Lecture or listen: When patients waver on meds According to a new analysis of hundreds of recorded office visits, doctors and nurse practitioners typically issued orders and asked closed or leading questions when talking to their HIV-positive patients about adherence to antiretroviral therapy. Attempts at problem-solving with patients who had lapsed occurred in less than […]

In lab, Pannexin1 restores tight binding of cells lost in cancer Ties that bind/ Cancerous rat cells (black) expressing the protein Pannexin1 are bound within a strong network of actin (red), while adjacent cells that don’t express Pannexin1 (green) have much less developed actin network around them. (Click image for higher resolution.) / Credit: Brian Bao/Brown University By studying tumor cell […]

Biochip measures glucose in saliva, not blood Engineers at Brown University have designed a biological device that can measure glucose concentrations in human saliva. The technique could eliminate the need for diabetics to draw blood to check their glucose levels. The biochip uses plasmonic interferometers and could be used to measure a range of biological […]

Many high-risk Americans don’t get hepatitis B vaccine A recently published study investigating hepatitis B vaccination rates in the United States found that more than half of adults at risk for hepatitis B virus remain unvaccinated. With many of these individuals making contact with the healthcare system, including HIV testing, this statistic reflects many missed […]

Gym benefits help Medicare plans recruit healthy seniors Medicare Advantage plans are not allowed to exclude unhealthy (and costly) seniors, but new research in the New England Journal of Medicine shows that they have effectively used gym memberships to bring healthier (and more profitable) members into their subscriber base. PROVIDENCE, R.I. [Brown University] — Because healthy enrollees cost […]

Cosmetic chemical hinders brain development in tadpoles A new study finds that low concentrations of the chemical methylisothiazolinone has subtle but measurable negative effects on the neural development of tadpoles. The chemical is found in some cosmetics, although the study does not provide any evidence that cosmetics are unsafe for humans. Interrupted development/Even small concentrations […]

Altered gene tracks RNA editing in neurons RNA editing is a key step in gene expression. Scientists at Brown University report in Nature Methods that they have engineered a gene capable of visually displaying the activity of the key enzyme ADAR in living fruit flies. Fluorescing flies/ Fruit flies treated with a gene that glows green in the […]

Researchers find best routes to self-assembling 3-D shapes Researchers at Brown and Johns Hopkins universities have found optimal configurations for creating 3-D geometric shapes — like tiny, highly simplified geodesic domes that assemble by themselves. The Brown team developed the algorithmic tools, and the Johns Hopkins team tested selected configurations. The research may lead to […]
