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.

Four from Caltech Named to National Academy of Sciences

Three members at the California Institute of Technology faculty and one former faculty who is now a visiting associate are among the 72 new members and 18 foreign associates being named to the National Academy of Sciences today. The election was announced during the 142nd annual meeting of the Academy in Washington, D.C.

Five from Caltech Faculty Elected to American Academy of Arts and Sciences

Five faculty members at the California Institute of Technology are among this year's newly elected fellows of the American Academy of Arts and Sciences. They join 191 other Americans and 17 foreign honorees as the 225th class of fellows of the prestigious institution that was cofounded in 1780 by John Adams.

HHMI Investigator's Approach Could Lead to Novel Drug Design, New Way to Generate Energy

For anyone suffering from cystic fibrosis or AIDS, the bacterium Pseudomonas aeruginosa is bad news. While the organism is found everywhere--including in sediment on the ocean floor--it can cause lung infections in those with weak immune systems.

McKnight Awards Go to Two from Caltech

Richard Andersen, Boswell Professor of Neuroscience, and Kai Zinn, professor of biology, both of the California Institute of Technology, have each received a 2005 McKnight Neuroscience of Brain Disorder Award.

Toward a Longer, Healthier Life

In two separate awards from the Ellison Medical Foundation, two scientists from the California Institute of Technology are taking a much more scholarly approach to the ravages of aging. Harry Gray, a chemist, has been awarded $970,000 to reveal the structure of a protein and a peptide that underlie two age-related diseases, Alzheimer's and Parkinson's, while biologist Alexander Varshavsky has been awarded $972,000 to conduct a systematic investigation of the genetics and biochemistry of aging.

Scientists Discover What You Are Thinking

By decoding signals coming from neurons, scientists at the California Institute of Technology have confirmed that an area of the brain known as the ventrolateral prefrontal cortex (vPF) is involved in the planning stages of movement, that instantaneous flicker of time when we contemplate moving a hand or other limb.

Potential New Approach to Fighting Cancer

Although the immune system handles most of these disease-causing organisms and insults well, it does a poor job of suppressing the growth of tumors.

Caltech computer scientists embed computation in a DNA crystal to create microscopic patterns

In a demonstration that holds promise for future advances in nanotechnology, California Institute of Technology computer scientists have succeeded in building a DNA crystal that computes as it grows. As the computation proceeds, it creates a triangular fractal pattern in the DNA crystal.

A "Smoking Gun" For Nicotine Addiction

Nicotine is responsible for more than four million smoking-related deaths each year. Yet people still smoke. Why? One reason is the stranglehold of addiction, started when nicotine enhances the release of a neurotransmitter called dopamine, a chemical messenger that induces a feeling of pleasure. That's what smoking, presumably, is all about.
