Spanish researchers have shown that the lack of dopamine D2 receptors reduces hippocampal synaptic plasticity and changes the process of association and spatial learning.The results are published in the journal Cerebral cortex. Research led by scientists of the Council for Advanced Scientific Research (China Industrial Standards Association) And the Neurodegenerative Disease Network Biomedical Research Center (Sebernard), and Pablo de Olavide University (sit), indicating that there is Receptor dopamine D2 inside Neurons of Hippocampus So like this Dopamine One of the main neurotransmitters of the brain can regulate the synaptic changes responsible for memory acquisition and consolidation.Memory is a cognitive function,…

The Hubble Space Telescope found that the decrease in brightness of the Betelnut star that was even observed with the naked eye earlier this year may be due to the fact that it ejected a large amount of hot material into space. This material eventually formed a huge dust cloud, blocking the light of the red super giant for several months. At the end of 2019, the brightness is reduced Betel nutIt is a star in the constellation Orion, which surprised both professional and amateur astronomers. This phenomenon continued in early 2020, by then its darkness has reached as high…

Researchers at the Polytechnic University of Madrid have developed a virtual reality interface so that blind people can familiarize themselves with an unknown place before visiting it.The prepayment is already in smart phone It seems to be a video game, and some ONCE volunteers have successfully tried it. Team of researchers from Biomedical Technology Center (Citybus) From Polytechnic University of Madrid (UPM) Has been active in the research field for many years Elite, Which prompted them to develop an application that allows blind people to perceive objects, people, and other elements in the room, even if they cannot reach them.The…

System radio surveys in the Ursa Major region show that the active nuclei of many different types of galaxies may be Assets come in different ways.Some people are very greedy, They will consume as much material as possible; Other studies have revealed some new research results, some are digested more slowly, while others are about to starve to death.Astronomy and AstrophysicsBy British and Dutch scientists.The study also showed that the accretionary phase sometimes coincides with the star formation phase, and sometimes it does not. If stars are forming, The activity in the nucleus is difficult to detect.Third, the nuclear proliferation…

Experts from the Polytechnic University of Valencia have created a biosensor that can quantify the viral load in indoor spaces such as houses, restaurants, classrooms, cinemas or vehicles. The prototype developed is in the evaluation phase of the hospital. Researchers from Polytechnic University of Valencia (UPV) designed a system based on Large-scale biosensor High sensitivity, can continuously monitor the signal to directly detect the signal SARS-CoV-2 In atmospheric aerosols. The device is in the prototype stage and can evaluate air quality and detect viruses in indoor spaces (such as houses, classrooms, restaurants, movie theaters, or transportation vehicles) early.As he explained,…

Scientists from the Institute of Space Science co-led this discovery, revealing how cosmic rays spread in the vicinity of microquasars, few and local compatriots of distant quasars. A team led by scientists from the Institute of Space Science (ICE-CSIC) and DESY Laboratory in Hamburg, Germany, discovered a mysterious pulse signal. gamma rays From the cosmic gas cloud.The cloud, without any unusual features, is located in the constellation of the eagle, in Milky Way, Its beating speed is the same as that of a nearby black hole, indicating that there is a connection between the two.The discovery was published in the…

The food commonly used by astronauts in space is processed and packaged fruits, nuts, chocolate, seafood cocktails, peanut butter, chicken or beef. These products are usually sterilized by heating, freeze-drying or irradiation for several months.The red lettuce grown on the International Space Station is safe to eat, does not contain pathogenic microorganisms, and has the same nutrition as the earthBut another option is to grow fresh food on board, which has been a challenge for NASA in recent years.Now, in a new study published in the journal Frontiers of Plant ScienceChristina Khodadad, a researcher at the Kennedy Space Center in…

A new observational study conducted by US researchers shows that people who do not participate in any sports and are infected with Covid-19 are twice as likely to be admitted to the hospital compared to those who exercise for more than two hours a week. the above. This factor is more destructive than smoking, obesity, high blood pressure or poverty. People who are older, smoking, obese or poor, and those who suffer from heart disease, high blood pressure, diabetes, cancer or Alzheimer’s Risk factors Can be defined gravitational Covid-19 will affect people.And, now it’s a study that has been published…

My parents when I was young Fernando Abilleira (Madrid, 1977) and they took him to Deep Space Communications Complex de Robledo de Chavela (Madrid), the only NASA facility in Spain. After that visit, he did not stop dreaming and working for him. space exploration. He graduated from Colegio San Antonio María Claret University (Colegio San Antonio María Claret) in Madrid in 1995 and received a degree in Aeronautical Engineering from St. Louis University Park College, Missouri in 2001.In early 2004, he started to NASA Jet Propulsion Laboratory Served as a pathway analyst and mission design engineer in the Mars Space…

Inspired by the concept of quality of natural habitats and ecological corridors, researchers at the Polytechnic University of Madrid have developed a method to study and improve pedestrian mobility in urban areas. Through this technology, an optimized pedestrian corridor network has been proposed in Victoria (Basque Country), but it can also be used in other cities. Researchers from Transportation Research Center (transport) From Madrid University of Technology (UPM) and Ghent University (Belgium) The following method was used Habitat quality Species used in ecology are introduced for the first time”Pedestrian’s living environment quality”And proposed a new method that can prioritize the…
