Many people may not realize that the humble sea urchin is a titan when it comes to the study of biology. Now, researchers from Japan have discovered that sea urchins could help biological studies go further than ever before. Tsukuba City, May 0, 2022.- In a study published in thisContinuar Leyendo
An international team of astronomers used a database combining observations from the best telescopes in the world, including the Subaru Telescope, to detect the signal from the active supermassive black holes of dying galaxies in the early Universe. The appearance of these active supermassive black holes correlates with changes inContinuar Leyendo
For more than 20 years, scientists have known that people with hypertension, diabetes, high cholesterol, or obesity have a higher likelihood of developing Alzheimer’s disease. New York, May 26, 2022.- The conditions can all affect the brain, damaging blood vessels and leading to strokes. But the connection between vascular diseaseContinuar Leyendo
Modern anesthesia is one of the most important medical achievements. Whereas before, patients had to suffer hellish agonies during every operation, today anesthesia enables completely painless procedures. One feels nothing and can remember nothing afterwards. It is already known from electroencephalography (EEG) studies on patients that during anesthesia the brainContinuar Leyendo
Completing a nearly 30-year marathon, NASA’s Hubble Space Telescope has calibrated more than 40 «milepost markers» of space and time to help scientists precisely measure the expansion rate of the universe — a quest with a plot twist. Greenbelt, MD, May 25, 2022.- Pursuit of the universe’s expansion rate beganContinuar Leyendo
Researchers at the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) created a solar cell with a record 39.5% efficiency under 1-sun global illumination. This is the highest efficiency solar cell of any type, measured using standard 1-sun conditions. Golden, co., May 25, 2022.- «The new cell is moreContinuar Leyendo
Scientists from Scripps Institution of Oceanography at the University of California San Diego, the University of São Paulo and UC Santa Cruz collaborated to discover and validate the enzymes responsible for the production ofone of the most toxic and fast-acting neurotoxins associated with freshwater harmful algal blooms in lakes andContinuar Leyendo
Preventing atherosclerosis, the underlying cause of heart disease, means scientists need to understand how immune cells drive inflammation in the arteries. La Jolla, May 21, 2022.- The challenge is that the T cells involved in atherosclerosis are very rare and extremely hard to find in the bloodstream. «This is aContinuar Leyendo
Mysterious fast radio bursts release as much energy in one second as the Sun pours out in a year and are among the most puzzling phenomena in the universe. Now researchers at Princeton University, the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) and the SLAC National AcceleratorContinuar Leyendo
Spanning from 2003 to 2021, this collection of images from the NASA/ESA Hubble Space Telescope features galaxies that are all hosts to both Cepheid variables and supernovae. These two celestial phenomena are both crucial tools used by astronomers to determine astronomical distance, and have been used to refine our measurementContinuar Leyendo
