Brain-imaging studies reveal that voting decisions are more associated with the brain's response to negative aspects of a politician's appearance than to positive ones, says a team of researchers from the California Institute of Technology (Caltech), Scripps College, Princeton University, and the University of Iowa. This appears to be particularly true when voters have little or no information about a politician aside from their physical appearance.

Join two world-renowned California Institute of Technology (Caltech) physicists and an award-winning composer for the world premiere of "Einstein's Cosmic Messengers," an inventive multimedia concert. Inspired by Caltech's involvement with the Laser Interferometer Gravitational-wave Observatory (LIGO), the presentation takes an innovative approach to communicating scientific exploration and discovery to the general public. The event takes place Thursday, October 30, at 8 p.m., in Beckman Auditorium on the Caltech campus.

An international team of scientists has discovered microscopic, magnetic fossils resembling spears and spindles, unlike anything previously seen, among sediment layers deposited during an ancient global-warming event along the Atlantic coastal plain of the United States.

Engineers from the California Institute of Technology (Caltech) have created a "plug-and-play" synthetic RNA device--a sort of eminently customizable biological computer--that is capable of taking in and responding to more than one biological or environmental signal at a time.

The transportation of antibodies from a mother to her newborn child is vital for the development of that child's nascent immune system. Those antibodies, donated by transfer across the placenta before birth or via breast milk after birth, help shape a baby's response to foreign pathogens and may influence the later occurrence of autoimmune diseases. Images from biologists at the California Institute of Technology (Caltech) have revealed for the first time the complicated process by which these antibodies are shuttled from mother's milk, through her baby's gut, and into the bloodstream, and offer new insight into the mammalian immune system.

Genetically modifying a receptor found on the neurons that produce the neurotransmitter dopamine has given California Institute of Technology (Caltech) researchers a unique glimpse into the workings of the brain's dopamine system--as well as a new target for treating diseases that result from either too much or too little of this critical neurotransmitter.

Astronomers at the California Institute of Technology (Caltech) and their colleagues have provided unique insight into the nature of a young star-forming galaxy as it appeared only two billion years after the Big Bang and determined how the galaxy may eventually evolve to become a system like our own Milky Way.

How a cell achieves the coordinated control of a number of genes at the same time, a process that's necessary for it to regulate its own behavior and development, has long puzzled scientists. Michael Elowitz, an assistant professor of biology and applied physics at the California Institute of Technology (Caltech), along with Long Cai, a postdoctoral research scholar at Caltech, and graduate student Chiraj Dalal, have discovered a surprising answer. Just as human engineers control devices ranging from dimmer switches to retrorockets using pulsed--or frequency modulated (FM)--signals, cells tune the expression of groups of genes using discrete bursts of activation.

An explanation for a strange property of noctilucent clouds--thin, wispy clouds hovering at the edge of space at 85 km altitude--has been proposed by an experimental plasma physicist at the California Institute of Technology (Caltech), possibly laying to rest a decades-long mystery.

The advantage of using two eyes to see the world around us has long been associated solely with our capacity to see in three dimensions. Now, a new study by scientists at Rensselaer Polytechnic Institute in New York and the California Institute of Technology (Caltech) has uncovered a truly eye-opening advantage to binocular vision: the ability to see through things.
