Trust your gut: The ins and outs of your gut microbiome

By SIMRAN DANG | February 18, 2025

Imagine a bustling metropolis on a weekday morning: vehicles honking, people rushing to work, street vendors setting up shop and delivery trucks weaving through the chaos. Despite the apparent asynchrony, there is order to this chaos. If we shrink this scene down to the microscopic level, we zoom into the gut microbiome, a dynamic and complex ecosystem teeming with trillions of microorganisms checking their own to-do lists to keep us alive.

The two selves: the immune system and cognition

By VICKY ZHU | February 7, 2025

"Who are you?" This question, in its many variations, is almost inevitable in school applications, job interviews or introspective moments. We spend years, perhaps our entire lives, unraveling the intricacies of who we are. But there exists another sense of self, of which many are unaware, that stands by 24/7 to protect us. It resides within us, a quiet but essential arbiter of identity: our immune system.

Science news in review: Feb. 2

By SHREYA TIWARI | February 2, 2025

Welcome to this week’s science news in review, where you’ll find newsworthy scientific innovations or events that have been revealed in the first month of 2025. Astronomers and space lovers across the country enjoyed a rare site throughout the month of January. After dark, stargazers could see Venus, Saturn, Jupiter and Mars. Venus and Saturn appeared in the southwest, Mars rose in the east and Jupiter was overhead. Uranus and Neptune would also be aligned. This incredible astronomical event will continue throughout February, where seven planets will be “aligned” in this way: Saturn, Mercury, Neptune, Venus, Uranus, Jupiter and Mars.
