One of the most surprising and fascinating facts about scientific research is that one never truly knows which directions investigations may take. Along the way that goes from gathering data, to the path that links our initial question and the answer we pursue, we find numerous, intriguing and unexpected little ramifications and hideous sideways that […]
In the previous article of this series starred by ribonucleic acids, we found out about how an RNA molecule is able to regulate complex cascades of molecular events as critical as to decide the fate of a whole cell lineage. But RNA is also capable of other intriguing functions, and one of the most recently […]
Among all the molecules that constitute living organisms, DNA (deoxyribonucleic acid) is probably the most popular and certainly it deserves the “molecule of life” surname. However, its role as the keeper of the critical information needed to construct an organism would be useless without the help of a very close relative, with a strikingly similar […]
From a certain point of view, eukaryotic cells could be described as microscopic power plants equipped with factories and energy-generating platforms, inside of which highways and compartments are constantly built and rebuilt, and a fluent traffic provides a constant recycling of structures while getting rid of garbage. The trafficking also involves material coming in and […]
Diabetes is a metabolic disorder characterized by an inefficiency to respond to the glucose requirements of the body, a process largely regulated by the popular hormone known as insulin. Insulin is produced and secreted in a specific type of cells in the pancreas called β-cells, which are able to detect and respond to high glucose […]
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 […]
The molecular base underlying neuronal processes is being constantly enriched by extended research focused on the investigation of mechanisms involving neurological pathologies. This broad field ranges from widely extended diseases like Alzheimer’s or Parkinson’s, to other less well-known, generally low-incidence neurodegenerative pathologies. However, one of the most challenging aims of modern neuroscience is the understanding […]
