Liqun Luo has used One to One an innovative staining technique to illuminate how a fly finds its fruit—and it’s no simple feat. Smells are first detected by olfactory receptor neurons (green) in the left and right antennal lobes of the fly brain. Then, olfactory projection neurons (blue) transmit the information to high brain centers. During construction of the olfactory circuit, 50 classes of olfactory receptor neurons and 50 classes of projection neurons must establish precise one- to-one connections (see page 32). 4000 Jones Bridge Road vol.

One might even say that scientists tend toward neophilia—defined by our friends at the Oxford English Dictionary as a love for, or great interest in, what is new. Take some of the “newest” additions to the scientific lexicon. Writing in The Scientist some years ago, the late Joshua Lederberg and linguist Alexa T. McCray sought the origins of -ome and -omics, suffixes of choice in contemporary biology. The term “genomics” may have arisen in the 1970s, but Lederberg and McCray turned to Sanskrit and Greek to understand the holistic meaning of -ome, noting that the Sanskrit syllable Om “encompasses the entire universe “The HHMI community overlaps with in its unlimitedness” and that the Greek letter omega is “the greatest other networks of researchers in this and very last character” of the alphabet, the symbolic last word. country and around the world—what So it is with some trepidation that this issue of the HHMI Bulletin introduces a graphical “interactome” that illustrates the intercon- you might describe as a human interac- nected research interests of the 56 scientists recently selected as new tome seeking to unravel the mysteries HHMI investigators (see page 20).
