¿A dónde va la grasa desaparecida cuando adelgazamos? A pesar de la preocupación mundial por el sobrepeso, y de los esfuerzos que mucha gente invierte en seguir dietas o hacer ejercicios que la ayuden a perder los kilos sobrantes, muchas personas, e incluso bastantes profesionales de la salud, no tienen muy claro adónde va a parar la grasa corporal...
Descubren que las nuevas neuronas están “ávidas” por transmitir información Al contrario de lo que postulaba un dogma clásico de la biología, desde hace un par de décadas se sabe que el cerebro sigue fabricando neuronas durante toda su vida, un proceso conocido como “neurogénesis”. Sin embargo, los científicos todavía ignoran cuál es la función de esas nuevas neuronas y...
