Cool Image: Tiny Bacterial Motor

Credit: Phillip Klebba, Kansas State University. It looks like a fluorescent pill, but this image of an E. coli cell actually shows a new potential target in the fight against infectious diseases. The green highlights a protein called TonB, which is produced by many gram-negative bacteria, including those that cause typhoid fever, meningitis and dysentery. …

Cool Tools: Pushing the Limits of High-Resolution Microscopy

Cell biologists would love to shrink themselves down and actually see, touch and hear the inner workings of cells. Because that’s impossible, they have developed an ever-growing collection of microscopes to study cellular innards from the outside. Using these powerful tools, researchers can exhaustively inventory the molecular bits and pieces that make up cells, eavesdrop …

The “Virtuous Cycle” of Technology and Science

Whether it’s a microscope, computer program or lab technique, technology is at the heart of biomedical research. Credit: Stock image. Whether it’s a microscope, computer program or lab technique, technology is at the heart of biomedical research. Its central role is particularly clear from this month’s posts. Some show how different tools led to basic …

Computational Biologist Melissa Wilson on Sex Chromosomes, Gila Monsters, and Career Advice

Dr. Melissa Wilson. Credit: Chia-Chi Charlie Chang. The X and Y chromosomes, also known as sex chromosomes, differ greatly from each other. But in two regions, they are practically identical, said Melissa Wilson , assistant professor of genomics, evolution, and bioinformatics at Arizona State University. “We’re interested in studying how the process of evolution shaped the …

What Zombie Ants Are Teaching Us About Fungal Infections: Q & A with Entomologists David Hughes and Maridel Fredericksen

I can still remember that giddy feeling I had seven years ago, when I first read about the “zombie ant.” The story was gruesome and fascinating, and it was everywhere. Even friends and family who aren’t so interested in science knew the basics: in a tropical forest somewhere there’s a fungus that infects an ant …

Feeling Out Bacteria’s Sense of Touch

Our sense of touch provides us with bits of information about our surroundings that inform the decisions we make. When we touch something, our nervous system transmits signals through nerve endings that feed information to our brain. This enables us to sense the stimulus and take the appropriate action, like drawing back quickly when we …

On Pi Day, Computational Biologists Share What They Love About Math

Another cool fact about Pi: The mirror reflection of the numbers 3 1 4 spells out P I E. Why do math lovers around the world call March 14 “Pi Day”? Because Pi, the ratio of a circle’s circumference to its diameter, is 3.14. Pi is a Greek letter (π) that represents a constant in …
