unblind v. Late in September 1981, the Harvard team sent its portion of the AMPIM data to the NIGH in preparation for a group meeting in Bethesda at which the participants would, for the first time, discuss unblinded results. [EnglishScienceJargon] [full cite] (May. 10, 2004)
underpowered adj. Analysis by fluorescence in situ hybridization to assess genetic amplification of Her-2-positive tumors revealed discrepancies between the two techniques used for tumor classification. Incorrect classification of a tumor’s Her-2 status could lead to underpowered statistics and erroneous results. [EnglishScienceJargon] [full cite] (Nov. 13, 2007)
user anthropologist n. He’s also sometimes referred to as a “user anthropologist.” To an outsider, the job can seem decidedly oblique. His mission, broadly defined, is to peer into the lives of other people, accumulating as much knowledge as possible about human behavior so that he can feed helpful bits of information back to the company—to the squads of designers and technologists and marketing people who may never have set foot in a Vietnamese barbershop but who would appreciate it greatly if that barber someday were to buy a Nokia.

valleytronics n. Scientists have also explored more esoteric aspects of graphene, including a prediction from more than half a century ago. Because of how the electrons flowing in graphene interact with the honeycomb chicken-wire structure, they behave as if they have no mass, always traveling at the same speed regardless of their energy, like particles of light. Dr. Beenakker at Leiden has proposed taking advantage of graphene’s unusual behavior in a new type of electronics that he calls “valleytronics.” [EnglishScience] [full cite] (Apr. 10, 2007)
wash-out effect n. In the early 1970s, manufacturers introduced sirens with different patterns and frequencies, to address a growing problem: Officers in different police cars using the same frequency often could not hear each other when approaching the same intersection, a dreaded phenomenon known as the wash-out effect that is a recipe for a crash. The yelp, the wail, the fast and the hi-lo sirens were born. [EnglishScience] [full cite] (Jun. 15, 2007)
whistler n. In other measurements, Venus Express detected the bursts of radio waves known as “whistlers,” which, at least on Earth, are generated by lightning. [EnglishScience] [full cite] (Nov. 29, 2007)
Y V Ulluq Q n. Hazy light started lingering on the southern horizon deep into the months when the sky normally would contain nothing but stars.…The sharp difference between the cold air on the ground and the warmer air above makes a prism that reflects light hundreds of kilometres away.…Mr. Davidson coined a term for the phenomenon: “Y V Ulluq Q,” combining the initials of well-known researchers in the field with the Inuit word that comes closest to describing bright twilight.

ZBLAN n. Also intriguing to space researchers is fluoride glass. A blend of zirconium, barium, lanthanum, sodium and aluminum, this type of glass (also known as “ZBLAN”) is a hundred times more transparent than silica-based glass. [EnglishScienceAcronym] [full cite] (Jun. 21, 2005)
zeitgeber n. Light and temperature are the only periodic or quasi-periodic environmental variables to which endogenous oscillation can be coupled: in nature they entrain the endogenous oscillation, thereby controlling period and establishing appropriate phase. They are, to use Aschoff’s phrase, the principal Zeitgeber. [GermanUnited StatesScienceJargon] [full cite] (Jun. 5, 2004)
zeitgeber n. No reference is made to diurnal activity, Orstreue, Zeitgeber, and other terms of the last thirty years. [ScienceJargon] [full cite] (Jun. 5, 2004)
