Mitochondria lack nucleotide excision repair; however, mitochondrial DNA (mtDNA) is resistant to mutation accumulation following DNA damage. These observations suggest additional damage sensing or ...

A sample collected by the Hayabusa 2 spacecraft from the spinning top-like asteroid contained the nucleobases adenine, guanine, cytosine, thymine, and uracil. When you purchase through links on our ...

Even before the AI boom, data centers were already consuming staggering amounts of energy and natural resources. Now, generative AI has intensified that strain, exposing just how unsustainable our ...

Only a few years ago, Tuesday’s announcement that a glove believed to be connected to the disappearance of Nancy Guthrie in Tucson, Arizona, had no match in a DNA database would have been a dead end.

Scientists have discovered that DNA behaves in a surprising way when squeezed through tiny nanopores, overturning a long-held assumption in genetics research. What researchers once thought were knots ...

MIT researchers have found that tiny DNA loops persist even as cells divide, challenging the idea that the genome resets during mitosis. These structures may explain how cells retain genetic ...

In 1869, Swiss scientist Friedrich Miescher isolated a mysterious substance from cell nuclei—an overlooked finding that would later reshape biology and our understanding of life itself. A ...

The human genome has to be carefully organized so it will fit inside of the nuclei of cells, while also remaining accessible to the cellular machinery that works to express the right genes at the ...

The forensic examination of a murder victim has revealed that she had chimerism – meaning her body contained cells that were genetically distinct, as if they came from two different individuals. In ...

But what if the biggest giveaway that a text was written by AI isn’t a word, phrase, or punctuation mark, but a particular sentence structure instead? The idea that certain rhythms of sentences might ...

WASHINGTON — The U.S. Army announced updates to its Direct Commissioning Program, DCP, aimed at attracting top-tier professionals with specialized skills directly into its officer corps. The program ...
