BELLINGHAM, Washington, USA -- Wearable visualization systems (WVS) are at the forefront of consumer electronics product development, and social media companies are investing heavily in enabling compelling experiences through augmented and virtual reality (AR/VR). A special section on Wearable Vision Systems: Head/Helmet-Mounted Displays in this month's issue of Optical Engineering, published by SPIE, the international society for optics and photonics, aims to help boost consumer-driven advances in applications in automotive, industrial, and military vision systems. "Significant commercial investment in WVS for personal communications and entertainment is driving rapid advances in miniature optoelectronics components and product design," note special section guest editors Darrel Hopper (U.S. Air Force Research Lab), James Melzer (Thales Visionix, Inc.), Michael Browne (SA Photonics), and Peter Marasco (U.S. Air Force Research Lab). Their goal with the special section is to facilitate consumer-driven advancements in the design of specialty applications including automotive, industrial, and military vision systems. The editorial lists key challenges, including achieving performance in a near-to-eye (NTE) visualization system sufficient to compel users to tolerate shortcomings including latency, acuity, field-of-view, fashion, and donning and doffing. VR immerses viewers in an artificial environment richly characterized by ultrahigh-definition graphics, while AR involves imagery superimposed over the real world that can be perceived in real time. Accurate tracking of position, head, and eye is needed for some VR and all AR applications. Papers in the section describe a variety of approaches and technologies. In "Daylight luminance requirements for full-color, see-through, helmet-mounted display systems," Thomas Harding and Clarence Rash (U.S. Army Aeromedical Research Lab and Oak Ridge Institute for Science and Education) describe two lines of investigation in luminance requirements to address visual perception issues of concern when color is implemented in eyes-out, see-through helmet-mounted displays. "Review of head-worn displays for the next-generation air transportation system" by Jarvis (Trey) Arthur et al. (NASA Langley Research Center), summarizes the results of NASA's 30-plus years of helmet-mounted and head-worn displays. The study tracks progress in wearable collimated optics, head tracking, latency, and weight reduction, as well as safety, operational, and cost benefits. A "Review of conformal displays: more than a highway in the sky" by Niklas Peinecke et al., German Aerospace Center, surveys more than 40 years of research in synthetically generated symbols such as routing information, navigation aids, specialized landing displays, obstacle warnings, drift indicators, and others. The study also looks ahead, outlining research trends for the years to come. Other papers in the special section include: Michael Eismann, Chief Scientist, Sensors Directorate, U.S. Air Force Research Lab, Wright-Patterson Air Force Base, is editor-in-chief of Optical Engineering. The journal is published in print and digitally by SPIE in the SPIE Digital Library, which contains more than 458,000 articles from SPIE journals, proceedings, and books, with approximately 18,000 new research papers added each year. Abstracts are freely searchable, and a number of journal articles are published with open access. SPIE is the international society for optics and photonics, an educational not-for-profit organization founded in 1955 to advance light-based science, engineering, and technology. The Society serves nearly 264,000 constituents from approximately 166 countries, offering conferences and their published proceedings, continuing education, books, journals, and the SPIE Digital Library.

Nationwide, counties with the poorest quality across five domains - air, water, land, the built environment and sociodemographic - had the highest incidence of cancer, according to a new study published in the journal Cancer. Poor air quality and factors of the built environment -- such as the presence of major highways and the availability of public transit and housing - - were the most strongly associated with high cancer rates, while water quality and land pollution had no measurable effect. The findings may help reduce cancer by driving policy to lower pollution in areas with high cancer rates linked to the environment. Previous research has shown that genetics can be blamed for only about half of all cancers, suggesting that exposure to environmental toxins or socioeconomic factors may also play a role. "Most research has focused on single environmental factors like air pollution or toxins in water," said Jyotsna Jagai, research assistant professor of environmental and occupational health in the University of Illinois at Chicago School of Public Health and lead author of the study. "But these single factors don't paint a comprehensive picture of what a person is exposed to in their environment -- and may not be as helpful in predicting cancer risk, which is impacted by multiple factors including the air you breathe, the water you drink, the neighborhood you live in, and your exposure to myriad toxins, chemicals and pollutants." To investigate the effects of overall environmental quality, the researchers looked at hundreds of variables, including air and water pollution, pesticide and radon levels, neighborhood safety, access to health services and healthy food, presence of heavily-trafficked highways and roads, and sociodemographic factors, such as poverty. Jagai and her colleagues used the U.S. EPA's Environmental Quality Index, a county-level measure incorporating more than 200 of these environmental variables and obtained cancer incidence rates from the National Cancer Institute's Surveillance, Epidemiology, and End Results Program State Cancer Profiles. Cancer data were available for 85 percent of the 3,142 U.S. counties. The average age-adjusted rate for all types of cancer was 451 cases per 100,000 people. Counties with poor environmental quality had higher incidence of cancer--on average, 39 more cases per 100,000 people--than counties with high environmental quality. Increased rates were seen for both males and females, and prostate and breast cancer demonstrated the strongest association with poor environmental quality. The researchers found that high levels of air pollution, poor quality in the built environment and high levels of sociodemographic risk factors were most strongly associated with increased cancer rates in men and women. The strongest associations were seen in urban areas, especially for the air and built environment domains. Breast and prostate cancer were most strongly associated with poor air quality. "Some of the counties we looked at were very large, with both urban and rural areas in a single county, so to tease apart the interplay between the measures of quality in our five domains and how they impact urban and rural areas," Jagai said, "we will need to look at geographic areas smaller than counties." Co-authors on the study are Lynne Messer of Portland State University; Kristen Rappazzo and Danelle Lobdell of the U.S. Environmental Protection Agency; and Chris Gray and Shannon Grabich of the University of North Carolina, Chapel Hill and the Oak Ridge Institute for Science and Education. This research was funded in part by contracts EP09D000003 and EP12D000264 from the EPA Office of Research and Development and by an appointment to the Internship/Research Participation Program Office of Research and Development (National Health and Environmental Effects Research Laboratory) of the EPA, administered by the Oak Ridge Institute for Science and Education through an interagency agreement between the EPA and the Department of Energy.

Anne White has always relished challenges. As an undergraduate, she was fascinated by fluid dynamics, and the prospect of nuclear fusion as a game-changing energy source. She followed those passions to her current position as the Cecil and Ida Green Associate Professor of Nuclear Science and Engineering, where she spends much of her time studying plasma turbulence — which is a challenge unto itself. “I like it because it’s really difficult,” she says. “You take fluid turbulence and add electrical and magnetic fields, which make it even harder to understand. Then you heat it to 100 million degrees and have to figure out ways to measure it and see what it’s doing. That’s why I’m at home here at MIT — everyone’s really excited about tough things.” But plasma turbulence isn’t just an intellectual exercise for MIT’s Department of Nuclear Science and Engineering. It’s also a key obstacle in the worldwide effort to realize fusion’s potential as a clean, economical source of electricity, fueled by safe and readily available materials. Achieving that potential requires the reliable creation and harnessing of “burning plasmas” — ongoing reactions in a charged, superheated gas that create more energy than they consume, the same process that powers stars. “We’ve been able to achieve the plasma densities and temperatures we need, but haven’t been able to keep the plasma dense enough and hot enough for a long enough time to achieve a burning state,” notes White. The problem is turbulence, which saps heat from the plasma and stops the fusion of atomic nuclei. White’s team, working at MIT’s Plasma Science and Fusion Center (PSFC) and in intensive collaboration with other groups worldwide, is an international leader in assessing and refining the mathematical models used in fusion reactor design. “We compare turbulence transport models with experimental data, validating them so there can be confidence in their predictive ability,” she says. This work has led to a new perspective on the nature of plasma turbulence, a discovery that has changed the standard model used to understand conditions inside fusion reactors. “We’ve always known that there’s big turbulence, on scale of an ion Larmor radius [the radius of the helical path of a charged particle in a magnetic field], and much smaller turbulence, on the scale of an electron Larmor radius, and that each can be dominant at different times,” explains White. “You’d expect electron turbulence to be dominant in more extreme plasma conditions. But all indications are that it’s dominant even in simple vanilla plasma processes, which was unexpected.” That discovery (which involved doctoral student Choongki Sung, undergraduate Curran Oi, and collaborating scientists from the Oak Ridge Institute for Science and Education, the University of California at San Diego, and General Atomics) is now backed up by new cutting-edge simulation results. The project is informing research across the fusion community, and represents the type of collaborative development that will be a model for the PSFC going forward. Much international attention is currently focused on the International Thermonuclear Experimental Reactor (ITER), currently being built in France. The facility, one of the biggest scientific projects in history, will be a milestone, but White says subsequent generations of reactors must quicken the pace. “There’s great confidence that when ITER is built, it will [achieve burning plasma], we know the development path,” says White. “The trouble is that the existing path is so big and expensive, and the time step between iterative experiments is so long, that advancement gets stifled.” One promising avenue is smaller, more nimble projects, like MIT’s proposed Affordable, Robust, Compact reactor design, which is being explored at PSFC under newly appointed director Dennis Whyte. “This type of smaller, more modular reactor is a way of leaping ahead and evaluating advances in materials science, magnet technology, and other fields,” says White, who notes that the trend will make reliable plasma transport models even more important. White, who recently received the School of Engineering’s Junior Bose Award for teaching as well as several national honors for her research, maintains an active class schedule — graduate plasma physics, an undergraduate electronics class and the popular 22.012 (Seminar in Fusion and Plasma Physics), which attracts undergrads from across the Institute and other local universities. “They’re really excited about fusion and energy,” says White, who hopes to bring more students (including undergraduates) into her group’s efforts. While acknowledging that the path to practical fusion will be long and expensive, White takes heart from the fact that with ITER, “countries representing more than half the world’s population are working on a $20 billion science project. On balance, isn’t it amazing that all these countries are teaming up to do something for the good of the world? The science will be awesome, but science for peace is a really strong thing.”

Background: Recent large clinical trials have found that pre-exposure prophylaxis (PrEP) reduced HIV infection among men who have sex with men (MSM), but efforts to provide clinical care to minors, including young MSM, may be complicated by a lack of clarity regarding parental consent requirements with respect to medical services. Purpose: The goal of this paper was to analyze law related to a minor's ability to consent to medical care, including HIV diagnostic testing and treatment, and its implications for PrEP. Methods: Analysis was performed in 2012 on laws current as of December 31, 2011. Public Health Law Program staff collected all statutes and regulations pertaining to an adolescent's ability to consent to HIV diagnostic testing and treatment and sexually transmitted infection (STI) diagnostic testing, treatment, and prevention. Results: No state expressly prohibits minors' access to PrEP or other HIV prevention methods. All jurisdictions expressly allow some minors to consent to medical care for the diagnosis or treatment of STIs, but only eight jurisdictions allow consent to preventive or prophylactic services. Thirty-four states either expressly allow minors to consent to HIV services or allow consent to STI or communicable disease services and classify HIV as an STI or communicable disease. Seventeen jurisdictions allow minors to consent to STI testing and treatment, but they do not have an express HIV provision nor classify HIV as an STI or communicable disease. Conclusions: Minors' access to PrEP without parental consent is unclear, and further analysis is needed to evaluate how state law may relate to the provision of clinical interventions for the prevention of HIV infection. © 2013 American Journal of Preventive Medicine.

The ability of carbon nanotubes (CNTs) to undergo surface modification allows them to form nanocomposites (NCs) with materials such as polymers, metal nanoparticles, biomolecules, and metal oxides. The biocidal nature, protein fouling resistance, and fouling release properties of CNT-NCs render them the perfect material for biofouling prevention. At the same time, the cytotoxicity of CNT-NCs can be reduced before applying them as substrates to promote biofilm formation in environmental biotechnology applications. This paper reviews the potential prospects of CNT-NCs to accomplish two widely varying objectives in environmental engineering applications: (i) preventing biofouling, and (ii) promoting the formation of desirable biofilms on materials surface. This paper addresses practical issues such as costs, risks to human health, and ecological impacts that are associated with the application, development and commercialization of CNT-NC technology. © 2010 Elsevier Inc.

There is a great necessity for development of novel sensory concepts supportive of smart sensing capabilities in defense and homeland security applications for detection of chemical and biological threat agents. A smart sensor is a detection device that can exhibit important features such as speed, sensitivity, selectivity, portability, and more importantly, simplicity in identifying a target analyte. Emerging nanomaterial based sensors, particularly those developed by utilizing functionalized gold nanoparticles (GNPs) as a sensing component potentially offer many desirable features needed for threat agent detection. The sensitiveness of physical properties expressed by GNPs, e.g. color, surface plasmon resonance, electrical conductivity and binding affinity are significantly enhanced when they are subjected to functionalization with an appropriate metal, organic or biomolecular functional groups. This sensitive nature of functionalized GNPs can be potentially exploited in the design of threat agent detection devices with smart sensing capabilities. In the presence of a target analyte (i.e., a chemical or biological threat agent) a change proportional to concentration of the analyte is observed, which can be measured either by colorimetric, fluorimetric, electrochemical or spectroscopic means. This article provides a review of how functionally modified gold colloids are applied in the detection of a broad range of threat agents, including radioactive substances, explosive compounds, chemical warfare agents, biotoxins, and biothreat pathogens through any of the four sensory means mentioned previously. © 2011 Elsevier B.V.
