PASADENA, Calif. — The American Philosophical Society (APS) recently announced that Pamela J. Bjorkman, professor of biology at Caltech and investigator of the Howard Hughes Medical Institute (HHMI), and Peter B. Dervan, Bren Professor of Chemistry, are two of the 37 new members elected in this year.
Bjorkman is being recognized for her work with molecules needed for cell-surface recognition, and their role in the immune system.

As a young medical student, Matthew Porteus recalls his frustration when admitting his first patient with chronic pain caused by sickle-cell anemia. There was little medicine could do to help her in a sustained and meaningful way. The experience influenced his decision to study the basic mechanisms of "gene targeting," one possible way to cure such diseases, which are caused by a single mutation in a cell. Now Porteus will be assisted in his studies thanks to a grant from the Burroughs Wellcome Fund.

Most natural smells are complex blends of many individual chemicals. Freshly ground coffee, for example, contains about 300 individual volatile components. A typical perfume also contains tens of ingredients, although the recipes are tightly locked in secret vaults.
The percepts that such complex blends evoke in us are, however, astonishingly singular: ground coffee smells like coffee, not like a hopeless mess of hundreds of ingredients; Gio or Allure also have unique signatures (often associated with other memories).

Scientists at the California Institute of Technology and Purdue
University have determined the fine-detail structure of the virus
that causes dengue fever. This advance could lead to newer and more
focused strategies for devising a vaccine to protect the world
against a viral illness that causes 20,000 deaths each year.
Reporting in the March 8 issue of the journal Cell, Caltech
biology professor James H. Strauss, lead author Richard J. Kuhn of
Purdue (a former postdoctoral scholar in Strauss's lab), and
Michael G. Rossman and Timothy S. Baker, both of Purdue, describe

Using specially prepared HIV-derived viruses stripped of their disease-causing potential, California Institute of Technology biologist David Baltimore and his team have invented a new method of introducing foreign DNA into animals that could have wide-ranging applications in biotechnology and experimental biology.
The Baltimore team reports, on today's Science Express Web site, on their study of single-cell mouse embryos that have been virally infected in a manner that leaves a new gene from a jellyfish permanently deposited into their genomes.

Scientists at the California Institute of Technology have discovered that hearing can significantly change visual perception, and that the influence of hearing on visual perception occurs at an early perceptual level rather than at a higher cognitive level.
Ladan Shams, a Caltech postdoctoral researcher, and Shinsuke Shimojo, a professor of computation and neural systems at Caltech report that visual signals are influenced significantly by sounds at early cortical levels that have been believed to be "vision specific."

Caltech biology professor Barbara Wold has been appointed director of the Beckman Institute, President David Baltimore announced today. She succeeds founding director Harry Gray, who will return to full-time professorial duties after 15 years at the institute's helm.
Wold, who specializes in embryonic development and regeneration in vertebrates, will lead the Beckman Institute in its continuing goal of building a research interface between chemistry and biology, Baltimore said.
