Squeezing cells into stem cells
EPFL scientists have developed a new method that turns cells into stem cells by “squeezing” them. The method paves the way for large-scale production of stem…
Using a microscopic ring to produce pulsed light
In general, light and water waves alike stretch out and dissipate as they move further and further away from their source. However, there is a type of wave…
The brain is not as cramped as we thought
To study the fine structure of the brain, including its connections between neurons, the synapses, scientists must use electron microscopes. However, the…
Faster, not stronger: How a protein regulates gene expression
Inside the cell, DNA is tightly coiled and packed with several proteins into a structure called “chromatin”, which allows DNA to fit in the cell while also…
Graphene meets heat waves
At the moment, however, potential applications are facing a fundamental problem: how does heat propagate inside these sheets of materials that are no more than…
Unraveling the light of fireflies
We know that this reaction needs oxygen, but what we don't know is how fireflies actually supply oxygen to their light-emitting cells. Using state-of-the-art…
