Could mealworms help solve our plastic waste problem?

UdeM doctoral student Chloé Rosa-Teijeiro is studying how mealworms digest plastic and whether there are hidden risks to this promising approach to tackling plastic pollution.

Ce concept d'artiste représente une naine brune, un objet plus grand qu'une planète, mais pas assez massif pour déclencher la fusion de son noyau comme une étoile. Les naines brunes sont chaudes lors de leur formation et peuvent briller comme celle-ci, mais avec le temps, leur température se rapproche de celle des planètes géantes gazeuses comme Jupiter.

Illustration of LTT 9779 b, the only known ultra-hot Neptune. This planet orbits so close to its star that its atmosphere is scorching hot, glowing from its own heat while also reflecting starlight. Because it is tidally locked - always showing the same side to its star - one half is permanently in daylight while the other remains in darkness. New JWST observations with NIRISS reveal a dynamic atmosphere: powerful winds sweep around the planet, shaping mineral clouds as they condense into a bright, white arc on the slightly cooler western side of the dayside. As these clouds move eastward, they evaporate under the intense heat, leaving the eastern dayside with clear skies.
