An analysis of 15 years of US Department of Transportation statistics found that airline consolidation has had little negative impact on on-time performance.

Dentists in good compliance with American Heart Association guidelines, according to Rochester epidemiology project

EurekAlert! - Lun, 05/22/2017 - 22:00
In the first study examining dental records in the Rochester Epidemiology Project, results show that dentists and oral surgeons are in good compliance with guidelines issued by the American Heart Association (AHA) in 2007, describing prophylactic antibiotic use prior to invasive dental procedures.

Family history of Alzheimer's may alter metabolic gene that increases risk for disease

EurekAlert! - Lun, 05/22/2017 - 22:00
A new Iowa State University study may have identified the link that explains years of conflicting research over a mitochondrial gene and the risk for Alzheimer's disease. Researchers found a dramatic difference in the gene's impact on memory, general cognitive function and risk based on a family history of Alzheimer's disease and the length of a specific section of the gene.

US child welfare system could save $12 billion, improve outcomes

EurekAlert! - Lun, 05/22/2017 - 22:00
Improving prevention and treatment services are realistic reforms to the child welfare system that could improve long-term outcomes for children while cutting $12 billion in costs. RAND developed a quantitative model to reach its recommendations. The model is the first-ever attempt to integrate risk of maltreatment, detection, paths through the system and consequences to predict the impact of policy changes.

Just one alcoholic drink a day increases breast cancer risk, exercise lowers risk

EurekAlert! - Lun, 05/22/2017 - 22:00
A new report that analyzed the global scientific research on how diet, weight and exercise affect breast cancer risk finds there are steps women can take to lower their risk. The report finds that daily alcohol consumption and adult weight gain increase risk; physical activity and breastfeeding lower risk. The report also reveals, for the first time, that vigorous exercise decreases the risk of both pre- and post-menopausal breast cancers.

Pediatricians can play a pivotal role in reducing pediatric firearm-related injuries

EurekAlert! - Lun, 05/22/2017 - 22:00
A review led by Children's National Health System researchers published May 23, 2017 in Hospital Pediatrics indicates that while firearms are present in 18 percent to 64 percent of US homes, almost 40 percent of parents erroneously believe that their children are unaware where weapons are stored, and 22 percent of parents wrongly think that their children have never handled household firearms.

Light-sensitive E. coli paint a colourful picture

Nature News - Lun, 05/22/2017 - 12:12

Microbes have been genetically engineered to sense red, green and blue light, and to produce pictures of what they 'see'.

Total synthesis of flueggenine C via an accelerated intermolecular Rauhut-Currier reaction

EurekAlert! - Dom, 05/21/2017 - 22:00
The first total synthesis of dimeric securinega alkaloid (-)-flueggenine C was completed via an accelerated intermolecular Rauhut-Currier (RC) reaction. The research team led by Professor Sunkyu Han in the Department of Chemistry succeeded in synthesizing the natural product by reinventing the conventional RC reaction.

Wearable vision systems reveal more than a 'highway in the sky'

EurekAlert! - Dom, 05/21/2017 - 22:00
Significant commercial investment in wearable vision systems for personal communications and entertainment is driving rapid advances in miniature optoelectronics components and consumer-driven applications. A special section in this month's issue of Optical Engineering, published by SPIE, the international society for optics and photonics, aims to help boost progress across development in automotive, industrial, and military applications.

Scientists develop test to identify best treatment for gonorrhea

EurekAlert! - Dom, 05/21/2017 - 22:00
Researchers from UCLA have developed a laboratory test that helps physicians determine which people with gonorrhea may be more treatable with an antibiotic that has not been recommended since 2007 because of concerns that the resistance to the drug was growing.

Social factors of patients affect hospital performance measures

EurekAlert! - Dom, 05/21/2017 - 22:00
A team of researchers led by a University of Colorado School of Medicine faculty member found that measures to evaluate readmission rates at children's hospitals would be more accurate if the social factors of the patients are included.

Two simple building blocks produce complex 3-D material

EurekAlert! - Dom, 05/21/2017 - 22:00
Northwestern University scientists have built a structurally complex material from two simple building blocks that is the lowest-density metal-organic framework ever made. Directed by design rules developed by the scientists, uranium atoms and organic linkers self-assemble into a beautiful crystal -- a large, airy 3-D net of very roomy and useful pores. The pores are so roomy, in fact, that the scientists have nestled a large enzyme inside a pore -- no small feat.

DNA vaccine protects against toxic proteins linked to Alzheimer's

EurekAlert! - Dom, 05/21/2017 - 22:00
A new DNA vaccine when delivered to the skin prompts an immune response that produces antibodies to protect against toxic proteins associated with Alzheimer's disease -- without triggering severe brain swelling that earlier antibody treatments caused in some patients.

Success of stem cell therapy for diabetes depends on pre-transplant immune condition

EurekAlert! - Dom, 05/21/2017 - 22:00
Researchers at the Center for Cell-Based Therapy at University of São Paulo (USP) show that the therapeutic effect is relatively short-lived in patients with more autoreactive lymphocytes before treatment.

Pulmonary Thrombosis-on-a-Chip provides new avenue for drug development

EurekAlert! - Dom, 05/21/2017 - 22:00
Researchers at the Wyss Institute have engineered a model of human pulmonary thrombosis using its Organ-on-a-Chip platform that mimics in vivo blood clot formation and confirms the transmission of inflammatory signals from the pulmonary epithelium to the vascular endothelium, providing a new model for investigation and treatment/prevention of pulmonary blood clots.

New research could help develop drugs to better address heart problems in diabetics

EurekAlert! - Dom, 05/21/2017 - 22:00
Research published in Experimental Physiology shows that diabetes-induced changes in heartbeat are primarily regulated by the β1-adrenoceptor. This discovery, once confirmed in humans, may lead to better treatment of heart problems in diabetics by enabling more targeted drugs to be produced.

Cultural backgrounds of media organizations affect international news coverage

EurekAlert! - Dom, 05/21/2017 - 22:00
Researchers examined the photographic news coverage of a visit Pope Francis made to Cuba to determine how major media outlets from different countries covered the international event. They found that the cultural values of the photojournalists' home countries affected the ways in which the pope's visit was framed by each media outlet.

Risk of interval colorectal cancers higher among African-Americans

EurekAlert! - Dom, 05/21/2017 - 22:00
An American Cancer Society study of Medicare enrollees finds the risk for interval colorectal cancers, cancers that develop after a colonoscopy but before the next recommended test, is higher for blacks than whites.

New insight into life-threatening childhood brain cancer
