The dream of saving and sharing functional magnetic resonance imaging (fMRI) data is quickly becoming a reality, according to Dartmouth researchers who run the fMRI Data Center, which archives and distributes the raw data from studies that track brain activity using fMRI. The Dartmouth researchers wrote an essay in the May issue of Nature Neuroscience about the initial reluctance and gradual acceptance of the center, and they describe the many attributes a center such as theirs offers the scientific community.
"The fMRI Data Center was created with sharing information in mind," says John Van Horn, the lead author on the paper and a Research Associate Professor of Psychological and Brain Sciences. "We wanted to advance and expand the cognitive neuroscience field by making the raw data accessible to more people for free."
According to the essay, the faculty who created the fMRI Data Center in 2000 were met with initial resistance from fellow neuroscientists. Some researchers were hesitant to give away their data; some questioned whether new science could arise from old data; and others thought that the technical hurdles could not be overcome. Despite these concerns, the Dartmouth group went ahead and teamed up with the Journal of Cognitive Neuroscience and made it a requirement to include raw fMRI data when submitting research to the publication. With initial support from the National Science Foundation, the W.M. Keck Foundation and the National Institute of Mental Health, the computer equipment was purchased and fMRI Data Center was established.

Scientists develop first tool to use machine learning methods to compute flow around interactively designable 3D objects. Tool will be presented at this year’s prestigious SIGGRAPH conference.
When engineers or designers want to test the aerodynamic properties of the newly designed shape of a car, airplane, or other object, they would normally model...
Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.
Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....
Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
Scientists have discovered that the electrical resistance of a copper-oxide compound depends on the magnetic field in a very unusual way -- a finding that could help direct the search for materials that can perfectly conduct electricity at room temperatur

The quality of materials often depends on the manufacturing process. In casting and welding, for example, the rate at which melts solidify and the resulting microstructure of the alloy is important. With metallic foams as well, it depends on exactly how the foaming process takes place. To understand these processes fully requires fast sensing capability. The fastest 3D tomographic images to date have now been achieved at the BESSY II X-ray source operated by the Helmholtz-Zentrum Berlin.
Dr. Francisco Garcia-Moreno and his team have designed a turntable that rotates ultra-stably about its axis at a constant rotational speed. This really depends...
