In a rapidly changing climate landscape, the plants we rely on for food, textiles and more face a multitude of challenges, ...

NASA astronaut Nick Hague runs an analysis with the miniPCR hardware for Genes in Space-6 during Expedition 59. This experiment explored how space radiation damages DNA and how cells repair that ...

Ion-nucleic acid interactions play essential roles in biological processes, because nucleic acids, including DNA and RNA, carry high-density negative charges (see a review in ref. 1). One important ...

Cells have evolved careful checks to ensure DNA is copied only once, but how they switch on replication at the right moment ...

DNA loop extrusion by structural-maintenance-of-chromosome (SMC) complexes has emerged as a primary organizing principle for chromosomes. The mechanism by which SMC motor proteins extrude DNA loops is ...

More than two months after the Artemis I launch, researchers are analyzing several scientific experiments that were on board. Some work is happening at the University of Colorado Boulder within the ...

Conventional cancer treatments, such as chemotherapy, often lack specificity and can damage both cancerous and healthy cells, ...

Scientists have discovered that a gene normally considered a DNA-protecting "good guy" can become dangerous when cells make too much of it. The gene, EXO1, acts like molecular scissors that help ...

Researchers who use nanopore-based DNA sequencing devices are scratching their heads over a recent announcement from Oxford Nanopore Technologies (ONT) that its flow cells work better in the dark. The ...

Astronaut Randy Bresnik explains why experiments are conducted on the International Space Station. Also check out a DNA experiment you can do in your classroom as Astronaut Kate Rubins shows us how to ...
