Scientists are investigating the effects of stereotype threat on cognitive function, particularly in women and minority groups. The study aims to understand the physiological processes underlying these impairments and develop strategies to help affected groups cope with social stigma.
Artificial viruses are used as standards in research labs to check analysis methods, but measuring their concentration is challenging. NIST scientists now use neutrons to measure the amount of RNA in these 'fake' viruses, allowing for more accurate detection of real viruses at early stages of infection.
Researchers found that individuals with early AD who participated in a 3-to-4 month cognitive rehabilitation program showed significant improvements in face-name recognition, mental processing speeds, and time-place orientation. The study suggests that people with early AD can be taught techniques to help stay engaged in everyday life.
Changes in land use have implications for disease distribution and human health, with activities like deforestation and urban sprawl contributing to the spread of Lyme disease and malaria. The report calls for policy changes and research investments to address these issues.
A study of over 3,200 older adults found that even occasional exercise can significantly reduce the risk of death from heart disease and other causes. Physical activity was found to improve survival rates by 28-40%, depending on frequency and intensity.
The study found that a lack of universally accepted supply chain standards costs the auto industry over $5 billion annually and the electronics industry almost $3.9 billion. The lack of interoperability leads to duplicated efforts, redundant systems, and inefficient processes.
The project aims to discover how the integrated community worked, how families interacted with each other and their involvement in the Underground Railroad. The team has found artifacts consistent with the time period of New Philadelphia, including broken dinnerware, iron nails and hardware.
The number of pediatricians in the US has more than doubled since 1978, with a higher concentration in wealthier states. This disparity affects access to care among children in poorer states.
Recent advancements in microchip lasers and optics have improved LADAR systems' speed of data acquisition, range accuracy, and reliability. LADARs are now used to generate topographic images, survey large bodies of water, and document construction sites.
The NIST investigation found working hypotheses for WTC 1 and 2 collapses, key visual observations from photographic and videographic images, and insights from computer models and first-person interviews. The report also summarizes laboratory fire tests and experimental work on steel recovered from the WTC.
Researchers found that bone marrow cells can differentiate into epithelial cells under normal circumstances, suggesting a new mechanism of transformation. However, the exact mechanisms behind this process are still unclear and require further investigation.
Researchers found that black test-takers who retook the GED exam had a significant increase in pass rate, from 52% to 73%, while white test-takers saw a pass rate increase of 78% to 90%. The study suggests that allowing students to retake high-stakes exit exams can have a positive impact on low-skilled test-takers.
A study by Brown University researchers found high prevalence of life-threatening and contagious infections among incoming inmates. Nearly 20% tested positive for hepatitis B, highlighting the need for vaccination to prevent transmission upon release into the community.
A recent BioScience article highlights that decades of fire suppression may have been overly criticized, and climate has a significant impact on fire spread in high-elevation forests. The studies also reveal how invasive alien plants can dramatically alter fire regimes, proposing a scheme for evaluating the dangers of these invasions.
