Scientists at LIPhy have demonstrated the existence of a behavioral transition when the environment of zebrafish becomes too crowded, showing the extent to which the collective school structure resists the structural complexity of the surrounding environment.

An artificial pancreas
On July 2, 2024
A new implantable pancreatic bioreactor device has been developed by the SyNaBi team in the TIMC laboratory (Translational Innovation in Medicine and Complexity), in collaboration with Grenoble Alpes University Hospital and the LIPhy (3D printing) and LBFA (Laboratory of Fundamental and Applied Bioenergetics) laboratories.

Matostheque
On July 2, 2024
The "matostheque" is an online tool for reserving small items of materials. Materials owners add the characteristics and availability of their material to the database. Users can then make a loan request, specifying the dates.

The study and understanding of the collective movement of animals is a topic of interdisciplinary interest that has long attracted the attention of many scientists (in statistical physics, hydrodynamics, ethology, biology, sociology, and now even in the strongly emergent field of robotics).

An international team has shown that the’ buckling instability of’a layer of lipids deposited on the surface of’a microbubble produces a propulsion force that can lead to displacements of the order of m/s, of the’, a promising discovery for applications in the medical field.
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.

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.

Influence of storage and buffer composition on the mechanical behavior of flowing red blood cells
On March 10, 2023
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.

Probe the mechanics of biological tissues using their own cells as actuators
On February 28, 2023
By combining tissue engineering and optogenetics, biophysicists have transformed cells into biological microactuators in order to study the spatio-temporal propagation of mechanical signals in biological tissues and to characterize the architecture and viscoelastic properties of these tissues.

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.

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.
