In contrast to those who resided in Siberia, Neanderthals who lived in what's now Belgium and France shortly before the ...

Doctors take a sample of the baby’s blood, usually by pricking its heel, and test for proteins and other markers associated with illnesses such as sickle-cell anemia or cystic fibrosis. The most ...

Deep within tropical forests, sloths move at a pace that seems almost frozen in time. Their slow movements, low energy use, ...

Scientists have long known that the DNA code in genes is not the only way to pass genetic traits from parents to offspring. "Epigenetic" marks—chemical modifications to DNA that don't change the DNA ...

The researchers analyzed the complete genomes of 18 cockroach and termite species. Termites and cockroaches are closely related and share common ancestors, but when they branched off from each other ...

Alzheimer's disease is a neurodegenerative disease characterized by a progressive decline in mental functions and memory loss. Along with frontotemporal dementia and some other neurodegenerative ...

We've been looking at nature the wrong way, argues Rowan Hooper. If we stop focusing on the individual, we get a whole new picture of how life on Earth – and elsewhere – may have begun ...

Genetic information in the DNA and modifications, such as DNA methylation, define the epigenetic landscape and phenotype and show both Mendelian and non-Mendelian heredity. Scientists have long known ...

Researchers headed by a team at Icahn School of Medicine at Mount Sinai have discovered that many gut bacteria use a flexible survival strategy—known as epigenetic “bet-hedging”—to withstand ...

Throughout history, most of the world's genomic research has relied on DNA data from people of European ancestry. A genome is the full DNA code of about 3 billion (a thousand million) bases, including ...

Countless scientists and at least a dozen high-concept sci-fi comedies over the past 30 years have speculated on the potentially degrading effect of making clones out of other clones, ad infinitum.
