Chemists directly observed how hydrogen atoms behave and bond to surfaces at high temperatures using a scanning tunneling microscope. They found that dangling bonds on the surface unpaired, re-paired multiple times depending on temperature, showing favorable conditions for growing more silicon.
Researchers found a significant unmet need for treatment among urban HIV-positive women, who reported decreased sexual desire despite adequate testosterone levels. The study suggests that diagnosis and clinical attention are warranted to address this disorder.
Researchers found that patients with bereavement-related depression had decreased natural killer cell counts after disrupted sleep. The study provides direct evidence of the stress-immune relationship and highlights the importance of good sleep for maintaining health in the elderly.
Researchers at the University of Pennsylvania School of Medicine are conducting a new clinical trial combining a proven antiretroviral drug therapy with an experimental DNA vaccine to eradicate HIV. The therapy has shown promise in lowering virus levels and restoring immune system function, paving the way for a potential cure.
The Virginia Tech Center for Environmental Applications of Remote Sensing (CEARS) will provide detailed maps and spatial data to support informed development project decisions. CEARS will leverage NASA's resources and expertise to advance remote sensing research, education, and outreach.
