GAL4 system in Drosophila: a fly geneticist's Swiss army knife.

Today, the cell phone is the dominant mobile device. What comes next? As circuit density improves, we see a convergence of mobile device functionality&151;cell phones combined with PDAs or with email capability or both. Where do we go from here?

Ten years after its first beta version, Microsoft's SharePoint is now gathering momentum in organisations around the world. Herve Basset reviews what this means for information professionals

Transglutaminase 2 (TG2) is the most widely distributed member of the transglutaminase family with almost all cell types in the body expressing TG2 to varying extents. In addition to being widely expressed, TG2 is an extremely versatile protein…

Spectraplakins are multifunctional proteins that interact with all three types of cytoskeletal filaments. In this issue, Wu et al. (2008) demonstrate a new actin-dependent ATPase activity for the spectraplakin ACF7 that allows it to guide…

This article describes a general discrete-signal network that appears, in various forms, inside many digital signal processing (DSP) applications. So the "DSP Tip" for this column is for every DSP engineer to become acquainted with this network. We…

Central to the pathogenesis of many bacterial pathogens is the ability to deliver effector proteins directly into the cells of their eukaryotic host. EspF is one of many effector proteins exclusive to the attaching and effacing pathogen family that…

Plant peroxidases (class III peroxidases) are present in all land plants. They are members of a large multigenic family. Probably due to this high number of isoforms, and to a very heterogeneous regulation of their expression, plant peroxidases are…

Bioluminescence is a process during which light in the visible spectrum is emitted as a consequence of an enzymatic reaction catalyzed by luciferases. Luciferases have been identified mainly in marine organisms and are used for several biological…

For organic chemists, the construction of CC bonds is the most essential aspect of the assembly of molecules. Transition-metal-catalyzed coupling reactions have evolved as one of the key tools for this task. Lately, gold has also emerged as a…

This paper will examine how DTrace, a kernel- based dynamic scriptable tracer, can be effectively used for reverse engineering tasks. DTrace offers an unprecedented view of both user and kernel space, which has many interesting implications for…
