Carbon isotopes characterize rapid changes in atmospheric carbon dioxide during the last deglaciation.

Proceedings of the National Academy of Sciences of the United States of America

Bauska TK, Baggenstos D, Brook EJ, Mix AC, Marcott SA, Petrenko VV, Schaefer H, Severinghaus JP, Lee JE.
PMID: 26976561
Proc Natl Acad Sci U S A. 2016 Mar 29;113(13):3465-70. doi: 10.1073/pnas.1513868113. Epub 2016 Mar 14.

An understanding of the mechanisms that control CO2 change during glacial-interglacial cycles remains elusive. Here we help to constrain changing sources with a high-precision, high-resolution deglacial record of the stable isotopic composition of carbon in CO2(δ(13)C-CO2) in air extracted...

Does being female provide a neuroprotective advantage following spinal cord injury?.

Neural regeneration research

Datto JP, Yang J, Dietrich WD, Pearse DD.
PMID: 26692831
Neural Regen Res. 2015 Oct;10(10):1533-6. doi: 10.4103/1673-5374.165213.

It has been controversial whether gender has any effect on recovery following spinal cord injury (SCI). Past experimental and clinical research aimed at addressing this subject has led to constrasting findings on whether females hold any advantage in locomotor...

Reimchen hypothesized that pelvic reduction in threespine stickleback is favored by an absence of piscivorous fishes and the resulting increase in predation by insects, but Giles hypothesized that the predation regime is unimportant and that a low dissolved calcium...
