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
A new study has found that the Novaplex SARS-CoV-2 Variant I, II, and IV real-time PCR assays (from Seegene Technology) can reliably detect SARS-CoV-2 in patient samples and identify known variants of interest and concern. Results from the PCR assays were comparable to those from the «gold standard» spike geneContinuar Leyendo
A significant amount of genetic risk for asthma is likely mediated through altered gene expression within the airway epithelium. That is the conclusion of a National Jewish Health-led study to identify genetic variants that cause asthma by altering the function of airway cells. The team’s paper published March 28, 2022,Continuar Leyendo
University of Notre Dame researchers have discovered another way tumor cells transfer genetic material to other cells in their microenvironment, causing cancer to spread. Notre Dame, In, March 28, 2022.- In their latest study, published in Cell Reports, Crislyn D’Souza-Schorey, the Morris Pollard Professor in the Department of Biological Sciences,Continuar Leyendo
Vagus nerve stimulation (VNS), sometimes referred to as a «pacemaker for the brain,» involves a stimulator device that is implanted under the skin in the chest, with a wire that is wound around the vagus nerve in the neck. It helps prevent seizures by sending regular, mild electrical pulses toContinuar Leyendo
