Art and science come together to highlight the beauty and fragility of plankton in alpine lakes.

At the heart of the Arabidopsis thaliana flower, the pistil, formed of hundreds of papillae and an ovary housing the ovules, is surrounded by stamens that release pollen grains carrying male gametes. In an article published in PLOS Computational Biology, scientists combine theory and experiments to reveal how male gametes are guided toward the ovules from the very beginning of their journey on the surface of the female reproductive organ.

A team from LIPhy has studied the transport of CO2 within a liquid foam in contact with the atmosphere and shown how its effective diffusion in the medium emerges from the coupling between the structure of the foam and the transport of the gas through the soap films. This study paves the way for the development of low-cost CO2 filtration systems based on the ability of this main contributor to the greenhouse effect to dissolve more easily in water than most other gases.

LIPhy is taking action to reduce the share of equipment purchases in its CO2 emissions! Over the past year, the laboratory has developed and implemented a new digital tool for sharing equipment: the Matosthèque.
