Permineralized Jurassic fern rhizome from Korsaröd (Sweden) of Osmundastrum pulchellum. It has preserved Nuclei and Chromosomes, a fine subcellular detail has rarely been documented in fossils. It´s Rooted in DNA content was used to extrapolate relative genome, finding relationships with extant Osmundastrum cinnamomeum, and confirmed a monophyletic Osmunda. Osmundastrum pulchellum is one of the earliest fossil Osmundastrum rhizomes known so far, and the first of its kind from the Mesozoic of Europe. Its impressive preservation has lead to know even the biotic interactions with the Plant. It also has recovered the only know case know to preserve the ongoing mitosis processes in plant cells via calcification from volcanic hydrothermal brine.

These medieval graves looked like family burials. DNA told a different story
DNA Sweden
Ancient DNA shows that adults and children buried together in medieval Sweden were often not members of the same immediate family, suggesting that burial choices reflected more than biological kinship. The research also revealed early gender-based burial customs and uncovered the remarkable story of a young woman who may have completed a pilgrimage across Europe.

Plague was killing entire families thousands of years before the Black Death
DNA
Ancient DNA reveals that plague was already killing hunter-gatherers in Siberia 5,500 years ago, long before cities and flea-driven epidemics. The prehistoric strains may have been especially dangerous because they carried a genetic factor capable of provoking severe immune reactions.

DNA solves the mystery of a body found in the Arctic in 1859
DNA
Scientists have used DNA from living descendants to identify four more members of the doomed Franklin expedition, including Harry Peglar, whose identity had remained uncertain for 166 years. The findings offer new clues about the sailors who survived for years in the Arctic before joining the expedition’s ultimately fatal escape attempt.

Ancient DNA Rewrites Story of Enigmatic ‘American Cheetah’
Ancient DNA Rewrites Story of Enigmatic ‘American Cheetah’
DNA
For several decades, paleontologists have described Miracinonyx trumani -- an extinct species of cheetah-like felid that roamed the North American prairies and steppe terrains more than 13,000 years ago -- as North America’s answer to the African cheetah (Acinonyx jubatus). The post Ancient DNA Rewrites Story of Enigmatic ‘American Cheetah’ appeared first on Sci.News: Breaking Science News.

The secret hidden in these ancient manuscripts isn’t written in ink
DNA genetics
Researchers can now recover DNA from centuries-old parchment without damaging the manuscripts, turning historic documents into unexpected genetic time capsules. The hidden clues could reveal ancient trade routes, livestock history, manuscript origins, and details of everyday life stretching back more than a thousand years.
