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.

The California Institute of Technology has successfully completed a $111 million fundraising effort begun in 1998 to expand the biological sciences. The $111 million exceeds the original $100 million goal.
Funds raised during the Biological Sciences Initiative (BSI) will make possible a new building on the Pasadena campus, new professorships and fellowships, new faculty appointments, and a wide range of new research programs.

If you stare at a bright red disk for a time and then glance away,
you'll soon see a green disk of the same size appear and then
disappear. The perceived disk is known as an afterimage, and has
long been thought to be an effect of the "bleaching" of
photochemical pigments or adaptation of neurons in the retina and
merely a part of the ocular machinery that makes vision possible.

David C. Chan, an assistant professor of biology at the California Institute of Technology, has been named a Rita Allen Foundation Scholar. The award carries a $50,000 stipend for up to three years.
Chan specializes in research on mitochondria, components of the cell important in energy metabolism and also in programmed cell death. Specifically, he investigates the manner in which cells coordinate mitochondrial functions with the development of tissues and organs.

Computer "organisms" challenge conventional Darwinian thinking

Biologists have long known the advantages of sexual reproduction to the evolution and survival of species. With a little sex, a fledgling creature is more likely to pass on the good mutations it may have, and more able to deal with the sort of environmental adversity that would send its asexual neighbors floundering into the shallow end of the gene pool.

For us living creatures with backbones, existence begins as a single fertilized cell that then subdivides and grows into a fetus with many, many cells. But the details of how those cells end up as discrete organs instead of undifferentiated heaps of cells is only now being understood in microscopic detail.
Why, for example, should some of the cells migrate to the region that will become the brain, while others travel netherward to make a spinal cord?

Pamela Bjorkman, professor of and executive officer for biology at the California Institute of Technology, is one of 72 American scientists elected this year to membership in the National Academy of Sciences (NAS). The announcement was made earlier this month in Washington at the 138th annual meeting of the academy.
