New Study Examines Cellular, Molecular Differences Between Dengue, Zika More than two years after reports of skyrocketing Zika rates surfaced worldwide, questions still loom about this complicated virus. Florida State University researchers are one step closer to finding answers. In an article published today in the journal Stem Cell Reports, Professor of Biological Science Hengli […]

Florida State University senior Ivonne Mendieta has combined two unlikely subjects — biological science and religion — to foster a college experience that reflects her goal of becoming a physician. Mendieta’s relationship with religion began at a young age. She grew up around her family practicing different versions of Christianity and Catholicism while alternating living […]

When animals are isolated on an island, all bets are off as to how they will evolve and whether an animal will branch out into a new species. Australia has several types of kangaroos and Madagascar has many different lemurs. But just how much space a given species needs in order to evolve is a […]

FSU researcher: Ocean acidification means major changes for California mussels

Accelerating ocean acidification could be transforming the fundamental structure of California mussel shells, according to a new report from a Florida State University-led team of scientists. For thousands of years, California mussel shells have shared a relatively uniform mineralogical makeup — long, cylindrical calcite crystals ordered in neat vertical rows with crisp, geometric regularity. But […]

Researchers first to unlock key molecular mystery of premature aging syndromes

Published: November 27, 2017 | 4:00 pm | Posted in: Science & Technology

FSU postdoctoral researcher Juan Carlos Rivera-Mulia used an advanced approach to disease marker discovery developed at Florida State to conduct breakthrough research on premature aging diseases called “progeroid syndromes.”

New research from Florida State University is beginning to piece together the stubborn puzzle posed by a family of rare and debilitating premature aging disorders. Most of these diseases, called progeroid syndromes, share physiological symptoms characterized by the appearance of accelerated aging, such as skin disorders, loss of hair, skeletal and dental abnormalities and cardiovascular […]

Rival sperm and choosy eggs: FSU researcher finds that when sperm compete, eggs have a choice

The delicately mannered dance between discerning eggs and vying sperm is more complicated than scientists once believed, and it may hold secrets about the evolution of new species. In a paper published in the journal American Naturalist, Florida State University Chair and Professor of Biological Science Don Levitan investigates a root mystery in our scientific […]

Researcher reveals how beetles bounce back from forest fires

For decades, forestry services have used prescribed burns to promote ecological resilience in areas vulnerable to wildfires. Now, research from Florida State University has illuminated the piecemeal patterns of recolonization among a hardy species of beetle regularly affected by these managed burns. Using herbivorous tortoise beetle populations in Florida’s Apalachicola National Forest — where management […]
