Delving inside the cell

Looking inside the cell

Advances in imaging techniques have shed new light on the structure of vesicles formed by COPI protein complexes.

Delving into the diversity of silencing pathways

Submitted 20 March 2007; accepted 22 May 2007; published online 29 June 2007 developments include the elucidation of steps in the biogenesis of repeat-associated small interfering RNAs (rasiRNAs), new ideas about how siRNAs silence gene expression, how miRNAs repress translation, and the importance of siRNAs as tools in biological research and therapeutics. The discovery of siRNAs, which silenc...

Delving into the Whorl of Flower Segmentation

We describe an algorithm for automatically segmenting flowers in colour photographs. This is a challenging problem because of the sheer variety of flower classes, the intra-class variability, the variation within a particular flower, and the variability of imaging conditions – lighting, pose, foreshortening etc. The method couples two models – a colour model for foreground and background, and a...

Delving into the Dry - Eye Pipeline

After years of fi ts and starts, the often stalled but always prodigious machinery of the dryeye pipeline appears to be moving forward. Thanks to improvements in designing clinical trials, monitoring patients’ signs and symptoms and evaluating the performance of therapeutic agents, a number of drugs are making their way through the clinical trial process. These agents include new mucomimetics, ...
