The more hours someone works each week in a stressful job, the more their risk of depression rises, a study in new doctors finds. Working 90 or more hours a week was associated with changes in depression symptom scores three times larger than the change in depression symptoms among those working 40 to 45 hours a week. A higher percentage of those who worked a large number of hours had scores high...

Patients believe in psychotherapy more when practitioners demonstrate warmth and competence
- ScienceDaily
- 22/10/19 23:22
Therapy is informed not just by the practitioner's expertise but also by the patient's expectations about that expertise and how likely they are to benefit from it. Research suggests that therapists who demonstrate both warmth and competence can shape those expectations by inspiring more positive beliefs about the effectiveness of therapy.

The Laramie chickensage is unusual among the hundreds of species of sagebrush, most of which are primarily pollinated by the wind.
Engineers record neurons to pinpoint synaptic links
- ScienceDaily
- 22/10/19 23:22
Neuroengineers were able to map the locations and activity of up to 1 million potential synaptic links in a living brain thanks to a new 3D electrode array that records the split-second evolution of electrical pulses in tens of thousands of neurons in a cubic millimeter of brain tissue.
Novel PET imaging agent detects earliest signs of Alzheimer's disease
- ScienceDaily
- 22/10/19 23:22
A new highly selective PET imaging agent can detect the presence of overexpressed monoamine oxidase-B (MAO-B) in cognitively unimpaired individuals with high beta amyloid -one of the earliest signs of Alzheimer's diseas-according to new research. The radiotracer, 18F-SMBT-1, allows for a better understanding of the role of inflammation in Alzheimer's disease, which can enable more accurate staging...
