Nature - Viral ribonucleoprotein–viral protein networks form pre-replication centres that nucleate viral factories and drive respiratory syncytial virus replication.

How the car-centric system perpetuates patriarchal violence — and why the electric transition threatens to make it worse.

The lab of Kris Burkewitz just made a key discovery: How cellular machineries are structured and organized within a cell has implications for healthy aging. “We didn't just add a piece to the puzzle—w...

As we age, our cells don’t just wear down—they reorganize. Researchers found that cells actively remodel a key structure called the endoplasmic reticulum, reducing protein-producing regions while pres...

Direct studies of long-term RNA virus evolution are largely limited to chemically-fixed specimens from natural history and pathology museums collected over the past two centuries. Detecting genomic traces of RNA viruses in older, buried remains is generally considered highly unlikely. The cold, dry conditions of Antarctica may represent an exception. Under such circumstances, natural mummification of penguins and seals—animals that form large colonies where RNA viruses circulate—is common and may facilitate the recovery of RNA virus genomes. Here, we show that Adélie penguin ( Pygoscelis adeliae ) mummies, ranging in age from recent to nearly two millennia, indeed contain fragments of such ancient viral genomes. Metatranscriptomic analyses yielded near-complete genome sequences of a picornavirus ( Megrivirus epengu ) and a rotavirus D ( Rotavirus deltagastroenteritidis ) from relatively recent specimens. We further retrieved rotavirus D sequences from a 280-year-old individual and a near-complete rotavirus G ( Rotavirus gammagastroenteritidis ) genome from a 1900-year-old one. These findings pave the way to direct studies of RNA virus evolution across millennia. ### Competing Interest Statement The authors have declared no competing interest.
