Senior Jacob Rosenthal (Biology) co-authors paper in GBE

About GBE
Congratulations to Jacob Rosenthal, who co-authored this article in Genome Biology and Evolution, an open access journal published by Oxford University on behalf of the Society for Molecular Biology and Evolution:

"Patterns of Population Variation in Two Paleopolyploid Eudicot Lineages Suggest That Dosage-Based Selection on Homeologs Is Long-Lived."

AUTHORS:  Hao, Yue; Washburn, Jacob D.; Rosenthal, Jacob; Nielsen, Brandon; Lyons, Eric; Edger, Patrick P.; Pires, J. Chris; Conant, Gavin C.

GENOME BIOLOGY AND EVOLUTION  Volume: 10  Issue: 3  Pages: 999-1011
DOI: 10.1093/gbe/evy061  Published: MAR 2018
Partial abstract: Genes that are inherently subject to strong selective constraints tend to be overretained in duplicate after polyploidy. They also continue to experience similar, but somewhat relaxed, constraints after that polyploidy event. We sought to assess for how long the influence of polyploidy is felt on these genes' selective pressures. We analyzed two nested polyploidy events in Brassicaceae: the At-a genome duplication that is the most recent polyploidy in the model plant Arabidopsis thaliana and a more recent hexaploidy shared by the genus Brassica and its relatives... Our results paint a picture of the long-lived effects of polyploidy on plant genomes, suggesting that even yesterday's polyploids still have distinct evolutionary trajectories.

Co-authors include researchers from North Carolina State University, Cornell University, Clarion University of Pennsylvania, Michigan State University, and University of Missouri.  As indexed in Web of Science.

New Books! So many, fantastic reading options. Take a look.

Catalog record on OBIS
So many new books have arrived in the past two months that we can't keep up with presenting them on our tumblr account.  Here are just two of the new book covers to entice you to view more, and look them up in OBIS.  Better yet, stop in the library and peruse the new book shelf!

Communicating science: two new books just received

Catalog record in OBIS
Hope Jahren, author of Lab Girl, is the guest editor of The Best American Science and Nature Writing, 2017.   Jahren is the recipient of three Fulbright Awards and is one of four scientists, and the only woman, to have been awarded both of the Young Investigator Medals given within the Earth Sciences.  Included among the essays is "Out Here, No One Can Hear You Scream," by Kathryn Joyce (Huffington Post).  It is an all too timely account of sexual harassment and hostility targeting women who work for various national and state agencies that protect America's natural heritage.

An essay by Elizabeth Kolbert, author of The Sixth Extinction and Field Notes from a Catastrophe, also appears in this volume.  "A Song of Ice" (from The New Yorker) recounts her visits to Greenland, where the effects of global warming are extraordinary and devastating.

 Catalog record in OBIS
All of the essays, as always in this series, are important reading.  Borrow the book over Winter Term - an essay a night will get you through the month of January with a lot to ponder.

Learn more about the science of science communication with this new handbook from Oxford University Press.  A key question considered in the handbook is: "What can we know empirically about the impact of the full range of scientists' linguistic choices and potential alternatives on public debate?"  Given the importance of scientific literacy (or at least realistic perceptions of scientists' work) for a healthy, just society, David Kirby's chapter on "The Changing Popular Images of Science" is very instructive.

Find these books on the new book shelf.
