Invited for the cover of this issue are the groups of Yanhua Lan, PeterW. Roesky, and Stefan Bräse at the Karlsruhe Institute of Technology, and Ignacio Fernández at the University of Almeri´a. The image depicts seals on a North Sea beach. Seals are known to be very skilled at balancing and other tricks, whereas our skills include crystallizing new compounds and further examining their properties.

Electron tomography allows structural studies of cellular structures at molecular detail. Large 3D reconstructions are needed to meet the resolution requirements. The processing time to compute these large volumes may be considerable and so, high performance computing techniques have been used traditionally. This work presents a vector approach to tomographic reconstruction that relies on the exploitation of the SIMD extensions available in modern processors in combination to other single processor optimization techniques. This approach succeeds in producing full resolution tomograms with an important reduction in processing time, as evaluated with the most common reconstruction algorithms, namely WBP and SIRT. The main advantage stems from the fact that this approach is to be run on standard computers without the need of specialized hardware, which facilitates the development, use and management of programs. Future trends in processor design open excellent opportunities for vector processing with processors SIMD extensions in the field of 3D electron microscopy.
