The Evolution of Function within the Nudix Superfamily

John Srouji, Anting Xu, Annsea Park, Jack Kirsch & Steven Brenner
The Nudix superfamily encompasses over 80,000 protein domains from all three domains of life. These proteins fall into four general functional classes: isopentenyl diphosphate isomerases (IDIs), adenine/guanine mismatch-specific adenine glycosylases (A/G-specific adenine glycosylases), pyrophosphohydrolases, and non-enzymatic activities such as protein/protein interaction and transcriptional regulation. The largest group, pyrophosphohydrolases, encompasses more than 100 distinct hydrolase specificities. To understand the evolution of this vast number of activities, we assembled and analyzed experimental and structural data for 205...

Student Ratings of Teaching by Instructor Gender and Perceived Gender

Lillian MacNell, Adam Driscoll & Andrea Hunt
Student ratings of teaching play an important role in decisions about hiring, tenure, and compensation for instructors in higher education. In face-to-face classrooms, researchers are limited in their ability to test for the existence of bias in such ratings, as it is difficult to mask or misrepresent the gender of an instructor in the classroom. However, in the online environment is it possible to disguise an instructor’s gender identity, and therefore isolate the effects of...

Transcriptome Analysis Reveals Extensive Alternative Splicing-Coupled Nonsense-Mediated mRNA Decay in a Human Cell Line

Courtney French, Gang Wei & Steven Brenner
To further explore the regulatory potential of nonsense-mediated mRNA decay (NMD) in human cells, we globally surveyed the transcripts targeted by this pathway via RNA-Seq analysis of HeLa cells in which NMD had been inhibited. We first identified those transcripts with both a premature termination codon more than 50 nucleotides upstream of an exon-exon junction (50nt rule) and a significant increase in abundance upon NMD inhibition. Remarkably, at least 2,793 transcripts derived from 2,116 genes...

Confirmation of progressive plate motion during the Midcontinent Rift’s early magmatic stage from the Osler Volcanic Group, Ontario, Canada

Nicholas Swanson-Hysell, Angus Vaughn, Monica Mustain & Kristofer Asp
As the supercontinent Rodinia was assembling ca. 1.1 billion years ago, there was extensive magmatism on at least five Proterozoic continents including the development of the North American Midcontinent Rift. New paleomagnetic data from 84 lava flows of the Osler Volcanic Group of the Midcontinent Rift reveal that there was a significant and progressive decrease in inclination between the initiation of extrusive volcanism in the region (ca. 1110 Ma) and ca. 1105 ± 2 Ma...

Magmatic activity and plate motion during the latent stage of Midcontinent Rift development

Nicholas Swanson-Hysell, Seth Burgess, Adam Maloof & Samuel Bowring
The Keweenawan Midcontinent Rift of North America records significant continental rifting between ca. 1110 and 1085 Ma, and preserves the most detailed paleomagnetic record of plate motion of any continent in Precambrian time. U/Pb dates from extrusive and intrusive rocks of the western Lake Superior Basin suggest a latent stage of reduced magmatic activity from ca. 1106 to 1100 Ma that places constraints on the dynamics of rift development and the record of plate motion....

Six subsets of all native vascular plant species of California used by Baldwin et al. (2017), and the R script to use to extract the subsets from the master spatial file

Bruce G. Baldwin, Andrew H. Thornhill, William A. Freyman, David. D. Ackerly, Matthew M. Kling, Naia Morueta-Holme & Brent D. Mishler
Spatial patterns of diversity and endemism across California were examined by Baldwin et al. (2017 Amer. J. Bot.) for six subsets of all native vascular plant species: (1) only vascular plants that are completely restricted (absolutely endemic) to California, (2) only vascular plants native to the California Floristic Province, (3) only angiosperms, (4) only gymnosperms, (5) only ‘pteridophytes’ (i.e., ferns and lycophytes), and (6) the set of California species belonging to the diverse genera examined...

CUMV Amphibian Collection from Cornell University Museum of Vertebrates

John Friel
The CUMV Amphibian & Reptile Collection became one of the leading university based herp collections in North America during the first half of this century, largely because of the efforts of Professor Albert Hazen Wright and his wife, Anna Allen Wright. The major strengths of the collection, amphibians from the southeastern United States and both reptiles and amphibians from the Northeast, reflects the intensive collection by the Wrights. Much of the material collected by the...

Full vector low-temperature magnetic measurements of geologic materials

Joshua Feinberg, Peter Solheid, Nicholas Swanson-Hysell, Mike J. Jackson & Julie Bowles
The magnetic properties of geologic materials offer insights into an enormous range of important geophysical phenomena ranging from inner core dynamics to paleoclimate. Often it is the low-temperature behavior (<300 K) of magnetic minerals that provides the most useful and highest sensitivity information for a given problem. Conventional measurements of low-temperature remanence are typically conducted on instruments that are limited to measuring one single-axis component of the magnetization vector and are optimized for measurements in...
