The publishing of several articles that reveal the vulnerability of farmed fish to the anisakis parasite has prompted the research group in Marine Zoology of the University of Valencia to experimentally assess the infective susceptibility of fish when exposed to this parasite. The results from the ANITEST project, which just ended, show that, in the improbable case that the parasite reaches farms, fish are not very susceptible to being infected. Read More
A group of astrophysicists including two professors from the University of Valencia, José María Martí and Manel Perucho, published earlier this week in the prestigious Astrophysical Journal Letters an image of the jet of the galaxy M87, which shows that the plasma of the jet is configured in two large bright helixes in radio frequencies of almost 3,300 light-years from the supermassive black hole at the centre of the galaxy.
A research group from the Institute of Agrochemistry and Food Technology (IATA-CSIC), in the Science Park of the University of Valencia, has published in PLOS Genetics a study that discovers the genetic mechanisms by which Saccharomyces uvarum, one of the yeasts used to make wine, acts in its fermentation. The study shows for the first time a phenomenon known as “evolutionary convergence” in two different species of yeasts that allows them to adapt to a process directed by humans.
In the third edition of the Parapez study, researchers analysed over 11,000 underwater images to detect the wild species that inhabit the surroundings of the fish farms studied. Read More
A research team from the University of Valencia and the Jaume I University of Castellón shows an increase in the expression of 197 genes in mother mice, and a decrease of 99, when compared with virgin females in contact with offspring. These results demonstrate changes related to maternity that could be related to the maternal defense behaviour of the offspring against males. This work opens the doors to new research focused on the role of these gene expression changes in the brain during motherhood.
Salvador Herrero, a researcher at the Department of Genetics of the University of Valencia (UV), and Laila Gasmi, a doctorate at the institution, in collaboration with research groups from Japan, Canada and South Korea, have discovered a new family of genes present in most insect-infecting DNA viruses, which have integrated multiple times into the genomes of their host and have given them protection against certain groups of parasitoid wasps. The work was published recently in journal Science.
Scientists from the Desertification Research Institute (CIDE, CSIC-UV-GVA) and the Segura Centre for Soil Science and Applied Biology (CEBAS, CSIC) verify that using a single dropper-holder line would optimise the use of water in persimmon and lemon trees. The study contributes to establish guidelines to improve the agronomic design of irrigation, facilitate cultivation work and even achieve increases in production.
Research by the Department of Pharmacy and Pharmaceutical Technology and Parasitology of the University of Valencia (UV) has shown in a preclinical experiment with rats that physical pain induces relapsing with alcohol consumption. The study, published in journal PAIN, has also shown changes in an area of the brain related to motivation for drug intake, and in a second experiment they have shown that the kappa-type opioid receptor (a protein) is key to causing these animals to relapse.
An international astronomy team that the University of Valencia is part of, has just published in Nature Astronomy the image of the heart of the Centaurus A galaxy in the finest detail ever. The work specifies the exact point where the supermassive black hole of this galaxy is located and allows us to observe how a gigantic jet of matter escaping from the black hole at speeds very close to that of light is originated. The image challenges current models of the origin of jets in black holes.
Research co-led by the Centre for Research on Desertification (CIDE, CSIC-UV-GVA) describes the mechanisms that make major forest fires possible. Climate emerges as one of the main triggers by fostering the flammability of the fuel, along with drought conditions and the effectiveness of ignitions. Read More
