BC Global Observatory uncovers striking economic and human cost in first continent-wide survey.

Americans may respect and admire how individual billionaires—think Oprah Winfrey or Bill Gates—made their billions, even as they rage against the "top 1%" as a group, new research finds.

Astronomers have used a planet-hunting satellite to see a white dwarf abruptly switching on and off for the first time.

New research from the Florida State University College of Medicine found that changes in the brain associated with Alzheimer’s disease are often visible early on in individuals with personality traits associated with the condition. The study focused on two traits previously linked to the risk of dementia: neuroticism, which measures a predisposition for negative emotions, […]

Attention-deficit hyperactivity disorder (ADHD) is a prevalent neurodevelopmental disorder impairing the quality of life of the affected individuals. The domestic dog can spontaneously manifest high hyperactivity/impulsivity and inattention which are components of human ADHD. Therefore, a better understanding of demographic, environmental and behavioural factors influencing canine hyperactivity/impulsivity and inattention could benefit both humans and dogs. ... We collected comprehensive behavioural survey data from over 11,000 Finnish pet dogs and quantified their level of hyperactivity/impulsivity and inattention. We performed generalised linear model analyses to identify factors associated with these behavioural traits. Our results indicated that high levels of hyperactivity/impulsivity and inattention were more common in dogs that are young, male and spend more time alone at home. Additionally, we showed several breed differences suggesting a substantial genetic basis for these traits. Furthermore, hyperactivity/impulsivity and inattention had strong comorbidities with compulsive behaviour, aggressiveness and fearfulness. Multiple of these associations have also been identified in humans, strengthening the role of the dog as an animal model for ADHD.

Anti-establishment sentiments are a key component of political opinion and behavior in the United States and are distinct from traditional indicators of political ideology, according to new research. "Especially with the ascendance of Trump, we witnessed a blending of left-right political concerns with antagonistic orientations toward the political establishment." ...

Most galaxies have a single nucleus -- does this galaxy have four? The strange answer leads astronomers to conclude that the nucleus of the surrounding galaxy is not even visible in this image. The central cloverleaf is rather light emitted from a background quasar. The gravitational field of the visible foreground galaxy breaks light from this distant quasar into four distinct images. The quasar must be properly aligned behind the center of a massive galaxy for a mirage like this to be evident. The general effect is known as gravitational lensing, and this specific case is known as the Einstein Cross. Stranger still, the images of the Einstein Cross vary in relative brightness, enhanced occasionally by the additional gravitational microlensing effect of specific stars in the foreground galaxy.
