Origins of metastasis
Origins of metastasis
Researchers at the University of Geneva show that the experience of impending cell death within a primary  tumour can lead to the development of «pro-metastatic» cells. Metastatic cells form in a primary tumour and then break away from it, migrate to other organs, attach to them and form new tumours.

Physics and biology explore together the mechanisms of life
Physics and biology explore together the mechanisms of life
Researchers created a model to disentangle how proteins are unevenly distributed in cells, a process at the very basis of the development of living beings. Each of our cells contains about 40 million proteins that together perform all the tasks the cell needs to survive. For a smooth action, the right proteins must be concentrated in specific amounts, at a specific time and at a specific location.

The role of lipids in the development of Alzheimer's disease
The role of lipids in the development of Alzheimer’s disease
A European consortium coordinated by UNIGE shows how a mutation in the APOE protein changes the lipid transport in the brain and could promote the arise of Alzheimer's disease. Neurons in the brain coexist with and rely on many other cell types to function properly. Astrocytes, which take their name from their star shape, ensure the survival of neurons by feeding and detoxifying them with the help of a multifunctional protein, APOE.

Inciting instead of coercing, 'nudges' prove their effectiveness
Inciting instead of coercing, ’nudges’ prove their effectiveness
A team from the UNIGE demonstrates that certain soft incentive techniques, known as «nudges», are effective in getting people to change their behaviour. To get through challenges such as the pandemic or the climate change, citizens must change their habits and behaviors. But how can this be achieved without resorting to coercive measures? The answer to this question may be the «nudges» that have been gaining popularity over the last decade.

The unexpected benefits of fat in type 2 diabetes
The unexpected benefits of fat in type 2 diabetes
Scientists from the University of Geneva have discovered that fat may help the pancreas adapt to excess sugar, thereby slowing down the onset of diabetes. With nearly 10% of the world's population affected, type 2 diabetes is a major public health issue. An excessively sedentary lifestyle and a too-caloric diet encourage the development of this metabolic disease by altering the functioning of pancreatic cells and making blood sugar regulation less effective.
