Sharks in Acidic Waters Avoid Smell of Food

September 09, 2014 Atlanta, GA

The increasing acidification of ocean waters caused by rising atmospheric carbon dioxide levels could rob sharks of their ability to sense the smell of food, a new study suggests.

Sequencing of five African fishes reveals diverse molecular mechanisms underlying evolution

September 04, 2014 Atlanta, GA

Researchers have sequenced the genomes and transcriptomes of five species of African cichlid fishes and uncovered a variety of features that enabled the fishes to thrive in new habitats and ecological niches within the Great Lakes of East Africa.

With a few steps, cities can drastically reduce heat-related deaths

August 27, 2014 Atlanta, GA

The four-year study completed by Georgia Tech is the first major national assessment of the health of those who live in major cities, the impact of rising temperatures and what city leaders can do to alleviate the crisis.

A new study in Science showed that young fish have an overwhelming preference for water from healthy reefs. The researchers put water from healthy and degraded habitats into a flume that allowed fish to choose to swim in one stream of water or the other. The researchers tested the preferences of 20 fish each from 15 different species and found that regardless of species, family or trophic group, each of the 15 species showed up to an eight times greater preference for water from healthy areas.
