About 36 million people have blindness including 1 million children. Additionally, 216 million people experience moderate to severe visual impairment. However, STEM (science, technology, engineering and math) education maintains a reliance on three-dimensional imagery for education. Most of this imagery is inaccessible to students with blindness. A breakthrough study byContinuar Leyendo
La astronauta de la ESA Samantha Cristoforetti previsiblemente asumirá el mando de la Estación Espacial Internacional durante la expedición 68a, en virtud de un acuerdo de principio adoptado por los socios internacionales el día 19 de mayo, pendiente de la consolidación de los planes operativos y las fechas de lanzamientoContinuar Leyendo

At first glance, the delicate tracery of bright spiral arms and dark dust lanes resembles countless other spiralContinuar Leyendo
Seeing, hearing, thinking, daydreaming — doing anything at all, in fact — activates neurons in the brain. But for people predisposed to developing brain tumors, the ordinary buzzing of their brains could be a problem. A study by researchers at Washington University School of Medicine in St. Louis and StanfordContinuar Leyendo

The disease is characterized by memory loss, caused by the degeneration and death of neuronal cells in several regions of the brain, including the hippocampus, whichContinuar Leyendo
Recently, the eROSITA (extended Roentgen Survey with an Imaging Telescope Array) x-ray telescope, an instrument developed by a team of scientists at Max-Planck-Institut für Extraterrestrische Physik (MPE), has gained attention among astronomers. The instrument performs an all-sky survey in the x-ray energy band of 0.2-8 kilo electron volts aboard theContinuar Leyendo
Nearly half a billion people on the planet have diabetes, but most of them aren’t getting the kind of care that could make their lives healthier, longer and more productive, according to a new global study of data from people with the condition.

Most able-bodied people take their ability to perform simple daily tasks for granted — when they reach for a warm mug of coffee, they can feel its weight and temperature and adjust their grip accordingly so that no liquid is spilled. People with full sensory and motor control of theirContinuar Leyendo
Within the next decade, the novel coronavirus responsible for COVID-19 could become little more than a nuisance, causing no more than common cold-like coughs and sniffles. That possible future is predicted by mathematical models that incorporate lessons learned from the current pandemic on how our body’s immunity changes over time.Continuar Leyendo
The human body is constantly exposed to various environmental actors, from viruses to bacteria to fungi, but most of these microbial organisms provoke little or no response from our skin, which is charged with monitoring and protecting from external dangers. San Diego, May 23, 2021.- Until now, researchers weren’t quiteContinuar Leyendo
