Titin is a «titanically large» protein — the largest in the human body — which enables elastic movements of our muscles, including the heart. Mutations in the titin gene (TTN) that impair this function are the most frequent cause of a heart muscle disease known as dilated cardiomyopathy (DCM), whichContinuar Leyendo
From panoramas to close-ups, from 3D maps to a wheel selfie, the Earth-bound twin of ESA’s Rosalind Franklin rover is testing the wide range of photo settings that will deliver the greatest science possible during the ExoMars mission on the Red Planet. París, Nov 08, 2021.- The scientific eyes ofContinuar Leyendo
The galaxy Messier 87 (M87) is located 55 million light years away from Earth in the Virgo constellation. It is a giant galaxy with 12,000 globular clusters, making the Milky Way’s 200 globular clusters appear modest in comparison. A black hole of six and a half billion sun masses isContinuar Leyendo
Blocking a molecule that draws sensory nerves into musculoskeletal injuries prevents heterotopic ossification (HO), a process in which bone abnormally grows in soft tissue during healing, UT Southwestern researchers reported in a study. The findings, published in Nature Communications, suggest that drugs currently being tested in clinical trials to inhibitContinuar Leyendo
In what is believed to be one of the largest studies of its kind, Johns Hopkins Medicine researchers have shown that antibody levels against SARS-CoV-2 (the COVID-19 virus) stay more durable — that is, remain higher over an extended period of time — in people who were infected by theContinuar Leyendo
Among the neurotransmitters in the brain, dopamine has gained an almost mythical status. Decades of research have established its contribution to several seemingly unrelated brain functions including learning, motivation, and movement, raising the question of how a single neurotransmitter can play so many different roles. New York, November 02, 2021.-Continuar Leyendo
Developing a machine that processes information as efficiently as the human brain has been a long-standing research goal towards true artificial intelligence. An interdisciplinary research team at Heidelberg University and the University of Bern (Switzerland) led by Dr Mihai Petrovici is tackling this problem with the help of biologically-inspired artificialContinuar Leyendo
For the first time, researchers have used human data to quantify the speed of different processes that lead to Alzheimer’s disease and found that it develops in a very different way than previously thought. Their results could have important implications for the development of potential treatments. Cambridge, October 31, 2021.-Continuar Leyendo
An international team of researchers, led by University of Winnipeg palaeoanthropologist Dr. Mirjana Roksandic, has announced the naming of a new species of human ancestor, Homo bodoensis. This species lived in Africa during the Middle Pleistocene, around half a million years ago, and was the direct ancestor of modern humans.Continuar Leyendo
Most elements lighter than iron are forged in the cores of stars. A star’s white-hot center fuels the fusion of protons, squeezing them together to build progressively heavier elements. But beyond iron, scientists have puzzled over what could give rise to gold, platinum, and the rest of the universe’s heavyContinuar Leyendo
