Life is full of compromises, and so is evolution. We often wonder about the explanation for particular traits that we find in many different organisms; distinct characteristics present in some of those organisms but not in others. We may hypothesize their story, and it can make sense, but finding actual evidence to support it will […]
It took a multi-million-dollar collaborationship between Discovery Channel and NHK to obtain the first images of a giant squid in its native environment. The broadcasters announced this month that they finally succeeded on filming a relatively small specimen of Architeuthis dux at a depth of 630m in the northern Pacific Ocean. But what makes this […]
The advances in molecular biology and the so called post-genomic era, have improved significantly the fight against many human diseases, in some cases almost leading to their eradication. However, there are still regions of our planet were people suffer from infections and other causes of mortality which are easily avoided in the most developed countries […]
Quantum mechanics and biology are very different fields. The first one studies things that are very small, like atoms, molecules or particles. Biology, on the other hand, deals with complex and big systems, the living beings. Of course, that does not mean that there is no connection at all. Big, complex systems are composed always […]
Nowadays, central Australia is mostly a huge desert. It was not always like that: only five million years ago, this area had a completely different look, with humid forests, rivers, streams and lakes, a strong contrast to the current dry landscape. A significant portion of the Australian desert is, actually, full of water. Water that […]
In biology few issues are as basic as the division and classification of living things. Despite the differences shown by taxa that occupy each of the categories, all living things have a common ancestor and characteristics that unite them. Since Linnaeus (in 1735) to the newest division created by Cavalier-Smith (in the late twentieth century) […]
Maybe you find interesting, as I certainly do, to read in the news that a new species has been discovered somewhere in the World. We recently witnessed the surprising and unusual finding of a new, beautiful monkey in Congo: the lesula ( Cercopithecus lomamiensis ), and you may also remember to read, even in the […]
