Good morning/afternoon wherever you are!

Today’s digest is really focusing on the environment- cilmate change (check the section right below), water, stone and coral reefs. We also included two microbiome framework papers worth reading and for all the athelates (and does who struggle to go the gym)- How is our microbiome linked to physical performance?

Have a good one!

Viruses and phages

Ribonucleotide reductases reveal novel viral diversity and predict biological and ecological features of unknown marine viruses – Eric G. Sakowski – PNAS USA

“We identify ribonucleotide reductase (RNR) genes as superior markers of viral diversity. RNR genes are distributed over a broad range of viruses”

More microbiology

Strength in Diversity – Daniel J. Wolter, Lucas R. Hoffman – Cell Host & Microbe

“In this issue of Cell Host & Microbe, Hammer et al. (2014) show that distinct, slow-growing bacteria have better in vitro and in vivo growth and virulence when cocultured than in isolation. “

When Racism Was a Science – ‘Haunted Files: The Eugenics Record Office’ Recreates a Dark Time in a Laboratory’s Past – Joshua A. Krisch – New York Times

“In its heyday, the office was the premier scientific enterprise at Cold Spring Harbor. There, bigoted scientists applied rudimentary genetics to singling out supposedly superior races and degrading minorities. “

Paul Ryan: Science doesn’t get climate change – Jane C. Timm – MSNBC

“A full 97% of researchers taking a stance on climate change say it’s man-made, as do 97-98% of the most frequently-published climate scientists. But according to Wisconsin Rep. Paul Ryan, they’re all wrong.”
