In this activity, students use an interactive tool to simulate how scientists collected and used sample data to estimate elephant population sizes.

Antonio was born with dystrophic epidermolysis bullosa, a rare genetic condition that causes blisters all over his body and in his eyes. He was blind for much of his life but can see again after getting gene therapy eyedrops.

New research suggests humans lived in South America at the same time as now extinct giant sloths, bolstering evidence that people arrived in the Americas earlier than once thought.

The first gene therapy for a deadly form of muscular dystrophy received preliminary U.S. approval on Thursday despite concerns from some government scientists about the treatment’s ability to help boys with the inherited disease.

An ancient human cousin may have buried its dead and carved symbols into cave walls, surprising findings for a creature with a small brain.

DNA is all around us — even in the air we breathe. Now scientists have found that air quality monitoring stations — which pull in air to test for pollution — also pick up lots of DNA that can reveal what plants and animals have been in the area.

Britain’s fertility regulator on Wednesday confirmed the births of the U.K.'s first babies created using an experimental technique combining DNA from three people, an effort to prevent the children from inheriting rare genetic diseases.

In this Click & Learn, students explore factors that contribute to patterns seen in the Keeling Curve: a continuous record of atmospheric CO₂ starting in 1958.

Doug Whitney inherited the same gene mutation that gave Alzheimer’s disease to generations of relatives by the average age of 50. Yet at 73, his mind is sharp. To scientists he offers a chance to learn how the body may resist Alzheimer’s.

Scientists are studying dogs around the Chernobyl nuclear power plant to see whether anything in their genes helped their families survive the harshest, most degraded environments.

As Latinos age in the Rio Grande Valley, the border region is experiencing a surge of dementia-related disease – pushing scientists to find out why.
