Sequencing of five African fishes reveals diverse molecular mechanisms underlying evolution

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.

Evolution in Species May Reverse Predator-Prey Population Cycles

Atlanta, GA

Co-evolution in species may reverse traditional predator-prey population cycles, creating the appearance that prey are eating the predators.

This computer-simulated image shows gas from a star that is ripped apart by tidal forces as it falls into a black hole. Some of the gas is also being ejected at high speeds into space. Using observations from telescopes in space and on the ground, astronomers have gathered the most direct evidence yet for this violent process. (Credit: NASA, S.

Cosmic Slurp: Researchers Predict Signs of Black Holes Swallowing Stars

Atlanta, GA

Using theoretical and computer-based approaches, researchers are trying to predict the dynamics of how black holes devour stars.

Juvenile fishes from a carbon dioxide seep, such as damselfishes (pictured above), were less able to detect predator odor than fishes from a control coral reef, according to a new study in Nature Climate Change.

Fish From Acidic Ocean Waters Less Able to Smell Predators

Atlanta, GA

Fish living on coral reefs where carbon dioxide seeps from the ocean floor were less able to detect predator odor than fish from normal coral reefs, according to a new study.
