In science, for a phenomenon to be reliable, it needs to be validated by a certain statistical value, the p-value, which by giving an estimate of the probability that the result would be the product of chance, serves as a measure of the probability that a certain event happening is true. So far, the convention […]
Like father like son. We have all heard it one time or another. The layman explanation to hereditary characters. Whether the cause is genetic inheritance or the effect of growing up in a certain environment, is quite something else. When talking about the origin of intelligence, there are always discussions. Even though there is undoubtedly […]
Unless you’ve been sitting in a cave for the last couple of years, you have probably heard about the new great promise of gene therapy: the gene editing CRISPR system. This new addition to the molecular biology toolbox is groundbreaking for what it implies. It does not simply “force in” a healthy copy of whichever […]
Diabetes is a disease typically associated with old age, especially when speaking of type 2, characterized for insulin resistance, and associated with obesity and therefore, more likely to occur in old age. A recent couple of papers published in Cell and Science Translational Medicine point to the healing potential of a fasting-mimicking diet for resetting […]
What determines being left or right handed? As a scientific question might seem irrelevant, but actually handedness is a good example of a brain phenomenon called lateralization which basically refers to the location of certain brain activities in one brain hemisphere or the other (for example, language areas are located in the left hemisphere). There […]
We live in a society permanently obsesed with the idea of youth. Therefore, it is not surprising to find supposedly miraculous potions, ointments and elixirs that offer precisely that. But the idea of permanent youth is not a new idea, it comes from way back, as does the notion that young blood would help rejuvenate […]
Since we were kids (unless under the spell of a creationist education), we have been told that genetics is the reason for the colour of our eyes, our hair, our height and whether we look more like mum or dad. In the last few years, it might seem to many that gene association studies have […]
For a while, new evidence has been accumulating linking the gut microbiota to brain function. A new paper published recently in Cell Reports, shows that the intermediary is a type of white blood cell, evidencing as well the relationship between the brain and the immune system. While the crosstalk between the peripheral immune system and […]
One of the worst things that can happen to someone that loves talking as much as I do is losing my voice. What to most people is just a temporary inconvenience -or a relief depending on who you ask- for some is a real hindrance. Patients that suffer from a permanent impairment to their ability […]
A lot has been said and written about what makes women physically attractive, from having full lips and/or breasts to being shorter than a man, to having a symmetrical face to having a low waist-hip ratio (WHR), all being indicators, at least in theory, of potential reproductive fitness . For instance, a low WHR has […]
