In stressful jobs, depression risk rises with hours worked, study in new doctors finds

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...

New data registry collects evidence in cardiogenic shock patients

The American Heart Association has created new registry will help researchers, clinicians and regulators to better understand the clinical symptoms of shock types, treatment patterns and outcomes. The registry will provide a foundation for working toward improving the quality and consistency of care in patients in U.S. hospitals with cardiogenic shock symptoms.

NASA's Webb takes star-filled portrait of pillars of creation

NASA's James Webb Space Telescope has captured a lush, highly detailed landscape -- the iconic Pillars of Creation -- where new stars are forming within dense clouds of gas and dust. The three-dimensional pillars look like majestic rock formations, but are far more permeable. These columns are made up of cool interstellar gas and dust that appear -- at times -- semi-transparent in near-infrared...

Engineers record neurons to pinpoint synaptic links

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

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...

Deeper understanding of the icy depths

Scientists have uncovered new details of how ice forming below the ocean surface in Antarctica provides cold dense water that sinks to the seabed in an important aspect of global water circulation.

Antigen testing for COVID can be a useful tool for healthcare systems' return-to-work guidance

New findings demonstrate how the rapid antigen test can be used to triage healthcare workers for returning to work during periods of acute staffing shortages during COVID surges. They also show that a majority of health care workers remain antigen positive five to seven days following COVID-19 infection. Other healthcare systems can also look to these findings as they implement their own...

Study: Live chat boosts college women's class participation

Women much more enthusiastically embraced the live chat function during pandemic Zoom classes than men, according to a new University of Nevada, Las Vegas (UNLV) study. Researchers hope the data could be a key to broadening underrepresented groups' access to STEM disciplines as colleges incorporate technology into hybrid and even in-person courses.
