Sweet potato DNA decoded, revealing hybrid ancestry. Discovery aids future breeding and resilience. The sweet potato is a staple food for millions of people worldwide, particularly in sub-Saharan Africa, where its ability to withstand climate Read More
A newly discovered Denisovan gene, hidden within human DNA, may have helped the first Americans adapt to their new world. Thousands of years ago, early humans braved a dangerous migration, traveling across vast stretches of Read More
For the first time, researchers have uncovered direct genomic evidence of the bacterium behind the Plague of Justinian—the world’s first recorded pandemic—in the Eastern Mediterranean, where the outbreak was first described nearly 1,500 Read More
DNA from rainwater provides a window into tropical canopy biodiversity
Tropical rainforests still represent a treasure trove of undiscovered species. While many species of plants, animals, and insects have been identified over the years, some parts of these tropical ecosystems are difficult to access and Read More
