Humans are not the only animals with a taste for alcohol. It has been described in different animals in the wild, especially mammals, that they do like to eat overripe fermented fruit, and with it experience similar effects to the ones almost all of us are familiar with. It turns out that some mammals cannot […]
The Hodgkin-Huxley model for the generation of the nerve action potential is one of the most successful mathematical models of a complex biological process that has ever been formulated. Alan Hodgkin and Andrew Huxley described the model in 1952 to explain the ionic mechanisms underlying the initiation and propagation of action potentials in the squid […]
When we consider the variety of possible wonder applications of plasmonic nanoparticles we usually forget a key aspect: how these laboratory results can be transformed into something really usable in everyday life. For that to occur some not-that-simple problems must be resolved first. For example, plasmonic nanoparticles exhibit excellent light-harvesting properties in the visible spectral […]
Everything is connected. Are you familiar with the butterfly effect? According to this idea small changes could have dramatic consequences. Well, I have been thinking about this lately as one question was forming in my mind: Could it be that the ultimate answer to why I am writing this blog post is intimately related to […]
In a new publication led by Dr. Albert Giralt, the researchers discovered the interaction between a transcription factor identified as “Helios” and a protein called “WDFY1” that could help elucidate the link between immunity and schizophrenia . Schizophrenia is an incurable mental illness characterized by relapsing episodes of psychosis. This disorder affects approximately 1% of […]
One of the most mysterious features of quantum mechanics is that if two particles (or photons) interact at some point in time then the properties of these particles will remain connected at future times. A consequence of this is that determining the quantum state of one of the particles simultaneously determines the quantum state of […]
A reported case study in a Colombian woman , member of a family carriers of a mutation in the presinilin 1 gene which leads to early onset Alzheimer’s, has shown that a certain mutation in the gene APOE3 can protect from the cognitive decline associated with Alzheimer’s disease. This woman was already aged 70 but […]
One of the most important scientific objectives in recent years is to find solutions to the problem of climate change and environmental pollution. Unfortunately, this issue is not only related to the amount of CO 2 that is released into the atmosphere from fossil fuels. The chemical industry, in the complex processes it carries out […]
Graphene is a diamagnetic material, this is, unable of becoming magnetic. However, a triangular piece of graphene is predicted to be magnetic. This apparent contradiction is a consequence of “magic” shapes in the structure of graphene flakes, which force electrons to “spin” more easily in one direction. Triangulene is a triangular graphene flake, which possesses […]
As important as remembering, it is forgetting. As Sherlock Holmes said the brain is like a room that you furnish with memories but where space is limited and unnecesary information should be erased. Much on how this erasing works is unkown, but a new study points out to a certain immune cell population in the […]
