About Margaux

Margaux’s early interest in health and how drugs work led her to a degree in Pharmaceutical Sciences. She’s currently pursuing a PhD using computational tools to design new drugs and study structural biology. She soon realised while practicing as a pharmacist how important science communication is when health professionals communicate with their patients, as this can have a significant impact on how they perceive and follow their treatment. She thinks Science provides an infinite source of wonder, and aims at sparking curiosity for interesting scientific stories thanks to breakers.

Margaux is the editor of 24 Breaks:

Distance-preserving moves always keep a point fixed

A fixed point is a point that does not move when subjected to a given transformation. Theorems guaranteeing the existence of such points have a wide application not only in mathematics, but also in economics or in Google's search engine. Such a new theorem has recently been discovered: every isometry has a fixed point when viewed in an extended space.

Keeping the balance: How epigenetics monitors cancer genes

Epigenetic regulation consists in chemical modifications on the proteins that organize DNA. Here, we show how it increases gene copies and rearranges the MLL gene, which associates with infant, adult, and therapy-associated leukemia. These findings show how chemotherapy-induced MLL changes occur and provide a therapeutic way to prevent them.

A resonance triggers chemical reactions between the coldest molecules

The rich energy structure of ultracold molecules (at -459 °F or -273 °C),  gives rise to collisional dynamics where the state-of-the-art models are inadequate for describing collisional resonances. We have discovered a pronounced magnetically tuned resonance in collisions between two NaLi molecules, which enhances the chemical reaction rate by more than a factor of a hundred.

How the immune response to a common virus may target the brain in multiple sclerosis

We discovered that the immune response to a common virus called Epstein-Barr virus may be linked to multiple sclerosis by cross-reacting with a protein in the body called alpha-crystallin B . People who reacted to this protein were more likely to develop the disease, and this finding is a step forward in our understanding of how this common virus may cause disease in some people.

What keeps trees grounded?

While exploring the root cause of trees' gravity sensing, the Morita lab stumbled upon proteins called ‘LAZY’ and dissected their association with the starch-filled packets in roots to dissolve a long-standing dilemma – is gravity sensed in terms of the force that the heavy starch-filled packets exert on the cell content or is it their position that send signals dictating where the Earth is?

Gas in distant galaxies: mixed or matched?

Gas is an essential ingredient of galaxies because it fuels star and planet formation. Studying this gas is important because it tells us how galaxies form, evolve, and interact with their environment. In this work we studied 64 small, distant galaxies and found that the gas is not well-mixed which tells us how it is moving in, out and around the galaxies.
