How I Got Here: A Webinar on Following Your Own Career Path

0 comments

There is no single avenue to a scientific career—the paths are as diverse as the people who pursue them. In a recent webinar, two NIGMS-supported researchers shared their unique journeys as scientists and their advice for those seeking careers in the field. The webinar is part of a series from NIGMS created for the research training community—students, postdocs, and faculty. Experts focus on topics from infectious disease modeling to virtual teaching and learning.

Scientist Interview: Studying the Biochemistry of Insects with Michael Kanost

1 comment

Insects vastly outnumber people on our planet. Some are pests, but many are key parts of their ecosystems, and some may even hold secrets for developing new materials that researchers could use in the medical field. Michael Kanost, Ph.D. Link to external web site, a professor of biochemistry and molecular biophysics at Kansas State University in Manhattan, Kansas, has been researching the biochemistry of insects for more than 30 years. His lab studies the tobacco hornworm, a mosquito that carries malaria, and the red flour beetle to better understand insect exoskeletons and immune systems.

Revealing a Piece of Cilia’s Puzzle

Cilia (cilium in singular) are complex organelles found on all of our cells except red blood cells. Their rhythmic beating moves fluid or materials over the cell to help transport food and oxygen or remove debris. For example, cilia in our windpipe prevent bacteria and mucous from traveling to the lungs. Some pick up signals like antennae, such as cilia in our ears that help detect sounds. One component of cilia is the doublet microtubule, a major part of cilia’s skeleton that gives it strength and rigidity.

Cilia: Tiny Cell Structures With Mighty Functions

Imagine an army of tiny soldiers stationed throughout your body, lining cells from your brain to every major organ system. Rather than standing at attention, this tiny force sweeps back and forth thousands of times a minute. Their synchronized action helps move debris along the ranks to the nearest opening. Other soldiers stand as sentries, detecting changes in your environment, relaying that information to your brain, and boosting your senses of taste, smell, sight, and hearing.

Your brain may be the commander in chief, but these rank-and-file soldiers are made up of microscopic cell structures called cilia (cilium in singular).

Here we describe these tiny but mighty cell structures in action.

Interview With a Scientist: Thomas O’Halloran, Metal Maestro

2 comments

Inside our bodies is a surprising amount of metal. Not enough to set off the scanners at the airport or make us rich, but enough to fill each of our cells with billions of metal ions, including calcium, iron, copper and zinc. These ions facilitate critical biological functions.

However, too much of any metal can be toxic, while too little can cause disease. Our cells carefully monitor and control their metal content using a whole series of proteins that bind, sense and transport metal ions.

Keeping tabs on why and how metals flow into and out of our cells is a passion of Thomas O’Halloran Exit icon, professor of chemistry and molecular biosciences at Northwestern University in Illinois. For the past three decades, O’Halloran has investigated how fluctuations in the amount of metal ions inside cells influence gene expression, cell growth and other vital functions. Using a variety of approaches, he has uncovered new types of proteins that bind metal ions and investigated the role that imbalances in these ions play in a number of disease-related physiological processes.

One recent focus of his studies has been how zinc regulates oocyte (egg cell) maturation and fertilization. Ultimately, his work could help us better understand infertility, cancer and certain bacterial infections.
