Irakurri euskaraz Methane released from Arctic permafrost could cost trillions worldwide Scientists warn that large amounts of methane that could be released from the melting Arctic permafrost could have a huge global economic impact. The release of 50-gigatonnes of methane over 10 years could cost $60 trillion worldwide, according to a study published in the […]

There is a strong tendency to consider that every scientific or technical solution to a particular problem is irrefutable. Nowadays, scientific and technological knowledge usually eludes public criticism and even we have seen how important government decision making were made by the so-called technocrats .

Choose your favorite convex polyhedron in the space. Make sure it is convex, since the current post is restricted to that kind of polyhedra An unfolding of your convex polyhedron is a development of its surface to a single polygon in the plane (possibly overla pping). In order to obtain an unfolding, the surface of […]

Irakurri euskaraz New study of foragers undermines claim that war has deep evolutionary roots One of the most insidious modern memes holds that war is innate, an adaptation bred into our ancestors by natural selection. This hypothesis—let’s call it the “Deep Roots Theory of War”–has been promoted by some intellectual heavyweights. A study published today […]

One of the most surprising and fascinating facts about scientific research is that one never truly knows which directions investigations may take. Along the way that goes from gathering data, to the path that links our initial question and the answer we pursue, we find numerous, intriguing and unexpected little ramifications and hideous sideways that […]

Our brain constitutes one of the finest pieces of natural machinery known, and it allows us to efficiently interact with our environment: searching for food, avoiding predators, communicating with other individuals, and even some more sophisticated stuff — like enjoying a well composed piece of classical (or rock) music.

Irakurri euskaraz Clouds protect habitable planets from star’s heat According to a recent study that developed a 3D model to explore how clouds affect temperatures on exoplanets, the number of habitable worlds could be double the amount previously thought. The study found that as many as 60 billion exoplanets fall within a habitable zone around […]
