How chronic liver diseases cause molecular changes in the brain?

Scientists found that molecular changes affect the brain as early as the second week of liver disease. And yet, the rats have minimal symptoms of the disease.

Scientists confirmed the theory of very strong magneto-optical resonance in graphene

Controlling infrared and terahertz waves using magnetic and electric fields is one of the extraordinary difficulties in physics that could revolutionize optoelectronics, telecommunications, and...

Medicines made of gold nanoparticles to help the immune system

Nanotechnology is helping to considerably improve, even revolutionize, many technologies and industry sectors: information technology, homeland security, medicine, transportation, energy, food safety, and environmental...

What triggers the Schizophrenia?

Schizophrenia, a severe mental illness, in which patients decipher reality strangely or let's say abnormally. For them, the world is a cluster of confusing...

Music strengthens the development of brain networks of very premature babies

Almost 1% of children are born very prematurely in Switzerland. However, recent advances have offered them a good chance of survival, still, the children...

Five planets revealed after 20 years of observation

The first evidence of an exoplanet was noted in 1995. A giant planet was found in a four-day orbit around the nearby star 51...

Necrophagy: a means of survival in the Dead Sea

Studying organic matter in sediments helps shed light on the distant past. What was the climate like? What organisms populated the Earth? What conditions...
The electroencephalogram records the electrical activity of the brain in a non-invasive way using 256 electrodes placed on the scalp. Thanks to mathematical algorithms combined with anatomical imaging, we can see what is happening in the deepest part of our brain, without having to enter it directly. © UNIGE

A gentle method to unlock the mysteries of the deep brain

The Subcortex regions of the brain are located below the cerebral cortex and completely covered by it. As they are located in the deepest...

The physical forces of cells in action

Detecting physical force is quite difficult. Imaging the physical forces that act in living cells remains one of the main mysteries of current biology....
