The only constant in life, it's said, is change. To further our understanding of how humans cause, respond and adapt to change, NSF has awarded 26 grants through its Human and Social Dynamics (HSD) investment area. HSD aims to foster breakthroughs in understanding the dynamics of human action and development, as well as knowledge about organizational, cultural and societal adaptation and change. This year's HSD awards cover topics ranging from the diffusion and transmission of knowledge and ideas, to natural resource use and its impacts on human societies, to the neural interactions underlying human behavior.
Examples of HSD award topics include: the environmental impacts of shipping pallets, cell phone batteries and water delivery systems; computer-based decision support systems to respond to natural disasters; modeling community response and economic impacts of risk following a terrorist strike; modeling interactions between individual behavior networks and public policy to support public health epidemiology, and evaluating the social, economic and political aspects of U.S. ethanol policy. See NSF's press release for a complete list of award topics.

In Biology 101, we all learned that babies inherit two copies of their genes--one from their mother and one from their father. With most genes, these two copies are both expressed in the child. For some mammalian genes, however, only one parent's copy is active, regardless of the child’s gender. Through a process called imprinting, molecular signals "silence" the copy of the gene the child inherits from the other parent, leaving the child with only one working copy of the gene. If this only functioning copy is damaged or lost, there's no backup copy to rely on, leaving the child vulnerable to disease.
Scientists have now created the first map of human imprinted genes, revealing four times as many imprinted genes as had been previously identified. Many of the 156 newly-identified imprinted genes lie within genomic regions linked to major diseases. Researchers say that some of these genes may offer clues to better disease prevention or management.
The team validated two particularly interesting genes on chromosome 8, where none had been found before. One of those genes, KCNK9, is known to cause cancer and may also be linked to bipolar disorder and epilepsy. The second, DLGAP2, is a possible bladder cancer tumor suppressor gene.

The malaria parasite has been studied for decades, but surprisingly, little is known about how it behaves in humans to cause disease. An international research team supported by NSF has for the first time measured which of the malaria parasite's genes are turned on or off during actual infection in humans, not in cell cultures, unearthing surprising behaviors and opening a window on the most critical aspects of parasite biology.
That insight springs from the genomic analysis of parasites in their natural state, derived directly from patients residing in Senegal, and also from the researchers' use of innovative computational approaches to interpret their results. These computational methods helped to identify three distinct biological states of the malaria parasite: an active growth-based state, a starvation response and an environmental stress response, presumably related to the body's inflammatory response to the parasite. This physiological diversity was previously unknown and may help explain the widely varying course of the disease in different patients, from mild, flu-like illness to coma and even death.

The complexities of modern manufacturing present a daunting challenge to companies focused on maximizing the bottom line without compromising customer satisfaction. Software firm Invistics addresses industry's need to function at peak efficiency by producing software and services packages incorporating the principles of "lean" manufacturing, which involve the analysis, prediction and optimization of manufacturing and supply chain processes. A number of Fortune 500 companies have adopted Invistics' software products to slash production times and achieve on-time deliveries. The recipient of four NSF Small Business Innovation Research (SBIR) grants since 2001, Invistics now employs 25 and generates significant annual revenues. In 2007, it received the prestigious Tibbetts Award, given to a select group of outstanding SBIR recipients each year. The award is named for Roland Tibbetts, who began the SBIR program in 1977 as an experimental project at NSF.

The Internet traces its origins to an NSF-funded computational network created to support and promote networking in education and research in the United States. Established in the early 1980's and using the same "TCP/IP" protocol as the military's restricted ARPANET, "NSFNET" grew quickly as people realized the benefits of open access networking. In 1987, NSF awarded a grant to IBM, MCI and a center at the University of Michigan to create a network of networks, or inter-net, and the Internet we know today was born.

Methicillin-resistant Staphylococcus aureus (MRSA) causes "staph" infections that are resistant to treatment with the usual antibiotics. According to data from the Centers for Disease Control and Prevention (CDC), approximately 43% of all hospital-reported staph infections are related to MRSA. The recent media frenzy surrounding localized outbreaks of this potentially deadly infection throughout the nation has highlighted the need for increased research in the field of bacteriology.
The Small Grants for Exploratory Research (SGER) program is one mechanism NSF uses to support fundamental science and engineering projects whose results may enable our country to better mitigate, prepare for, respond to and recover from catastrophic events, such as disease outbreaks.
One recently funded SGER study, led by Professor Lisa Plano at the University of Miami, is evaluating a possible connection between the microbial density of S. aureus and symptoms of infection reported in beachgoers, as well as the possibility of person-to-person transmission through ocean water. Plano's research will focus on the recreational marine waters along the coast of South Florida.
The real-life implications of this study reach well beyond the waters of southern Florida. Establishing a link would provide a method for risk analysis in the presence of this bacteria. New health and hygiene recommendations, established using results from this study, may help to prevent infection at crowded beaches or, at the very least, better inform the public of the risk they assume when they spend an afternoon at the beach.
