The Loom
Your hands are, roughly speaking, 360 million years old. Before then, they were fins, which your fishy ancestors used to swim through oceans and rivers. Once those fins sprouted digits, they could propel your salamander-like ancestors across dry land. Fast forward 300 million years, and your hands had become fine-tuned for manipulations: your lemur-like ancestors used them to grab leaves and open up fruits. Within the past few million years, your hominin ancestors had fairly human hands, which they used to fashion tools for digging up tubers, butchering carcasses, and laying the groundwork for our global dominance today.

El Psicoanálisis clásico: Freud
El Psicoanálisis clásico : Freud Sigmund Freud nació en mayo de 1856 en Freiberg pequeña ciudad de lo que es hoy actualmente Checoslovaquia, pero que pertenecía a la sazón del Imperio austro-húngaro. Murió en 1939, en Londres, ciudad a la que se traslado debido a los avances del nazismo , ya que era de ascendencia judía. Sus años de experiencia psicoanalítica los realizó en Viena, donde, sin embargo, sus teorías no habrían de tener muy buena acogida durante los primeros años de su trabajo, especialmente entre los círculos médicos ; a pesar de ser el mismo graduado en medicina y especialista en neurología. El legado de sus investigaciones no se centra en la medicina como tal, sino que deben su reconocimiento histórico a la elaboración de un método que parte del inconsciente para tratar las enfermedades mentales : el psicoanálisis.
Bad Astronomy
Well now, this is an interesting discovery: astronomers have found what looks like a "super-Earth" – a planet more massive than Earth but still smaller than a gas giant – orbiting a nearby star at the right distance to have liquid water on it! Given that, it might – might – be Earthlike. This is pretty cool news.

paleoanthropology, genetics and evolution
I have a review of Marlene Zuk's new book, Paleofantasy , in this week's Nature : "Evolutionary biology: Twisting the tale of human evolution" [1] . I can't replicate my review here, but for people who have access to Nature I thought I'd bring attention to it. And if you don't have access, I wanted to share a couple of my reactions. It was a fun book for me to read. Zuk brings a light-hearted skepticism to a broad array of topics in human evolution.
