Research institutions around the world house valuable genetic information that could help unlock countless medical mysteries. However, because DNA degrades over time, it is difficult for researchers to analyze DNA samples older than 20 years using conventional analytical approaches.

The research, the first of its kind, utilized ancient DNA data to explore human migration along the Hexi Corridor, a pivotal hub on the historical Silk Road. The results of the study, published in mid-December in the Science Bulletin, revealed two major migration waves in the past two millennia.

DNA and RNA sequencing, biomarker identification, and targeted therapies began being offered to cancer patients in the late 1990s and early 2000s and can take weeks. Each patient's unique biology demands a personalized cancer treatment because cancer does not wait.

A groundbreaking DNA study has unveiled a hidden chapter in human evolution, revealing that all modern humans evolved from two ancient and distinct groups. This research, published in March 2025, uncovers a deep ancestral structure shared by all contemporary populations,

The researchers behind the project stressed that none of these genetic conditions can justify or explain Hitler’s violent ideology or the atrocities committed during his rule.

A switch to a new technology made DNA analysis more accurate at the Bexar County Criminal Investigation Lab, but it also takes longer. That is prompting a larger backlog of cases. The lab is now responding in multiple ways.
