Slow shaking under Tokyo could mean a giant earthquake Slow-motion earthquakes beneath Tokyo are becoming more common, raising concerns of another megaquake like the one in 2011. GPS sensors are being used to track the slow shifts, which are unreadable by seismographs, and scientists have found that the shifts are coming more frequently but seismologists […]

Economic models of perfect competition and of monopoly only need to include individual behavior that takes the environment as given. In the case of perfect competition, individual firms and consumers only need to know the prevailing market prices to decide their purchasing and production plans, whereas the monopolist needs to know the demand it faces […]

Fruit flies can make sudden turns similar to fighter jets Fruit flies are capable of sharp turns, like those of fighter pilots, according to researchers studying the ways the insects evade predators. When sensing a threat, the Drosophila hydei flies can execute banked turns at speeds five times faster than when turning normally. Los Angeles […]

Every year, as the International Women’s Day approaches, a classic topic for the media is to summarize statistics related to the gender wage gap . The empirical evidence is overwhelming: differences between men and women in the labor market are persistent in all countries. If we look at Europe and US data in recent years […]

Irradiated scrap metal helps researchers recreate a supernova Scientists have simulated a supernova with the help of some radioactive waste and a particle accelerator at CERN. Researchers took leftover irradiated scraps of metal containing titanium-44, which is made naturally by supernovae, to produce a beam and sent it into a chamber filled with helium to […]

One of the most classical problems in philosophy is the existence and nature of free will. Though the growth of our scientific knowledge about the brain, and about the universe in general, is making the notion of ‘free will’ less and less tenable, it seems that the major difficulty becomes to reconcile this idea with […]

Salamanders may be getting shorter due to climate change Appalachian salamanders have gotten shorter in the past 50 years, possibly adapting to warmer, drier weather conditions. Researchers compared specimens they collected with those collected by museums from the same areas since 1957. They found that each generation of salamanders in several species grew 1% smaller […]

Iron dust helped plankton thrive during last ice age Plankton gorged on iron dust during the last ice age, causing them to thrive and absorb vast amounts of carbon dioxide in the air, according to a study published in the journal Science. Some scientists argue that by seeding areas such as the Southern Ocean in […]

The literature of experimental economics has documented that individuals consistently make voluntary payments. Two methodological questions arise from this fact. First, which are the precise drivers of this pro-social behavior and, second, whether these findings can be extended to real life situations. Tobias Regner (2014) addresses these questions comparing theoretical and laboratory results with the […]

The most distinctive feature of modern economics is probably its reliance on the methodology of mathematical model building. The final aim of scientific model building is illuminating real phenomena; furthermore, models are basically logical arguments, whose main virtue is that they allow us to see very clearly what follows, and also what does not follow […]
