layout and composition of the deep rock layers, the gravitational field, electrical and magnetic natural, among others.

An international team of scientists, with Spanish participation, has studied the effect of feeding salt waters of the Agulhas Current (South Africa) to the Atlantic in conditions of global warming. The paper analyzes how the flow can compensate for the decrease of salinity in stabilizing North Atlantic and European climate.
The Gulf Stream (located in the Gulf of Mexico) has always called attention to oceanographers and climatologists. This flow transports huge amounts of warm tropical waters to the North Atlantic and Europe provides a habitable climate.
However, other trends are also important in relation to future systems of currents in the North Atlantic. This was revealed by a survey published today Nature. Experts describe an alternative approach and emphasize the importance of water flow in the Indian Ocean to the South Atlantic (around the southern tip of Africa), the so-called Agulhas current.
This stream, located in the southwest Indian Ocean, carrying waters of high salinity to the southern tip of Africa, where some of them escape to the South Atlantic, which contributes to the strength of the global circulation in the ocean.

A new system based on Artificial Intelligence to determine the vote of a person who has not answered all the questions in a survey of political opinion. Developed at the School of Informatics, Polytechnic University of Madrid, has a reliability above 90% and substantially improve current methods of imputation.
Researchers from the School of Informatics, Technical University of Madrid have developed a fuzzy neural network is able to reconstruct incomplete data sets from a method of numerical and categorical attribution, substantially improving current methods of attributing the opinion polls. The research results were published in the journal Neural Computing & Applications.
The lack of data is a widespread problem in most surveys conducted in many different areas. The lack of precision in political opinion polls is due in large part to the current treatment of unanswered questions. The most common technique to address this shortcoming is the imputation, whereby missing data are calculated and added to the sample to obtain a more complete set. Imputation methods can infer numerical and categorical data.

It has been shown that snuff consumption is associated with angina mortality in diabetic patients. In the general population, advice to quit smoking at least get a 5% leave the snuff in a year, while the intensive intervention with follow-up, get that 20% leave the snuff. Snuff consumption is a risk factor for the development and progression of diabetes. The snuff kills 53,155 people annually.
The study “community randomized clinical trial of an intervention with intensive counseling for the cessation of snuff in diabetic patients Primary Health Care (Study ited), the Institute for Research in Primary Care (IDIAP Jordi Gol), was done in 98 centers Primary Care of the province of Barcelona and enrolled a total of 420 nursing and medical professionals.

A researcher at the Spanish Institute of Oceanography (IEO) explored during the first half of April, channel funds Menorca aboard the German submarine JAGO, looking for newly settled juveniles of the spiny lobster. This technology has successfully been able to confirm the hypothesis that recruitment depth is viable.
David Diaz of the Marine Reserves team and Coastal Ecology (RESMARE) Balearic Oceanographic Centre of the Spanish Institute of Oceanography (IEO) conducted several dives in the submarine, manned JAGO, in order to determine the biological, environmental and physiographic areas in which supposedly concentrate juvenile spiny lobster (Palinurus Elephas).
There were three dives, each of which are prospective for four hours a transect of more than one kilometer in length between 70 and 90 m depth by scuba unviable. The main objective of the dives was the visual censuses from the submarine, obtaining a complete record of the transect with a video camera high definition. In the dives were determined the most characteristic species of crustaceans and fish, and there was a general description of the observed communities. Detailed information on habitat and biological characteristics and environmental funds will Lobster a posteriori from comprehensive analysis of the images in the film.

Researchers at the University of Salamanca have found that the parasite Dirofilaria immitis, A worm of the family of the filariae, not only affects the cardiovascular system and lung of animals like cats and dogs, but also the renal system and, moreover, when in this phase is an indication that the disease known as heartworm, is already in an acute phase, which, treatments have to be different.
“We worked with a parasite called Dirofilaria immitis, A nematode found in the circulatory system of dogs and cats and causes vascular and pulmonary disease in its final stages affects the heart causing a heart attack, “said Rodrigo Garcia Morchon, Parasitology Department investigator who has Research presented at the Institute of Natural Resources and Agricultural Biology of Salamanca (IRNAS) center of CSIC, the first time publicly discussed before displaying it at conferences, although it has been accepted in scientific journals.
“It is an endemic disease in the area and we are seeing now Matacan also affects the glomeruli of the renal system renal system, which exacerbates the condition of the dogs,” he says. “We tried to help detect parasite antigen in the urine of dogs to assist the veterinary staff that can diagnose the disease depending on disease state,” he says, because “when it causes disease is acute renal status and treatment has to be different, “said the researcher, who belongs to the group of Professor Fernando Simon.

On April 26, 1986 occurred northwest of the Ukrainian town of Chernobyl the largest nuclear accident in history. Despite the extent of the disaster, 25 years later, their actual impact remains unknown. An international research team now demonstrates for the first time that birds may be more susceptible to radioactivity by the coloration of their plumage.
The radioactivity causes oxidative stress, damage biological molecules and may have “significant” adverse effects on organisms if present in relatively high doses, as found in some areas around Chernobyl.
“In the case of birds studied, these effects were detected in the abundance of populations,” SINC Ismael Galvan, lead author and researcher at the Laboratory of Ecology, Systematics and Evolution at the University of Paris-Sud (France) .
The study, published in the journal OecologiaThe abundance of birds decreased as increased levels of radioactivity in the outskirts of Chernobyl (Ukraine). In total, researchers analyzed the abundance of 97 species of birds exposed to different levels of radiation over four years.
