New global report launched by the International AIDS Society recommends a new paradigm for treating injecting drug users: 'Seek, test, treat and retain'

The International AIDS Society launches a new report recommending a science-based approach to scaling up treatment and prevention of HIV amongst Injecting Drug Users (IDUs). The 'Seek, test, treat and retain' model advocates for expanding outreach, testing, treatment, and retention services within the criminal justice system.

Premature death less likely than end stage renal disease for African-Americans with kidney disease

African Americans with hypertensive nephrosclerosis have a higher rate of developing end stage renal disease (ESRD) than dying prematurely, according to a new study. The study analyzed data from the African American Study of Kidney Disease and Hypertension (AASK) trial and cohort phase, finding that ESRD rates exceeded mortality rates ...

Could diabetes be in your bones?

Two new studies reveal a key molecular link between bone remodeling and metabolism, finding that osteocalcin levels are tied to insulin resistance and glucose intolerance. Osteocalcin treatment improves symptoms in mice with diabetes-like conditions.

Math model of colon inflammation singles out dangerous immune cells

Researchers at Virginia Tech have created a mathematical model of colon inflammation that identifies pro-inflammatory macrophages as key culprits for unregulated inflammation in inflammatory bowel disease. The model allows scientists to explore cellular and molecular changes underlying chronic inflammation, identify intervention points...

Women, but not men, who are exposed to radiation therapy as children much more prone to stillbirths or baby death when attempting to have children

A new study published in The Lancet found that women who underwent radiation therapy as children are more likely to experience stillbirths or baby deaths when attempting to conceive. In contrast, no increased risk was found for men exposed to similar levels of radiation. The authors suggest that uterine damage may be the primary factor...

Researchers find genetic link to children's emotional problems precipitated by bullying

Researchers have discovered a genetic variation that moderates whether victims of bullying develop emotional problems. The study, published in the Journal of the American Academy of Child and Adolescent Psychiatry, found that a specific gene variant affects the severity of emotional distress in bullied children.

Penn collaboration leads to simpler method for building varieties of nanocrystal superlattices

A team of chemists, physicists and materials scientists at the University of Pennsylvania created a new method to rapidly grow centimeter-scale membranes of binary nanocrystal superlattices by crystallizing a mixture of nanocrystals on a liquid surface. The study demonstrates a new way to control nanocrystal size, shape and concentration.

Brain scans may help guide career choice

Researchers used MRI scans to investigate the neurological basis for performance on vocational guidance tests, finding that gray matter correlates differ between broad and narrow test types. This study provides a basis for investigating whether brain scans can provide unique information for vocational choice.

Idaho STEM gets million dollar boost

The University of Idaho is launching a new STEM Educational Research Initiative, supported by a four-year, $1.2 million funding from the Micron Technology Foundation. The initiative aims to identify and address root causes of why Idaho students may not perform well in STEM fields and develop programs to overcome those barriers.

Lack of insurance coverage remains obstacle to wider colorectal cancer screening with CT colonography

A recent study found that a significant number of patients are willing to undergo computed tomography colonography (CTC) for colorectal cancer screening, but are hesitant to pay out-of-pocket fees. The study suggests that CTC availability could improve screening rates if insurance coverage were more widely available.

Research links recreational pool disinfectants to health problems

A recent study by University of Illinois researchers found that the application of disinfectants in recreational pools can lead to adverse health outcomes. The study suggests that brominating agents should be avoided as disinfectants, and that a combination of UV treatment with chlorine is the best method to treat pool waters.

Data mining made faster

A University of Utah computer scientist has devised a new method to simplify and speed up data mining, allowing for the analysis of high-dimensional data. The new approach can handle larger datasets than previous methods, making it useful for various applications in natural and social sciences.

Black hole jerked around twice

Astronomers discovered a giant black hole with its spin axis pointing in a different direction after two collisions with smaller galaxies. The observations suggest that the black hole was jerked around twice, creating cavities and radio jets.

Nitric oxide does not prevent poor lung development or increase survival of preterm infants overall, but black babies did better than non-black

A randomized controlled trial found that nitric oxide treatment did not improve overall survival or reduce poor lung development in preterm infants. However, black babies showed a higher survival rate compared to non-black babies. The study suggests that ethnic origin may affect the response to nitric oxide treatment.

High-resolution imaging expands vision research of live birds of prey

Researchers have developed a non-invasive imaging tool to study the retina of live birds of prey, producing detailed images for the first time in history. The new spectral-domain optical coherence tomography (SD-OCT) system shows unprecedented three-dimensional information about the retina's layers and structure.
