A team of psychology researchers is providing one of the first comprehensive literature reviews on arrogance, as well as a way to classify the condition on different levels across a spectrum, similarly to how autism is diagnosed. The team acknowledges everyone seems to have some degree of arrogance, so in addition to the literature review, the researchers suggest a way to classify the different levels of arrogance a person could exhibit.
Read moreIn clinical trials of adults with Huntington's disease (HD) the Q-Suite Motor Assessment Tool (Q-Motor) has proven to be helpful to detect and quantitate subtle motor abnormalities. With the anticipated arrival of preventive gene therapies that will most likely be administered to young children known to be carriers of the HD mutation, it is crucial to have a means to evaluate motor abilities in children that is sensitive to the child's stage of development.
Read moreScientists have developed a forensic tracer that uses lead isotopes to detect and measure coal fly ash in dust, soil and sediments. Tests show the new tracer can distinguish between the isotopic signature of lead derived from coal ash and lead that comes from other major human or natural sources. Exposure to fly ash from dust, soil or sediments has been linked to numerous diseases and health concerns.
Read moreA clinical trial argues against the hypothesis that the diabetes drug metformin could help exercising seniors gain more muscle mass. The double-blind trial found that older adults who took metformin while performing rigorous resistance exercise training had smaller gains in muscle mass than the placebo group.
Read moreHuman population density and land use is causing changes in animal genetic diversity, according to new research. The research show that environmental changes caused by humans are leading to changes in genetic variation in thousands of species of birds, fish, insects, and mammals. The evidence for human impacts was most clear for insects and fish species.
Read moreMen with breast cancer are more likely to die than their female counterparts, across all stages of disease, with the disparity persisting even when clinical characteristics, such as cancer types, treatment and access to care are considered, according to a new study.
Read moreScientists have discovered a new lineage of specialized brain cells, called Hoxb8-lineage microglia, and established a link between the lineage and OCD and anxiety in mice. Their experiments proved that Hoxb8-lineage microglia prevent mice from displaying OCD behaviors. Additionally, they found that female sex hormones caused more severe OCD behaviors and induced added anxiety in the mice.
Read moreResearchers have invented a novel class of Digital-to-Analog (DAC) and Analog-to-Digital Converters (ADC) that can be entirely designed with a fully-automated digital design methodology.
Read moreAI reveals domain-geometry-driven differences in ferroelectric switching, important for next-generation computing; approach could be applied to electron microscopy, agriculture, astronomy and other systems mapped through hyperspectral imaging
Read moreAging can be delayed through lifestyle changes (physical exercise, restricting calorie intake, etc.). Researchers have elucidated the properties of a molecule in the blood – GDF11 – whose mechanisms were previously unknown. In a mouse model, they showed that this molecule could mimic the benefits of certain calorie restrictions – dietary regimens that have proven their efficacy in reducing cardiovascular disease, preventing cancer and increasing neurogenesis in the brain.
