Discovery of a Splicing Regulator Required for Cell Cycle Progression
Here we describe a new G1 mutant from an ancient family of apicomplexan protozoans. Toxoplasma gondii temperature-sensitive mutant 12-109C6 conditionally arrests in the G1 phase due to a single point mutation in…

Alpha7 Neuronal Nicotinic Receptors as a Drug Target in Schizophrenia
Preclinical and clinical data suggest that neuronal α7nAChRs play an important role in cognitive functions. Moreover, some, but not all, early clinical trials conducted with α7nAChR agonists show cognitive benefits…

The Tissint Martian Meteorite as Evidence for the Largest Impact Excavation
Here we show that the Tissint meteorite, a 2011 meteorite fall, contains virtually all the high-pressure phases (seven minerals and two mineral glasses) that have been reported in isolated occurrences…

Characterization of a Diffusible Signaling Factor from Xylella Fastidiosa
We describe here the isolation and characterization of an X. fastidiosa DSF (XfDSF) as 2(Z)-tetradecenoic acid. This compound was isolated both from recombinant Erwinia herbicola expressing X. fastidiosa rpfF and…
