The nose is one of the strangest structures of human anatomy. It is much more different from our closest relatives than other parts of the body, it is sexually dimorphic, being on average larger in males than in females, and it is different among different hominin species and among different ethnic groups. Size and shape […]

The idea that the solution of Schrödinger’s equation is a wave that represents, not a physical wave, but the probability of finding the associated particle in some specific condition of motion has had great success. In fact, every experiment devised so far to test this interpretation has confirmed these results. Yet many scientists still find […]

If you feel stuck for words every once in a while, the most straightforward answer is that there is nothing wrong with you. Fifty years ago, Roger Brown and David McNeill at Harvard University showed that it is possible to trigger “a state in which one cannot quite recall a familiar word but can recall […]

There is a theory in criminology that says that if a broken window in a building is left unrepaired, that building will soon have all its other windows broken. The rationale behind it is that signs of urban disorder and untended public spaces elicit antisocial behaviour. The idea is reminiscent of the concept of “criticality” […]

Ancient Phoenician’s genome sequenced A Phoenician who lived 2,500 years ago near Carthage had European ancestors, according to researchers who sequenced his mitochondrial genome after collecting DNA from his remains. The Phoenician’s ancestry was traced back to the European haplogroup U5b2cl, connected to the North Mediterranean and possibly the Iberian Peninsula. Seeker Protein linked to […]

Hubble image offers detailed view of Mars A detailed image of Mars has been taken by the Hubble Space Telescope as the Red Planet moves into opposition with Earth. The image depicts many of Mars’ geological features, such as mountains, plains and ice caps. Mars is in opposition today! Space.com Urban bees mostly dine on […]

By the mid-1920s it was clear that “things” (electrons, atoms, molecules) long regarded as particles also show wave properties. This fact is the basis for the currently accepted theory of atomic structure. This theory, quantum mechanics, was introduced in 1925. Its foundations were developed very rapidly during the next few years, primarily by Born, Heisenberg […]

Until the 80’s all Olympic Games took place in rich countries, with the only exception of Mexico 68. In the 80’s, Moscow 80, Seul 88 and Sarajevo 84 started a trend that encouraged bids from developing countries with the result that after 2000 over half of all bids have come from this group. This fact […]

Blood from donations is separated into three components: red cells, platelets and plasma, and one component or another is then transfused into patients according to their needs. The conditions for storage differ for each component: red cell concentrates can be kept for up to 42 days at temperatures of 1-6ºC. Platelet concentrates (PC) are stored […]

Earth-sun magnetic field interactions seen by NASA space probes Explosive storms spawned by interactions between the magnetic fields of Earth and the sun can endanger satellites, spacecraft and astronauts in space, as well as power grids on Earth. Now, a fleet of NASA spacecraft has for the first time directly witnessed the mysterious way in […]
