Every cell has an organelle signature — a “fingerprint” created from the shape, size & arrangement of its internal structures. HHMI scientists can now read these signatures across 1000s of cells, revealing how tissues adapt to diet & disease bit.ly/4j6DmoH 📹FelicianoLab

This year’s medicine laureate Karl Deisseroth transformed the protein channelrhodopsin into a light-controlled switch for nerve cells. Deisseroth introduced the gene for channelrhodopsin into nerve cells from rats. By illuminating the cells with blue light, he was able to trigger a nerve signal. He published this breakthrough in 2005. Two years later, he made this light-controlled switch for nerve cells work in the brains of living mice. #NobelPrize

Lighting up your screen: a larval zebrafish's cellular activity. Developed by researchers at our Janelia Research Campus, WHaloCaMP is a biosensor that detects calcium signals & offers a window into how cells & organs work together. 🎥 Helen Farrants, HHMI JRC

Science moves faster when knowledge is shared openly. From the time I entered graduate school, I became fascinated by what open sharing of data could do in fields as disparate as physics, art, and coding. Total strangers helping each other go further. Sharing knowledge openly is part of the ethos of the @AllenInstitute. Every year, millions of people use our open data and tools to power their research, to learn, and even to make art. We take on foundational projects that are needed and are too big for any single lab to tackle, and build them from day one to be shared. We need to share and work together to accelerate science for a healthier world. This #OpenScienceWeek, join me in celebrating the scientists and organizations everywhere who share their data, tools, and knowledge to accelerate discovery.

Our lab was awarded a 3 year Brain Initiative R21 to develop a pipeline for predicting where to cage neuropeptides. Looking for a postdoc with expertise in docking and cell culture. (See NIH reporter link in comments for more details). Please share!
