Tracking influenza vaccination of healthcare personnel through an automated system increased vaccination compliance and reduced workload burden on human resources and occupational health staff, a study shows.
Frying is one of the world's most popular ways to prepare food -- think fried chicken and french fries. Even candy bars and whole turkeys have joined the list. But before dunking your favorite food in a vat of just any old oil, consider using olive. Scientists report that olive oil withstands the heat of the fryer or pan better than several seed oils to yield more healthful food.
Drawing blood and testing it is standard practice for many medical diagnostics. As a less painful alternative, scientists are developing skin patches that could one day replace the syringe. Scientists now they have designed and successfully tested, for the first time, a small skin patch that detected malaria proteins in live mice. It could someday be adapted for use in humans to diagnose other diseases, too.
Action-packed science-fiction movies often feature colourful laser bolts. But what would a real laser missile look like during flight, if we could only make it out? How would it illuminate its surroundings?
Major leaks from oil and gas pipelines have led to home evacuations, explosions, millions of dollars in lawsuit payouts and valuable natural resources escaping into the air, ground and water. Scientists say they have now developed a new software-based method that finds leaks even when they're small, which could help prevent serious incidents -- and save money for customers and industry.
Scientists have described a way to convert human skin cells directly into a specific type of brain cell affected by Huntington’s disease, an ultimately fatal neurodegenerative disorder. Unlike other techniques that turn one cell type into another, this new process does not pass through a stem cell phase, avoiding the production of multiple cell types, report researchers.
Complex biochemical signals that coordinate fast and slow changes in neuronal networks keep the brain in balance during learning, according to an international team of scientists. Neuronal networks form a learning machine that allows the brain to extract and store new information from its surroundings via the senses. Researchers have long puzzled over how the brain achieves sensitivity and stability to unexpected new experiences during learning -- two seemingly contradictory requirements.
The quality of diagnostic staging using biopsy in patients with bladder cancer is directly linked with survival, meaning those that don’t get optimal biopsies are more likely to die from their disease, researchers have shown for the first time.
Taking steps from an early age to improve childhood education skills could raise overall population levels of academic achievement by as much as 5%, and reduce socioeconomic inequality in education by 15%, according to international research.
A nanoparticle has been developed to deliver a melanoma-fighting drug directly to the cancer. Delivering cancer drugs directly to tumors is difficult. Scientists are working on new approaches to overcome the natural limitations of drugs, including loading them into nanoparticles.
By a tremendous margin – over 95 percent – older Americans choose to live at home or with relatives. Families making that choice should consider seeking the assistance of a geriatric specialist, especially when they see changes in their loved one’s behavior, an expert says.
More mental health screenings and services are needed for juvenile offenders, experts say. The intent of this study was to implement mental health screening; determine the percentage of youth detainees in need of services; assess the availability and extent of detention center mental health follow-up and referral services; and assess whether a disparity exists due to the size and geographic location of the detention center.
People can eat potatoes and still lose weight, a new study demonstrates. The study sought to gain a better understanding of the role of calorie reduction and the glycemic index in weight loss when potatoes are included in the diet. “Some people have questioned the role of potatoes in a weight loss regimen because of the vegetable’s designation as a high glycemic index food,” explained the lead investigator of the study. “However, the results of this study confirm what health professionals and nutrition experts have said for years: it is not about eliminating a certain food or food groups, rather, it is reducing calories that count.”
Unmanned aerial vehicles, or drones, can collect detailed information in real time at relatively low cost for ecological research. In a new article, experts demonstrate that drones can be used to understand how environmental factors influence the spread of infectious diseases.
What does it mean to simulate the human brain? Why is it important to do so? And is it even possible to simulate the brain separately from the body it exists in? These questions are discussed in a new paper.
Just in time for flu season, a new study of 'the mother of all pandemics' could offer insight into infection control measures for the flu and other epidemic diseases. Researchers studied the evolution of the 1918 influenza pandemic, aka the "Spanish flu." In 1918, the virus killed 50 million people worldwide, 10 to 20 million of whom were in India. In the United States alone, the Spanish flu claimed 675,000 lives in nine months.
Major antioxidant compounds that determine tea health properties and taste fell up to 50 percent during an extreme monsoon, a study concludes. The findings are based on samples taken from tea gardens in southwest China. The researchers collected samples from two extreme weather events -- an extreme drought and an extreme monsoon -- and performed a chemical analysis of the samples.
Researchers may have hit upon an answer to a climate-change puzzle that has eluded scientists for years, namely why glaciers in the Karakoram range of the Himalayas have remained stable and even increased in mass while glaciers nearby and worldwide have been receding. Understanding the 'Karakoram anomaly' could help gauge the future availability of water for hundreds of millions of people.
Negative feelings about one's own weight, known as internalized weight bias, influence the success people have after undergoing weight loss surgery, according to research. The study is considered the first and only study to examine internalized weight bias in relation to post-surgical weight loss success in adults.
Some scientists share better than others. While astronomers and geneticists embrace the concept, the culture of ecology still has a ways to go. New research explores the paradox that although ecologists share findings via scientific journals, they do not share the data on which the studies are built, said a co-author of the paper.
