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

Robert Tindol
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

Marcus Woo

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.

Memory Lane in the Brain

Biologist Erin Schuman is interested in how memories are formed--or forgotten. The landscape the professor of biology at the California Institute of Technology explores is the hippocampus, the part of the brain known to be crucial for memory in humans and other animals.

Caltech Bioinformatics Experts DevelopNew Literature Search Engine for Biologists

Robert Tindol
When it comes to finding a used book on the Internet, one merely needs to Google the title, and a few suitable items for sale will soon be just a click away. But for the biologist or medical researcher looking for information on how two nematode genes interrelate in hopes of better understanding human disease, there is a clear need for a more focused search engine.

Research uncovers new facts about odor detection in insects; findings could lead to more effective repellents

Robert Tindol
If you think it doesn't do much good to swipe the fly that's going after the potato salad, guess again. You may be discouraging the fly's colleagues from taking up the raid.

Caltech Professor Awarded Stein and Moore Award for Insights Into the Life Cycle of Cells

Ubiquitin is a small protein that has a very big job. Or jobs, to be more accurate. Indeed, the ubiquitin system is central to--literally--just about everything significant that goes on inside cells, and to a lot of intercellular business as well. Once unknown and, until the 1980s, unheralded, the ubiquitin system is now one of the major areas of study in cell biology, biochemistry, and genetics, and the point of convergence for many disparate disciplines.

New Class of Reagents Developed by Caltech Chemical Biologists for In Vivo Protein Tracking

Robert Tindol
One of the big problems in biology is keeping track of the proteins a cell makes, without having to kill the cell. Now, researchers from the California Institute of Technology have developed a general approach that measures protein production in living cells.
