Access and retrieval of the genetic information stored in DNA is a fundamental process that requires tight regulation. Research by HFSP fellow Albert Weixlbaumer of The Rockefeller University has shed light on the molecular mechanism underlying a specific type of regulation, called transcriptional pausing, revealing more information about the first step of gene expression.

A mathematical analysis of two distinct microscopic experiments, which have been thought to contradict each other, provides a quantitative description of actin turnover and recycling mechanisms at the leading edge of crawling cells.

When visual contrast changes, neurons in the retina adapt by changing their sensitivity and temporal window of stimulus integration to better match the range of incoming signals. What happens, however, when contrast only changes in some parts of a scene, for example, when a high-contrast object appears in front of a low-contrast background? By analyzing the activity of retinal neurons under spatially local changes in contrast, we found that these neurons adapt in a global fashion, adjusting how...

A device which employs musical notes is helping blind individuals to “see” using sound. This non-invasive sensory-substitution device (SSD) was named the “EyeMusic” as it converts images into a combination of musical notes or “soundscapes” that propose alternate visional guidance for visually impaired or blind people.

Understanding how the countless neurons of the central nervous system guide themselves through relatively large distances in order to find their specific synaptic targets is one of the most vital yet complex questions in neuroscience. We have used genetic and molecular manipulations at the single cell level to address how neurons in the fly connect the eye to the brain.

Short behaviours can be automatically identified from videos of crawling worms and used to discover genetic relationships between mutants. Automated methods for understanding changes in complex traits like behaviour are critical if we want to take full advantage of resources like the Million Mutation Project or large-scale gene knockout projects.

Visualizing specific DNA loci in their natural context – the cell’s nucleus – is fundamental to understanding how two meters of DNA can be packed in a space six orders of magnitude smaller. With this goal in mind, we have developed a simple but powerful quantitative method to rapidly and cost effectively engineer probes for visualizing virtually any locus in the human and mouse genome as well as entire chromosomes at high definition in single cells, using fluorescence in situ hybridization...

We combined optogenetics and new optical tools to control chemotactic behavior of Caenorhabditis elegans to understand the neural circuit that animals use to track chemo attractive gradients. We discovered that controlling the dynamics of activity in just one interneuron pair was sufficient to force the animal to locate, turn towards and track virtual light gradients.

In-vivo imaging of the dynamic behaviors of tissues and cells during organ formation in mammals has been particularly challenging, due to their in utero development. This article describes a novel, prolonged and robust live imaging system for visualizing the formation of a variety of embryonic tissues in the mid-gestation mouse embryo.

We developed a protein-protein interaction network analysis method to find the proteins which serve as links between cell cycle, cytokinesis and polarized cell growth regulation in fission yeast cells and experimentally verified the method on one of the predicted proteins.
