Studies by scientists at British American Tobacco have shown that aerosol from potentially reduced-risk products (PRRPs), such as vapour and tobacco heating products (THPs), cause significantly less staining to tooth enamel, skin, cloth and wallpaper than does the smoke from conventional cigarettes.
The study results are presented today at the Global Forum on Nicotine in Warsaw, Poland.
The first time Vayu Maini Rekdal manipulated microbes, he made a decent sourdough bread. At the time, young Maini Rekdal, and most people who head to the kitchen to whip up a salad dressing, pop popcorn, ferment vegetables, or caramelize onions, did not consider the crucial chemical reactions behind these concoctions.
Better community education and communication are critical for increasing levels of blood donation among minorities, according to a study by researchers at Georgia State University and Georgia Southern University.
Nursing associate professor Regena Spratling in the Byrdine F. Lewis College of Nursing and Health Professions at Georgia State and her colleagues in the Georgia Southern University School of Public Health conducted the first systematic literature review of research on barriers and facilitators among minorities with blood donations.
The timing of a hurricane is one of the primary factors influencing its impact on the spread of mosquito-borne infectious diseases such as West Nile Virus, dengue, chikungunya and Zika, according to a study led by Georgia State University.
Based on preliminary results from a new Gemini Observatory survey of 531 stars with the Gemini Planet Imager (GPI), it appears more and more likely that large planets and brown dwarfs have very different roots.
We often look to people's faces for signs of how they're thinking or feeling, trying to gauge whether their eyes are narrowed or widened, whether the mouth is turned up or down.
A new mathematical model that predicts which choices people will make in the Iowa Gambling Task, a task used for the past 25 years to study decision-making, outperforms previously developed models. Romain Ligneul of the Champalimaud Center for the Unknown in Portugal presents this research in PLOS Computational Biology.
Researchers from North Carolina State University have found a gene that gives Salmonella resistance to antibiotics of last resort in a sample taken from a human patient in the U.S. The find is the first evidence that the gene mcr-3.1 has made its way into the U.S. from Asia.
SALT LAKE CITY - A personalized prognosis for patients diagnosed with triple-negative breast cancer was the goal of a new study by Katherine Varley, PhD, researcher at Huntsman Cancer Institute (HCI) and assistant professor of oncological sciences at the University of Utah.
Research undertaken at the University of Adelaide overturns the belief that turning your crooked teeth into a beautiful smile will automatically boost your self-confidence.
The study, carried out by Dr Esma Dogramaci and Professor David Brennan from the University of Adelaide's Dental School, followed 448 13-year-olds from South Australia in 1988 and 1989. By the time that they turned 30 in 2005 and 2006 more than a third of them had received orthodontic treatment.
OAK BROOK, Ill. - Cardiac MRI has a pivotal role to play in the diagnosis of cocaine-induced cardiovascular diseases, according to an article published in the journal Radiology: Cardiothoracic Imaging.
A combination of six antibodies can successfully prepare mice to accept blood and immune stem cells from an immunologically mismatched donor, according to a study by researchers at the Stanford University School of Medicine.
The recipient animals can then accept an organ or tissue transplant matching that of the donor stem cells without requiring ongoing immune suppression.
Amphibians, such as frogs and newts, form their hands and feet by differential growth. It means that differences in the growth rate between the digital and interdigital regions will determine the final proportions of these structures. In contrast, amniotes such as birds and mammals employ also cell death to shape their limbs. Removing part of the limb tissue by cell death allowed for the evolution of a great variety of limb shapes, such as the lobed fingers of coots, and even removal of some fingers in horses and camels (Figure 1).
Spending at least two hours a week in nature may be a crucial threshold for promoting health and wellbeing, according to a new large-scale study.
Cold Spring Harbor, NY -- Pancreatic ductal adenocarcinoma (PDAC) is the fourth leading cause of cancer-related deaths in the world. Mostly chemoresistant, PDAC so far has no effective treatment. Understanding the connective tissue, called stroma, that surrounds, nurtures, and even protects PDAC tumors, is key to developing effective therapeutics.
