RNA, widely known from the COVID-19 vaccine, is not actually a "therapeutic agent," but a technology that delivers the ...

Professor Indraneel Mittra and his team show that DNA fragments from dying cells function as agents of horizontal gene transfer in mammalian cells. For decades, scientists have known that bacteria can ...

The ancient DNA fragments come from a Greenland ecosystem where mastodons roamed among flowering plants. It may hold clues to how to survive a warming climate. After an eight-year effort to recover ...

The universal features that define genomic regions acting as replication origins remain unclear. In this study, we mapped a set of origins in Trypanosoma brucei using stranded short nascent strand ...

DNA fragments recovered from an ice sheet in northern Greenland represent the oldest DNA ever found, a group of Danish scientists reported December 7, 2022 in Nature. The team dated the samples to ...

Researchers have developed a new machine-learning model to detect cancers that are in their early stages of disease by examining DNA fragments from cancer cells in the blood. A University of ...

Platelets are probably best known for their role in blood clotting, making scabs and related, if less salubrious, contributions to heart attacks and strokes. But these tiny, saucer-shaped blood cells ...

In the past few years, gel electrophoresis of DNA fragments has become an important complement to hybridization and amplification sequencing tools. As variations on PCR, RFLP, mutation sequencing, and ...

A mammoth tooth reveals bacterial DNA from 1.1 million years ago, offering new clues about diseases and hidden ecosystems in ...

Every household dog, from a towering Great Dane to a trembling toy breed, traces back to wild wolves. New genetic work shows ...
