One of the hardest things when dealing with psychiatric illness is to come up with a clear diagnosis, but it seems that now it might be possible to diagnose schizophrenia just by analysing a certain biomarker in people’s hair. […]

The interactions between moving charges and magnetic fields can be quite complicated; more if we consider the quantum effects. One example is the collection of Hall effects.
Imagine that we have a conductor or a semiconductor through which a current […]

A collection of local magnetic moments arranged in a linear fashion that interact via some spin-spin coupling is generally known as a spin chain. This seemingly simple object is one of the most complex and rich physical systems that […]

 
Some people are cool not getting enough sleep. I am, however, not one of those. After almost two years of sleep deprivation I can say I am close to becoming the grumpy dwarf from Snow White.
And up until […]

Emotion recognition is the process of identifying human emotions. This is something that humans do automatically but computational methodologies have also been developed. Humans show universal consistency in recognizing emotions but also show a great deal of variability between individuals […]

Any physical law in which the magnitude of a physical quantity is proportional to the reciprocal of the square of the distance (1/r2) from the source of that property is known as an inverse-square law. Newton’s law […]

 

That female fertility is not stable during a woman’s lifetime is nothing new, but now a new study in the journal Science has found an explanation to its inverted U shape: chromosome errors!
This inverted U shape for female […]

A star cluster is a group of stars that are sufficiently close to each other for them to be physically associated. Stars belonging to the cluster are formed together from the same cloud of interstellar gas and have approximately the […]

Ladybugs are beautiful beetles and many present what is called an aposematic coloration, bright and striking colors that warn: do not eat me, I am dangerous. When they are disturbed, they defend themselves with legs and jaws, expel a poison […]
