A recent study found that 78% of HIV-positive N.C. men and women prisoners had unprotected sex with their main partner in the year before imprisonment. Upon release, 26% admitted to having sex without condoms with that same person within a day or two.
Scientists discovered a freshening trend in the Labrador Sea and found that mixing of warm and cool waters may prevent El Nino. Additionally, researchers speculated about the cause of high Arctic ozone loss and suggested Martian methane could be an indicator of subsurface life.
A new study published in Personality and Social Psychology Bulletin finds that children who exhibit narcissistic tendencies are more aggressive after experiencing social rejection. The researchers suggest that reducing instances of social rejection and promoting positive self-images could help prevent violence in schools.
The University of Michigan College of Engineering will unveil the Fast Imaging Plasma Spectrometer (FIPS), a revolutionary instrument for NASA's MESSENGER Mission to Mercury. The FIPS project demonstrates how high-performance, low-weight instruments can be used to explore the solar system without risk to human life.
Researchers have detected layers of high-level moisture and cirrus clouds using NCAR's instrument package, indicating a significant impact on long-term climate. These clouds, often missed by standard weather balloons and sensors, can warm the planet and trap radiation.
A meta-analysis of randomized clinical trials found that pacemaker therapy reduced death from progressive heart failure by 51% and hospitalizations by 29%. The device range in cost $20,000 to $50,000 and improves quality of life for heart failure patients.
The study found that boosting GW433908 with ritonavir reduced the incidence of PI-resistance selected by either the study PI or NRTIs ABC and 3TC. In contrast, unboosted 908 had a higher rate of resistance to 3TC and some patients developed mutations associated with APV resistance.
Most prematurely born children show significant improvements in cognitive abilities, such as verbal comprehension and intelligence tests, between ages 3 and 8. Environmental factors like increasing age, maternal education, and absence of brain injury are linked to higher scores.
A long-term study of 54,412 women found that those who cared for loved ones for nine hours or more per week had a higher risk of coronary heart disease. The researchers suggest that mental distress, financial burdens, and limited social support may contribute to this increased risk.
Researchers have discovered a genetic signature, known as the IFN expression signature, associated with severe lupus symptoms. This signature is linked to interferon activity and has implications for developing new therapies to block IFN pathways in patients with severe lupus.
The Johns Hopkins Bloomberg School of Public Health has been awarded $30 million to develop and introduce a pneumococcal vaccine for children in the world's poorest countries. The Pneumococcal Accelerated Development and Introduction Plan (ADIP) team will work with international partners to address research, supply, and financing issue...
Study reveals floodplains have significantly higher diversity of native and exotic plants due to flooding, which washes away existing plants and transports seeds. This creates opportunities for invasive species to establish themselves, posing a threat to native plant populations.
