Researchers have analyzed ancient DNA from Borrelia recurrentis, a type of bacteria that causes relapsing fever, pinpointing when it evolved to spread through lice rather than ticks, and how it gained ...

The genome structure—how genes are organized within DNA sequences in an organism—is fundamental to the processes and functions of organisms.

Researchers at the Francis Crick Institute and UCL have analyzed ancient DNA from Borrelia recurrentis, a type of bacteria that causes relapsing fever, pinpointing when it evolved to spread through ...

A team at the University of Tokyo has developed a system to control and accelerate the evolution of changes in bacterial genome structure, targeting small "jumping genes," or DNA sequences known as ...

To better understand the circadian clock in modern-day cyanobacteria, a research team has studied ancient timekeeping systems. They examined the oscillation of the clock proteins KaiA, KaiB, and KaiC ...

GDA constitutes an important adaptive mechanism in bacteria, and resistance to several ... and describe how they can facilitate adaptive evolution in response to toxic drugs.

Scientists have discovered a new type of immune defense in E. coli bacteria that turns viral infection machinery against the virus itself. Named after the Chinese military strategist Kongming—who ...

Matt Lyman, a staff scientist at Lawrence Livermore National Laboratory (LLNL) in the Biosciences and Biotechnology Division, ...
