Georgia State Geologists Unlock Mysteries of Ancient Climate Change

Researchers from Georgia State University’s Geosciences Department are using mineralogical tools to study climate change in East Africa that dates back nearly 1.9 million years ago. 

“Doing this research is exhilarating because you get a glimpse into how dynamic environmental change is on Earth,” said geosciences chair and Professor Daniel Deocampo, who is leading the… more »

In Sex-Changing Fish, Male-Typical Sexual Behavior Associated With Elevated Expression Of Male Sex Hormone Receptors In Muscles

Sex-changing fish exhibit differences in androgen receptor (AR) expression in muscles that are highly sensitive to androgens (male sex hormones) and essential for male courtship behavior, according to a Georgia State University study. 

Androgen signaling is a critical regulator of male-typical reproductive behavior in vertebrates. This study found androgen receptor expression is also important… more »

Georgia State Neuroscientists Rewire Brain Of One Species To Have Connectivity Of Another

Scientists at Georgia State University have rewired the neural circuit of one species and given it the connections of another species to test a hypothesis about the evolution of neural circuits and behavior. 

Neurons are connected to each other to form networks that underlie behaviors. Drs. Akira Sakurai and Paul Katz of Georgia State’s… more »
