Mesozoic-era ichthyosaur had live births on land The fossil remains of a 248 million-year-old ichthyosaur have revealed that the Mesozoic-era reptile died while giving birth with two offspring still inside it. Scientists were surprised to note that the birth was occurring on land, which goes against a long-held belief that the sea creatures delivered their […]

Highly conductive graphene nanoribbons Graphene nanoribbons can conduct electricity much better than was expected. The new graphene nanoribbons differ from other forms by having no rough edges allowing electrons to move ten times more swiftly than theory says they should. The results could have implications in the development of high-end electronics. Nature News Advanced bionic […]

Traditionally, economics is not only about the optimisation of some magnitudes, be they utility, profits, wealth, or social welfare. Beyond the assumption that economic agents are rational beings who always try to make the best possible choice, there is the indisputable fact that the objects of economic research are social phenomena, that have to do […]

Light on X chromosomes To better see how females turn on and off their X chromosomes, scientists at Johns Hopkins University have developed a way to get X chromosomes from different parents to light up in different colors. Dr. Jeremy Nathans and his team engineered mice to breed female babies with X chromosomes from one […]

It is estimated that at least 860 million people live in slums, a number that has been growing by six million a year from 2000 to 2010 (UN-Habitat 2012) . The study of slums worldwide is a very complex problem. We have no good model to study their economic performance, no systematic data and no […]

Tiniest particles can now be put on the scale Tiny technology that uses a fluid-filled microchannel in a silicon cantilever can measure the mass of particles down to the attogram, or one-millionth of a trillionth of a gram. The technology, developed at the Massachusetts Institute of Technology, sends particles through the microchannel. Their passing changes […]

Israeli nurseries are particularly famous amongst economists (at least, amongst experimental economists). An already classical study shown that, following a ‘natural experiment’ in which some day-care centers opted for issuing a fine to parents for late children’s pickups, while other nurseries didn’t, not only helped to decrease (as expected) the frequency of late pickups, but […]

Ancient strips of bamboo hold multiplication table A multiplication table in base 10 has been revealed in ancient strips of bamboo found in China that date back to around 305 B.C. About 2,500 bamboo strips were donated to Tsinghua University in Beijing five years ago, and researchers discovered ancient Chinese calligraphy written on the strips […]
