Swapping Bacteria May Help ‘Nemo’ Fish Cohabitate with Fish-Killing Anemones

A clownfish peers out of an anemone in a tank at Georgia Aquarium. Anemones usually sting, kill and eat fish, but not clownfish. Georgia Tech researchers found that the microbial colonies in the slime covering clownfish shifted markedly when the nested in an anemone. Could the microbes be putting out chemical messengers that pacify the fish killer? Credit: Georgia Tech / Ben Brumfield

Why the fish-killing anemone spares the clownfish is a scientific mystery that Georgia Tech marine microbiologists are now tackling in fish mucus.

Brittain Fellow Courtney Hoffman Publishes Chapter on Theatre Productions of Frankenstein

Hoffman's essay, "‘Now I am a Man!’: Performing Sexual Violence in the National Theatre Production of Frankenstein," in the collection Global Frankenstein was just released in ebook in October and print in November, 2018.

Synthetic Organelle Shows How Tiny Puddle-Organs in our Cells Work

In a vile three watery solutions phase separate into three layers. In membraneless organelles, chemical reactions occur at the interfaces of such layers, processing a reactant step-by-step and moving the reaction product from one layer to the next. Credit: Georgia Tech / Rob Felt

Just tiny puddles. That's what some of our cells' organelles are, and this synthetic organelle, engineered in the lab, shows how they can work.

Cheap fuel, cool temperatures, low material costs: This fuel cell could spread to homes and cars.

When Boy Fish Build Castles to Impress Girl Fish, Boy Genes Get a Rise

A special breed of cichlid fish has allowed researchers to match up gene activation with behavior. The up and down-regulation of genes may actually be steering ritual mating behaviors. The research is potentially useful in understanding autism since some genes involved in the fish behavior have human genetic cousins implicated in autism spectrum disorder.

Instinctive behavior may be directly driven be gene regulation, at least researchers were able to match the two up.

Tiny cancer signals of the glycoprotein sort evade detection, but they'll have a hard time dodging the new "chemical octopus."

Study Shows How Bacteria Behave Differently in Humans Compared to the Lab

More Workers Working Might Not Get More Work Done, Ants (and Robots) Show

To understand their strategies for working effectively without clogging traffic jams, researchers studied how fire ants dug tunnels in glass particles that simulated soil. (Credit: Rob Felt, Georgia Tech)

A new study shows that ants have a lot to teach robots about working in confined spaces.
