Stunning images of Andromeda demonstrate the world’s most powerful astronomical camera

Stunning images of the Andromeda Galaxy are among the first to emerge from a new wide-field camera installed on the enormous Subaru Telescope atop the Hawaiian mountain Mauna Kea. The camera, called the Hyper-Suprime Cam (HSC), is the result of an international collaboration between Princeton University astrophysicists and Japanese and Taiwanese scientists.

With this new camera, researchers will be able to conduct a “cosmic census” of hundreds of millions of galaxies in a wide swath of sky in sufficient depth to probe mysteries such as dark matter and dark energy, while searching for baby galaxies in the early universe. The images of the Andromeda Galaxy demonstrate the new camera’s ability to capture images for a large-scale survey that will help scientists understand the evolutionary history and fate of the expanding universe. The camera’s enormous field of view allowed the entire Andromeda Galaxy, which is some 60,000 light years across, to be captured in a single shot. (more…)

Changes in language and word use reflect our shifting values, UCLA psychologist reports

Study analyzes more than 1 million books published over 200 years

A new UCLA analysis of words used in more than 1.5 million American and British books published between 1800 and 2000 shows how our cultural values have changed.

The increase or decrease in the use of certain words over the past two centuries — a period marked by growing urbanization, greater reliance on technology and the widespread availability of formal education — reveals how human psychology has evolved in response to major historical shifts, said Patricia Greenfield, a distinguished professor of psychology at UCLA and the author of the study.

The value of seeing a mind in meditation

Using neurofeedback techniques, Dr. Judson Brewer of Yale says he can teach people to “see” the subjective experience known to meditators as mindfulness. Brewer explains that too often we trip ourselves up when we get caught up in our own thinking. In the video and accompanying research papers, Brewer and colleagues describe how subjects can […]

A new high-tech analysis led by a University of Colorado Boulder researcher shows the oldest known petroglyphs in North America, which are cut into several boulders in western Nevada, date to at least 10,500 years ago and perhaps even as far back as 14,800 years ago. (more…)

Researchers Find New Way to Create ‘Gradients’ for Understanding Molecular Interactions

Scientists use tools called gradients to understand how molecules interact in biological systems. Researchers from North Carolina State University have developed a new technique for creating biomolecular gradients that is both simpler than existing techniques and that creates additional surface characteristics that allow scientists to monitor other aspects of molecular behavior.

A gradient is a material that has a specific molecule on its surface, with the concentration of the molecule sloping from a high concentration on one end to a low concentration at the other end. The gradient is used not only to determine whether other molecules interact with the molecules on the gradient, but to determine the threshold level at which any interactions take place. (more…)
