A new study found that combat veterans are more likely to be heavy smokers and drinkers, while also experiencing lower physical inactivity compared to non-veterans. The research suggests that combat exposure may exert long-term adverse effects on cardiovascular risks.
The photoelectric effect, first explained by Einstein in 1905, has become a crucial tool for understanding the properties of matter. The new issue of New Journal of Physics features research on hot electrons and high-temperature superconductors, demonstrating its relevance to tailored electronic materials.
A study found that exposure to traffic emissions at menarche (first menstrual period) and first birth was associated with increased breast cancer risk in premenopausal and postmenopausal women, respectively. The findings support the hypothesis that early-life exposures contribute to breast cancer risk.
PNNL's ecological dock design reduces harm to nearshore marine life, while a new system tracks juvenile salmon behavior, aiding restoration of critical habitats. The lab also developed a cost-effective nanomaterial to remove mercury from industrial wastes, significantly reducing production costs.
A new study confirms the Earth's energy is out of balance, with more energy absorbed from the sun than emitted back to space. The imbalance, measured at 0.85 watts per meter squared, will cause an additional 0.6 degrees Celsius warming by the end of this century.
Dr. Chen will use his Guggenheim Fellowship to research the structures and properties of ferroelectric and multiferroic thin films with potential applications in various functional devices. He aims to develop theories and multiscale computational models for predicting their behaviors.
A study suggests non-surgical alternatives to facelifts can improve the neck and chin area, reducing the appearance of a 'wattle'. These procedures use liposuction and muscle tightening techniques, with moderate to marked improvement seen in over two-thirds of treated patients.
Research finds that prenatal cocaine exposure is associated with smaller head circumference at birth and less optimal home environments, leading to mild effects on developmental outcomes. These effects persist into childhood, particularly as children face increased demands in the formal school years.
Researchers at ASU have developed a novel method to detect DNA mutations using nanocrystals that can recognize subtle changes in DNA. This technology has the potential to diagnose genetic diseases, detect infectious agents, and provide reliable forensic analysis.
The NCR network tested its disease surveillance system, ESSENCE, in a simulated bioterrorist attack to identify areas for improvement and enhancement. The exercise showcased the system's effectiveness in providing early warning alerts to public health officials.
Researchers from WHOI studied salt fingers in the tropical Atlantic, injecting a tracer into the ocean and measuring its spread nine months later. The results showed enhanced mixing of salt and heat, with salt fingers playing a crucial role in shaping the ocean's temperature and salinity structure.
