The Ensembl (http://www.ensembl.org/) database project provides a bioinformatics framework to organize biology around the sequences of large genomes. ...
With a total of nine genome sequences available from Ensembl and more genomes to follow, recent developments have focused mainly on closer integration between genomes and external data. ...
The Ensembl project is funded principally by the Wellcome Trust with additional funding from EMBL and NIH-NIAID. ...

We show that the canonical ensemble in any of the six supersymmetric string theories, type IIA and IIB, type IB and type I', or heterotic E_8 x E_8 and Spin(32)/Z_2, exhibits a strong version of holography ...
We show that, in the presence of Dbranes, and a consequent Yang-Mills gauge sector, the thermal ensemble of type II strings is infrared stable, with neither tachyons nor massless scalar tadpoles. ...
The thermodynamics of an ensemble of strings is not the same as that of an ensemble of infinitely many free particle species with Planck scale masses. ...
