Microbes that flourish in boiling hydrothermal vents, bone-dry desert sediments, and radiation-blasted Antarctic rock are forcing scientists to rethink where life can and cannot exist. These ...

Late in 2025, we covered the development of an AI system called Evo that was trained on massive numbers of bacterial genomes. So many that, when prompted with sequences from a cluster of related genes ...

Add Yahoo as a preferred source to see more of our stories on Google. A Tokyo team built a neutral PEG-DNA complex that boosted gene expression in mouse muscle, avoiding cation-linked inflammation.

Every time a cell divides, it must copy its entire genome so that each daughter cell inherits a complete set of DNA. During that process, enzymes known as polymerases race along the DNA to copy its ...

For almost 60 years, scientists have tried to understand why DNA doesn’t replicate wildly and uncontrollably every time a cell divides – which they need to do constantly. Without this process, we ...

How much of our genome really matters? Some argue that because most of our DNA is active, it must be doing something important. Others say even random DNA would be highly active. This has now been put ...

The precise biological process behind the increased risk of melanoma previously remained unclear, and the study found the use of indoor tanning beds led to a nearly threefold increase in melanoma risk ...

In many submerged regions, murky mud shelters strange life-forms that seem to be the key to one of the biggest mysteries of life on Earth. These creatures belong to a domain of life called the archaea ...

A novel, blood-based test developed using fragmentomic features of cell-free DNA (cfDNA) detects colorectal cancer (CRC) with a 90.4% sensitivity and shows consistent performance across stages and ...

When cells proliferate, genomic DNA is precisely duplicated once per cell cycle. Abnormalities in this DNA replication process can cause alterations in genomic DNA, promoting cellular ageing, cancer, ...

The MCM helicase is broadly bound across the genome, and its phosphorylation is antagonistically regulated by the kinase DDK and the phosphatase RIF1–PP1. TRESLIN–MTBP recognises the phosphorylated ...
