This paper describes and names a new reptile from the Early Permian (290 Ma) at the Richards Spur locality of Oklahoma. The new reptile provides a rare glimpse into the early stages of parareptile evolution and adds to the immense terrestrial tetrapod diversity found at Richards Spur.

Congratulations, Mark!

Two Hot Student Papers This Week!

The Thanksgiving edition of the Hot Student Paper series recognizes two recent papers by students in the MBiotech program, who are melding medicine and cutting-edge research.

Scheduled feeding alters the timing of the suprachiasmatic nucleus circadian clock in Dexras1-deficient mice

Food and the rhythms of life. To most of us this is just our daily routine, but to PhD student Pascale Bouchard-Cannon (Cheng Lab) this is cutting-edge research. Pascale recently published a paper in Chronobiology International. In this paper, she examines the role of the Ras-like G protein, Dexras1, in regulating circadian rhythms of mice under conditions of restricted food availability.  She finds that loss of Dexras1 expression in knockout mice sensitizes the SCN clock, the master circadian pacemaker, to the effects of restricted feeding, leading to greatly perturbed SCN-driven rhythms in the mutant animals. This work marks the identification of the first gene that is shown to be essential for buffering the SCN against the effects of restricted feeding.
