OpenfMRI: The growing database is helping researchers discover new insights and it could become a powerful tool for diagnosis.
Researchers around the world can compare notes on one of the most powerful tools available for imaging human brain function, the fMRI, thanks to support from the National Science Foundation (NSF). An fMRI is a functional magnetic resonance imaging scan that measures brain activity by detecting changes in blood oxygenation and flow.
The United States' (U.S.) predominance in science and technology (S&T) eroded further during the last decade, as several Asian nations - particularly China and South Korea - rapidly increased their innovation capacities. According to a report released by the National Science Board (NSB), the policy making body of the National Science Foundation (NSF) and an advisor to the President and Congress, the major Asian economies, taken together, now perform a larger share of global R&D than the U.S., and China performs nearly as much of the world's high-tech manufacturing as the U.S.
Imaging atoms is a difficult task. In fact, Berkeley Lab scientists now made the first-ever high-resolution images of a molecule as it breaks and reforms chemical bonds. Felix Fischer of the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) set out to develop nanostructures made of graphene using a new, controlled approach to chemical reactions.
The National Center for Science and Engineering Statistics (NCSES) released a report titled Doctorate Recipients from U.S. Universities: 2011 that unveils important trends in U.S. doctoral education.
President Barack Obama announced the names of 96 women and men who will receive the United States government's highest honor for scientists and engineers in the early stages of their independent research careers--the Presidential Early Career Award for Scientists and Engineers (PECASE).
Twenty Americans nominated by the National Science Foundation (NSF) are among those awardees. Together they represent a rich breadth of research disciplines which include engineering, geology, biology, economics, physics and computational science.
Self-assembling polymer materials that form three-dimensional structures like tiny wires and junctions have been prepared by researchers at MIT. They use a new self-assembly approach that is featured in this webcast. The work has the potential to usher in a new generation of microchips and other devices made up of submicroscopic features. Although similar self-assembling structures with very fine wires have been produced before, this is the first time the structures have been extended into three dimensions with different, independent configurations on different layers, the researchers say.

A curious twist in a family of plant proteins called chalcone-isomerase recently was discovered by Salk Institute for Biological Studies scientist Joseph Noel and colleagues at Iowa State University led by Eve Wurtele.
Pursuing basic scientific discovery, they found three similar proteins that could soon translate into positive results for bio-renewable fuels, commodity chemicals like plastics, food security and nutrition and biomedicine.
Inspired by nature's ability to shape a petal, and building on simple techniques used in photolithography and printing, researchers at the University of Massachusetts Amherst have developed a new tool for manufacturing three-dimensional shapes easily and cheaply, to aid advances in biomedicine, robotics and tunable micro-optics.
