The results are transforming how scholars understand human history. By analysing parchment, researchers are uncovering ...
Animal life began in aquatic environments more than 600 million years ago. Around 500 million years ago, during the Cambrian ...
As climate change outpaces the ability of ecosystems to adapt, scientists are turning to conservation genomics to guide ...
A key feature of this process is natural competence, the ability of bacteria to take up free DNA from their surroundings. V. cholerae becomes naturally competent when it grows on chitinous surfaces, a ...
Researchers at the University of Minnesota Medical School have developed a new method called PARTAGE that provides a clearer ...
When bacteria cells replicate, they do so a little differently than human cells do. They don’t undergo mitosis, a splitting that involves construction of spindles to carefully separate the DNA after ...
