Some genetic mutations that are expected to completely stop a gene from working surprisingly cause only mild or even no symptoms. Researchers in previous studies have discovered one reason why: cells ...

A new microfluidic chip simplifies detecting and quantifying DNA by analyzing electrical impedance signals that vary based on DNA flowing across a biosensor inside the chip. The proof-of-concept ...

From the time we are conceived and through old age, genetic mutations accumulate in all our tissues, eluding the body’s typically efficient DNA repair machinery and potentially affecting our health ...

After decades of fixating on mutations in nuclear DNA as the prime suspects in cancer development, researchers are increasingly peering into the cell’s powerhouse for clues. Mutations in mitochondrial ...

The DNA of Chernobyl cleanup workers showed mutations caused by radiation that were also evident in the genes of their ...

UCLA Health researchers have created a comprehensive map showing how eight different genetic mutations associated with autism spectrum disorder affect early brain development, providing new insights ...

Johns Hopkins Kimmel Cancer Center scientists report data from a new study providing evidence that random, unpredictable DNA copying "mistakes" account for nearly two-thirds of the mutations that ...

Circulating tumor DNA (ctDNA), small pieces of DNA released from dying tumor cells into the bloodstream, can be easily and non-invasively identified and examined through a simple blood test. This ...

Researchers have refined a powerful DNA sequencing tool that can uncover hidden mutations that occur naturally in our bodies as we age. In the largest study to date, they have used the tool to provide ...

An affordable new BRCA gene test has hit the market, but who should take it? — -- A new genetic testing kit that hits the market today is the most affordable, and arguably one of the simplest, ...

This module is a replica of a strand of DNA for eye color using light patterns controlled by an Arduino. The four light colors, red, green, blue, and yellow, represent the four nucleotide base pairs, ...
