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.
ANN ARBOR, Mich. - Vaccinating babies against a virus that causes childhood "stomach flu" greatly reduces their chance of getting so sick that they need hospital care, a new study shows.
But the study also reveals a surprise: Getting fully vaccinated against rotavirus in the first months of life is associated with a lower risk of developing Type 1 diabetes later on.
DURHAM, N.C. - A team led by Duke Health scientists has identified a cellular process that could lead to the development of safer and more effective vaccines that protect pregnant women as well as their newborns from dangerous infections.
Publishing online June 13 in the journal Cell, the researchers describe a previously unidentified route for antibodies to be transferred from the mother to the fetus, illuminating a potential way to capitalize on this process to control when and how certain antibodies are shared.
WASHINGTON -- People who feel financially vulnerable may be prone to believing incorrectly their success in negotiations must come at the expense of the other party, leading them to ignore the potential for more cooperative and mutually beneficial options, according to research published by the American Psychological Association.
Sickle cell disease is a hereditary disorder that affects red blood cells, distorting their natural disc shape into a crescent moon or "sickle" shape. Normal red blood cells move freely through small vessels throughout the body to deliver oxygen. With sickle cell disease, the misshapen red blood cells become hard and sticky, making it difficult for them to move through blood vessels. They eventually block the flow and break apart. This process results in a number of problems including severe chronic pain, stroke, organ damage, spleen dysfunction, heart failure and even death.
Optoelectronic integration offers a promising strategy to simultaneously obtain the merits of electrons and photons when they serve as information carriers, including high-density communication and high-speed information processing, paving the way for the next-generation integrated circuits (ICs). The ever-increasing demand on bandwidth and information density in ICs call for the micro/nano functional devices capable of being fabricated in three-dimensional (3D) ICs, which is desirable for their improved performance in data processing under lower consumption.
NEW YORK, June 13, 2019 - Many people associate dopamine with reward or attention. Some might think of the part it plays in addiction, or Parkinson's disease, which kills off dopamine-making neurons.
