Having boys or girls is essentially random and doesn't depend on the parents' genes, researchers report.

A tube that mimics the pancreatic duct could help researchers "go back in time" to see how pancreatic cancer develops and spreads.

"This is like the Google Earth of endometrial cancer.… We tried to measure everything we possibly could. Then we searched for patterns."

A new "scorecard" that looks at 29 different genes could be a tool to improve cancer diagnosis. It may also help predict patient survivability.

The parasite witchweed is one of the greatest threats to food security in Africa. New research identifies how some sorghum crops resist it.

To study one of the last groups of woolly mammoths, researchers brought back some of their genes. The findings paint a grim picture of their slide to extinction.

Targeting the gene variant may be a way to fight the spread of harmful proteins in people with Parkinson's disease, researchers say.

The morning glory is both pretty and a noxious agricultural pest. New research looks into its genome to find out how it resists glyphosate, AKA Roundup.

Researchers created a DNA map of a domestic cat with Chédiak-Higashi syndrome to find the genetic cause behind the rare condition.

A life-threatening cytomegalovirus infection only affects one in a million healthy people—it's so rare, researchers have hardly had a chance to study it.
