Deciphering the Mystery of Bee Flight

One of the most elusive questions in science has finally been answered: How do bees fly?

Modified Mice Test Alzheimer's Disease Drugs

Alzheimer's disease is a progressive brain disorder that afflicts an estimated 4.5 million Americans and that is characterized by the presence of dense clumps of a small peptide called amyloid-beta in the spaces between neurons.

Caltech Researchers Join Global GEM4 Initiative

Researchers at the California Institute of Technology have joined a global medical effort to address a number of diseases through innovative, multi-institutional, multidisciplinary approaches. The initiative, the Global Enterprise for Micromechanics and Molecular Medicine (GEM4), is centered at MIT's Department of Materials Science and Engineering, and was officially launched October 12 at an MIT campus ceremony.

Baltimore to Retire as Caltech President; Will Remain at Institute as Biology Professor

David Baltimore, the seventh president of the California Institute of Technology, will retire on June 30, 2006, after nearly nine years in the post. He will remain at the Institute, where he intends to focus on his scientific work and teaching.

Caltech Stem Cell Biology Training Program Awarded $2.3 Million

At a historic meeting today in Sacramento, a three-year, $2.3 million grant was earmarked for the creation of the Caltech Stem-Cell Training Program at the California Institute of Technology.

Authority on the Brains and Behavior of Owls and Songbirds Wins Neuroscience Prize

Masakazu "Mark" Konishi, a California Institute of Technology neuroscientist renowned for his work on the neural wiring that allows owls to swoop in on their prey in darkness and songbirds to sing, and his former postdoctoral researcher Eric Knudsen, who is now chair of the neurobiology department at Stanford University, have been awarded this year's Peter Gruber Foundation Neuroscience Prize.

Baltimore Offered $13.9 Million from Grand Challenges in Global Health Initiative for AIDS Research

The Grand Challenges in Global Health initiative, a major effort to achieve scientific breakthroughs against diseases that kill millions of people each year in the world's poorest countries, today offered 43 grants totaling $436.6 million for a broad range of innovative research projects involving scientists in 33 countries, including David Baltimore, president of the California Institute of Technology. The ultimate goal of the initiative is to create "deliverable technologies"--health tools that are not only effective, but also inexpensive to produce, easy to distribute, and simple to use in developing countries.

Single-Cell Recognition: A Halle Berry Brain Cell

Now a research team of neuroscientists from the California Institute of Technology and UCLA has found that a single neuron can recognize people, landmarks, and objects--even letter strings of names ("H-A-L-L-E-B-E-R-R-Y"). The findings, reported in the current issue of the journal Nature, suggest that a consistent, sparse, and explicit code may play a role in transforming complex visual representations into long-term and more abstract memories.

Norman Horowitz Dies; Conducted Experiment with Viking Lander to Search for Life on Mars

Norman Horowitz, a geneticist best known for his work on the "one-gene, one-enzyme" hypothesis and the experiments aboard the Viking lander to search for life on Mars in 1976, died on Wednesday, June 1, at his home in Pasadena. He was 90.

Caltech Neuroscientists Unlock Secrets of How the Brain Is Wired for Sex

Reporting in the May 19 issue of the journal Neuron, David Anderson, Caltech's Roger W. Sperry Professor of Biology and a Howard Hughes Medical Institute investigator, his graduate student Gloria Choi, and their colleagues describe their discovery that the neural pathway between the amygdala and hypothalamus thought to govern reproductive behaviors is marked by a gene with the rather unromantic name of Lhx6.
