George Mason researchers led the largest study to date examining the relationship between the two conditions, with findings suggesting that endometriosis may have health implications beyond the reproductive system.

Every year, more than 120,000 newborns worldwide contract HIV, a global health burden that requires lifelong treatment for millions of people — assuming they have access and can afford it. New research led by Oregon Health & Science University suggests another possibility: a one-time regimen of therapies given to newborns within three days of birth to permanently clear the virus.

Researchers used image-based spatial transcriptomics, a technology that maps gene expression in a tissue with subcellular resolution, to characterize acute rejection and response to immunomodulatory therapies following heart transplantation. The study, reported Aug. 10 in Nature Cardiovascular Research, linked cell-specific gene expression patterns to the development of cardiac allograft vasculopathy, a form of chronic rejection that limits long-term survival.

Women live longer than men in nearly every country in the world, yet they experience higher rates of disability, dementia and many other age-related conditions. Scientists have long noted these differences, but they still do not fully understand why they occur — or how that knowledge can be used to improve healthy aging. A new $7.5 million, five-year grant from the National Institutes of Health will establish the USC Geroscience Specialized Center of Research Excellence on Sex Differences in Aging (GeroSCORE) to address that challenge.

Biologists show how the prefrontal cortex, a brain region associated with learning more flexible behaviors, can sometimes block the ability of a mouse to adopt a better way to solve a problem.
