The optogenetic toolset is composed of genetically encoded molecules that, when targeted to specific neurons in the brain, enable the electrical activity of those neurons to be driven or silenced by light. When these opsins are expressed in the lipid

Take a tour of the Linac Coherent Light Source (LCLS), whose ultra-powerful X-ray beam is being used to solve the structures of proteins that are notoriously hard to crystallize.
This animation illustrates optogenetics—a radical new technology for controlling brain activity with light. Ed Boyden, the co-inventor of this technology, is a professor at the MIT Media Lab and at the McGovern Institute for Brain Research, where he continues to develop new technologies for controlling brain activity.
A powerful new X-ray–generating laser is imaging smaller crystals than ever before.
University College London researcher Mike Taylor recounts the discovery of a new dinosaur with unusually powerful thigh muscles. Read the full story.
Columbia University evolutionary ecologist Dustin Rubenstein explains just why it's so interesting and important to find slime molds that engage in a form of agriculture.
The volvocine algae are a model system for studying the evolution of multicellularity, as the group contains extant species ranging from the unicellular Chlamydomonas to a variety of colonial species and the full-fledged multicellular Volvox varietie
