This month I present the winner article of the Royal Economic Society Prize 2013 to the best non-solicited paper published in the Economic Journal. The authors are Pau Olivella and Marcos Vera-Hernández. One of the first predictions in the study of Economics of Information is the presence of the “adverse selection” phenomenon. The seminal paper […]

Plant that consumes nickel found in the Philippines A plant that thrives in nickel-rich dirt has been discovered in the Philippines. Rinorea niccolifera can absorb large amounts of nickel through its leaves. UPI Regrown bone in monkeys using pluripotent stem cells It could be possible to grow new bone in humans using induced pluripotent stem […]

Turtles more closely related to crocodiles and birds than snakes and lizards The murky evolutionary history of the turtle has been made a little clearer by researchers using new microRNA data which link the shelled reptiles more closely with birds and crocodiles than to lizards and snakes. Yale University Universe’s evolution recreated in computer simulation […]

Wet sand may have helped ancient Egyptians move massive stones Ancient Egyptians dampened the sand to move the 2.5-ton stones used to build the pyramids to prevent berming and halve the amount of force needed to drag the sled, researchers say. The wet sand reduced the friction, making the sledge easier to move. Scientists at […]

Coral can change physiology to survive warming seas When oceans become warmer or acidic, coral reef apparently have the ability to change their physiology to survive, researchers have discovered. Studying coral off Ofu Island in American Samoa, researchers found that the coral can use their genes to turn on heat-resistant proteins. Nature News Y chromosome […]

Psychologists and neurologists have been interested in the problem of free will since the beginning of their specialities, though the first clearly devised and relevant experiments on the topic were those of Libet and colleagues, in the early eighties. In this famous experiment, subjects who were before a clock, and whose brain electrical waves were […]

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 […]
