Evolution is driven by changes in DNA that sometimes promote adaptation, altering traits like disease resistance or reproduction. Often, these changes are minuscule, modifying a single letter in the ...

Noninvasive prenatal testing (NIPT), which relies on cell-free fetal DNA in the mother's blood, is increasingly common. Yet two studies published online Apri 1 in the New England Journal of Medicine ...

Researchers at USC have developed a yeast model to study a gene mutation that disrupts the duplication of DNA, causing massive damage to a cell's chromosomes, while somehow allowing the cell to ...

A massive multiomics study of Atlantic salmon and rainbow trout shows that developmental constraints, particularly at the ...

A tiny freshwater snail from New Zealand is giving scientists a glimpse into evolution in motion. University of Iowa biologists have traced the snail's evolutionary history through its genome and ...

A new study shows that how a cell fails to divide after copying its DNA can determine its fate. Cell division is one of the most fundamental and complex processes underpinning life. In human cells, ...

What makes the human brain distinctive? A new study published July 21 in Cell identifies two genes linked to human brain features and provides a road map to discover many more. The research could lead ...
