NSF-funded researchers have developed a new algorithm that can be used to reveal the genetic ancestry of thousands of individuals in minutes. The new software looks for specific DNA markers known as single nucleotide polymorphisms, or SNPs (pronounced snips), and needs nothing more than a DNA sample in the form of a simple cheek swab.
A study of the sediments associated with the mass extinction event that led to the demise of the earth's dinosaur population and the crater formed when a massive asteroid collided with the earth show that the two events are separated by as much as 300,000 years. The findings cast doubt on the popular theory that the asteroid collision caused the extinction of dinosaurs.
This fact sheet, summarizing remarks by NSF Director Arden L. Bement, Jr., describes how NSF intends to implement the American Recovery and Reinvestment Act (ARRA), which included a 50 percent boost in 2009 funding for the agency. ARRA funds were used to support the nation's best researchers and to fund new instrumentation programs.
In a speech to the National Academies of Science, President Obama announced a collaboration between NSF and the U.S. Department of Energy (DOE) that addresses the need to "spark a sense of wonder and excitement" in the nation's youth and encourage the pursuit of careers in science and engineering. This fact sheet includes information about the President's plan to develop new energy technologies.
In June, NSF announced the launch of Science Nation, a series of video reports produced by NSF that examine breakthroughs and the possibilities for new discoveries about ourselves, our planet and our universe. Jeff Nesbit, director of NSF's Office of Legislative and Public Affairs, said, "We are pleased to be able to educate and engage the American public about the diverse range of NSF-funded cutting-edge research that is going on every day."
Experts say that Haiti's recent earthquake was anything but a "natural" disaster. While the root cause was a geological event, a magnitude 7.0 earthquake, this natural occurrence would not have produced the near-catastrophic results it has, according to several NSF-funded researchers, were it not for Haiti's enormous social and economic problems, including a lack of modern building standards and practices.
NSF supports a wide variety of research into the causes and management of disasters, including several that focus on the social aspects of these tragic events. The Natural Hazards Center, located at the University of Colorado–Boulder, is funded by a consortium of federal agencies including NSF. The Center administers a "Quick Response Grant Program" to rapidly collect data during and after earthquakes.
NSF has also supported the Earthquake Engineering Research Institute (ERRI) to deploy fast reconnaissance teams whenever a significant earthquake happens anywhere in the world. The teams gather relevant data and draw lessons that might be applied to safer building and infrastructure construction. EERI has already assembled a research group to study the Haiti earthquake; as we were going to press, the team had already begun to arrive in Haiti. Other NSF-funded teams have also deployed to the area to assess the possibilities for future quakes. Information gathered from past disasters is available from EERI's NSF-funded "Learning from Earthquakes" project, available here.
These and other NSF-sponsored research projects have revealed that social vulnerabilities are key to understanding how serious a natural disaster will be and can also provide guidance to those seeking to rebuild after a disaster. Susan Cutter, director of South Carolina's Hazards and Vulnerability Research Institute, partially funded by NSF, maps out social vulnerabilities to disaster across the United States. Her work shows that it is the vulnerability of a population as much as the severity of the natural event that determines how catastrophic a disaster will really be. Cutter has provided expert testimony to Congress on hazards and vulnerabilities and served on a team that investigated the societal impacts on the severity of the Katrina disaster.
A Virginia Tech professor has developed novel software that promises to increase the efficiency of computers. According to Kirk Cameron, his MiserWare application has helped some users save as much as 35 percent on energy costs. The software is an intelligent power management system that automatically balances the energy demands on a computer system by adjusting power consumption when the system is not being heavily used. The software is available for both Linux and Widows-based computers. NSF supported the development of MiserWare through its Small Business Innovation Research grants program. Cameron has also been supported by other NSF funding for his research on high-power, high-efficiency computing.
The 2010 issue of Science and Engineering Indicators was released on January 15 and is available to the public here. The report, prepared biennially by the National Science Board and delivered to the President and Congress in even-numbered years, tracks the progress of the country by measuring a variety of statistics related to the research and development (R&D) enterprise. Among the data included in the 2010 report are those showing annual R&D growth in the U.S. lagging behind that of several Asian countries, including South Korea and Japan. While the U.S. continues to lead the world in scientific publications, other countries are catching up. China, for example, now produces 8 percent of the world's research publications, up from just 2 percent of the world's share in 1995.
Katharine Flores is bringing the highly technical methods of materials science to bear on a problem of great interest to sports enthusiasts: the strength of the protective helmet worn by bicyclists, hockey players and other athletes. If these helmets shatter or fail to absorb the impact of a blow to the head, serious injury or even death can result.
Flores' NSF-funded research in the Department of Materials Science and Engineering at Ohio State University (OSU) is focused on the development of a class of materials known as bulk metallic glasses, or BMGs, that are ideal for use in applications ranging from surgical tools to protective sports equipment. The materials have attractive properties for these applications, including extraordinary tensile strength and the ability to undergo large deformations upon impact without fracturing. BMGs are a type of metallic alloy that don't crystallize when cooled below their melting point but, rather, settle into a liquid-like disordered structure. Although the resulting materials are, technically, a type of glass, they can be formed into shapes the way plastics are molded but produce a finished product with the hardness and strength of a metal.
The BMG materials that Flores is currently studying are composed largely of zirconium combined with smaller amounts of copper, nickel, aluminum and other metals. Small samples of these alloys are studied in Flores' lab using a variety of highly sophisticated techniques to investigate the molecular events that occur when the materials are deformed by impact or pressure. Flores believes that it is a lack of understanding of these materials at the molecular level that limits more general application of them in society, and that further uses will be discovered when the materials are more thoroughly understood. Read more about her research here.
Prior to joining the faculty at OSU, Flores was the director of the Sports Materials Laboratory at Stanford University where she established an industry-funded research program on the development of materials for sports application. In addition to her research and teaching duties at OSU, Flores serves as the director of education and outreach for NSF's Center for Emergent Materials.
More recently, Flores has expanded her outreach and education activities by participating in a joint project between NSF and NBC News. Just in time for the winter games, scheduled for February, 2010, the NSF/NBC partnership has produced a 16-part video series on "The Science of the Winter Olympics" that will be broadcast during the games. View the NSF Special Report to read more about this partnership and to watch Flores and other scientists explain the science behind the winter games.

Use of Brain-Controlled Devices Not Science Fiction (CNN) The hit movie "Avatar" features a paraplegic soldier using brain signals to control sophisticated equipment. Research supported by NSF shows that this science-fiction scenario is quickly becoming reality.
Discovery of Water on Planet Orbiting Nearby Star (The New York Times) Astronomers reported the discovery of water on a planet orbiting a nearby red-dwarf star. The planet has an atmosphere of superheated steam and other gases. The work, supported by NSF, was the subject of an NSF Webcast.
On May 10, 1950, President Harry S. Truman signed a bill establishing the National Science Foundation. The President announced the creation of the new federal agency, dedicated to advancing the scientific enterprise of the United States, from the rear platform of a train in Pocatello, Idaho. Alan T. Waterman, chief scientist at the Office of Naval Research, was nominated by President Truman as NSF's first director and provided with a budget of $225,000. From that initial allocation, the National Science Board, established along with NSF and given oversight over its operations, made 97 grants, including one to physical chemist Max Delbruck, who went on to win the 1969 Nobel Prize in Medicine. Additional historical details are available here.
Three productions, made possible with partial financial support from NSF, have been recognized as winners of the 2009 AAAS Kavli Science Journalism Award. The awards, first given in 1945, are the first to be endowed by the Kavli Foundation, an independent organization dedicated to advancing science for the benefit of humanity. Winners of this year's awards will be recognized at the 2010 AAAS annual meeting.
