Scientific experiments using animals frequently involve the marking of animals that artificially changes their phenotype. For instance, penguins with flipper bands have been used to study climate change. However, as Saraux et al. show, this banding reduces penguins’ survival rate. Consequently the study may mix up the effects of banding with other changes in penguin […]

This is the ultimatum game: You are provisionally allocated USD10 with the following instructions. You have to decide a way to divide this money with another person. If she or he agrees, the division is carried out. If not, you both get nothing. What would you do? How would you react if you were the […]

3-body problem gets 13 more possible solutions Scientists have come up with 13 new solutions to the “three-body problem,” a situation in which three objects orbit each other in a pattern. The discoveries, which will help astrophysicists further understand planetary systems, brings the total number of solutions to 16. Science now Milovan Šuvakov, V. Dmitrašinović […]

Imagine the following situation: about 100 people have to choose one of them for an important position; they have different preferences about who must be chosen, some may have a stronger or lighter interest in being elected, but, and this is essential, it is very likely that most of them will have to cast their […]

The remains of large animals are prevalent in Neanderthal cave excavations, but the bones of smaller animals such as rabbits were prevalent […]

Zircon grains came from ancient continent Grains of zircon found on the island of Mauritius may have come from the crust of an ancient continent beneath the Indian Ocean. The grains formed almost 2 billion years ago, but the island is only 65 million years old. New Scientist Trond H. Torsvik, Hans Amundsen, Ebbe H […]

Carlos Fuentes, one of the great contemporary Latin American writers, once said that La Historia verdadera de la conquista de la Nueva España (‘The truthful history of the conquest of New Spain’, first published in 1632) was the true foundation of the Latin American novel. This chronicle narrates the conquest of modern-day Mexico by the […]

“Native” water once existed on the Moon A new analysis of lunar soil samples from NASA’s Apollo missions has found evidence that the moon in its early days may have contained “native” water. The findings, which were published in the journal Nature Geoscience, go against prevailing theories that the moon formed from the debris of […]

Markets are the most studied economic mechanism for two main reasons. First, they have existed in most societies. Second, at least since Adam Smith we have learned some of the interesting properties they possess. In particular, the modern General Equilibrium Theory, in its standard version, asserts that rational agents interacting in a competitive market with […]

Metaethics is the branch of philosophy that tries to elucidate, not what is morally good or bad, or how can we know it (this would be the function of ethics), but what is the nature of ethics, of moral language, of moral judgments, and of moral attitudes. The scientific study of morals could be considered […]
