When we think about genetic inheritance, we usually leap to DNA, the four-letter code containing the instructions for building a living organism. Scientists know that DNA encodes everything from hair ...

A great part of living in the 21st century is that if you have a device that connects to the internet, you have access to hundreds, if not thousands of experts who are often eager to share in-depth ...

There is a fascinating feature of human genetics that makes the maternal line different from the paternal line. Every child receives genetic material from both parents, but mitochondrial DNA (mtDNA) ...

Forty years ago, a postdoctoral researcher named James McGrath who would go on to spend more than three decades as a clinical geneticist and research scientist at Yale, made a discovery that advanced ...

The COVID-19 pandemic gave us tremendous perspective on how wildly symptoms and outcomes can vary between patients experiencing the same infection. How can two people infected by the same pathogen ...

The program of Genetic Epidemiology and Statistical Genetics (PGSG) studies the genetic causes of complex human diseases. By uncovering the molecular mechanisms behind diseases, the program aims to ...

Me researchers analyzed results for nearly 6 million research-consented U.S. participants who received FDA-authorized Genetic Health Risk reports between 2017 and 2025. The reports cover 91 variants ...

Why do mitochondria matter to an egg? Mitochondria are responsible for producing ATP, the energy that cells need to function. An egg has a particularly high energy requirement as it matures, undergoes ...

Millions of years after an infection, viral DNA still influences how developing chimpanzee brain cells behave.

Most people with ALS don’t have a family history of it. Still, some cases of ALS are linked to inheriting specific gene mutations. Even nonfamilial cases can be linked to sporadic gene mutations that ...
