Scientists have sequenced RNA from a nearly 40,000-year-old woolly mammoth leg, the oldest ancient RNA ever recovered. These ...

Cedars-Sinai scientists have created a new experimental drug called TY1 that helps the body repair damaged DNA and restore injured tissue. The discovery came from studying tiny molecular messages ...

Cedars-Sinai scientists have developed an experimental drug that repairs DNA and serves as a prototype for a new class of medications that fix tissue damage caused by heart attack, inflammatory ...

Thomas Gingeras did not intend to upend basic ideas about how the human body works. In 2012 the geneticist, now at Cold Spring Harbor Laboratory in New York State, was one of a few hundred colleagues ...

For the first time, researchers have uncovered Ice Age RNA preserved within permafrost mammoth tissue, offering a rare glimpse into real-time gene activity from tens of millennia ago. Researchers at ...

Scientists at the Nano Life Science Institute (WPI-NanoLSI), Kanazawa University, have discovered how a gene-regulating ...

NASA's OSIRIS-REx mission found ingredients for DNA and RNA on the asteroid Bennu. The discovery shows asteroids could seed planets with the precursors for life. It's also more evidence that life ...
