...issue of Nature, activates fluorescent proteins in neurons. The colors then combine to produce an array of more than 100 different shades. The new approach was discovered by a team led by Jeff W. Lichtman and Joshua R. Sanes, both professors in the Department of Molecular and Cellular Biology who teach MCB 80, “Neurobiology of Behavior,” in the spring. “Brainbow provides a way of seeing many neurons at the same time in the same place,” said Lichtman, who coined the name for the technique. “With...

...work in a significant way, he wouldn’t attach his name to it,” Berg said of Watson. “In that regard, he’s very ethical.” Robert A. Lue, the executive director of undergraduate education in molecular and cellular biology at Harvard, called for Watson to speak out further. “A lot depends on what Jim Watson does next,” Lue said. “This is an opportunity for him to address the issue directly. One could imagine not just an apology...
...body, insulin helps convert food into cellular energy. But the brain has other uses for insulin, namely as a means to learn and make new memories. Here's how it works: At synapses, the spaces across which brain cells communicate and where memories are conceived, neurons reserve special parking spots just for insulin. When the hormone pulls in, a connection is made that enables new memories to form. Since new memory formation is one of the first things to go awry in people with early stages of the disease, this insulin-initiated process may hold the key to decoding...
...understand that the function of insulin at those synapses is to modulate and influence the underlying cellular structure of memories," says William Klein, professor of neurobiology and physiology at Northwestern University and a co-author of the study published online by the FASEB Journal. "What we have here is a striking phenomenon that may ultimately explain why the brains of people with Alzheimer's disease are insulin resistant and how that ties into memory...
