Exquisiteurons of Clarke, the most promising tech-marker

Future giant telescopes (JWST, GMT, E-ELT and TMT) will analyze the atmospheres of some exoplanets. They will seek life through biomarkers and technological civilizations with technomarkers. Clarke’s exosurgeons are the new tech-marker proposed by solar astrophysicist Héctor Socas-Navarro. The communication satellites in geostationary orbit, the idea of Arthur C. Clarke…

The ‘switch’ of Alzheimer’s can be activated at 40 years

A team of scientists at the University of Southern California (USA) has discovered, in a study with mice, a process that precedes the accumulation of toxic proteins in the brain, a hallmark of Alzheimer’s disease. Experts reveal how damage to cells called pericytes can trigger white matter disease, which is…
