Phytochrome: If It Looks and Smells Like a Histidine Kinase, Is It a Histidine Kinase?

second domain contains two PAS repeats (Lagarias et Like all organisms, plants continually monitor and real., 1995) that overlap with newly identified motifs, the spond to changes in their environment. Being photosynS boxes, that occur in a large family of energy-sensing thetic, plants are particularly attuned to ambient light proteins including other histidine kinases (Zhulin et al., condition...

If it looks and smells like the reals

Given a topological space < X, T > ∈ M, an elementary submodel of set theory, we define XM to be X ∩ M with topology generated by {U ∩ M : U ∈ T ∩ M}. We prove that if XM is homeomorphic to R, then X = XM . The same holds for arbitrary locally compact uncountable separable metric spaces, but is independent of ZFC if “local compactness” is omitted. Given a model of set theory, i.e. a collection ...

The Drosophila Genome: So That's What it Looks Like!

When the participants in the 41st Annual Drosophila Research Conference returned to their labs after the meeting, their working landscape had changed. The annotated sequence of the euchromatic Drosophila melanogaster genome had become public information as a result of the unprecedented collaboration between the private Celera Genomics company and the public Drosophila Genome Project consortium ...
