Superconductors are materials with no electrical resistance whatsoever, commonly requiring extremely low temperatures. They are used in a wide range of domains, from medical applications to a central role in quantum computers. Superconductivity is caused by specially linked pairs of electrons known as Cooper pairs. So far, the occurrence ofContinuar Leyendo
Two separate findings by a University of Houston nationally recognized expert in systemic lupus erythematosus (SLE or lupus), a chronic autoimmune disease that affects multiple organs including the kidneys, skin, joints and heart, are being reported in scientific and medical journals. Houston, June 03, 2022.- Chandra Mohan, M.D., Ph.D., HughContinuar Leyendo
Genetically engineered immune cells successfully target the specific cancer cells that may be responsible for relapse of acute myeloid leukemia (AML), a type of blood cancer, and proved effective in animal models of the disease, according to a preclinical study by investigators at Weill Cornell Medicine. The new cell therapy,Continuar Leyendo
Astronomers may now understand why the similar planets Uranus and Neptune are different colors. Using observations from the Gemini North telescope, the NASA Infrared Telescope Facility, and the Hubble Space Telescope, researchers have developed a single atmospheric model that matches observations of both planets. The model reveals that excess hazeContinuar Leyendo
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
