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.

The study confirms laboratory experiments showing that the behavior of reef fishes can be seriously affected by increased carbon dioxide concentrations in the ocean. The new study is the first to analyze the sensory impairment of fish from CO2 seeps, where pH is similar to what climate models forecast for surface waters by the turn of the century.

From time to time, living cells will accidently make an extra copy of a gene during the normal replication process. Throughout the history of life, evolution has molded some of these seemingly superfluous genes into a source of genetic novelty, adaptation and diversity. A new study shows one way that some duplicate genes could have long-ago escaped elimination from the genome, leading to the genetic innovation seen in modern life.

Research in the Gaucher group provides evolutionary insights into why humans develop gout. By inferring and resurrecting ancient sequences for an enzyme called uricase, the group was able to determine when and why the enzyme stop functioning in apes (including humans) while remaining functional in most other mammals. See the following link for an insightful article written by National Geographic: http://phenomena.nationalgeographic.com/2014/02/17/a-resurrected-cretaceous-answer-to-the-disease-of-kings/

If a driver is traveling to New York City, I-95 might be their route of choice. But they could also take I-78, I-87 or any number of alternate routes. Most cancers begin similarly, with many possible routes to the same disease. A new study found evidence that assessing the route to cancer on a case-by-case basis might make more sense than basing a patient’s cancer treatment on commonly disrupted genes and pathways.

Exploiting the use of DNA single- and double-strand breaking forms of the I-SceI endonuclease to stimulate homologous recombination and gene targeting in budding yeast and in human cells, the research of Samantha S. Katz in Francesca Storici’ lab provides new mechanistic insights into the process of nick-induced DNA recombination and on the function of nicking enzymes in genetic engineering.

Taking a DNA molecule into the vicinity of a homologous target gene by a DNA aptamer provides a many-fold enhancement of gene correction frequency at that genetic locus. Aptamer-guided gene targeting, or AGT, is a novel approach for genetic engineering developed by Patrick Ruff in Francesca Storici’s group.

Competition may have a high cost for at least one species of tropical seaweed. Researchers examining the chemical warfare taking place on Fijian coral reefs have found that one species of seaweed increases its production of noxious anti-coral compounds when placed into contact with reef-building corals, but at the same time becomes more attractive to herbivorous fish.

Georgia Tech faculty continue to be recognized as among the most respected in their field. Last month, the American Association for the Advancement of Science (AAAS) named four — in biology, computing and engineering — to its 2013 class of fellows
