Inhibiting an important signaling pathway in brain-resident immune cells may calm brain inflammation and thereby slow the disease process in Alzheimer’s and some other neurodegenerative diseases, suggests a study by Weill Cornell Medicine investigators. The findings point to the possibility of new therapeutic strategies against neurodegenerative diseases, which are relativelyContinuar Leyendo
An international team of astronomers using archival data from the NASA/ESA Hubble Space Telescope and other space- and ground-based observatories have discovered a unique object in the distant, early Universe that is a crucial link between star-forming galaxies and the emergence of the earliest supermassive black holes. This object isContinuar Leyendo
A new study by scientists at The Picower Institute for Learning and Memory at MIT provides the most comprehensive and rigorous evidence yet that the mammalian brain stores a single memory across a widely distributed, functionally connected complex spanning many brain regions, rather than in just one or even aContinuar Leyendo
Acute myocarditis, inflammation of the heart muscle typically triggered by a virus, occurred in about two out of every 1,000 people hospitalized with COVID-19, and was associated with more severe illness and complications in people with COVID-19, especially among people who also had pneumonia, according to new research published todayContinuar Leyendo
An international team of astronomers have used ground-based telescopes, including the European Southern Observatory’s Very Large Telescope (ESO’s VLT), to track Neptune’s atmospheric temperatures over a 17-year period. They found a surprising drop in Neptune’s global temperatures followed by a dramatic warming at its south pole. Munchenm, April 11, 2022.-Continuar Leyendo
Mutant mice are providing scientists with a new neurobiological framework to understand the brain changes observed in distractible humans who carry a common gene variant whose frequency has been associated with Attention Deficit Hyperactivity Disorder (ADHD). The scientists demonstrate that mice that express the variant adopt an inattentive phenotype similarContinuar Leyendo
About 750 million people in the world do not have access to electricity at night. Solar cells provide power during the day, but saving energy for later use requires substantial battery storage. College Park, MD, April 06, 2022.- In Applied Physics Letters, by AIP Publishing, researchers from Stanford University constructedContinuar Leyendo
For two decades, Roger Wiens has built instruments to give humans eyes and a nose on Mars — and now he’s helping add ears as well. West Lafayette, Ind. April 06, 2022.- Wiens, a professor of Earth, Atmospheric, and Planetary Sciences in the College of Science at Purdue University, andContinuar Leyendo
Postdam, April 05, 2022.- In order to understand and predict volcanic events even better, a better understanding of the diverse underground processes involved is required. A new way to detect such processes, even if they are very subtle, is to use fibre optic cables as sensors. The analysis of lightContinuar Leyendo
Giant viruses represent a unique group of viruses that are similar in size to small bacteria. Medusavirus — a special type of giant virus — was first isolated from a hot spring in Japan. Interestingly, genetic studies showed that medusavirus was more closely related to mature organisms called eukaryotes thanContinuar Leyendo
