Researchers confirm theoretical predictions and discover edge-states in graphene nanoribbons, exhibiting unique electronic properties. The findings open the possibility of building quick-acting, energy-efficient nanoscale devices from graphene-nanoribbon switches.
Research at DDW 2011 presents innovative detection practices to increase liver disease detection rates and prevent premature death. Vaccination rates against hepatitis A and B in patients with chronic liver disease are low, highlighting the need for increased vaccination efforts.
A new study found a strong correlation between income levels and celiac disease diagnosis accuracy, with higher-income individuals more likely to receive accurate diagnoses. The study's authors suggest that socioeconomic factors, including health literacy and access to information, may contribute to this disparity.
Researchers developed an iPhone application that can diagnose stroke with high accuracy, using noncontrast computed tomography (NCCT) and CT angiogram head scans. The technology allows doctors to analyze images in real-time from anywhere, providing critical access to specialists.
A potential celiac disease vaccine, Nexvax2, has demonstrated safety and efficacy in a Phase I clinical trial, with the goal of treating the autoimmune disease by desensitizing patients to specific gluten peptides. The vaccine is expected to enter Phase II trials within the next year.
Research finds UK betting shops are drawing in a new type of customer, particularly young males and ethnic minority groups, with the use of fixed odds betting terminals. These machines are associated with higher risks of problem gambling due to their fast-paced nature and high stakes.
Researchers at Mayo Clinic's Zebrafish Core Facility successfully switched individual genes on and off in zebrafish, allowing them to observe embryonic and juvenile development. This breakthrough enables the study of protein function and its relation to health problems like cancer, heart attacks, and addiction.
Researchers from the University of Hawaii at Manoa used GPS data to find that a section of the eastern Andes is locked in place, allowing stress to build up and potentially leading to large earthquakes. The study suggests that earthquakes with magnitudes up to 8.9 are possible in the region.
A study found that celiac disease is more common among Massachusetts children born in the spring or summer, suggesting a link between gluten introduction timing and birth season. The study suggests rethinking gluten introduction for some children based on their birth season.
Research at Digestive Disease Week 2011 reveals that a high carbohydrate intake increases the risk of developing gallstones during pregnancy. Additionally, symptoms of lactose intolerance may actually be linked to somatoform disorders, which can lead to counterproductive behaviors like restrictive diets.
Research by Dr. Wei Ji Ma and colleagues found that the brain can perform visual search tasks near optimally, even in complex environments. By weighing different pieces of visual information based on reliability, humans can quickly integrate data to detect targets.
The American Society for Gastrointestinal Endoscopy (ASGE) held its seventh annual Crystal Awards dinner to recognize outstanding contributions to endoscopy. The event honored recipients of the Rudolf V. Schindler Award, Distinguished Service Award, and other prestigious awards.
A randomized trial found women are at more than double the short-term risk of stroke following carotid stenting compared to traditional surgery. This study suggests that sex should be considered when choosing treatment options for carotid disease, as men show little difference in stroke risk between procedures.
Researchers investigated zombie ants in Thailand's rainforest, finding they were manipulated by the fungus into dying at optimal conditions for reproduction. The fungus causes muscle atrophy, central nervous system damage, and 'lock jaw', forcing infected ants to bite leaves to release spores.
Researchers at UC Berkeley have developed a graphene-based optical device that can switch light on and off, enabling faster data transmission. The technology has the potential to revolutionize high-speed communications and computing, allowing for faster data streaming and processing.
