Understanding the ‘fundamental nature’ of atomic-scale defects
New research provides a deeper mathematical understanding of the dynamics of a material’s atomic-level defects, which could enable new ways to imbue substances with unique and desirable properties.
A shaky future for U.S. transit systems, and why we need to save them
The pandemic lockdown in cities has impacted transit systems around the world. While the federal stimulus package includes transit agencies, experts at Kleinman Center for Energy Policy argue that the decrease from local and state sources could be substantial.
Life, death, and the Amazonian litter layer
Kristina Lyons’ new book explores the Colombian world of litter layers, seeds, and soils; Amazonian farmers, narcos, and the War on Drugs
Using stress to shape microlevel structures
A new study describes how external forces drive the rearrangement of individual particles in disordered solids, enabling new ways to imbue materials with unique mechanical properties.
A new tool for cell biologists
Researchers describe a new approach for creating realistic synthetic cells, providing a new tool that can be used to figure out how certain pathogens, such as SARS-CoV-2, infect hosts.
Cavity-causing bacteria assemble an army of protective microbes on human teeth
Examining bacteria growing on toddlers’ teeth, a team from the School of Dental Medicine and Georgia Tech found that the microbes’ spatial organization is crucial to how they cause tooth decay.
PEP winners connect patients with the medicines they need
Aarogya, a social-enterprise nonprofit created by three President’s Engagement Prize winners and graduating seniors, will bring affordable medicines to low-income people living in India.
At home, but still engaged with STEM classes
While instructional laboratories on campus are closed, students, faculty, and instructors are finding creative solutions for science, math, and engineering courses and projects.
To err is human, to learn, divine
Researchers develop a new model for how the brain processes complex information: by striking a balance between accuracy and simplicity while making mistakes along the way.
