Some animals that can’t manufacture their own chemical weapons feed on toxic organisms and steal their chemical defenses, having evolved resistance to them. One animal that does this is a sea slug that lives on the reefs surrounding Hawaii and dines on toxic Bryopsis algae. Marine scientists suspected the toxin is made by a bacterium that lives within the alga but have only just discovered the species responsible and teased apart the complex relationship between slug, seaweed, and microbe.
Exciting advances are likely to emerge from the 20-year-old field of engineering biology, or synthetic biology. Engineering biology/synthetic biology involves taking what we know about the genetics of plants and animals and then tweaking specific genes to make these organisms do new things. The field is now mature enough to provide solutions to many societal problems, according to a roadmap released on June 19 by the Engineering Biology Research Consortium.

An international group of microbiologists, including Georgia Tech's Frank Stewart, is warning that as science tries to search for climate-change solutions, it’s ignoring the potential consequences for climate change’s tiniest, unseen victims – the world’s microbial communities.
To celebrate the International Year of the Periodic Table, Tech students, faculty, and staff talk about their favorite elements. For June, we have Benjamin Breer, a physics major who just completed his first year at Georgia Tech.
When I volunteered for a study that will observe and measure movements during walking, I knew only that my participation would help researchers figure out how to make better prostheses for people missing limbs. I didn’t know that the experience would surface strong feelings of empathy for people with ambulatory problems.

Researchers have long known that when two galaxies approach each other and merge, the supermassive black holes at their centers form a pair and are eventually expected to merge as well. It is precisely these mergers that are considered one of the sources of the gravitational-wave background — a faint “hum” of spacetime detected in recent years. However, the role played by the geometry of the collision in this process has remained an open question.
Graduate student Sena Ghobadi of the Georgia Institute of Technology’s School of Physics, along with her colleagues, has developed three-dimensional dynamic models of such collisions.
