McDonnell Foundation Grant Will Be Used to Study Neurons Involved in Snap Decisions

Jill Perry
Where do you get your "gut feelings," that intuition that leads you to distrust someone who appears trustworthy? It could be your Von Economo brain cells in action, and a neurobiologist at the California Institute of Technology intends to find out for sure.

Researchers Determine How Plants Decide Where to Position Their Leaves and Flowers

Robert Tindol
One of the quests of modern biologists is to understand how cells talk to each other in order to determine where to form major organs. An international team of biologists has solved a part of this puzzle by combining state-of-the-art imaging and mathematical modeling to reveal how plants go about positioning their leaves and flowers.

Neuroscientists Discover the Neurons That Act As Novelty Detectors in the Human Brain

Robert Tindol
By studying epileptic patients awaiting brain surgery, neuroscientists for the first time have located single neurons that are involved in recognizing whether a stimulus is new or old. The discovery demonstrates that the human brain not only has neurons for processing new information never seen before, but also neurons to recognize old information that has been seen just once.

Caltech Scientists Discover the Part of the Brain That Causes Some People to Be Lousy in Math

Robert Tindol
Most everyone knows that the term "dyslexia" refers to people who can't keep words and letters straight. A rarer term is "dyscalculia," which describes someone who is virtually unable to deal with numbers, much less do complicated math.

Caltech Scientists Gain Fundamental Insight into How Cells Protect Genetic Blueprints

Robert Tindol
Molecular biologists have known for some time that there is a so-called checkpoint control mechanism that keeps our cells from dividing until they have copied all the DNA in their genetic code. Similar mechanisms prevent cells from dividing with damaged DNA, which forms, for example, in one's skin after a sunburn. Without such genetic fidelity mechanisms, cells would divide with missing or defective genes.

Researchers Create New "Matchmaking Service" Computer System to Study Gene Interactions

Robert Tindol
Biologists in recent years have identified every individual gene in the genomes of several organisms. While this has been quite an accomplishment in itself, the further goal of figuring out how these genes interact is truly daunting.

Old-World Primates Evolved Color Vision to Better See Each Other Blush, Study Reveals

Robert Tindol
Your emotions can easily be read by others when you blush—at least by others familiar with your skin color. What's more, the blood rushing out of your face when you're terrified is just as telling. And when it comes to our evolutionary cousins the chimpanzees, they not only can see color changes in each other's faces, but in each other's rumps as well.

Caltech Launches Brain Study Program with $8.9 Million Gift from Eli Broad to Fund 24 Researchers and Six New Labs

For years, scientists have worked to study each of the 100 billion neurons in the human brain. But while they understand individual neurons, they've been stumped by how neurons work together, how they encode information, and how they generate thoughts, emotions, and actions.

Baltimore Is President-Elect of the American Association for the Advancement of Science

Robert Tindol
David Baltimore, president of the California Institute of Technology since 1997, has been chosen to serve as president-elect of the American Association for the Advancement of Science. Baltimore will begin his term as president-elect on February 21, at the close of the 2006 annual AAAS meeting, and will begin his one-year term as president in February 2007.
