París, July 12, 2022.- Webb’s enormous mirror and precise instruments joined forces to capture the most detailed measurements of starlight filtering through the atmosphere of a planet outside our Solar System to date. The spectrum of light – which contains information about the makeup of a planetary atmosphere 1,150 light-yearsContinuar Leyendo
Washington, July 12, 2022.- The international NASA/ESA/CSA James Webb Space Telescope has delivered the deepest, sharpest infrared image of the distant Universe so far. U.S. President Joe Biden unveiled the image of galaxy cluster SMACS 0723, known as Webb’s First Deep Field, during a White House event on Monday 11Continuar Leyendo
It takes a lot of time — and money — to diagnose Alzheimer’s disease. After running lengthy in-person neuropsychological exams, clinicians have to transcribe, review, and analyze every response in detail. But researchers at Boston University have developed a new tool that could automate the process and eventually allow itContinuar Leyendo
Many people are familiar with the hole in the ozone layer over Antarctica, but what is less well known is that occasionally, the protective ozone in the stratosphere over the Arctic is destroyed as well, thinning the ozone layer there. This last happened in the spring months of 2020, andContinuar Leyendo
Using a state-of-the-art method, researchers at DZNE and the University of Texas have succeeded for the first time at unraveling the effects of autoimmune antibodies, that are directed against the brain, in detail at the atomic level. To this end, they studied two antibodies that dock to so-called GABAA receptorsContinuar Leyendo
Microglia, a type of central nervous system cell, is primarily responsible for neuronal death in Leigh Syndrome and the neurological symptoms related to this mitochondrial disease. This is the conclusion of a research group from the Institut de Neurociències of the Universitat Autònoma de Barcelona (INc-UAB) in a new studyContinuar Leyendo
The eye’s light-sensing retina taps different circuits depending on whether it is generating image-forming vision or carrying out a non-vision function such as regulating pupil size or sleep/wake cycles, according to a new mouse study from the National Eye Institute (NEI) and the National Institute of Mental Health (NIMH). TheContinuar Leyendo
Researchers from LMU and Saarland University have entangled two quantum memories over a 33-kilometer-long fiber optic connection — a record and an important step toward the quantum internet. München, July 07, 2022.- A network in which data transmission is perfectly secure against hacking? If physicists have their way, this willContinuar Leyendo
