The European Molecular Biology Laboratory highlights the potential for genomic research to combat tropical diseases. However, commercial interest in developing treatments has been limited, and it will be necessary to combine efforts from not-for-profit organizations and private funds to support research in developing countries.
Researchers aim to compress images for small mobile agents, reducing power requirements and enabling wireless data transmission in confined spaces. Successful technology advances could benefit search and rescue operations, soldiers' field communications, and micro-air vehicles.
A nationwide longitudinal study of psychological responses to September 11 found that six months after the attacks, effects continued throughout the country among individuals not directly affected. Those with preexisting mental or physical health difficulties and greater exposure to the attacks showed continued stress symptoms over time.
A five-year project will study the effects of rural life on children's development, focusing on competence, family factors, and community characteristics. The study will follow over 1,400 subjects from selected rural counties in North Carolina and Pennsylvania.
A new DNA typing method has been developed to help identify human remains that cannot be matched with the current protocol. The technique, called a 'miniplex,' uses a smaller set of reliable DNA markers to study tiny pieces of genetic material and could aid law enforcement in solving cases across the country.
Researchers have developed new aerogel nanocomposites that are 100 times more resistant to breakage and almost totally insensitive to moisture. The materials could be used for a variety of applications including building insulation, impact-resistant automobile bumpers and lighter aircraft frames.
Researchers found African-Americans are two to four times more likely to undergo lower limb amputations, with higher rates among above-knee amputations. The study highlights the need for further investigation into underlying causes and public health initiatives to alleviate excess risk of limb loss.
A recent study reveals that nearly 25% of adults with disabilities are obese, compared to 15% without disabling conditions. Adults with lower limb mobility difficulties face the highest risk and often lack exercise counseling from their physicians.
The Darwin Correspondence Project has published 12 of a projected 32-volume set of Darwin's letters, shedding light on his evolutionary ideas. The project is sending these volumes back to the Charles Darwin Research Station in the Galapagos, where Darwin's research began.
A five-year initiative led by Partnership for Biodiversity Informatics will enhance researchers' global access to data and information. The project aims to locate relevant data sets, utilize distributed computational services, and exercise new analysis methods.
Researchers at Cornell University discovered a previously undetected gene that regulates insect sex-pheromone production, leading to rapid evolution of chemical systems and new species emergence. The delta-14 gene allows females to change their pheromone components, attracting only one male out of 200 with the same response.
A nationwide study led by Roxane Cohen Silver found that individuals who disengaged from coping efforts after the 9-11 attacks were more likely to experience poor psychological outcomes. The study revealed that even those not directly affected by the attacks continued to experience anxiety about future terrorist attacks.
Researchers found that the quality of a male bird's learned song is linked to its attractiveness to females, who prefer well-copied wild-type songs. The study suggests that females use song-learning ability as an indicator of male quality and provides insight into the role of traits learned by males in sexual success.
Despite increased OTC sales, smoking cessation aid effectiveness has decreased, particularly among light smokers who are less responsive to these products. Researchers recommend using NRTs in combination with behavioral counseling to overcome barriers to quitting.
Researchers use satellite data to identify geographic areas at risk of terrorist threats, tracking changes in chemical and power plants, utility lines, and population density. The technology has potential for detecting airborne agents and supporting homeland security initiatives.
