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 21 Breaks:

The diurnal habits of a long-gone Tibetan Owl

Owl’s nocturnal habits stand out from most birds, and in various cultures they are associated with wisdom or even the magical world of Harry Potter. We describe here a unique fossil of an extinct owl species that was instead active during the day. This species links to some of the few daytime active owls and fills in a six-million-year gap in their evolutionary history.

Mathematical modeling and tumor avatars: What’s the link?

We introduce a new approach for designing personalized treatment for colorectal cancer patients, by combining patient-derived samples and mathematical modeling. This unique strategy is tailored specifically to individual patients, as we go from bench to bedside and back.

A mysterious object in our Galaxy pulses every 76 seconds

The discovery of an ultra-long period neutron star, emitting unusual radio signals is rewriting our understanding of these unique star systems. The source has been found to reside in a neutron star graveyard and yet still produce radio emission (zombie stars!). It exhibits highly unusual and chaotic pulse shapes quite unlike anything seen in known neutron stars.

The missing galaxies in the early universe

Faraway galaxies are hard to detect, not only because they appear fainter, but also because the light that we detect from them is infrared. Many of these objects were invisible to us until the James Webb Space Telescope was launched. With this new telescope, scientists discovered 33 new galaxies in the early universe. This opens the door for James Webb to find many new galaxies.

Marsquakes redefine what we tought about a quiet Mars

Analyzing seismic waveforms recorded by the InSight mission seismometer, we discovered and documented 47 marsquakes in the Cerberus Fossae region of Mars. Their repetitive nature at all times of the Martian day tells a story of their likely volcanic origin and of a mobile Martian mantle. Mars harbours a liquid core, and it remains to be understood why the Martian geodynamic field ceased to exist.

The Light of Earendel – The Most Distant Star Yet Observed

The gravity of massive objects can magnify background objects, making them appear larger and brighter. Precise alignment between a background star and a foreground lens leads to extreme magnifications, allowing individual stars to be detected at great distances. This technique has recently revealed the most distant star yet observed, which existed when the universe was only 900 million years old.
