An optimized optogenetic clustering tool for probing protein interaction and function

The Arabidopsis photoreceptor ​cryptochrome 2 (​CRY2) was previously used as an optogenetic module, allowing spatiotemporal control of cellular processes with light. Here we report the development of a new ​CRY2-derived optogenetic module, ‘​CRY2olig’, which induces rapid, robust, and reversible protein oligomerization in response to light. 89 more words

Changing a Negative Feeling About a Memory

This is exciting, but complicated, basic research. Here I simplify the main experiments. Neuroscientists at the Massachusetts Institute of Technology (MIT) have identified a neuronal circuit in mice that associates a positive or negative feeling with a memory. 812 more words

Science wants to help you forget about it!

Before I explain, I urge you to reread that title in a comical Italian-American voice.

Two research teams have discovered the phenomenon of reconsolidation, the process of rewiring or wholly erasing emotional connections with specific memories. 301 more words
