Cassini images add clues to Titan’s weather cycle New photos from NASA’s Cassini spacecraft are giving researchers clues to the weather cycle of Titan, one of Saturn’s moons. By studying previous images, scientists think Titan has a hydrologic cycle, in which hydrocarbons rain onto the surface filling the lakes and then evaporating back into the […]

One of the aspects in which modern economics has departed further away from the neoclassical paradigm is the treatment of information after the seminal works of Akerlof, Spence and Stiglitz, who rightly won the Nobel prize for their contributions. Some theoretical models were introduced to explain economic phenomena that did not fit well in the […]

How science goes wrong Scientific research has changed the world. Now it needs to change itself The Economist Astronomers find a “tilted” solar system Scientists have discovered a “tilted” solar system, according to a report in Science. While looking at Kepler-56, a star about 2,800 light-years away, they were surprised to find that the plane […]

We saw in the second entry of this series that predicates like “…is true” have the following linguistic function: applied to an expression that designates a sentence X, they render a new (pro)sentence (“X is true”) that expresses exactly the same as the first proposition. This has lead some philosophers (not a majority, really) to […]

Images catch molecules moving in glass The movement of molecules in the world’s thinnest glass has been captured in images and may help researchers better understand how the substance bends and breaks. Live Science Remains of water-filled asteroid found around white dwarf A white dwarf about 170 light-years from Earth holds evidence of a water-bearing […]

In 2012 the Nobel Memorial Prize in Economic Science was granted to two mathematicians, Lloyd Shapley and Alvin Roth, “ for the theory of stable allocations and the practice of market design”. The market design in their theory was not exactly a market, at least, not the kind one usually calls that way. They are […]

With the delicate economical situation that many developed countries are experiencing in the last years, a significant number of questions and concerns have been risen about how to properly assign and distribute funding to scientific institutions and research group leaders. In particular, a relevant question for science funding could be how to optimize the scientific […]

Ocean health imperiled thrice over Climate change and increases in oxygen-free “dead zones” and acidification each pose health concerns for the world’s oceans, with immediate action required, says a report from the International Programme on the State of the Ocean. BBC Bulk of Earth’s xenon concealed in planet’s core Earth’s atmosphere appears to have only […]

19 elements to have atomic weights adjusted Aluminum, cadmium, gold and arsenic are among 19 elements that are having their atomic weights adjusted by the International Union of Pure and Applied Chemistry. More precise measurements are now available leading to the new weight calculations, which happens rarely. The atomic weight of nonmetal selenium hasn’t been […]

PET helps ID tau protein in the brain PET shows promise in detecting tau protein accumulation in the brain, according to a study in the journal Neuron. Researchers developed a chemical that binds with the substance and used PET to identify areas of the brain at risk of neuronal death. The approach was evaluated in […]
