The science of human decision-making is only just being applied to machine learning, but developing a neural network even closer to the actual human brain may make it more reliable.

Neural networks do the opposite, making the same decisions each time. Now, Georgia Tech researchers in Associate Professor Dobromir Rahnev’s lab are training them to make decisions more like humans. This science of human decision-making is only just being applied to machine learning, but developing a neural network even closer to the actual human brain may make it more reliable, according to the researchers.

A groundbreaking new study published in Nature Physics has revealed that geometry influences biofilm growth more than anything else, including the rate at which cells can reproduce. The research shows that the fitness of a biofilm is largely impacted by the contact angle that the biofilm’s edge makes with the substrate.

Linda Green and Mary Peek

College of Sciences faculty Linda Green and Mary Peek were recently awarded Innovation Incubator grants to advance experiential learning in their courses. Peek's initiative in the Biochemistry Laboratory II class will enable students to engage in hands-on research, while Green's Urban Ecology students will focus on studying the impact of green infrastructure in urban settings.

Alex Robel, an associate professor in the School of Earth and Atmospheric Sciences at Georgia Tech, said pumping sand onshore is far from a perfect solution to stabilize a beach, but it’s “one of the best tools we have in our arsenal.”

“It’s been done in the United States for almost a century in different places and we know how to do it,” Robel said. “We’re good at it.”

But nourishment is only a Band-Aid for erosion. Once cities start replenishing sand, Robel said they have to keep doing it regularly.

A team of researchers including David Hu, a professor in Georgia Tech’s School of Biological Sciences and George W. Woodruff School of Mechanical Engineering, have visualized mosquito flight behavior for the first time.

Based on their data, the researchers said they don’t think mosquitoes swarm because they’re following the pack. Each appeared to pick up on the cues independently, then found themselves at the same place at the same time.

“It’s like a crowded bar,” said Hu. “Customers aren’t there because they followed each other into the bar. They’re attracted by the same cues: drinks, music, and the atmosphere. The same is true of mosquitoes. Rather than following the leader, the insect follows the signals and happens to arrive at the same spot as the others. They’re good copies of each other.”
