Review : lift at low Reynolds number

On November 20, 2023

In hydrodynamics, a lift phenomenon arises when a force acts on an object perpendicularly to its initial motion. In everyday life, we are familiar with this effect allowing for instance planes to take off or soccer balls to follow bent trajectories.

An acoustic "Tokamak"

On October 13, 2023

Thanks to 3D-printed cages, we've shown that bubbles can be stabilized in water in any shape: cubes, spheres, even rings. Here, we're printing a large number of 2cm ring bubbles, arranged on a large circle to create an acoustic tokamak.

The first kaleidoscope was made in the early 1800s by Sir David Brewster, who was seduced by the beauty of the patterns generated, both symmetrical and very complex. In a recent study carried out within the Grenoble Interdisciplinary Physics Laboratory (LIPhy - CNRS/UGA) and published in PNAS, scientists demonstrate that the kaleidoscopic effect, beyond its artistic function, can be usefully exploited by scientists. working with fiber optics.

Eight laboratories of the Mécabio Santé research group have shared their know-how and methods to study the influence of the storage and preparation of blood samples on the mechanical behavior of red blood cells. Published in the Biophysical Journal, this work has led to new recommendations to standardize practices and facilitate the comparability of measurements between laboratories.

Red blood cells bend for our health!

On February 6, 2023

Researchers have shown that the deformability of red blood cells is an essential ingredient for their homogeneous diffusion in the terminal network of blood vessels, when the diameter of the vessels is only slightly larger than the size of the cells.

Cell death and proteome dynamics

On January 16, 2023

Organisms have adapted to thrive in a narrow, well-defined temperature range. Humans are comfortable in ambient conditions, but other organisms can withstand much higher temperatures, even above the boiling temperature of water. How temperature kills a cell is not completely understood, but it is crucial in many ways. For example, to understand how life evolved on our planet, and how it can potentially develop elsewhere. We also need to consider how even small changes in temperature in the environment due to climate issues can throw the current distribution of living organisms out of balance. Finally, how therapeutic approaches can be optimized to kill cancer cells by locally increasing the temperature of the cells.
