Neww research from the University of Georgia has identified the critical role a particular type of protein – known as histone – plays in archiving information from past viral threats and contributing to more effective immune responses to future threats, through what is called genetic immunity.
Histones are highly conserved proteins that have been compared to spools around which strands of DNA wrap themselves. A research team led by Michael Terns…
Molecular scale breakthroughs in human health – from COVID-19 vaccines to cancer therapeutics – require scientists to understand how molecules interact with each other, akin to figuring out how puzzle pieces fit together. To do this, scientists use a special microscope called an atomic force microscope (AFM) that can see and manipulate molecules. For the virus that causes COVID-19, for example, this microscope can gently poke and measure…
DNA activity can change without changing the sequence of the DNA segment itself. Gene activation and inactivation can be the basis for how species produce unique individuals. Some processes that change gene activity are well understood in the context of model species. However, scientists are still grappling with how some processes, like DNA methylation, change gene activity in many diverse organisms. Broader theories applicable to all species…
Researchers in the UGA department of plant biology have published the first genetic linkage map for what has long-been an object of human fascination: plants that have evolved the capacity to capture and digest insects. Lead author Russell Malmberg explains:
"We normally think of plants as being eaten by animals, but a small number of plant species have reversed this and are able to capture and digest insects. These…
Distinguished Research Professor Kelly Dawe in the department of genetics is principal investigator on a new project to sequence the genetic diversity of the world's largest cash crop:
When the human genome was first sequenced in 2001, the project focused on a single individual. Since that time, several new genomes have been assembled and additional genetic data have been generated for thousands of individuals, producing a more complete picture…
Marshall Scholar and Franklin College alumnus Matt Sellers (BA ’12) recently attended a reception with Prince Charles, the Prince of Wales and Honorary Patron of the Association of Marshall Scholars, to celebrate the 60th anniversary of the Marshall Scholarships.
At the reception, held at the Foreign and Commonwealth Office in London, the Prince of Wales awarded several Marshall Medals to individuals of outstanding achievement. The event…
