A new robotic system at Georgia Tech’s Center for Chemical Evolution could soon let scientists better simulate and analyze the chemical reactions of early Earth on the surface of real rocks.
A new study of self-assembled silver-based structures known as superlattices has revealed an unusual and unexpected behavior: arrays of gear-like molecular-scale machines that rotate in unison when pressure is applied.
Researchers have shown that a process called DNA methylation can shield duplicate genes from being removed from the genome during natural selection. The redundant genes survive and are shaped by evolution over time, giving birth to new cellular funct
