FSU researchers find tissue environment plays important role in tumor formation

A team of Florida State University researchers used a simple tumor model to show the importance of tissue microenvironment in primary tumor formation. In the journal Developmental Cell, FSU researchers explain how certain signaling pathways define tumor hotspots, tissue microenvironment favorable for tumorigenesis, and show that simple stimulation of a protein can lead directly to […]

Why fly the coop? With shortage of mates, some birds choose to help others raise offspring

It’s not uncommon for young adults to pitch in and help out with the care of younger siblings. But it turns out that sometimes birds choose to become avian au pairs rather than raise their own brood. After a five-year experiment, researchers from Florida State University and the Tallahassee-based Tall Timbers Research Station found that […]

FSU researchers discover a novel protein degradation pathway

Findings May Lead To Better Understanding of Muscular Dystrophy, Other Diseases The nucleus is a treasure trove of biological information that keeps the cell — and thus living organisms — ticking. But many processes within the nucleus remain a mystery to scientists. A Florida State University research team has uncovered one such mystery — how […]

FSU researchers unravel mystery of how, when DNA replicates

A team of Florida State University researchers has unlocked a decades-old mystery about how a critical cellular process is regulated and what that could mean for the future study of genetics. In cells, DNA and its associated material replicate at regular intervals, a process essential to all living organisms. This contributes to everything from how […]

FSU researchers update global record of medically significant scorpions

  Scorpions can be found at every corner of the globe and on six of the seven continents, from the southern tip of South America to the arid expanse of the Sahara Desert. That makes any rigorous accounting of the world’s venomous scorpions — and their various effects on human beings — an extremely tall […]

Scorpion census: FSU researchers update global record of medically significant scorpions

Scorpions can be found at every corner of the globe and on six of the seven continents, from the southern tip of South America to the arid expanse of the Sahara Desert. That makes any rigorous accounting of the world’s venomous scorpions — and their various effects on human beings — an extremely tall task. […]

FSU researcher: Family of rodents may explain how some groups of animals become so diverse

How did a single species of rodent invade South America and then quickly branch off into 350 new species? The answer is simple — the rodents were able to move quickly across the continent unencumbered by geographic boundaries that can’t be easily crossed such as an ocean. FSU Professor of Biological Science Scott Steppan and […]

Recent FSU graduate receives Phi Kappa Phi Fellowship

Recent Florida State University graduate Taylor Merritt has been awarded a $5,000 fellowship by The Honor Society of Phi Kappa Phi — the nation’s oldest and most selective collegiate honor society for all academic disciplines. Merritt is one of 57 recipients nationwide to receive a Phi Kappa Phi Fellowship. Merritt, a native of Pensacola, received […]

FSU research: Zika suppresses virus-fighting cells

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 […]

Ivonne Mendieta

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 […]

Worm-eating mice on small island hold clues to evolution

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 […]
