Jeanne Calment

Jeanne Calment was indeed the world’s longest-living person

By combining epidemiology, mathematical modeling, and historical investigation, researchers in Geneva, Switzerland, and France confirm Jeanne Calment’s exceptional longevity, invalidating the conspiracy theories surrounding her.

How to optimize decision making?

UNIGE researchers demonstrate that our brains do not make decisions based on their inherent value but for what they offer above and beyond other possible propositions.
Photoreceptors cells responsible for colour vision. By sequencing one cell at a time, the researchers identified a gene (Rbp4) present in a small number of cells (in green). In purple, photoreceptors in which the Rbp4 gene is not activated.

Scientists unveiled the first steps in the construction of vision

By decoding the genetic mechanisms that control the neurons of the visual system, researchers at UNIGE are unveiling the first steps in the construction of vision, paving the way for regenerative eye medicine.

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...

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...
