Cyanobacteria—ancient microbes that oxygenated Earth and made complex life possible—are still revealing surprises billions of years later. Scientists have now discovered that a molecular system once used to separate DNA has been repurposed into something entirely different: a structure that shapes the cell itself.

The work demonstrates the power of ancient DNA to illuminate human biology and medicine in addition to history. A massive study of ancient DNA from nearly 16,000 people across more than 10,000 years in West Eurasia reveals that natural selection has shaped modern human genomes far more than previously thought.

Research on ancient DNA is surging, but how can scientists ensure that human remains of irreplaceable significance are preserved? This is the question investigated by an international research team led by the University of Bonn.

Scientists now recognize that spontaneous DNA errors, which we acquire in early development all the way until our last breath, can drive several ailments such as heart disease, autoimmunity, epilepsy, Alzheimer’s disease, and cancer. These errors could even be the missing piece in explaining the universal phenomenon of aging.

Tony Von Carruthers is set to be executed next month for the triple kidnapping and murder, but a new motion filed by the ACLU says crucial DNA evidence from the crime scene does not match with Carruthers and its retesting could prove his innocence.

Detectives used a clever gum ruse to collect DNA from Mitchell Gaff, who pleaded guilty to two decades-old cold case murders in Snohomish County court.

Research of the human genome has revealed an odd hidden code in our DNA. Ancient Astronaut Theorists believe this could be evidence of alien manipulation, in this scene from Season 13, "The Artificial Human.

Parrots captured in the Amazon rainforest by pre-Inca people were transported hundreds of miles over the Andes to coastal Peru where they were kept for their colorful feathers.
