The oldest DNA ever discovered reveals a thriving ecosystem lost to time

The oldest DNA ever discovered reveals a thriving ecosystem lost to time Scientists have identified the oldest DNA ever discovered, revealing a complex ecosystem that existed in modern-day Greenland two million years ago, according to the results of a new study published in the journal Nature. The double-helical molecule of deoxyribonucleic acid (or DNA for …

Webb telescope reveals a luminous stellar crime scene

Webb telescope reveals a luminous stellar crime scene 2,500 years ago, one of the most beautiful features of space emerged: the Southern Ring Nebula. The nebula was vividly imaged earlier this year by the Webb Space Telescope, and astronomers now think they know exactly how a star’s violent outburst occurred and left the elegant nebula …

Oldest DNA sequenced to date shows mastodons once roamed a warmer Greenland

Oldest DNA sequenced to date shows mastodons once roamed a warmer Greenland Enlarge / An attempt to reconstruct what Northern Greenland looked like about 2 million years ago. When ever living tissue is kept in a cold, dry environment, fragments of DNA can survive for hundreds of thousands of years. In fact, DNA doesn’t even …

New kilonova makes astronomers rethink what we know about gamma-ray bursts

New kilonova makes astronomers rethink what we know about gamma-ray bursts Enlarge / Artist’s impression of GRB 211211A. The kilonova and gamma ray burst is on the right. Aaron M. Geller/Northwest/CIERA A year ago, astronomers discovered a powerful gamma-ray burst (GRB) lasting nearly two minutes called GRB 211211A. Now that unusual event turns the long-standing …
