Inside the latest issue of Spartan Science
Science is rarely a story of isolated moments; it is an evolving tapestry woven from decades of curiosity and dedicated problem-solving. The latest edition of Spartan Science, the magazine from Michigan State University's College of Natural Science, brings this reality into sharp focus.
Whether you are fascinated by climate resilience, human physiology, or the genomic secrets of ancient creatures, this collection offers a window into science driven by purpose. Here is a closer look at three standout stories featured in the latest issue:
How to Survive a Drought
As global weather patterns become increasingly unpredictable, securing the world's food supply is one of the 21st century's defining challenges. MSU plant biologist Thelma Madzima is on the frontlines of this fight. Her research investigates how crops respond to environmental stress—specifically extreme drought—at the molecular level.
By exploring how gene expression changes without altering the underlying DNA sequence, Dr. Madzima’s lab seeks to understand how plants "remember" stress and adapt. This work holds immense promise for breeding climate-resilient crops capable of thriving in warming, water-scarce environments.
An Evolutionary Treasure
How can an ancient fish help us understand human health and development? Enter the spotted gar (Lepisosteus oculatus), a "living fossil" that has remained largely unchanged for millions of years.
Researcher Ingo Braasch and his team are leveraging the spotted gar’s unique genome to bridge the evolutionary gap between teleost (modern ray-finned) fish and land vertebrates, including humans. Because popular biomedical model organisms like zebrafish underwent an extra genome duplication event during evolution, their genetic pathways can be tricky to map directly to humans. The gar lacks this extra duplication, serving as a clean Rosetta Stone that clarifies how human genes evolved and function in health and disease.
The Search for Next-Gen Weight Loss Drugs
While metabolic health and weight management are major public health topics, current therapeutic options do not work identically for everyone and often come with side effects. Physiology professor Gina Leinninger is diving deep into the brain circuitry that governs hunger, metabolism, and satiety.
Dr. Leinninger’s lab identified specific brain peptides that regulate appetite and body weight without triggering adverse side effects. Crucially, her team is also exploring how these neural pathways interact with weight-related pain, opening up exciting possibilities for holistic, next-generation metabolic treatments.
