A nanophenomenon that triggers the bone-repair process
Researchers have resolved one of the great unknowns in bone self-repair: how the cells responsible for forming new bone tissue are called into action. Their work reveals the role of an electromechanical phenomenon at the nanoscale, flexoelectricity, as a possible mechanism for stimulating the cell response and guiding it throughout the fracture repair process.

Infant mortality rates in Texas vary dramatically from one zip code to the next
Infant mortality rates in Texas vary dramatically even across neighboring zip codes, according to a new analysis and mapping tool. The analysis and searchable map, which are the first of their kind in Texas, use data from Texas Vital Statistics Linked Birth and Death Records from 2011-2014.

Cystic fibrosis bacterial burden begins during first years of life
Cystic fibrosis shortens life by making the lungs prone to repeated bacterial infections and inflammation. Researchers have now shown for the first time that the lungs' bacterial population changes in the first few years of life as respiratory infections and inflammation set in. This research offers a way to predict the onset of lung disease in children with CF and suggests a larger role for preventive therapies, such as hypertonic saline.

Creation of synthetic horsepox virus could lead to more effective smallpox vaccine
Researchers created a new synthetic virus that could lead to the development of a more effective vaccine against smallpox. The discovery demonstrates how techniques based on the use of synthetic DNA can be used to advance public health measures.

'Explosive evolution' of techniques to restore blood flow to the brain
Recent decades have seen an 'explosive evolution' of techniques to restore blood flow to areas of the brain endangered by stroke or clogged arteries, according to a new report.

Researchers illustrate how muscle growth inhibitor is activated, could aid in treating ALS
Researchers have identified how the inactive or latent form of GDF8, a signaling protein also known as myostatin responsible for limiting muscle, is activated.

Hedgehog signaling proteins keep cancer stem cells alive
Scientists have discovered that the survival of cancer stem cells is dependent on the 'Hedgehog signaling pathway'. Targeting this pathway had previously shown no effect on the growth of colorectal cancer. Now, scientists have demonstrated that using different drugs to target a specific aspect of the pathway may yield better treatment outcomes for patients.

Factor that doubles the risk of death from breast cancer identified
Researchers have discovered that the risk of death from breast cancer is twice as high for patients with high heterogeneity of the estrogen receptor within the same tumor as compared to patients with low heterogeneity. The study shows that the higher risk of death is independent of other known tumor markers and also holds true for Luminal A breast cancer.

Increasing number of adolescents receive a psychiatric or neurodevelopmental diagnosis
According to a national register study comparing Finnish birth cohorts from 1987 and 1997, an increasing number of adolescents receive a psychiatric or neurodevelopmental diagnosis. The number of diagnosed adolescents increased especially for girls in the younger cohort.
