Galaxies of life are collecting dust in museums – digitizing microscope slides can uncover billions of fossils for natural history

Pollen, algae, insects, radiolarians – each unique microfossil holds clues to how Earth has changed over millions of years. Combining AI with digital scanners helps researchers piece it all together.

Ancient viral genomes preserved in glaciers reveal the history of Earth’s climate – and how viruses adapt to climate change

From ice cores extracted from the Tibetan Plateau, scientists recovered the equivalent of 1,705 virus species. Reading their genomes tells the story of 41,000 years of climate change.

Horses lived in the Americas for millions of years – new research helps paleontologists understand the fossils we’ve found and those that are missing from the record

Horse fossils are abundant and widespread across North America. Scientists often use their long history to illustrate how species evolve in response to a changing environment.

Reconstructing ancient bacterial genomes can revive previously unknown molecules – offering a potential source for new antibiotics

Ancient microbes likely produced natural products their descendants today do not. Tapping into this lost chemical diversity could offer a potential source of new drugs.

Nocturnal dinosaurs: Night vision and superb hearing in a small theropod suggest it was a moonlight predator

By looking at the eye bones and ear canals of extinct dinosaurs, researchers show that a small ancient predator likely hunted at night and had senses as good as a modern barn owl.

What makes some species more likely to go extinct?

Death is inevitable for individuals and also for species. With help from the fossil record, paleontologists are piecing together what might make one creature more vulnerable than another.
