Traditional methods of preserving biological tissue samples require harsh treatments that make gene expression measurements, ...

Although there are striking differences between the cells that make up your eyes, kidneys, brain and toes, the DNA blueprint for these cells is essentially the same. Where do those differences come ...

Researchers from Children's Hospital of Philadelphia (CHOP) developed a new RNA sequencing strategy that can reveal how genetic variants disrupt gene function and improve the diagnosis of rare ...

A simple urine test developed by researchers at Stanford Medicine and the VA Palo Alto Health Care System can diagnose ...

Different types of cancer have unique molecular "fingerprints" which are detectable in early stages of the disease and can be picked up with near-perfect accuracy by small, portable scanners in just a ...

In most modern cells, DNA stores the genetic blueprint, and relies on proteins to replicate, repair and build from those blueprints. At the same time, proteins require instructions from DNA to be made ...

RNA and DNA are chemical cousins. But one tiny difference between them (an extra oxygen atom repeated along RNA’s backbone) ...

A newly revealed “aging cliff” in sperm RNA marks a conserved molecular transition from youth to later life, offering fresh insight into how a father’s age may influence the earliest stages of ...

Add Yahoo as a preferred source to see more of our stories on Google. (Christoph Burgstedt/iStock/Getty Images Plus) The RNA world hypothesis posits that molecules made up of ribonucleic acids (RNA) ...

The so-called ticking biological clock has been framed largely as a concern for women. We talk about egg freezing, ovarian reserve, and the ticking timeline of maternal fertility. Meanwhile, the male ...
